The lines represented by the equations by - x = 5 and y = { x = 1 are
are they parallel or perpendicular
Answer:
Parallel
Step-by-step explanation:
Let the required lines be y-x = 5 and y = x-1
If y-x = 5
y = x + 5
The slope m = 1
For the line y = x - 1
The slope m is also 1
Since the slope of both lines are the same, hence both liens are parallel

Danielle constructs a scale model of a building with a rectangular base. Her model is 2 inches in length and 1 inch in width. The scale on the model is 1 inch = 47 feet. What is the actual area, in square feet, of the base of the building? in ft2
Answer: The actual area of the base of the building = 4418 square feet.
Step-by-step explanation:
Dimensions of model: 2 inches in length and 1 inch in width.
The scale on the model is 1 inch = 47 feet.
Actual length = 2 x (47 feet) = 94 feet
Actual width = 1 x 47 feet = 47 feet
Actual area of base of building = (Actual length) x (Actual width)
= 94 x 47 square feet
= 4418 square feet
Hence, the actual area of the base of the building = 4418 square feet.

Answer:
46
Step-by-step explanation:
180-134=46
Answer:
They're both 46 degrees
Step-by-step explanation:
Angle b and 134 are right next to each other so they're supplementary and have to equal 180 degrees.
180-134=46, and since Angle c is is a vertical angle with Angle b, it also equals 46^^

(a) Order the popularity of the choices from greatest to least.
(b) It was estimated that 360 people were surveyed. If this was true, how many people would have voted for Ehrnhardt? Round to the nearest whole number. Show your work.
(c) 65 people voted for Petty. Was the estimate of total voters from Part (b) accurate? Explain.
Answer:
(a) Earnhardt (40%), Gordon (29%), Waltrip (18%), and Petty (13%)
(b) 144, work is below
(c) No
Step-by-step explanation:
(b)
convert 40% to a decimal by dividing by 100 = 0.4
360 x 0.4 = 144 people voted for Earnhardt
(c) converting Petty's percentage to a decimal, we get 0.13. 360 x 0.13 = 46.8, or 47 people, not 65.
Waltrip's percentage, 0.18 x 360 = 64.8, or 65 people.

400-36v^2 can someone find the factor?
Answer:
-4(3v - 10)(3v + 10)
Step-by-step explanation:
You must find the factored form of 400 - 36v^2.
You can rearrange this to - 36v^2 + 400 to make it less confusing.
So you have - 36v^2 + 400.
The next step is to see what you can take out of this. You can take out a GCF, a greatest common factor. This is basically a number that goes into both 36 and 400. This number is 4.
36 / 4 = 9 and 400 / 4 = 100.
Since it is a negative 36, you need to take out a negative 4.
So you put a 4 outside parenthesis and divide - 36 / 4 and 400 / 4.
-4(9v^2 - 100).
Now you must factor the inside of the parenthesis.
9v^2 - 100.
This is the same as 9v^2 + 0v - 100.
What are 2 numbers that multiply to get -100 and add to get 0?
These numbers are -10 and +10.
2 terms that multiply together get 9v^2 are 3v and 3v.
So the answer is:
-4(3v - 10)(3v + 10).
This is the factored form.

Answer:

Step-by-step explanation:
14+35=49 and we are looking for the number times 7 that gives us 49.
So, we already have 2. 2+ what times 7 gives us 49? 2 + 5 = 7 and so now our equation looks like this:
14+35 =7 (2+5)
Or
14+35= 7x7 becuase 7x7 is 49 and 14+35 is also 49.

Label ABC with the following information.
m/A = 21°
AC = 13
Find BC.
Answer:
BC = 4.7
Step-by-step explanation:
From the question given above, the following data were:
Angle A = 21 °
Hypothenus = AC = 13
Opposite = BC =?
The length of BC can be obtained by using sine ratio as illustrated below:
Sine A = Opposite /Hypothenus
Sine 21 = BC / 13
0.3584 = BC / 13
Cross multiply
BC = 0.3584 × 13
BC = 4.7
Thus, the length of BC is 4.7

Ms. Green has 18 pencils at her desk. Students borrow some of the pencils, and 6 pencils are left at the end of the school day. How many pencils were borrowed?
x - 6 = 18
18 - x = 6
18 + 6 = x
Answer:
18-x=6
Step-by-step explanation:
because
if you have eighteen and some were borrowed and 6 were left so it will be subtracted
Answer:
18 - x = 6
Step-by-step explanation:
In any equation x is the unkown you are trying to figure out.
In a word-problem-solving question its helpful to set out what you know and what you dont know:
You know the original number of pens = 18
You know the final number of pens = 6
You dont know how many pens were taken.
Therefore x is the difference between 18 and 6.
18 pens take away x pens is equal to 6
hence 18 - x =6

The measure of the minor arc BC is 63º. What is the measure of ZBAC?
Answer:
measure or arc BAC should be 297 degrees (with assumptions)
Step-by-step explanation:
Assumption 1: the cap Z in your question is actually an angle symbol
Assumption 2: A is the center of the circle

Answer:
The three gallon container is the better buy. See below.
Step-by-step explanation:
8 pints
2 pints = 1 quart.
8 pints = 4 quarts.
4 quarts = 22.64 Divide by 4
1 quart = 5.66
3 gallons.
1 gallon = 4 quarts
3 gallons = 12 quarts.
The cost of 1 quart = 54.48/12 = 4.54
2x + 3y = 5x - y
Complete the missing value in the solution to the equation.
( _ , 0 )
Answer:
(4y/3, 0) or if there are no options, it's probably (0, 0)
Step-by-step explanation:
2x + 3y = 5x - y
So we are trying to find the missing value in the solution (_, 0)
We are looking for the x-intercept/root if the coordinate is in this way: (_, 0)
So to find the root, We are solving for x
2x + 3y = 5x - y
First, subtract 5x from bth sides
2x + 3y - 5x = 5x - y - 5x
2x + 3y - 5x = -y
Add like terms
-3x + 3y = -y
Now, subtract 3y from both sides
-3x + 3y - 3y = -y - 3y
-3x = -4y
Divide both sides by -3
-3x/-3 = -4y/-3
x = -4y/-3
We are not done yet because the answer above is not quite right. A negative number divided by a negative number results in a positive number.
So x = 4y/3
Now that we found x, we can input it to the coordinate
(4y/3, 0)

How do you find the area of the shaded sector of the circle? The radius is 10in and the sector is 45 degrees
Given:
Radius of the circle = 10 in
Central angle of the sector = 45 degrees
To find:
The area of the sector.
Solution:
Area of a sector is
[tex]A=\dfrac{\theta}{360^\circ}\pi r^2[/tex]
Where, [tex]\theta[/tex] is the central angle in degrees.
Putting r=10 and [tex]\theta=45^\circ[/tex], we get
[tex]A=\dfrac{45^\circ}{360^\circ}\pi (10)^2[/tex]
[tex]A=\dfrac{1}{8}\pi (100)[/tex]
[tex]A=12.5\pi[/tex]
Therefore, the area of the sector is 12.5π sq. inches.
