Answer:
11,448 in²
Step-by-step explanation:
The area can be computed from ...
... A = 2(LW +H(L+W))
For the given prism, the area will be ...
... A = 2(18·12 +14(18+12)) = 2(216 +420) = 1272 . . . . in²
The area of a similar figure with dimensions 3 times as long will be 3² times as much. The area of the new figure is ...
... A = 3²×(1272 in²) = 11,448 in²
Answer:
-14
Step-by-step explanation:
2c + d
We are given the values of c and d:
c = -9
d = 4
We substitute in these values
2(-9) + 4 = ?
2 times -9 is -18
-18 + 4 = -14
2c + d = -14
The correct scale factor is 3 :)
So 1/8 as a percentage is 12.5%.
80% is greater than 12/5%.
So your answer would be 80%.
Answer:
A) each donut costs $0.65
B) the price for 1 and 1/2 dozen of donuts (18 donuts) is $11.70
Step-by-step explanation:
For a you have to divide $7.80 by 12 (since its a dozen) and thats how you get $0.65
For b you have to multiply the price of each donut ($0.65) by the 1 and 1/2 dozen (18 donuts) and thats how you get $11.70
