Answer:
8x + 12
Step-by-step explanation:
It would be 4 x 2x = 8x + (4 x 3) = 8x + 12
Answer:
A = 20.25π sq meters
Step-by-step explanation:
C = 2πr
9π = 2πr
divide π from each side to get:
9 = 2r
r = 9/2 or 4 1/2
A = πr²
A = π (4.5²)
A = 20.25π
Answer:
The amount of money originally invested which is the principal P = 5,000
Step-by-step explanation:
Using the compound interest formula, the return on investment can be represented on the interest function as;
f(x) = P(1+r)^x
Where
P is the principal which is the initial investment.
r = rate Proportion
x = time (number of years)
Comparing to the given function;
f(x) = 5,000(1 + 0.04)^x
We can see that;
Principal P = 5,000
Rate r = 0.04
time = x
The amount of money originally invested which is the principal P = 5,000
About 31.5% when rounded.
This is because you have to start with the probability of each urn. The first urn has 13 total balls (5 white and 8 yellow). Since 5 of them are white, the odds of pulling a white ball are 5/13. Then find the same for the second urn (9 white and 2 yellow). Therefore there are 11 total balls and 9/11 chance of getting a white one. After finding both, multiply them together to get the answer.
