Rate of Change
The average velocity is defined as the rate of change of the distance with respect to time. The table shows the distances of an object as a function of time.
It's required to find the average velocity between 8 s and 20 s.
The rate of change can be approximated as the slope between two points. We take from the table the points (8,32) and (20,10) and calculate the slope.
The slope can be calculated with the equation:
[tex]\displaystyle v=\frac{d_2-d_1}{t_2-t_1}[/tex]
[tex]\displaystyle v=\frac{10-32}{20-8}=\frac{-22}{12}[/tex]
Simplifying:
[tex]\displaystyle v=-\frac{11}{6}[/tex]
Choice: B. [tex]\mathbf{-\frac{11}{6}\ \frac{inches}{second}}[/tex]

The length of a rectangle is
2
meters less than
3
times the width. The perimeter is
44
meters. Find the width.
Answer:
They did not state exactly what the width or length is. So in this case, let's name the number of width to be x. And thus we can derive to the conclusion of,
Step-by-step explanation:
Width : x
Length : x-44 (from the 1st sentence of question)
So, We all know that a rectangle has 2 Lengths and 2 widths. So we can derive the conclusion that,
2(x)+2(x-44)=150150
2x+2x-88=150150
4x-88= 150150
4x= 150150+88=150238
4x=150238
x= 150238÷4
=37559.5
Answer:
The width is 8 meters and the length is 3(8)-2=22 meters. Hope this helps (owo)/ brainlist please.
Step-by-step explanation:
Let x= the width
then 3x-2= length (because the length is 2 meters less than 3 times the width)
P=2l+2w
60=2(lenght)+2(width)
60=2(3x-2)+2x
60=6x-4+2x Distribute
60=8x-4 Combine like terms
64=8x Divide both sides by 8
8=x

A factory produces 161 cars in 7 hours at this rate how many cars will the factory produce in 1 week Assume the factory runs 24 hours a day 7 days a week
Answer:
3864 cars.
Step-by-step explanation:
First, to simplify the equation, we figure out how many hours are in a week.
24 x 7 = 168.
You can also figure out how many cars are made in a single hour.
161 / 7 = 23.
Now, we use the two in one final equation to get our final answer.
23 x 168 = 3864.
3864 cars are produced in 1 week.John spends $2.75 on donuts for his office employees every weekday. On Sunday mornings he takes his wife and kids to the donut shop and spends $12.99. How much money does John spend on donuts throughout the week?
How much money does John spend on donuts throughout the week?

(d)- $26.74
Step-by-step explanation:
John spends $2.75 on donuts for his office employees every weekday. On Sunday mornings he takes his wife and kids to the donut shop and spends $12.99. How much money does John spend on donuts throughout the week?
a) $23.24
b) $19.64
c) $29.14
d) $26.74
The total money spends on donuts throughout the week is $26.74 option (d) is correct.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
The missing options are:
a) $23.24b) $19.64c) $29.14d) $26.74We have:
John spends $2.75 on donuts for his office employees every weekday. On Sunday mornings he takes his wife and kids to the donut shop and spends $12.99.
Let the total number of working days in a week be 5
Total money spend on employees = 5×2.75 = $13.75
Total money spend on donuts throughout the week = 13.75 + 12.99
= $26.74
Thus, the total money spends on donuts throughout the week is $26.74 option (d) is correct.

if x=2y-5 and z=16y^3, what is z in terms of x
Answer:
z in terms of x is [tex]\mathbf{z=16\left(\frac{x+5}{2}\right)^3}[/tex]
Step-by-step explanation:
We are given:
[tex]x=2y-5\: and\: z=16y^3[/tex]
We need to find z in terms of x
First we can find value of y from x =2y-5
[tex]x =2y-5\\x+5 = 2y\\y=\frac{x+5}{2}[/tex]
Now, we can put value of y in [tex]z=16y^3[/tex] to find z in terms of x
[tex]z=16y^3\\Put\:y=\frac{x+5}{2}\\z=16(\frac {x+5}{2})^3[/tex]
So, z in terms of x is [tex]\mathbf{z=16\left(\frac{x+5}{2}\right)^3}[/tex]
A submarine was at the surface of the water. 21 seconds later, it was at a depth of 294 meters. What was the average change in the submarines depth each second?

Answer:
x=35, y=35
Step-by-step explanation:
To be honest, you don't even have to do any maths to figure this one out if you know the theory.
Basically, any angles standing on the same arc (like x and y) are equal. So we know x=y, and the first option(x=35,y=35) is the only option where x is the same as y.

C. is the right answer.A ladder is leaning against the side of a building and positioned such that the base of the ladder is 17 ft from the base of the building. If the
ladder reaches 23 ft above the ground, how long is the ladder. Round your answer to the nearest tenth
Answer:
The ladder is 28.6 feet long.
Step-by-step explanation:
Given that:
Length of base = 17 feet
Length above the ground = 23 feet
These forms two legs of right angled triangle.
The length of ladder will be the hypotenuse.
Using Pythagorean theorem;
[tex]a^2+b^2=c^2\\(17)^2 + (23)^2 = c^2 \\289 + 529 = c^2 \\c^2 = 818[/tex]
Taking square root on both sides
[tex]\sqrt{c^2}=\sqrt{818}\\c=28.6[/tex]
Hence,
The ladder is 28.6 feet long.
