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)
Answers
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 softball pitcher throws a softball to a catcher behind home plate. The softball is 3 feet above the ground when it leaves the pitcher’s hand at a velocity of 50 feet per second. If the softball’s acceleration is –16 ft/s2, which quadratic equation models the situation correctly?
h(t) = at2 + vt + h0
a) h(t) = 50t2 – 16t + 3
b) h(t) = –16t2 + 50t + 3
c) 3 = –16t2 + 50t + h0
d) 3 = 50t2 – 16t + h0
Answers
9514 1404 393
Answer:
b) h(t) = –16t^2 + 50t + 3
Step-by-step explanation:
If you put the given values in the given equation, you get ...
h(t) = at^2 + vt + h0
where a = -16, v = 50, h0 = 3
h(t) = -16t^2 +50t +3 . . . . . matches choice B
_____
Comment on the question
The given equation models the vertical height based on a vertical velocity of 'v'. It does not apply in the case where the horizontal velocity is v = 50 ft/s. None of the answer choices correctly models the situation where the pitcher is throwing toward the catcher.

Solve the equation. -18-6k = 6(1+ 3k) a) k= -2.67 b) k= -1 c) k = 1 d) k = 6
Answers
Answer: c) k = 1
Step-by-step explanation:
18 - 6k = 6 + 18k
18 = 6 + 12k
12 = 12k
1 = k
The value of k is -1.
Option B is the correct answer.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 7 is an equation.
We have,
-18 - 6k = 6 (1 + 3k)
Solve for k.
-18 - 6k = 6 (1 + 3k)
-18 - 6k = 6 + 18k
-18 - 6 = 18k + 6k
-24 = 24k
k = -24/24
k = -1
Thus,
k is -1.

Answers
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]

Answer:
We conclude that the slope of the line that is perpendicular to [tex]y=3x+6[/tex] will be: -1/3
Step-by-step explanation:
Given the equation
[tex]y=3x+6[/tex]
Comparing with the slope-intercept form
[tex]y=mx+b[/tex]
Here, m is the slope and b is the y-intercept.
so
[tex]y=3x+6[/tex]
Here the slope of line = m = 3
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
the slope of the perpendicular line will be: -1/3
Therefore, we conclude that the slope of the line that is perpendicular to [tex]y=3x+6[/tex] will be: -1/3

What fractional part of a box remains after filling as many boxes as possible?
Answers
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
