What are the measurements of x and y
Answers
So lets find each angle then
90 + 12 + 15 + x + x + x = 180
117 + 3x = 180
-117 -117
3x = 63
x = 21°
Same thing for the angle y
90 + 15 + 12 + y + y = 180
117 + 2y = 180
-117 -117
2y = 63
y = 31.5°
The whole is 360°
check:
31.5 + 31.5 + 15 + 15 + 12 + 12 + 90 + 90 + 21 + 21 + 21 = 360
360 = 360

5% of x=5
(5/100)x=5
x=(5*100) / 5
x=500/5
x=100
Answer: the number is 100.

x 100
5 over x is equivalent to 5% (5 over 100)
Cross multiply
Five times 100 is five hundred. Divide by five. x=100

Final answer:
To calculate interest over time, you need to use the compound interest formula because monthly deposits are being made. However, without more information on how frequently the interest was compounded, we can't find the exact total interest earned from a retirement plan with a 2.5% rate over 42 years with $520 monthly deposits.
Explanation:
The question asks how much interest was gained from investing in a retirement plan with a rate of 2.5% over 42 years. The total monthly deposits were $520. To calculate this, we need to use the simple interest formula which is I=PRT, where 'I' is the interest, 'P' is the principal amount (the initial investment), 'R' is the rate of interest, and 'T' is the period of time.
However, in this case, because the deposits were made monthly, this is not a simple interest problem but a compound interest problem. In such cases, the formula to calculate compound interest (which includes the initial investment amount and the interest earned) is A = P (1 + r/n) ^ nt, where:
- 'A' is the amount of money accumulated after n years, including interest.
- 'P' is the principal amount (the initial amount of money)
- 'r' is the annual interest rate (in decimal)
- 'n' is the number of times that interest is compounded per year
- 't' is the time the money is invested for in years
As we don't have enough information to conclude the precise amount (e.g., whether the interest was compounded annually, quarterly, monthly, or daily), we can't calculate the exact value of the interest earned.

4%=4/100=0.4/10=0.04/1=0.04
4% of sale=0.04 times sales
so we have
at least means >
so
earnings>2200
earnings=1900+comission on sales
commision on sales=0.04 times sales
2200<1900+0.04timessales
solve for sales
2200<1900+0.04 times sales
subtract 1900 from both sides
300<0.04 times sales
divide both sides by 0.04
7500<sales
he has to sell at least $7500 per month
