Sylvia has 3/4 of a yad of paper to wrap candles. It takes 1/8 of a yard of paper to wrap each candle. How many candles can Sylvia Wrap?
Answers
Sylvia can wrap 6 candles.
To find out how many candles Sylvia can wrap with 3/4 of a yard of paper, we need to divide the total paper by the paper needed for each candle. Since it takes 1/8 of a yard to wrap one candle, we can find the number of candles by dividing 3/4 by 1/8:
3/4 ÷ 1/8 = 3/4 x 8/1 = 6 candles
Therefore, Sylvia can wrap 6 candles with the available paper.
Which statements are correct steps in finding the linear equation of a line that passes through the points (−1, 7) and (2, 4) using the point-slope form method? Select all that apply.
Answers
Answer:
y – 4 = –1 (x – 2)
y – 7 = –1 (x – (–1))
y = –x + 6
Step-by-step explanation:
To find the linear equation using the point-slope form method, determine the slope and substitute the coordinates into the formula.
Explanation:To find the linear equation of a line that passes through the points (-1, 7) and (2, 4) using the point-slope form method, follow these steps:
Determine the slope using the formula: slope = (y2 - y1) / (x2 - x1)Choose one of the given points and substitute the coordinates into the point-slope formula: y - y1 = m(x - x1)Simplify the equation to get the linear equation in point-slope formUsing these steps, the correct options are:
a. Find the slope using the formula: m = (4 - 7) / (2 - (-1))
b. Substitute the coordinates (2, 4) into the point-slope formula: y - 4 = m(x - 2)

Answers
Answer:
Wilhem
Step-by-step explanation:
The given equation is
[tex]32g+8g-10g=150[/tex]
Step 1 : Add 32g and 8g.
[tex](32g+8g)-10g=150[/tex]
[tex](32+8)g-10g=150[/tex]
[tex]40g-10g=150[/tex]
Step 2: Subtract 10 from 40.
[tex](40-10)g=150[/tex]
[tex]30g=150[/tex]
Step 3: Divide both sides by 30, find the value of g.
[tex]\frac{30g}{30}=\frac{150}{30}[/tex]

The value of g is 5.

xfinity cable charges $60 set up fee and $80 a month for cable. direct tv has. a $160 equipment fee and $79 a month for cable services. How many months will it take before the cost is the same? What is that cost?
Answers
The correct answer is 100 months, 8060$,
To solve this problem, we need to find the point where the total cost of Xfinity cable and Direct TV cable services become equal, and then calculate the corresponding cost at that point.
Given:
- Xfinity cable charges a [tex]$60[/tex] setup fee and [tex]$80[/tex] per month.
- Direct TV charges a [tex]$160[/tex] equipment fee and [tex]$79[/tex] per month.
Let's define the total cost functions for both cable services:
Xfinity cable total cost ([tex]C_x[/tex]) after x months:
[tex]C_x = 60 + 80x[/tex]
Direct TV total cost ([tex]C_d[/tex]) after x months:
[tex]C_d = 160 + 79x[/tex]
To find the point where the total costs are equal, we set the two equations equal to each other and solve for x:
[tex]60 + 80x = 160 + 79x[/tex]
[tex]x = 100[/tex]
Substituting x = 100 into either equation, we can find the total cost at that point:
[tex]C_x = 60 + 80(100) = 8060[/tex]
[tex]C_d = 160 + 79(100) = 8060[/tex]
Therefore, after 100 months, the total cost of both cable services will be the same at [tex]$8060[/tex].

The vertices of triangle ABC are A(2,3), B(–1,2), and C(3,1). If ΔDEF ∼ ΔABC and DE = 4AB, what is the length of EF? √10
Answers
Answer:
The length of EF is [tex]4\sqrt{17}[/tex] units.
Step-by-step explanation:
The vertices of triangle ABC are A(2,3), B(–1,2), and C(3,1).
Using distance formula:
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]BC=\sqrt{(3+1)^2+(1-2)^2}=\sqrt{17}[/tex]
It is given that ΔDEF ∼ ΔABC.
If two triangles are similar then the corresponding sides are proportional.
[tex]\frac{AB}{DE}=\frac{BC}{EF}[/tex]
[tex]\frac{AB}{4AB}=\frac{BC}{EF}[/tex] (DE = 4AB)
[tex]\frac{1}{4}=\frac{BC}{EF}[/tex]
[tex]EF=4\times BC[/tex]
[tex]EF=4\times \sqrt{17}[/tex]
[tex]EF=4\sqrt{17}[/tex]
Therefore the length of EF is [tex]4\sqrt{17}[/tex] units.

Should the number of people in different cities be represented on a graph as one-dimensional, two-dimensional, or three-dimensional?
A. one-dimensional
B. two-dimensional
C. three-dimensional
Answers
The number of people in different cities should be represented on a graph as Two-dimensional.
I'll explain why: The number of dimensions you need on a graph is equal to the number of variables that you are studying. In this case, you have two variables in the study:
1)The number of people
2)The city where they live
You'll need a two-dimensional graph with two axes in which one of the axes represents the number of people and the other axis represents the city. If you were also studying the age of those people, you'll need one more dimension to include this new variable.

An app developer projects that he will earn $22.00 for every 8 apps downloaded. Write an equation to represent the proportional relationship between the number of apps and the total earnings.
Answers
Answer:
y = ($2.750 / app) . x
Step-by-step explanation:
Let's call
x = number of appsy = earned moneyThere is a linear relation between x and y, that follows the general form:
y = a . x + b
where
a is the slope
b is the y-intercept
The slope is:
Δy / Δx = $22.00 / 8 app = $2.750 / app
The, we have
y = ($2.750 / app) . x + b
When x = 0 (no app has been sold), y = 0 (no money has been earned).
0 = ($2.750 / app) . 0 + b
b = 0
The equation representing the proportionality between x and y is:
y = ($2.750 / app) . x

13. Multiply the first equation by -4 and add the second.
.. -4(4x -3y) +(16x +10y) = -4(16) +240
.. 22y = 176
.. y = 8
.. x = (16 +3*8)/4 = 10
(x, y) = (10, 8)
14. Divide the first equation by 2, multiply the second by 2, and add.
.. (20x +10y)/2 +2(-5x +4y) = (100)/2 +2(53)
.. 13y = 156
.. y = 12
.. x = (53 -4*12)/-5 = -1
(x, y) = (-1, 12)
18. Multiply the first equation by -2 and the second by 3, then add.
.. -2(3x -5y) +3(2x -3y) = -2(-16) +3(-8)
.. y = 8
.. x = (-16 +5*8)/3 = 8

A candidate to the presidency wants to know what percentage of the registered voters in the country would vote for him. So, he gives that task to one of his aides and tells him he has 3 days to come up with the results. Describe a method the aide should use to complete the task in time and which provides meaningful data. Use size of the sample, population of interest, and method of selection to complete your answer.
Answers
Answer:
Since the aide has only 3 days to come up with the results So, firstly he will collect the data of those people only who has the right to vote which is called the population of interest.
The size of the sample will depend on the population of the country.
Finally, for method of selection, a random and wide range of people must be surveyed. Ideally, he would want people from different professions, age groups, political parties, and geographical locations.
Since the aide has only 3 days, the most practical decision may be to use online surveys spread around varying interest groups to collect the information in the given short period of time. Because it is very difficult to collect this information in a very short period of time.
