The price of the advance ticket is  $40 and the price of the same day tickets is $30.

a + b = $70 equation 1

20a + 35b = 1850 equation 2

Where:

a = cost of one advance ticket

b = cost of one same day ticket

Multiply equation 1 by 20

20a + 20b = 1400 equation 3

Subtract equation 3 from equation 2

15b = 450

Divide both sides by 15

b = $30

Subtract $30 from $70.

$70 - $30 = $40

People leaving the library were asked how many books they checked out that day The result are: 1,2, 3, 5, 8, 9, 10, 11, 12, 13, 14, 15, 16, 18, 20

To Find:

Which histogram correctly shows the data set?

Solution:
Since it given from the histogram:

0-5, 6-11, 12 - 17,18-23

From the result :

1,2, 3, 5, 8, 9, 10, 11, 12, 13, 14, 15, 16, 18, 20

Thus,

1,2,3,5 = 0-5

8,9,10,11 = 6-11

12,13,14,15,16 = 12-17

18,20 = 18-23

From this we can see that:

for

0 - 5 = 4

6 - 11 = 4

12 - 17 = 5

18 - 23 = 2

Hence, the answer is [B]

Answer:

180° = pi radians

Step-by-step explanation:

360° = 2pi radians

90° = pi/2 radians

see image

180° is pi radians.

pi radians is equivalent to 180 degrees, option B is correct.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

The radian equivalent of 180° is pi radians.

This is because a full circle is 360°, which is equivalent to 2 pi radians. Therefore, half of a circle or an angle of 180° is equivalent to half of 2 pi radians, which is pi radians.

Hence,  pi radians is equivalent to 180 degrees, option B is correct.

Answer:

31

Step-by-step explanation:

PEMDAS is Parentheses, Exponent, Multiplication, Addition, Subtraction

This is just the order you do the operations.

First, Parentheses.

Second, Exponents,

Third, Multiplication or Division

Last, Addition or Subtraction

So we have,

[6(20) + 3(15)] ÷ 5

We first look at Parentheses.

The first case is 6(20)

6(20) = 120

We have [120 + 3(15)]÷ 5

We solve 3(15) as its the next parentheses

3(15) = 45

We have [120 + 45] ÷ 5

Then we solve for [120 + 45] as it's in brackets.

[165] ÷ 5 = 31

The answer is 31.

Answer:

Below.

Step-by-step explanation:

7(x + 2) = 91

Distribute the 7 over the parentheses:

7x + 14 = 91

Subtract 14 from both sides of the equation:

7x = 91 - 14

7x = 77

x = 77/7 = 11.

Answer:

X=11

Step-by-step explanation:

[tex]7\left(x+2\right)=91[/tex]

Divide both sides by 7:

[tex]\frac{7\left(x+2\right)}{7}=\frac{91}{7}[/tex]

Simplify:

[tex]x+2=13[/tex]

Subtract 2 from both sides:

[tex]x+2-2=13-2[/tex]

Simplify:

X=11

[tex]\implies f(4) = 5f(3)+4=5(49)+4=249[/tex]

Answer:The equations representing the lines that are perpendicular to line m are:

B. y = -2/3x +4

E. y+1=-4/6(x+5)

Step-by-step explanation:Lines that are perpendicular to each other have slopes that are negative reciprocal of each other.

For example, if a line has a slope of 2, the slope of a line that is perpendicular to it would be, -1/2 (negative reciprocal of 2).

Determine the slope of the given line whose equation is, y + 2 = 3/2(x + 4). Rewrite the equation in slope-intercept form [y = mx + b]:

y + 2 = 3/2x + 6

y = 3/2x + 6 - 2

y = 3/2x + 4

The slope is therefore 3/2.

Negative reciprocal of 3/2 is -2/3.

Examine each of the equations given and see which equation has a slope of -2/3.

A. y = -3/2x +4, the slope is -3/2.

B.  y = -2/3x + 4, the slope is -2/3. (perpendicular)

C.  y = 2/3x +4, the slope is 2/3.

D. y = 3/2x +4, the slope is 3/2.

E. y+1=-4/6(x+5), rewrite in slope-intercept form

y+1=-4/6x + 20/6

y + 1 = -2/3x + 10/3

The slope is -2/3. (perpendicular)

F. y+ 1 = 3/2(x + 5), the slope is 3/2.

Therefore, the equations representing the lines that are perpendicular to line m are:

B. y = -2/3x +4

E. y+1=-4/6(x+5)

Answer:

[tex]\displaystyle (f\circ g)(-1) = 5[/tex]

Step-by-step explanation:

We are given the two functions:
[tex]\displaystyle f(x) = 2x + 3\text{ and } g(x) = -3x - 2[/tex]

And we want to find:
[tex]\displaystyle (f\circ g)(-1)[/tex]

Recall that this is equivalent to:
[tex]\displaystyle (f\circ g)(-1) = f(g(-1))[/tex]

Hence, find g(-1):
[tex]\displaystyle \begin{aligned} g(x) & = -3x - 2\\ \\ g(-1) & = -3(-1) - 2\\ \\ & = (3) - 2 \\ \\ & = 1 \end{aligned}[/tex]

Substitute:
[tex]\displaystyle f(g(-1)) = f(1)[/tex]

Find f(1):

[tex]\displaystyle \begin{aligned} f(x) & = 2x+ 3 \\ \\ f(1) & = 2(1) + 3 \\ \\ & = 5\end{aligned}[/tex]

In conclusion:
[tex]\displaystyle (f\circ g)(-1) = 5[/tex]

Answer:

3 and 27

Step-by-step explanation:

Step 1:  Determine which two terms we can use

We have the following numbers to choose from:  3, 14, 27

Adding two numbers to get a multiple of ten means that the number that we come up with needs to be divisible by ten.  For example:  20, 30, 50, 100 are all multiples of ten.

In this example the only one that would add up to create a multiple of ten is 27 and 3 which would give us 30 which is a multiple of 10.
