A trapezoid doesn't have any square corners
Answer:
From the Pythagorean theorem...
[ distance between (a, 7) and (2, 1) ]2 = [a - 2]2 + [7 - 1]2
And they tell us that the distance equals 3√5 , so
[ 3√5 ]2 = [a - 2]2 + [7 - 1]2
45 = [a - 2]2 + 36
9 = [a - 2]2
±√9 = a - 2
± 3 = a - 2
± 3 + 2 = a
a = 3 + 2 = 5 or a = -3 + 2 = -1
and
5 + -1 = 4

Answer:
2 of these numbers are divisible by 4 and 5.
20 and 60 are divisible by 4 and 5.
Step-by-step explanation:
20 is divisible by 4 and 5.
Divisible just means that the 4 (also the 5) goes into 20 evenly, with no remainder.
4 goes into 20 evenly with no remainder.
5 goes into 20 evenly with no remainder.
4 does not go into 35 evenly with no remainder.
35 ÷ 4 is 8 with a remainder of 3.
35 ÷ 4 = 8.75
5 does go into 35. 35 is divisible by 5.
35 is not divisible by 4.
60 is divisible by 4
60 ÷ 4 = 15 (no remainder, no extra decimals if you do it on a calculator)
60 ÷ 5 = 12 (no remainder, no extra decimals if you do it on a calculator)
60 is divisible by 4 and also by 5.
Answer:
58%
Step-by-step explanation:
vertical angles are always the same
The equation is:
y = 10 sin(π/15 t) + 30
where 30 represents the initial height of the blade above the ground and π/15 represents the period as we are given that the blade completes two rotation every minute.Finally the 10 represents the length of the blades.
