Let’s say the original fraction is 100/100 (this is 100%) and we decrease what the question tells us to, we then get a fraction of 15/75.

15/75 is equal to 20%.

-100- 20= 80%
The ratio of his savings: expenses = 7: 5
So, total of the ratio is = 7 +5 =12
His savings will be 7/12* allowance
His expenses will be 5/12 * allowance
We know that the allowance that he gets is $3
His savings = 7/12 * allowances
His savings = 7/12 * 3
His savings = $7/4 or 1 ¾
Now, we convert the 7/4 (or 1 ¾) into a decimal.
1 ¾ when converted is decimal is 1.75
His Savings = $1.75
Let's start with the length. All you need to do is multiply is by 1/500.
You could also find the decimal equivalent to 1/500.
1/500= .002
200×.002= .4
So length of the model is .4 ft.
The width:
.002×140=.28
The width of the model is .28 ft.
The length of the model is .4 ft and the width of the model is .28 ft.
Answer:

Step-by-step explanation:
Notice that A, B, and C constitute the vertices of a right angle triangle, with the right angle at the vertex A.
If we count the number of squares separating B and A (one of the legs of the right angle triangle) we find 8 units.
If we count the number of squares separating C from A (the other leg of the right angle triangle), we get: 3 units.
Then, we apply the Pythagorean theorem to find that length of the triangle's hypotenuse which is the segment BC:

Below is the proof why the area of a parallelogram is B times H
<h3>How to form a rectangle from the parallelogram</h3>
The following steps would create a rectangle from the parallelogram
- Step 1: Cut out the triangular part of the parallelogram
- Step 2: Attach the triangular part to the other end of the parallelogram
See attachment for the steps.
When the rectangle has been created, we have the following dimensions:
Length = h
Width = B
The area of a rectangle is:
Area = Length * Width
This gives
Area = h * B
Evaluate
Area = Bh
Hence, the area of a parallelogram is B times H
