Answer:
6553.6
Step-by-step explanation:
32^3 = 32 x 32 x 32 = 32768
32768 / 5 = 6553.6
Answer:
68 km
Step-by-step explanation:
A map has a scale of 4.5 inches = 36 km
We need to find the actual distance between the cities if the distance between two cities is 8.5 inches.
We can find 1 inch is equal to what as follows :
1 inch = (36/4.5) km
For 8.5 inches,
Hence, the actual distance between the cities is 68 km.
Answer:
Measure of DE is 12
Step-by-step explanation:
Here, we want to get the measure of DE
We have two similar triangles here
BDE and BAC
if two triangles are similar, then the ratio of their sides are same
Thus, in this case, we proceed as follows;
Now, since DE cuts each side into half;
we can have AB as 2y; then BD as y
Thus, we have that;
BD/DE = AB/AC
y/4x + 4 = 2y/x + 36
2y(4x + 4) = y(x + 36)
2(4x + 4) = x + 36
8x + 8 = x + 36
8x-x = 36-8
7x = 28
x = 28/7
x = 4
recall;
DE is 4x + 4
insert x = 2
DE = 4(2) + 4
DE = 12
