A car has a 16-gallon fuel tank. When driven on a highway, it has a gas mileage of 30 miles per gallon. The gas mileage (also called "fuel efficiency") tells us the number of miles the car can travel for a particular amount of fuel (one gallon of gasoline, in this case). After filling the gas tank, the driver got on a highway and drove for a while.
How many miles has the car traveled if it has the following amounts of gas left in the tank (15 galllons)?
Answer:
30
Step-by-step explanation:
The car has travelled for 30 miles.
Amount of gallons in fuel tank = 16 gallons
Gas mileage = 30 miles per gallon.
Since the driver has 15 gallons left, the number of miles that the car traveled will be:
= (16miles - 15 miles) × 30
= 1 mile × 30
= 30 miles
The car travelled for 30 miles.

what is the equation of the line that passes through the point (-2,-2) and is parallel to the line 3x-y=2
Answer:
y = 3x + 4
Step-by-step explanation:
Turn the equation from standard form to slope intercept form. So, solve for y.
3x - y = 2
~Subtract 3x to both sides
-y = 2 - 3x
~Divide -1 to everything
y = -2 + 3x
~Reorder
y = 3x - 2
The slope of a parallel line is the same as the original.
Find the new y-intercept.
y = 3x - 2
-2 = 3(-2) + b
-2 = -6 + b
4 = b
y = 3x + 4
Best of Luck!
What is the slope of the line that passes through the points (8, 8)(8,8) and (20, -2) ? (20,−2)? Write your answer in the simplest form.
Answer: -5/6
Step-by-step explanation:
slope formula m=(y2-y1)/(x2-x1)
m=(-2-8)/(20-8)
m=-10/12
(simplify) m=-5/6
The slope value in the simplest form of a line that passes through (8, 8) and (20, -2) is: [tex]\mathbf{-\frac{5}{6}}[/tex]
Recall:
Slope (m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
Thus:
Given two points that a line passes through as: (8, 8) and (20, -2),
Let,(8, 8) = [tex](x_1, y_1)\\\\[/tex]
(20, -2) = [tex](x_2, y_2)[/tex]
Plug in the values into the slope (m) formulaSlope (m) = [tex]\frac{-2 - 8}{20 - 8}[/tex]
Slope (m) = [tex]\frac{-10}{12}[/tex]
Simplify the fractionSlope (m) = [tex]\mathbf{-\frac{5}{6}}[/tex]
Therefore, the slope value in the simplest form of a line that passes through (8, 8) and (20, -2) is: [tex]\mathbf{-\frac{5}{6}}[/tex]

Motorcycle travel 90 mph accelerates to pass a truck five seconds later the car is going 120 mph calculate the acceleration
Answer:
Explanation:
Let Vc be the velocity of the car and I'm the velocity of the motorcycle. If we convert their given values, we get:
Vc = 87 km/h * 1000m / 1km * 1h / 3600s = 24.17m/s
Vm = 95 km/h * 1000m / 1km * 1h / 3600s = 26.38m/s
Since their positions are equal after 17s we can stablish that:
Where d is the initial separation distance of 54m. Solving for a, we get:

In Orlando, Florida, there are an average of 24 days of rain each June. What percent of the month of June experiences rain?
Answer:
80%
Step-by-step explanation:
Set up a proportion: [tex]\frac{24}{30} = \frac{x}{100}[/tex] Cross multiply, then divide: 100 × 24 = 2400, 2400 ÷ 30 = 80So, x equals 80.80/100 = 80%I hope this helps!
The percentage of the month of June that experiences rain is 80%.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of days in June = 30.
Number of days in June that rains = 24
Now,
The percentage of days that rain in June.
= 24/30 x 100
= 80%.
Thus,
80% of the days in June rain.

The scale of a map says that 8cm represents 5km what is the actual number of kilometers that is represented by 5 centimeters on the map
Answer:
8 km
Step-by-step explanation:
It is given that, the scale of a map says that 8 cm represents 5 km. We need to find the actual number of kilometers that is represented by 5 centimeters on the map.
8 cm = 5 km
1 cm = (8/5) km
For 5 cm, multiply (8/5) km by 5.
So,
x = 8 km
So, 8 km is represented by 5 centimeters on the map.

-px+r=8x-2 slove for x
Step-by-step explanation:
-px + r = 8x -2
Step 1: Add -8x to both sides.
-px + r + -8x = 8x - 2 + -8x
-px + r - 8x = 2
Step 2: Add -r to both sides.
-px + r - 8x + -r = -2 + -r
-px - 8x = -r - 2
Step 3: Factor out variable x.
x(-p - 8) = -r - 2
Step 4: Divide both sides by -p - 8.
x(-p - 8) = -r - 2
-p - 8 -p - 8
Answer
x = r + 2

A regular pentagon is centered about the origin. Which transformation
maps the pentagon onto itself?

b. A reflection across the x-axis
C.
d.
A clockwise rotation of 144 degrees about the origin
Answer:
The answer is D. A clockwise rotation of 144 degrees about the origin.
Step-by-step explanation:
In most cases; when an object is transformed, the position of the object changes. A clockwise rotation of 144 degrees about the origin will map the pentagon onto itself.
Given:
The attached pentagon
The number of sides (n) in a pentagon is:
[tex]n = 5[/tex]
The pentagon will not be mapped onto itself when reflected across line m because m is not at the center of the polygon
The pentagon will not be mapped onto itself when reflected across the x-axis because the pentagon has 5 sides (odd number of sides)
To map the pentagon onto itself, the pentagon has to be rotated.
The angle of rotation is:
[tex]\theta = \frac{360}n[/tex]
[tex]\theta = \frac{360}5[/tex]
[tex]\theta = 72[/tex]
Other possible angles of rotation must be a multiple of 72. i.e.
[tex]\theta = 72, 144, 216, 288....[/tex]
This means that: option (d) is correct because 144 is a multiple of 72
Hence, a clockwise rotation of 144 degrees about the origin will map the pentagon onto itself.

An alien blob started with a mass of 18 kg and is doubling in size every day. How large will the blob be after 2 weeks? y= a(b).
Answer:
214kg
Step-by-step explanation:
We can use the equation [tex]f(x)=(x)^2+18[/tex] to model the blobs growth. There are 14 days in 2 weeks so if we plug in [tex]f(14)[/tex] that will give us [tex]f(14) = (14)^2+18\\f(14)=214[/tex] so the blob will be 214kg in 2 weeks.
Alex bought home a 7 11/12 foot tree. When he got it home,he cut 1 2/3 off of it. How tall is the tree after he cut it down
Given:
Initial height of tree = [tex]7\dfrac{11}{12}[/tex] foot
He cut [tex]1\dfrac{2}{3}[/tex] off of tree.
To find:
The remaining height of tree after cut.
Solution:
Initial height of tree is
[tex]7\dfrac{11}{12}=\dfrac{7\times 12+11}{12}[/tex]
[tex]7\dfrac{11}{12}=\dfrac{84+11}{12}[/tex]
[tex]7\dfrac{11}{12}=\dfrac{95}{12}[/tex]
He cut [tex]1\dfrac{2}{3}[/tex] off of tree.
[tex]1\dfrac{2}{3}=\dfrac{1\times 3+2}{3}[/tex]
[tex]1\dfrac{2}{3}=\dfrac{3+2}{3}[/tex]
[tex]1\dfrac{2}{3}=\dfrac{5}{3}[/tex]
Now,
Remaining height = Initial height - cut
[tex]=\dfrac{95}{12}-\dfrac{5}{3}[/tex]
[tex]=\dfrac{95-20}{12}[/tex]
[tex]=\dfrac{75}{12}[/tex]
[tex]=\dfrac{25}{4}[/tex]
[tex]=\dfrac{6\times 4+1}{4}[/tex]
[tex]=6\dfrac{1}{4}[/tex]
Therefore, the remaining height of the tree is [tex]6\dfrac{1}{4}[/tex] foot.
