As the time increases, the distance from the floor decreases by 40 cm per second. You find 40 by taking (6,1140) and (9,1020). The slope formula is y2 - y1 over x2- x1. Plug in the variables and you get (1020-1140)/(9-6)= -120/3= -40.

Ms. Petersen runs the school cafeteria. In October, she had to order 15 cases of chocolate milk twice because the students at her school love it so much. Each case contains c cartons of chocolate milk.
Answers
Ms. Petersen ordered 30c cartons of chocolate milk in October.
brief detail
To solve the problem, we need to know the total number of cartons of chocolate milk that Ms. Petersen ordered in October.
If she ordered 15 cases of chocolate milk twice, she ordered a total of 30 cases of chocolate milk (15 x 2).
We are also told that each case contains c cartons of chocolate milk. So, the total number of cartons of chocolate milk that Ms. Petersen ordered is:
30 cases x c cartons per case = 30c cartons
explanation:
No of cartoon of chocolate milk
= c
No of cases ordered = 15*2
Each cartoon contains chocolate milk = 15*2*c
=30 c

Answer:
A = plane
B = whale
C = sunken ship
Step-by-step explanation:
The given vertical number line is modelling the positions of objects and animals in relation to sea level.
Sea level is the average height of the surface of the world's oceans, which we use as a reference point to measure the elevation and depth of land and water features on Earth.
From inspection of the given number line:
Position A is above sea level.Position B is just below sea level.Position C is the furthest below sea level.We have been told that a plane is flying at 8,500 feet above sea level. Therefore, as position A is the only position above sea level, A = plane.
We have been told that a sunken ship is resting at 3,000 feet below sea level, and that directly above the ship, a whale is swimming 1,960 feet below sea level. Therefore, the whale is above the ship. As position B is above position C, this means that B = whale and C = sunken ship.

The senior class at Snellville rented and filled 12 vans and 14 buses with 796 students. General High rented and filled 14 vans and 12 buses with 738 students. How many students would fill 2 buses and 3 vans?
Answers
Answer:
133 students would fill 2 buses and 3 vans
Step-by-step explanation:
Let x be the no. of students in each van
No. of students in 12 vans = 12x
No. of students in 14 vans = 14x
Let y be the no. of students in each bus
No. of students in 14 buses = 14y
No. of students in 12 buses = 12y
We are given that The senior class at Snellville rented and filled 12 vans and 14 buses with 796 students.
12x+14y=796 ---1
We are also given that General High rented and filled 14 vans and 12 buses with 738 students.
14x+12y=738 ---2
Plot 1 and 2 on graph
12x+14y=796 --- Green line
14x+12y=738 --- Purple line
Intersection point gives the solution
Intersection point=(x,y)=(15,44)
No. of students in 1 van = 15
No. of students in 3 vans = \(15 \times 3 = 45\)
No. of students in 1 bus = 44
No. of students in 2 buses =\(44 \times 2 = 88\)
So,Total no. of students in 3 vans and 2 buses = 45+88=133
Hence 133 students would fill 2 buses and 3 vans
Which expression is NOT equivalent to the other 3 expressions
A: 5z + z - 1
B: 5z - 1 - z
C: 7z - (1+z)
D: (5z - 1) + z
Answers
To determine which expression is NOT equivalent to the other three expressions, we can simplify each expression and compare them.
A: 5z + z - 1 = 6z - 1
B: 5z - 1 - z = 4z - 1
C: 7z - (1+z) = 6z - 1
D: (5z - 1) + z = 6z - 1
We can see that expressions A, C, and D are equivalent since they all simplify to 6z - 1. Expression B, however, simplifies to 4z - 1, which is not the same as the other three expressions.
Therefore, the expression that is NOT equivalent to the other three expressions is B: 5z - 1 - z.

Mr. Chin asked his class to solve for y in the equation 8(3y - 5) = 9(y - 5) -1. Explain how to solve for y. Then solve.
Answers
Answer:
\(\Huge \boxed{\boxed{\bf{y = -\frac{2}{5} }}}\)
Step-by-step explanation:
To solve for \(\tt{y}\) in the equation \(\tt{8(3y - 5) = 9(y - 5) - 1}\), we'll need to simplify and isolate the variable.
Let's start by distributing the 8 on the left side and the 9 on the right side of the equation:
\(\tt{8(3y - 5) = 9(y - 5) - 1}\)\(\tt{24y - 40 = 9y - 45 - 1}\)Next, we'll combine like terms on both sides of the equation:
\(\tt{24y - 40 = 9y - 46}\)To isolate the variable, we'll move all the terms involving y to one side of the equation. Let's subtract 9y from both sides:
\(\tt{24y - 9y - 40 = 9y - 9y - 46}\)Simplifying further, we have:
\(\tt{15y - 40 = -46}\)To isolate "y," let's add 40 to both sides:
\(\tt{15y - 40 + 40 = -46 + 40}\)Simplifying, we get:
\(\tt{15y = -6}\)Finally, we can solve for "y" by dividing both sides of the equation by 15:
\(\tt{\frac{15y}{15} = \frac{-6}{15}}\)Simplifying the equation, we have:
\(\tt{y = -\frac{2}{5} }\)So, the solution to the equation is y = -2/5.

What is the shape of the addition to the house? What is the perimeter in units? Please help me answer this!!!!!
Answers
Answer:
answer is linked below hoped that helped
Step-by-step explanation:
The shape of Sheila is a square having a perimeter of 36 units.
What are the dimensions of a square?The area of a square is a product of it's any two sides or a product of diagonals divided by two. If a side has a length then the diagonal is a√2.
The perimeter of a square is the sum of the lengths of all the sides.
Let, The points E, F, G and H be a quadrilateral.
We know the distance formula,
\(d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2\).
So, The distance between the points EF is,
= \(\sqrt{(9/2 + 3/2)^2 + (- 5/2 + 5/2)^2\).
= \(\sqrt{(12/2)^2\).
= \(\sqrt{(6)^2\).
= 6 units.
Similarly the distance between the perpendicular side of EF, EG is also 6 units so this is a square having equal sides.
The perimeter of the house is 4×6 = 36 units.

Answers
Answer:

Step-by-step explanation:
Real numbers are a set of numbers that can be plotted on a number line, and include both rational and irrational numbers.
Division and multiplication numbers are not a type of number category.
And, non-real numbers are numbers that are not real, so they cannot be plotted on a number line.
So, Real numbers is the correct answer.
All the Real numbers, which include rational and irrational numbers, can be plotted on a number line.
What are rational numbers and irrational numbers?Rational numbers are numbers that can be written in the form of a/b where a and b are integers. Example: 1/2, 3.5 (which is writable as 7/5), etc. Irrational numbers are those real numbers that are not rational numbers. Know that all natural numbers are integers, and all integers are rational numbers. That means natural numbers are not irrational.

Sarah wanted to buy a TV. She had $390 in her pocket. The TV she wanted was $415; however she had a 10% off coupon. The sales tax is 6%. Does she have enough money to purchase the TV?
Answers
Answer: Sarah does not have enough money to purchase the TV.
Explanation: The total price is $395.91.
Answer:
No
Step-by-step explanation:
10% of 415
= 1/10 of 415
= 1/10 * 415
= $41.5
415 - 41.5 = $ 373.5
6% of 415
= 6% * 415
= $24.9
∴ $373.5 + $24.9 = $398.4
∴ Sarah cannot buy the TV as she is $ 8.4 short.
