Ms. Federman graded 5 papers in 40 minutes. At this rate, how many minutes will it take her to grade 30 papers?
Ksivusya [100]

Answer:

240 minutes

Step-by-step explanation:

If it's 40 minutes for just 5 papers, we need to figure how many minutes it would take to grade just 1. So you have to divide 40 by 5 which is 8. Then 8 time 30 which is 240.

An experiment observing the growth of two germ strand populations finds these patterns.
Mice21 [21]

Answer:

R(x) = (1.3)^{3x-8}

Step-by-step explanation:

Given

A(x) = (1.3)^{x + 9}

B(x) = (1.3)^{4x + 1}

Required

Ratio B(x) to A(x)

This is calculated as:

R(x) = B(x) : A(x)

Express as fraction

R(x) = \frac{B(x) }{A(x)}

Substitute: A(x) = (1.3)^{x + 9} and  B(x) = (1.3)^{4x + 1}

R(x) = \frac{(1.3)^{4x+1}}{(1.3)^{x+9}}

Apply law of indices

R(x) = (1.3)^{4x-x+1-9}

R(x) = (1.3)^{3x-8}
