The ACT is a college entrance exam taken by high school students. The maximum score that can be earned is 36. The average score in the United States was 21.2 during a recent year. The average score for Vermont students that year was 7.5% higher than the national average. What was the average ACT score for Vermont students? Round your answer to the nearest tenth.
If the average score in the United States was 21.2 during a recent year. The average score for Vermont students that year was 7.5% higher than the national average. The average ACT score for Vermont students is: 22.80.
Average ACT scoreUsing this formula to determine the average ACT score
Average ACT score = Average score in the United states + ( Average score in the United States × Average score for Vermont students)
Let plug in the formula
Average ACT score = 21.2 + ( 21. 2 × 7.5%)
Average ACT score = 21.2 + 1.59
Average ACT score = 22.79
Average ACT score = 22.80 (Approximately)

The function h (x) = startfraction 1 over x squared 1 endfraction is the result of the composition f(g(x)). if g(x) = x2 1, what is f(x)? f (x) = startfraction 1 over startroot x endroot f (x) = startfraction 1 over x 1 endfraction f (x) = startfraction 1 over x squared 1 endfraction
This means that function of (x²+ 1) will give 1/(x²+ 1). To get f(x), we will simply replace x²+ 1 in the function f(x²+ 1) with x to give;
f(x) = 1/x
How do you define a function?
A technical definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given h(x) = 1/(x²+ 1) and g(x) = x²+ 1. If h(x) = f(g(x)) then;
1/(x²+ 1) = f(x²+ 1)
f(x²+ 1) = 1/(x²+ 1)
This means that function of (x²+ 1) will give 1/(x²+ 1). To get f(x), we will simply replace x²+ 1 in the function f(x²+ 1) with x to give output ;
f(x) = 1/x
Hence the function of x i.e f(x) is 1/x

One pound of grout is enough to grout a tiled area that is 110 sq. ft. Alyssa’s kitchen counter is made up of two rectangular segments. One is 10.3 ft by 2.5 ft, and the other is 3.1 ft by 2 ft. Which expression represents the number of pounds of grout Alyssa will need?
By taking the quotient between the area that one pound covers and the area of the kitchen, we conclude that Alyssa will need 0.29 pounds of grout.
How many pounds will Alyssa need?We know that one pound of grout covers a total of 110 square feet.
Alyssa's kitchen is made of two rectangular segments, one that measures 10.3ft by 2.5 ft, then the area of this rectangle is:
10.3ft*2.5ft = 25.75 ft²
The other rectangle has dimensions of 3.1ft by 2ft, so the area is:
3.1ft*2ft = 6.2ft²
The total area is:
25.75 ft² + 6.2ft² = 31.95 ft²
Now, with one pond of grout, they can cover 110 ft², then the number of pounds that Alyssa needs is:
N = 31.95 ft²/110 ft² = 0.29
Alyssa will need 0.29 pounds of grout.

She starts with $100 and plans to add $50 each week. write an equation she can use to calculate the amount of money she will have after any number of weeks. how much money will she have after 1 year?
Main Answer:
2700 dollars
Explanation:
Let x be the number of weeks and y be the total amount of money, then the equation can be written as,
[tex]y=50x+100[/tex] -------(1)
In a year there are 52 weeks.
Money she will have after 1 year is found out by putting x = 52 in the equation (1), we get
[tex]y=50(52)+100[/tex]
[tex]y=2600+100[/tex]
∴[tex]y=2700[/tex]
Therefore, the money she have after 1 year is 2700 dollars.
Use the slopes of lines A and B to show that
they are perpendicular
to each other.
The line A and line B are perpendicular to each other.
What is defined as the perpendicular lines?Perpendicular lines are defined in geometry as two lines which meet or intersect at right angles (90°). The term "perpendicular" is derived from the Latin phrase "perpendicularis," which means "a plumb line."The following are the two important properties of perpendicular lines.These lines are always at right angles when they intersect.If two lines seem to be perpendicular to each other, they are parallel and will never intersect.For the given ques, the graph of line A and line B are given.
The relation of slope of two perpendicular lines is their product of slope is -1.
Line A: select two point lying on the line A.
(2, 3) and (1, 1)
slope = m = (2 - 1)/(3 - 1)
m₁ = 1/2
Line B: select two point lying on the line B.
(8, 0) and (0, 4)
slope = m = (0 - 4)/(8 - 0)
m₂ = -4/8
m₂ = -1/2
Now, multiply both slopes.
m₁ x m₂ = 1/ 2 x -1/2
m₁ x m₂ = - 1

The perimeter of a pool is 116 feet. If the length of the pool is 3 times its width,
what is the width of the pool?
(Show work)
Answer:
The perimeter P of a rectangular is given by formula P=2l+2w where l is the length and w is width of rectangle.Given that perimeter is 56 meters and length's 16 meters. Substituting values in formula,subtract 32 from both sides -⇒24=2w w=12width of rectangular pool is 12 meters.Hence, the answer is 12.Answer:
Perimeter = 2(l+b)
Perimeter = 116
width = x
length = 3x
116 = 2(3x+ x)
116 = 6x+2x
116 = 8x
x = 116/8
x = 14.5
You can verify answer by inputing value of x to see if perimeter is = 116 :
perimeter = 2(l+b)
116 = 2(3(14.5) + 14.5)
116 = 2(43.5 + 14.5)
116 = 87 + 29

What is conversion of units?
The process of translating measurements of a given quantity between different units, frequently using multiplicative conversion factors that change the value of the measured quantity without changing its effects, is known as unit conversion. The specific circumstances and the desired result dictate the conversion process. This may be governed by a regulation, contract, set of technical requirements, or other publicly available standards.
What is the conversion factor for inch to mile?
A value in inch when divided by 63360 gives a value in mile.
What is the conversion factor for second to hour?
A value in second when divided by 3600 gives a value in hour.
Given, the speed of Caroline in inches per second = 9 1/2 = 9.5/1 - (i)
Therefore following above literature and dividing numerator by 63360 and denominator by 3600, we get the speed in miles per second.
Thus, required speed = [9.5/63360]/[1/3600) = 0.539 = 0.5
