Step-by-step explanation:

Given U = { a,b,c,d,e,f,g,h,i} P = {a,e,i} and Q = { b, a, g} List the elements of P' *

1 point

{b,c,d,f,g,h}

{a,e,i}

{b,a,g}

{a,b,c,d,e,f,g,h,i}

since P and Q share the same letter you're putting “A” in the middle where the two intersect. since U have B and Q have b we're putting it outside. so Q only supposed to have G. P is empty and U now have B,C,D,F,H.

p^1- p complement means everything outside of P so that will be b,c,d,f,g,h.

The total price for a computer and a
printer was $1039. If the computer
cost $750, how much did the printer
cost?

Answers

Answer:

$289

Step-by-step explanation:

If you know the cost of one of the two items, you can subtract that item from the total in order to find the price of the second item

So:   total price - computer price = printer cost

So:   $1039- $750 = $289

The printer is $289

Staples sells boxes of pens for ($10) and rubber bands for ($24). Leona ordered a total of 24 cartons for $210. How many boxes of each did Leona order? Hint: Let P = Pens.

Answers

Answer:

Leona ordered 19 boxes of pens and 5 rubber bands

Step-by-step explanation:

Let there are p pen and b rubber bands.

ATQ,

p+b = 24 ...(1)

and

10p+4b = 210 ...(2)

Multiply equation (1) by 10.

10p+10b = 240 ...(3)

Subtract equation (2) from (3).

10p+10b-(10p+4b ) = 240-210

6b = 30

b = 5

Put the value of b in equation (1).

p+5 = 24

p = 19

Hence, Leona ordered 19 boxes of pens and 5 rubber bands.

Answers

Answer:

x = 12

Step-by-step explanation:

(10x - 20)° + (6x + 8)°= 180°

(Linear pair angles)

(10x - 20 + 6x + 8)°= 180°

(16x - 12)°= 180°

16x - 12 = 180

16x = 180 + 12

16x = 192

x = 192/16

x = 12

Answer:

so x would equal 12

Step-by-step explanation:

(10x - 20)° + (6x + 8)°= 180°

so you are going to want to combine like terms which would be

10x and 6x, and 20,8

10x+6x=16x

20-8=12

16x-12=180

now you want to get 12 on the opposite side of the equal side so you add (since it is negative) 12 to each side

which gets rid of the first 12

16x=180+12

now you can add 180+12

and you get 192

so now we want to get x by itself in order to do that you must divide

you are going to divide by 16 an each side and the 16 cancels out the first 16

16x/16=192/16

x=192/16

and 192 divided by 16 is 12

so you answer is

x=12

Hope this made sense :)

2 y = (1865

Answers

Answer:

y = 18/5(11)

Step-by-step explanation:

If y varies directly as x, this is expressed as;

y∝x

y = kx

k is the constant of proportional constant

if y = 18 and x = 5

18 = 5k

k = 18/5

to get the expression that can be used to find the value of y when x is 11

y = kx

y = 18/5(11)

This gives the required expression

Step-by-step explanation:

I hope this helps :)

Answer:

We know that AD ≅ CD by the definition of kite. By the kite diagonal theorem, AC is perpendicular to BD. This means that angles AED and CED are right angles. We also see that ED ≅ ED by the reflexive property. Therefore, we have that ΔAED ≅ ΔCED by HL.

Step-by-step explanation:

We know that AD ≅ CD by the definition of kite.

- adjacent sides in a kite are congruent

By the kite diagonal theorem, AC is perpendicular to BD.

- the kite diagonal theorem states that diagonals of a kite form right angles because they are perpendicular to each other.

We also see that ED ≅ ED by the reflexive property.

- any side or angle congruent to itself is identified by the reflexive property

Therefore, we have that ΔAED ≅ ΔCED by HL.

- the triangles formed are all right triangles, so we can they that the two triangles are congruent to each other by the Hypotenuse Leg theorem.
