Answer:

12 minutes

Step-by-step explanation:

You subtract 13.68 from 15 which gives you 1.32 which you then divide by .11 since it was eleven cents per minute on the phone and you end up getting 12.

If m is the midpoint of segment JK, JM equals 7x minus 32, and MK equals 89 minus 4x, what is MK?
KonstantinChe [14]

Step-by-step explanation:

Imagine this segment, given that m is the midpoint of segment JK...

      J________M________K

   JM = 7x-32        MK = 89 - 4x (given)

If m is the midpoint, then JM and MK are the same lengths (equal to each other). We can use that to first find what <em>x</em> is.

7x -32 = 89 - 4x\\

Steps to find x (we have to get x by itself):

7x - 32 + 4x = 89 - 4x  +4x

11x -32 = 89

11x -32 +32 = 89 +32

11x = 121

\frac{11x}{11} = \frac{121}{11}

x=11 (we haven't found the answer yet! we only found x)

Now that we found x, we can find segment MK. Now we know that:

MK = 89 - 4x  

x= 11

Let's plug x into the equation:

MK = 89 - 4(11)\\MK = 89- (44)\\MK = 45

Answer: MK= 45

Whoever wants to help me out please do so. I need all the help I can get.
klio [65]

Answer:

68

Step-by-step explanation:

Angle R is 124 which also makes angle FDE 124 because they are opposites which make them congruent. To find angle FDA you can make the equation 124 + ? = 180 then you subtract 124 from 180 to get 56 which is your FDA.

Since you know angle FDA and angle DAF are congruent you know that DAF is also 56. Then you multiply 56 by 2 (because 2 angles are 56) to get 112 and subtract that from 180 to get 68. That is your angle DFA

A flower vendor sells roses for 50 cents each. How much does she pay per flower is she makes $6.00 on every twenty dollars worth
Lelu [443]

One rose is 50 cents, so 2 roses cost $1 ( 50 cents x 2).

2 roses per dollar x 20 dollars = 40 total roses sold.


When they sell $20 dollars they make $6, so that means they pay 20-6 = $14 dollars for the 40 roses.


$14 / 40 roses = 0.35 per rose.

She pays 35 cents per rose.
