Final answer:

The question, which pertains to algebra, is asking for the solution to three equations involving three numbers. To solve the problem, we set up equations based on the information provided and then solve for the three unknowns. The solution is 10, 24, and 14.

Explanation:

This problem can be addressed using algebraic equations. We are given three unknown numbers a, b, and c. The problem provides us with the following information:

The average of a, b, and c is 16, which means the sum of the three numbers is 48 (because 16 * 3 = 48).
The second number, b, plus 20 equals the sum of the other two, a + c.
The third number, c, equals the sum of the first two numbers minus four, or a + b - 4.

Using these equations, we can solve for a, b, and c. Our steps are:

Substitute the values of a + b from the third equation into the second to get b + 20 = 2b - 4.
Solve this equation to get b = 24.
Substitute b = 24 into the first equation to get a + c = 24. This means a = c.
Substitute a = c into the third equation to get 2a = 28, or a = c = 14.

So, the three numbers are 10, 24, and 14.

Lucas paid for a pair of shoes with a $50 bill after the clerk added 9% tax to the purchase Lucas received $17.3 in change what was the price of the shoes not including the tax

Answers

answer:

$29.75

If Lukas paid for the shoes with $50, and got $17.30 back, the total price of the shoes with the tax was $32.70. Because we are trying to find the price of the shoes without the 9% tax, we calculate what 91% of 32.70 is, which is $29.757

Surface Area =

Help also explain please

Answers

To find surface area we can do 2(l)(w) + 2(l)(h) + 2(h)(w). l = length; w = width; h = height.

Next

Plug in 3 for length, 9 for height, and 13 for width. ( or however you’d like for width length height but only one number can be represented by h, l, and w.)

Then we add all the numbers
2(3)(13)+ 2(3)(9) + 2(9)(13) = SA (surface area)

78 + 54 + 234 = 366 in^2 or 366 sq. inches

Final answer:

The given dimensions are of a rectangular prism, and the surface area can be calculated using the formula 2lw + 2lh + 2wh, which gives 366 square inches for a prism with dimensions 13 inches, 9 inches, and 3 inches.

Explanation:

The numbers given, 3 inches, 9 inches, and 13 inches, are usually the dimensions of a rectangular prism, which is a type of box shape. The Surface Area of a rectangular prism is given by the formula 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height. Based on the numbers given, we can see that :

The length l=13 inches
The width w=9 inches
The height h=3 inches.

So, substitute these values into the formula:

Surface area = 2lw + 2lh + 2wh = 2(13x9) + 2(13x3) + 2(9x3) = 234 + 78 + 54 = 366 square inches.

This means the surface area of the box is 366 square inches. The surface area of a shape is a measure of the total area that the surface of the shape covers.

A college used a $5,000 gift from an alumnus to make two student loans. The first was at 5% annual simple interest to a nursing student. The second was at 7% annual simple interest to a business major. If the college collected $310 in interest the first year, how much was loaned to each student?

Answers

Hello,

Let x the amount allocated to the 1 student
Let y the amount allocated to the 2 student

x+y=5000
5/100 *x +7/100 * y =310

==>
5x+7y=31000 (1)
x+y=5000 (2)
(1)-5*(2)==>
2y=6000 ==>y=3000 and x=5000-3000=2000
Proof:
2000+3000=5000
5/100*2000+7/100*3000=100+210=310

A ball is dropped from a certain height. The function below represents the height f(n), in feet, to which the ball bounces at the nth bounce:f(n) = 9(0.7)n

What does the number 0.7 represent?

The ball bounces to 30% of its previous height with each bounce.
The height at which the ball bounces at the nth bounce is 0.3 feet.
The ball bounces to 70% of its previous height with each bounce.
The height from which the ball was dropped at the nth bounce is 0.7 feet.

Answers

Answer:

The ball bounces to 70% of its previous height with each bounce.

Step-by-step explanation:

In physics terminology, the number 0.7 is the coefficient of restitution. It is the ratio of the height of bounce (n+1) to the height of bounce (n).

The meaning of the number is that the ball bounces to 70% of the height of the previous bounce.

Answer:

The ball bounces to 70% of its previous height with each bounce.

Step-by-step explanation:

A ball is dropped from a certain height. The function below represents the height f(n), in feet, to which the ball bounces at the nth bounce:

f(n) = 9(0.7)n

Solve the equation. If there is no solution, write no solution. 2|n| – 12 = 16

Answers

Add 12 to both sides

2|n| = 16 + 12

Simplify 16 + 12 to 28

2|n| = 28

Divide both sides by 2

|n| = 28/2

Simplify 28/2 to 14

|n| = 14

Break down the problem into these 2 equations

n = 14

-n = 14

Solve the 1st equation: n = 14

n = 14

Solve the 2nd equation: -n = 14

n = -14

When you collect all solutions;

n = ±14
