Answer:
33% discount
Step-by-step explanation:
15$ is the amount that was taken off so now we just need to convert it to a % of 45
45/100 = 30/?
if you do cross multiplication and multiply 30 * 100 then divide the result (3000) by 45 you get 66
This means that 30$ is 66% of 45. To find the discount you just subtract 66% (this represents your 30$ new price) from 100% (this represents the 45% original price) and you get 33%.
Answer:
x = 180 - 32 - 43 - 72 = 33°
Answer:
This is very easy. First find the volume of the cube, and then add it to the volume of the hemisphere to find the total volume.
The volume of the cube is length x width x height: 8 x 8 x 12 = 768 cm
The volume of the hemisphere is (2/3)πr³ : (2/3)π(4)³ = 134.04 cm
*Radius is 4
Now add: 768 + 134.04 = 902.04 cm
