It cost $2.50 to rent bowling.each game costs $3.25.you have $22. How many games can you bowl
Answer:
6 games
Step-by-step explanation:
Use the equation 2.5+3.25x=22 to solve in which $2.50 is the initial amount to rent for Bowling, $3.25 the amount of game that is played, $22 for what you have, and x in which is the amount of games you can play at the max. Subtract 2.5 on both sides to get to 3.25x = 19.5. Divide 3.25 on both sides to get your final answer as 6 for your x value in which you can play up to 6 games.
Answer:
6 games
Step-by-step explanation:
you do 2.50 - 22 this you divide 3.25 by what you have left

Answer:
The height of the pyramid is 11.8 cm to the nearest tenth of a cm
Step-by-step explanation:
The formula of the volume of a pyramid is V = [tex]\frac{1}{3}[/tex] × A × h, where
A is the area of its baseh is its height∵ A right rectangular pyramid has base dimensions of 23.2 cm, 17.0 cm
∵ The area of the rectangle = Length × width
→ Assume that the length is 23.2 and the width is 17.0
∴ A = 23.2 × 17.0
∴ A = 394.4 cm²
∵ Its volume is 1552.4 cm³
∴ V = 1552.4 cm³
→ Substitute A and V in the rule above
∵ 1552.4 = [tex]\frac{1}{3}[/tex] × 394.4 × h
∴ 1552.4 = [tex]\frac{1972}{15}[/tex] h
→ Divide both sides by [tex]\frac{1972}{15}[/tex]
∴ 11.80831643 = h
→ Round it to the nearest tenth of a cm
∴ h = 11.8 cm
∴ The height of the pyramid is 11.8 cm to the nearest tenth of a cm

A new auditorium is begging built for a college the balcony has 200 seats the floor has 25 rows with x seats in each row the number of people in the auditorium must be under 750 to meet safety regulations what is the solution of this inequality and what is it's meaning
Question:
A new auditorium is being built for a college. The balcony has 200 seats. The floor has 25 rows with x seats in each row. The number of people in the auditorium must be under 750 to meet safety regulations. What is the solution of this inequality, and what is its meaning?
Answer:
[tex]200 + 25x < 750[/tex]
Number of seats in a row must be less than 22
Step-by-step explanation:
Given
Total = Less than 750
Current Seats = 200
Rows = 25
Seat per row = x
Required
Represent as an inequality
The scenario will be represented as:
[tex]Current\ Seats + Rows * x = Total[/tex]
Substitute 200 for Current Seats
[tex]200 + Rows * x = Total[/tex]
Substitute 25 for Rows
[tex]200 + 25* x = Total[/tex]
[tex]200 + 25x = Total[/tex]
Substitute <750 for Total.
The equation then becomes
[tex]200 + 25x < 750[/tex]
Solving further:
[tex]25x < 750 - 200[/tex]
[tex]25x < 550[/tex]
[tex]x < \frac{550}{25}[/tex]
[tex]x < 22[/tex]
This means that:
Number of seats in a row must be less than 22

In 2005, 120 students at Lincoln High School
had smart phones. By 2010, 345 students in the
same school had smart phones. Which of the
following best describes the annual rate of change
in the number of smart phones students had from
2005 to 2010 at Lincoln High School?
A) The average increase in the number of smart
phones per year is 40.
B) The average increase in the number of smart
phones per year is 45.
C) The average increase in the number of smart
phones per year is 50.
D) The average increase in the number of smart
phones per year is 55.
Answer:
The average increase in the number of smart
phones per year is 45
Step-by-step explanation:
Given that :
Number of students who had phones in 2005 = 120
Number of students who had phones in 2010 = 345
(345 - 120) / 5
225 / 5
= 45
Hence, average increase in number of smartphones per year = 45

Jay has lost his mother’s favorite necklace, so he will rent a metal detector to try to find it. A rental company charges a one time rental fee of $15 plus $2 per hour to rent a metal detector. Jay has only $35 to spend. What is the maximum amount of time he can rent the metal detector?
Answer:
he can rent it for 10 hours
Step-by-step explanation:
35 - 15 = 20
20 divided by 2 equals 10
Answer:
10 hours
Step-by-step explanation:
Say x is the number of hours he can rent the detector at most. Using it, we can set up this equation:
15 + 2x = 35
Subtract 15 from both sides
2x = 20
Divide by 2 on both sides
x = 10
Find the inverse of the function.
Answer:
The option 'b' is true.
Step-by-step explanation:
Given the expression
[tex]f\left(x\right)=\frac{2}{x+7}[/tex]
A function g is the inverse of the function f if for y=f(x), x=g(y)
[tex]y=\frac{2}{x+7}[/tex]
Replace x with y
[tex]\:x=\frac{2}{y+7}[/tex]
solve for y
[tex]y=\:\:\frac{2}{x}-7[/tex]
Thus,
[tex]f^{-} (x)=\frac{-7x+2}{x}[/tex]
Therefore, option b is true.

At Thompson Pass, 12 inches of snow fell during a 16 hour period. At this rate how much snow would fall in 24 hours? Pls help!
Answer:
18 inches of snow
Step-by-step explanation:
First, you'll have to find how much snow falls in a hour: 12/16 = .75 inches
Secondly, you'll multiply that by 24 to find the inches in a full day: 24 x .75 = 18
Answer:
18 inches of snow
Step-by-step explanation:
12:16
24 if you know the butterfly method which is 12/16=24 multiply 12 and 24 together and get 288 and then divide it by 16 which you get 18 inches of snow

an angle measures 115.4° less than the measure of its supplementary angle what is the measure of each angle
Answer:
32.3° and
147.7°
Step-by-step explanation:
Supplementary angles are angles with the sum of 180°
if one of the angle is 115.4° less than other then
(180 - 115.4) ÷ 2 = 32.3° is the measure of smaller angle and
32.3 + 115.4 = 147.7° is the measure of larger angle

The angles of AABC have the extended ratio of 7:8:15, respectively. Calculate the value for each of the angles A, B,
and C. Remember the angles in a triangle sum to 180 degrees!
Answer:
Step-by-step explanation:
Remark
A B C have to be multiplied by the same something. No matter what they are multiplied by the sum will be 180 degrees.
Equation
Let the angle ratios be multiplied by x
7x + 8x + 15x = 180
30x = 180
x = 180/30
x = 6
Answer
7*6 = 42
8*6 = 48
15*6 = 90
Total 180 as it should

Estimate the solution of the equation a(x) = b(x)
IMAGE BELOW
Answer:
The solution of the equation a(x) = b(x) is (9, 5.5)
Step-by-step explanation:
The solution of the system of the linear equations is the common ordered pair in their solutions, this solution is the point of intersection of the lines which represent the two equations graphically
In the given figure
∵ There are two lines, the blue line, and the red line
→ Let the blue line represents a(x) and the red line represents b(x)
∵ The solution of the equation a(x) = b(x) is the point of intersection of
the two lines
∵ The x-coordinate of this point is 9
∵ The y-coordinate of this point is between 5 and 6 (5.5)
∴ The coordinates of the point of intersection are (9, 5.5)
∴ The solution of the equation a(x) = b(x) is (9, 5.5)

Step-by-step explanation:
Given the function
[tex]y=3x+2[/tex]
the y-intercept of the function can be determined by setting x=0 and solving for y.
so
[tex]y=3x+2[/tex]
[tex]y=3(0)+2[/tex]
[tex]y=0+2[/tex]
[tex]y=2[/tex]
Thus, the y-intercept of the function represented in the graph will be: (0, 2)
