Answer:
17.6
Step-by-step explanation:
22 x .80 =17.6
17.6 is 80% of 22 so that would be your answer
Awnser is D
You would do 464-232=232
Then divide 232/2=116
Answer:
The rate of dissolving depends on the surface area, temperature and amount of stirring.

Answer:
1,846.8
Step-by-step explanation:
76.95x2= 153.9
153.9x12= 1,846.8
Answer:
Option A
Step-by-step explanation:
We are given that
Scale factor=2
Center of dilation=(0,0)
Point A(0,2) and point B (2,0).
Slope of line f=![\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Substitute the values
Slope of line f=![\frac{0-2}{2-0}=-1](https://tex.z-dn.net/?f=%5Cfrac%7B0-2%7D%7B2-0%7D%3D-1)
Distance between A and Origin (0,0) is given by
![OA=\sqrt{(0-0)^2+(0-2)^2}=2 units](https://tex.z-dn.net/?f=OA%3D%5Csqrt%7B%280-0%29%5E2%2B%280-2%29%5E2%7D%3D2%20units)
Using distance formula
![\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D)
OB=![\sqrt{(0-2)^2+(0-0)^2}=2 units](https://tex.z-dn.net/?f=%5Csqrt%7B%280-2%29%5E2%2B%280-0%29%5E2%7D%3D2%20units)
Length of OA'=2OA=2(2)=4 units
Length of OB'=2(OB)=2(2)=4 units
x-intercept of line f' at x=4
y-intercept of line f' at y=4
Therefore, the points A' and B' are given by
(0,4) and (4,0)
Slope of line f'=![\frac{0-4}{4-0}=-1](https://tex.z-dn.net/?f=%5Cfrac%7B0-4%7D%7B4-0%7D%3D-1)
Slope of line f and f' are equal.Therefore, lines f and f' are parallel.
Option A is true.
