Mr. Newton wants to buy a shirt in Leavenworth Kansas that cost $20.The sales tax in Leavenworth is 8%. What would be the total price of the shirt after adding the sales tax?
First find the amount the price increased.
amount of change
= (percent change) x (starting value)
= (8%) x ($20)
= (0.08) x ($20)
= $1.60
(Remember to convert the percent to a decimal before multiplying.)
Now add the tax onto the price:
$20 + $1.60 = $21.60
The price, including sales tax, is $21.60.
volume of a square room is 256 cubic meter.
Area of 4 walls is 128 Sq.m
Find length and breath.
The length and breadth of the room is 4 meters
What is area of square?A square is a 2D figure in which all the sides are of equal measure. Since all the sides are equal, the area would be length times width, which is equal to side × side. Hence, the area of a square is side square.
A square has it's sides equal
A = l²
The area of 2 walls = 128/2 = 64
Therefore the length of each sides = √64
= 4meters
The height of the room = Volume/ height
= 256/128 = 2
The breadth of the room will also be 4meters

The percentile of a test score can be defined as the percent of test scores less than or equal to that test score
Use this definition to find the percentile of the test score 12
The test score 12 is at the ___th percentile
Answer:
Percentile = 90
Therefore, the test score 12 is at the 90th percentile.
Step-by-step explanation:
Percentile = (Number of scores less than or equal to score) / (Total number of scores) * 100
Percentile = (9) / (10) * 100

For two adjacent angles x° and (x + 30)° that make up a 90° angle, what is x
In the given situation, the required value of x for the given pair of adjacent angles is 30°.
What are adjacent angles?When two angles have a similar vertex and side, they are referred to as neighboring angles.
The vertex of an angle is the point at which the rays that make up its sides come to an end.
When adjacent angles have the same vertex and side, they can be a complimentary angle or supplemental angle.
The definition of adjacent is next to or nearby.
Two next-door residences are an illustration of proximity.
Typically, we think of those who live on our street as neighbors.
So, we have:
x + x + 30 = 90
Now, solve for x as follows:
x + x + 30 = 90
2x + 30 = 90
2x = 90 - 30
2x = 60
x = 60/2
x = 30
Therefore, in the given situation, the required value of x for the given pair of adjacent angles is 30°.

How to convert microgram to mg?
To convert micrograms (μg) to milligrams (mg), you can divide the number of micrograms by 1000. So, the formula for converting micrograms to milligrams is: mg = μg / 1000.
To convert micrograms to milligrams, divide the number of micrograms by 1000. This is because there are 1000 micrograms in 1 milligram. For example, if you have a measurement of 5000 micrograms and you want to convert it to milligrams, you would divide 5000 by 1000 to get 5 milligrams. This conversion is useful in many fields, including medicine, where medication dosages are often measured in milligrams, and scientific research, where precise measurements of small amounts of substances are necessary.
For example, let's say you have a measurement of 5000 micrograms and you want to convert it to milligrams:
mg = 5000 μg / 1000
mg = 5 mg
Therefore, 5000 micrograms is equal to 5 milligrams.

The fraction of crayons that are blue triangle is 1/5.
The ratio of blue rounds to non-blue crayons is
The fraction of footballs that are brown rubber footballs is 8/15 and here are 4 times as many rubber footballs as non-rubber footballs
What is Fraction?A fraction represents a part of a whole.
1. Let's say Alexa had a total of 5x crayons in the bag.
the number of blue crayons in the bag is 2x,
There is one triangle for every two round crayons,
(1/2) × 2x = x (By condition)
So, the fraction of crayons that are blue triangle is x / 5x = 1/5.
The number of blue round crayons is 2x.
The number of non-blue crayons is 5x - 2x = 3x,
The ratio of blue rounds to non-blue crayons is 2x / 3x = 2/3.
2.
4 out of 5 wall footballs are rubber, 4/5 of the footballs in the bag are rubber.
The fraction of rubber footballs that are brown is 2/3.
The fraction of footballs that are brown rubber footballs is (4/5) × (2/3) = 8/15.
The fraction of non-brown rubber footballs is (4/5) - (8/15) = 4/15.
The ratio of rubber footballs to non-rubber footballs is (4/5) / (1/5) = 4.
So there are 4 times as many rubber footballs as non-rubber footballs
Hence, the fraction of crayons that are blue triangle is 1/5.
The ratio of blue rounds to non-blue crayons is
The fraction of footballs that are brown rubber footballs is 8/15 and here are 4 times as many rubber footballs as non-rubber footballs

1 mile = 5,280 feet
45 miles per hour
46 miles per hour
47 miles per hour
48 miles per hour
48 miles per hour is the most accurate rate of speed Morris is traveling
What is Unit of measurement?A measurement unit is a standard quantity used to express a physical quantity.
Given that Aneesha's speed is 50 miles per hour.
We need to convert to feet per second.
By given 1 mile = 5,280 feet
50×5280=264000 feet
Now divide by 36000
264000/36000
73.33 feet/second is the Aneeshas speed.
Morris is traveling 3 feet per second less than Aneesha, so his speed is:
73.33 - 3 = 70.33 feet/second
70.33× 3600 = 253,188 feet/hour
253,188 ÷ 5280 = 48 miles/hour

(−1.5, 0.25)
(−0.5, 0.75)
(1.5, 0.25)
(−2.5, 1.5)
Answer:
To approximate the solution to the system of equations, we need to find the point where the two lines intersect. From the second equation, we know that y = (1/2)x + 1. Substituting this expression for y into the first equation gives:
3x + 2[(1/2)x + 1] = -4
Simplifying and solving for x, we get:
3x + x + 2 = -4
4x = -6
x = -1.5
Substituting this value of x back into the second equation gives:
y = (1/2)(-1.5) + 1 = 0.25
Therefore, the solution to the system of equations is approximately (-1.5, 0.25).
So the answer is (−1.5, 0.25).
what are the factor pairs needed to answer 3z^2 + 26z - 9
Answer:
daddy
Step-by-step explanation:
hey daddy
Answer:
Therefore, the factor pairs needed to answer 3z^2 + 26z - 9 are (-3, 9) and (3z - 1, z + 9).
Step-by-step explanation:
To factor the quadratic expression 3z^2 + 26z - 9, we need to find two numbers that multiply to give us 3 times -9 = -27, and add up to 26.
One way to do this is to list all the factor pairs of -27 and look for the pair that has a sum of 26:
-27 and 1
-9 and 3
-3 and 9
-1 and 27
We can see that the pair that adds up to 26 is -3 and 9. So we can use these numbers to write the quadratic expression as a product of two binomials:
3z^2 + 26z - 9 = (3z - 1)(z + 9)
Therefore, the factor pairs needed to answer 3z^2 + 26z - 9 are (-3, 9) and (3z - 1, z + 9).

The foundation of a building is in the shape of a rectangle, with a length of 20 meters (m) and a width of 18 m.
The distance from the top left corner of the foundation to the bottom right corner is 27 meters.
The distance between two points in space can be calculated using the Pythagorean theorem. In this case, we want to find the distance from the top left corner of the foundation to the bottom right corner.
To do this, we will use the length and width of the foundation, which are 20 meters and 18 meters respectively.
The Pythagorean theorem states that in a right triangle, the square of the distance (c) between the two points is equal to the sum of the squares of the other two sides (a and b). Mathematically, this can be represented as
=> c² = a² + b².
In our case, the two sides are the length (20m) and width (18m) of the foundation. To find the distance, we will first find the square of c by adding the squares of a and b. So,
=> c² = 20² + 18² = 400 + 324 = 724.
To find the distance, we will take the square root of c².
So,
c = √724 = 26.83
When we rounded to the nearest meter, c = 27m.

Find the difference. use your answer in the simplest terms, using the slash ( / ) as the fraction bar.
1/2 - 1/4
Answer:
1/4
Step-by-step explanation:
You cannot subtract (or add) a fraction with different denominators so first, you need to find a common denominator. You can do this by finding the least common multiple (LCM).
Here the denominators are 2 and 4 so the LCM is 4.
After you find the LCM you need to multiply the denominator by a number that equals the LCM. Then multiply the numerator by that same number.
So convert both 1/2 and 1/4
1/4 x 1/1 = 1/4
1/2 x 2/2 = 2/4
Now we can just subtract the numerator from each other.
2/4 - 1/4 = 1/4
We cannot simplify the difference any more so keep it the same.
