Answer:
3 : 2
Step-by-step explanation:
To determine the scale factor.
Calculate the ratio of diameters or heights, that is
18 : 12 = 3 : 2 ← using diameters
30 : 20 = 3 : 2 ← using heights
Answer:
(x - 2) and (x + 3) is a factor of: 2x² + 2x - 12
Step-by-step explanation:
2x² + 2x - 12 given equation
Now divide it by 2 we get,
x² + x - 6
then
x² + x - 6
x² + 3x - 2x - 6
x(x + 3) - 2(x + 3)
<em><u>(x - 2) (x + 3)</u></em>
-3/8 -1/10 = (-15 -4)/40 = -19/40
so this mean that choice D. is right sure
hope this will help you
Answer:
a) 68
b)60
Step-by-step explanation:
a) 85% = 0.85
0.85 * 80 = 68
b) let x be the unknown number.
35% = 0.35
0.35x = 21
x = 60
9^2 = 81
9^7 = 4,782,969
\frac{81}{4,782,969}
