Part A: which of the following is the most reasonable equation for the line of the best fit?
A. Y= 3/4x + 8
B. Y= x+8
C. Y= -3/4x +8
D. Y = 3/4x-8
Part B: using the equation from part A, what is the hourly wage for someone who worked ?
Answer:
number one is c y= -3/4x+8 and b is Formula for hourly rate from salary
To figure out your hourly wage based on your yearly salary, all you do is this: Take your yearly salary and divide that number by 52 (the number of weeks in a year) and then by 40 (the number of hours in a standard work week).

Write the first six terms of the sequence, beginning with n=1. a(n)=60n Enter the numbers, separated by commas.
Answer:
60, 120, 180, 240, 300, 360
Step-by-step explanation:
a(n)=60n
At n =1
a(1) = 60(1) = 60
At n = 2
a(2) = 60(2) = 120
At n = 3
a(3) = 60(3) = 180
At n = 4
a(4) = 60(4) = 240
At n = 5
a(5) = 60(5) = 300
At n = 6
a(6) = 60(6) = 360
60, 120, 180, 240, 300, 360

6x2 + 28x - 2 = 2x - 10
Answer:
x = -1/3 or x = -4
Step-by-step explanation:
Answer:
x= [tex]\frac{-1}{3}[/tex]
x= -4
Step-by-step explanation:
[tex]6x^2+28x-2=2x-10[/tex]
Subtract 2x - 10 from both sides.
[tex]6x^2+26x+8=0[/tex]
[tex]x= \frac{ -(26) +/ \sqrt{(26)^2-4(6)(8)} }{2(6)}[/tex]
x= [tex]\frac{-26 +/\sqrt{676-4(6)(8)} }{2(6)}[/tex]
x= [tex]\frac{-26 +/ \sqrt{676-192} }{2(6)}[/tex]
x= [tex]\frac{-26+/\sqrt{484} }{2(6)}[/tex]
x= [tex]\frac{-26+/22}{12}[/tex]
x= [tex]\frac{-26+22}{12}[/tex] = -0.33333333333333 = -1/3
x= [tex]\frac{-26-22}{12}[/tex]= -4
Jeremiah ate dinner at 6:17 pm . Before eating, it took him: - 25 minutes to cook dinner - 12 minutes to drive home from the grocery store - 36 minutes to the grocery shop. What time does Jeremiah arrive at the grocery store? Group of answer choices
Answer:
5:04 pm
Step-by-step explanation:
The computation of the time does Jeremiah arrive at the grocery store is shown below:
She ate dinner at 6:17 pm
She took 25 minutes for cooking
She took 12 minutes to drive home from grocery store
And, the 36 minutes to the grocery store
So, the time at which she arrive is
= 6.17pm - 25 minutes - 12 minutes - 36 minutes
= 6.17pm - 73 minutes
= 5:04 pm
What is the perimeter of the triangle?
The perimeter of the triangle is 34.2 units
How to determine the valueTo determine the value of the perimeter, we need to know the following;
A triangle has three sidesA triangle has three anglesThe sum total of the interior angles of a triangle is 180 degreesA triangle is a 3 - sided polygonThe formula that is used for calculating the perimeter of a triangle is expressed as;
P = a + b+ c
Such that a , b and c are the lengths of the sides of the triangle
Then, we have that;
Using the Pythagorean theorem
a² = 81 + 121
a² = 202
a = √202 = 14.2 units
Perimeter = 9 + 11 + 14.2
Add the values
Perimeter = 34.2 units

Which of these number sentences is NOT true?
Answer:
I’m pretty sure it’s D
Step-by-step explanation:
A. Lets convert millimeters into kilometers.
[tex]1cm = 10mm \\ 10mm = 1cm \\ 10 \times 30 = 1 \times 30 \\ 300mm = 30cm \\ 30cm > 3cm[/tex]
since 4000000mm = 4km, A is true. (Not the answer)
B. Lets convert millimeters into centimeters.
[tex]1cm = 10mm \\ 10mm = 1cm \\ 10 \times 30 = 1 \times 30 \\ 300mm = 30cm \\ 30cm > 3cm[/tex]
Since 300mm > 3cm, B is true. (Not the answer)
C. Lets convert millimeters to meters.
[tex]1000mm = 1m \\ 1m = 1000mm \\ 1 \times 5 = 1000 \times 5 \\ 5m = 5000mm[/tex]
Since 5m = 5000mm, C is NOT true. (Answer)
D.Lets convert metres to kilometres.
[tex]1km = 1000m \\ 1 \times 2 = 1000 \times 2 \\ 2km = 2000m \\ 2km < 20km[/tex]
Since 2000m < 20km, D is true. (Not the Answer.)

Your living room is a rectangular room, 35x 28 feet. There is a quarter circle hardwood floor (with a 6-foot radius) where the door is, but the rest of the room needs to be covered in carpet.
What is the area of the hardwood floor portion of the room?
Answer:
A = 28.274ft^2
Step-by-step explanation:
Since we have the radius, we can find the area of the circle if it was a full circle.
[tex]A = \pi r^{2}[/tex]
Plug in the radius of 6 feet:
[tex]A = \pi 6^{2}[/tex] = [tex]113.09734[/tex]
With the area of the full circle, we can divide the area by 4 to get the area of a quarter of that circle.
[tex]113.09734 / 4 = 28.274335[/tex] or about [tex]28.274ft^{2}[/tex]

Answer:
[tex]y = \frac{3}{5}x - 2[/tex]
Step-by-step explanation:
First, find two points that are located on the given line. In this case, we will use the following points:
(-5 , -5) , (0 , -2)
First, find the slope. The slope can be found using the slope formula:
slope (m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
Let:
[tex](x_1 , y_1) = (0 , -2)\\(x_2 , y_2) = (-5 , -5)[/tex]
Plug in the corresponding numbers to the corresponding angles:
m = [tex]\frac{-5 - (-2)}{-5 - 0}[/tex]
Simplify. Combine like terms, and then divide:
m = [tex]\frac{-5 + 2}{-5 - 0} = \frac{-3}{-5} = \frac{3}{5}[/tex]
Plug in [tex]\frac{3}{5}[/tex] into the slope (m), and a point into (x , y) to find the y-intercept:
[tex]y = \frac{3}{5}x + b\\-2 = \frac{3}{5}(0) + b\\-2 = 0 + b\\-2 = b\\b = -2\\[/tex]
Your answer:
[tex]y = \frac{3}{5}x - 2[/tex]

answer from me: 1,095.2 cm
Use 3.14 the diameter is 28.2, find the area of a circle.
answer from me: 624.26 m
identify the sets to which the number belongs.
answer from me: integer, rational number
thank you so much, plz help if you can
Answer:
1095.2 cm² is correct (don't forget to say it's cm squared)
624.26 m² is correct (ditto)
I'm not 100% sure what the identity of the sets means, you're probably correct though
Step-by-step explanation:
area = 74 x 14.8 = 1095.2 cm²
radius = 28.2/2 = 14.1
area = 3.14(14.1²) = 624.26 m²
how would you do log(3250) without a calculator
Answer:
Step-by-step explanation:
It depends on what level you are. Logs are most easily developed by using a series for the natural logarithms (instead of base 10, you use base e). Even that is a difficult process using a series that you won't be introduced to until your second calculus course..
For now, I'd be content to use a calculator. The series does not converge terribly quickly.

What is the value of x?
26°
to
O
X
= [ ? ]
Answer:
154°Step-by-step explanation:
The central angle and the angle between the tangents are supplementary, so
x + 26° = 180° ( subtract 26° from both sides )
26 - 26 = 0
180 - 26 = 154
x = 154°
Answer: 154
Step-by-step explanation: 26 + x = 180, subtract 26 from both sides, x = 154
