A bicycle has a listed price of $521.99 before tax. If the sales tax rate is 7.5%, find the total cost of the bicycle with sales tax included.Round your answer to the nearest cent, as necessary.
Total cost of the bicycle with sales tax included = $561.14
STEP - BY - STEP EXPLANATION
What to find?
The total cost of the bicycle with sales tax included.
Given:
Price of bicycle before tax = $521.99
Tax rate = 7.5%
To solve the given problrm, we will follow the steps below:
Step 1
Calculate the amount of the tax rate.
[tex]\text{amount of tax rate =}\frac{7.5}{100}\times521.99[/tex][tex]=\frac{3914.925}{100}[/tex][tex]=39.14925[/tex]Step 2
Add the amount of tax obtained in step 1 to the price of bicycle before tax.
[tex]\text{Total tax =price of bicycle before tax+tax}[/tex][tex]=521.99+39.14925[/tex][tex]\approx561.14[/tex]Therefore, the total cost of the bicycle with sales tax included is $561.14

Determine the angle measures of quadrilateral EFGH that would result in it's similarity to quadrilateral ABCD
Solution:
If two angles of a triangle have measures equal to the measures of two angles of another triangle, then the triangles are similar. Corresponding sides of similar polygons are in proportion, and corresponding angles of similar polygons have the same measure. Two congruent shapes are similar, with a scale factor of 1.
Similarity statement:
In geometry, it states that two sides are similar if they have the same side ratio and the same angles
From the image in the question,
The quadrilateral ABCD has the following angles
[tex]\begin{gathered} m\angle A=90^0 \\ m\angle B=132^0 \\ m\angle C=73^0 \\ m\angle D=65^0 \end{gathered}[/tex]From the similarity statement above,we can deduce that
[tex]undefined[/tex]The daily dose for a man who weighs 175 pound is
Daily dosage of medicine for every 20 pounds of body weight = 70 mg
Daily dosage of medicine for every 1 pound of body weight = 70/20 mg
Daily dosage of medicine for every 1 pound of body weight = 3.5 mg
Daily dosage of medicine for every 175 pounds of body weight = 175 x 3.5
Daily dosage of medicine for every 175 pounds of body weight = 612.5 mg
Therefore, the daily dose for a man who weighs 175 pounds is 612.5 mg
If the man is to receive 900 mg in 8 hours
Dosage he will receive in 1 hour = 900/8
Dosage he will receivw in 1 hour = 112.5 mg
Dosage he will receive in 24 hours = 112.5 x 24
Dosage he will receive in 24 hours = 2700 mg
This means the man will take 2700 mg instead of the normal 612.5 mg. He is receiving the wrong dosage

Model Kara’s plan with a table,graph, and a explicit and recursive equation
We will write functions for the money that Kara and Kevin will receive each day.
1) The first day, Kara receives $3, and then she receives $1 more each day.
The money that she receives the n day is given by the following recursive function
[tex]f(n)=f(n-1)+1[/tex]where n is the nth day, and f(1) = 3. We can also write this function in the following form:
[tex]f(n)=3+(n-1)\cdot1[/tex]2) In the case of Kevin, he receives $0.25 the first day, and the next day he will receive the double.
So we can write the following recursive function:
[tex]g(n)=2\cdot g(n-1)[/tex]where n is the nth day, and g(0) = 0.25/2. We can also write this function in the following form:

Mr. Nguyen bought a suit that was on sale for 40% off the original price. He paid 9% salea tax on the sake price. The original price of the suit was $260. How much did he pay for the suit, including tax, to the nearest dollar?
The original price of the suit was $260. If the sale price was 40% off the original price, it means that the amount of discount was
40/100 * 260 = 104
The sale price is 260 - 104 = $156
If he paid sales tax of 9% of the sale price, it means that the amount of tax is
9/100 * 156 = 14.04
Therefore, the amount that he paid including tax is
156 + 14.04 = $170.04
Rounding up to the nearest dollar, the amount is $170

Two girls 21 miles apart. One going 3.5 mph one going 2.5 mph. How long until they meet up?
From the picture,
x + y = 21
From definition,
speed = distance/time
The girl whose speed is 3.5 mph, walks x miles in t hours, that is:
3.5 = x/t
or
x = 3.5t
Similarly,
y = 2.5t
(they walk for the same time)
Replacing into the first equation:
3.5t + 2.5t = 21
6t = 21
t = 21/6
t = 3.5
It will take 3.5 hours until they meet up

ma ate one slice of pizza, pa ate 2 pizza slices how much pizza did they eat together, what percent of the pizza is not eaten?
According to the given data we have the following:
ma ate one slice of pizza
pa ate 2 pizza slices
Therefore, if there are 8 slices of pizza, the amount of pizza thay they ate together would be calculated as follows:
amount of pizza thay they ate together= number of pieces that they ate together/The total number of pieces
amount of pizza thay they ate together=3/8
amount of pizza thay they ate together=0.375
Therefore to calculate the amount of pizza that is not eaten we would have to make the following calculation:
amount of pizza that is not eaten=1-0.375
amount of pizza that is not eaten=0.625
Therefore, the percent of the pizza is not eaten is 62.5%

In general, the formula to find the midpoint of a line segment which ends have the coordinates (x₁,y₁) and (x₂,y₂) is given by
[tex]M=(\frac{x_2+x_1}{2},\frac{y_2+y_1}{2})[/tex]Working with the formula we are given, for the x coordinate of the midpoint we have:
[tex]x=(\frac{a}{a+b})(x_2-x_1)+x_1=\frac{a(x_2-x_1)}{a+b}+\frac{(a+b)x_1}{a+b}[/tex]In order for this to be like the previous formula, we have the following equation:
[tex]\frac{a(x_2-x_1)}{a+b}+\frac{(a+b)x_1}{a+b}=\frac{x_2+x_1}{2}[/tex]From here, we see that a+b must be equal to 2, so:
[tex]\frac{a(x_2-x_1)}{2}+\frac{2x_1_{}}{2}=\frac{ax_2-ax_1}{2}+\frac{2x_1}{2}=\frac{ax_2-ax_1+2x_1}{2}=\frac{x_2+x_1}{2}[/tex]In order for this last equation to be true, a must equal 1:
[tex]\frac{x_2-x_1+2x_1}{2}=\frac{x_2+x_1}{2}[/tex]Let's verify this with the formula for the y coordinate of the midpoint:
[tex](\frac{1}{2})(y_2-y_1)+y_1=\frac{y_2-y_1}{2}+y_1=\frac{y_2-y_1}{2}+\frac{2y_1}{2}=\frac{y_2-y_1+2y_1}{2}=\frac{y_2+y_1}{2}[/tex]Since using our previous deduction leads us to the correct formula for the y coordinate of the midpoint as well, we can conclude that a=1 and a+b=2.
