Sandy bought 12 7/8 pounds of peaches to make jam. She and her mother ate 0.75 of a pound of the peaches before making the jam. They used 9 3/8 pounds of the peaches to make the jam. How many pounds of peaches were left over?

A. 3 1/4
B. 3
C. 2 3/4
D. 2 1/4

Step-by-step explanation:

initial amount: 12 7/8 lbs

ate: 0.75 lbs= 3/4 lbs = 6/8 lbs

used: 9 3/8 lbs

remainder: 12 7/8 - 9 3/8 - 6/8

= 3 1/8 - 3/8

=2 6/8 = 2 3/4 = C

A local hamburger shop sold a combined total of 613 hamburgers and cheeseburgers on Wednesday. There were 63 more cheeseburgers sold than hamburgers. How many hamburgers were sold Wednesday

Answers

Answer:

This problem can be solved through the creation of a system of equations relating the number of hamburgers (x) and cheeseburgers (y).

Having a combined total of 603 hamburgers and cheeseburgers can be written as x+y=603 and having 53 more cheeseburgers than hamburgers can be written algebraically as y=x+53.

To solve the system:

x+y=603

y=x+53

Substitute what y equals in the second equation for y in the first equation:

x+(x+53)=603

2x+53=603

-53 -53

2x=550

2 2

x=275 hamburgers

To solve for the number of cheeseburgers, substitute 275 for x in either equation.

y=x+53

y=275+53

y=328 cheeseburgers

To double check your work, make sure that 275+328=603 and that 328=275+53. Since both are true, you have solved for the number of hamburgers (275) and cheeseburgers (328).

Step-by-step explanation:

Answer: 58 cheeseburgers

What is the image of the point (6, -4) when rotated 180 degrees anticlockwise about the origin?

(-6, -4)

(-6, 4)

(4, 6)

(-4, -6)

the answer is (-6, 4).

If the coordinate is rotated 180 degrees anticlockwise about the origin, the resulting coordinate will be (-6, -(-4)) = (-6, 4)

Given the coordinate point (x, y). If this coordinate is rotated 180 degrees anticlockwise about the origin, the resulting coordinate will be at (-x, -y)

We can see that the given coordinates were negated to get the resulting coordinate.

For the image of the point (6, -4), if the coordinate is rotated 180 degrees anticlockwise about the origin, the resulting coordinate will be (-6, -(-4)) = (-6, 4)

While she was at work today a large box of metal rivets fell from a 20-ft.-high overhead shelf, striking her outstretched arm and knocking her to the ground. The ambulance personnel reported that she had lost quite a bit of blood at the accident scene and was "knocked out" when they arrived. To minimize further hemorrhage, the paramedics applied a pressure bandage to her arm.You meet the paramedics as they bring Mrs. Morgan into the emergency room and begin to assess her for injuries. She is awake and alert, but complaining of severe left arm and back pain, plus she has a "killer headache." To fully examine her injuries you remove four blood-soaked bandages from her arm. You notice a large open wound on her arm with what appears to be bone tissue sticking out of the skin She also has bruises covering her left shoulder, left wrist, and lower back. To determine the extent of her injuries Mrs. Morgan undergoes several x-rays, which reveal the following: 1) fracture of the left humerus at the proximal diaphysis 2) depressed fracture of the occipital bone, 3) fracture of the 3rd lumbar vertebral body. Define the following terms, used in the case and also in associated questions. a. hemorrhage b. fracture c. proximal d. diaphysis Stacy wants to go on a vacation that will cost her at least $1540.
