A mover is loading an elevator with many identical 48-pound boxes.
The mover weighs 185 pounds. The elevator can carry at most 2000 pounds.
Write an inequality that says that the mover will not overload the elevator on a particular ride.

a. Solve your inequality and explain what the solution means.

b. Graph the solution to your inequality on a number line.

Answers

Answer:

Step-by-step explanation:

a) After solving inequality , we get x ≤ 37.81 which meant number of boxes must be less than or equal to 38 approximately.

b) The graph is attached below.

What are inequalities ?

When two values are compared , an inequality represents whether one is greater than, less than, or not equal to the other.

It is given that the elevator can carry at most 2000 pounds of load. The weight of mover is 185 pounds. Also a mover is loading an elevator with many identical 48-pound boxes.

Let's assume that the number of boxes is x.

Then the inequality can be written as :

48 × x + 185 ≤ 2000

Solving the inequality to get the value of x :

48x ≤ 2000 - 185

48x ≤ 1815

x ≤ 38 (approximate)

It meant

b) The graph for inequality which is 48 × x + 185 ≤ 2000 or say x ≤ 38 is shown below.

Therefore , the answers are :

a) After solving inequality we get x ≤ 37.81 which meant number of boxes must be less than or equal to 38 approximately.

b) The graph is attached below.

Use the original price and the markdown to find the retail price.

Original price: $80; Markdown: 20%

Answers

Answer:

$64

Step-by-step explanation:

20% of 80 = 16

$80 - $16 = $64

Answer:

$64

Step-by-step explanation:

1. Approach

Multiply the original price by the markdown, then subtract the result from the original price.

2.Find the amount by which the item was marked down

Multiply the original price by the percent by which it was marked down.

Original price * markdown

80 * 20%

*don't forget to convert the percent to a decimal by dividing the percent by 100

80 * 0.2

= 16

3. Find the new price

Subtract the amount by which the product was marked down from the original price;

original_price - markdown

80 - 16

= 64

Area of Shaded Region ≈ 0.23 cm^2

Step-by-step explanation:

Simple Question.

The diameter of the circle is 0.4 m, so the radius = 0.4/2 = 0.2 m.

The area of the circle = πr^2 = π(0.2)^2 = 0.04π

The area of the rectangle = 0.9*0.4 = 0.36

The area of the shaded region = 0.36 - 0.04π (π => 3.14) = 0.36 - 0.1256 = 0.2344 ≈ 0.23 cm^2

According to the histogram, in what percentage of games did the team score between 77 and 92 points?
Round your answer to the nearest percent.

Answers

umm im older and I dont even understand that

The percentage of games did the team score between 77 and 92 points is 78%.

What is Percentage?

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

We have,

Total games = 3 + 6 + 8 + 1 =18

and, number of games in which points between 77 and 92.

= 6 + 8

= 14

Now, the percentage of games did the team score between 77 and 92 points

= 14/18 x 100

= 77.777%

= 78%

In which equation would you multiply both sides by 4.5 to get the variable alone?
A. 6.1p = 4.5
B. p ÷ 6.1 = 4.5
C. p ÷ 4.5 = 6.1
D. 4.5p = 6.1

Answers

Answer:

Step-by-step explanation:

p/4.5 = 6.1

to isolate the variable do the opposite action

p/4.5 = 6.1

as p is divided by 4.5, you must multiply both sides by 4.5

p/4.5 ×4.5 = 6.1 × 4.5

p = 27.45
