Answer:
12 in.
Step-by-step explanation:
Formula: a^2 + b^2 = c^2
This case: c^2 - a^2 = b^2
1) 15^2 + 9^2 = b^2
2) 225 - 81 = 144
3)
= 12
Whats the rest of the question? a+5=???????????
Answer:
2
Step-by-step explanation:
Answer:
Step-by-step explanation:
1) 3 x 20 = 60 (that how much she give)
2) 60- 57.32 = 2.68 (that the change they will split up)
3) 2.68/2=1.34 ( they will each get $1.34)
Answer:
h(x) = (1/4)x - 2 which is choice A
Step-by-step explanation:
Replace f(x) with y. Then swap x and y. Lastly, solve for y to get the inverse.
f(x) = 4x+8
y = 4x+8
x = 4y+8
x-8 = 4y
4y = x-8
y = (x-8)/4
y = x/4 - 8/4
y = (1/4)x - 2
h(x) = (1/4)x - 2
