Hi there!
"mph" stands for "miles per hour".
This means that the car travels 55 miles in 1 hour.
To find your answer, you'll need to use the cross product method :
55 miles → 1 hour
206.35 → x
(1 × 206.35) ÷ 55 = x
206.35 ÷ 55 = x
206.35 ÷ 55 = 3.751818...
206.35 ÷ 55 ≈ 3.75
0.75 × 60 = 45 minutes
Your answer is: It takes 3 hours and 45 minutes for the car to arrive at its destination.
There you go! I really hope this helped, if there's anything just let me know! :)
Answer:
the initial height of ball when the player releases it
Step-by-step explanation:
A basketball player shoots a free throw in a game. The quadratic expression models the height of the ball, in feet, where t is the time, in seconds.
y= -16t^2 + 25t+7
Given equation is in the form of
y= -16x^2 + V t + h
Where V represents the initial velocity and h represents the initial height of the ball
Now we compare our equation with the general equation
We have 7 in the place of h
So , 7 is the initial height of the ball
Answer is 7 is the initial height of ball when the player releases it
Answer:
Step-by-step explanation:
It’s a cube with edge length of 12 cm.
The cube has six faces, and the are ma if each face is 144 cm²
Total surface area = 6×144 = 864 cm²
Answer:
0.783
Step-by-step explanation:
To find first r and then r square for the data
correlation coefficient of x and y = Cov (x,y)/std dev x * std dev Y
Cov (x,y) = E(xy) -E(x)E(y)
Hence calculations would be as follows:
x y xy
1 2 2
2 10 20
5 5 25
7 18 126
10 25 250
Mean 5 12 84.6
Cov E(xy)-E(x)E(y) 24.6
r 0.884640297
r^2 0.782588454
so answre is 0.783 after rounding off.
