Answer: OPTION A.
Step-by-step explanation:
First you must calculate the lenght of the side DF by applying the Pythagorean theorem, as following:

Now you can find sin(E) as you can see below:

Where:

Then:


Answer:
54.3
Step-by-step explanation:
4/3 x pi x 2.35^3
1. C.
The rule of powers is that when a parenthesis is raised to a power, you multiply the two numbers. Since it is being raised to the second power, it needs to have a 10 in the parenthesis. That would make 20.
2. B
Firstly 10^2 = 100, so we know that the number must be 10. That leaves us with just A and B. Then we know the same thing from the previous equation, that they need to be multiplied together.
Answer:
x can be cancelled
Step-by-step explanation:
we are given

Firstly, we will factor numerator and denominator
and then we can factor it


now, we can factor denominator


now, we can replace it

we can see that
both terms are having x common
so, x can be cancelled
So,
x can be cancelled
Volume = (Area of the base)x(Height)
66.85 = 15(H)
66.85/15 = H
H = 4.4567
The height is 4.4567mm.
