Answer 3

Jerry types 71 words per minute.

a.Write an equation to determine the amount of time it would take to type a given number of words. Define your variables.
b.How long would it take Jerry to type 2556 words?
c.If Jerry typed for 20 minutes, how many words did he type?

Answer 4

A) Think about what 71 words per minute means. It's a rate. For every minute, you will have typed 71 words. So to say how many minutes it will take you to type 71 words, you can say that the total number of words divided by the rate will give you the time. So you have T=W/71 where T is the total amount of time and W is a given total amount of words.

B) If we use our equation, we have T=2556/71=36, so it will take Jerry 36 minutes to type 2556 words at a rate of 71 WPM.

C) Again, using our equation, we have 20=W/71 which when we multiply by 71 on both sides, we'll get 1420=W, so Jerry would've typed 1420 words in 20 minutes if he typed at a rate of 71 WPM.

Hopefully, this helped you understand slopes and rates better.

Answer 9

The graph shows the relationship between the distance a professional biker is traveling and the time in hours.

A graph is shown in the xy-plane. The x-axis is labeled as Time in minutes and the y-axis is labeled as Distance in miles. The values on the x-axis ranges from 0 to 10 in increments of 1 and the values on the y-axis ranges from 0 to 4 in increments of 0 decimal point 5. A line starts from the origin and goes up. Five points are marked on the line. For 1 on the x-axis the value of y is just below 0 decimal point 5 on the line, for 2 on the x-axis the value of y is just above 0 decimal point 5 on the line, for 5 on the x-axis the value of y is between 1 decimal point 5 and 2 on the line, for 8 on the x-axis the value of y is just below 3 on the line, and for 10 on the x-axis the value of y is 3 decimal point 5.

a. Define variables and write an equation to represent the relationship between the quantities.
b. How far would the biker travel in 20 minutes?
c. If the biker traveled 48 miles, how many minutes did he bike? Round to the nearest tenth

Answer 10

I'm sorry, but without an actual picture of the graph, it's not very easy to help you out. Unfortunately, you can't post a URL of the graph here either, so that's not helpful.

Answer 11

I can answer other questions though that don't require a picture

Answer 12

ok thx

Answer 13

The cost of a small cup of coffee at a deli is $3.50. You can use the equation

t
=
3
.
5
n
, where t represents the total money made from the sale of small coffees and n is the number of cups of small coffees sold. In this equation, which describes the role of n?

A.
the dependent variable

B.
the independent variable

C.
the dependent quantity

D.
the independent quantity

Answer 14

A) The dependent variable is the effect that occurs from the cause (independent variable). In this case, since y=kx means y varies directly with x by a factor of k, then t=3.5n means t varies directly with n by a factor of 3.5, making t the dependent variable

B) The independent variable is the cause that impacts the effect. So n would be your independent variable because it's not impacted unless you impact it which in turn will impact the effect.

C) In terms of quantity, we already said t is the dependent variable, so the total money made would be the dependent quantity because "depending" on how many coffees you sell, the value changes.

D) This time it's n, the amount of coffees you sell. This will impact how much total money you will make.

Answer 15
