This figure represents a design that is sewn onto a blanket. The semicircles are a solid green fabric and the square is a floral fabric. The area of the solid green fabric is 18π square inches.
What percent of the design is solid green fabric?
Use 3.14 for π. Round your answer to the nearest whole percent.
Answers
Answer:
61%
Step-by-step explanation:
Because there are 4 semicircles, 18/4=4.5, so the area of each semicircle is 4.5 pi. Therefore the area of a whole circle is 9 pi, so the radius of the circle is 3. That means the diameter of the circle, which is also the side of the square, is 6, so the area of the square is 36. Therefore the percent of the design that is green fabric is:
18pi/18pi+36
= 56.52/92.52
= about 0.611, which rounds to 61%.
Answer:
61%

Seki, a professional bike racer, takes out a loan to buy her first high-end bike. The bike costs $seven thousand, five hundred, and the simple interest loan is for thirty months. She calculates that she will end up paying $seven hundred fifty in interest over the life of the loan.
.
What is the interest rate on Seki's loan?
The following sentence or sentences contain missing information in the form of one or more blanks. For each blank, there will exist a corresponding input field. Use the input fields to complete the sentence or sentences.
Interest Rate =
%
What is the total amount Seki will pay when the loan is due?
Balance = $
Answers
Answer: Seki's interest rate for the bike is 33.33% each year; Seki will owe $8250 at the end of the loan.
Step-by-step explanation:
To calculate the simple interest rate, the equation is: r = (1/t)(A/P - 1)
Where:
r - interest rate per year (in decimal format)
t -time (loan time in years)
A - total accrued amount (initial price paid + amount of interest paid)
P - principle (initial price paid)
For this scenario:
r = (1 / 30)(8250 / 7500 - 1)
- simplify both sets of parentheses: 1 / 30 and 8250 / 7500
r = (.033333)(1.1 - 1)
- simplify the second set of parentheses
r = (0.033333) x 0.1
- multiply
r = 0.0033333
- convert r (as a decimal) to R (as a percentage) by multiplying r x 100
R = .3333
The interest rate on Seki's loan is 33.33%
The total amount Seki will pay:
equation for total due: A = P + I
Where:
A - total accrued amount (initial price paid + amount of interest paid)
P - principle (initial price paid)
I - amount paid in interest that accrued over time
For this scenario:
A = 7500 + 750
A = 8250
Seki will pay $8250 when the loan is due.

Answer:
D is the right choice and no you cannot fit the pizza inside the box.
Step-by-step explanation:
D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666...

Answers
Answer:
BD = √(18² +4²) = √340; AD = √(12² +(√340)²) = 22AD = √(12² +18² +4²) = 22Step-by-step explanation:
You want the space diagonal of the given box (a) using the Pythagorean theorem twice, and (b) using the formula.
Pythagorean theorem twiceThe length of BD can be found from ...
BD² = BC² +CD²
BD² = 18² +4² = 340
BD = √340 ≈ 18.439
and
AD² = AB² +BD²
AD² = 12² + 340 = 484
AD = √484 = 22
The lengths of the face and space diagonals are ...
BD = √340 ≈ 18.439AD = 22FormulaNo formula is given as part of the problem statement. We can simplify the above calculations to get ...
AD² = AB² +BD²
AD² = AB² +BC² +CD²
AD = √(AB² +BC² +CD²) . . . . . . a reasonable formula
AD = √(12² +18² +4²) = √(144 +324 +16) = √484
AD = 22

Answer:
2t³
Step-by-step explanation:
For this problem, we are dividing 16t⁴ by 8t. First, we should separate both of these terms into parts we can work with individually. So, we can easily divide 16 by 8, and we can also easily divide t⁴ by t. After solving each of these smaller problems we can get our solution.
First, 16 divided by 8 is 2. This is the first part of our answer. t⁴ divided by t is t³; this is because when dividing terms with the same base, we can subtract the exponents to get the final exponent. The exponent for t⁴ is 4, and the exponent for t is an invisible 1 (t = t¹). 4 - 1 = 3, so t⁴ divided by t is t³.
Putting those two answers together gives us 2t³.

Amanda earns 53 dollars each week working part-time at a bookstore. She earns one additional dollar for each book that she sells.
Let A be the amount (in dollars) that Amanda earns in a week if she sells B books.
Write an equation relating A to B. Then use this equation to find the amount of money Amanda earns if she sells 15 books.
Answers
Step-by-step explanation:
The equation relating A to B is:
A = 53 + B
To find the amount of money Amanda earns if she sells 15 books, we substitute B = 15 into the equation:
A = 53 + 15 = 68
Therefore, Amanda earns 68 dollars if she sells 15 books.
Answer:
The equation relating A to B is:
A = 53 + B
This is because Amanda earns $53 each week without selling any books, and earns an additional $1 for each book she sells.
To find the amount of money Amanda earns if she sells 15 books, we simply plug in B = 15 into the equation:
A = 53 + 15
A = 68
Therefore, if Amanda sells 15 books in a week, she will earn $68

Now let's use this expression to answer the next two parts of this question!

Here's what it looks like using our expression we made
# of songs = 12 ( 24)
Solve using a calculator
# of songs = 288
c. To find how many hours it will take to play 60 songs, we will put it in place of the LEFT SIDE of the equation that says "# of songs"
Let's solve it now!

Answers
Answer: Hey give me 1 hour and ill answer it I'm doing odessyware rn so Ill get back to you later appreciate yo patients.
Step-by-step explanation:
Then, if we want to make 30 servings, we need to use that recipe 3 times. (because x*10 = 30, then x = 30/10 = 3)
This would be equivalent to multiply each ingredient by 3.
for 30 cupcakes we need:
3 cups of vegetable oil.
3 cups of all-purpose flour
(because for each one of these ingredients we needed only 1 cup to make 10 cupcakes).
for 10 cupcakes we need 1 teaspoon of vanilla.
for 30 cupcakes we need 3 teaspoons of vanilla, the difference is 3 - 1 = 2.
So the difference is 2 teaspoons.
About which quantities we should round are those where we may have mixed numbers or big numbers.
For example, we have 4 tablespoons of sour cream for 10 servings, then for 30 servings we should have:
3*4 = 12 tablespoons.
We could round this down to 10 tablespoons.
