Earlier this year in a drug bust in Shanghi, China, police seized 2.4 tons of methamphetamines. If a typical dosage is 50mg, how many doses is that bust, which the Chinese police prevented from being sold to the public?

Answers

Answer 1

Answer: 2.4 tons=2.4 tons*(1,000 Kg / 1ton)*(1,000,000 mg / 1 kg)=
=2,400,000,000 mg=2.4 x 10⁹ mg

Now, we solve this problem by the rule of three.

50 mg ---------------------1dose
2.4x10⁹ mg---------------- x

x=(2.4 x 10⁹ mg * 1 dose) / 50 mg=48,000,000 doses.

Answer: 48,000,000 doses

Variable g is 8 more than variable w. Variable g is also 2 less than w. Which pair of equations best models the relationship between g and w?g = 8w
g = w + 2

w = g + 8
w = g − 2

w = 8g
w = g + 2

g = w + 8
g = w − 2

Answers

Answer:

g = w + 8

g = w − 2

Step-by-step explanation:

Variable g is 8 more than variable w. Variable g is also 2 less than w

Variable g is 8 more than variable w

8 more means we add with variable w. for key word 'is' use = symbol

So the equation for Variable g is 8 more than variable w

g= w+8

Variable g is also 2 less than w

For 2 less than w we subtract 2 from 'w'

So Variable g is also 2 less than w

g= w-2

The correct system of equations is:

g = w + 8
g = w − 2

The super speedway at Daytona International Speedway is 2.5 miles long. The road course there is 1.4 times as long as the super speedway. How long is the road course?

Answers

Answer:

3.5 miles

Step-by-step explanation:

From the question, we have the following information:

The super speedway at Daytona International Speedway is = 2.5 miles

long

The road course there is = 1.4 times as long as the super speedway.

How long is the road course?

The length of the road course is calculated as:

1.4 × length of the super speedway

1.4 × 2.5 miles

=>3.5 miles

Therefore, length of the road course I s 3.5 miles.

B) 27.44 mg
C) 45.24 mg
D) 91.11 mg

Answers

A(t) = 50 e^-(0.1 x 6) = 50 e^-0.6 = 50 x 0.5488 = 27.44 mg
