for question 1
Area of Base B =45×25 = 1125 cm²
perimeter of base P = 2(45+25) = 140 cm
Height = 15 cm
Using the formula
Surface area = 2B + Ph
A = 2×1125 + 140×15= 4350 cm²
Voume = Bh = 1125×15= 16875 cm³
For question 2,
Area of base = 7× 5/2= 17.5 cm²
Perimeter of base = (7+7+7) = 21 cm
Surface area = 2B + Ph
Surface area of prism = 2×17.5+ 21×10 = 245cm²
Volume = Bh = 17.5×10 = 175 cm³

Kim deposited $1,422 into a savings account. After 5 years, she had a total of $1,635.30 in her account. What is the interest rate?
With step by step explanation = Brainliest
Answers
Answer:
don't know
Step-by-step explanation:
ok please mark mr brainlist
Answer:
3%
Step-by-step explanation:
Interest rat is calculated by using the equation A = P(1 + r)^n
A is the amount after interest. Here, it is 1635.30
P is the principal, or base, amount. Here, it is 1422
r is the rate at which there is interest. It is what we need to find out.
n is the amount of years interest is calculated for. Here, it is 5
Now that we have everything, we calculate:
1635.30 = 1422(1 + r)^5
Now we have to get r on one side of the equation by itself:
Divide both sides by 1422:
1635.30/1422 = (1 + r)^5
5√(1655.30/1422) = 1 + r
5√(1.16406469) - 1 = r
Now r is on one side of the equation.
The 5th root of 1.16406469 is 1.03084987
1.03084987 - 1 = 0.0308, so it is 3%
The 5√ is the 5th root of the numbers
Or it's 2.835 percent I don't know

A golf course has a circular island of grass with a diameter of 15 yards. The mowing company charges $6.50 per square yard. How much will the golf course have to pay to maintain the grass on the circular island?
Answers
Answer:
about $1148.06
Step-by-step explanation:
Your goal is to find the area of the island of grass and multiply that area by the cost per square yard.
Area = radius * radius * pi
You are told that the diameter = 15 yards. We also know that the radius that we need is half of the diameter. Radius = 7.5 yards.
This means that the Area = 7.5 * 7.5 * 3.14 = 176.625 square yards
Then we multiply by the cost per square yard:
176.625 * 6.50 = 1148.06 is your answer
Will cost about $1148.62

Janet can make 1/2 of a necklace in 20 minutes. At this rate, how many necklaces can Janet make in 2 hours?
Answers
Answer:
3 necklaces
Step-by-step explanation:
2 hours = 120 minutes
1 necklace in 40 minutes
120/40 = 3
3 necklaces
Answer:
3 necklaces
Step-by-step explanation:
2 hours needs to be in the same units as the 20 minutes
2 hours = 2 * 60 minute = 120 minutes
Now we can use ratios to solve
1/2 necklace x necklaces
-------------------- = ----------------
20 minutes 120 minutes
Using cross products
1/2 * 120 = 20x
60 = 20x
Divide by 20
60/20 = 20x/20
