Round up if this number is greater than or equal to
5
and round down if it is less than
5
122
Hope I helped
The formula to solve for this would be pi(r^2)xheight. Essentially what this formula does is it takes the are of the base (pi x r^2) and multiplies it by the height of the cylinder to find how many times the base can stack on itself until it reaches the top. This formula of base are times height works for all prisms with two bases. Here are the steps to solve:
1) plug in the values
- pi(15^2) x 45
2) solve for the base area of one of the circles
- pi(15^2)=225pi
3) multiply the base area by the height
- 225pi x 45 = 10,125pi
4) final answer: the tank can hold 10,125pi cubic feet of water
C)-2/3is the answer because when your have 2/3+-2/3 will equal 0 in which justifies the additive inverse
Answer:
5, -⅓
Step-by-step explanation:
x = 2:
4x + 3y = 23
3y = 23 - 4(2)
3y = 15
y = 5
x = 6:
4x + 3y = 23
3y = 23 - 4(6)
3y = -1
y = -⅓
The goal in simplifying numbers
is to reduce it that can be best seen in the eye. In here, you are given 5a x 2c x
3d. Note that 5, 2 and 3 are coefficients and a, c and d, are variables. Multiply first
the coefficients 5, 2 and 3 and you get 30. Always remember that in multiplying
numbers, especially variables, the base of the exponent must be equal. However,
you have variables of a, c and, d. You cannot multiply or add them because they
are different. So the answer is 30acd.
