Answer:I need to score between 75 and 100 to get a B.
Step-by-step explanation:
To get the number I must score in the 5TH Test, the total of the first four test is added together
68+82+87+89 = 326
However making the number I must score X
There is need to find a new average
And the total number of score is now equal to 5, so we generate the equation.
(326 + X)/5=80
326+X= 400
X= 400-326
X= 74
However he needs to score equal or above 74 and 100 to get a B.

The sides of right triangle are related based on Pythagorean Theorem.
Step-by-step explanation:
Given that,
Side 1 = s1 = 15cm
Side 2 = s2 = 20cm
Side 3 = s3 = 25cm
The general definition of Pythagorean Theorem is that the square of hypotenuse is equal to the sum of square of other two sides in right triangle.
Also, hypotenuse is the largest side of rectangle. So, it is 25 cm.
In that case, the Pythagorean Theorem would be:
625 = 400 + 225
625 = 625
Hence, the sides of right triangle are related based on Pythagorean Theorem.
