The answer is not on the list the answer is 90,522 and that is not up on the list
Good question i just can't figure it out!
She went over by 1/6 of a cup because 64 is half of 128 and 2/3 is greater then 1/2
<em>solution</em>
<em> time taken=100secs</em>
<em> distance covered=500m=0.5km</em>
<em>As we know,</em>
<em> speed=distance covered/time taken</em>
<em> =0.5km/100secs</em>
<em> =0.005km/sec</em>
<h2>
<em> </em></h2><h2>
<em> SPEED IS 0.005KM/SEC</em></h2>
Answer:
- shortest: 3 ft
- other: 4 ft
Step-by-step explanation:
The right triangle with hypotenuse 5 that has legs that differ by 1 is the 3-4-5 right triangle. The legs are 3 ft and 4 ft.
__
<em>Alternate solution</em>
If you have never heard of a 3-4-5 right triangle, you can figure the leg lengths algebraically using the Pythagorean theorem. Let x represent the length of the "other" leg. Then the shortest is (x-1). The Pythagorean theorem tells you ...
5^2 = (x)^2 +(x -1)^2
25 = 2x^2 -2x +1
12 = x^2 -x = x(x -1)
Factors of 12 that differ by 1 are 3 and 4 or -3 and -4. We want x to be positive, so the value of interest is x=4
The "other" leg is 4 ft; the shortest leg is 3 ft.
