Answer:

[tex]B = \{3,4,5,6\}[/tex]

Step-by-step explanation:

Given

[tex]A = \{1,2,3,4,5\}[/tex]

[tex]A\ n\ B = \{3,4,5\}[/tex]

[tex]A\ u\ B = \{1,2,3,4,5,6\}[/tex]

Required

Find set B

[tex]A\ n\ B = \{3,4,5\}[/tex] means that the common elements in A and B are 3, 4 and 5.

This implies that:

A subset of B are:

[tex]x = \{3,4,5\}[/tex]

And it also means that [tex]\{1,2\}[/tex] are not elements of B.

The remaining elements (y) of B are then calculated as follows:

[tex]y = (A\ u\ B) - (\{1,2\}\ u\ x)[/tex]

This gives:

[tex]y = \{1,2,3,4,5,6\} - (\{1,2\} u \{3,4,5\})[/tex]

[tex]y = \{1,2,3,4,5,6\} - \{1,2,3,4,5\}[/tex]

Remove common elements

[tex]y = \{6\}[/tex]

Hence, the set B is:

[tex]B = \{\{x\},\{y\}\}[/tex]

[tex]B = \{3,4,5,6\}[/tex]

Answer: The shape below is formed from a rectangle measuring 18 cm by 24cm from which a rectangle of length 8.6cm has been removed

Step-by-step explanation:

initial Perimeter of rectangle =  2 (24 + 18)  = 84 cm

After removing rectangle of  length 8.6 cm

two sides of 8.6 cm are added in perimeter

Perimeter of Shape

= 2 (24 + 18)  + 8.6 + 8.6

= 84 + 17.2

= 101.2  cm

perimeter of the shape = 101.2  cm

Step-by-step explanation:

The way that I would do this is by plugging in 2 values for x, double it then see what happens

Let's say 2

So when we plug in 2 for x we get

5*2=y

y=10

Then what happens when we double x?

Our new equation would be 10x

*we get this becase 5*2=10*

so we plug in to for y=10x and get y=10*2 which is 20. Our answer doubled and therefore the answer is A

Let's do the same thing for number 2 with the number 10

5/10=.5

Then when the value of x triples our new equation is 5/3x

we use this formula and get 5/(3*10)=5/30=1/6=.1666667

This is equal to dividing it by 3 which means the answer is D

Answer:

hm looks like the equation is 5/8

Step-by-step explanation:

i think its 5/8th of a second right????????

Answer:

Add '-10x' to each side of the equation.

60 + -10x = 10x + -10x

Combine like terms: 10x + -10x = 0

60 + -10x = 0

Add '-60' to each side of the equation.

60 + -60 + -10x = 0 + -60

Combine like terms: 60 + -60 = 0

0 + -10x = 0 + -60

-10x = 0 + -60

Combine like terms: 0 + -60 = -60

-10x = -60

Divide each side by '-10'.

x = 6

Simplifying

x = 6

Answer: It would be less expensive for Mr. Steiner to purchase the batteries in 12-packs.

Step-by-step explanation:

ii. The difference between the costs of one battery from each pack is $0.02 or 2 cents.

Step-by-step explanation:

A way to respond to these questions is as follows:

To purchase 60 AA batteries, we have to:

Buy 3 20-pack of AA batteries (since 3 * 20-pack = 60 batteries), or

Buy 5 12-pack of AA batteries (since 5 * 12-pack = 60 batteries).

We also know that a 20-pack costs $12.49 and a 12-pack costs $7.20.

Part 1: Which package is less expensive?

Case 1: How much does it cost 3 20-pack of AA batteries?

Three packages cost: 3 * $12.49 = $37.47

Case 2: How much does it cost 5 12-pack of AA batteries?

Five packages cost: 5 * $7.20 = $36.00

Then, it is less expensive for Mr. Steiner to purchase 5 12-packs batteries (which cost $36) than 3 20-packs batteries (which cost $37.47).

Part 2: Difference between the costs of one battery from each pack

The question we need to answer here is, how much does it cost one battery from each pack?

For this, we need to divide the total costs that we obtained in Part 1 by the total of batteries to be purchased, that is, 60.

Then, for Case 1, the cost of one battery for this purchase is:

[tex]\frac{37.47}{60battery} = \frac{0.62}{battery}[/tex] or 62 cents per battery.

For Case 2, the cost of one battery for this purchase is:

[tex]\frac{36.00}{60battery} =\frac{0.60}{battery}[/tex] or 60 cents per battery.

So, the difference between the costs of one battery from each pack is:

62 cents per battery - 60 cents per battery = 2 cents per battery.

Then, one battery from the 12-pack is less expensive than one battery from the 20-pack in 2 cents.

Answer:

953.78in^3 of grain

Step-by-step explanation:

You use the equation π r^2 h to find the volume of the cylinder

r =  radius of the base = 9/2

= 4.5 in  and the height h = 15 in

the volume is 3.14 * 4.5^2 * 15

= 953.78 in^3.

The amount of grain can this container hold is 953.78 inch³, So option 'B' is the correct answer to the following question.

What information do we have?

Diameter of cylinder = 9 in

Radius of cylinder = 9 / 2 in

Radius of cylinder = 4.5 in

Height of cylinder = 15 inch

Volume of cylinder = Amount of grain can this container hold

Amount of grain can this container hold = πr²h

Amount of grain can this container hold = (3.14)(4.5)²(15)

Amount of grain can this container hold = 953.78 inch³

Find our more information about 'Volume'.

Answer:

2A/h - a = b

Step-by-step explanation:

Using A= 1/2(a+b)h

Divide both side by h

⇒A/h = 1/2(a + b)

Mutiply both sides by 2

⇒2A/h = a + b

Take the 2 over to the other side

2A/h - a = b

Keep in mind, that the (a) is not on the bottom, rather on its own

Answer:

b=42 ( base angles are equal)

a=24

then taking a as refrence angle

tan24=p/b

tan24=a/42

a= -89.66( but length cant be negative so )

a=89.66

Answer:

1/3

Step-by-step explanation:

(-4-(-5))/(3-0) = 1/3

Answer:

Linear measures (measures of length and width) are at a scale of 1:500; or

for every "real life" yard, the map would be "1/500" yard long.

Thus for measures of area, such as hectares, the map would would be 1/(500)² as big.

So: (3/5 = .6) hectares would be .6/(500)² hectares = .0000024 hectares.

And since 1 hectare = 15500031 in²;

the area on the map would be 15500031 (.0000024) in² ~ 37.2 in² ~ 240 cm²
