The side on the front of 30° is 1/2 of hypytenuse
Then 1/2 of 4=2 and the ather side with theorem of pytagore is squares root of(4^2-2^2)=sq .root of 12
This side(square root of 12) is 1/2 of hypotenuse then
Hypotenuse is 2*square root 12
X^2=(2*sq .root12)^2 -(square root 12)^2
X^2=48-12=36
X=6

Erin has written three tests for her math class. She calculates the average of hermarks on the first two tests. This average is

asambeis [7]

To obtain an overall average of 86%, a score of 96 is required on her 4th test.

Let the required score on her fourth test = t

The required average = 86%

Initial scores : 80% + 83.5% + 84.5%

Average = ΣX/ (fx)

fx = total score obtainable = 4 × 100 = 400

ΣX = sum of scores

Average = 86%

0.86 = ((80 + 83.5 + 84.5 + t) / 400)

86 = (248 + t) / 400

400 × 0.86 = 248 + t

344 = 248 + t

344 - 248 = t

96 = t

In other to obtain an overall average of 86%, she has to score 96 in her 4th test.

mixer [17]

Answer:

Step-by-step explanation:

Given that, .

Frederick make 7 × 7 quilt array

This shows that there are seven rows and there are seven columns.

So, the total quilt is

7 × 7 = 49 squares patches

We are told that each of this square patches are 3½ in long

Then, since it is a square patch, it's area is

A = S² = 3½ × 3½ = 12¼ in²

So, each square patch has an area of 12¼in²,

Then, for 49 square patches

The total area of 49 Square patches is

A = 49 × 12¼ = 600.25 in²

So, the area of the whole quilt is 600.25 in²
