Answer:

70 x 12 1/2 = 875.

Step-by-step explanation:

Step 1.) When you multiply fractions, you put whole numbers over one.

Step 2.) Then, you change whole numbers with fractions, to improper fractions.

Step 1.)

70/1 x 12 1/2

Step 2.)

70/1 x 25 / 2.

And then we solve!

70 x 25 = 1750

1 x 2 = 2.

1750 divided by 2 = 875.

Hope this helps!!

Cassie bakes cookies and brownies for the school bake sale. Each cookie will sell for $0.50 and each brownie will sell for $0.75

katovenus [111]

T= total money raised
c= # cookies sold
b= # brownies sold

Total money earned equals the price per cookie times number of cookies sold plus the price per brownie times the number of brownies sold.

T= ($0.50 * # c) + ($0.75 * # b)

T= $0.50c + $0.75b

ANSWER: The expression showing money earned is T= $0.50c + $0.75b

Hope this helps! :)

A batch of 330 samples of rejuvenated mitochondria contains 6 that are mutated (or defective). Two are selected from the batch,

Leno4ka [110]

Answer:

(a) Probability = 0.01520

(b) Probability = 0.00028

(c) Probability = 0.96391

Step-by-step explanation:

Total mitochondria = 330

Defective = 6

(a) Without replacement, if the first selection contains a defective mitochondria, we have a total of 5 defective remaining from a total of 329 mitochondria. Thus the probability the second one is defective Given the first one was defective will be :

Probability second is defective given the first one is not = 5 / 329 = 0.01520

(b) The probability the first is defective is : 6 / 330 = 0.01818

The probability the second is defective (without replacement) = 5 / 329 = 0.01520

The probability both are defective = 0.01818 * 0.01520 = 0.00028

(c) Probability the first one is acceptable = 324 / 330 = 0.98182

Probability the second one is acceptable = 323 / 329 = 0.98176

Probability both are acceptable = 0.98182 * 0.98176 = 0.96391
