For A, you take 70% of 421,000 and subtract that from 421,000. You should solve like this: 421,000 - (0.7 x 421,000).

For B, you take 40% of 31.50 and add it to 31.50. (31.50 + (31.50 x 0.4).

This is all I can give for now. Glad to help you!

Answer:

A) Bacteria left after taking the new drug = 126,300 bacteria

B) The new cost is $44.10

C) the has to produce 181,819 drug to make $2 million profit.

Step-by-step explanation:

Given:

New drug eliminate 70% of bacteria. If there are over 100,000 bacteria after the new drug the patient has to take another drug which cost 40% more expense.

<u>Part A</u>

A new patient has 421,000 bacteria.

The new drug eliminate 70% of the bacteria.

Eliminated bacteria = 70% of 421,000

= \frac{70}{100} *421,000\\=0.7*421,000\\= 294,700

Bacteria left after taking the new drug = 421,000 - 294,700

Bacteria left after taking the new drug = 126,300 bacteria

<u>Part B</u>

The new cost 40% more than $31.50

New cost = $31.50 + 40% of 31.50

= = 31.50 + 0.4*31.50\\= 31.50 + 21.60\\= $44.10

The new cost is $44.10

<u>Part C</u>

The company produces them with $11 profit.

The company has to make $2,000,000 profit.

The number of drug produce = $2,000,000 divided by $11

= \frac{2000000}{11} = 181,818.18

The drug cannot be in decimal form.

So, the company has to produce 181,819 drug to make $2 million profit.

The area of a rectangle is 162/3 ft2 . The length is 61/4 . Find the width. Show all work
brilliants [131]

Answer:

I have gotten 216/61, but I am not sure if this is right.

Step-by-step explanation:

By using the "Keep It, Change It, Flip It" tactic, I was able to come up with an answer and simplify it.

1. Keep the original divisor.

    162/3

2. Change the sign.

    Division becomes multiplication.

3. The last fraction is reciprocated.

    61/4 becomes 4/61.
