The advertising sticker on Allen's
new car says it gets 36 miles per
gallon on the highway. The graph
represents the actual relationship
between the number of miles Allen
drove on the highway and the
gallons of gasoline his new car used.
How does the advertised gas
consumption rate compare to the
actual rate?
Answer:
Step-by-step explanation:
The rate in this case is slope of the line. The formula of a slope is m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
(10, 325)
(4, 130)
m = [tex]\frac{325-130}{10-4}[/tex] = [tex]\frac{195}{6}[/tex] = 32.5 miles per gallon
The actual rate is less (better) than advertising.

Daniela has 2 1/4 basketball games left to play in a tournament, and she has 3/4 gallon of water left to drink. If she drinks the same amount of water each game, how much water can she drink each game? *
Answer:
1/3 gallons of waterStep-by-step explanation:
If Daniela has 2 1/4 basketball games left to play in a tournament, and she has 3/4 gallon of water left to drink, since she drinks the same amount in each game, we can say;
2 1/4 games = 3/4 gallons
To calculate how much he has to drink in a game, this can be expressed as;
1 game = x gallon
Solve for x;
2 1/4 games = 3/4 gallons
1 game = x gallon
Cross multiply
3/4 = 2 1/4x
3/4 = 9/4 x
9x/4 = 3/4
cross multiply;
9x * 4 = 4*3
36x = 12
x = 12/36
x = 1/3
Hence she can drink 1/3 gallons of water in each game.

Solve for x and y please
Answer:
x = 20°
y = 19°
Step-by-step explanation:
The first two angles that are in the 2nd Quadrant:
2x - 3
3x - 7
The rule states that the two angles are complimentary angles that form an angle of 90°. So,
(2x - 3) + (3x - 7) = 90
2x - 3 + 3x - 7 = 90
2x + 3x - 3 - 7 = 90
5x - 10 = 90
5x = 90 + 10
5x = 100
x = 100 ÷ 5
x = 20
Another rule applies here, vertical angles are equivalent to each other.
So,
2x - 3 = 2y - 1
2(20) - 3 = 2y - 1
40 - 3 = 2y - 1
37 = 2y - 1
37 + 1 = 2y
38 = 2y
38 ÷ 2 = y
19 = y
1. The rent of a condo unit was ₱1,200.00 for one night, to be shared equally by a group of female friends, who will be having their get together in the condo unit. At the last minute, four people decided not to go to the party, thus raising the cost to each girl by ₱400.00. How many girls attended the get-together?
(With Solutions Please)
Answer:
6 girls were there are first
Step-by-step explanation:
use trial and error. divide 1200 by a random number like 10, and see how much they each had to pay. If we guessed 10, then each girl would hypothetically pay 120 pounds. If four girls left, then 1200/6 would be 200 pounds. there was only a 60 pound increase here, not a 400 pound one.
I checked 1200/6 which equals 200 pounds per girl. If 4 girls left, then it would be 600 pounds for the 2 remaining girls. the rent increased from 200 to 600 which is a 400 pound increase.
Which expression is equivalent to 2(8n)^4
Answer:
2. 8n. 8n. 8n. 8n
Step-by-step explanation:
[tex]2 {(8n)}^{4} = 2. 8n. 8n. 8n. 8n[/tex]
Equivalent expressions are expressions with equal value.
The equivalent expression of [tex]\mathbf{2\cdot(8n)^4}[/tex] is [tex]\mathbf{2\cdot(8n)\cdot(8n)\cdot(8n)\cdot(8n)}[/tex]
The expression is given as:
[tex]\mathbf{2\cdot(8n)^4}[/tex]
Apply law of indices
[tex]\mathbf{2\cdot(8n)^4 = 2\cdot(8n)\cdot(8n)\cdot(8n)\cdot(8n)}[/tex]
The above equation means that:
[tex]\mathbf{2\cdot(8n)\cdot(8n)\cdot(8n)\cdot(8n)}[/tex] is equivalent to [tex]\mathbf{2\cdot(8n)^4}[/tex]
Hence, the correct option is (d) [tex]\mathbf{2\cdot(8n)\cdot(8n)\cdot(8n)\cdot(8n)}[/tex]

How to solve the triangle given one angle and 2 sides. I want help solving the problem not just an answer, thanks.
A. Use the law of cosines:
29² = 34² + c ² - 2•34•c cos(30.3°)
Use a calculator to solve for c ; notice this equation is quadratic, you get two possible solutions, c ≈ 5.973 ≈ 6 or c ≈ 52.738 ≈ 53.
Then use the law of sines to solve for the two possibles measures of angle C :
sin(30.3°)/29 = sin(C )/c
sin(C ) = c sin(30.3°)/29
sin(C ) ≈ 0.1039 or sin(C ) ≈ 0.9175
C ≈ 6.0° or C ≈ 66.6°
The interior angles of any triangle sum to 180°, so the remaining angle has measure either
B = 180° - 30.3° - C
B ≈ 143.7° or B ≈ 83.1°
So to recap,
B ≈ 143.7°, C ≈ 6.0°, c ≈ 6
and
B ≈ 83.1°, C ≈ 66.6°, c ≈ 53

Answer:
The answer is
[tex] \huge y = - 2x[/tex]
Step-by-step explanation:
To find an equation of a line when given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
From the question we have
[tex]y + 4 = - 2(x - 2) \\ y + 4 = - 2x + 4 \\ y = - 2x + 4 - 4[/tex]

a line passes through the point (-8,6) and has a slope of 3/4 in general form
Answer:
y = 3/4x + 12
Step-by-step explanation:
let equation of the line be y = 3/4x + b
sub (-8, 6):
6 = 3/4(-8) + b
12 = b
therefore equation of the line is y = 3/4x + 12

Answer:
General Form of Equation of a line that passes through the point (-8,6) and has a slope of 3/4 is:
[tex]\frac{3}{4}x-y+12=0[/tex]
Step-by-step explanation:
We need to find equation of line that passes through the point (-8,6) and has a slope of 3/4 in general form.
The general form of linear equation is [tex]Ax+By+C=0[/tex]
First we will use slope-intercept form i.e, [tex]y=mx+b[/tex] to find equation and then write it in general form.
Where m is slope and b is y-intercept.
We are given slope = 3/4 but y-intercept is not given and we need to find.
Finding y-intercept
Using the point (-8,6) and slope m = 3/4 we can find y-intercept
[tex]y=mx+b\\6=\frac{3}{4}(-8)+b\\6=3(-2)+b\\6=-6+b\\b=6+6\\b=12[/tex]
So, y-intercept b is 12
Equation of line
The line has slope m=3/4 and y-intercept b is 12, the equation is:
[tex]y=mx+b\\y=\frac{3}{4}x+12[/tex]
General Form of Equation of a line that passes through the point (-8,6) and has a slope of 3/4 is:
[tex]\frac{3}{4}x-y+12=0[/tex]

1.11111 as a fraction
Answer:
Answer:
1.11111=111111100000
Showing the work
Rewrite the decimal number as a fraction with 1 in the denominator
1.11111=1.111111
Multiply to remove 5 decimal places. Here, you multiply top and bottom by 105 = 100000
1.111111×100000100000=111111100000
Simplify the improper fraction,
=111111100000
In conclusion,
1.11111=111111100000
Step-by-step explanation:
The fraction equivalent of the repeating decimal 1.11111 is 10/9. This means that 1.11111 is equivalent to 10/9, indicating a ratio of 10 parts to 9 parts. Simplifying the fraction ensures that it is in its simplest form with no common factors between the numerator and the denominator other than 1.
To express the decimal 1.11111 as a fraction, we can use algebraic manipulation. Let's denote the repeating decimal as x:
x = 1.11111...
To eliminate the repeating part, we can multiply x by 10:
10x = 11.11111...
Now, we can subtract the original equation from the multiplied equation to eliminate the repeating part:
10x - x = 11.11111... - 1.11111...
Simplifying the equation:
9x = 10
Dividing both sides by 9:
x = 10/9
Therefore, the fraction equivalent of the repeating decimal 1.11111 is 10/9. This means that 1.11111 is equivalent to 10/9, indicating a ratio of 10 parts to 9 parts. Simplifying the fraction ensures that it is in its simplest form with no common factors between the numerator and the denominator other than 1.
