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
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

Solve 3n−2=4n−6 . Please help.
Step-by-step explanation:
Step 1: Subtract 4n from both sides.
3n−2−4n=4n−6−4n
−n−2=−6
Step 2: Add 2 to both sides.
−n−2+2=−6+2
−n=−4
Step 3: Divide both sides by -1.
−n−1=−4−1

Answer:
The answer is 27xStep-by-step explanation:
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
Round 11,900 to the nearest thousand.
5 stars for a correct answer.
Answer:
12,000
Step-by-step explanation:
The two thousands that 11,900 is in between are 11,000 and 12,000 which are our two options to choose from. 11,900 is only 100 away from 12,000 and 900 away from 11,000. Because the distance between 11,900 and 12,000 is shorter than the distance between 11,900 and 11,000, this means that 12,000 would be our answer since it is closer.

8x + 4 = 11 + 7x
x = 7
∴ ∠ = 11 + 7(7) = 60
30)
14x - 4 = 12x + 8
2x = 12
x = 6
∴ ∠ = 14(6) - 4 = 80

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
7. The speed of one car is 20% less than the speed of a second car. What per cent more time does the first car need to travel the same route as the second car?
Answer:
25% or more
Step-by-step explanation:
t1 = d1/v1 , t2 = d2/v2.
d1 = d2 , and v1 = 0.8 v2
t1 / t2 = d1/d2 x v2/v1 = v2/v1 ( as d1 = d2 )
t1/t2 = v2 / v1 = v2/0.8 v2 = 1/0.8 = 1.25

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)
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
