1 answer:

7 0

The answer is : 5 .

Step by step solution:
Let the width of the rectangle be x.

Width : x
Length : x + 2

x + x + 2 + x + x +2 = 24
4x + 4 = 24
4x = 24-4
4x = 20
x= 20/4
x=5

Harper has $15.00 to spend at her grocery store. She is going to buy bags of fruit that cost $4.75 each and one box of crackers

Andrej [43]

First write the inequality: 15 $\leq$ 4.75x +3.50

Then to solve, first subtract 3.50 from both sides to get:

11.50 $\leq$ 4.75x

Then divide by 4.75 to get 2.42, and since you can't buy .42 of a bag of fruit, you round down. So your final answer would be 2 bags of fruit.

Write an equation that relates the angle in a triangle. The measure of angle A is 45 degrees. The measure of angle B is b degree

Korolek [52]

Since the interior angles of a triangle equal 180°, then 180-45=135.

Then you would use 135 to find the remaining two angles: b+3b=135.
4b=135.

Divide to find b. And the plug in whatever b is for the to figure out Angles B and C.

However, I believe the equation it's looking for is: 180=45+b+3b OR 45+4b=180

Current government spending to fund public schools is about 6×1011 dollars per year. The average cost nationally for a student t

NeX [460]

60000000 students can attend public schools with the current funding

Solution:

Given that Current government spending to fund public schools is about $6 \times 10^{11}$ dollars per year

The average cost nationally for a student to attend a public school for a year is about $10,000

To find: number of students can attend public schools with the current funding

$\text{ current funding } = 6 \times 10^{11} \text{ dollars}$

$\text{ average cost for 1 student } = 10000 \text{ dollars }$

Therefore,

$\text{ number of students } = \frac{\text{ current funding }}{\text{ average cost of 1 student}}$

Substituting the values we get,

$\text{ number of students } = \frac{6 \times 10^{11}}{10000}\\\\\rightarrow \frac{6 \times 10^{11}}{10000} = \frac{6 \times 10^{11}}{10^4}\\\\\rightarrow \frac{6 \times 10^{11}}{10^4} = 6 \times 10^{11-4} = 6 \times 10^7\\\\\rightarrow 6 \times 10^7 = 60000000$

Thus 60000000 students can attend public schools with the current funding
