Answer:
Answer is 81y^4z^4
Step-by-step explanation:
The expression is (-3yz) (-3yz) (-3yz) (-3yz).
Since all the four terms have power 1:
(-3yz)^1 (-3yz)^1 (-3yz)^1 (-3yz)^1
We know that we can add the powers if the terms have same base
So,
=(-3yz)^1+1+1+1
=(-3yz)^4
=(-3)^4(y)^4(z)^4.
If the power is an even number than the negative sign changes into positive sign.
=3^4y^4z^4
=81y^4z^4
Thus the answer is 81y^4z^4....
Answer:
92.5%
Step-by-step explanation:
shaded squares/total squares = 185/200
simplify:
(185/5)/(200/5) = 37/40
37/40= 35/40 + 2/40
32/40 + 5/40 = 4/5 + 1/8
4/5 + 1/8 = 0.8 + 0.125
0.8 + 0.125 = 80% + 12.5%
80% + 12.5% = 92.5%
Oh okie so I Pepeooooo oit the way
305-35=270 (SA of 3 triangular faces)
270/3=90 (area of one face)
A=.5BH
90=.5(9)H
90=4.5H
H=20 in
