Answer:
Step-by-step explanation:
Alternate exterior angles lie on the outer part and are opposite each other
4 and 6
1 and 7
Since the triangles are congruent the angles given are the same. If we know triangles have 180 degrees total within their angles then 44 + 55 - 180 = 81 degrees. Z=81
65.5$ divided by 3 equals 21.83$ or aka 21.83 per sweatshirt ( 21.83:1)
We'll have to add up all the fractions.
First, find the LCM of the denominators.
To do this, we'll use the listing method.
4: 4, 8, 12, 16, 20, 24, 28, 32, 36, all the way to 140.
5: 5, 10, 15, 20, 25, 30, 35, all the way to 140.
7: 7, 14, 21, 28, 35, 42, 49, all the way to 140.
So, 140 is the Least Common Multiple.
Multiply the numerator of 1 as many times you multiplied 4 to get to 140, which is 35.
1 x 35 = 35.
Multiply the numerator of 2 as many times you multiplied 5 to get to 140, which is 28.
2 x 28 = 56
Multiply the numerator of 3 as many times you multiplied 7 to get to 140, which is 20.
3 x 20 = 60.
So: 35/140 + 56/140 + 60/140
=35/140 + 116/140
=151/140
=1 11/140
So, the swimmer swam 1 and 11/140th of a mile.
