Answer:

200 notebooks

Step-by-step explanation:

Provided Information:

1) 8 out of every 500 notebooks contain a defect

2) 2500 notebooks are produced per day

We need to find out how many defective notebooks are produced per day:

1) 2500 ÷ 500 = 5

2) 8 x 5 = 40

Next we need to find out how many notebooks are defective per week:

1) 40 x 5 = 200 defective notebooks per week

Answer:

B. Sometimes

Step-by-step explanation:

When there is an odd set of numbers the mean will ALWAYS be one of the data values.

When there is a even set of numbers the mean will sometimes be one of the data values.

This means only SOMETIMES it can go with date values!

Answer:

VA = 2/3πrB²hB

Step-by-step explanation:

Let the volume of cosA ad cone B be expressed as;

Va = 1/3πra²ha

Vb = 1/3πrb²hb

If the radius of the base of cone A is twice as large as the radius of the base of cone B

rA = 2rB

If the height of cone B is twice the height of cone A, then;

hB = 2hA

hA = hB/2

Recall that;

VA = 1/3πrA²hA

VA = 1/3π(2rB)²(hB/2)

VA = 1/3π*4rB²(hB/2)

VA = 2/3πrB²hB

This gives the volume of cone A

Answer:

Step-by-step explanation:

x+90+90+78=360(sum of 4 angles is always 360 degree)

x+258=360

x=360-258

x=102

Answer:

[tex] {x}^{o} = {102}^{o} [/tex]

Step-by-step explanation:

Hint:

sum of angles = 360°

Simplify:

[tex] {x}^{o} + {78}^{o} + {90}^{o} + {90}^{o} = {360}^{o} \\ {x }^{o} + 258^{o} = {360}^{o} \\ {x}^{o} = {360}^{o} - {258}^{o} \\ {x}^{o} = {102}^{o} [/tex]

Answer:

27/2 is the value of the number.

Let the number be x.

According to the question,

12(x-12)=18

x-12=18/12

x-12=3/2

x=3/2+12

x=3/2+24/2

x=27/2

HOPE IT HELP :)

Answer:

13.5    27/2      13 (1/2)   all the same

Step-by-step explanation:

(x-12)x12  = 18

12x-144 = 18

12x = 162

x = 162/12 = 27/2  = 13(1/2) = 13.5

Answer:

The 5th day must be 90

Step-by-step explanation:

The first 4 days averaged out to 80

You can find their total just by multiplying by 4. That won't tell you the exact values, but it will tell you their total when you add the 4 of them together.

80*4 = 320

Now you need to add another day into the mix. Call it x

320 + x

Now there are 5 days, not 4, and the new total is 82.

(320 + x) / 5 = 82          Multiply both sides by 5

5*(320 + x) / 5 = 82 *5

320 + x = 410                 Subtract 320

-320        -320

x = 90

Answer:

D

Step-by-step explanation:

180 degrees in a triangle

102+(x+6)+(x+15)=180

remove parenthesis and combine like terms

123+2x=180

subtract 123 from both sides

2x=57

divide

x=28.5

substitute x for its actual value

28.5+6

angle A= 34.5

28.5+15

angle B= 43.5

Answer:

3

Step-by-step explanation:

Angles ( 17x - 1 ) and ( 15x + 5 ) are alternate interior angles.

Alternate interior angles are equal.

17x - 1 = 15x + 5

17x - 15x = 5 + 1

2x = 6

x = 6 / 2

x = 3

Answer:

R'=(-3,6)

Q'=(-3,-3)

S'=(7,6)

T'=(7,-3)

Answer:

see explanation

Step-by-step explanation:

A translation of 7 units right means adding 7 to the x- coordinate. The y- coordinate remains unchanged, then

Q (- 10, - 3 ) → Q' (- 10 + 7, - 3 ) → Q' (- 3, - 3 )

R (- 10, 6 ) → R' (- 10 + 7, 6 ) → R' (- 3, 6 )

S (0, 6 ) → S' (0 + 7, 6 ) → S' (7, 6 )

T (0, - 3 ) → T' (0 + 7, - 3 ) → T' (7, - 3 )

Answer:

a) The area of each square is 81 square centimeters.

b) The side length of the square is 9 centimeters.

c) The perimeter of the rectangle is 54 centimeters.

Step-by-step explanation:

Statement is incomplete. After some web research we conclude that the complete statement is the following:

A rectangle is formed by placing two identical squares side by side. The area of the rectangle is 162 square centimeters. Find:

a) The area of each square.

b) The side length of each square.

c) The perimeter of the rectangle.

a) The area of the each square is half the area of the rectangle. Hence, the area of each square is 81 square centimeters.

b) The area formula for squares ([tex]A[/tex]), in square centimeters, is:

[tex]A = l^{2}[/tex] (1)

Where [tex]l[/tex] is the side length of the square, in centimeters.

If we know that [tex]A = 81\,cm^{2}[/tex], then the side length of the square is:

[tex]l = \sqrt{A}[/tex]

[tex]l = \sqrt{81\,cm^{2}}[/tex]

[tex]l = 9\,cm[/tex]

The side length of the square is 9 centimeters.

c) The perimeter formula of the rectangle ([tex]p[/tex]), in centimeters, is presented below:

[tex]p = 6\cdot l[/tex]

[tex]p = 6\cdot (9\,cm)[/tex]

[tex]p = 54\,cm[/tex]

The perimeter of the rectangle is 54 centimeters.

Here is your answer and explanation have a good day

Step-by-step explanation:

The total number of different outfits Joseph can choose is A = 32 outcomes

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

The number of pairs of pants = 2 pairs

The number of pairs of t-shirts = 8 pairs

The number of pairs of shoes = 2 pairs

And , the total number of outcomes A = 2 x 8 x 2

On simplifying the equation , we get

The different outfits does Joseph can choose A = 32 outfits

Hence , the equation is A = 32 outfits

A - Positive linear association

Step-by-step explanation:

You can see that the overall direction of the graph is going up, therefore, this graph has a postivie association.

Answer:

a= 32

Step-by-step explanation:

Since "a" is a part of a supplementary angle (An angle that adds up to 180º)

What you would need to do is add 58º and 90º (90º because the right angle = 90)

so 58+90 = 148

Then you would subtract 148 from the total of the angle (Which is 180)

so 180 - 148 = 32, And that shows that a = 32
