Answer:
D. He forgot to subtract the area of the base from the total surface area of the cube.
Step-by-step explanation:
He is only spray washing the *exterior* of the building; the base is not exposed so it will not be spray washed, which means Richard can use less water.
Hope this helps. :)
My answer to the question is as follows:
First one looks like you are squaring the number, then multiplying the result by 4, i.e.
<span>y=4<span>x2
</span></span><span>second one is similar, but instead of squaring and multiplying by 4, you are squaring and then dividing by 2
</span>
I hope my answer has come to your help. God bless and have a nice day ahead!
B. Y equals 0, because if you plug it in ( multiply 2 by 9 ) you will get 18-18 which equals 0.
Answer:
Step-by-step explanation:
b and c are the speeds of the boat in stool water, and current, respectively.
Going with the current, the boat travels b+c=16 km/h.
Going against the current, the boat travels b-c=6 km/h
add the equations together
b+c = 16
b-c = 6
—————
2b = 22
b = 11
c = 16-b = 5
