While it says they are joined, we will have to solve them as seperate shapes then add the area at the end.
Since we have a half circle and a triangle, the formulas for the areas are as follows
Half-Circle
it is the regular circle formula, but divided by 2, since it is half the size of a regular circle
(pi*r^2)/2
Triangle
it is the formula for the area of a triangle, being base times height divided by 2
(b*h)/2
Plug in the numbers into the appropriate variables, then add. you should get a total area of 49.274 ft^2. Then you just multiply the final area by the $1.50 to get the cost of the mini gold course.
The answer would be:
-7sqrt(6x)/4x^3
12,000 × .75= 9,000 then multiply by 4. Your total is 36,000
9514 1404 393
Answer:
10%
Step-by-step explanation:
We assume the "sum" being referred to in both cases is the principal amount invested. The simple interest formula tells you ...
I = Prt . . . . . . interest on P invested at annual rate r for t years
We have ...
Filling in these values, we get ...
0.3P = Pr(3)
0.1 = r . . . . . . . . divide by 3P
The interest rate is 0.1×100% = 10% per year.
