Answer:
3.75 hours
Step-by-step explanation:
Let us represent the number of hours = x
The price of Stock A at 9 A.M. Was $13.63. Since then, the price has been increasing at the rate of $0.06 each hour.
$13.63 + $0.06× x
= 13.63 + 0.06x
At noon the price of Stock B was $14.38. It begins to decrease at the rate of $0.14 each hour.
$14.38 - $0.14 × x
14.38 - 0.14x
If the two rates continue, in how many hours will the prices of the two stocks be the same?
Stock A = Stock B
13.63 + 0.06x = 14.38 - 0.14x
Collect like terms
0.06x + 0.14x = 14.38 - 13.63
0.20x = 0.75
x = 0.75/0.20
x = 3.75 hours
The prices of the two stocks will be the same after 3.75 hours
If f(x) = 5x/3 + 5, which of the following is the inverse of f(x)?

During flu season, there were 93 students out of school on a particular day. If this is 12% of the total number of students at the school, how many total students are enrolled at the school?
The total students that are enrolled at the school is = 868 students
Calculation of total studentsIn the flu season the number of students absent from school = 93
The percentage of students absent from school = 12%
If 93 students = 12%
X students = 100%
Make X the subject of formula,
X = 93× 100/12
X= 9300/12
X = 775
Therefore, 775 + 93 = 868
The total students that are enrolled at the school is = 868 students.

The table shows the number of condo sales per month for a new condo building. Select all the equations that could represent the number of sales.
Answer:
Option (1) and (5)
Step-by-step explanation:
Let the equation representing number of sold is,
y - y' = m(x - x')
Where m = number of condo sold per month
(x', y') is a point from the given table,
Slope of line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope of the passing through (1, 8) and (0, 11) will be,
m = [tex]\frac{11-8}{0-1}[/tex] = -3
Therefore, equation of the line passing through (3, 2) and slope (-3),
y - 2 = (-3)(x - 3)
y - 2 = -3(x - 3)
Similarly, equation of the line passing through (0, 1) and slope (-3),
y - 11 = -3(x - 0)
Therefore, Option (1) and (5) will be the answer.

Simplify the expression.
27^1/3
Answer:
9
Step-by-step explanation:
Rewrite 27 as 3 ³.
(3³)[tex]\frac{1}{3}[/tex]
Apply the power rule and multiply exponents, [tex](a^{m})^{n} =a^{mn}[/tex]
3³([tex]\frac{1}{3}[/tex])
The simplified value of exponential expression27(1/3) is about equivalent to 3.
Here, we have,
give that,
the expression is 27^1/3.
We know,
An exponential expression is a mathematical expression that requires raising a variable to a power.
now, we get,
Rewrite 27 as 3 ³.
so, we have, (3³)^1/3
Apply the power rule and multiply exponents, nᵃᵇ= (nᵃ)ᵇ
3³^(1/3) = 3
i.e. we have,
(27)^1/3
= (3^3)^1/3
= 3
As 3*3*3 is 27 so we can write 3^3 ...both power got cancelled hence we got 3 as a answer.
Hence, The simplified value of exponential expression27(1/3) is about equivalent to 3.

- 7y = - 21 ( divide both sides by - 7 )
y = 3
Answer:
[tex]y=3[/tex]
Step-by-step explanation:
[tex]-7y - 17 = -38[/tex]
Add 17 both sides
[tex]-7y - 17 + 17= -38+17[/tex]

Sound policy requires that a certain number of trees be planted for every tree that is cut down for example of 8 trees are cut down 48 trees will be planted a homeowner is going to cut down five trees on his property how many trees will be planted 1/5 are cut down
Answer:
30 trees
Step-by-step explanation:
Given the policy:
8 trees are cut down 48 trees will be planted
If homeowner is going to cut down five trees on his property how many trees will be planted
Since :
8 trees cut down = 48 planted
5 trees cut down = X
Cross multiply :
8 * X = 48 * 5
8X = 240
X = 240/8
X = 30
Hence, 30 trees will need to be planted

Amelia ,Hayden and Sophie did a test the total for the test was 75 marks Amelia got 56% of 75 marks Hayden got 8/15 0f the 75 marks Sophie got 43 out of 75 marks who got the highest
Step-by-step explanation:
Amelia got 56% of 75 so
(56/100)*75=(56*75)/100=4200/100=42
Hayden got 8/15 of 75 so
(8/15)*75=(8*75)/15=600/15=40
and Sophie that got 43 out of 75
so we see that Sophie got the highest points.
Given parameters:
Total test score = 75marks
Percentage of Amelia score = 56%
Fraction of Hayden's score = [tex]\frac{8}{15}[/tex]
Sophie's score = 43marks
Unknown:
The person with the highest score = ?
Solution:
Since total score = 75marks;
Amelia's score = [tex]\frac{56}{100} x 75[/tex] = 42marks
Hayden's score = [tex]\frac{8}{15} x 75[/tex] = 40marks
Sophie's score = 43 marks
The person with the highest score is Sophie with a mark of 43.

A seat on a Ferris wheel is level with the center of the wheel. The diameter of the wheel is 200 feet. Suppose the wheel rotates 60°, causing the height of the seat to decrease. How much closer to the ground is the seat after the is to be determined.
These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operation.
Diameter = 200
Radius = Diameter/2 = 100
Rotational angle = 60°
Let the height be h
tan60 = h/100
√3 = h/100
100√3 = h
Thus, the required height of the seat from the ground is 100√3. Option D is correct.

Answer:
y=640-3x
Step-by-step explanation:
The total amount of ounces in the bucket is 640, and it decreases by 3 each minute. For example, if you plug in 3 for x into that equation (which would represent 3 minutes), you would lose 9 ounces of water, which makes sense in the terms of the equation.
The point (0,50) identifies the unit rate as 50.

Step-by-step explanation:
x = (a + b + c)/ab
Isolate the variable by multiplying/dividing everything, but variable a to both sides
x × ab/(b+ c) = (a + b + c)/ab × ab/(b + c)
