1) In the figure below, m_2 = 60°. Find the measure of each angle. Write which postulate(s) or
theorem(s) you used.
a ) angle 1
b) angle 2
c) angle 8
Answer:
Step-by-step explanation:
From the picture attached,
Two lines are the parallel lines and a third line (transversal line) is intersecting these parallel lines.
m∠2 = 60°
a). m∠1 + m∠2 = 180°
m∠1 + 60° = 180°
m∠1 = 180° - 60°
m∠1 = 120°
b). m∠2 = 60° [Given]
c). m∠2 = m∠8 = 60° [Alternate exterior angles are equal]

Step-by-step explanation:
Melissa has started training for a race. The first time she trains, she bikes 5 miles. Each subsequent time she trains, she bikes 0.5 mile farther than she did the previous time.
A. Use summation notation to write an arithmetic series to represent the total distance Melissa has biked after she has trained n times.
B. Use the formula for a partial sum of the series you wrote in part a, above, to answer this question: What is the least number of times Melissa must bike for her total distance biked during training to exceed 60 miles? (3 points)

Answer:
A. d = ∑[k=1,n] (4.5+0.5k)
B. 9
Step-by-step explanation:
A) The series has first term 5 and common difference 0.5. The general term is given by ...
an = a1 +d(n -1)
an = 5 + 0.5(n -1) . . . . substitute numbers for this series
an = 4.5 +0.5n . . . . . . simplify
The sum is the sum of these terms:
[tex]\displaystyle \boxed{d_n=\sum_{k=1}^n(4.5+0.5k)}[/tex]
__
B) The sum of terms of an arithmetic series is the average of the first and last, multiplied by the number of terms. We want to solve for n to make the sum greater than 60.
[tex]\displaystyle d_n=\frac{n}{2}(5 +4.5 +0.5n)\\\\\dfrac{n}{2}(9.5+0.5n)>60\\\\n(19+n)>240\qquad\text{multiply by 4}\\\\n^2+19n+9.5^2>240+9.5^2\qquad\text{complete the square}\\\\n+9.5>\sqrt{330.25}\qquad\text{square root}\\\\n>18.17-9.5=8.67\qquad\text{positive root, subtract 9.5}[/tex]
Melissa's total distance will first exceed 60 miles the 9th time she trains.

Let f(x) = 1/x and g(x) = x²-
6x. What
two numbers are not in the domain of fºg?
Separate your answers with a comma.
Enter the correct answer.
Step-by-step explanation:
f°g=[tex]f(g(x))[/tex]
[tex]g(x)=x^2-6x[/tex]
[tex]f(x)=1/x[/tex]
[tex]f(g(x))=[/tex][tex]\frac{1}{x^2-6x}[/tex]
if the denominator is zero the number is undefined which makes it not in the domain of the function
set [tex]x^2-6x[/tex] equal to 0
the values for x is 0 or 6
so the only value that is not in the domain of f°g is 0 and 6
Hope that helps :)

Sue wants to know whether wearing sunglasses improves driving performance. If she uses an independent groups design, she would manipulate the variable by randomly requiring half the drivers to drive with sunglasses and the other half to drive without sunglasses. having all drivers first drive without sunglasses and then with sunglasses. having half the drivers first drive without sunglasses and then with sunglasses and having the other half first drive with sunglasses and then without sunglasses. requiring all drivers to first drive with sunglasses and then without sunglasses.
Answer:
randomly requiring half the drivers to drive with sunglasses and the other half to drive without sunglasses.
Step-by-step explanation:
When employing an independent group design in a research or experimental study, the different groups in the study are assigned entirely different subjects such that, subjects in the treatment group are different from those in the control group. Therfore, adopting an independent group design in the scenario described above means diving the subjects into two at random with one half driving with sunglasses and the other half having to drive without it.

What is 562,148,900 in expanded form
Answer:
562,148,900 =
500,000,000
+ 60,000,000
+ 2,000,000
+ 100,000
+ 40,000
+ 8,000
+ 900
+ 0
+ 0
Answer:
Hello!
First we need to understand what expanded form is!
Expanded form is a way of writing a number to see the value of each digit. An example is:
111
100 + 10 + 1 = 111
So we must find the value of 562,148,900, in expanded form.
First we would find the first digit, and separate it from the other digits.
5
Then, we would count the digits behind that, and add it to the right of the five, in the form of zeroes.
500,000,000
We would continue this process for each digit, and then we would put them in addition form.
Your final answer would be,
500,000,000
60,000,000 +
2,000,000 +
100,000 +
40,000 +
8,000 +
900 +
0 +
0 +

Ryan works as a waiter at a local restaurant. For each dish he breaks, he has $2.15 deducted from his weekly pay. On a Monday night, Ryan broke 8 dishes, but he broke no more dishes the rest of that week. Which equation shows a way to calculate how much he had to pay for the broken dishes that week?
A. 8 * $2.15 = $17.20
B. 8+ (-$2.15) = $5.85
C. -8- (-$2.15) = -$5.85
D. 8 + $2.15 = $10.15
The answer would be A.
Step-by-step explanation:
8 x $2.15= $17.20

How many square feet of paint will be needed to cover the shed, not including the roof?
4 ft
6 it
41
6 ft
8017
Ob
44
6011?
Od
92
Answer:
80 ft^2 of paint would be needed
Step-by-step explanation:
Since we do not consider the roof, all we need do is to calculate the area of the shape without the roof side
So without the roof, we have 4 rectangles
we have 4 ft by 4 ft on both sides
Then 6 ft by 4 ft on the other two sides
mathematically, the area of a rectangle is the product of its sides
so, we have the total area as;
2(6 * 4) + 2(4 * 4)
= 2(24) + 2(16)
= 48 + 32
= 80 ft^2

Answer:
I'll setup the formula and you can do the calculations.
Step-by-step explanation:
you need to add up the areas of 2 rectangles (10x16), 1 rectangle on the bottom (12x16) and 2 triangles ( height = 8 and base = 12)
area of rectangle = wide x length
area of triangle = 1/2 base x height

En una tienda de ropa vas a comprarte una pantalones que están de 150 a 90 euros y una camiseta de 40 a 24 ¿ tienen el mismo porcentaje de rebaja ?
Respuesta:
Sí, tienen el mismo descuento del 40%
Explicación paso a paso:
Dado :
PANTALÓN :
Precio inicial = 150
Precio con descuento = 90
Porcentaje de descuento en el precio:
(150 - 90) / 150 * 100%
60/150 * 100%
0,4 * 100
= 40%
CAMISA:
Precio inicial = 40
Precio con descuento = 24
Porcentaje de descuento en el precio:
(40-24) / 150 * 100%
16/40 * 100%
0,4 * 100
= 40%
Sí, tienen el mismo descuento del 40%
Mario's grape vine grows 7.5 inches in 3 weeks. At this rate, how much will the grape vine grow in 15
weeks?
Answer:
It will grow 37.5 inches
Step-by-step explanation:
It grew 7.5 in 3 weeks. Divide 7.5 by 3 and you'll get 2.5. So that means every week it grows 2.5 inches. So multiply 2.5 x 15 and you'll get 37.5 inches

First, distribute 10 to all terms within the parenthesis:
10(6x + 8)
10 * 6x = 60x
10 * 8 = 80
60x + 80
Next, Add like terms. Like terms are terms with the same amount of the same variable:
8x + 60x + 80
(8x + 60x) + 80
68x + 80
68x + 80 is your answer.

Answer:
68x + 80
Step-by-step explanation:
To solve the following problem,
8x + 10 ( 6x + 8 )
First, distribute the (10), multiply every term int he parenthesis by the term outside of it,
8x + 10(6x + 8)
8x + (10)(6x) + (10)(8)
Simplify,
8x + 60x + 80
68x + 80

What is the radius of a cylinder that has a volume of 500 ft ³ and that is 10 ft tall?
Answer:
The answer is 3.98942, rounded its 3.99.
Step-by-step explanation:
Answer:
3.99 ft
Step-by-step explanation:
Volume of a cylinder = πr²h
π = 3.14
volume = 500 ft³
height = 10 ft
πr²h = 500
3.14×r²×10 = 500
r² = 500/3.14×10
= 15.92..
= √15.92
r = 3.9899.. ≈ 3.99 ft
