Answer:
1.4222222222
Step-by-step explanation:
If the ratio is 4:3 divide the larger can by 4 which in a) is 25 then multiply by 3 to get surface area of smaller can which would be 75 square inches.
In part b) do the same so 150 divided by 4 is 37.5 multiplied by 3 is 112.5 cubic inches.
It doesn't matter if it is surface area or volume you still use the same ratio of 4:3
Answer:
she worked 9 hours at sporting goods store and 6 hours on piano lessons.
Step-by-step explanation:
total hours=15
8.47x + 17(15-x) = 178.23
8.47x + 225 - 17x = 178.23
225 - 178.23 = 17x - 8.47x
76.77 = 8.53x
x = 76.77 / 8.53
x = 9
therefore she worked 9 hours at sporting goods centre and the remaining hours (15-9) giving piano lessons.
