Point A is located at -0.75 and point B 1/4 is located at on a number line.

Part A: Which expression shows how to find the distance between points A and B?

Answers

Answer:

The distance between Points A and B is 1.

Step-by-step explanation:

Given that Point A is located at -0.75 and Point B is located at 1/4 on a number line, to determine which expression shows how to find the distance between points A and B the following calculation must be performed:

1/4 = 0.25

-0.75 + X = 0.25

X = 0.25 - (-0.75)

X = 0.25 + 0.75

X = 1

Therefore, the distance between Points A and B is 1.

A pound is a(lager, smaller) unit than an ounce, so (divide, multiply) the number of pounds by 16 to find the number of ounces. Therefore, 2 pounds is equal to

ounces.

Part B:

you didnt give any context. But to turn pounds into ounces multiply it the pounds by 16 (2lbs. × 16 = 32oz.)

and once you have the total number of ounces divide it by how many ounces her mom drinks in a day (ex. 32÷4= 9) and if that number is larger than 7 then yes, theres enough coffee

Yes you gave her enough coffe

Benny, and his three friends went to lunch. The bill, before sales tas and tip, was $37.50. A sales tas of 8% was added. The group then tipped 18% on the amount before the sales tax was added. What was the total amount the group paid, inclouding tax and tip?

Answers

Hello! I believe that I have the answer.

My answer: The total amount was $47.79.

8% of $37.50 is $3. $37.50 + $3 = $40.50.

18% of $40.50 is $7.29. $40.50 + $7.29 = $47.79.

I hope that helps! Please let me know if my answer is incorrect.

The answer is 86

Following PEMDAS, which is:

parentheses

exponents

multiplication

division

addition

subtraction

I found that the answer was 86

Answer:

-10.

Step-by-step explanation:

Step 1: Explain/define

This problem contains more than one operation. This means we should solve this using a special acronym known as PEMDAS.

P (Parenthesis)

E (Exponents)

M/D (Multiplication/division, whichever comes first)

A/S (Addition/subtraction, whichever comes first)

This is the correct sequence of steps when solving expressions with multiple operations.

PEMDAS can be remembered using the mnemonic "Please Excuse My Dear Aunt Sally."

------------------------------------------------------------

Step 2: Solve.

REMEMBER PEMDAS!

Expression given: 4 × 3 + 2 × 9 - 40

There are no parentheses.

There are no exponents.

There is multiplication, but no division.

4 × 3 + 2 × 9 - 40

12 + 18 - 40

There is addition and subtraction. Remember to solve whichever comes first.

12 + 18 - 40

30 - 40

30 - 40 = -10.

I, therefore, believe the answer to 4 × 3 + 2 × 9 - 40 is -10.

Please let me know if you have any further questions.

Answer:

The radius and the diameter of the circle are 11 cm and 22 cm respectively.

Step-by-step explanation:

The radius of a circle is a line segment extending from the center of a circle or sphere to the circumference or bounding surface, while the diameter of a circle is a straight line passing from side to side through the center of a body or figure, commonly a circle or sphere. Since the diameter goes entirely across the circle while passing through the midpoint - or center - of a circle and the radius only goes from the edge to the midpoint, that means the diameter is twice as big as the radius. In this example, the radius is already given to you, which is 11 cm, based on the image. Using this, you can figure out the diameter of that circle would be [tex]11 * 2[/tex] or 22 cm. So the radius of the circle is 11 cm, while the diameter of the circle is 22 cm.
