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

NEED HELP PLEASE!!!

zimovet [89]

Variables:
p = uniform pants
c = baseball caps

Equations:
$2p + 2c = 68$
$p - c = 12$
****************************************************************************************
Step 1.
$\left {{2p+2c=68} \atop {p-c=12}} \right$

Step 2.
$\left {{2p+2c=68} \atop {2(p-c=12)}} \right.$

Step 3.
$\left {{2p+2c=68} \atop {2p-2c=24}} \right.$

Step 4.
$4p = 92$

Step 5.
$\frac{4p}{4} = \frac{92}{4}$
$p=23$

Step 6.
$p-c=12$
$23 - c=12$
<u /> $23=12+c$
<u /> $11=c$
<u />
Baseball Pants = $23
Baseball Caps = $11
