Answer:
10n -11 =3 + 4n + 6n
10n - 10n -11 =3-3 + 4n + 6n
-11 - 3 = -10n + 4n + 6n
-14= -10n + 10n
-14 = n
Step-by-step explanation:
10n -11 =3 + 4n + 6n
10n - 10n -11 =3-3 + 4n + 6n
-11 - 3 = -10n + 4n + 6n
-14= -10n + 10n
-14 = n
Answer:
1/4
Step-by-step explanation:
First, add up the marbles:
2 + 9 + 7 = 18
Multiply by 2 because you pick two:
18 × 2 = 36
Simplify:
9/36 = 3/12 = 1/4
Hope this helped.
Answer:
wut thut u better tell me -_-
Step-by-step explanation:
Step-by-step explanation:
For oil container in the shape of a cylinder
radius (r) = 6 m
height (h) = 7 m
TSA of Cylinder
= <em><u>2πr ( r + h) </u></em>
= 2 * 3.14 * 6 ( 6 + 7)
= 2 * 3.14 * 6 (13)
= 2 * 3.14 * 6 * 13
= 489.84 square meter
<em>Now, </em><em> </em>
the total cost of the steel will be $18,613.92.
= 18613.92/489.84
= $38
Thus, The TSA of a cylinder is 489.84 square meter and $38 will the steel cost per square meter.
