Do you need to switch it around or do something else?

In y=mx+b format the equation is y=1/2x-4. you need to mark -4 on your graph then go up one unit then over two units. then continue to go up 1 over 2 until you get your line

Find the geometric mean of 25 and 100.<br> A. 50<br> B. 62.5<br> C. 1250<br> D. 2500

Debora [2.8K]

<h3>Answer: Choice A) 50</h3>

For two numbers x and y, the geometric mean is G = sqrt(x*y)

In this case, x = 25 and y = 100, so

G = sqrt(x*y)

G = sqrt(25*100)

G = sqrt(2500)

G = 50

Round to the nearest hundredth 5/8

Solnce55 [7]

Eighths and their multiples are common fractions which I recommend memorizing, but to actually solve this, you use the literal meaning of a fraction and divide 5 by 8. See the long-division below (it was surprisingly difficult to type, so I hope it helps!).

To round 0.625 to the nearest hundredth, we go to the second decimal place, which is 5, so we round up to 0.63.
