Answer:
10 = c
Step-by-step explanation:
Distribute -4 to the parentheses:
8 = 8c - 4(c + 8)
8 = 8c - 4c - 32
Add like terms:
8 = 4c - 32
Add 32 to both sides:
40 = 4c
10 = c
Step-by-step explanation:
Radius is same in both cones....
Slant height of lower cone = 50 cm ( by applying Pythagorean theorem )
TSA of the lower cone = 22/7 × 14 × ( 14 + 50 )
= 2816 cm^2
Total height of the solid = 52.8 cm
Height of the upper cone = 52.8 - 48 = 4.8 cm
TSA of the upper cone = 22/7 × 14 × ( 14 + 4.8 )
= 827..2 cm^2
TSA of the solid = 2816 + 827.2 = 3643.2 cm^2

Answer:</h3>
<em>The theoretical probability to draw a black marble is </em><u><em>0.23</em></u><em>. </em>
Step-by-step explanation:
First add up the total amount of marbles in the bag.
14 gray marbles + 7 black marbles + 10 white marbles = 31 total marbles.
Since we need the odds of a black marble being drawn, divide 7 (the amount of black marbles) by 31 (the amount of total marbles).
7/31 ---> 0.22580645161 <u><em>(it is easiest to use a calculator on this step)</em></u><em> </em>
Lastly, round the decimal to the nearest hundredth.
0.22580645161 ---> <em>0.23</em>
<em>0.23</em> would be the odds of drawing a black marble.
