Answer:
The wheels make 512 revolutions per minute
Step-by-step explanation:
Diameter of truck = 36 in
Speed = 55 mi/h
Revolutions per minute =?
Radius r = diameter / 2
r = 36/2
r = 18 inches
Speed = 55 mi/h
1 mile = 63360 inches
55 miles = 55*63360 inches
55 miles = 3484800 inches
1 hr = 60 minutes
Speed = 3484800 inches/60 minutes
Speed = 58,080 inches/min
The formula used to calculate the revolutions per minute is:
revolutions = speed/Circumference
revolutions = 58,080 / 2*3.14*18
revolutions = 58,080 /113.4
revolutions = 512.16
revolutions = 512 revolutions per minute
So, The wheels make 512 revolutions per minute
F(5)=2 you look at the x-axis and find 5 which is in the right side then find the point on the line that touches and you will see it’s 2.
Idk, think its 1.53 of the pizza
Answer:
0.499662
Step-by-step explanation:
Now since 51.3% of all babies are boys, this means that the probability of having a baby boy P(b) = 51.3/100 = 0.513
Since there are only two options, you are either a boy or a girl. The Probability of having a girl child P(g) = 1 - P (b) = 1 - 0.513 = 0.487
Now, we proceed to calculate the probability.
The probability of having one boy and one girl = probability of one boy and one girl or probability of one girl and one boy
Or in probability means that we have to add the two possibilities together.
P = (0.513*0.487) + (0.487 * 0.513) = 0.499662
Base is 4 units
height is 6 units
6 x 4 = 24
24/2 = 12 units
