[tex]16(2)+4 = 36ft[/tex]

[tex]Perimeter = 36ft[/tex]

Question 2:

[tex]P = 4(3x-15)=12x-60[/tex]

[tex]P = 12(25)-60=240cm[/tex]

What is the value of b. If A+B=C and A=35 and C=25
Explain how you got this answer

Answers

Answer:

[tex]B=-10[/tex]

Step-by-step explanation:

Hi!

So let's write the equation again

[tex]A+B=C[/tex]

The next step is to plug in known values:

[tex]35+B=25[/tex]

Now we solve this as a normal algebra equation:

Do same to both sides

[tex]B = 25-35[/tex]

[tex]B=-10[/tex]

I hope this helped. Let me know if you have any questions

The answer is -10. No positive number could equal 25 and if 35-25 is 10, it would only make sense to be negative. Say if you have $25 but you need 35, you’d be in debt of $10 you borrowed from someone else. Hope this makes sense, I’m not the best at explaining.

Answer:

The answer is 0.045

Step-by-step explanation:

1. Use this formula V=lwh

0.5 x 0.4 x 0.15 = 0.03

That is the volume of the lower prism

2. Do V=lwh again for the volume of the upper prism

0.5 x 0.15 x 0.2 = 0.015

3. After that add both of them up together

0.015 + 0.03 = 0.045

Find the percent of change from 6,570 pt to 16,425 pt.

Answers

Answer:

Percentage Change | Increase and Decrease

First: work out the difference (increase) between the two numbers you are comparing.

Increase = New Number - Original Number.

Then: divide the increase by the original number and multiply the answer by 100.

% increase = Increase ÷ Original Number × 100.

Step-by-step explanation:

hopefully this helped and you can find the percent change.

I think you would do
6,570 divided by 16,425
And that would get you
0.4%

The answer is D. I’m assuming this is surface area so here’s my explanation:) ok so the area of the triangle is 6 (4x3 divided by 2) and when you add the other triangle that’s 12. Ok so we have 12 so far. Then the area of the bottom rectangle is 24 (3x8). Then the area of the side rectangle is 32 (4x8). THEN the top rectangle’s area is 40 (8x5). When you add the numbers up (12+24+32+40) you get 108! And of course dont forget the cm2. ( centimeters squared ). :) I hope this helps

Explain how to solve the equation and how to check the solution.
40 = 8y

there the answers-
Use the inverse operation to isolate the variable. Undo multiplication by dividing by 8 on both sides of the equation. Simplify by completing the divisions, 40 ÷ 8 = 5, and 8 ÷ 8 = 1. The solution is y = 5. Check the solution by substituting 5 for y in the original equation, and then simplify. 8 × 5 = 40 and 40 = 40 is a true statement, so 5 is the solution.

Step-by-step explanation:

Paul makes a base monthly salary of $1500. As a vendor, he must sell $19000 worth of items per month. He also makes a 6% commission on all sales beyond the monthly quota. If Paul sold $26600 worth of items this month, what is his total salary for the month including base salary and commission to the nearest dollar?

Answers

Answer:

salary=$1500

sell =$19000

commission =6%

he sells of $26600

commission amount =6% of[26600-19000]=$456

total salary =$1500+456=$1956 is the required salary.

The total salary for the month including base salary and commission to the nearest dollar is $1956.

It is required to find total salary for the month.

What is arithmetic?

The branch of mathematics dealing with the properties and manipulation of numbers. a science that deals with the addition, subtraction, multiplication, and division of numbers. Fractions, decimals, percentages, fractions, square root, exponents, and other arithmetic operations are used to achieve mathematical simplifications

Given that:

salary=$1500

sell =$19000

commission =6%

he sells of $26600

6% Commission for every sales beyond the quota commission amount =6% of[26600-19000]=$456

Base Salary + 6% Commission,

∴Total salary =$1500+456=$1956 is the required salary.

Here, the total salary for the month including base salary and commission to the nearest dollar is $1956.

A car has 15 gallons of gas in its tank. The car travels 35 miles per gallon of gas. It uses 135 of a gallon of gas to go 1 mile.

1. How far can the car travel with 15 gallons?

Answers

Answer:

525 miles

Step-by-step explanation:

Two unit rates are given in this problem:

miles per gallongallons per mile

Since we want to find miles, the appropriate rate to use is miles per gallon:

distance = mile/gallon x gallons

distance =35 miles/gallon x 15 gallons = 525 milles

The car can travel 525 miles on 15 gallons of gas.
