Answer:

102 1/2 feet

Step-by-step explanation:

assuming that the perimeter is a rectangle, you add 30 3/4 + 30 3/4, which are two sides, and 20 1/2 + 20 1/2, which are the other two sides, and when you add the sums of those two equations together, you get the perimeter, therefore, the answer is the perimeter, 102 1/2 feet.

Alla [95]

Answer:

$v = \frac{4}{3} \pi {r}^{3 } \\ 904.32 = \frac{4}{3} \times 3.14 \times {r}^{3} \\ {r}^{3} = \frac{3 \times 904.32}{4 \times 3.14} = 21.57 \\ r = 2.78$

A sandwich store charges a delivery fee to bring lunch to an office building. One office pays $33 for 4 turkey sandwiches. Anoth

shutvik [7]

Answer:

$12

Step-by-step explanation:

assuming that the cost of delivery is constant irrespective of the number ordered

Let the cost of sandwich be x

First office

$33=4x+c where c is the cost of delivery

Second office

$61=8x+c

These two are simultaneous equation. Subtracting the equation of first office from the second office we obtain

4x=28

Therefore, x=28/4=7

The cost of delivery is 33-(4*7)=33-28=5

Therefore, one sandwich plus delivery costs 7+5=$12
