Answer: 23.25m
Step-by-step explanation:
C=2πr=2·π·3.7≈23.24779m
Answer:
20 cm
Step-by-step explanation:
Shadow of vertical poles : 6m ; 15m
Length of poles : 8cm ; h
8cm long pole = shadow length, 6m
h cm long pole = shadow length, 15 m
Using cross multiplication :
8cm * 15 m = h cm * 6m
120 = 6h
h = 120 / 6
h = 20 cm
Height of second pole = 20cm
First, put it into point-slope form.
Find the slope:
m=(y2-y1)/(x2-x1)
m=(-6-(-2)/(2-1)
m=(-6+2)/1
m=-4/1
m=-4
Now, put it into point-slope:
y-y1=m(x-x1)
y-2=-4(x-(-6)
y-2=-4(x+6)
y-2=-4x-24
Slope intercept form: y= mx+b
Add 2 to the other side.
y=-4x-22 <== the answer
I hope this helps!

Answer:
i think its 96 dollars
Step-by-step explanation:
600 × .06 = 24
24 × 4 = 96
The key term here is inverse variation - that is, two or more variables must multiply to a certain product.
So, let's multiply 12 and 8. We get 96.
The correct pair must contain factors of 96.
16 and 6 are factors of 96, so the answer is (D).
