Answer: 548.8 square inches
Step-by-step explanation:
From the question, we are informed that a cereal box has a surface area of 280 square inches.
The surface area of a similar box that is larger by a scale factor of 1.4 will be gotten by multiplying 280 by the scale factor's square. This will be:
= 280 × (1.4)²
= 280 × 1.96
= 548.8 square inches
Hi there
The formula is
A=p (1-r)^t
A future value?
P present value 12050
R rate of decreases 0.12
T time 9 years
A=12,050×(1−0.12)^(9)
A=3,813.6 round your answer
A=3814
Hope it helps
Notice that the two semicircles have a radius of 10/2=5 and that their area is simply the area of a complete circle with a radius of 5. In the center you have a rectangle that is 10 by 8. So the total area is:
A=pr^2+xy
A=25p+80 m^2
A≈158.53 which is:
A≈158.5 m^2 (to the nearest tenth of a m^2)
60/100=0.6
0.6x32=19.2
0.6x50=30
30-19.2=10.8
The answer is 10.8 grams of sugar must be added to obtain a solution that is 50% sugar
