16 36 169 100
Step-by-step explanation:
just square them
Answer:
Part A= 36% I got my answer by subtracting the part from the total.
Part B= The total number of sixth graders on academic teams is 124. I got this by adding the 45% and the 36% to get 81% and then add the total number of students in both schools, which was 124. So then 81% of 155 is 124.
Step-by-step explanation:
100% - 64% = 36%
_____________________
45% + 36% = 81%
80 + 75 = 155
80% of 155 is 124
7.48 pounds are equal to approximately 3.39 kilograms.
Answer:
x = 4 sqrt(5)
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
8^2 + x^2 = 12^2
64+ x^2 =144
Subtract 64 from each side
x^2 = 144-64
x^2 =80
Take the square root of each side
sqrt(x^2) = sqrt(80)
x = sqrt(16*5)
x = 4 sqrt(5)
