4. Lin runs 4 laps around a track in 9 minutes at a constant speed.
A. How many minutes per lap is that? (1 point)
B. How many laps per minute is that? (1 point)
C. How long would it take Lin to run 15 laps at the same rate? (1 point)
Answer:
Number of minutes per lap = 2.25 minute
Number of lap per minute = 0.444 lap (Approx)
Time taken for 15 lap = 33.75 minutes
Step-by-step explanation:
Given:
Number of laps = 4
Time taken = 9 min
Computation:
Number of minutes per lap = 9 / 4
Number of minutes per lap = 2.25 minute
Number of lap per minute = 4 / 9
Number of lap per minute = 0.444 lap (Approx)
Time taken for 15 lap = 15 x 2.25
Time taken for 15 lap = 33.75 minutes

a new theater is being built for the city ballet. the balcony has 150 seats. the floor has 15 rows with x seats in each row. the number of people in the theater must be under 360 to meet fire safety regulations. what is the solution of thus inequality, and what is its meeting?
answers in the picture
The solution is Option A.
15x + 150 < 360 . The new theater must have fewer than 14 seats in each row on the floor to meet fire safety regulations
The inequality equation is x < 14
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Let the total number of people in the theater be = 360 people
The number of seats in the balcony = 150
Let the number of seats be x
The number of rows = 15
The number of seats in 15 rows = 15x
So , the inequality equation is
Number of seats in 15 rows + number of seats in the balcony < total number of people in the theater
Substituting the values in the equation , we get
15x + 150 < 360
On simplifying the equation , we get
Subtracting 150 on both sides of the equation , we get
15x < 210
Divide by 15 on both sides of the equation , we get
x < 14
Therefore , the value of x is less than 14
Hence , the new theater must have less than 14 seats in each row

Which of the following represents the value of x
f (x) = -3 + 7. Find the inverse of f(x) and its domain.
O A. f-1(x) 277 - 3, where x=-7
O B. f-1(x) = +7 +3, where x# 7
c. f-1(x) = 11 – 3, where x# 3
O D. f-1(x) = + 3, where x# 3
S
Note: Your function is missing some information. It seems your function is
[tex]f\left(x\right)=\frac{-3}{x}+7[/tex].
So, I am solving the question based on the function [tex]f\left(x\right)=\frac{-3}{x}+7[/tex], because it would still solve your query.
Answer:
Please see the explanation.
Step-by-step explanation:
Given the function
[tex]f\left(x\right)=\frac{-3}{x}+7[/tex]
A function g is the inverse of a function f for y = f(x), x=g(y)
[tex]y=\frac{-3}{x}+7[/tex]
Replace x with y
[tex]x=\frac{-3}{y}+7[/tex]
solve for y
[tex]y=-\frac{3}{x-7}[/tex]
so the inverse of [tex]f\left(x\right)=\frac{-3}{x}+7[/tex] will be:
[tex]f^{-1}\:\left(x\right)=-\frac{3}{x-7}[/tex]
Finding the domain of [tex]f^{-1}\:\left(x\right)=-\frac{3}{x-7}[/tex]
As we know that domain is the set of the possible input values where the function is defined.
so the function domain must be: [tex]x<7\quad \mathrm{or}\quad \:x>7[/tex]
Therefore,
[tex]\mathrm{Domain\:of\:}\:-\frac{3}{x-7}\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x<7\quad \mathrm{or}\quad \:x>7\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:7\right)\cup \left(7,\:\infty \:\right)\end{bmatrix}[/tex]

The price of a cup of coffee was $2.65 yesterday. Today, the price fell to
$2.50. Find the percentage decrease. Round your answer to the nearest tenth of a percent.
Answer:
5.6% decrease
Step-by-step explanation:
Answer:
5.7% decrease
Step-by-step explanation:
We must find the difference between prices. $2.65 - $2.50 = $0.15. Now we need to calculate what percent $0.15 is of $2.65. It is 5.7%! The price decreased, so it is a 5.7% decrease!

Write an equation for the line with slope -5 and point (2,4).
A. y = -5x + 18
B. y = -5x + 6
C. y = -5x + 14
D. Y = -5x - 14
Answer:
I'm not completly sure but im pretty sure its C.
Step-by-step explanation:
A. 1 Substitute y=−18y=−18 into y = x +12 y = x+ 12.− 18 = x +12 −18 = x+12
2 Solve for x x in −18 = x +12 − 18 = x + 12. x = −0 x = −30
3 Therefore, x = −30y = −18 x = −30 y = −18
B. The slope-intercept form is y = m x + b y = m x + b, where m m is the slope and

b Using the slope-intercept form, the slope is 0. m = 0
A. The slope-intercept form is y = m x + b y = m x + b, where m m is the slope and
b b is the y-intercept. y = m x + b y = m x +
b Using the slope-intercept form, the y intercept is 14. b = 14

What fractional part of a box remains after filling as many boxes as possible?
Answer:
13 7/11
Step-by-step explanation:
DIVIDE
The fractional part of a box remains after filling as many boxes as possible is 7/11
Given the following:
Amount of pounds of candy factory = 30 poundsIf the fudge is sold in 2 1/5 pound boxes., the number of boxes that can be filled is expressed as:Number of boxes filled = 30 ÷ 2 1/5
Number of boxes filled = 30 * 5/11
Number of boxes filled = 150/11
Number of boxes filled = 13 7/11
Hence the fractional part of a box remains after filling as many boxes as possible is 7/11
