Donavon and three friends go to a fair. They each spend one half of their money on rides. ​ Then, they each spend​ $3 on food. At the end of the​ day, Donavon and his friends have a total of​ $8 remaining. How much money did each person bring to the​ fair?

Answers

Final answer:

The question is a mathematics problem requiring solving a two-step equation to find out how much money each person started with, and through logical deduction and equation solving, it's found that every person brought $10 to the fair.

Explanation:

The subject of this problem is Mathematics, and it involves solving a two-step equation to find the initial amounts of money each person had. Let's simplify it step by step:

Recognize that there are 4 individuals (Donavon and his 3 friends) spending money. Let's designate the amount of money each person started with as 'X.' They each spend one half of their money on rides. That means they each have X/2 money left.They each then spend $3 on food, so now they each have X/2 - 3 dollarsAfter these expenditures, they're each left with a total of $8. Because there's 4 of them and they each have the same amount left, we have the equation 4 *(X/2 - 3) = 8.Solving this equation, we find that X, the amount of money each person started with, equals $10.

75.2 in. ≈≈
cm

Answers

Final answer:

To convert 75.2 inches to centimeters, multiply it by the conversion factor of 2.54 cm per inch. 75.2 inches is approximately 191.01 centimeters when rounded to the nearest hundredth.

Explanation:

To convert inches to centimeters, you need to use the conversion factor 2.54 cm = 1 inch. The given measurement is 75.2 inches, and you are asked to convert this to centimeters.

You start by setting up the proportion as follows:

1 inch = 2.54 cm75.2 inches = x cm

To find x, you multiply 75.2 by 2.54:

75.2 inches * 2.54 cm/inch = 191.008 cm

Then round this off to the nearest hundredth (if necessary) to obtain:

75.2 in. ≈ 191.01 cm

A cafe only sells two types of sandwiches, turkey and steak. The cafe charges $4 for turkey sandwiches and $6 for steak sandwiches. Last month, the cafe sold $4524 worth of sandwiches. The cafe sold a total of 925 sandwiches.

How many turkey sandwiches did they sell?

Enter your answer in the box.

Answers

X = number of turkey sandwiches

Y = number of steak sandwiches

 

X   + Y    = 925 total sandwiches sold

4X + 6Y = 4524 dollars made

 

-4(X + Y = 925)

 

-4X + (-4Y) = -3700

 4X +  6Y    = 4524

           2Y    = 824

Y = 412

 

X + Y = 925

X + 412 = 925

X = 513 turkey sandwiches

Answers

Visualize 4 sets of circles: Each set consists of 2 large blue circles, each containing 2 smaller green circles. In total, there are 4 large blue circles and 8 smaller green circles, representing the result of multiplying 4 by the inner parenthesis (2x2).

Visualizing 4x(2x2) with Circles:

Representing the Inner Parenthesis (2x2):

Imagine two blue circles, side-by-side.

Inside each blue circle, draw two smaller green circles, also side-by-side.

This group of circles (two large blue circles, each containing two smaller green circles) represents the part inside the parenthesis, "2x2."

Multiplying by 4:

Imagine replicating the entire group of circles from step 1 four times.

You now have a total of four groups, each containing two blue circles with two green circles inside each.

Visualization Summary:

You should have a total of 16 circles:

4 large blue circles.

8 smaller green circles (2 inside each blue circle).

These circles are grouped into 4 sets, representing the multiplication of the entire parenthesis (2x2) by 4.

An amount of $8,000 is invested at a simple interest rate of 1.5%. What is the total amount after 3 years?

Answers

I=PRT
P=8000
R=0.015
T=3

I=8000*0.015*3=360

total amount=8000+360=$8360

For simple interest, the interest for each year is calculated on the initial principal itself.
So, for a period of 3 years, the total interest will be

(1.5% of 8000)×3=1.5⋅3⋅8000100=360

So the total amount at the end of the period

=Principal+Interest=8000+360=8360

a railroad car container can hold 42,000 pounds. Mr.Evans wants to ship 90 ovens and some freezers in the same container. If each freezer weighs 600 pounds, how many freezers can be shipped in the container? Explain

Answers

The amount of freezers that can be shipped is 70. I'm not completely sure, because I do not know how many pounds the ovens are. But to get the answer, just simply divide 42000 by 600.

Answer:

40

Step-by-step explanation:

We are given that

A railroad container can hold weight=42,000 pounds

Total number of ovens for ship=90

Weight of each oven=200 lbs

Weight of each freezer=600 pounds

We have to find the number of freezer can be shipped in the container.

Let x be the number of freezer can be shipped in the container.

According to question

[tex]42000=90(200)+600x[/tex]

[tex]42000=18000+600x[/tex]

[tex]600x=42000-18000[/tex]

[tex]600x=24000[/tex]

[tex]x=\frac{24000}{600}=40[/tex]

Hence, 40 freezer can be shipped in the container.

To prove

Let us assume that the  string will Mellisa have left over be x .

As given

Melissa needs 3.87 feet of string to use as a border for her poster.

Melissa finds a piece of string that is 4.25 feet long.

Than the equation is write in the form

x = 4.25 - 3.87

x = 0.38 feet

Therefore the  string will Mellisa have left over be  0.38 feet .

Hence proved

The length of string Mellisa will have left over is 0.38 feet

From the question,

We are to determine how much string Mellisa would have left over.

From the given information

Melissa needs 3.87 feet of string to use as a border for her poster.

Then,

She finds a piece of string that is 4.25 feet long.

if the sum of the interior angles of a square is 360,write an equation to show of one interior angle.

Answers

The interior angle would be 360* degrees.. but i think 900* hope i could help.

Final answer:

To find the measure of one interior angle of a square, divide the total sum of interior angles, 360 degrees, by the number of angles in a square, which is four. The resulting equation is x = 360° ÷ 4, revealing that each angle measures 90 degrees.

Explanation:

The question asks us to write an equation to describe the measure of one interior angle of a square given that the sum of interior angles of a square is 360 degrees.

A square has four equal interior angles. To find the measure of one angle, we can divide the total degrees by the number of angles.

We can set up the equation as follows: Let x be the measure of one interior angle of a square. Then we write the equation x = 360° ÷ 4. When we calculate it, x equals 90 degrees, which means each interior angle of a square is 90 degrees.
