Answer:

Rick ran 5.6 miles on Thursday.

Step-by-step explanation:

Let's first find the speed Rick ran on Wednesday.

D=RT

4.2 = (3/4)R

R = 5.6 mph.

D=RT

D=(5.6 mph)(1)

D=5.6 miles

Let me know if this helps!

Which graph best represents the equation created when the slope of y = 6x is changed to 0?
luda_lava [24]

The graph with an equation y = 6x has a slope of 6. If the slope is changed to 0, the equation becomes y = 0.

<h3>What is a linear function?</h3>

A linear function is in the form:

y = mx + b

Where m is the slope (rate of change) and b is the y intercept

The graph with an equation y = 6x has a slope of 6. If the slope is changed to 0, the equation becomes y = 0.

The ratios of the measures of the angles in a triangle is 3:10:7. Find the measure of the smallest angle. Just write the numeric
Burka [1]
Answer to written question:
3x + 10x + 7x = 180
Combine like terms
20x = 180
Divide by 20
x = 9
Smallest angle 3x = 3*9 = 27 degrees

Answer to question in picture:
30/6x-2 = 36/5x + 13
Cross multiply
30(5x + 13) = 36(6x-2)
Distribute
150x + 390 = 216x - 72
Subtract 150x
390 = 66x - 72
Add 72
462 = 66x
Divide by 66
x = 7

Since insulin u-100 is 100 units/mL,which of the following shortcuts can be used to convert a dose of u-100 insulin given in uni
N76 [4]

Answer:

The shortcuts is

     Divide number of units by 100

Step-by-step explanation:

From the question we are told that

  insulin u-100 is  L  =  100 \ unit /mL

 From the data given above we see that

           100 units of  insulin u-100 is contained in  1 mL

So         1 unit of  u-100 is contained in  x mL

=>       x =  \frac{1}{100} \  mL

This means that a unit of  insulin u-100 occupies  x =  \frac{1}{100} \  mL

So we can represent a single unit of insulin u-100 as  \frac{1}{100} \  mL

  Now if 1 unit of insulin u-100 is represented  as    \frac{1}{100} \  mL

Then y unites of   insulin u-100  is represented as  z

So

         z = \frac{y}{100}  \  mL

From the above calculation we can see that the shortcuts to convert  u-100 insulin given in units, to mL is to  divide  number of units by 100
