Answer:
20
Step-by-step explanation:
<u>Given:</u>
<u>As per the picture:</u>
- m∠JKL = m∠JKM + m∠MKL = 45 + x
<u>Comparing the two equations above:</u>
- 3x+5 = 45 + x
- 3x - x = 45 - 5
- 2x = 40
- x = 40/2
- x = 20
x = 20 is the correct answer for this question
Otherwise something is wrong with the question.
Whatever your answer was, you should be able to simply place two zero's behind it
The easiest method of multiplying polynomials, in my experience, is the FOIL method. Honestly, I couldn't tell you what the letters stand for anymore, but I definitely remember how to do it. It's just distribution.
(6x+1)(5x+8)
Multiply the 6x by 5x and 8, then the 1 by 5x and 8:
30x²+48x+5x+8
Then combine like terms:
30x²+53x+8
Answer:
Amie should have multiplied 54 by 2/3
Step-by-step explanation:
The formula of the volume of a sphere is given by
, where r is the radius of the sphere.
to find the volume of the sphere, we must find
We know that the formula of a cylinder of height h and radius r is given by
So
We know that the sphere and the cylinder have the same height. Recall that the height of the sphere of radius r, is the diameter of a circle that passes through the heighest and lowest points of the sphere. Then, h=2r. This means that
From here, we know that .
So the volume of the sphere is .
So Amie should have multiplied 54 by 2/3.
