Answer:
Take the square roots of the numerator and denominator separately.
Explanation:


===============
If your instructor wants a decimal answer, take the square root of the numerator.

= 1.072
15 miles in 20 minutes.
there are 60 minutes in one hour.
Convert it from minutes to hour
Answer:
y - 7 = -1/4(x-4)
Step-by-step explanation:
point slope is y-y₁=m(x-x₁)
(4, 7) and (8, 6)
I like to put it in the slope-intercept form first
so... 6 - 7/ 8-4 = -1/4 (slope)
6 = -1/4(8) + b
6/(-2) = -2/(-2) + b
-3 = b
so... y=-1/4x + -3
plug it in to point slope form
y - 7 = -1/4(x-4)
hopefully that made sense :)
Answer:

Step-by-step explanation:
Isosceles triangles are a type of triangles in which two of their sides have an identical length. It should be noted that the angles opposite the sides that are the same length are also the same. This means that these triangles not only have two equal sides, but also two equal angles.
You can solve this problem using different methods, I will use pythagorean theorem. First take a look at the picture I attached. As you can see:

And we can find a easily using pythagorean theorem:

Solving for a:


Therefore:

See below
Step-by-step explanation:
<em>Compatible numbers</em> are numbers that are easy to use in mental arithmetic.
Martin gave away ⅖ of 7 lb of grapes, so the amount he gave away was
⅖ × 7 lb
⅖ is close to ²/₄ (½), and it is easy to take half of something mentally.
Half of 7 is about 3, so Martin gave away about 3 lb of grapes (the exact answer is 2.8 lb).
