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
To add fractions, find the lcd and then combine =13
X = 14
Y = 16
I hope I could help!
For this case we have the following system of equations:
Equating the values of y we have:
From here, we can clear the value of x.
We have then:
Then, we look for the value of y.
For this, we substitute x in any of the equations:
Answer:
The ordered pair solution of the system of equations, is given by:
Given The equation -2x(-2.8)=24, we are trying to find the value of X.
The first step is to devide both sides by 2
·-x(-2.8)=12
The next step would be to distribute.
·2.8x=12
Next we devide both Sides By 2.8 to get our final answer
·X=4.28
Although your choice answers are unclear, the answer is X=4.
