Dahlia noticed that her tomato plant grew new leaves at a steady rate, after the plant sprouted. She recorded the number of leaves on her plant on various days (see table) how many leaves should she expect on the 32nd day
Answer:
D; 85 leaves
Step-by-step explanation:
From what we can see, each 4 days there is a growth of an additional 9 leaves
So for the 20th day, we can see 58
The difference between the 20th and 32nd day is 12
The number of 4s we can see here is 12/4 = 3
For each 4, we can count extra 9 leaves
So for the 12, the number of leaves we can count is 3 * 9 = 27
we proceed to add this to 58
That will yield 58 + 27 = 85
It's c Bye bye have a amazing day

Answer:
2 sq rt 33
Step-by-step explanation:
1st step: subtract one, each side
(radical 2/3)r = 22
2nd step: set up a proportion
(radical 2/3)r = 22
3rd step: cross-multiply
radical 2*r = 66
4th step: solve for 'r'
r = 66 / radical 2
5th step: rationalize the denominator
multiply numerator and denominator by radical 2
6th step: simplify
(66[tex]\sqrt{2}[/tex]) / 2 = 33 [tex]\sqrt{2}[/tex]
A store spends 1/4 of its income on salaries and 1/6 of its income on advertising. If the store pays $150,000 for salaries, how much does it spend on advertising? Be sure to explain your reasoning.
Answer:
$100,000
Step-by-step explanation:
Let the total income of the store = [tex]\$x[/tex]
Total spends on salaries = [tex]\frac{1}{4}[/tex] of total income
Total spends on advertising = [tex]\frac{1}{6}[/tex] of total income
Also, we are given that:
Total money paid as salaries = $150,000
To find:
Total spends on advertising ?
Solution:
As per question statement, we can write the following equation:
[tex]\dfrac{1}{4}x =\$150000\\\Rightarrow x =\$150000\times 4\\\Rightarrow x = \$600000[/tex]
Now, as per the given statement, total spends on advertising are:
[tex]\dfrac{1}{6}x =\dfrac{1}{6}\times 600000 = \bold{\$100,000 }[/tex]
Therefore, the answer is $100,000

2x + y = 4
x + 3y = 5
6x - y = 11
2x + y = 10
- 6x - 3y = -2
HELP
Complete question is;
Arrange the systems of equations that have a single solution in Increasing order of the x-values in their solutions.
1) 2x + y = 10
x - 3y = -2
2) x + 2y = 5
2x + y = 4
3) x + 3y = 5
6x - y = 11
4) 2x + y = 10
-6x - 3y = -2
Answer:
Arranging the systems in increasing value of x gives;
System 2, system 3, system 1
Step-by-step explanation:
1) 2x + y = 10 - - - (eq 1)
x - 3y = -2 - - - (eq 2)
Multiply eq 1 by 3 to get;
6x + 3y = 30
Add it to eq 2 to get;
7x = 28
x = 28/7
x = 4
2) x + 2y = 5 - - - (eq 1)
2x + y = 4 - - - (eq 2)
Multiply eq 2 by 2 to get;
4x + 2y = 8
Subtract eq 1 from it to get;
3x = 3
x = 3/3
x = 1
3) x + 3y = 5 - - - (eq 1)
6x - y = 11 - - - (eq 2)
Multiply eq 2 by 3 to get;
18x - 3y = 33
Add to eq(1) to get;
19x = 38
x = 38/19
x = 2
4) 2x + y = 10 - - - (eq 1)
-6x - 3y = -2 - - - (eq 2)
Make y the subject in eq 1 to get;
y = 10 - 2x
Put in eq (2);
-6x - 3(10 - 2x) = -2
-6x - 30 + 6x = -2
0 = 0
Thus,no solution exists.
Arranging the systems in increasing value of x gives;
System 2, system 3, system 1

Answer:
food, video games, sports, naps, music
Step-by-step explanation:
I. Is point (6;-2) solution for -4x-5y=32? Why? Show me the steps how are checking?
II. What is the slope of the line through (-4,1) and (-7,-5)? Write the formula and show me the
solution.
III. What is the slope of the line x=-7? Why?
IV. What is the slope of the line y=-6? Why?
V. What will be x and y intercepts for the given equation y= -2x+25? How will you find them?
VI. Write the equation of the line through (-3,8) and (-4,-9) points.
Answer:
I. The point (6, -2) is not a solution for the given equation
II. The slope of the line going through (-4, 1) and (-7, -5) is 2
III. The slope of the line x = -7 is ∞
IV The slope of the line y = -6 is 0
V. The coordinate of the x-intercept is (12.5, 0)
The coordinate of the y-intercept is (0, 25)
VI. The equation of the line is y = 17·x + 59
Step-by-step explanation:
I. The given equation is -4·x - 5·y = 32
The given point = (6, -2)
Therefore;
The x-coordinate value of the point = 6
The y-coordinate value of the point = -2
Plugging in the x and y-coordinate values into the given equation gives;
-4 × (6) - 5 × (-2) = -14 which does not correspond to the given equation, therefore, the point (6, -2) is not a solution for the given equation;
We can also show, by making y the subject of the formula of the given equation, weather the point is a solution of the given equation as follows;
-4·x - 5·y = 32
y = (-4/5)·x - 32/5
For x = -2, we have;
y = (-4/5) × (-2) - 32/5 = - 4.8
Therefore, the point (6, -2) where y = 6 when x = -2 is not a solution of -4·x - 5·y = 32
II. The slope of a straight line, given two points on the line is given as follows;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Where the two points are (-4, 1), and (-7, -5), we have;
x₁ = -4, y₁ = 1, x₂ = -7, and y₂ = -5
[tex]Slope, \, m =\dfrac{-5-1}{-7-(-4)} =2[/tex]
The slope, m, of the line going through (-4, 1) and (-7, -5) is m = 2
III. The slope of the line x = -7 = ∞ because, the difference in the x-value which is the denominator of the slope equation = 0 for all differences in the y-coordinate values
IV The slope of the line y = -6 is 0 because, the difference in the y-values which is the numerator of the slope equation = 0 for all differences in the x-coordinate values
V. The x and y-intercept of an equation is found by finding the values of the variable, x or y, in the equation, when the other variable, y or x is equal to zero respectively, which is given as follows;
The given equation is y = -2·x + 25
When y = 0, we have the x-intercept as 0 = -2·x + 25
∴ 2·x = 25
x = 25/2 = 12.5
Therefore, the coordinate of the x-intercept is (12.5, 0)
When x = 0, we have the x-intercept as y = -2·x + 25 = -2 × 0 + 25 = 25
The coordinate of the y-intercept is (0, 25)
VI. The general equation of a straight line is y = m·x + c
Where;
m = The slope of the line
c = The y-intercept
For the line that goes through the points (-3, 8) and (-4, -9), we have;
[tex]The \ slope, \, m =\dfrac{-9-8}{-4- (-3)} = \dfrac{-9-8}{-4+3} = 17[/tex]
The equation in point and slope form is y - 8 = 17 × (x - (-3))
∴ y = 17·x + 51 + 8 = 17·x + 59
The equation of the line is y = 17·x + 59
Problem 11-15 Using CAPM A stock has an expected return of 10.5 percent, a beta of 1.55, and the expected return on the market is 8.5 percent. What must the risk-free rate be? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.G., 32.16.)
Answer:
the risk free rate of return is 4.86%
Step-by-step explanation:
The computation of the risk free rate is shown below;
As we know that
Expected return = Risk free rate of return + Beta × (Market rate of return - risk free rate of return)
10.5% = Risk free rate of return + 1.55 × (8.5% - Risk free rate of return)
10.5% = Risk free rate of return + 13.175% - 1.55 Risk free rate of return
10.5% - 13.175% = -0.55 risk free rate of return
-2.675% = -0.55 risk free rate of return
So, the risk free rate of return is
= 2.675% ÷ 0.55
= 4.86%
Hence, the risk free rate of return is 4.86%

Enter in the missing numbers to create equivalent ratios.
Answer:
The table with the missing number
1 5
2 10
5 25
10 50
Step-by-step explanation:
The form of the equivalent ratios is [tex]\frac{a}{b}[/tex] = [tex]\frac{c}{d}[/tex] , where a, b, c, and d are integers
From the given table, we will use the first row in all cases (a = 1 and c = 5)
∵ a = 1 and b = 2
∵ c = 5
→ By using the form of the equivalent ratios above
∴ [tex]\frac{1}{2}[/tex] = [tex]\frac{5}{d}[/tex]
→ By using the cross multiplication
∵ 1 × d = 2 × 5
∴ d = 10
∴ The first missing is 10
∵ a = 1
∵ c = 5 and d = 25
→ By using the form of the equivalent ratios above
∴ [tex]\frac{1}{b}[/tex] = [tex]\frac{5}{25}[/tex]
→ By using the cross multiplication
∵ 5 × b = 1 × 25
∴ 5b = 25
→ Divide both sides by 5
∴ b = 5
∴ The second missing is 5
∵ a = 1 and b = 10
∵ c = 5
→ By using the form of the equivalent ratios above
∴ [tex]\frac{1}{10}[/tex] = [tex]\frac{5}{d}[/tex]
→ By using the cross multiplication
∵ 1 × d = 10 × 5
∴ d = 50
∴ The third missing is 50
∴ The equivalent ratios are [tex]\frac{1}{5}[/tex] = [tex]\frac{2}{10}[/tex] = [tex]\frac{5}{25}[/tex] = [tex]\frac{10}{50}[/tex]
The table with the missing numbers
