Answer:
Sarah mowed 1 lawn in 3 hours
Step-by-step explanation:
3 lawns divided by 3 is 1 lawn
9 hours divided by 3 is 3 hours
The segment marked 20 is the geometric mean of the two pieces into which it splits the hypotenuse. You get the proportion

Solving,

To find b, use the fact that b is the geometric mean of the whole hypotenuse, 21 + a, and the part that is attached to it, a.

A little arithmetic shows that

The triangle is equilateral. Given
<K = < M = 60 Property of an equilateral triangle.
IE = IE Reflexive property
Proof
- <IEK = <IEM = 90 Property of perpendicular
- <EIK = 180 - 60 - 90 All triangles have 180 degrees
- <EIK = 30 Subtraction
- <MIK = 180 - 60 - 90 All triangles have 180 degrees
- <MIK = 30 Subtraction
- <MIE = <KIE Both = 30 degrees
- IE = IE Reflexive property
- <IEK = <MEI Both are right angles.
- ΔMIK ≡ΔKIE ASA
The northbound car has traveled a distance of 6.2 miles.
Step-by-step explanation:
Step 1:
The eastbound car has traveled a distance of 5 miles and if a straight line is drawn between the two car's positions it would measure 8 miles.
This forms a triangle which has a hypotenuse measuring 8 miles while one of the other sides measures 5 miles.
Assume the distance traveled by the northbound car is x miles.
Step 2:
According to Pythagoras' theorem,


So the northbound car has traveled a distance of 6.244 miles. Rounding this off, we get 6.2 miles.
4 will be your answer
Explanation:
The factors of 12 are 1, 2, 3, 4, 6, 12
The factors of 88 are 1, 2, 4, 8, 11, 22, 44, 88.
So, as we can see, the Greatest Common Factor or Divisor is 4, because it is the greatest number that divides evenly into all of them.
hope it helped :D
