Answer:
The numerical length of JL is 6 units
Step-by-step explanation:
Here, we want to determine the numerical length of JL
Mathematically;
JL = JK + KL
2x + 8 = 5x + 7 + 4
2x + 8 = 5x + 11
5x -2x = 8-11
3x = -3
x = -1
But JL = 2x + 8
JL = 2(-1) + 8 = -2 + 8 = 6
Answer:
g = 2H/(m + r)
Step-by-step explanation:
mg + rg = 2H
g(m + r) = 2H
(g(m + r))/(m + r) = 2H/(m + r)
g = 2H/(m + r)
Find the rate in which both balls make one full rotation around the track.
Ball A:

It takes 30 seconds for Ball A to make a full rotation.
Ball B:

It takes 20 seconds for Ball B to make a full rotation.
Find the least common multiple of 20 and 30 to find the time at which they'll meet.
Multiples of 20: {20,40,60}
Multiples of 30: {30,60}
60 is the least common multiple of both 20 and 30.
The balls will meet again at
60 seconds.
Answer:
The total compound interest is $3,488.50, I hope I helped explain how to find total compound interest
Step-by-step explanation:
So the formula for this would be:
A = P(1+r/n)^nt
A = the amount of your principal plus interest, which is the total
P = stands for the principal, which is your original amount invested
r = shows the interest rate in decimal form
n = stands for the number of compounding periods
So to solve for the compound interest we would plug in our numbers in replacement for the letters
Answer:
What do you want your answer in? Exact or decimal form?
Exact form: 212/3
Decimal form 70.6
Step-by-step explanation:
Cancel the common factor of 8 and 6 for 53 * 4/3. Multiply 53(4/3), 212/3. This would be the answer for the exact form, decimal form is created by dividing 212 by 3, for 70.66666--.
