In order to solve this exercise you need to remember the following:
[tex]1\text{ }hour=60\text{ }minutes[/tex]In this case, based on the information given in the exercise, a school day is 8 hours. Then, you need to make the conversion from hours to minutes.
You can set up the following:
[tex](8\text{ }hours)(\frac{60\text{ }minutes}{1\text{ }hour})[/tex]Therefore, evaluating you get:
[tex]=\frac{(60\text{ }minutes)(8\text{ }hours)}{1\text{ }hour}=480\text{ }minutes[/tex]Hence, the answer is:

BEST ANSWER PLS !!!
If there are 27 students in Mr. Mello's class then the total number of pages the students read by the end of November will be 1350.
Given that there are 27 students in Mr. Mello's class.
We are required to find the total number of pages that the students read by the end of November.
Assume that there are 50 pages in the book and all the pages are read in the month of November.
Total number of pages read by all the students by the end of November=27*50
(Product of number of pages in the book and the number of students)
= 1350 pages
Answer:
810

Answer : The linear function of the graph when move down 3 units is y = x - 3
The graph shift vertically because it is down 3 units
The standard equation of a linear function is
y = mx + b
Where b = intercept and m = slope
Move 3 unit down means b = -3
Hence, y = x-3
Answer is y = x - 3

Joshua is going to invest $9,000 and leave it in an account for 5 years. Assuming theinterest is compounded continuously, what interest rate, to the nearest tenth of apercent, would be required in order for Joshua to end up with $12,500?
Let r be the percent annual interest rate of the account. Since $9000 are left for 5 years, for an outcome of $12,500, then:
[tex]9000\times(1+\frac{r}{100})^5=12,500[/tex]Divide both sides by 9000:
[tex](1+\frac{r}{100})^5=\frac{12500}{9000}=\frac{25}{18}[/tex]Take the 5th root to both sides:
[tex]\begin{gathered} 1+\frac{r}{100}=\sqrt[5]{\frac{25}{18}} \\ \Rightarrow\frac{r}{100}=\sqrt[5]{\frac{25}{18}}-1 \\ \Rightarrow r=100(\sqrt[5]{\frac{25}{18}}-1) \end{gathered}[/tex]Use a calculator to find the decimal expression for r:
[tex]r=6.790716585\ldots[/tex]Therefore, to the nearest tenth:
[tex]r=6.8[/tex]This means that Joshua would need to invest his money on a 6.8% annual interest account.

Let E be the event where the sum of two rolled dice is less than 8. List the outcomes in Ec.
Explanations:
Answer:
what is the slope and y-intercept of negative 3x + 5y equals -15
-3x + 5y = -15
The general form of a line using slope and y intercept is: y = mx + b
where m is the slope and b is the y intercept
So we have to write the original equation in this form:
-3x + 5y = -15
5y = 3x - 15
y = (3/5)x - 15/5
y = (3/5)x - 3
In this case, m= 3/5 and b = -3
Therefore m = 3/5
Therefore the y intercept (when x = 0) is -3
Answer:
slope is 3/5
y intercept -3
Solve forx: 3x - 5 = 2x + 6.1-111-11
To solve the equation we need to isolate the "x" variable on the left side. This is done step-by-step below:
3x - 5 = 2x + 6
3x - 2x -5 = 6
x = 6 + 5
x = 11

There was a survey taken to see which types of pets people prefer. Out of 11 participents, 5 said they prefer dogs, 4 said they prefer cats, and 3 said they prefer birds. What is the percentages of people that prefer dogs, cats, and birds?
To find the percentages of people that prefer dogs, cats or birds, divide the corresponding amount of people that likes each pet by the total amount of people in the survey, and then multiply that quantity by 100.
Since there are 11 participants, we should divide each quantity by 11.

a basketball court is 94 ft long and 50 ft wide Ryan used long steps to estimate the length of the Court as 93 ft and a width as 48 what is the percent error of Ryan's measure area round to your nearest hundred
5.02%
Explanation:Percentage error formula = |(approximate value - Exact value)|/(exact value) × 100
Area of the court = length × width
length = 94 ft
width = 50 ft
Exact area = 94ft × 50 ft
Exact area = 4700 ft²
length = 93 ft
width = 48 ft
Approximate area = 93 ft × 48 ft
Approximate area = 4464 ft²
[tex]\begin{gathered} \text{percent error = }\frac{|4464\text{ - 4700|}}{4700}\times\text{ 100} \\ \text{percent error = }\frac{|-236|}{4700}\times100 \\ \text{percent error = }\frac{236}{4700}\times100 \end{gathered}[/tex][tex]\begin{gathered} \text{Percent error = }0.0502\text{ }\times\text{ 100} \\ \text{Percent error = 5.02\%} \end{gathered}[/tex]4) Select all ordered pairs that satisfy thefunction: y=-3x + 4A.(-2,10)B. (-1,1)C. (5,-11)D. (6,-22)
To know if an ordered pair satisfy an equation we have to substitute the values in it and see if the left side is equatl to the right side.
Pair (-2,10)
In this case x=-2 and y=10. Plugging the values in the equation:
[tex]\begin{gathered} 10=-3(-2)+4 \\ 10=6+4 \\ 10=10 \end{gathered}[/tex]since both sides have the same value, this paired satisfy the equation.
Pair (-1,1)
In this case x=-1 and y=1. Then
[tex]\begin{gathered} 1=-3(-1)+4 \\ 1=3+4 \\ 1=7 \end{gathered}[/tex]since this is not true, this ordered pair don't satisfy the equation.
Pair (5,-11)
In this case x=5 and y=-11. Then
[tex]\begin{gathered} -11=-3(5)+4 \\ -11=-15+4 \\ -11=-11 \end{gathered}[/tex]since this is true the ordered pair satisfy the equation.
Pair (6,-22)
In this case x=6 and y=-22. Then
[tex]\begin{gathered} -22=-3(6)+4 \\ -22=-18+4 \\ -22=-14 \end{gathered}[/tex]since this is not true, this ordered pair don't satisfy the equation.
Therefore the ordered pairs that satisfy the equation are the points A and C.

What is mean by Subtraction?
Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
The expression is,
⇒ (x² - 3x - 5) / (x² + 2x - 8) - (x² - 3x - 5) / (x² + 2x - 8)
Now,
Subtract the expression as;
The expression is,
⇒ (x² - x + 3) / (x² + 2x - 8) - (x² - 3x - 5) / (x² + 2x - 8)
⇒ (x² - x + 3) - (x² - 3x - 5) / (x² + 2x - 8)
⇒ x² - x + 3 - x² + 3x + 5 / (x² + 2x - 8)
⇒ 2x + 8 / (x² + (4-2)x - 8)
⇒ 2x + 8 / (x² + 4x - 2x - 8)
⇒ 2x + 8 / (x (x + 4) - 2 (x + 4))
⇒ 2(x + 4) / (x + 4) (x- 2)
⇒ 2 / (x - 2)
Thus, The value after subtraction will be;

3 Step Problem: Erik is building a cubby bookshelf, that is, a bookshelf divided into storage holes (cubbies) instead of shelves. He wants the height of the bookshelf to be x^2 - 2x - 3 and the width to be x^2 + 4x + 3. Each cubby hole in the bookshelf will have a height of x + 3 and width of x - 3.STEP 1 of 3: Write a rational expression to determine how many cubbies high the book shelf will be.
Step 1:
In order to determine the number of cubbies high, we just need to divide the total height x² - 2x - 3 by the height of one cubby x + 3:
x² divided by x: x
x multiplied by (x + 3): x² + 3x
x² - 2x - 3 minus x² + 3x: -5x - 3
-5x divided by x: -5
-5 multiplied by (x + 3): -5x - 15
-5x - 3 minus -5x - 15: 12
The division doesn't have remainder 0, so let's write the division as a fraction:
[tex]\text{number of cubbies}=\frac{x^2-2x-3}{x+3}[/tex]-2 5/7 x (-4 2/3). with steps
We want to do the following multiplication:
[tex](-2\frac{5}{7})\cdot(-4\frac{2}{3})[/tex]Let's transform that into a normal fraction:
[tex]\begin{gathered} 2\frac{5}{7}=2+\frac{5}{7}=\frac{14+5}{7}=\frac{19}{7} \\ \\ 2\frac{5}{7}=\frac{19}{7} \end{gathered}[/tex]and the other fraction
[tex]\begin{gathered} \text{ 4}\frac{2}{3}=4+\frac{2}{3}=\frac{12+2}{3}=\frac{14}{3} \\ \\ 4\frac{2}{3}=\frac{14}{3} \end{gathered}[/tex]Therefore we can multiply the following fractions:
[tex]\begin{gathered} (-\frac{19}{7})\cdot(-\frac{14}{3}) \\ \\ \end{gathered}[/tex]The result is
[tex](-\frac{19}{7})(-\frac{14}{3})=\frac{19}{7}\cdot\frac{14}{3}=\frac{19}{1}\cdot\frac{2}{3}=\frac{38}{3}[/tex]Therefore
[tex](-2\frac{5}{7})\cdot(-4\frac{2}{3})=\frac{38}{3}[/tex]if we want we can write it in the same form as the others

firstly you have to calculate the volume of the rectangular prism
volume = base area x height
since it is a rectangular prism
then the area = length x breath
length = 5cm , breath = 3cm
therefore
[tex]\begin{gathered} \text{Area = l }\times b \\ =\text{ 5 }\times3 \\ =15cm^2 \end{gathered}[/tex]volume = base area x height
volume = 15 x 2
[tex]\text{volume = 15}\times2=30cm^3[/tex][tex]^{}\text{thus, the cameron fills }\frac{1}{2}cm^3[/tex]so the amount of the cameron fills that can fill up the prism is

Well, this is a volume and ratio problem. In a box the volume is given by width times length times height, so the volume of the first box is 3*4*5=60 cubic inches.
In the second box, the volume is 6*8*10=480 cubic inches.
[tex]\frac{480}{60}=\frac{8}{1}=8[/tex]This means that in the big box you could place 8 peanuts for every peanut placed in the small box. If you need 500 peanuts to fill the small box, then for the big box:
