Answer:

Bill: 912

Magda: 916

916>912

Magda's weighs more

Step-by-step explanation:

Bill has a bike that weighs 57 pounds. Magda has a bike that weighs 53 pounds. She adds a bell and basket to her bike. The bell weighs 14 ounces and the basket weighs 3 pounds and 6 ounces. Does Magda's bike with its new bell and basket weigh more than Bill's bike? Complete the explanation.

Before we begin, keep in mind that 1 pound = 16 ounces

Thus, Bill's bike must weigh 57 * 16, or 912 ounces

Magda's bike is given to weigh 848 + 14 + 54 = 916 ounces

Because 916 is bigger than 912, Magda's bike weighs more.

I hope this helps! Feel free to ask any questions!

916 is bigger that 912

the area of a yard is 192 yd2 what is the perimeter

Answers

Answer:

if its a square this is your answer 36864 if its a rectangle this is your answer 384

Step-by-step explanation:

u really didnt give enough info and im not sure if that 2 is a typo but if ur finding the area of a square thats the asnswer

Answer:

the perimeter is 32sqrt(3) yd, or approximately 55.4 yd

Step-by-step explanation:

A square has 4 congruent sides, so if the length of 1 side is s, the perimeter is 4s. Also, the area of a square is the side squared, or A = s^2.

A = s^2

s^2 = 192 yd^2

Take the square root of both sides.

s = sqrt(192)

s = sqrt(64 * 3)

s = 8sqrt(3)

P = 4s

P = 4 * 8sqrt(3) = 32sqrt(3)

Answer: the perimeter is 32sqrt(3) yd, or approximately 55.4 yd

A student translated the phrase below into an algebraic expression, and then evaluated it for g = one-fourth. Is the student’s work correct?
one-third more than the product of four and a number; evaluate when g = one-fourth

The expression is StartFraction 4 Over g EndFraction + one-third; for g = one-fourth. StartFraction 4 Over 1 EndFraction divided by one-fourth + one-third = StartFraction 4 Over 1 EndFraction times StartFraction 4 Over 1 EndFraction + one-third = 16 + one-third = 16 and one-third.
Yes, the student’s work is correct.
No, the student divided the fraction incorrectly
No, the student made an error when substituting.
No, product means multiplication, and the student wrote a division expression.

When Kate plays basketball, she usually makes 12.5% of her shots. Design and conduct a simulation to find the experimental probability that she makes 3 of her next 10 shots. Complete the justification.

Answers

Answer:

If Kate usually makes 12.5 % of her shots, making 3/10 shots (30%) will be uncommon. We can find the chance of her making 3/10 shots by multiplying 125/1000 and 3/10. This yeilds a result of 0.0375, which is 3.75%.

l=24in

Step-by-step explanation:

P=2(l+w)

l=P

2﹣w=68

2﹣10=24in

24 inches because if you add the two width you get 20 and then do the equation 68-20=48. Divide that by 2 and then you get 24 so then that’s the length
