Answer:
Step-by-step explanation:
1 hour equals 60 minutes
Find out how many pages per minute by dividing 1,520 pages by 60 minutes.
= 25.3333333
Therefore the machine prints 25.333333 pages per minute.
Multiply 25.3333333 by 15 minutes = 380
The machine can print 380 pages in 15 minutes.
You can check your work by finding out how many fifteen minute periods are in an hour (60/15=4), and multiplying 380x4
Since 15x4 is 60 and you can print 1520 pages in 60 minutes, you should be able to multiply 380x4 and get 1520 (spoiler alert! 380x4 is 1,520)
Hope that helped!

What is the mean absolute deviation of the data 10, 17, 20, 12, and 16? Round to the nearest whole number
Answer:
3.5
Step-by-step explanation:
where n is the number of observed values, x-bar is the mean of the observed values and xi are the individual values.
Answer:
The answer is 4
[tex]s = \sqrt{\frac{\Sigma^n_i_=_1(x_i-x)^2}{n-1} }[/tex]
Turn the equation into a simpler form
[tex]s = \sqrt{\frac{SS}{n-1} }[/tex]
[tex]s = \sqrt{\frac{64}{5-1} }[/tex]
[tex]s = \sqrt{\frac{64}{4} }[/tex]
[tex]s = \sqrt{16}[/tex]
That said, we know the square root of 16 is 4, so 4 would be your answer.

19. In a "TriboNcci" sequence, each number after the third number is the sum of the preceding three numbers. For example, if the first three numbers are 5,6, and 7 , then the fourth number is 18 because 5 + 6 + 7 = 18, and the fifth number is 31 because 6 + 7 + 18 = 31. The first five numbers of another TriboNcci sequence are P, Q, 86, 158, and 291 in that order. What is the value of P ?
Answer: each number after the third number is the sum of the preceding three numbers. For example, if the first three numbers are 5, 6, and 7, then the fourth number is 18 because 5 + 6 + 7 = 18 and the fifth number is 31 because 6 + 7 + 18 = 31.

Mr. Jackson is ordering kazoos for his second, third, and fourth grade music classes.
The kazoos come in boxes of 8. There are 26 second graders, 24 third graders, and 30 fourth graders.
How many boxes of kazoos does Mr. Jackson need to order so that every student will receive a kazoo?
Enter your answer in the box.
Answer:
The boxes of kazoos Mr. Jackson needs to order (26 + 24 + 30) ÷ 8.
We have given that,
There are 26-second graders, 24 third graders, and 30 fourth graders.
What is the expression?
An expression, in math, is a sentence with a minimum of two numbers and at least one math operation contain in it.
The amount of kazoos needed is 1 for every student
26 + 24 + 30
Since 8 come in each box, you divide by 8
To get your answer of (26 + 24 + 30) ÷ 8.

What will be the result of substituting 2 for x in both expressions below? One-half x + 4 x + 6 minus one-half x minus 2 Both expressions equal 5 when substituting 2 for x because the expressions are equivalent. Both expressions equal 6 when substituting 2 for x because the expressions are equivalent. One expression equals 5 when substituting 2 for x, and the other equals 2 because the expressions are not equivalent. One expression equals 6 when substituting 2 for x, and the other equals 2 because the expressions are not equivalent.
Answer:
one expression equals 5 when so substituting 2for x and the other equals 9 because the expression are not equal.

Answer:
59°
Step-by-step explanation:
The total of all the angles in a triangle should amount to 180°. So:
64° + 57° = 121°
180° - 121° = 59°

Answer:
24 Units Cubed
Step-by-step explanation:
Start with the face of your 3D shape, which has a length/width of 3 units and a height of 4 units. Then look at the visible side of your figure, in this case it is the right side. You can see it's width/length of 2 units, so multiply 4x3x2, and in this case 4x3=12 and 12x2 is 24. making your answer 24 units cubed.

A train travels at an average speed of 80 km/h. How long will it take the train to travel 320 km?
Answer:
4 hours
Step-by-step explanation:
If the train travels at ~80 kilometers per hour, you just divide the total distance (in this case, 320 kilometers) by the speed traveled (80 kilometers). 320/80 = 4 hours.

Answer:
Equal to
Step-by-step explanation:
Hello!
Let's simplify the left side:
- ( -9 ) 9Remember that the negative sign also means opposite, so the opposite of negative 9 is positive 9.
Let's simplfy the right side:
| - 9 |9Remember that in an absolute value bracket, any positive value stays positive, but any negative value turns to the positive value.
So the inequality is 9 _ 9
Therefore the sign should be "=" as 9 is equal to 9.

Find the surface area of the pyramids
first one:
The surface area of a pyramid can be found using the formula:
Surface Area = (1/2) x Perimeter of Base x Slant Height + Base Area
Since the side lengths of the base are equal, the perimeter of the base is:
Perimeter of Base = 4 x Side Length
Perimeter of Base = 4 x 9 = 36 feet
To find the slant height, we can use the Pythagorean theorem:
Slant Height^2 = Height^2 + (1/2 x Side Length)^2
Slant Height^2 = 12^2 + (1/2 x 9)^2
Slant Height^2 = 144 + 20.25
Slant Height^2 = 164.25
Slant Height = 12.81 feet
The base area can be found using the formula for the area of a square:
Base Area = Side Length^2
Base Area = 9^2 = 81 square feet
Plugging in the values into the formula for surface area:
Surface Area = (1/2) x 36 x 12.81 + 81
Surface Area = 218.16 square feet
So the surface area of the pyramid is 218.16 square feet.
second one:
The surface area of a pyramid can be found using the formula:
Surface Area = (1/2) x Perimeter of Base x Slant Height + Base Area
Since the side lengths of the base are equal, the perimeter of the base is:
Perimeter of Base = 4 x Side Length
Perimeter of Base = 4 x 8 = 32 meters
To find the slant height, we can use the Pythagorean theorem:
Slant Height^2 = Height^2 + (1/2 x (Side Length1 + Side Length2))^2
Slant Height^2 = 3.5^2 + (1/2 x (8 + 4))^2
Slant Height^2 = 12.25 + 36
Slant Height^2 = 48.25
Slant Height = 6.94 meters
The base area can be found using the formula for the area of a square:
Base Area = Side Length^2
Base Area = 8^2 = 64 square meters
Plugging in the values into the formula for surface area:
Surface Area = (1/2) x 32 x 6.94 + 64
Surface Area = 107.52 square meters
So the surface area of the pyramid is 107.52 square meters.
Heres another brainly question giving 20pts!!
Answer:
We are given an area and three different widths and we need to determine the corresponding length and perimeter.
The first width that is provided is 4 yards and to get an area of 100 we need to multiply it by 25 yards. This would mean that our length is 25 yards and our perimeter would be 2(l + w) which is 2(25 + 4) = 58 yards.
The second width that is given is 5 yards and in order to get an area of 100 yards we need to multiply by 20 yards. This would mean that our length is 20 yards and our perimeter would be 2(l + w) which is 2(20 + 5) = 50 yards.
The final width that is given is 10 yards and in order to get an area of 100 yards we need to multiply by 10. This would mean that our length is 10 yards and our perimeter would be 2(l + w) which is 2(10 + 10) = 40 yards.
Therefore the field that would require the least amount of fencing (the smallest perimeter) is option C, field #3.

PLEASE HELP I CURRENTLY HAVE AN F BUT I WONT ANYMORE IF YOU HELP ME
(If you can help me with my Graphing Coordinations question please do!)
Answer:
x = 10
Step-by-step explanation:
Both obects are similar right. That means that they must have similar angles, similar sizes and similar scale factors.
For me by just looking at the figires I can conclude a similar scale factor which is 1.7. However we are going to calculate the scale factor.
First we must take notice that the triangle D'E'F' is an enlargement. So to find the scale factor we must the same sides of both triangle and divide the larger sid by the smaller side.
68 ÷ 40 = 1.7
Now that we have the scale factor (1.7) we can now find x.
The similer side D'F' = 17 and DF = x.
We are gonna use the scale factor to divide D'F' to find DF.
17 ÷ 1.7 = 10
Therefore x is 10

Susan is buying 5 and a half pies from the market. Write this amount as a mixed number, improper fraction, decimal and percent.
Mixed Number:
[tex]5\frac{1}{2}[/tex] or 5 1/2
Improper fraction:
2x5+1=11
[tex]\frac{11}{2}[/tex] or 11/2
Decimal:
5.5
5.5 because 5 is whole number, and then, 5 tenths because 5 is half of 10.
Percent:
1 whole = 100%
100% x 5 = 500%
500% + 50% (1/2) = 550%
550%
