A square is cut in half on the diagonal creating two equal triangle. Each triangle has an are of 1.32 square units. What is the side length in unit of the orginial square

Answers

Answer 1

Answer: What is the side length in unit of the original square?

Let's start by getting the area of the square.
The area of the square is the sum of the areas of the two triangles, or
2 x 1,32 = 2.64 square units.
Now, all sides of a square are the same length. That is the length we need, let's call that length L.
So, the area of the square is L x L = 2.64 square units, which is the same as the square root of 2.64

Find a measure of angle 8.

Answers

Angle 7 and 5 are vertical angles, so they're equal. Angles 7 and 8 are supplementary, so they have to add up to 180. 2x + 15 + 3x = 180 Solve for x, then plug it into the expression for angle 7 to get you answer

A city's sales tax is 0.07 write this decimal as a fraction and tell how many cents of tax are on each dollar

Answers

we know that

To convert the decimal as fraction in this problem, multiply and divide by one hundred

$0.07=0.07*(100)/(100)=(0.07*100)/(100)=(7)/(100)$

therefore

the answer Part a) is

the decimal as fraction is equal to $(7)/(100)$

Part b)

we know that

$1$ dollar is equal to $100$ cents

$1$ cent is equal to $0.01$ dollars

the tax is equal to $0.07$ dollars

by proportion

$(100)/(1) (cents)/(dollar)=(x)/(0.07) (cents)/(dollars)\n \nx=100*0.7\n \nx=7\ cents$

the tax is equal to $7$ cents

therefore

the answer part b) is

There are $7$ cents of tax in each dollar

as a fraction it is 7/100 and it would be 7 cents for each dollar. it is $1x.07

Answer:

The rate change is 3, and it is a linear model.

Step-by-step explanation:

Andre continuously puts in $3 each week, don't be confused by the skipping numbers, and it's linear because the line would continuously climb up in a straight line.

Answer:

The rate of change varies. It is a non-liner model.

This is what I'm thinking because the answers on each do not have the same distance away from each other.

The problem here is: Too many words.

If you boil the problem down to the bare facts, the question is:

   "$210 is 15% of what number ?"

I'm pretty sure you can take it from there,
but here's the rest of it anyway:

$210 = 15% of (March amount)

      $210 = 0.15 x (March amount)

Divide each side by 0.15 :   $1400 = March amount .

Check:
1400 + 210 = 1610
1.15 x 1400 = 1610 yay!
