Answer:
No, it is not a right triangle.
Step-by-step explanation:
The simplest way to determine is testing out the numbers with Pythagorian theorem.
If it complies with the theorem, it is a right triangle.
let's assume c = 28, b = 21, and a = 20
the longest side is the hypotenuse so side c (28 in) will be the hypotenuse.
According to the Pythagorian theorem, the square of the length of hypotenuse must equal to the sum of squares of other two sides.
check:
c^2 = 28^2 = 784
a^2 + b^2 = 21^2 + 20^2 = 841
because c^2 is not equal to a^2 + b^2, the triangle is not a right triangle.
Answer: Mean(Mia)=34.33 Mean(Sophia)=35.667
Sophia's phone calls on average, are longer in length than Mia's phone calls.
Step-by-step explanation:
7 = 2x + 5
7 - 5 = 2x
2 = 2x
x = 1 ← <span>the other half of the coordinate</span>

Answer:
$ 9
Step-by-step explanation:
Simple Interest = P.R.T / 100
P = Principal (Amount invested) =$30
R = Rate= 10%
T = Time = 3 years
Therefore, Simple Interest (I):
I = PRT/100
I = ($30 * 10 * 3 ) / 100
I = $900 / 100
I = $9
She will have a total of $9 in three years
