20 divided by 125
Answer:
see explanation
Step-by-step explanation:
The statements tells us that w is inversely proportional to v and the equation relating them is
v =
← k is the constant of proportion
To find k use the condition v = 9, w = 5, that is
9 =
( multiply both sides by 5 )
45 = k
v =
← equation of proportion
When w = 4 , then
v =
= 11.25
Answer:
470
Step-by-step explanation:
there are several surface areas.
1. the 4 side walls of the big block = 4*12*7 = 336
2. top and bottom of the big block = 2* 7*7 = 98
3. subtract the small rectangular area from the top area covered by the small block = 2*7 = 14
4. the 3 (visible) side walls of the small block on top =
3* 2*7 = 42
5. the small top and bottom areas of the small block =
2* 2*2 = 8
so, 1.+2.-3.+4.+5. = 470
Answer: $105.84
Step-by-step explanation:
20/100 = x/87.37
*cross multiply*
20*87.37 = 100x
1747.4 = 100x
*divide*
1747.4/100 = x
17.474
*add*
87.37 + 17.474
105.844
*round*
