Hannah's gas tank is 60% full and has 9 gallons of gas. How
many gallons does Hannah's gas tank hold?
Your uncle just bought a hybrid car and wants to take you and your siblings camping. Before you leave for the trip your uncle fills up the car with 18 gallons of gas. After driving for 1 hour there are 16.5 gallons of gas left in the tank.
Solve this equation
2 x + 3 = x - 4
Answer:
-7
Step-by-step explanation:
2x + 3 = x - 4
so you first add four to both sides of the equal sign:
2x + 3 = x - 4
+ 4 + 4
making the equation:
2x + 7 = x
you now subtract 2x from both sides:
2x + 7 = x
-2x - 2x
to get:
7 = -1x
you then divide both sides by -1:
7/-1 = -1x/-1
to get:
-7 equals x or x = -7
Milan will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $48 and costs an additional $0.20 per mile driven. The
second plan has an initial fee of $57 and costs an additional $0.15 per mile driven.
For what amount of driving do the two plans cost the same?
What is the cost when the two plans cost the same?
If you do not have both of the answers do not bother to reply.
For 180 miles of driving the two plans will cost the same, at a price of $84.
Step-by-step explanation:1 - Set up the system of equations
Let x represent the miles driven
Let y represent the cost
First Plan:
y = $48 + $0.20x
Second plan:
y = $57 + $0.15x
Note that both are set equal to y, that means we can substitute y in one equation with the other equation because y = y
2 - Substitute
$57 + $0.15x = y = $48 + $0.20x
$57 + $0.15x = $48 + $0.20x
3 - Get the variables on one side and the constants on the other and then get x alone
$57 + $0.15x = $48 + $0.20x
- $48 - $48
$9 + $0.15x = $0.20x
- $0.15x - $0.15x
$9 = $0.05x
$9/0.05 = $0.05x/0.05
x = 180 Miles
"For what amount of driving do the two plans cost the same?
For 180 miles of driving the two plans will cost the same.
4 - Plug 180 in for x in either equation and solve to find the cost at which they equal
y = $48 + $0.20x
y = $48 + $0.20(180)
y = $48 + $36
y = $84
"What is the cost when the two plans cost the same?"
$84 is the cost when the two plans cost the same

If the marginal revenue (in dollars per unit) for a month is given by MR = −0.5x + 400, what is the total revenue from the production and sale of 30 units?
Given:
Marginal revenue (in dollars per unit) for a month is
[tex]MR=-0.5x+400[/tex]
To find:
The total revenue from the production and sale of 30 units.
Solution:
We know that, total revenue is integration of marginal revenue with respect to quantity.
[tex]TR=\int MR dx[/tex]
[tex]TR=\int (-0.5x+400) dx[/tex]
[tex]TR=-0.5\int x dx+400\int 1 dx[/tex]
[tex]TR=-0.5\times \dfrac{x^2}{2}+400x[/tex]
Now, substitute x=30 in the equation of Total Revenue (TR).
[tex]TR=-0.5\times \dfrac{30^2}{2}+400(30)[/tex]
[tex]TR=-0.5\times \dfrac{900}{2}+12000[/tex]
[tex]TR=-225+12000[/tex]
[tex]TR=11775[/tex]
Therefore, the total revenue from the production and sale of 30 units is $11,775.

Option (B) is correct.
What is the definition of photosynthesis?
What is photosynthesis ?Photosynthesis is the process by which green plants, algae and some forms of bacteria use energy from sunlight to convert carbon dioxide and water into glucose.
Given that:
Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar. 5 - 8
So, the process in which light energy is converted to chemical energy in the form of sugars is correct.

Joseph’s lunch at a restaurant costs $13.00, without tax. He leaves the waiter a tip of 17% of the cost of the lunch, without tax. What is the total cost of the lunch, including the tip without tax? *
Answer:
17% of 13 is 2.21
13 + 2.21 = 15.21
Step-by-step explanation:
Joseph's lunch costs = $13 without taxes
He leaves tip for the waiter = 17% of cost of the lunch
= 17% of $13
= 13 ×
= ( 13 × 0.17)
= $2.21
Total cost of lunch + tip = 13 + 2.21
= $15.21

If the slope of line a is -4/3 and the slope of line b is 3/4 line a and line b are perpendicular
A: True
B: False
C: False most of the time
Answer:
hi! so for perpendicular it's negative reciprocal!
so is -4/3 and 3/4 negative reciprocals?
oh and remember reciprocals are flipped!
if you still don't get it let me know aha
Answer:
True
Step-by-step explanation:
e Whenever you need to find the slope of a line, it is always the reciprocal with the opposite sign. For example, if your slope was 5, your slope to make it perpendicular would be -1/5. If you had the slope of -8/5, the perpendicular sope would 5/8.
