So to set this problem up lets understand it.
each percent is out of a whole (100%)
so the whole in this problem is 450 pounds
and to make 44% a usable number we move the percent sign two places over.
.44
to find out how many times .44 goes into 450 pounds we will multiply
(.44×450)=198 pounds
we can check our answer by dividing 198÷450
and getting .44 as our answer
9514 1404 393
Answer:
100(π+3) ≈ 614 square units
Step-by-step explanation:
Assuming the rectangles are squares, the total area is that of 3 squares and a circle of radius 10.
circle area = πr² = π·10² = 100π
area of squares = 3×s² = 3·10² = 300
Then the total area is ...
300 +100π ≈ 614 . . . square units
Answer:
The equation represents exponential growth
Step-by-step explanation:
Since the equation is a positive exponential equation
You know that t=0 and x=0, the car starts moving with a constant acceleration of 2.70m/s²
At the same time, a truck moving speed o 8.50 m/s passes the car
D=v.t (for the truck)
And d= v.t+1/2.a.t²(for the car)
v.t=1/2.a.t²
t=2.v/a
t=2.8.50 m/s/ 2.70 m/s²
17m/2.70=6.29
This mean that the distance is
D=v.t=8.50m/s.6.29= 53.465 m/s
The speed of the car is
Vcar=a.t
2.7m/s2×× 53.65
=144.34
