A lawnmower that regularly sells for $150 is on sale for $120. The price was decreased by percent.

Answers

Answer 1
Answer:

Step 1:

Let us first find the decrease in amount.

Decrease in amount = 150 -120 = $30

Step 2:

Now let us find the ratio of decrease in price to original price.

So the ratio is 1/5 or in decimal its 0.2.

Step 3:

To find percentage decrease we change this decimal number 0.2 two places to the right side, so it becomes 20 %

 The price decreased by 20%

So, the correct answer is A) Need more information.

NEED AS SOON AS POSSIBLE!!! Kaylee is mixing paint for an art project. She mixes 5 ounces of green paint with every 3 ounces of white paint. She needs 50 ounces of the paint mixture. I need it as a equation

Answers

Answer:

Step-by-step explanation:

Let Kaylee used the amount of green paint in the mixture = x ounces

and the amount of white paint = y ounces

Total amount of mixture = 50 ounces

Equation will be x + y = 50 ------(1)

Ratio of green paint to the white paint in the mixture = 5 : 3

⇒  x : y = 5 : 3

⇒ (x)/(y)=(5)/(3)

⇒ x = (5)/(3)y ---------(2)

Therefore, By solving these two equations by substitution method we can get the amount of green and white paint used in the mixture.

38.50 for 3 hours.

Calculate hourly wage by dividing both sides by 3

$12.83333333333333 per hour. let's round this to $12.83

So M = hourly wage * H = M = 12.83 * H

which of the following statements best describes the effect of replacing the graph of y = f(x) with the graph of y = f(x) − 11? (5 points) the graph of y = f(x) will shift up 11 units. the graph of y = f(x) will shift right 11 units. the graph of y = f(x) will shift left 11 units. the graph of y = f(x) will shift down 11 units.

Answers

the graph of y = f(x) will shift down 11 units.

Answer:

Step-by-step explanation:

Alright, lets get started.

When we add or subtract any thing from the function f(x), that is called vertical shift.

The vertical shift means graph will move up or down.

When something is added, the graph of f(x) goes up means vertical shift up.

When something is subtracted, the graph of f(x) goes down, means vertical shift down.

So, when 11 is subtracted from f(x), it means, the graph of f(x) will shift 11 units down.   :  Answer
