Answer:
72 pieces
Step-by-step explanation:
since 1/8 pieces would mean 8 per pie then
8*9 = 72
So 72 pieces
Answer:
B: 3
Step-by-step explanation:
For the line to be parrallel to the x-axis, it means the slope is zero.
Thus;
(y2 - y1)/(x2 - x1) = 0
(4k - 5 - (2k + 1))/(8 - 3) = 0
4k - 5 - 2k - 1 = 0
2k - 6 = 0
2k = 6
k = 6/2
k = 3
The population is increasing at the rate of 220
Explanation:
Given that the population of Hannah's town is increased from 1500 to 2600 in five years.
This can be written in expression as
and
![f(5)=2600](https://tex.z-dn.net/?f=f%285%29%3D2600)
We need to determine the rate of change of population.
The rate of change can be determined using the formula,
![\frac{f(b)-f(a)}{b-a}](https://tex.z-dn.net/?f=%5Cfrac%7Bf%28b%29-f%28a%29%7D%7Bb-a%7D)
where
and ![b=5](https://tex.z-dn.net/?f=b%3D5)
Substituting the values in the formula, we have,
![\frac{2600-1500}{5-0}](https://tex.z-dn.net/?f=%5Cfrac%7B2600-1500%7D%7B5-0%7D)
Simplifying, we have,
![\frac{1100}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B1100%7D%7B5%7D)
Dividing, we get,
220
Thus, the population is increasing at the rate of 220
(a+4)(a-3)
a^2 - 3a + 4a - 12
a^2 + a - 12
So the total number of students is 50, and you want to find 32/50. and that is equal to 64%
