Answer:
x+y≤15
6x+9y≥95
Step-by-step explanation:
Let x be the hours worked for babysitting and let y be the hours worked for house cleaning.
As Suzie babysits for $6 per hour. She also works as a house cleaner for $9 per hour.
Total hours she can work= 15 hours per week.
Hence,
x + y is less than or equals to 15
But since she wants to make at least $95 per week. It implies that,
6x + 9y is greater than or equal to 95
So from the statements above, the equations will be:
x+y≤15
6x+9y≥95
Select the correct answer.
What is the first step when solving the equation below for x?
A) Add 1.9 to both sides of the equation.
B) Divide each side of the equation by 4.
C) Add 0.2 to both sides of the equation.
D) Subtract 0.2 from both sides of the equation.

Daniel is currently 26 years older than his son. In six years he will be three times older
than his son. How old are both of them now?
Answer: sorr i onlyknow ti ar
Step-by-step:
Daniel is...remember "is" in a word problem means "equal"
So Daniel=x+26. x representing Daniel's son's age which we do not know.
In six years he will be three times his son's age, "times" meaning multiplication.
Daniel+6=3x, so just equate the two equations. So you must solve;
x+26=3x-6. From there I think you could handle things.
Given the arithmetic series: 2 + 4 + 6 +. Find the sum of T41 to T47
The series: 2 + 4 + 6 +.... is an arithmetic series
The sum of T41 to T47 is 616
How to determine the sum of the seriesThe series is given as:
2 + 4 + 6 +....
The above series is an arithmetic series with the following parameters:
Initial value, a = 2
Common difference, d = 2
Start by calculating S40 using the sum of n terms formula
[tex]S_n = \frac n2 * [2a + (n - 1)d][/tex]
So, we have:
[tex]S_{40} = \frac {40}2 * [2*2 + (40 - 1)*2][/tex]
[tex]S_{40} = 1640[/tex]
Calculate S47 using the same formula
[tex]S_{47} = \frac {47}2 * [2*2 + (47 - 1)*2][/tex]
[tex]S_{47} = 2256[/tex]
Subtract S40 from S47
[tex]S_{47} - S_{40} = 2256 - 1640[/tex]
[tex]S_{47} - S_{40} = 616[/tex]
Hence, the sum of T41 to T47 is 616

Write the equation in point-slope form of the line that passes through the points (4, 7) and (5, 1). Use the first point to write the equation.
Answer:
Step-by-step explanation:
Answer:
[tex]y-7=-6(x-1)[/tex]
Step-by-step explanation:
So first you need to find the slope of the line. You do this by doing [tex]m=\frac{y^{2}-y^{1}}{x^{1}-x^{2}}[/tex]. You would plug the points from the line into the equation to get [tex]m=\frac{1-7}{5-4}[/tex], and when you simplify you would get [tex]m=\frac{-6}{1}[/tex] or [tex]m=-6[/tex]. This means your slope is -6.
Now, point slope form is written as [tex]y-y^{1} = m(x-x^{1} )[/tex] so to write the equation you would plug in the slope and the first point to get [tex]y-7=-6(x-1)[/tex]

The probability that the average petal length will be between 1.3 and 1.6cm will be 0.5328.
How to calculate probability?From the complete question, x has an approximately normal distribution with a mean of 1.5cm and standard deviation of 0.2cm.
The associated probability for z values will be found in the normal distribution table and the probability will be subtracted. This will be:
= 0.6915 - 0.1587
= 0.5328

(CO 3) On the production line the company finds that 85.6% of products are made correctly. You are responsible for quality control and take batches of 30 products from the line and test them. What number of the 30 being incorrectly made would cause you to shut down production?
Answer and explanation:
There should be 85.6% correctly made products
If there is less than 85.6% correctly made products then production would be shut down
therefore 100-85.6= 14.4% of products can be incorrectly made and not more than that
In 30 batches 14.4% =0.144*30=4.32 products
Therefore there must not be more than 4.32 products incorrectly made in a batch of 30 else production is shut down

Carl’s dog, Alice, has a pet ramp she uses to go up the bed. A picture of Alice on her pet ramp is shown above. Enter the length of the ramp in feet. Round your answer to the nearest hundredth. *
Answer:
6.18 ft
Step-by-step explanation:
The ramp forms a right triangle.
We know two of the lengths of the right triangle, therefore, we would apply pythagorean theorem to find the longest length of the triangle, which is the length of the ramp.
The given lengths are 1.5 ft and 6 ft. The length of the ramp is the length of the longest side (hypotenuse length).
Thus, applying pythagorean theorem:
[tex] c^2 = a^2 + b^2 [/tex], where,
a = 1.5 ft
b = 6 ft
c = length of ramp
Substituting the values:
[tex] c^2 = 1.5^2 + 6^2 [/tex]
[tex] c^2 = 2.25 + 36 [/tex]
[tex] c^2 = 38.25 [/tex]
[tex] \sqrt{c^2} = \sqrt{38.25} [/tex]
[tex] c = \sqrt{38.25} [/tex]
[tex] c = 6.18 [/tex] (nearest hundredth)
length of the ramp = 6.18 ft

Write the linear equation in slope-intercept form passing through the point with the given slope. (0, 3); slope = -2
The required equation of the line in slope intercept form is given as 2x + y = 3
Given that,
To determine the linear equation in slope-intercept form passing through the point with the given slope. (0, 3); slope = -2.
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Equation of the line is given as,
y - y₁ = m (x - x₁)
Substitute the value in the equation,
y - 3 = -2 (x - 0)
y = -2x + 3
2x + y = 3
Thus, the required equation of the line in slope intercept form is given as 2x + y = 3

What are parallel lines?From the figure, we can see that
Angles formed by lines b and a are 89. 5 degrees
Angles formed by lines c and a are 91.5 degrees
Angles formed by lines d and a are 89.5 degrees
Angles formed by lines e and a are 88.5 degrees
Angles formed by lines f and a are 90.5 degrees
Since the angle formed by line b with a and d with a are equal that is 89.5
so these two lines will never intersect each other
