Please help find the rate?!

Gwen, Tristan, and Keith like to work out at the gym. They each have an app on their phone that estimates the calories they burn

aleksandrvk [35]

Answer:

Part A:

Gwen has already burned 100 calories when Tristan and Keith started, and he continues to burn 10 calories per minute. The equation for Gwen is

y = 100 + 10x

Part B:

Tristan is burning 125 calories every 10 minutes. His burning calories rate is 12.5 calories per minute. The equation for Tristan is

y = 12.5x

Part C:

Keith is burning 300 calories in 30 minutes. His rate per minute is 10 calories per minute. The equation for Keith is

y = 10x

Part D:

Just follow the instructions and do the thing for the app. You can then answer the questions it is very easy.

Part E:

Do the same for E after you do Part D.

NEED HELP!!!!! ASAP THANK YOU SO MUCH!!!!! What figure is a dilation of Figure A by a factor of 3?

Fynjy0 [20]

Answer:

the figure on the top left

Step-by-step explanation:

Hey There!

If figure a was going to be dilated by a scale factor of 3 you would have to multiply all of its dimensions by 3

the top length would be 6

the bottom length would be 9

the right side length would be 12

and the left side length would be 9

The first figure has all of these dimensions thus it is correct answer

Solve through substitution –3x–8y=20 y=5x+19 Point of intersection, please

Sedaia [141]

Answer:

(-4, -1)

Step-by-step explanation:

-3x - 8y = 20; y = 5x + 19

y = 5x + 19; -3x - 8y = 20

y = 5x + 19

-3x - 8y = 20

-3x - 8(5x + 19) = 20

-43x - 152 = 20

-43x - 152 + 152 = 20 + 152

-43x = 172

-43x / -43 = 172 / -43

x = -4

y = 5x + 19

y = (5)(-4) + 19

y = -1

Employees salary [$}: 30,000, 30,000, 35,000, 35,000, 40,000, 40,000.

CEO Salary: $70,000.

The correct answer is this: BOTH JAN AND MARCY ARE CORRECT.

Jan says the employee average salary is $35,000. This is correct as shown below:

Average employee salary = 30,000 + 30,000 + 35,000 +35,000 + 40,000 + 40,000 / 6 = 210 / 6 = $35,000.

Marcy says the average salary of all company members is $40,000. This is also true as shown below.

Average salary of all company members = 30,000 + 30,000 +35,000 + 35,000 + 40,000 + 40,000 + 70,000 / 7 = 280 / 7 = $40,000.

Please help with this question I’ve been stuck on it if you can’t see click the picture it will make it a little bit bigger

Answer:

The option '$20 a month' is the correct option.

Step-by-step explanation:

The slope-intercept form of the line equation

$y = mx+b$

where

m is the rate of change or slope

b is the y-intercept

Given that Marta has opened a saving account with $25.

In other words, the initial condition of the function is $25.

Thus, the y-intercept b = 25

Let y be the total amount

Let x be the number of months

Given that at the end of three months, she has $85 in her account.

so we get the point (x, y) = (3, 85).

Now, in order to determine the rate of change or slope, substitute x = 3, y = 85 and b = 25 in the slope-intercept form of the line equation to determine the rate of change or slope

y = mx + b

85 = m(3) + 25

85 = 3m + 25

switch sides

3m + 25 = 85

subtract 25 from both sides

3m + 25 - 25 = 85 - 25

3m = 60

divide both sides by 3

3m/3 = 60/3

m = 20

so, the rate of change is $20 a month.

Thus, Marta has been making deposits at the rate of $20 a month to her savings.

Therefore, the option '$20 a month' is the correct option.
