The number of water bottles used during a teams football practice varies directly with the temperature. If a team uses 75 water

bottles when the temperature is 60 degrees, what is the temperature if they use 120 bottles?

Supposing the temperature of 60 degrees increases twice, it becomes 120  degrees (100% increase) and the bottles increase twice as well to 150 bottles (100% increase). 

If there are 120 bottles used, we can calculate the temperature using the above assumption when bottle usage increase to 100% which is 150 bottles. 

120 bottles/ 150 bottles = 0.8 or 80%

So, if 100% increase in temperature is defines by 120 degrees, what is 80% of 120 degrees?  

Then 120 degrees divided by 0.8 will result to 96 degrees (so the answer is letter D) -- the temperature when 120 bottles were used by athletes.

Before recess, Marcy has math class for 1 hour and 50 minutes. Recess lasts for 30 minutes and ends at 11:55 A.M. What time does
Temka [501]

Answer:

Marcy's math class starts at 9:35.

Step-by-step explanation:

11:55

 -50  = 11:05     This gets rid of 50 minutes of math class.

11:05

  -30 = 10:35     This gets rid of the 30 minutes of recess.

Now subtract one more hour to subtract the remainder of math class, and you get 9:35. Marcy's math class starts at 9:35.

What is the equation of a line with a x-intercept of −2 and a y-intercept of 10?
IceJOKER [234]

Hey there! :)

Answer:

y = 5x + 10

Step-by-step explanation:

From the information given, we can derive the points (-2, 0) and (0, 10). Find the slope using the slope formula:

m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}

Plug in the points:

m= \frac{10 - 0}{0 - (-2)}

Simplify:

m= \frac{10}{2}

m = 5.

The equation in slope-intercept form is y = mx + b. We were already given the b value, or y-intercept as y = 10. Therefore:

y = 5x + 10 is the equation written in slope-intercept form.

Help pls look at the picture
Alika [10]

Answer:

Option A: -\frac{4}{3} is the correct answer.

Step-by-step explanation:

Given that:

Slope of the line = \frac{3}{4}

Let,

m be the slope of the line perpendicular to the line with slope \frac{3}{4}

We know that,

The product of slopes of two perpendicular lines is equals to -1.

Therefore,

\frac{3}{4}.m=-1\\

Multiplying both sides by \frac{4}{3}

\frac{4}{3}*\frac{3}{4}m=-1*\frac{4}{3}\\

m = -\frac{4}{3}

-\frac{4}{3} is the slope of the line perpendicular to the line having slope \frac{3}{4}

Hence,

Option A: -\frac{4}{3} is the correct answer.
