The Area of the Ferris wheel is 31400 Square feet
Step-by-step explanation:
The AREA formula for a circle:
The Area formula for the circle is [tex]\pi r^2[/tex]
where
r is the radius of the circle
The area of the Ferris Wheel:
The Height of the Ferris wheel = 200 foot
Here height of the Ferris wheel is the diameter
So the Diameter = 200
Then Radius =[tex]\frac{200}{2}[/tex] = 100 foot
Now the area of the Ferris wheel is
=> [tex]\pi (100)^2[/tex]
=> [tex]\pi \times 10000[/tex]
=> 31400 square feet

James has pennies nickels and dimes in his bank he is has more than $1.60 and less than $2.00 in the bank there are 5 times as many pennies as dimes there is an equal number of nickels dimes what’s exact amount of money in his bank
James has pennies, nickles and dimes in his bank. he has more than $1.60 and less than $2.00 in the bank. there are 5 times as many pennies as dimes. there is an equal number of nickels and dimes. what is the exact amount of money in his bank?
Answer:
The exact amount of money in his bank is $ 1.8
Solution:
Let "p" be the number of pennies
Let "d" be the number of dimes
Let "n" be the number of nickels
Given that,
There are 5 times as many pennies as dimes
Number of pennies = 5 times the number of dimes
p = 5d ----------- eqn 1
There is an equal number of nickels and dimes
n = d -------- eqn 2
We know that,
value of 1 dime = 0.10 dollar
value of 1 nickel = 0.05 dollar
value of 1 penny = 0.01 dollar
The total value of coins is:
total value = d(0.10) + n(0.05) + p(0.01)
Substitute eqn 1 and eqn 2
total value = d(0.10) + d(0.05) + 5d(0.01)
total value = 0.2d
Given that he has more than $1.60 and less than $2.00 in the bank
Therefore, 0.2d must be greater than 1.60 and less than 2.00
Try for d = 8
total value = 0.2 x 8 = 1.6
But value must be greater than 1.6
Try for d = 9
total value = 0.2 x 9 = 1.8
Thus 1.8 is greater than 1.60 and less than 2.00
Therefore, the exact amount of money in his bank is $ 1.8
The width of a rectangle is 4 1/6 feet, and its area is 35 square feet. What is the perimeter of this rectangle?
The perimeter of rectangle is 25.13 feet
Solution:
Given that,
width of a rectangle = [tex]4\frac{1}{6} \text{ feet }[/tex]
Convert the mixed fraction to improper fraction
[tex]\rightarrow 4\frac{1}{6} = \frac{6 \times 4 + 1}{6} = \frac{25}{6}[/tex]
Therefore,
[tex]\text{width of rectangle } = \frac{25}{6} \text{ feet }[/tex]
Area of rectangle = 35 feet
The area of rectangle is given by formula:
[tex]area = length \times width[/tex]
Substituting the given values, we get
[tex]35 = length \times \frac{25}{6}\\\\length = 35 \times \frac{6}{25} = \frac{42}{5}[/tex]
Thus we get,
[tex]\text{length of rectangle } = \frac{42}{5} \text{ feet }[/tex]
The perimeter of rectangle is given as:
perimeter = 2(length + width)
[tex]perimeter = 2(\frac{42}{5} + \frac{25}{6})\\\\perimeter =2(8.4+4.167)\\\\perimeter = 2(12.567)\\\\perimeter = 25.13[/tex]
Thus perimeter of rectangle is 25.13 feet

The track team needs new uniforms. The students plan to sell plush toy hawks (the school mascot) for $5 each. The students find three companies on line that sell stuffed mascots. Company A sells 18 hawks for $49.14. Company B sells 12 hawks for $33.12. Company C charges $40.65 for 15 hawks. Which company has the Best Buy?
After calculating the cost per hawk for each company, Company C offers the best buy at $2.71 per hawk.
The goal is to find out which company offers the best buy for the plush toy hawks. To do so, we'll calculate the cost per hawk from each company and compare them.
Company A: 18 hawks for $49.14 so $49.14 ÷ 18 = $2.73 per hawkCompany B: 12 hawks for $33.12 so $33.12 ÷ 12 = $2.76 per hawkCompany C: 15 hawks for $40.65 so $40.65 ÷ 15 = $2.71 per hawkCompany C offers the lowest cost per hawk at $2.71, thus they have the best buy.

The solution to the system of linear equations 4x - 2y = 8 and y = (3/2)x - 2 is x = 4 and y = 4, found by substituting y in the first equation with the expression from the second equation and solving for x.
The student is asking to solve a system of linear equations. The equations provided are:
4x - 2y = 8
y = (3/2)x - 2
We will solve this system using substitution since the second equation is already solved for y. Here are the steps:
Substitute y in the first equation with the expression from the second equation: 4x - 2((3/2)x - 2) = 8.
Simplify the equation: 4x - 3x + 4 = 8.
Solve the simplified equation for x: x + 4 = 8, which leads to x = 4.
Substitute x back into the second equation to find y: y = (3/2)4 - 2.
Calculate the value of y: y = 6 - 2, which leads to y = 4.
The solution to the system of equations is x = 4 and y = 4.
Nadine and Calvin are simplifying the expression (StartFraction r Superscript negative 5 Baseline s Superscript negative 3 Baseline Over r Superscript 8 Baseline s Superscript negative 2 Baseline EndFraction) Superscript negative 4. Nadine claims the first step to simplify the expression is to raise the numerator and denominator to the power of 4 to get StartFraction r Superscript negative 20 Baseline s Superscript negative 12 Baseline Over r Superscript 32 Baseline s Superscript 8 Baseline EndFraction. Calvin claims the first step to simplify the expression is to apply the quotient of powers to get (r Superscript negative 13 Baseline s Superscript negative 1 Baseline) Superscript negative 4. Who is correct and why?
Answer:
Calvin's first step is to simplify the expression is to apply the quotient of powers to get (r Superscript negative 13 Baseline s Superscript negative 1 Baseline) Superscript negative 4 is the correct step
That is [tex](\frac{r^{-5}s^{-3}}{r^8s^{-2}})^{-4}=(r^{-13}s^{-1})^{-4}[/tex] Calvin's step is the correct step.Because this is the correct way to do simplify the rational expression. And also because Nadine made a blender mistake in her operations in step
Step-by-step explanation:
Given that Nadine and Calvin are simplifying the expression (StartFraction r Superscript negative 5 Baseline s Superscript negative 3 Baseline Over r Superscript 8 Baseline s Superscript negative 2 Baseline EndFraction) Superscript negative 4
Their expression can be written as below
[tex](\frac{r^{-5}s^{-3}}{r^8s^{-2}})^{-4}[/tex]
Nadine's first step is to simplify the expression is to raise the numerator and denominator to the power of 4 to get StartFraction r Superscript negative 20 Baseline s Superscript negative 12 Baseline Over r Superscript 32 Baseline s Superscript 8 Baseline EndFraction
That is [tex]\frac{r^{20}s^{12}}{r^{-32}s^8}[/tex]
Calvin's first step is to simplify the expression is to apply the quotient of powers to get (r Superscript negative 13 Baseline s Superscript negative 1 Baseline) Superscript negative 4
That is [tex]r^{-13}s^{-1}[/tex]
Now simplify the given expression to check whose step is correct:
[tex](\frac{r^{-5}s^{-3}}{r^8s^{-2}})^{-4}[/tex]
[tex]=(r^{-5}s^{-3}r^{-8}s^{2})^{-4}[/tex] ( using the property [tex]\frac{1}{a^m}=a^{-m}[/tex] )
[tex]=(r^{-5-8}s^{-3+2})^{-4}[/tex]
[tex]=(r^{-13}s^{-1})^{-4}[/tex]
Therefore [tex](\frac{r^{-5}s^{-3}}{r^8s^{-2}})^{-4}=(r^{-13}s^{-1})^{-4}[/tex]
Therefore Calvin's first step is to simplify the expression is to apply the quotient of powers to get (r Superscript negative 13 Baseline s Superscript negative 1 Baseline) Superscript negative 4 is the correct step.
That is [tex](\frac{r^{-5}s^{-3}}{r^8s^{-2}})^{-4}=(r^{-13}s^{-1})^{-4}[/tex] Calvin's step is the correct step .Because this is the correct way to do simplify the rational expression.And also because Nadine made a blender mistake in her operations in step

Solve -3(2x-3)+10x=3q
Answer:
4x+9=3q
Step-by-step explanation:
-3(2x-3)+10x=3q
-6x+9+10x=3q
4x+9=3q
Answer:
q = 4/3x + 3
Step-by-step explanation:
-3(2x-3)+10x=3q
Multiply the -3 at the beginning by (2x - 3), the parenthesis
-6x + 9 + 10x = 3q
Now combine the like terms (add x's and variables separately)
(-6x + 10x) + 9 = 3q
4x + 9 = 3q
Divide both sides of the equation by 3
(4x + 9) ÷ 3 = q
4x/3 + 9/3 = q
Simplify
q = 4/3x + 3
Hope this helps :)
A 41-foot ladder is placed against a vertical wall of an apartment building. The base of the ladder is 9 feet from the base of the apartment building
The ladder reaches 40 feet up the wall.
41 squared (1681) minus 9 squared (81) is 1600. 40 is the square root of 1600.
The required distance between the top of the ladder and the ground is 40 feet.
What are Pythagorean triplets?In a right-angled triangle, its sides, such as hypotenuse, and perpendicular, and the base is Pythagorean triplets.
Here,
We can use the Pythagorean theorem to solve this problem. Let's call the distance from the base of the ladder to the wall "x", and let's call the length of the ladder "y".
According to the problem statement, we know that the ladder is 41 feet long and that the base of the ladder is 9 feet from the base of the apartment building.
y = 41 feet
x = 9 feet
We can use the Pythagorean theorem to solve for the distance between the top of the ladder and the ground. The Pythagorean theorem tells us that:
y² = x² + z²
where "z" is the distance between the top of the ladder and the ground. Plugging in the values we know,
(41 feet)² = (9 feet)² + z²
1681 = 81 + z²
1600 = z²
z = 40 feet
Therefore, the distance between the top of the ladder and the ground is 40 feet.

Above, a right triangle is removed from a rectangle. What is the area of the remaining figure?
[tex]48 {in}^{2} [/tex]
Answer: B . 48 in²
Step-by-step explanation:
First o all complete the block and find the area
The area of the completed block which looks like a rectangle
= L x B
= 9 x 6
= 54 in²
Step 2 : Find the area of the removed right angled triangle using the formula
= ¹/₂b x h
where the base is 3 in and the height is 4 in
= ¹/₂ x 3 x 4
= 6 in².
Therefore, to find the area of the remaining figure :
Area of the complete block less the area of the right angled triangle
= ( 54 - 6 ) in²
= 48 in²
The option therefore is B
Given that the points (-7, 6), (3, 6), (3, -6), and (-7, -6) are vertices of a rectangle, how much longer is the length than the width?
Answer:
Therefore,
The Length is longer than Width by 2 units.
[tex]Length=Width+2[/tex]
Step-by-step explanation:
Given:
Let the vertices of a Rectangle be
A ( -7 , 6)
B ( 3 , 6)
C ( 3 , -6)
D ( -7 ,-6)
To Find:
Relation between Length and Width = ?
Solution:
First we will find the Length and Width of Rectangle by Distance Formula ,
[tex]l(AB) = \sqrt{((x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2} )}[/tex]
Substituting the values we get
[tex]l(AB) = \sqrt{((3-(-7))^{2}+(6-6)^{2} )}[/tex]
[tex]l(AB) = \sqrt{((10)^{2}+(0)^{2} )}\\l(AB)=\sqrt{100}=10\ unit[/tex]
Similarly for BC we will have,
[tex]l(BC) = \sqrt{((3-3)^{2}+(-6-6)^{2} )}\\l(BC)=\sqrt{144}=12\ unit[/tex]
Now
Length = 12 units.
Width = 10 units.
Therefore,
Let Length be denoted by "L" and Width by "W" then
[tex]Length=Width+2=10+2=12\\\\\therefore L=W+2[/tex]
Therefore,
The Length is longer than Width by 2 units.
[tex]Length=Width+2[/tex]
Read the following scenarios. Who is better positioned to invest in bonds and why?
Jim is 24 and earns $62,000 a year. He wishes to invest for his newborn daughter's college education, which is 18 years away. Inflation is currently running at 4.1%, while real interest rates are rising.
Elizabeth is 63 years old and earns $137,000 a year. She wishes to invest for retirement, which is four years away. Inflation is currently running at 1.1%, while real interest rates are falling.
Select the best answer from the choices provided.
A.
Jim is better positioned to invest in bonds because he makes less and has longer before his investment matures.
B.
Jim is better positioned to invest in bonds because inflation is high.
C.
Elizabeth is better positioned to invest in bonds because she has less time before her investment matures.
D.
Elizabeth is better positioned to invest in bonds because real interest
rates are falling.
Answer:
The correct answer is A. Jim is better positioned to invest in bonds because he makes less and has longer before his investment matures.
Step-by-step explanation:
Jim is better positioned to invest in bonds for two reasons:
1. He can invest and take advantage of long-term bonds, between 12 and 20 years of term of maturity, that are those that usually have the highest interest rate. His goal is to invest and save for his daughter's college education, that is a newborn.
2. The real interest rates are rising. It means the bonds interest rates are clearly above the inflation rate in the country where Jim and his family live, having a better return for his investment.

the table shows the melting points of various elements is the absolute value of the melting point of neon greater than or less than the absolute value of the melting point of hydrogen
The absolute value of the melting point of neon greater than the absolute value of the melting point of hydrogen.
Step-by-step explanation:
In positive numbers, when the number gets larger then it is considered to be the greatest number.
for example: 20 > 5.
Meanwhile, For negative numbers, when the number gets larger then it is considered to be the smallest.
For example: -21 > - 40.
From the given table, we are given with the values of Melting point:
Hydrogen= -259.
Neon = -248.
Oxygen = -218.
We have to compare the melting points of hydrogen and neon,
⇒ - 248 > - 259.
Thus the melting point of the neon is greater than the melting point of the hydrogen.
