Answer:
Step-by-step explanation:
This is a literal equation, and for some reason, students literally freak out about solving them. We will isolate h the same way we would if we were solving an equation for x. In order to get the term with the h in it all by itself, we have to move everything else away from that term. The 2πr² is added on the left, so we will move it by subtracting it from both sides, giving us
Then we need to get the h alone. Everything on the right side of the equals sign is multiplied together, so the "undoing" of multiplication is division, so that's what we'll do. Divide everything away from the h:
which is choice C.
Answer:
4/6
Step-by-step explanation:
I have showed the steps in the attached photo.
First, solve for each of the angles. Since it is a right triangle, one of the angles is 90 degrees. Knowing that the sum of the angles of a triangle are always equal to 180 degrees, you can write an equation for the triangle.
Angle1+ angle2+angle3=180.
Which means that 90+(x+15)+2x=180.
After finding the value of x, which is 25 in this case, solve for each angle.
X+15=25+15=40.
2x=25*2= 50
The value of the smallest angle is 40 degrees.
Answer:
The answer is -4.35
Step-by-step explanation:
3/8 = 0.375
x = 0.4
Now,
3/8x - 4.5
0.375 × 0.4 - 4.5
0.15 - 4.5 = -4.35
Thus, The answer is -4.35
