20 miles a gallon? 120 divided by 6
Answer:
7.7 ft
Step-by-step explanation:
The third longest side is also the second shortest side.
The 14 ft side of quadrilateral ABCD corresponds to the 6 ft side of quadrilateral EFGH.
14/6 = 18/x
7/3 = 18/x
7x = 18 * 3
7x = 54
x = 54/7
x = 7.7
Answer: D. 7.7 feet
Answer:
100π
Step-by-step explanation:
The equation of the circumference of a circle is C=2πr.
So to get an answer that not rounded you would keep the π and multiply 50 by 2= 100
sub x=1, a(1)^2 +b(1) + c=0,
a+b+c=0______eqn 1
sub x=-1, a(-1)^2+b(-1)+c=2
a-b+c=2_______eqn 2
sub x=2, a(2)^2+b(2)+c=8
4a+2b+c=8______eqn 3
from eqn 1
c=-a-b
eqn2
a-b-a-b=2
-2b=2
b=-1
eqn3
4a + 2b -a-b=8
3a+b=8
3a+(-1)=8
3a-1=8
3a=9
a=3
c=-a-b
c=-3--1
c=-2
Percent increase is new amount-original amount divided by original amount
75-40=35
35/40=.875
87.5%
