Answer:

5/2 = 2.5

2/3 = 0.66667

Step-by-step explanation:

13) From graph

for A Constant of proportionality is 10/4 = 20/8 = 5/2 = 2.5

for B Constant of proportionality is 8/12 12/18 = 2/3 = 0.66667

14) for Object C unit rate / Constant of proportionality is

y / x = 7.5/5 = 15/10 = 30/20 = 1.5

unit rate = 1.5

Object C rate is in between A and B 's rate

A > C > B

Answer:

13)

Line A - slope/constant of proportionality = 5/2

Line B - slope/constant of proportionality = 2/3

14)

unit rate = 3/2 or 1.5

The unit rate, 3/2, is greater than line B's unit rate but is less than line A's unit rate.

Step-by-step explanation:

To find the constant of proportionality for question 13 you use the graph. k = y/x so you find the point at (4, 10) and you go up 10 (y) and over 4 (x). So now you have 10/4 and then you simplify to 5/2. Use the same method for line B to find the slope. Now for question 14 you subtract 10 - 5 to get 5 which is your x and 15- 7.5 to get 7.5 which is the y. So this is now 7.5/5 (y/x) or 3/2. 3/2 is less than 5/2 and greater than 2/3.

Thank you so much!!! Hope this helps!!!

2 degrees drop every hour, so 6 * 2 = 12

So, it would drop by 12 degrees after 6 hours.

Which description of the graph of y=110x is most accurate?

hodyreva [135]

Answer:

The correct option is;

The graph is a line that rises steeply from left to right and passes through the origin

Step-by-step explanation:

The given equation is y = 110·x

Comparing the given equation to the general equation of a straight line, y = m·x + c

Where;

m = The slope of the straight line graph

c = The y-intercept

We have;

The slope of the given equation, y = 110·x = 110

The y-intercept, which is given by the constant c in the given equation = (0, 0)

Therefore, by the slope of the equation, for each unit increase in x, y increases by 110, therefore, the graph is a straight line that rises steeply and passes through the origin

The Sommers invested $5000 for three years at 6.5%. How much interest did the investment earn in three years? What was the total

Jet001 [13]

Answer:

the interest is $975

the total amount is $5975

Step-by-step explanation:

lets use tje formula

I=PRT

where I is interest earned

P is the principal amount(original amount)

R is the rate of interest

and T is the time in years

the principal amount is 5000 since it is the original amount

rate is $\frac{6.5}{100}$ =0.065

time is 3 years

lets plug these values into our equation:

5000*0.065*3=I

5000*0.065*3=975

the interest is $975

the next part of the question is asking for the balance or the total amount which is principal+interest

5000+975=5975

the total amount or balance is $5975

hope this helps
