Answer:
36 hours.
Step-by-step explanation:
There is 24 hours in a day therefore,
24 x 3 = 72 This is how many hours are in 3 days
72 ÷ 2 = 36 Therefore there are 36 hours in 3 1/2 days
Hope this helps.

<span>If you want to convert 15.1 into a fraction, you can do it like this:
15 <span>equals to 15</span>/1 <span>and </span>0.1 <span>equals to 1</span>/10
<span>The result is 15</span> 1/10.
If you want to make it a pure fraction, you have
to make one additional step:
<span>because you want to add 15/1 and 1/10, you
have to get the same denominators, so 15/1 changes to 150</span>/10.
<span>Now, you can add </span>150/10 and 1/10<span>.
The result is </span>151/10<span>.

Answer:
<em>The circle has a radius of 41 inches</em>
Step-by-step explanation:
<u>Circles</u>
There are certain relations in a circle that help us to identify and calculate some of its characteristics.
The figure shows a circle with three parameters which will lead us to determine its radius. First, we have a chord that measures 80 inches. Since it doesn't go through the center of the circle, it's not the diameter.
But we also have the distance from the center to the chord, making a right angle with it. This makes the chord be divided into two equal parts of 40 inches each.
Now we form a right triangle joining the center to one of the extremes of the chord. The hypotenuse of this triangle is the required radius of the circle. Like every right triangle, this must comply with Pithagora's theorem:

where r is the hypotenuse and x, y are the legs or the smaller sides of the triangle. We have determined that x=9, y=40 (or vice-versa, it doesn't matter). Therefore

Solving for r

The circle has a radius of 41 inches
Answer:
5 Laps
Step-by-step explanation:
The question says that she runs the same distance everyday. This shows us that...
2 laps on a running trail and 6 more miles = 4 laps on a running trail and 2 more miles
We can turn laps into the variable L and miles into the variable M to create an equation
2 L + 6 M = 4 L + 2 M
We can start by subtracting 2 M from both sides to get:
2 L + 4 M = 4 L
Now, we can subtract 2 L from both sides
4 M = 2 L
This tells us that 2 laps are 4 miles which means that 1 lap is 2 miles.
Now, we can break down either side of the equation. Let's break down
2 L + 6 M
First, we can turn the miles into laps. We know that 2 miles is one lap so we can divide 6 by 2. Our Equation:
2 L + 3 L
Now, we can simplify this :
5 L
Now we know that she ran 5 laps on saturday.
