Convert 30% to a decimal:

30% = 0.30

Check each item by multiplying the original price by 0.30 (the 30% off sale). Subtract the product from the original price. If the sale price is the same, the pricing is correct. If they are different, the pricing is incorrect.

Amy takes a job as a car salesman. She makes $700 per car she sells, and she earned a $100 bonus when she agreed to work for the car dealership. Write an equation that shows how much Amy will have earned (E) after selling 'c' cars. Use that equation to determine how many cars. Amy must sell in order to have earned a total of $14,800. That is the unlock number.

ILL GIVE U BRANLIEST

Answers

Answer:

E = 700c + 100 and 21 cars

Step-by-step explanation:

Let c be the number of cars that Amy sells. The initial salary that Amy gets is 100, no matter how many cars that Amy sells. However, she also makes 700 dollars for every car she sells, or c. Therefore, we have the equation:

E = 700c + 100

with E representing how much money Amy gets. We use this equation for part B. She must make 14800 dollars, which we substitute for E, because that is how much she makes. Therefore, we have:

14800 = 700c + 100.

We solve this equation and get c = 21, so Amy has to sell 21 cars.

Answer:

To earn a total of $14,800 Amy would need to sell 21 cars (Read explanation for equation)

Step-by-step explanation:

$700 per sale of 1 car

$100 Bonus (1 time)

c=Cars

E=Earned

Equation:    E=(700•c) +100

To find how many cars amy would need to sell to reach 14,800, Replace "E" With 14800

14800 = (700•c) +100

How do you find dimensions of a cylinder with just the volume?

Answers

Answer:Since the volume of a cylinder formula involves the radius, you can solve for the radius and double it to find the diameter.

Write the formula. Volume=π⋅radius2⋅height.

Substitute the dimensions of the shape into the formula. Use 3.14 as the value for π. 791.28=3.14⋅r2⋅28.

Answers

Given diameter: r = d / 2,
Given area: r = √[A / (4 * π)],
Given volume: r = ³√[3 * V / (4 * π)],
Given surface to volume ratio: r = 3 / (A/V).


Some equations based on what is given :)
If given the diameter, divide by 2. For example if the diameter is 16, that would mean the radius would be 8. If the problem doesn’t state the diameter, divide the circumference by pi. So if the circumference was 24, that would make the diameter 7.639437268. From there you divide that by 2 to get the radius. Hope this helps!

Burger patties come packed 8 in a package, and burger buns come packed 12 in a package. We want to buy the least number of patties and buns possible, while still making sure that we have exactly one patty for each bun (no leftovers). How many packages of buns do we need to buy?

Answers

To find the answer you need to find the least common multiple of each number.

8, 16, 24
12, 24

They both have 24 in common and it’s the lowest multiple of both numbers. So in turn to have the same number of them you would need to get 3 packs of burger patties and two packs of burgers.

Hope this helps!! Have a great day ^w^

The least number of patties and buns possible is 4.

Given that, Burger patties come packed 8 in a package, and burger buns come packed 12 in a package.

What is the least common multiple?

The least common multiple is also known as LCM (or) the lowest common multiple in math. The least common multiple of two or more numbers is the smallest number among all common multiples of the given numbers.

The factors of 8 and 12 are given below:

8 = 2 × 2 × 2

12 = 2 × 2 × 3

LCM of 8 and 12 is 2 × 2 = 4

Therefore, the least number of patties and buns possible is 4.

What is 4a+8b in simplified form?

Answers

It is already simplified! 4a+8b

The simplest form of (4a + 8b) / 12 is (a + 2b) / 3.

Given is an expression (4a + 8b) / 12, we need to simplify it in simpler form,

To simplify the expression (4a + 8b) / 12, you can divide both the numerator and the denominator by their greatest common divisor (GCD) to reduce the fraction to its simplest form.

First, let's find the GCD of 4 and 12. The factors of 4 are 1, 2, and 4, and the factors of 12 are 1, 2, 3, 4, 6, and 12.

The largest number that appears in both sets of factors is 4, so the GCD of 4 and 12 is 4.

Dividing both the numerator and the denominator by 4, we get:

(4a + 8b) / 12 = (4(a + 2b)) / (4 x 3)

Canceling out the common factor of 4:

(4(a + 2b)) / (4 x 3) = (a + 2b) / 3

Therefore, the simplest form of (4a + 8b) / 12 is (a + 2b) / 3.
