Question

To express ​7.5 % as a​ decimal, _______, ___________ and remove the percent sign.

▼ move the decimal point  [two] [three] [one] places to the [left] [right]

▼ leave the number as it is.

▼ remove the dollar sign.

▼ divide by 100.

Answer:

▼ move the decimal point  [two] places to the [left]

▼ divide by 100.  

Step-by-step explanation:

Given

[tex]Number = 7.5\%[/tex]

Required

Express as decimal [Select all correct options]

From the list of given options, the correct options are:

▼ move the decimal point  [two] places to the [left]

▼ divide by 100.  

To prove that the options are correct:

(1)

▼ move the decimal point [two] places to the [left]

7.5% becomes 0.075%

▼ Remove the percent sign

0.075% becomes 0.075

So:

[tex]7.5\% = 0.075[/tex]

(2)

Divide by 100

7.5% when divided by 100 is: 0.075%

Remove the % sign, we have: 0.075

x° = 118°

y° = 180° - (22° + 180° - x°)

y° = 180° - (22° + 180° - 118°)

y° = 180° - 22° - 180° + 118°

y° = 118° - 22°

y° = 98°

The answer to you question is x=118 because it’s parallel to the other angle y=96

Amanda uses the recipe shown to make trail mix for a camping trip. How many cups of M&M's will she need to make 180 cups of trail mix?

Answers

Answer:

40 cups

Step-by-step explanation:

7 part nuts and 2 parts M&M makes up 1 trail mix

7 and 2 part = 9 parts in total

There are 180 cups in total, so each part would be:

180/9 = 20 cups = 1 part

Now, we know there are 2 parts M&Ms and there are 20 cups in a part, so:

M&Ms required = 2 * 20 = 40 cups

A group of friends wants to go to the amusement park. They have $243.25 to spend on parking and admission. Parking is $15.75, and tickets cost $22.75 per person, including tax. How many people can go to the amusement park?

Answers

Answer: 10 people

Step-by-step explanation:

Parking needs to be paid for but if all friends are going together, they need to only pay once for parking.

The amount spent on just tickets is therefore:

= 243.25 - 15.75

= $227.50.

If $227.50 was for tickets alone, the number of tickets they could buy is:

= Total amount left/ Price of tickets

= 227.50 / 22.75

= 10 people
