Answer: 18.5%
Step-by-step explanation: Last year, there were 56 boys and 135 girls on the honor roll, for a total of 191 students. This year, the number of boys on the honor roll increased by 25%, which means there are now 70 boys on the honor roll (56 * 1.25). The number of girls on the honor roll increased by 20%, which means there are now 162 girls on the honor roll (135 * 1.20).
The total number of students on the honor roll this year is therefore 70 + 162 = 232.
To find the percentage increase in the total number of students on the honor roll, we can use the formula:
percentage increase = (new value - old value) / old value * 100
Plugging in the numbers, we get:
percentage increase = (232 - 191) / 191 * 100 = 21.47%
Rounding to the nearest tenth, we get an increase of approximately 18.5%.
Hope this helps, and have a great day!

Answer:
1. c. 276ft
2.56ft
Step-by-step explanation:
1. I took the length and multiplied that by the width to get the area
2.
Answer:
1. C
2. D
Step-by-step explanation:
For question 1 you would multiply 23 by 12 because the area of a rectangle is base * height. To get 276 which is C.
For question 2 you would find the area by doing 1/2(b*h) or 1/2(7*4) which equals 14. To find the area of 4 triangles you would then do 14*4 which equals 96.

Answer:
X=-6 and X=0
Step-by-step explanation:
I will solve this by factoring.
Factor x(x+6)=0 into to equations: X=0 and x+6=0.
Move the 6 to the other side which will make it negative and their is nothing to do with x=0.
So the final answer is X=-6 and X=0.
Answer:
x = 0 , x = -6
Step-by-step explanation:
Zero product propertyThe equation x(x+6) = 0 can be solved using the zero product property, which states that if the product of two factors is zero, then at least one of the factors must be zero.
So we can set each factor ( "x" and "x+6") equal to 0 and solve for x
Factor #1
x = 0
Factor #2
x + 6 = 0
==> subtract 6 from both sides
x = -6
Checking our workWe can now substitute the values of x into the original equation to check our work
x(x+6) = 0
==> plug in x = 0
0(0+6) = 0
==> simplify addition within parenthesis
0(6) = 0
==> multiply 6 and 0
0 = 0
x(x+6) = 0
==> plug in x = -6
-6(-6 + 6) = 0
==> add -6 and 6
-6(0) = 0
==> multiply -6 and 0
0 = 0
Both values of x satisfy the equation therefore the values of x are indeed -6 and 0

An equation that could be used to determine the number of books that Keiko bought include the following: B. 4b - 5 = 71.
The number of books is equal to 19 books.
How to write an equation to model this situation?In order to write a linear equation to describe this situation, we would assign a variable to the number of books, and then translate the word problem into a linear equation as follows:
Let the variable b represent the number of books.
Since Keiko bought some books for $4 and received a discount of $5 off of her total purchase, a linear equation that models the situation is given by this mathematical expression:
4b - 5 = 71
Next, we would calculate the number of books (b) as follows;
4b - 5 = 71
4b = 71 + 5
4b = 76
b = 76/4
b = 19 books.

Simplify each cube root expression. Describe the simplified form of the expression as rational or irrational. In your final answer, include all of your work.
3√81
3√-64
Answer:
Sure, I'd be happy to help you with these problems!
Simplifying square root expressions:
√121 = 11
The square root of 121 is a rational number because it can be expressed as a ratio of two integers (11/1).
√48 = √(16*3) = √16 * √3 = 4√3
The square root of 48 is an irrational number because it cannot be expressed as a ratio of two integers.
Simplifying cube root expressions:
3√81 = 3√(3^4) = 33 = 9
The cube root of 81 is a rational number because it can be expressed as a ratio of two integers (9/1).
3√(-64) = 3√(-444) = 34√(-4) = 12i√2
The cube root of -64 is an irrational number because it cannot be expressed as a ratio of two integers. However, it can be expressed as a product of a rational number (4) and an imaginary number (i√2), where i is the imaginary unit (i.e., i^2 = -1). Therefore, the simplified form of this expression is an imaginary number.
1. √121:
To simplify this expression, we need to find the square root of 121. The square root of 121 is 11, since 11 * 11 = 121. Therefore, the simplified form of √121 is 11.
Since 11 is a whole number, it is considered a rational number.
2. √48:
To simplify this expression, we need to find the square root of 48. We can simplify it by factoring 48 into its prime factors: 48 = 2 * 2 * 2 * 2 * 3.
Taking out pairs of identical prime factors, we get √48 = √(2 * 2 * 2 * 2 * 3) = 2 * 2 * √3 = 4√3.
The simplified form of √48 is 4√3.
Since 4√3 cannot be expressed as a fraction, it is considered an irrational number.
Now let's simplify each cube root expression and describe the simplified form as rational or irrational.
3. 3√81:
To simplify this expression, we need to find the cube root of 81. The cube root of 81 is 4, since 4 * 4 * 4 = 81. Therefore, the simplified form of 3√81 is 4.
Since 4 is a whole number, it is considered a rational number.
4. 3√-64:
To simplify this expression, we need to find the cube root of -64. The cube root of -64 is -4, since -4 * -4 * -4 = -64. Therefore, the simplified form of 3√-64 is -4.
Since -4 is a whole number, it is considered a rational number.
In summary:
- √121 simplifies to 11, which is a rational number.
- √48 simplifies to 4√3, which is an irrational number.
- 3√81 simplifies to 4, which is a rational number.
- 3√-64 simplifies to -4, which is a rational number.

As you know, the angles of a triangle must have a sum of 180 degrees.
Here you got the first part correct and for the second part all you need to do is write 76.2 as the angles they gave you equal 180 degrees.
76.2 + 81.7 + 22.1 = 180
