Write the fraction as a percent. Round to the nearest tenth of a percent if necessary.21/20A) 200%B) 10.5%C) 105%D) 52.5%
Answers
Given the fraction:
\(\frac{21}{20}\)You can identify that the numerator is 21 and the denominator is 20.
In order to write the fraction as a percent, you need to:
1. Divide the numerator by the denominator:
\(21\div20=1.05\)2. Multiply the Quotient obtained by 100 (this is the same as moving the decimal point two places to the right):
\(1.05\cdot100=105\text{\%}\)Hence, the answer is: Option C.

When solving a problem that uses the completing the square method, after you complete the square, what would the perfect square trinomial be for the problem:
2x^2+12x=32
options::
A) (x+3)^2 = 25
B) (x+3)^2 = 41
C) (x+6)^2 = 68
D) (x+6)^2 = 25
Answers
Answer: A
Step-by-step explanation:
First, let's rewrite the given equation to have the constant term on the right side:
2x^2 + 12x = 32
2x^2 + 12x - 32 = 0
To use the completing the square method, we need to make the coefficient of the x^2 term equal to 1. We can do this by dividing the entire equation by 2:
x^2 + 6x - 16 = 0
Now, we will complete the square for the quadratic expression on the left side. To do this, we take half of the coefficient of the x term (6/2 = 3) and square it (3^2 = 9). Then, we add and subtract this value inside the parenthesis:
x^2 + 6x + 9 - 9 - 16 = 0
Now, the left side of the equation has a perfect square trinomial:
(x^2 + 6x + 9) - 25 = 0
The trinomial can be written as a square of a binomial:
(x + 3)^2 - 25 = 0
Now, let's move the constant term to the right side of the equation:
(x + 3)^2 = 25
The perfect square trinomial for the problem is (x + 3)^2 = 25
The number of children's books at a library was 2/5 of the total number of books. After 298 children's books were added to the library, the number of children's books was 4/7 of the total number of books. How many books were there in the library at first?
Answers
Answer:
745
Step-by-step explanation:
You want the original number of books in the library if adding 298 children's books increased the fraction of children's books from 2/5 to 4/7.
RatioWe often like to work problems like this in terms of "ratio units." Here, we'll let x represent the number of books in a ratio unit. This means the number of children's books is originally 2x, and the total number of books is originally 5x. Then we have ...
(2x +298)/(5x +298) = 4//7
SolutionCross multiplying gives ...
7(2x +298) = 4(5x +298)
3(298) = 6x . . . . . . . . . . . . . subtract (14x+4(298))
149 = x
745 = 5x . . . . . . the original number of books in the library
There were 745 books in the library at first.
__
Additional comment
If we let x represent the original number of library books, then the arithmetic involves more fractions. You would have an equation like ...
2/5x +298 = 4/7(x +298)

A system of equations is given.

Equation 2: 9x + 2y = 7
Explain how to eliminate x in the system of equations.
Answers
Step-by-step explanation:
To eliminate x in the system of equations:
1. Multiply Equation 1 by 9 and multiply Equation 2 by -4, this gives:
Equation 1: 36x -54y = 90
Equation 2: -36x - 8y = -28
2. Add the two equations together to eliminate x:
(36x - 54y) + (-36x - 8y) = 90 - 28
Simplifying, we get:
-62y = 62
3. Solve for y:
y = -1
4. Substitute y = -1 into one of the original equations, say Equation 1:
4x - 6(-1) = 10
Simplifying, we get:
4x + 6 = 10
5. Solve for x:
4x = 4
x = 1
Therefore, the solution to the system of equations is x = 1 and y = -1. We can check that these values are correct by substituting them back into the original equations and verifying that they satisfy both equations.

Patrick's gross earnings for the week are $1592.45. His deductions comprise 26% of his total compensation. What is his net pay? Enter your answer rounded to the nearest cent, such as: $4253.64.
Answers
Patrick's net income will be equal to $1178.41.
What is the percentage?The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that Patrick's gross earnings for the week are $1592.45. His deductions comprise 26% of his total compensation.
Patrick's net income will be calculated as below:-
26% of $1592.45 = 1592.45 x ( 26 / 100 ) = 414.037
Subtract the deduction from the gross amount:-
Net income = 1592.45 - 414.037 = $1178.41
Therefore, Patrick's net income will be equal to $1178.41.

Which is a better deal, 5 tickets for $12.50 or 8 tickets for $20.16? Explain your reasoning
Answers
Answer:
5 for 12.50
Step-by-step explanation:
i think this is better because when you find the cost per ticket on this deal (divide 12.5 by 5), you get 2.5 dollars per ticket. the other deal was 8 for 20.16. when dividing 20.16 by 8, you get 2.52 per ticket.
overall, you end up paying less because 12.50 is obviously less than 20.16 and also the cost per ticket is just a little lower, 2.5 instead of 2.52.

To find the area of a rectangle, you need to multiply its length by its width. The formula for the area of a rectangle is:
Area = Length x Width
To find the area of the six-sided composite figure, lets divide it into two smaller shapes: a rectangle and a triangle.
The rectangle has a length of 10 meters and a width of 18 meters, so its area is:
10 meters × 18 meters = 180 square meters
The triangle has a base of 18 meters and a height of 2 meters, so its area is:
(1/2) × 18 meters × 2 meters = 18 square meters
The total area of the six-sided composite figure is the sum of the areas of the rectangle and the triangle:
180 square meters + 18 square meters = 198 square meters
Therefore, the total area of the figure is 198 m².
