If <1 and <2 are
supplementary angles with
m <1 = 10x +5 and m <2= 6x-1, what are the measure-
ments of both angles?
Answers
Step-by-step explanation:
The sum of measure of supplementary angles = 180°
The measure of angle 1 is given as 10x + 5 and the measure of angle 2 is given as 6x - 1
10x + 5 + 6x - 1 = 180 add like terms
16x + 4 = 180 subtract 4 from both sides
16x = 176 divide both sides by 16
x = 11
To find the measure of each angle, relace x with 11
angle 1,
10*11 + 5 = 115
angle 2,
6*11 - 1 = 65

Marsha is filing her federal income tax return with the Single filing status. She had an adjusted gross income of $56,800 last year and is trying to decide whether to take the standard deduction of $5700 or to itemize deductions. Last year she had $4900 in medical expenses, $3100 in state and local income taxes paid, $1940 in mortgage interest paid, $530 in charitable contributions, and $1200 in non-reimbursed work expenses
Answers
Marsha must claim for itemized deductions.
Given,
Last year's gross income is $56,800.
Medical expenses = $4900
State and local income taxes paid = $3100
The mortgage interest paid = $1940
Charitable contributions = $530
Non-reimbursed work expenses = $1200
Standard deduction = $5700
The sum of all the expenses of last year = $4900 + $3100 + $1940 + $530 + $1200 = $11,670
And the Standard deduction is $5700.
Which is, $11,670 - $5700 = $5970 lesser.
Therefore, Marsha must claim for itemize deductions rather than the standard deductions.

From the translation described, If vertex A is at (-1, 2) and vertex B is at (1, 5), then vertex A' is at (-4, 8). See the justification for the same below.
What is a vertex?A vertex is a specific point of a mathematical object that is often where two or more lines or edges intersect. Angles, polygons, polyhedra, and graphs are the most typical places to find vertices. Nodes are another name for graph vertices.

Last month, Sally and Roger sold candy to raise money for their debate team. Roger sold 1/3 as much candy as Sally did. If Sally sold 2 9/10 boxes of candy, how many boxes of candy did Roger sell?
Answers
The boxes of candy sold by Roger are 29/30.
According to the question,
We have the following information:
Roger sold 1/3 as much candy as Sally sold.
Sally sold [tex]2\frac{9}{10}[/tex] boxes of candy.
Now, first we will convert the boxes of candy sold by Sally from the mixed fraction.
(More to know: there are three kinds of fraction: mixed fraction, proper fraction and improper fraction. We need to change mixed fraction in most of the cases to solve the questions further.)
We have:
29/10
Now, we know that the boxes of candy sold by Roger is 1/3 of 29/10.
So, we have the following expression:
[tex]\frac{1}{3}* \frac{29}{10}[/tex]
29/30

To solve this question, you have to look for the answers in the table.
Let's analise each part of the question to solve it:
(a) f(1) =
f(1) means the output of the function [f(x)] when x = 1.
Looking for x =1 in the table, you can see that f(x) = 0.
f(1) = 0.
(b) f(x) = 3, x =
Now, you have to find the input (x) when the outpout [f(x)] is 3.
Looking for f(x) = 3, you can see that x = 7.
f(x) = 3, x = 7.
(c) f⁻¹(0) =
Now, you have to evaluate the inverse function.
To look for the values of the inverse function, x will be the output and f⁻¹ will be the input.
To look for f⁻¹(0), look for f(x) = 0 (input) and the output will be 1
f⁻¹(0) = 1.
(d) f⁻¹(x) = 7; x =
Again, you have an inverse function. So, 7 will be the input in the table (x). x is 7 (output).
f⁻¹(x) = 7; x = 3.

A cardboard box, which weighs 0.6 pound when empty, is filled with 15 bags of beans and a 4-pound bag of rice. The total weight of the box and the contents inside it is 25.6 pounds. One way to represent this situation is with the equation 0.6 + 15b + 4 = 25.6.
What does the solution represent in this situation?
Answers
The solution b = 1.4 represents the weight of one bag of bean.
In the question;
it is given that
weight of cardboard box when empty = 0.6 pounds
number of bean bags = 15 bags
weight of rice bag = 4 pounds
let the number of bean bags = b
total weight of carboard box with contents= 25.6 pounds
So , according to the question
0.6 + 15b + 4 = 25.6
solving further , we get
15b+4.6 = 25.6
15b = 25.6-4.6
15b = 21
b = 21/15
b = 1.4
Therefore , the solution b = 1.4 represents the weight of one bag of bean.

When the summer started, Janie needed to fill her empty pool. At first, she used a garden hose to fill the pool, but this was taking too long. She got tired of watching the pool fill so slowly, so she turned off the water and went for a walk. She spotted a truck in the neighborhood that was filling pools and flagged them down to come fill her pool too. They were able to fill the pool at a faster rate. Which graph best represents this situation?
Answers
The statement mentions that the pool started empty, which implies that the graph must start at the point (0,0).
Then, the pool slowly filled, so the amount of water in the pool remained constant when Janie turned off the water and went for a walk.
Finally, thanks to a truck in the neighborhood the pool filled up quickly, and when it was filled the amount of water remained constant.
Therefore, the graph that best represents this situation is the one shown in option B.

2) Then the other angle, has the same measure 50º since this is an isosceles triangle, at least two congruent sides, and two congruent angles.
We can finally write
x+88 +50 +50 = 180
x +188 =180 subtract 188 from both sides

Hello there. To solve this question, we'll have to remember some properties about trigonometric functions and the right triangle.
We want to find x such that:
[tex]\tan (x)=\sqrt[]{3}[/tex]We'll use the second right triangle to show what we want.
First, given a triangle:
We know that the hypotenuse will be:
[tex]\sqrt[]{x^2+y^2}[/tex]But most importantly, the tangent of the angles α and β can be calculated by only using the legs of the triangle: it is the ratio between the opposite side and the adjacent side to an angle.
[tex]\tan (\alpha)=\frac{y}{x}[/tex]and
[tex]\tan (\beta)=\frac{x}{y}[/tex]Now look at the triangle we have:
We can easily check that:
[tex]\sqrt[]{3}=\frac{\sqrt[]{3}}{1}[/tex]So it would be good to find something that relates the ratio between those two numbers: the tangent of 60º!!
Therefore, we have:
[tex]\tan (60^{\circ})=\frac{\sqrt[]{3}}{1}=\sqrt[]{3}[/tex]And the solution to x is:
[tex]x=60^{\circ}[/tex]The sum of an integer and 2 times the next consecutive even integer is -2. Find the value of the lesser integer.
Answers
The value of the lesser integer is -2.
According to the question,
We have the following information:
The sum of an integer and 2 times the next consecutive even integer is -2.
Let's take the lesser integer to be x.
Now, the next consecutive integer will be (x+2).
So, we have the following expression:
x + 2(x+2) = -2
x+2x+4 = -2
3x+4 = -2
Moving 4 from the left hand side to the right hand side will result in the change of the sign from plus to minus:
3x = -2-4
3x = -6
x = -6/3
x = -2
Hence, the value of the lesser integer is -2.

Answers
Answer:
sin2x = 16/65
cos2x = -63/65
tan2x = -16/63
Explanation:
the tangent of an angle is equal to the opposite side over the adjacent side. So, if the tan(x) = 8, we can represent this as the following diagram:
Therefore, we can calculate the value of the hypotenuse as:
[tex]\text{Hypotenuse = }\sqrt[]{8^2+1^2}=\sqrt[]{64+1}=\sqrt[]{65}[/tex]With the hypotenuse, we can calculate sin(x) and cos(x) as follows:
[tex]\begin{gathered} \sin x=\frac{Opposite}{hypotenuse}=-\frac{8}{\sqrt[]{65}} \\ \cos x=\frac{\text{Adjacent}}{\text{hypotenuse}}=-\frac{1}{\sqrt[]{65}} \end{gathered}[/tex]We type the negative sign because the question says that sin(x) is negative.
Now, we will use the following trigonometric identities to find sin(2x), cos(2x) and tan(2x)
[tex]\begin{gathered} \sin 2x=2\sin x\cos x \\ \cos 2x=1-2\sin ^2x \\ \tan 2x=\frac{2\tan x}{1-\tan ^2x} \end{gathered}[/tex]Therefore, replacing the values, we get:
[tex]\sin 2x=2(\frac{-8}{\sqrt[]{65}})(\frac{-1}{\sqrt[]{65}})=\frac{16}{65}[/tex][tex]\cos 2x=1-2(\frac{-8}{\sqrt[]{65}})^2=1-2(\frac{64}{65})=-\frac{63}{65}[/tex][tex]\tan 2x=\frac{2(8)}{1-8^2}=-\frac{16}{63}[/tex]So, the answers are:
sin2x = 16/65
cos2x = -63/65

The time Nancy spent working on her ela homework is equal to 2 hours.
The time Nancy spent working on her ela homework can be calculated by multiplication.
We can calculate it by multiplying the fraction of time spent by her on ela homework by the total time she spent on her homework.
As the total time spent by her on homework is 2 1/2 hours we can covert it into decimals as;
2 1/2 = 5/2 = 2.5 hours
Now multiplying it by the fraction of her time spent on ela homework,
Time spent on ela homework = 4/5 × 2.5
Time spent on ela homework = 10/5
