With the information given we have:

Where W is the weight, k is the proportionality constant and r is the radius of the can's radus. Remember that the weight varies jointly so this key word means that you need to multiply the mentiones parameters by a proportionality constant k.
We simply need to reorganize the expression and isolate k for the frst answer:

Replacing by all the appropiate values we get:

For the second part knowing k we have:
Answer:
$119.57
Step-by-step explanation:
We have to find present value of annuity to find the monthly payment.
Given,
Present value, PV = $4,000
Down payment = $4,000 × 10% = $400
Remaining present value = $(4,000 - 400) = $3,600
Interest, i = 12% = 0.12
As we need monthly payment, the interest rate will be monthly = 0.12/12 = 0.01.
Number of period, n = 3
monthly payment, m = 12
We know,
Present value of annuity = PMT × 
$3,600 = PMT × 
or, $3,600 = PMT × 30.1075
or, PMT = $119.57
Monthly payment should be $119.57
Answer:
50%
Step-by-step explanation:
4 and 6 make 10.
and there is 10 yellow marbles.
meaning it can be split 50% -50
Answer:
A triangle is 180 degrees. Imagine that two angles would be given as maybe 89 and 30 degrees. With these two angles already given you can find the last third angle by adding the 2 given angles and subtracting it from 180. There fore it would look like 180-119=61. 61 would be your unknown angle degree.
