A^2 + b^2 = c^2
a^2 + 15^2 = 17^2
a^2 + 225 = 289
a^2 = 289 - 225
a^2 = 64
a = sqrt 64
a = 8 cm
Answer: Student X and Y
Step-by-step explanation:
Student W started off correctly as they simplified the first expression and got rid of the parentheses.
Student Z also started off correctly as they simplified the second expression and combined the like terms.

Answer:
the percentage is 12%
Step-by-step explanation:
Given that
The 12 students picked up the vanilla cupcake
And, 88 students picked up the chocolate cupcake
We need to find out the percentage of the students picked up a vanilla cupcake
So, the percenatge is
= (12) ÷ (12 + 88) × 100
= 12 ÷ 100 × 100
= 12%
Hence, the percentage is 12%
Answer:
C
Step-by-step explanation:
If a line bisects a segment, both sides of the segment are equal. Therefore, IJ and JK have the same length, and are equal.
V=1/3(π)r^2(h)
v=1/3(3.14)(7^2)60
v=1/3(3.14)(49)(60)
v=1/3(9,231.6)
v=9,231.6÷3
v= 3,077.2
