the volume of the cone is 25.12 the height is 6 what is the area of the base​

Answers

Answer:

153.94

Step-by-step explanation:

AB=πr2=π·72≈153.93804

Answer:

The area of the base is 12.56 units squared.

Step-by-step explanation:

The volume formula of a cone is [tex]\pi r^{2} \frac{h}{3}[/tex]. To solve for the base area, just multiply the volume by 3 and divide by the height. 25.12 * [tex]\frac{3}{6}[/tex] = [tex]\frac{25.12}{2}[/tex] = 12.56 units squared.

The mean of a set of numbers is 8, and the mode is 9.

Which of the following sets of numbers do these values describe?

3, 7, 9, 9, 10, 14
1, 5, 8, 10, 11, 13
4, 6, 8, 9, 9, 12
3, 5, 7, 9, 12, 12

Answers

You can start by looking at the mode of the set of number automatically b and d are eliminated. We then proceed to calculate the mean so add all the numbers in A so it’ll be, 52 then divide by the amount of numbers in the set so 6. 52/6 =8.6
And C ends up being 48 so 48/6 = 8
Therefore your answer is C

Rotated clockwise: 6,-4
Rotated counter clockwise: -6,4

Answer:

(6,-4)

Step-by-step explanation:

when you have (x,y) and you want to rotate it 90 degrees, you would switch the x and the y and then make the x negative. So (4,6) would switch to (6,4) and then the 4 would become negative.

A traffic camera sits on top of a tower that has a height of 39 ft. The angles of depression of a car on a straight road at the same level as that of the base of the tower and on the same side of the tower are 31°. Calculate the the distance between the base of the poll and the car. Round to the nearest tenth of a foot. *

Answers

Answer:

48ft

Step-by-step explanation:

Distance of car A from the towerConsider ∆ACD tan25 = 50/AC AC  = 50/tan25 = 50/0.4663 = 107.2 ft Distance of car B from the towerConsider ∆BCD tan40 = 50/BC AC  = 50/tan40 = 50/0.8391 = 59.6 ft

Distance from cars A and B AB = AC – BC = 107.2 – 59.6 = 48 ft The distance between the two cars is 48ft

Here is a scatter plot that compares points per game to free throw attempts per game for basketball players in a tournament. The model, represented by y=4.413x+0.377, is graphed with the scatter plot. Here, x represents free throw attempts per game, and y represents points per game.

What does it mean for a point to be far above the line in this situation?

Answers

Answer:

Point above the line is an outlier

Step-by-step explanation:

If the point is above the given line then it is clear that it does not fit the best fit curve (which is in this case is the line represented by equation y=4.413x+0.377)  

Point above this line means that the point is an outlier which does not fit the curve.

How many grams are 7.00 x 1022 molecules of NaOH?

Answers

Answer:

46.5

explanation

6.022*10^23 molecules=40g.

7.00*10^23=40*7.00*10^23/6.022*10^23 g =46.5 g

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 4.65g  are  7.00 x 10²²  molecules of NaOH.

What is mole?

The mole is used to measure the quantity of amount of substance. It measure the number of elementary entities of a given substance that are present in a given sample.

we know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number

mole =given number of atoms ÷ 6.022×10²³(Avogadro number)

given number of atoms of NaOH= 7.00 x 10²² atoms

Substituting the values

mole=7.00 x 10²²÷ 6.022×10²³

mole =0.116 moles of NaOH

mass of NaOH= Molar mass of NaOH× moles of NaOH

= 40 × 0.116

= 4.65g

Therefore, 4.65g are  7.00 x 10²²  molecules of NaOH.
