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.

True, but not many. Insurance companies typically have a cap off so the client doesn't go in let's say every week for a check up to see if they grew an inch. This is form personal experience in reading into the fine print.

A researcher is interested in the effect of alcohol consumption on reaction times. Participants are assigned to one of three pos

IRINA_888 [86]

Answer:

The three different possible conditions ;

nonalcoholic beer group, 1 beer group, 2 beer group

Step-by-step explanation:

The Independent variable, also known as the predictor variable are variables used to influence and check changes in the dependent or predicted variable as subjects are exposed to the different types or levels of independent variable used in the study.

In the scenario described above, the predictor or independent variables which are used to measure the reaction times of participants to unexpected variables is the independent variable, beacuse these different variables ; nonalcoholic beer, 2 beer will probably affect the response time of the participants which is the dependent variable.

Anna007 [38]

Answer:

The sound intensity of a whisper is 333.3 times the reference intensity

Step-by-step explanation:

Given : The function $y = 10logx$ gives the intensity of a sound in decibels, where x is the ratio of the intensity of the sound to a reference intensity.
