Answer:
the fraction of surface that is not covered is 11/36
Step-by-step explanation:
To do this we first have to calculate the two surfaces
s = π * r^2
π = 3.14
r = d/2
d1 = 20
d2 = 24
r1 = 20/2
r1 = 10
r2 = 24/2
r2 = 12
s1 = π * r1^2
s1 = 3.14 * 10^2
s1 = 3.14 * 100
s1 = 314
s2 = π * r2^2
s2 = 3.14 * 12^2
s2 = 3.14 * 144
s2 = 452.16
to know the part that is not covered we simply do the s1 over the s2 and we subtract that from 1
s1 / s2 =
314 / 452.16 =
25/36
1 we subtract this
1 - 25/36 = 11/36
the fraction of surface that is not covered is 11/36
Answer:
295 SUVs were sold, and 215 passenger vehicles.
Step-by-step explanation:
Let s and p represent the number of SUVs and p the number of passenger cars.
Then s = p + 80 and s + p = 510.
Substitute p + 80 for s in the second equation, obtaining:
p + 80 + p = 510, or:
2p = 430
Dividing both sides by 2 isolates p: p = 215.
Since s = p + 80, we add 80 to 215 here, obtaining s = 295.
295 SUVs were sold, and 215 passenger vehicles.
Answer:
3
Step-by-step explanation:
Subsitute -4 for m and 2 for p as given
( 4(2) - (-4) ) / 4
Double negatives make a positive.
( 4(2) + 4 ) / 4
Multiply inside parenthesis first
( 8 + 4 ) / 4
Add
12 / 4
