Answer:

145 degrees.

Step-by-step explanation:

Because the lines are the same length on each half we know that the corner opposite to the right angle is also a rangle. In a quadrilateral (4 sided shape) the angles should add up to 360 degrees. We now have the total as x + 35 + 90 + 90 = 360 which when rearranged gives x = 145 degrees.

Mitch and Delilah both drove 500 miles. Mitch averaged 60 miles per hour. Delilah averaged 65 miles per per hour. How muc longer
sergejj [24]
First, we need to figure out how long it took Delilah to travel 500 miles.  We can do this by dividing 500 by 65.  This is equal to 7.69 hours, or 7 hours and 41 minutes.

Next, we figure out how long it took Mitch to drive 500 hours.  We do this the same way: divide 500 by 60.  500/60 = 8.33 hours, or 8 1/3 hours.

We finish this problem by subtracting 7.69 from 8.33.  This is equal to 0.64 hours, or 38 minutes.  So, it took Mitch 0.64 hours or 38 minutes longer than Delilah to drive 500 miles.

Which fraction is between 0 and 1/2
faust18 [17]

The Fraction that is between 0 and 1/2 is 2/10

The fraction 1/2 can also be written as 5/10. If you were to make a number line, you would be able to see that 2/10 is between. Here, let me order them from least to greatest:

< - 0 - - 2/10- - - 1/2- - 7/10- 3/4 - 8/10 - >

As you can see, 2/10 is between 0 and 1/2 (5/10).
