Which expressions represent the volume of the composite figure (the shaded figure)? check all that apply.
(7)(12)(10) – π(32)(10)
1/3(7)(12)(10) – π(32)(10)
1/3(7)(12)(10) + π(32)(10)
280 – 30π
280 + 30π
840 – 90π

answer:

b. 1/3(7)(12)(10) –1/3 π(32)(10)

d. 280 – 30π

step-by-step explanation:

answer:

the answers are b and d

step-by-step explanation:

just took the class

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
