Contestants in a dance-a-thon rest for the same amount of time evey hoir. A couple rests for 25 minutew in 5 hours. How long did
Semenov [28]

If each couple rests for k minutes every hour, the time spent resting, r, after h hours is given by

r = kh

We know that a couple spent 25 minutes resting in 5 hour. So, the rate is

25 = 5k \iff k = \dfrac{25}{5}=5

So, every couple rests 5 minutes per hour.

This means that, after 8 hours, the couples rest

r = 5\cdot 8 = 40

minutes.

D. Not enough info

Angles N and P are supplementary (125º + 55º = 180º) but this doesn't tell us anything about the measures of angles M and Q. The edge MQ of the quadrilateral is not guaranteed to be parallel to NP.

For example, we can move vertex M anywhere along MN and still preserve the measures of angles N and P.

Multiply. Express in simplest form. 3/8 x 1/2
CaHeK987 [17]

Answer:

the answer is 3/16.

Step-by-step explanation:

First, let's take a look at the expression itself.

We have to multiply 3/8 and 1/2, which gives us the expression of

3/8*1/2

then, we multiply the numerator by the numerator and get 3, then we multiply the denominator by the other denominator which gets us 16. We put the two parts together and get

3/16

which is not simplifiable. So 3/16 is the simplest answer we can get.
