Answer:

-5,120

Step-by-step explanation:

The pattern is increasing by x*2

I would say -100

You would find this out by identifying your 'a' which is the first number of the sequence, in this case it is -5

Then you would find the common ratio. You do that by dividing any two of the numbers after your 'a' For this one I chose to divide -20 by -10 and that gets you 2.

You would multiply those together, getting you -10.

So, from here you would put the term you are trying to find (in this case it is the 11th term) and subtract it by one

11-1=10

Lastly, you would multiply your -10 by 10 and get yourself a -100

Formula: nth term =  a1^n-1

Hope this helps :) Sorry if it is kinda confusing...

Final answer:

The percent increase in Minerva's bicycle price is calculated by subtracting the original price from the new price, dividing by the original price, and then multiplying by 100%. The calculation results in a 400% increase.

Explanation:

The percent increase in the price of the bicycle that Minerva bought and sold is calculated using the formula for percent change, which is (New Price - Original Price) / Original Price times 100%. In this case, the original price is $10 and the new price is $50.

To calculate the percent increase:
($50 - $10) / $10 times 100% = $40 / $10 times 100% = 4 times 100% = 400%.

Therefore, the correct answer is 400%, which is option A.

Answer: 7.97 meters

Step-by-step explanation:

You must use the formula for calculate the area of a circle, which is:

[tex]A=r^2\pi[/tex]

Where r is the radius of the circle.

The diameter of the circle is:

[tex]D=2r[/tex]  

Solve for r from  [tex]D=2r[/tex]  

[tex]r=\frac{D}{2}[/tex]

Substitute the area and [tex]r=\frac{D}{2}[/tex] into the first equation and solve for the diameter. Then you obtain:

[tex]50m^2=(\frac{D}{2})^2\pi\\\\50m^2=\frac{D^2}{4}\pi\\\\D=\sqrt{\frac{4*50m^2}{\pi}}\\D=7.97m[/tex]

Answer:

The  diameter of a circle that has 50 square meters = 7.98 m

Step-by-step explanation:

Formula

Area of circle = πr²

Where 'r' is the radius of circle

Diameter of circle d = 2r

It is given that area of circle = 50 square meters

To find the radius of circle

we have,

Area of circle = πr² = 50

r² = 50/π = 50/3.14 = 15.924

r = √15.924 = 3.99

To find the diameter of circle

Diameter = 2r = 2 * 3.39 = 7.98 m

Step-by-step explanation:

To find the area of the unshaded portion of a figure containing a trapezoid and a rhombus, calculate the area of each figure first using their respective formulas. Subtract the area of the overlapping (shaded) region from the total to find the area of the unshaded portion.

The problem asks to find the area of the unshaded portion of a figure, which includes a trapezoid and a rhombus. Since we don't have the specific values of the sides and heights of each figure, a general approach would be to calculate the area of each figure first, then subtract the area of the shaded (overlapping) region from it.

The formula for the area of a trapezoid is A = 1/2 (a+b)h, where 'a' and 'b' are the lengths of the parallel sides and 'h' is the height. For the rhombus, the formula is A = 1/2 (d1 * d2), where 'd1' and 'd2' are the diagonals.

Assuming you can measure and determine the shaded region, you would compute its area as well and subtract this from the total of the previous two calculations. This would give you the area of the unshaded portion.

1.7 ft2 If the surface area is 6.8 ft2 then 1.7ft2 x 4 =6.8FT2

The area of each Triangle is 1.7 ft².

A 3-dimensional solid prism's surface area is determined by the form of its base. A prism's surface area is the total area occupied by the prism's faces. A prism is a flat-faced polyhedron. It lacks curves.

The surface area of a prism is the amount of total space occupied by the prism's flat faces. Determining a prism's surface area entails calculating the total space occupied by all the faces of that particular type of prism or the sum of the areas of all faces (or surfaces) in a 3D plane.

We have

Surface Area = 6.8 ft²

As, the Figure have 4 Triangle.

Then, the Area of each Triangle

= 6.8 / 4

= 1.7 ft²

Thus, the required Surface Area is 1.7 ft².

Answer: B. y = 1.560x - 4.105*****

Answer:

Option B.

Step-by-step explanation:

The general equation of best fit line is

[tex]y=mx+b[/tex]              .... (1)

where, m is slope and b is y-intercept.

[tex]m=\frac{\sum_{i=1}^nx_iy_i-n\overline{x}\overline{y}}{\sum_{i=1}^nx_i^2-n\overline{x}^2}[/tex]

[tex]b=\overline{y}-b\overline{x}[/tex]

Answer:

2 gallons

Step-by-step explanation:

So say we make everything into cups. We know there is 4 cups in a quart and 2 cups in a pint. So if we do the math you are really adding

4 cups + 4 cups + 8 cups + 16 cups

So that  would be 32 cups.

We also know there is 16 cups in a gallon. Since we know that then we can do

32 cups ÷ 16 cups

That would be 2 gallons!

Hope this helps!

Final answer:

Jeff makes 2 gallons of fruit punch by converting all the liquid measurements to pints and then summing them up to convert to gallons.

Explanation:

To determine how many gallons of fruit punch Jeff makes, we need to convert all the measurements to the same unit and then add them together. Here are the conversions we'll use:

1 quart = 2 pints

1 pint = 2 cups

1 gallon = 4 quarts

1 gallon = 8 pints

1 gallon = 16 cups

Now let's convert everything to pints since most of the units provided are in pints:

Orange juice: 1 quart = 2 pints

Pineapple juice: 2 pints

Tropical punch: 8 cups = 4 pints

Ginger ale: 8 pints

Add all the pints together:

2 pints (orange juice) + 2 pints (pineapple juice) + 4 pints (tropical punch) + 8 pints (ginger ale) = 16 pints total

Now convert pints to gallons:

16 pints ÷ 8 pints/gallon = 2 gallons

So, Jeff makes 2 gallons of fruit punch.

Answer:

-3x

Step-by-step explanation:

Combine like terms (terms with the same amount of variables). Note that + x = + 1x. First add, then subtract:

2x + x = 3x

3x - 6x = -3x

-3x is your answer.

~

Answer:

6x

Step-by-step explanation:

x = -4

Let the number = x (set up an equation)

2x = -3x - 20

add 3x to both sides

5x = -20

divide by 5 on both sides

x = -4

The question involves creating and solving an algebraic equation. By interpreting the word problem, we create the equation 2x = -3x - 20. Solving this equation, we find that the number in question is -4.

The subject matter here is algebra, which falls under Mathematics. From the question, we can create an algebraic equation to find the number. Since the product of the number and 2 is 20 less than the product of the number and -3, we can write this as 2x = -3x - 20, with 'x' representing the unknown number. Solving this equation for x, we add 3x to both sides, turning the equation into 5x = -20. Dividing both sides by 5, we find that x = -4. So, the number is -4.

Step-by-step explanation:

Observing the figure

we know that

[tex]106\°+x=180\°[/tex] ----> by supplementary angles

Solve for x

[tex]x=180\°-106\°=74\°[/tex]

The solution to the given equation is x = -7/9, after simplifying and solving for x.

To simplify the equation -4(x + 4x) = 2(2 - x) + 10, start by combining like terms within the parentheses: -4(5x) = 2(2 - x) + 10. This leads to -20x = 4 - 2x + 10. Further simplifying, you get -20x = 14 - 2x. Now, add 2x to both sides to eliminate the variable on the right, resulting in -18x = 14. To isolate x, divide both sides by -18, yielding x = -14/18, which can be further reduced to x = -7/9. In summary, the equation simplifies to x = -7/9 after a series of steps.

f(x)⁻¹ = x³ + 2

Step-by-step explanation:

Find the inverse of f(x) = ∛(x - 2).

The first step is to let f(x) = y

y =  ∛(x - 2)

Then make x the subject of the formula

y³ =  [∛(x - 2)]³

y³ = x - 2

x = y³ + 2

∴ f(x)⁻¹ = y³ + 2

Replacing y with x we have.

f(x)⁻¹ = x³ + 2

To find out how much ribbon is left after using 1/2 yard from a piece that is 7/8 yard long, convert 1/2 yard to 4/8 and subtract from 7/8, leaving you with 3/8 yard of ribbon remaining.

To determine how much ribbon will remain after using 1/2 yard for a craft project from a piece that measures 7/8 yard, you need to subtract the amount used from the total length you have. Since we are working in yards, ensure both amounts are in the same units. Here are the steps to find the remaining ribbon:

Start with the total length of ribbon: 7/8 yard.

Subtract the length of ribbon used for the project: 1/2 yard.

Convert 1/2 yard to an equivalent fraction with a denominator of 8, which is 4/8 yard.

Subtract 4/8 yard from 7/8 yard to find the remaining length.

7/8 yard - 4/8 yard = 3/8 yard remaining.

So, after using 1/2 yard of ribbon for a craft project, you will have 3/8 yard of ribbon left from the original 7/8 yard piece.
