Step-by-step explanation:
100 books, half of them are fiction. So 50 of them are fiction. There are 50 books remaining. 10% of them are animal books. What is 10% of 50?
Convert 10% to a decimal: .10
Multiply .10 by 50
.10×50=5
5 books are animal books.
The classroom library contains 5 animal books.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
The operator that performs the arithmetic operations is called arithmetic operators.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
Given that the classroom library has 100 books.
And half of the books are fiction.
There are 50 books remaining and a tenth is about animals
So 10% of them are animal books.
To calculate 10% of 50 :
⇒ 10% of 50
⇒ 10%(50)
Convert 10% to a decimal,
⇒ 0.10×(50)
Multiply 0.10 by 50
⇒ 5
Hence, the classroom library contains 5 animal books.

9.6.6. The pawn shop business model. On April 9, 2011 The New York Times reported on a pawn shop that opened in an ex-Blockbuster store: The borrowers are given 60 days to pay back the loan, and La Familia charges a 20 percent interest rate per month. (So for a $100 loan, the borrower would need to pay back $140 after 60 days.) a. Explain why 20% interest per month on a $100 loan for two months would actually require repayment of a little more than $140. b. What is the annual interest rate when this business lends money?
Find the x- and y-intercepts for the linear equation.
– 3x + 5y = 15
Answer:
x-intercept: (-5,0)
y-intercept: (0,3)
Step-by-step explanation:
y-intercept: when x = 0
-3(0) + 5y = 15
5y = 15
y = 3
x-intercept: when y = 0
-3x + 5(0) = 15
-3x = 15
x = -5
Answer:
Step-by-step explanation:
To find the x-intercept of – 3x + 5y = 15, let y = 0 and solve the remaining equation for x: – 3x + 5(0) = 15
Then -3x = 15, and x = -5. Thus, the x-intercept is (-5, 0).
to find the y-intercept of – 3x + 5y = 15, set x = 0 and solve the remaining equation for y: 5y = 15, so that y = 3. The y-intercept is (0, 3).

point p lies on the directed line segment from A (2,3) to B (8,0) and portions the segment in the ratio 2 to 1
what’s the x coordinate of point p?
Answer:
The x-coordinate of point P is 6
Step-by-step explanation:
we have
A (2,3) and B (8,0)
we know that
Point P portions the segment AB in the ratio 2 to 1
so
[tex]AP=\frac{2}{3} AB[/tex]
and
[tex]AP_x=\frac{2}{3} AB_x[/tex]
where
AP_x represent the distance between the points A and P in the x-coordinates
AB_x represent the distance between the points A and B in the x-coordinates
[tex]AB_x=8-2=6\ units[/tex]
[tex]AP_x=\frac{2}{3} (6)=4\ units[/tex]
The x-coordinate of P is equal to
[tex]P_x=A_x+AP_x[/tex]
where
A_x represent the x-coordinate of A
substitute the values
[tex]P_x=2+4=6[/tex]
therefore
The x-coordinate of point P is 6

Doe the math equation y=6x -4 have a negative slope
Answer:
yes it does have a negative slope
Step-by-step explanation:
Final answer:
The equation y=6x - 4 does not have a negative slope; instead, it has a positive slope because the coefficient of x is positive, indicating that y increases as x increases.
Explanation:
The math equation given is y=6x - 4. To determine whether it has a negative slope or not, we look at the coefficient of x, which in this case is 6. A negative slope indicates that as x increases, y decreases, and vice versa. However, since the coefficient of x here is positive (6), this line has a positive slope, not a negative one. Therefore, it means that as x increases, y also increases, which is characteristic of a positive relationship between x and y.
It is important to note that a line with a negative slope would have a negative coefficient of x. The slope is the number that is multiplying the x variable, and it represents the rate of change of y with respect to x. Graphically, a line with a positive slope, such as this one, will rise as it moves from left to right on a graph.
Gwen borrows $300 from her parents to buy a bike. She agrees to pay them back plus 3% simple interest over one year. Write an equation to represent the total amount Gwen will owe her parents. What is the total amount of money Gwen will owe her parents?
Answer:
$309
Step-by-step explanation:
Use the formula for simple interest: [tex]A = P(1+rt)[/tex]
A represents total amount, unknown in this case.
P represents principal, or starting amount, 300 in this case.
r represents the interest rate in decimal form, 3% in this case, or 0.03.
t represents time, usually in years, 1 in this case.
[tex]A = P(1+rt)[/tex]
[tex]A = 300(1+(0.03)(1))[/tex]
[tex]A = 300(1.03)[/tex]
[tex]A = 309[/tex]

A triangle has two angles measuring 69 and 77. Determine the measure of the third angle b
Answer:
[tex]m\angle B=34\°[/tex]
Step-by-step explanation:
Given measures of 2 angles of a triangle :
m∠A = 69°
m∠C = 79°
Find m∠B.
We know that sum of angles of a triangle =180°
So, we have
[tex]m\angle A+m\angle B+m\angle C=180\°[/tex]
Substituting the vales of m∠A = 69° and m∠C = 79°
[tex]69\°+m\angle B+77\°=180\°[/tex]
Adding like terms.
[tex]m\angle B+146\°=180\°[/tex]
Subtracting both sides by 146°.
[tex]m\angle B+146\°-146\°=180\°-146\°[/tex]
∴ [tex]m\angle B=34\°[/tex] (Answer)

Jeanne is helping her dad with his
stueco business for the summer. Since Jeanne
has studied surface area in school, she does
some estimates for her dad's business,
For the garage at the right, they plan to stucco
the walls. They will not stucco the roof, car door,
side door, or window. The car door measures
5 m by 2.3 m, the side door measures 2.1 m by
0.9 m, and the window measures I m by 0.7 m.
Determine the surface area to be covered with stucco to the nearest square metre,
The surface area to be covered with stucco is 25.91 square metres.
Explanation:To find the surface area to be covered with stucco, we need to calculate the area of each wall and subtract the areas of the car door, side door, and window. The garage has four walls, so we will calculate the area of each wall and add them together. The area of each wall is the product of its length and height. Once we have the total area of the walls, we can subtract the areas of the car door, side door, and window to determine the final surface area to be covered with stucco.
Wall 1: 5 m * 2 m = 10 m²
Wall 2: 5 m * 2 m = 10 m²
Wall 3: 5 m * 2 m = 10 m²
Wall 4: 5 m * 2 m = 10 m²
Total area of walls: 10 m² + 10 m² + 10 m² + 10 m² = 40 m²
Area of car door: 5 m * 2.3 m = 11.5 m²
Area of side door: 2.1 m * 0.9 m = 1.89 m²
Area of window: 1 m * 0.7 m = 0.7 m²
Final surface area to be covered with stucco: 40 m² - 11.5 m² - 1.89 m² - 0.7 m² = <<25.91=25.91>>25.91 m² (rounded to the nearest square metre).

Learn more : https://brainly.com/question/13218948
Final answer:
Mindy saved $90 over 6 weeks, suggesting a constant rate of saving $15 per week. The proportional relationship between her total savings (y) and the number of weeks (x) is y = 15x.
Explanation:
Mindy started with $0 and after six weeks had $90. To find the proportional relationship between the money saved and the number of weeks, we assume that she saves the same amount every week. Since we know the total savings and the total time, we can divide the total savings by the number of weeks to find the constant rate.
Mindy's weekly saving rate would be:
Calculate the total amount saved: $90.
Divide the total amount by the number of weeks: $90 ÷ 6 weeks.
The result is $15 per week.
Therefore, the constant rate of saving is $15 per week. The proportional relationship can be represented as y = 15x, where y represents the total amount saved and x represents the number of weeks.

Answer:
Emma was right to say that both packages are close to 2 pounds.
If we round-off the weights of both to the nearest whole number we would get 2 pounds on both. We look at the the difference of both from 2 pounds we get the following:
2.36 - 2.0 = 0.36
2.09 - 2.0 = 0.09
The smaller the difference the closer it is to the base value. So we can say that the closest one is 2.0 pounds is the package that weighs 2.09 pounds.
