A) To cook 1/2 cup of rice, the package tells you that you also need 1 cup of water. The the total volume of ingredients is
.. 1/2 c + 1 c = 1 1/2 c
b) According to the package the ratio of water to rice is
.. water : rice = 1 : 1/2 = 2 : 1
Then the ratio of water to total ingredients is
.. water : (water + rice) = 2 : (2 +1) = 2 : 3
Susan's ratio is incorrect. Susan is using "1" for the total of ingredients, instead of 2+1 = 3. The correct ratio is 2:3.
The ratio of the height (h) of the streetlight to its distance to the end of Laura's shadow is the same as the ratio of Laura's height to her distance from the end of her shadow.
.. h/(12+9) = 5'4"/9
.. h = (21/9)*5'4" = 12 4/9 feet
.. h = 12 ft 5 1/3 inches
The streetlight is 12 ft 5 1/3 inches tall.
Answer:
-1/2
Step-by-step explanation:
-1/2 is the slope and -7 is the y intercept.
The inverse of this would be
Answer:
D) 168 ft3
Step-by-step explanation:
The formula to find the volume of a cone is V=π
.
We need to plug in the radius, 4, and the height, 10, into this equation.
V=π
V=π16
V=π53.33
V=167.55
If we round up to the nearest whole number, we get 168 
. Therefore, the correct answer is D) 168 ft3.
I hope I helped!
