A. 7
B.14
C.42
D.126
Answer:
B. 14
Step-by-step explanation:
The sum of infinite geometric series is given by
[tex]\frac{a}{1-r}[/tex]
0.126126126... = [tex]\frac{126}{1000}+\frac{126}{1000000}+\frac{126}{1000000000}[/tex]
Here a =126/1000, r= 1/1000
0.126126126... = [tex]\frac{126/1000}{1-1/1000}[/tex] =126/999 = 14/111

what is the measure of A, in degrees?
Answer:
B
Step-by-step explanation:
Since AB = AC = 8 then the triangle is isosceles and
∠C = ∠B = 30° ( base angles of an isosceles triangle )
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the base angles from 180, hence
∠A = 180° - (30 + 30)° = 180° - 60° = 120° → B

Long division is a method used to divide two polynomials in algebra. It involves arranging the dividend and divisor, determining the term of the quotient, subtracting and repeating until there are no more terms left to bring down.
Explanation:
In algebra, long division is a method used to divide two polynomials. It is especially useful when the dividend (the polynomial being divided) has a higher degree than the divisor (the polynomial dividing the dividend).
Here's a step-by-step explanation:
Arrange the dividend and divisor in descending order.Determine the term of the quotient by dividing the leading terms of the dividend and divisor.Multiply the entire divisor by the term of the quotient and subtract it from the dividend.Repeat steps 2 and 3 until there are no more terms left to bring down.The result is the quotient and any leftover terms are the remainder.Let me know if you need further assistance or if there's anything else I can help you with!

The area of a rectangular dog pen is 8/1/2 square feet. If the width is 3/2/5 feet what is the length in feet
Answer:
l = 2 1/2 ft
Step-by-step explanation:
The formula for A is l*w for a rectangular length
A= lw
Putting in what we know
8 1/2 = l * 3 2/5
I will change mixed numbers to improper fractions
8 1/2 = (2*8+1)/2 = 17/2
3 2/5 = (5*3+2)/5 = 17/5
17/2 = l*17/5
Multiply both sides by 5/17 to isolate l
5/17* 17/2 = l* 17/5 * 5/17
5/2 = l
Changing this back to a mixed number
2 1/2 = l

In addition to an $80 bonus Joan earned eight dollars per hour working last week Joans total earnings last week or $240 how many total hours did she work last week
Answer:
20 hours
hope it helps
Step-by-step explanation:
total earnings was $240 but to find how much he made working you first have to deduct the $80 bonus
240 - 80 = 160
so he made $160 working now to find out how many hours worked you have to divide by 8 because he got paid $8.00 an hour
160 ÷ 8 = 20
Answer:
20hrs
Step-by-step explanation:
We need to find out how many hours she worked last week.
The bonus added $80 to the money she got from her hours worked so lets take that away:
240-80=160
Since she gets $8/hr we should divide 160 by 8
160÷8=20
Rob spent 25\%25% more time on his research project than he had planned. He spent an extra hh hours on the project.
Which of the following expressions could represent the number of hours Rob actually spent on the project?
Answer: 5h represents the number of hours Rob actually spent on the project.
Step-by-step explanation:
Let Rob planned that he will spend x hours in his project.
According to the question,
He spent 25% more time on his project than he planned.
That is, his actual time = x + 25% of x = 125% of x
Again according to the question,
He spent an extra h hours on his project.
That is, 25% of x = h
[tex]\frac{25\times x}{100} = h[/tex]
[tex]x=\frac{100h}{25}[/tex]
x = 4h
Thus, his actual time = 125% of x = 125% of 4h = [tex]\frac{125\times 4h}{100}[/tex] = 5h
Which is the required expression.

A lot is in the shape of a trapezoid. The sum of the bases is 280 feet. If the area of the lot is 8,400 square feet, what is the distance across the lot, i.e., the altitude of the figure? The altitude of the trapezoid is feet.
Answer:
The altitude of the trapezoid is 60 feet.
Step-by-step explanation:
Trapezoid
Sum of the bases: B+b=280 feet
Area of the trapezoid: A=8,400 feet^2
Altitude of the trapezoid: h=?
The formula to calculate the area of a Trapezoid is:
A = (1/2) (B+b) h
Replacing the given values:
8,400 feet^2 = (1/2) (280 feet) h
(1/2) (280 feet) = (140 feet)
8,400 feet^2 = (140 feet) h
Solving for h: Dividing both sides of the equation by 140 feet:
8,400 feet^2 / (140 feet) = (140 feet) h / (140 feet)
60 feet = h
h = 60 feet
Answer: The altitude of the trapezoid is 60 feet.

You earn $8.60/hr. You work 32 hr/wk and your deductions are FICA (7.65%), federal tax withholding (10.6%), and state tax withholding (8.25%). How much do you have direct-deposited bi-weekly?
The amount that is direct-deposited bi-weekly is 404.30.
To calculate the bi-weekly direct deposit amount, we need to follow these steps:
1. Calculate the gross pay for a week:
Gross pay per week = Hourly wage * Hours worked per week
Gross pay per week = $8.60/hr * 32 hr/wk
Gross pay per week = $275.20
2. Calculate the total deductions per week:
Total deductions rate = FICA rate + federal tax rate + state tax rate
Total deductions rate = 7.65% + 10.6% + 8.25%
Total deductions rate = 26.5%
Total deductions per week = Gross pay per week * Total deductions rate
Total deductions per week = $275.20 * 26.5%
Total deductions per week = $73.049
3. Calculate the net pay for a week:
Net pay per week = Gross pay per week - Total deductions per week
Net pay per week = $275.20 - $73.049
Net pay per week = $202.151
4. Calculate the bi-weekly net pay:
Bi-weekly net pay = Net pay per week* 2
Bi-weekly net pay = $202.151 * 2
Bi-weekly net pay = $404.302
Since the net pay is calculated to the nearest cent, we can round the bi-weekly net pay to the nearest cent as well:
Bi-weekly net pay (rounded) = $404.30
Therefore, the amount that is direct-deposited bi-weekly is 404.30.
The answer is: $404.30.
Solve for v.
.
Simplify your answer as much as possible.
Answer:
v = 9
Step-by-step explanation:
Use the method of cross- multiplying
[tex]\frac{a}{b}[/tex] = [tex]\frac{c}{d}[/tex] ⇒ ad = bc
8v = 12 × 6
8v = 72 ( divide both sides by 8 )
v = 9
Answer:
[tex]v=9[/tex]
Step-by-step explanation:
The given equation is
[tex]\frac{v}{12}=\frac{6}{8}[/tex].
We multiply both sides of the equation by 12 to obtain,
[tex]12\times \frac{v}{12}=\frac{6}{8}\times 12[/tex].
This implies that;
[tex]v=\frac{3}{4} \times 12[/tex]
This gives
[tex]v=\frac{3}{1} \times 3[/tex]
[tex]v=3\times 3[/tex]
[tex]v=9[/tex]

Answer:
D
Step-by-step explanation:
note that the values in the domain map to the values in the domain as
- 1 → 2 ( that is 1 + 3 = 2 )
3 → 6 ( that is 3 + 3 = 6 )
5 → 8 ( that is 5 + 3 = 8 )
In each case 3 is added to the value in the domain(x) to obtain the value in the range ( y = f(x) )
Hence f(x) = x + 3 → D

Answer:
Step-by-step explanation: To find a y intercept you must find what y is when x is 0 so because it already tells you on the table the y intercept is 4. To find slope take 2 x intercepts and 2 y intercepts. For this well take the 0,4 and 5,1. The take the y from both pairs and minus them so it will look like 4 minus 1. Then draw a line under the equation under this line do the same thing but with the x's from both pairs so 0-5 then you will get as a result of both -3/5 as your slope.
Answer:
slope: -3/5
y-intercept: (0, 4)
slope-intercept form: y = -3/5x + 4
Step-by-step explanation:
Finding the slopeTo find the slope of this line, you would take two points from the table and substitute their coordinates into the slope formula.
Slope formula: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
I'm going to use the points (0, 4) and (5, 1). You can really use any point from the table. Substitute these points into the formula to find the slope.
(0, 4), (5, 1) → [tex]\frac{1-4}{5-0} \rightarrow \frac{-3}{5}[/tex]
This means the slope of the line is -3/5.
Finding the y-interceptThe y-intercept will always have the value of x be 0 (so the point is solely on the y-axis), so by looking at the table we can see that the y-intercept is at (0, 4).
Finding the slope-intercept formSince we have the slope and a point of the line, we must use point-slope form to find the equation of the line in slope-intercept form. Substitute in the point (0, 4) --you could use any point from the table-- and the slope -3/5 into the point-slope form equation.
point-slope form: y - y1 = m(x - x1) --you'll be substituting the point coordinates and slope into y1, x1, and m.
y - (4) = -3/5(x - (0))
Simplify.
y - 4 = -3/5x
Add 4 to both sides.
y = -3/5x + 4 is the equation of the line in slope-intercept form (you have both the slope and the y-intercept in this form).
