Step-by-step explanation:

to find the volume of a cone the equation that you are going to use is:

[tex]V=\pi r^2 \frac{h}{3}[/tex]

Step 1: Plugin

[tex]V=\pi 2^2 \frac{8}{3}[/tex]

Answer:

Alexander sold

8 tickets on Tuesday

16 tickets on Wednesday

7 tickets on Thursday

Step-by-step explanation:

Let us represent:

Number of tickets sold on Tuesday = a

Number of tickets sold on Wednesday = b

Number of tickets sold on Thursday = c

In three days Alexandra sold a total of 31 tickets to her school play.

a + b + c = 31...... Equation 1

On Tuesday she sold as twice as many tickets as on Wednesday.

2a = b

And on Thursday, she sold exactly seven tickets.

c = 7

Substitute 2a for b and 7 for c in Equation 1

a + b + c = 31...... Equation 1

a + 2a + 7 = 31

3a = 31 - 7

3a = 24

a = 24/3

a = 8 tickets

Note that

2a = b

a = 8 tickets

2 × 8 = 16 tickets

b = 16 tickets

Therefore, Alexander sold

8 tickets on Tuesday

16 tickets on Wednesday

7 tickets on Thursday

Step-by-step explanation:

3 3 3

Answer:

3

Step-by-step explanation:

4x – 2y=7

3x – 3y = 15

we want to keep y by eliminating the x

so we will Multiply the top equation by 3 and the bottom equation by 4.

we will get

12x - 6y = 21

12x - 12y = 60

we subtract the equations

12x - 6y - 12x - (-12y) = 21 - 60

6y = -39 and so on

Look a the picture.

Draw the horizontal line y = 2.

Common point: (-4, 2).

Conclusion: f(x) = 2 → x = -4

From the graph at x = -4, then value of f(x) will be 2.

A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner.

In the given graph, first we have to draw a line f(x)=2 i.e y=2

Draw the horizontal line y = 2.

We have to check where the horizontal line is meeting the line in graph.

Then we get a Common point at (-4, 2).

So x value is =-4 for f(x)=2 in the given graph.

The true statement is that, the probability that 17% to 23% percent of all voters planned to vote is high

The percentage sample error (S) is given as:

S = 3%

The proportion (p) of the respondent is given as:

p = 20%

This means that the range (R) of the proportion is:

R = p ± S

This gives

R = 20% ± 3%

Expand

R = (20% - 3%, 20% + 3%)

Evaluate

R = (17%, 23%)

Answer:amount of decrease 290 ;numbers of chairs 5510

Step-by-step explanation:

Stablish the proportion 5800/100%=x/5% then solve for x. ; x=(5%/100%)*5800 = 290 which is the decrease. Then make the difference 5800-290 and you get 5510

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

The number of chairs decreased is 290.

The number of new chairs produced each month is 5510.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

We have,

Number of chairs produce in a month = 5800

5% decrease in production:

= 5% of 5800

= 5/100 x 5800

= 5 x 58

= 290

The number of new chairs produced each month:

= 5800 - 290

= 5510

Thus,

The number of chairs decreased is 290.

The number of new chairs produced each month is 5510.
