Answer:
8r.
Step-by-step explanation:
If we substitute 3 into all of these equations, we get
8(3) which equals 24
6(3) which equals 18
9(3) which equals 27
7(3) which equals 21
8r is the one that equals 24 when 3 is substituted.
Answer:
Step-by-step explanation:
Given that,
The radius of circle, r = 7 cm
The area of sector, A = 44cm²
We need to find the angle of the sector. The formula for the area of sector is given by :
Solve for 
.
So, the angle of the sector is equal to 
.
Answer:
I think the answer (-2, 6)
Since distance equals speed times time (d = st), we have
t = d/s
where d = 120 miles and s = 15 miles per hour
t = d / s
t = 120 / 15
t = 8
It will take 8 hours to drive 120 miles at a speed of 15 miles per hour.
Answer:
Step-by-step explanation:
the expression could help you find the distance between A(x; y) and B(x',y')is:
AB = √((x-x')²+(y-y')²)
in this exercise : x = 10
x' = - 6
y =4
y' = 4
