Answer: To find the answer for question 7 we would first need to find the volume of the cylinder as a whole.  To find a cylinders volume all you need to do is input values into this formula V=πr2h.  In our case the volume is 508.94.  Now we would need to subtract out the volume of the cone that was carved out.  To find the volume of a cone use this formula, V=πr2h /3.  The volume of the cone is 113.1.  Now subtract 113.1 from 508.94 to get 395.84 which rounds to 396 in cubed.  This means that B) is your answer.  Now for question #11.  This is quite similar to the other problem but this time it involves adding a cone and cylinders volume together instead of subtracting them.  Follow the same steps as before except add instead of subtract.  The volume of this cylinder is 1017.88.  The volume of the cone on top is 37.7.  Add these two values together to get 1055.58 which is your answer.  As for the last one which is question #4 which asks us to solve for the angle all we would need to do is find out what x is equal to and then input that into the equation given for angle Q and solve!  To solve for x follow these steps.  (11x -5)+(6x+5)+(x)=180  Set the equations for each angle equal to 180 as that is the sum of all angles in all triangles.  Then solve for x.  We get that x = 10.  Now plug in x = 10 into the equation for angle Q. 11(10)-5=105.  This means that angle Q is 105 degrees.

What is the future value of $845 a year for seven years at an interest rate of 11.3 percent? $6,683.95 $6,075.69 $8,343.51 $8,00
k0ka [10]
The future value of cash whose initial value is $845, at the rate of 11.3% for 7 years will be calculated using the compound interest rate, that is:
A=p(1+r/100)^n
where:
A=future amount
r=rate=11.3%=0.113
time=7 years
thus the future value of our cash will be:
A=845(1+0.113)^7
A=845(1.113)^7
A=$1,787.82

The graph below shows the annual cost (green) and sales (red) of a company. What is the break-even point?
s344n2d4d5 [400]

The break-even point for the graph is at 11 units.

Step-by-step explanation:

Break-even point refers to the point on the graph where either of the parameters of the graph intercepts each other. The corresponding location of the position where the intersection occurs gives the break-even point.

In the graph annual cost is plotted in green on the Y axis, while the sales are plotted on x-axis in red.

When we observe the graph carefully, we find that two-line intercepts. When the point at which interception occurs is extended on the x-axis, the point is 11 units, which gives us the break-even units.

Hence the point is 11 units.
