455.8125      or      [tex]\sf 455\frac{13}{16}[/tex]

follow the BODMAS rule:

Let's start!

(1+20-9/32)*((2+5)2+16/2)

remove brackets

(1+20-9/32)*(7*2+16/2)

division

(1+20-0.28125)*(7*2+8)

multiplication

(1+20-0.28125)*(14+8)

addition

(21-0.28125)*(22)

subtraction

(20.71875)*(22)

simplify

Answer:

The mean of 5 is because it includes the outlier more than the median

Step-by-step explanation:

Mean: ->             5

2 + 2 + 3 + 3 + 3 + 4 + 4 + 19 = ? / 8

40 / 8 = 5

Median: ->              3

Answer:

x = 6

Sorry if this answer is not correct, if it is or is not, please tell me in the comments!

Step-by-step explanation:

All of the angles add up to 180 degrees (since it is a triangle), so

(11x - 3) + (7x + 5) + (13x - 8) = 180

Then, combine the like terms.

31x - 6 = 180

Now, out goal is to separate the x from everything. To do that, we need to add 6 to 180.

31x = 186

Then divide by 31.

x = 6

(Feel free to replace x with 6 back in the previous equation to double check it!)

Answer:

  see attached

Step-by-step explanation:

The first application of the Pythagorean theorem is used to find the diagonal of one face. That is called 'a' in this problem. Then the second application of the Pythagorean theorem uses that value of 'a' along with the remaining prism dimension to find the space diagonal 'c'.

__

You don't actually have to find 'a', because you only need the value of a². Using the first equation to substitute into the second equation gives ...

Answer:

1. nonlinear

2. nonlinear

3. nonlinear

4. linear

5. linear

6. nonlinear

I think that is correct

Step-by-step explanation:

There is two ways you can do it.

1st . See if it is being multiplied, x cannot be the denominator, y cannot have a exponent and the x cannot be squared.

2nd - Use a graphing calculator and see if the line is straight, that is a linear equation and curved lines are nonlinear.

Answer:

A = picture attached

B = 51 in²

Step-by-step explanation:

I answered your other question, and I'm feeling lazy, so let me just copy + paste my answer here.

The picture attached is the answer for part A. You use the dimensions you already know from the first picture to fill in the net of the slice of pie.

Area of the triangle = 1/2 (base × height)

A = 1/2 (4 × 6) = 1/2 (24) = 12

The area of the triangle is 12. The top is a triangle, but the bottom is also a triangle with the same area. Therefore, the area of the two triangles combined is 24 in². Next, we have to find the area of the rectangle at the sides of the pie.

Area of rectangle = length × width

A = 5 × 2.5 = 12.

Since there are two rectangles with the same area on both sides of the pie, we can double it and get 25 in². We still have one rectangle left, the one at the back of the pie

A = 6 × 2.5 = 15

Add the areas altogether to get the answer.

24 + 12.5 + 15 = 51.5 in²

I hope this helps. Sorry if Part B's answer is wrong.

Answer:

1/20

Step-by-step explanation:

2/5 ÷ 1/8 = 1/20

Answer:

Step-by-step explanation:

B 1/20

Answer:

The answer is A.

Step-by-step explanation:

You know this because you can count the lines from the middle to the right
then, you count from the middle up.
the middle to the right is the 1st digit and the number that goes from the middle up is the 2nd.

it is not negative because then you would go to the left.

First we will take the time needed to make one chair by unitary method

then just multiply by how many chairs you want to calculate

Answer: It takes the machine 25 min to make 5 chairs and takes 160 min to make 32 chairs

Step-by-step explanation:  ok so for 5 chairs it will take 25min 2 chairs = 10 plus 2 = 20 + 1 chair = 25 min I am sorry if I make no sense i suck at explaining things. for 32 chairs you can do 32 TIMES 5 and that would be 160 HOPE THIS HELPS SORRY IF I DID NOT MAKE SENSE.

Answer:

Solve for x first.

In order to solve for x, you must set up an equation where the two interior angles (1 and 2) are equal to the exterior angle (3).

Interior angles.

Exterior angle:

Set up the equation:-

(3x + 7) + (2x + 24) = 6x + 10

Group and combine like terms;

(3x + 2x) + (7 + 24) = 6x + 10

5x + 31 = 6x + 10

Get rid of constants;

-10             -10

5x + 21 = 6x

-5x         -5x

21 = x, the value of 'x' is 21°.

Now we plug in the value of x into angle 3's equation.

∠3 = 6x + 10

∠3 = 6(21) + 10

∠3 = 126 + 10

∠3 = 136°, ∠3 = 136°.

Answer:

C. y = 4.5x

Step-by-step explanation:

The recipe calls for 4.5 teaspoons of sugar to make each cup of pudding. To make 2 cups of pudding, we would need two groups of 4.5 teaspoons, or 4.5+4.5=9 teaspoons of sugar. To make 3 cups of pudding, we would need 3 groups of 4.5 teaspoons, or 4.5+4.5+4.5=13.5 teaspoons of sugar. This repeated addition can be simplified as multiplication, because 4.5+4.5=4.5*2. We will need y teaspoons of sugar to make x cups of pudding. For each cup of pudding, we need 4.5 teaspoons of sugar. So, y=4.5x. If we made 2 cups of pudding (meaning x = 2 now), we fill that in and solve for y, which equals 9, as seen at the start.

Answer:

C.  y = 4.5x
