Aisha went shopping for a new pair of sneakers. The listed price of the pair of
sneakers was $43, but the price with tax came to $44.29. Find the percent sales tax.
The percent sales tax of the purchase is 3 %.
How to find percent sales tax?A sales tax is a consumption tax imposed by the government on the sale of goods and services.
She went shopping for a new pair of sneakers.
The listed price of the pair of sneakers was $43, but the price with tax came to $44.29.
Therefore, the percent sales tax can be found as follows:
sales tax = 44.29 - 43
sales tax = $1.29
Therefore,
percent sale tax = sale tax / cost with tax × 100
percent sale tax = 1.29 / 43 × 100
percent sale tax = 129 / 43
Therefore,
percent sale tax = 3%

Terry bought 2 shirts for $14 each, 2 pair of socks for $2.99 a pair, and a pair of slacksfor $25.00. The sales tax rate is 6.5%. How much did he pay? (Enter the dollar amountonly. Round to the nearest cent.)
Answer:
Explanation:
Terry bought 2 shirts for $14 each.
That is $28 on shirts
2 pair of socks for $2.99
That is $5.98 on socks
A pair of slacks for $25
The sales tax rate is 6.5% or 6.5/100 or 0.065
We want to know how much he paid.
Adding all the items he bought together, we have:
$28 + $5.98 + $25
= $58.98
Next, we apply the sales tax rate.
Take 6.5% of $58.98
This is: $58.98 * 0.065
= $3.83
Finally, add the sales tax with the amount we got
$58.98 + $3.83
= $62.81
He paid $62.81 in total
in the first week of July, a record 1,020 people went to the local swimming pool. In the second week, 100 fewer
people went to the pool than in the first week. In the third week, 135 more people went to the pool than in the second week.
In the fourth week, 137 fewer people went to the pool than in the third week. What is the percent decrease in the number of
people who went to the pool over these four weeks?
With the concepts of percentages and calculations, the percent decrease in the number of people who went to the pool over these four weeks is 10%
What is the way to solve percentages?Take the base as 100 and convert the percentage to numbers and then proceed with the same.
Now, the initial number of people in the local swimming pool is 1020, after which 100 fewer went, hence 920 people
Now, 135 people more people need to be added, thus 1055 people.
Now, 137 fewer people went, so 918 people went to the pool in the four weeks.
Therefore percent decrease = Difference/No. of people in the first week * 100
Thus, the percent decrease = 102/1020*100=10%
Hence 10% of people went less in the fourth week as compared to the first week.

Two straight lengths of wire are placed on the ground, forming vertical angles. If the measure of one of the angles formed is 72degrees, what are the measures of the other three angles? Explain your answer. (15 points and brainliest)
72, 108, and 108 are the other three angles formed by the two straight lengths of wire.
What is termed as the vertical angles?When two lines intersect, the two angles that really are opposite each other are referred to as vertical angles. Vertical angles are so named not because they are oriented vertically, but because they share a same vertex, this same point of intersection between the two lines.For the given question.
Two straight lengths of wire are put on the ground, to form vertical angles.
Because vertical angles have always been congruent, 72 is the vertical angle to 72.
Because the line is straight, the answer is 180.
180 - 73 equal 108. (supplement angles)
Because they are both vertical angles, there are two 180s.
Thus, the three angles formed are 72, 180 and 180 degrees.

8
square feet. What was the width of the plywood?
The width of the plywood = 23/8 ft
The two rectangular pieces of plywood had equal widths.
The length of first rectangular piece = 6 ft
The length of second rectangular piece = 5 1/2 ft = 11/2 ft
The two pieces are joined to make a single rectangular stage.
Then the total length of the stage = 6 + 11/2 = 23/2 ft
Now area of the rectangular stage = 66 1/8 = 529/8 square feet.
⇒ length x width = 529/8
⇒ 23/2 x width = 529/8
⇒ width = 529/8 x 2/23 = 23/4 ft
Let 'x' be the width of a rectangular plywood.
Then 2x = width of the stage
⇒ 2x = 23/4
⇒ x = 23/8 ft
Hence width of the plywood = 23/8 ft

Find WI if IE = 3
EW and YG are medians of XYW
Based on the definition of the median and applying the centroid theorem, the length of WI is calculated as: 6 units.
What is the Median of a Triangle?The line that joins the vertex of a triangle to the midpoint of the side it is directly opposite is called the median of a triangle.
Medians intersect each other at a point inside the triangle that is called the centroid. Based on the centroid theorem, since J is the centroid of triangle XYW, then:
the length of IE is one-third of the length of segment EW (referring to the image given in the question that shows triangle XYW)
Thus, we have the equation that relates the length of the segments as shown below:
IE = 1/3(EW)
Given that:
IE = 3 units
Substitute the value of IE into the equation:
3 = 1/3(EW)
3(3) = EW
9 = EW
EW = 9 units
Therefore:
Length of WI = the length of EW - the length of IE
Substitute
Length of WI = 9 - 3
Length of WI = 6 units.

Examine graphs A and B. What do you notice about the difference between the Y axis for the good graph A and the Poot graph B? How is a break shown on the Y axis of graph A
Answer:
The well-desgined graph has an appropriate scale for the y-axis. By appropriate we mean that the scale is such that all points on the graph can be discerned easily. In other words, the scale is not too wide or too narrow.
For graph A, the scale is such that the data points are at such a distance from each other that their values can be easily read off. On the other hand, for graph B, there isn't enough vertical distance between the data points for them to be easily read.

b. What is the probability of getting a factor of 6?
The probability of getting an even number is 1/2 while the probability of getting a factor of 6 is 1/6
How to determine the probabilities?The probability of an even number
From the question, the sample space of the number cube is given as
Space = 1, 2, 3, 4, 5, and 6
The above means that
Sample size, n = 6 ---- i.e. the number of observations
Number of even numbers, x = 3
The probability of getting an even number is then calculated as
P(Even) = Number of even numbers/Sample size
This gives
P(Even) = 3/6 = 1/2
The probability of a factor of 6
From the question, the sample space of the number cube is given as
Space = 1, 2, 3, 4, 5, and 6
The above means that

Mia made a mistake in Step 3. She simplified the exponents 16 and -8 incorrectly. She should have subtracted them.
Which properties of exponents are used in this problem?When two terms with the same base and different exponents are multiplied, we keep the base and add the exponents, as follows:
3^0 x 3^(16) = 3^(0 + 16) = 3^16.
Hence the Step 1 is correct.
For the power of power rule, we keep the base and multiply the exponents, hence:
(3^(-4))² = 3^(-4 x 2) = 3^(-8).
Hence the Step 2 is correct.
When two terms with the same base and different exponents are divided, we keep the base and subtract the exponents, as follows:
3^16/(3^(-8)) = 3^(16 - (-8)) = 3^(16 + 8) = 24.
Which is Mia's mistake, as she did not subtract the exponents.

This is 65.5% of the distance from Noor’s house to her grandparents’ house. What is the distance between the two houses? Round your answer to the nearest tenth of a mile.
The distance between Noor's house and her grandparent's house is 37.40 miles or if rounded off to the nearest tenth, it will be 40 miles using the estimation concept.
As per the question statement, Noor’s family is meeting her grandparents at a restaurant and the restaurant is 24.5 miles from Noor’s house but this is 65.5% of the distance from Noor’s house to her grandparents’ house.
We are supposed to find the distance between Noor's house and her grandparent's house. We will use the concept of estimation.
Distance between Noor's house and restaurant = 24.5 miles
Let distance between Noor's house and her grandparent's house be "x" miles.
So the distance between grandparent's house and restaurant = x - 24.5
Now it is given that 24.5 miles is 65.5% of the distance from Noor’s house to her grandparents’ house.
So, 65.5% of x = 24.5
(65.5*x)/100 = 24.5
65.5*x = 2450
x = 2450 / 65.5
x = 37.40 miles
If rounded off to the nearest tenth mile, we get
x = 40 miles.
So, the distance between Noor's house and her grandparent's house is 37.40 miles or if rounded off to the nearest tenth, it will be 40 miles.
