The formula for the atrapezoid is Ah bi b2). Express bi in number of feet inarea of terms the of a trapezoid is 60 square feet, its height is 6 ft, and one base is 12 Find other base.

Answers

Answer 1

Answer: Area = 1/2h(b1 + b2)

60 = 1/2(6)(b1 +12)
60 = 3(b1 +12)
60 = 3b1 + 36
24 = 3b1
24/3 = b1

b1 = 8

The other base is 8 feet

128 is what percent of 640

Answers

The number 128 is 20 percent of 640.

What is percentage?

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means.

Let 128 is x percent of 640.

Here, x% of 640 =128

x/100 ×640 =128

6.4x=128

x=128/6.4

x=20%

Therefore, the number 128 is 20 percent of 640.

↑ 128 is 20% of 640
Lets solve:
640 IS 100% Because its the output value of the task
So lets look for x
We got 100%=640
and x%=128
Now im going to write this out as
100% / x%=640/128
Now we just have to solve this simple equation.
(100/x)*x=(640/128)*x
-Multiply both sides of the equation by x
Now we divide both sides of the equation by 5 to get x.
100=5x
100/5=x
20=x
and
x=20
So we got our answer of 20%

Answers

In the given question, there are several information's of immense importance. using these information's the correct and the required answer can be determined. It is given that an unknown number has to be found from the information's provided.
Let us assume the unknown number = x
Then
3x + 3 = 2x -1
3x - 2x = -1 -3
x = -4
So the unknown number is -4.
It should be remembered that these are trick questions and it is important to go through each lines very carefully to understand the inner meaning.

Let's say the unknown number = x

Now we have to set up an equation in order to solve for x.
3x + 3 = 2x -1
x = -4

Your answer should be -4
