A function is a relationship between inputs where each input is related to exactly one output.

4 in the function w(b) = 4b represents that each bag of dog food lasts 4 weeks.

Option C is the correct answer.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the function are 3 and 5

The inputs of the function are 1 and 2.

We have,

w(b) = 4b

w = number of weeks.

b = number of bags.

We see that,

when b = 1, w = 4

when b = 2, w = 8

when b = 3, w = 12

This means that,

1 bag of dog food will last for 1 week.

2 bags of dog food will last for 8 weeks.

3 bags of dog food will last for 12 weeks.

4 bags of dog food will last for 16 weeks.

Thus,

4 in the function w(b) = 4b represents that each bag of dog food lasts 4 weeks.

Option C is the correct answer.

Answer:

zero point three two meter

Step-by-step explanation:

Given

[tex]Measurement = 0.32\ meter[/tex]

Required

How should it be pronounced

From the measurement above, we can see that it contains a decimal point.

Using the rules of decimal point,

The number before the decimal point will be treated as 1 number and will be pronounced as such.

While numbers after the decimal will be treated as individual digits and will be pronounced individually.

Hence, the pronunciation of 0.32 meter is zero point three two meter

150 boys were enrolled in 2012

Step-by-step explanation:

Let the number of boys enrolled in 2012 be x

Let the number of girls enrolled in 2012 be x + 200

Ratio of boys to girls in 2012 enrollment = 3/7

Now;

3/7 = x/x + 200

7x = 3(x + 200)

7x = 3x + 600

7x - 3x = 600

4x = 600

x = 600/4

x = 150 boys

Hence, 150 boys were enrolled in 2012

Step-by-step explanation:

Max swims the breaststroke for 4 laps at the speed of 50 meters per minute. He then switches to the backstroke and swims another 4 laps at the speed of 25 meters per minute.

a) If length of the pool is d meters, how long did it take Max to complete 4 laps breaststroke?

b)  How long did it take Max to complete 4 laps backstroke?  

c) It took him 2 minutes longer to complete 4 laps backstroke than 4 laps breaststroke. Write the equation that describes this fact.

d)  What is the length of the swimming pool?

Solution:

a) Speed is the ratio of distance to time, it is given as:

speed = distance/time

1 lap = d meters, hence:

4 laps = 4d meters

Max swims the breaststroke at 50 meters per minute. Let us assume the time taken to complete 4 laps is [tex]t_1[/tex] minutes hence:

50 = 4d/[tex]t_1[/tex]

[tex]t_1\\[/tex] = 4d/50

[tex]t_1[/tex] = 2d/25 minutes

b) 1 lap = d meters, hence:

4 laps = 4d meters

Max swims the backstroke at 25 meters per minute. Let us assume the time taken to complete 4 laps is [tex]t_2[/tex] minutes hence:

25 = 4d/[tex]t_2[/tex]

[tex]t_2[/tex] = 4d/25 minutes

c) Since It took him 2 minutes longer to complete 4 laps backstroke than 4 laps breaststroke

[tex]t_2=t_1+2[/tex]

c)

[tex]t_2=t_1+2[/tex]

[tex]\frac{4d}{25}= \frac{2d}{25}+2\\\\multiply\ through\ by\ 25:\\\\4d = 2d +50\\\\4d-2d=50\\\\2d=50\\\\d=25\ meters[/tex]

The pool is 25 meters long
