For every 6 students who purchase a bag of M&M’s, there are 5 students who purchase a pack of gum. Use M for the number of s

Assoli18 [71]

Answer:

M/6 = G/5

Step-by-step explanation:

We are given a relation between the numbers of students in two different groups. That relation can be used to write an equation.

<h3>Groups who bought M&Ms</h3>

If we consider M&M buyers to be 6 in a group, then the number of those groups is ...

M/6

<h3>Groups who bought gum</h3>

Similarly, the number of groups who bought gum will be ...

G/5

where there are 5 gum-buyers in each group.

<h3>Equation</h3>

The problem statement tells us that for each group of one kind, there is a matching group of the other kind. That is, the numbers of groups are equal:

M/6 = G/5

An angle measures 20° more than the measure of its supplementary angle. What is the measure of each angle?

nevsk [136]

Supplementary angles sum to 180 degrees.

So if one angle is 20 degree more than the other...

x+(x+20)=180

2x+20=180

2x=160

x=80

x+20=100

answer: 80° and 100°

There are 16 bacteria in a beaker.Four hours later there are 228 bactriea in the beaker.What is the rate of change per hour in t

saul85 [17]

Answer:

Rate of change per hour in the number of bacteria is r=0.28

Step-by-step explanation:

Given : There are 16 bacteria in a beaker and four hours later there are 228 bacteria in the beaker.

To find : What is the rate of change per hour in the number of bacteria.

Solution :

At initial number of bacteria is 16

After 4 hours number of bacteria is 228

Rate of change per hour is given by

$A=Pe^{rt}$

where A = total number of bacteria, P = initial number of bacteria, r= rate of change , t= time

$228=16(e^{4r})$

$14.25=(e^{4r})$

Taking log both side,

$log(14.25)=4r$

$1.15=4r$

$0.28=r$

Therefore, Rate of change per hour in the number of bacteria is r=0.28
