13. Suppose you live in a state that collects 18.2c excise tax on a gallonof gasoline. If you buy 18.5 gallons of gasoline, how much state excise taxis collected?a, $3.06b 83.37$2.99C
Answers
The excise tax on 1 gallon of gasoline = 18.2 cents
You will buy 18.5 gallons
We need to find the excise tax you should pay
At first let us change the cent to dollar
1 cent = 1/100 dollars
18.2 cents = 18.2 * 1/100 = 0.182 dollars
Now you will buy 18.5 gallons
You will pay = 18.5 * 0.182 = 3.367 Dollars
The state excise tax = $3.367
Round the number to the nearest cent, then it will be $3.37

Answers
Given that the total length of the ribbon on the roll is 5 yards.
Janet cuts 1 (1/3) yards of ribbon from the roll, then the remaining length of ribbon on the roll is calculated as,
[tex]\begin{gathered} \text{Remaining Ribbon length=Total Length-Length cut out} \\ \text{Remaining Ribbon length=}5\text{ yards-1}\frac{1}{3}\text{ yards} \\ \text{Remaining Ribbon length=}(5-\frac{4}{3})\text{ yards} \\ \text{Remaining Ribbon length=(}\frac{15-4}{3})\text{ yards} \\ \text{Remaining Ribbon length=(}\frac{11}{3})\text{ yards} \\ \text{Remaining Ribbon length=3}\frac{2}{3}\text{ yards} \end{gathered}[/tex]Thus, the length of the ribbon left on the roll is 3 (2/3) yards.

What is the equation of a line that passes through (1,4) and (3, -6)?l
Answers
The equation of the line is that passes through (1,4) and (3, -6) is
y = -5x + 9
First, write the equation in slope-intercept form:
y = mx + b
(the m is the slope, and b is the y-intercept)
Now, Lets find the slope(m) of the line by using the formula:
y2-y1/x2-x1
(-6 - 4)/ (3 - 1) = -10/2 = -5
Next, find the y-intercept (b) by using the slope-intercept form equation and substituting -5 in for m and one of the ordered pairs in for x and y:
4 = (-5)(1) + b
b = 9
-OR-
-6 = (-5)(3) + b
b = -6 + 15 = 9
b = 9
Now, we can write the full equation of the line:
y = -5x + 9 is the answer

A travel agency charges $64 for each bus ticket and $82 for each train ticket. How much does it cost for 3 bus tickets and 4 train tickets?
Answers
Cost of 3 bus tickets is $ 192 and cost of 4 train tickets is $ 328.
Explain the use of multiplication?
The process of finding the sum of two or more numbers is known as multiplication. The fundamental concept of repeatedly adding the same number is represented by the process of multiplication. We can rapidly determine the total number of things by multiplying.
When multiplying, we'll consider the number of groups with similar sizes and the number of items in each group.
It is given ,
Cost of each bus ticket = $ 64
Cost of each train ticket = $ 82
Number of bus ticket = 3
Number of train ticket = 4
Total cost of bus ticket = 3 × 64 = $ 192
Total cost of train ticket = 4 × 82 = $ 328
Hence , cost of 3 bus tickets is $ 192 and cost of 4 train tickets is $ 328.

Answer: D. 80 miles
Step-by-step explanation:
if 1 inch is 20 miles, then 4 inches is 4 x 20 = 80 miles what is real distance between City A and City B
1 inch = 20 miles4 inch = 4 x 1 inch = 4 x 20 miles = 80 milesAnswer:
D. 80 miles
Step-by-step explanation:
If the map distance between Cities A and B is 4 in, and the map scale is 1 in = 20 mi, then the actual distance between Cities A and B is:
[tex]\frac{4\text{ in}}{1}\times\frac{20\text{ mi}}{1\text{ in}}=\frac{80\text{ mi}}{1}=80\text{ mi}[/tex]
In other words, every one inch on the map equates to 20 miles in actual distance. Therefore, 4 inches equates to 80 miles.

3. the mean lifetime for cardiac stents is 8.7 years. a medical device company has implemented some improvements in the manufacturing process and hypothesizes that the lifetime is now longer. a study of 100 new devices reveals a mean lifetime of 9.3 years with a standard deviation of 3.8 years. is there statistical evidence of a prolonged lifetime of the stents?
Answers
There is no statistical evidence of a prolonged lifetime of the stents.
Given data,
n (sample size) = 100
X (sample mean) = 9.3
s (sample standard deviation) = 3.8
Next, we need to define the null hypothesis and alternative hypothesis
Null hypothesis
[tex]H_{o}[/tex] : u (mu) = 8.7
Alternative hyptohesis
[tex]H_{o}[/tex] : u (mu) > 8.7
Next, we need to do hypothesis testing to get the claim about a population mean is tested under the null and the alternative hypotheses by using t-test and p-value.
t-test is a sampling test statistic and used when the population standard deviation is unknown.
the t-test can be calculated as follows:
= [tex]\frac{X-u}{s/\sqrt{n} }[/tex]
= [tex]\frac{9.3-8.7}{3.8/\sqrt{100} }[/tex]
= 1.578
Next, we need to calculate the p-value using Microsoft excel function. The p-value helps decide whether to reject the null hypothesis.
Enter the function below in excel to calculate p-value:
=TDIST(1.578,40-1,1)
= 0.061322.
The p-values is greater than the common threshold ( p<0.05), which means We can conclude that there is no statistical evidence of a prolonged lifetime of the stents.

What is a translation transformation?A translation transformation is a rigid transformation in which the location of the image obtained from the pre-image is different, but the dimensions are the same.
11) The transformation is similar to a rigid transformation
The change in coordinate is from (2, 2), to (4, 1), which is a translation 2 units to the right and -1 unit down
12) The shape is preserved and the length of the sides are also preserved, therefore, the transformation is a rigid transformation, with a change from (5, 3) to (0, 5), which is a translation 5 units to the left and 2 units up.
13) The change in the coordinates from the pre-image to the image are from V(-3, 2) to V(-4, 5), which is a transformation of 1 unit to the left and 3 units up
14) The coordinates of a point on the pre-image is T(-5, 2), and the coordinates of the corresponding point on the image is T'(-5, 1), which is a translation of one unit downwards, [tex]T_{(0, \,-1)}[/tex]
15) A point on the pre-image is T(-3, -1), the corresponding point on the image is T'(0, 3), which indicates that the rule for the transformation is a translation of 3 units to the right and a vertical translation of 4 units upwards
16) The difference between the x and y values are;
Δx = 0 - 3 = -3
Δy = -3 - (-4) = 1
The transformation is therefore of the form [tex]T_{(-3, \,1)}[/tex], which is a translation of 3 units to the left and 1 unit upwards
17) The change in the x and y values are;
Δx = -2 - (-3) = 1
Δy = -3 - (-3) = 0
The rule of the transformation is therefore of the form [tex]T_{(1, \,0)}[/tex], which is a translation one unit to the right.
18) The change in the x and y values of the transformation are;
Δx = 1 - (-5) = 6
Δy = -4 - 1 = -5
The rule of the transformation is therefore, [tex]T_{(6, \,-5)}[/tex], which is a translation of 6 units to the right and 5 units down
19) The transformation of J(-5, 3), K(-3, 5), L(0, 1) to J'(-1, 3), K'(1, 5), L'($, 1) is a transformation of the form [tex]T_{(4, \,0)}[/tex] which is a horizontal translation 4 units to the right

length = 12 miles
width = 6 miles
Step-by-step explanation:
Framing algebraic expression and solving:length = x miles
width = (x - 6) miles
Area of rectangle = 72 square miles
length * width = 72
x * (x - 6) = 72
x*x - 6*x = 72
x² - 6x - 72 = 0
Sum = -6
Product = -72
Factors = 6 , (-12) { 6 + (-12) = -6 and 6*(-12) =-72 }
Rewrite the middle term using the factors.
x² + 6x - 12x - 72 = 0
x(x + 6) -12(x + 6) =0
(x + 6)(x - 12) = 0
{x + 6 = 0 is rejected as length will not have negative value}
x - 12 = 0

Equation of a straight line passing through a given pointFrom the question, we are to determine the equation of the line that passes through the given point and is parallel to the given equation.
The given point is (-4, -5)
The given equation is y = 1/2x - 4
NOTE: If two lines are parallel, then their slopes are equal
Now, we will determine the slope of the given line '
y = 1/2x - 4
Compare to the general form of an equation of a straight line
y = mx + b
Where m is the slope
and b is the y-intercept
Therefore, m = 1/2
That is, the slope of the line is 1/2
Now, we will determine the equation of the line that has a slope of 1/2 and that passes through the point (-4, -5)
Using the point-slope form of the equation of a straight line
y - y₁ = m(x - x₁)
Then,
y - (-5) = 1/2(x - (-4))
y + 5 = 1/2(x + 4)
y + 5 = 1/2x + 2
y = 1/2x + 2 - 5
