You are applying for a fuel tax rebate. The amount of fuel road tax is 32 cents per gallon. If the refund is 50 % of this amount, what is the refund for 8,000 gallons of fuel?
Answer: $1,280
Step-by-step explanation:
The refund one a gallon is 50% of the cost of the gallon which is $0.32.
The refund on a gallon is:
= 50% * 0.32
= $0.16
If it was for 8,000 gallons the refund would be:
= 8,000 * 0.16
= $1,280

Find the exact value of [[23]]
Answer:
16 is your Correct answer. Thanks.
A business traveler was wondering how the taxi meters in a particular city work. She kept track of the distance traveled on each of her taxi rides and the amount
she paid for each of her fares. She then plotted the data points and found that while they didn't exactly form a line (probably due to varying times spent stuck in
traffic), they could be approximated by the line y = 1.75x+2.25, where x is the distance traveled in miles and y is the fare in dollars. According to the model, about
how much will a 3 mile ride cost?
A. $5.25
B. $6.75
С. $7.50
D. $8.50

A ball is thrown into the air with an initial upward velocity of 48 ft/s. It height h in feet after t seconds is given by the function h (t)=-16t^2+48t+4.
In how many seconds will the ball reach its maximum height?
Answer:
Step-by-step explanation:
h(t)=-16t^2+48t+4
dh/dt=-32t+48
d2h/dt2=-32
Since acceleration is always negative when the velocity, dh/dt=0, it will occur at the maximum height.
dh/dt=0 when
-32t+48=0
-32t=-48
t=1.5 seconds
Without calculus, the vertex of a parabola will be at -b/(2a) of the quadratic equation. In this case
-48/(2(-16))
-48/-32
1.5 seconds

Write an equation in slope intercept form of (-6,5),(6,-1)
Answer:
y=-1/2x+2
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-1-5)/(6-(-6))
m=-6/(6+6)
m=-6/12
m=-1/2
y-y1=m(x-x1)
y-5=-1/2(x-(-6))
y-5=-1/2(x+6)
y=-1/2x-6/2+5
y=-1/2x-3+5
y=-1/2x+2

18.5 ft, 6 ft, 17.5 ft
Answer:
yes, it is a right triangle.
Step-by-step explanation:
you could use the pythagorean theory to check:
[tex]a^{2} + b^{2} = c^{2}[/tex]
(the hypotenuse is the longest side)
[tex]17.5^{2} + 6^{2} = 18.5^{2}[/tex]
[tex]306.25 + 36 = 342.25[/tex]
[tex]342.25 = 342.25[/tex]

6. The number of bacteria N in a culture is given by the model N(t) = 250e 0.0156 where t is the time in hours.
Find how many hours it takes for the original population to double. Round your answer to the nearest hundredth
of an hour.
i just need to know how to work this out!! please help
Answer:
t ≈ 44.43 hours
Step-by-step explanation:
Expression that models the population of a bacteria after time 't' is,
N(t) = [tex]250(e^{0.0156t})[/tex]
Here initial population = 250
And N(t) = Population after 't' hours
t = duration
We have to find the duration in which bacterial population gets doubled.
N(t) = 2×250 = 500
From the given expression,
500 = [tex]250(e^{0.0156t})[/tex]
[tex]e^{0.0156t}=2[/tex]
[tex]\text{ln}(e^{0.0156t})=\text{ln}(2)[/tex]
0.0156t[ln(e)] = 0.693147
0.0156t = 0.693147
t = [tex]\frac{0.693147}{0.0156}[/tex]
t = 44.432
t ≈ 44.43 hours
Pls help with finding slope and y intercept from 2 points‼️‼️❗️❗️❗️❗️
step 1: plot your points.
step 2: find the rise over run
step 3: place the rise over run in decimal form. say its 5 to the side and 2 up 2/5 (if it was a negative rise such as 2 down it would be -2/5)
step 4= find where it crosses the y line such ex: 0,8 it would be 8 (if it were negative it would be 0,-8: -8)
then put in y intercept form: y=2/5x+8
Design An art class is making a mural for their school which has a triangle drawn in the middle. The
length of the bottom of the triangle is x. Another side is 13 more than two times the length of the
bottom of the triangle. The last side is 10 more than the bottom of the triangle. Write and simplify an
expression for the perimeter of the triangle.
What is the expression for the perimeter of the triangle?
Answer: [tex]4x+23[/tex]
Step-by-step explanation:
Given
The length of the bottom of the triangle is x
Another side is [tex]2x+13[/tex]
The last side is [tex]x+10[/tex]
Perimeter is the sum of the side of triangles
[tex]\Rightarrow \text{Perimeter}=x+2x+13+x+10\\\Rightarrow \text{Perimeter}=4x+23[/tex]
Find the distance between each pair of points. simply the radicals no decimals (-12, 3) (-3, 15)
Answer:
15
Step-by-step explanation:
distance formula = square root of difference of y-values subtracted by difference of x-values
d = [tex]\sqrt{144+81}[/tex] = 15
Answer:
Step-by-step explanation:
d^2=dx^2+dy^2
d^2=(-3+12)^2+(15-3)^2
d^2=81+144
d^2=225
d=15
I got this find the perimeter of the rectangle length= 2x width= 10 + x i dont understand, can someone explain???
Answer:
6x + 20
Step-by-step explanation:
the formula for the perimeter of the rectangle is 2 x (length + width)
from the question length = 2x
width = 10 + x
2(2x + 10 + x)
2 (3x + 10 )
6x + 20

The sum of 3 consecutive even numbers is 78.
Answer:
25, 26, 27
Step-by-step explanation:
set up an equation so 3 consecutive numbers are n, n+1, and n+2
So n + n +1 + n + 2 = 78, so 3n + 3 = 78, 3n = 75, so n = 25
so the numbers are 25, 26, 27
