Answer:
16.86 ft/s
Step-by-step explanation:
Given that
Speed of the carousel, s = 14 rpm
Distance from the carousel, d = 23 ft
To start with, we convert the given speed to revolution per second, so that
s = 14/60 rev/sec
To find the needed speed, we use the formula
v =2πnR, remember that Diameter = 2R, so we substitute D for 2R and get πnD
v = πnD, and we use this to find our needed velocity
v = 3.142 * 14/60 * 23
v = 72.266 * 14/60
v = 16.86 ft/s
Therefore the boy must run at a speed of 16.86 ft/s in order to be able to match the carousel and jump on it
Amount after 15 years = 6700( 1 + 0.046/2)^(2*15) = 13,253.90
Well we know she filled up her car 11 times each with 14 gallons.
All we have to do is multiply 11 by 14
11 x 14 = 154
Now the question says to estimate. And our answer can be rounded down to 150 gallons.
So your answer is..
B.) 150 gallons.
Good Luck! :)
The answer is 64. Hope it helps you
So just add 2 1/2 = 2.5and 1 1/4= 1.25 and that will equal, 3.75 cups in other words that will equal 3 3/4.cups of sugar total.
