Answer:
11 grades of 85 did Brenda, Robert, and Timothy receive altogether.
Step-by-step explanation:
Let 6x be the number of 85 received by Brenda.
The number of 85 received by Robert is 1/3 of Brenda= 2x
The number of 85 received by Timothy is 1/2 of Brenda= 3x
Then according to the given conditions
6x+ 2x+ 3x
= 11x
So the number of total 85s received by all the three is 11.
11 grades of 85 did Brenda, Robert, and Timothy receive altogether.
The solution is negative.
Just incase u need the work. Its C.
Area of entire circle = (pi)(r^2) and r = d/2:
<span>A =(3.142)((3.2^2) = 32.17m^2 </span>
<span>Portion of circle in sector: </span>
<span>185degrees/360degrees = 0.514 </span>
<span>Multiply: </span>
<span>0.514(32.17m^2) = 16.5m^2 to 1 dp </span>
0.39 inches.
Or 0.4 if you want to round it ;3
