A company's stock began the day at $25.28 per share. That price drops by $1.16 each hour. A. What is the price per share after 5 hours? B. What will it be after 23 hours if this rate continues? C. Explain what the signs of the answers mean in this context.
Answer: A.) $19.48
B.) -$1.40
C.) The sign in B, the negative, means that if the price of the share were to continue dropping, then it will become negative.
Step-by-step explanation:
A. The price per share after 5 hours will be $19.48.
B. It will be $19.48 per share after 23 hours if this rate continues.
C. The sign indicates the company is at a loss.
What is the rate of change?It is defined as the change in values of a dependent variable with respect to the independent variables.
It is given that, A company's stock began the day at $25.28 per share. That price drops by $1.16 each hour.
1 hour = $1.16
5 hour =5 × $1.16
5 hours =$ 5.8 per share
The price drops per share after 5 hours are,
=$25.28-$ 5.8
=$19.48
B)
If the price drops by $1.16 each hour. The price after 23 hours will be,
1 hour = $1.16
23 hour =23 × $1.16
23 hours =$ 26.68 per share
=$25.28 -$ 26.68
=-$1.40 per share
Thus, the price per share after 5 hours will be $19.48, It will be $19.48 per share after 23 hours if this rate continues and the sign indicates the company is at a loss.

A grid shows the positions of a subway stop and your house. The subway stop is located at (7,3) and your house is located at (4-5). What is
the distance, to the nearest unit, between your house and the subway stop?
Answer:
9 units
Step-by-step explanation:
In a coordinate plane with point P( x , y) and Q(a,b ).
distance between these are points is given by equation
distance between PQ = [tex]\sqrt{(x-a)^2 + (y-b)^2}[/tex].
Coordinate of subway stop = (7,3)
Coordinate of house = (4-5)
Therefore using the above the formula to calculate distance between
house and the subway stop is given by
distance = [tex]\sqrt{(7-4)^2 + (3-(-5)^2}\\\\=>\sqrt{(3)^2 + (3+5)^2}\\\\=>\sqrt{9 + (8)^2}\\\\=>\sqrt{9 + 64}\\\\=>\sqrt{9 + 64}\\\\=>\sqrt{73}\\\\=>8.544[/tex]
Therefore, distance between house and the subway stop is 8.544 units.
But it is given that distance should be to the nearest unit.
any decimal value greater than or equal to .5 is equivalent to 1 in nearest unit.
Thus, 8.544 units is equivalent to 9 units (in nearest unit)
On Friday,2,364 cars parked in the garage at the mall. On Sunday 2,455 more cars parked In the garage than on Friday. How many cars parked in the garage during the two days?
Answer:
7183 cars
Step-by-step explanation:
On Friday, 2364 cars parked in the garage.
On Sunday, 2,455 more cars parked In the garage than on Friday.
This means that the number of cars parked on Sunday is 2455 plus the number of cars parked on Friday, that is:
2455 + 2364 = 4819 cars
Therefore, the number of cars parked in the garage in the two days is:
4819 + 2364 = 7183 cars
7183 cars were parked during the two days.

Quadrilateral DEFG has vertices at D(6,1), E(2,4), F(-5,4) and G(-1,1). What is the area of the quadrilateral?
Answer:
Area of the quadilateral = 35 square units.
Step-by-step explanation:
The coordinates of the quadilateral DEFG are given as
D(6,1), E(2,4), F(-5,4) and G(-1,1).
To obtain the area, we need the length of each of the quadilateral's sides.
The length of each side is the distance between the coordinates given.
The distance between two coordinates (x₁, y₁) and (x₂, y₂) is given as
d = √[(y₁ - y₂)² + (x₁ - x₂)²]
The lengths of the quadilateral's sides include DE, EF, FG and GD
DE = distance between D(6,1) and E(2,4)
DE = √[(1 - 4)² + (6 - 2)²]
DE = √(9 + 16) = 5 units
EF = distance between E(2,4) and F(-5,4)
EF = √[(4 - 4)² + (2 - -5)²]
EF = √(0 + 49) = 7 units
FG = distance between F(-5,4) and G(-1,1).
FG = √[(1 - 4)² + (-1 - -5)²]
FG = √(9 + 16) = 5 units
GD = distance between G(-1,1) and D(6,1)
DE = √[(1 - 1)² + (-1 - 6)²]
DE = √(0 + 49) = 7 units
The dimensions of the quadilateral show that it is a rectangle.
The area of a rectangle = (length) × (width)
Length = 7 units
Width = 5 units
Area of the quadilateral = 7 × 5 = 35 square units.
Hope this Helps!!!

Brennan measured a boarding school and made a scale drawing. A building at the school is 21 centimeters long in the drawing. The actual building is 147 meters long. What is the scale of the drawing?
Answer:
Check the explanation
Step-by-step explanation:
1 centimetre is = 0.01 meter
therefore the scale in Brennan drawing is 1 centimetre is used to represent 7 metres
Answer:
1 cm:7 meters
Step-by-step explanation:
The scale drawing shows the length in the drawing, then a colon and the actual lenght of the object. The actual building is 147 meters long and the drawing is 21 centimeters long. From this, we have:
21 cm:147 meters
As both numbers can be divided by 21, you can simplify and you would have that the scale of the drawing is:
1 cm:7 meters

these 15 colored pencils make up 20% of jordon's colored pencil collection.how many colored pencils does jordon have in his collections
Answer:
75 coloured pencils
Step-by-step explanation:
Let's say Jordon has x total pencils.
We know that 20% of these x pencils is 15, so we have:
20% * x = 15
Remember that % is just "out of 100", so 20% = 20/100 = 0.20. Then:
0.20x = 15
x = 15 / 0.20 = 75
Jordon has 75 coloured pencils.
Answer:
75 pencils
Step-by-step explanation:
Let the total no. of pencils be T
20% of T = 15
20/100 × T = 15
T = 15 × 100/20
T = 15 × 5
T = 75
Suppose the board of directors for Cosmic Coffee wants to know the price range for the lowest 40% of drink sales. Find the z-score associated with the upper boundary of of this price range.
Answer:
The z-score associated with the upper boundary of of this price range is -0.25.
Step-by-step explanation:
It is provided that the board of directors for Cosmic Coffee wants to know the price range for the lowest 40% of drink sales.
If X represents the price range of drink sales, then
P (X < x) = 0.40
Consider that X follows a Normal distribution.
To compute the probability of a normally distributed random variable we need to first convert the raw score to the z-scores.
The formula to z-score is:
[tex]z=\frac{X-\mu}{\sigma}[/tex]
Then,
P (X < x) = 0.40
⇒ P (Z < z) = 0.40
The value of z for this probability is:
z = -0.25
*Use a z-table.
Thus, the z-score associated with the upper boundary of of this price range is -0.25.
Answer:
-0.25

A rectangular playground is 10m longer than it is wide.The area of the playground is 1400m² Calculate the width and length of the playground. solve using quadratic formula please?
Answer:
[tex] 1400 = x(x+10)= x^2 +10x[/tex]
We can rewrite this expression like this:
[tex] x^2 +10 x -1400 =0[/tex]
And we can use the quadratic formula given by:
[tex] x = \frac{-b \pm \sqrt{b^2 -4ac}}{2a}[/tex]
Where [tex] a =1 , b=10 , c= -1400[/tex]
And replacing we got:
[tex] x = \frac{-10 \pm \sqrt{10^2 -4(10)(-1400)}}{2*1}[/tex]
And solving we got:
[tex] x_1 =32.75 , x_2 = -42.75[/tex]
And since the value can't be negative the answer would be x = 32.75 and the value of y = 32.75+10 =42.75
Step-by-step explanation:
For this case we know that we have a rectangular playground and the area can be founded with this formula:
[tex] A = xy[/tex]
Where x represent the width and y the length. From the problem we know that A =1400 m^2 and the heigth is 10m longer than the wide so we can write this condition as:
[tex] y = 10 +x [/tex]
And replacing this formula into the area we got:
[tex] 1400 = x(x+10)= x^2 +10x[/tex]
We can rewrite this expression like this:
[tex] x^2 +10 x -1400 =0[/tex]
And we can use the quadratic formula given by:
[tex] x = \frac{-b \pm \sqrt{b^2 -4ac}}{2a}[/tex]
Where [tex] a =1 , b=10 , c= -1400[/tex]
And replacing we got:
[tex] x = \frac{-10 \pm \sqrt{10^2 -4(10)(-1400)}}{2*1}[/tex]
And solving we got:
[tex] x_1 =32.75 , x_2 = -42.75[/tex]
And since the value can't be negative the answer would be x = 32.75 and the value of y = 32.75+10 =42.75
Answer:
Step-by-step explanation:
Given Data:
Area = 1400m²
L = 4+w
W= w
Area = L * W
1400 = ( 4+W) W ²
1400 = 4w + w ²
w ² + 4w - 1400 = 0
- b ± √ b ² - 4ac / 2a
Where;
a = 1
b = 4
c = -1400
- 4 ± √4² - 4(1)(-1400) / 2(1)
= - 4 ± 74.94 /2
= - 4 + 74.94 / 2 or - 4 - 74.94 / 2
= 35.47 or - 39.47
Help!?! I've been trying for the past half hour:/
Answer:
8 units.
Step-by-step explanation:
To find the y-intercept for the first equation: f(x)=2x²-4x+6, we can simply plug in '0' as 'x' to represent the y-intercept:
f(x)= 2(0)²-4(0)+6 ---> f(x)= 6
Therefore, the y-intercept of the first equation is (0,6).
-------------------------------------------------------------------------------
In the table, we can see that when x=0, y=-2. This is our y-intercept for the table.
When we find the difference between the two, we get:
6-(-2)= 8.

Ben decided to invest his savings into a friends local business if he invests 1,750 at an annual interest rate of 6.4% how much interest will he earn in 4 years
Answer:
He will earn an interest of $448 in 4 years
Step-by-step explanation:
In this question, we are interested in calculating the interest earned on an investment for a period of 4 years.
To calculate this interest, we shall be using the formula for simple interest but with slight difference in terms definition
Mathematically;
I = PRT/100
Where ;
P is the amount invested which is $1,750 according to the question
R is the interest rate which is 6.4%
T is the time which is equal to 4 years
Plugging these figures, we have
I = (1,750 * 6.4 * 4)/100 = 44,800/100 = $448

Kadesha says that the triangles represent a translation. On a coordinate plane, triangle A B C has points (1, negative 1), (1, negative 4), (4, negative 4). Triangle A prime B prime C prime has points (1, 5), (1, 1), and (4, 1). Which explains whether Kadesha is correct?
A) Kadesha is correct because triangle ABC is the pre-image and triangle A prime B prime C prime is the image.
B) Kadesha is correct because each point in triangle ABC moves five units up.
C) Kadesha is not correct because the number of units between points A and B is different than those between points A primeand B prime.
D) Kadesha is not correct because a translation is a horizontal movement.
Answer: Option C is most Appropriate.
C) Kadesha is not correct because the number of units between points A and B is different than those between points A primeand B prime.
Step-by-step explanation:
Coordinates of vertices of ΔABC are =A(1,-1), B(1,-4),C(4,-4)
Coordinates of vertices of ΔA'B'C' are =A'(1,5), B'(1,1),C(4,1)
Suppose, Preimage =ΔABC
Image =ΔA'B'C'
If you will find distance between two vertices of Both the triangles or length of sides of triangles
Kadesha is not correct because the number of units between points A and B is different than those between points A prime and B prime. Option (C) is the correct answer.
What is a graph?"A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner. The points on the graph often represent the relationship between two or more things".
For the given situation,
The triangle ABC has points A(1,-1), B(1,-4), C(4,-4)
The triangle A'B'C' has points A'(1,5), B'(1,1), C'(4,1)
Plot these two triangles in the graph as shown below.
The graph shows the relation between the triangle ABC and A'B'C'.
Both the triangles are separated by different units and are not images of one another.
Hence we can conclude that Kadesha is not correct because the number of units between points A and B is different than those between points A prime and B prime. Option (C) is the correct answer.

a. Two local supermarkets sell watermelons grown at McDowell's
farm. But Biggy Market sells their watermelons for $3.99 each,
regardless of size, whereas Harmless Trail Market sells their
watermelons for $0.19 per pound. For what weight will a
watermelon at Harmless Trail cost the same as any watermelon at
Biggy? If the largest watermelon grown at McDowell's farm
weighs 18 pounds, at which place should you buy your
watermelons?
Answer:
For the watermelon at Harmless to cost the same as any watermelon at Biggy, the watermelon needs to be 21 pounds.
You should buy your watermelon at Harmless.
Step-by-step explanation:
1. So in order to figure out the number of pounds, you need to divide 3.99 by 0.19 which should give u 21 pounds.
2. So in order to figure out where u should buy the watermelon from, u have to do 18 pounds times $0.19 which should give u $3.42 at Harmless while at Biggy it would cost $3.99

Ernesto wants to buy a snack from the vending machine. The vending machine has 5 different kinds of chips, 8 different candy bars, and 2 different kinds of cookies. If he chooses one at random, what is the probability that it is a cookie?
Answer:
The probability that it is a cookie is [tex]\frac{2}{15}[/tex]
Step-by-step explanation:
To find the probability that it is a cookie if he chooses one at random;
probability = required outcome / all possible outcome
The all possible outcome will be gotten by adding up all the snacks. that is;
required outcome = 5 + 8 + 2 = 15
The required outcome is the snack he chooses, that is; required outcome = 2
Probability (of choosing a cookie) =required outcome / all possible outcome
=[tex]\frac{2}{15}[/tex]
Therefore, the probability that it is a cookie is [tex]\frac{2}{15}[/tex]
