Answer:
In composite figures the total area of the composite figure should be broken up into smaller area comprising of rectangles, squares, circle, semi-circles, right angle triangles, isosceles triangles and right angled triangles.
All the areas should be calculated separately and finally should be added to give the total area of the composite area,
The need for subtraction arises only if the dimensions of each smaller area are not given.

Answer:
The answer, also the only answer, is C.
Step-by-step explanation:
A: 20 is 1/2 of 40, so you would arrive at Seneca Falls in half an hour.
B: Same as a, 2 is 1/2 of 4, so you would also arrive to school in half an hour.
C: 60 is double 30, so it would take two hours to get from Albany to New York City.
The sales price is 85% of the original $2,200, which can be calculated as follows: .85(2,200) = 1870 Assuming you meant 15% discount price..
Now we need to find a 7% sales tax, which can be calculated as follows:
.07(1870) = 130.90
Now we add the sale price and the sales tax: 1870 + 130,90 = $2000.90 for the total cost.
Answer:
65 girls play soccer
Step-by-step explanation:
I got this answer because if every 2 tennis girl there are 5 soccer girls I divided 26 by 2 and got 13 then I multiplied 13 by 5 and got 65
The decay factor of the exponential function given in the table is of .
<h3>What is an exponential function?</h3>
A decaying exponential function is modeled by:
In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem, we have that when x increases by 1, y decreases by a factor of 3, hence the decay rate r is found as follows:
