Answer:
equation: y=-2,000x+30,000
altitude after five minutes: 20,000
Step-by-step explanation:
y = altitude of the plane
x= slope (the plane descends -2000 feet per min, so the slope is -2000)
the y-intercept is 30,000 as the plane begins at 30000 feet above ground
7. The Majestic company increased the cost of an Astros jersey from $80 to $110. By what percentage was the price of
the Astros jersey increased?
Answer:
50%
Step-by-step explanation:
The cost = $80
Increased cost = $120
% Increase = (120-80) / 80 * 100
% Increase = 40/80 * 100
% Increase = 0.5 * 100
% Increase = 50%
So, the price of the Astros jersey increased by 50%

Answer:
The answer is the first option that states that you can write this expression as [tex]7(\frac{x}{8}) + \frac{3}{4} = -6[/tex]
Step-by-step explanation:
In order to solve this question we will need to know how to factor fractions. In our case we can do the following.
[tex]\frac{7}{8}x = \frac{7x}{8} = 7(\frac{x}{8})[/tex]
So now we since [tex]\frac{7}{8} x= 7(\frac{x}{8} )[/tex] ⇒
⇒ [tex]\frac{7}{8}x + \frac{3}{4} = -6[/tex]
[tex]7(\frac{x}{8}) + \frac{3}{4} = -6[/tex]

Using the graph. which of the following ordered pairs represents solutions to this inequalities? Select all that apply
(0,10)
(5,12)
(8,6)
(10,4)
(12,5)
(15,2)
Answer:
(8,6) and (10,4)
Step-by-step explanation:
solutions to the system of inequalities are in the purple shaded area, coordinates not landing in the purple shaded area are incorrect. The purple shaded area represents solutions for both lines red and blue.
Incorrect answers:
(0,10) because it lands in the blue shaded area ( meaning its the solution for only line blue and not line red)
(5,12) because it lands in the red shaded area ( meaning its the solution for only line red and not line blue)
(12,5) in red only
(15,2) in red only
Calculate the average time it took the car to travel 0.25 and 0.50 meters with two washers attached to the pulley. Record the averages, to two decimal places, in Table C of your Student Guide.
What is the average time it took the car to travel 0.25 meters?
seconds
What is the average time it took the car to travel 0.50 meters?
seconds
Answer:
1.92 second at 0.25 meters.
2.61 second at 0.50 meters.
Step-by-step explanation:
the average 2 washers on time travel of:
0.25 m : 1.94 / 1.95 / 1.87 = 1.92 second
0.50 m: 2.69 / 2.72 / 2.42 = 2.61 second
In this exercise we have to calculate the time that a car makes in a certain distance, in this way we find that:
A) In 0.25 meters in 1.92 second.
B) In 0.50 meters in 2.61 seconds.
We know that some information is given in the statement as:
In 0.25 meters the car speeds are: 1.94/ 1.95/ 1.87In 0.50 meters the car speeds are: 2.69 / 2.72 / 2.42Knowing that the formula for calculating time is given by:
[tex]Time= Distance/Speed[/tex]
So we have:
A) [tex](1.94 +1.95 + 1.87)/3= 5.76\\0.25/5.76=1.92 s[/tex]
B) [tex]2.69+ 2.72 + 2.42= 7,83\\0.50/7,83=2,61[/tex]

A two digit number is such that, the sum of its digit is 13.When the digits are interchange, the original number is increased by 9. Find the original number.
Answer:
Concept: Mathematical Representation
You have a two digit # __ The sum of the two digit # = 13The original # increased by 9 Hence we must find values that sum to 13. *Note they must be independently standing.8+5, 9+6, 7+6 , 6+7 , and etcThe value must also increase by 9 So logically it would be any result that when switched that value would be 76-67= 9.So the value must be 6730% increase on $50

A group of friends is sharing 212 pounds of berries. If each friend received 54 of a pound of berries, how many friends are sharing the berries? If 5 friends are sharing the berries, how many pounds of berries does each friend receive?
Answer:
Number of friend = 4 friends (Approx)
Amount of berries each friend get = 42.4 pound
Step-by-step explanation:
Given:
Total amount of berries = 212 pound
A. Number of friend
Number of friend = 212 / 54
Number of friend = 4 friends (Approx)
B. Amount of berries each friend get
Amount of berries each friend get = 212 / 5
Amount of berries each friend get = 42.4 pound
"Seventeen more than the product of a number and -3 is less than -29" translate this inequality
Answer: -3x + 17 < 29
product means multiply, so we multiply -3 and x as seen in the answer.
the less than sign is <. to remember it: less than starts with L and the sign < looks like an L
if 1 large bus and two small buses equal 100 people and 1 small bus and 2 large buses equal 158. how big is one large bus?
Answer:
One large bus can carry 72 people
Step-by-step explanation:
I kid you not I was messing around with my calculator and I found 72 for the large busses and 14 for the small ones. By doing 72+72+14 you get 158 and if you do 14+14+72 you get 100. Hope this helps.

For nitrogen to be a liquid, its temperature must be within 12.78 °F of –333.22 °F. Which equation can be used to find the maximum and minimum temperatures at which nitrogen is a liquid, x?
The equation that can be used to find the maximum and minimum temperatures is
Answer:
For nitrogen to be a liquid, its temperature must be within 12.78 °F of -333.22 °F. The equation |x + 333.22 | = 12.78 can be used to find x, which represents the maximum and minimum temperatures at which nitrogen is a liquid.

Answer:
Factored Form: f(x) = (x-7)(x-4)
Roots: x=7, x=4
Step-by-step explanation:
What we can do here is break the given expression into groups;
x^2-11x+28 ---> break the expression into groups
(x^2-4x) +(-7x+ 28) ---> factor out x from x^2-4x
x(x-4) + (-7x +28) ---> factor - 7 from -7x +28
x(x-4) -7(x-4) ---> combine
(x-7)(x-4)
so if f(x) = (x-7)(x-4) then the roots would be x=7 and x=4

Sharon makes bracelets and necklaces to sell at the school fair. She makes a total of 40 bracelets and necklaces. She makes 3 times as many bracelets as necklaces. Which system of equations can be used to determine how many bracelets, x, and how many necklaces, y, she m
Answer:
So, the system of equations are
x+y=40
x= 3 y
Step-by-step explanation:
Let's make system of equations for the given information.
Let x number of bracelets and y number of necklaces made.
So, for the information
She makes a total of 40 bracelets and necklaces, we can set up equation as
x+y=40
Now, for she makes 3 times as many bracelets as necklaces, we can set up equation as
x=3 y

Answer:
C.) y = 5/4x - 4
Step-by-step explanation:
Points: (0,-4) and (4,1)
m = y2 - y1/x2 - x1
m = 1 - (-4)/4 - 0
m = 1 + 4/4
m = 5/4
Point: (4,1) (you may choose any points, but I will choose these since they are the easiest to work with)
y - y1 = m(x - x1)
y - 1 = 5/4(x - 4)
y - 1 = 5/4x - 5
y = 5/4x - 5 + 1
y = 5/4x - 4
