8.5x + 9x = y
That is because you don't know how many hours they worked, so you can't how much money they made.
If you plugged in 4 hours for the x's you'll do something like this:
8.5 (4) + 9 (4) = y
34 + 36 = y
70 = y
That is how you would do it if you have the number of hours they worked.
Answer:
The third and fifth are correct
The second one is NOT correct
To get the area of the cone we need to find the radius first.
tan 70=r/12
r=12tan 70
area of a circle is given by:
A=πr²
thus the area of the ground covered by the tent will be:
A=π(12tan70)²
The answer is
A] A=π(12tan70°)²
Answer:
x = 9
Step-by-step explanation:
Both the triangles are similar, so the corresponding sides are also similar.
That is,
12 / 8 = x / 6
Cross multiply,
x * 8 = 12 * 6
8x = 72
Divide 8 on both sides,
x = 72 / 8
x = 9
