Work:
Here, you could make a proportion. 

 6      x
---- x ----
30    100 

6 * 100 = 600
30 * x = 30x

600 / 30 = 20

Hi!

So we know that there are 30 people over 100, and 6 of them are male. That means the the rest are female. We just have to find out how much the rest is. 

To do that, we subtract
30-6 = 24

The answer is 24.

Hope this helps! :)

John should receive about 7200 milligrams of the drug.The unit conversion given is,1 lb =0.45 kg.

<h3>What is weight?</h3>

The weight of matter is found as the product of the mass and the gravitational acceleration.

Unit conversion;

1 lb =0.45 kg.

Dosage of a drug =  200 mg / kilogram

John weighs  = 80 lb

1 lb =0.45 kg.

80 lb = 36 kg

According to the weight the drug should he receive is;

Dosage of a drug =  200 mg / kilogram  × 36

Dosage of a drug = 7200 milli gram

Hence, John should receive about 7200 milligrams of the drug.

To learn more about the weight refer;

Use inductive reasoning to predict the next line in the pattern. Then perform the arithmetic to determine whether your conjectur
iren2701 [21]

Answer:

8(5) + 8(25) + 8(125) + 8(625) +8(3125)= 10(3125 - 1)=31240

Hence proved Conjecture is correct

L.H.S=R.H.S

Step-by-step explanation:

Consider the pattern:

8(5)=10(5-1)=40

8(5) + 8(25) = 10(25 - 1) =240

8(5) + 8(25) + 8(125) = 10(125 - 1) =1240

8(5) + 8(25) + 8(125) + 8(625) = 10(625 - 1)=6240

According to inductive reasoning next term of pattern will become:

8(5) + 8(25) + 8(125) + 8(625) +8(3125)= 10(3125 - 1)=31240

Checking whether conjecture is correct or not:

Consider L.H.S:

8(5) + 8(25) + 8(125) + 8(625) +8(3125)

40+200+1000+5000+25000

31240

R.H.S:

31240

Hence proved Conjecture is correct

L.H.S=R.H.S
