Given the sets above, select all (or the null set) of the element of: B

Answers

Given:

Universal set = {a, b, c, d, e, f, g, h}

A = {a, b, c, d}

B = {a, d, e}

C= {c, f, g, h}

To find:

The elements of set B'.

Solution:

Let universal set be U.

U = {a, b, c, d, e, f, g, h}

We know that,

Compliment of a set = Universal set - Set

It means,

[tex]B'=U-B[/tex]

[tex]B'=\{a, b, c, d, e, f, g, h\}-\{a,d,e\}[/tex]

[tex]B'=\{b, c,f, g, h\}[/tex]

Therefore, only b, c, f, g, h are the elements of set B'.

-9x + 3 > 39 OR - 5x + 6 < 16

Answers

9514 1404 393

Answer:

(-∞, -4) ∪ [-2, ∞)

Step-by-step explanation:

The solution to the first inequality is ...

-9x +3 > 39

-9x > 36 . . . . . subtract 3 from both sides

x < -4 . . . . . . . divide both sides by -9; reverse > to < because -9 is negative

The solution to the second inequality is ...

-5x +6 ≤ 16

-5x ≤ 10 . . . . . . . subtract 6 from both sides

x ≥ -2 . . . . . . divide both sides by -2; reverse ≤ to ≥ because -2 is negative

These solution sets are disjoint. The solution of the OR of these inequalities is the union of the solution sets. The graph is shown below. In interval notation, it is described by ...

(-∞, -4) ∪ [-2, ∞)

The -2 has a square bracket because it is included in the set. The curved bracket at -4 indicates it is not included.

Elizabeth practices the piano 1470 minutes in 5 weeks. If t represents the total time she practices for any number of days, d, write a proportional equation for t in terms of d that matches the context.

Answers

Using proportions, it is found that the proportional equation for t in terms of d that matches the context is:

[tex]t = 42d[/tex]

Elizabeth practices the piano 1470 minutes in 5 weeks, hence, each day, consdering a week has 7 days, the amount of time she practices is:

[tex]a = \frac{1470}{35} = 42[/tex]

Hence, the proportional equation, considering t the time in minutes and d the number of days, is:

[tex]t = 42d[/tex]

In the diagram of collin ear points, LP=27, LM=NP, and MN=3
16. LM=
17. NP=
18. MP=
19. NL=

Answers

Answer:

Step-by-step explanation:

Given:

LP = 27

LM = NP

MN = 3

16). LP = LM + MN + NP

27 = LM + 3 + LM

27 = 3 + 2(LM)

LM = 12

17). Since, LM = NP

NP = 12

18). Since, MP = MN + NP

MP = 3 + 12

MP = 15

19). NL = LM + MN

NL = 12 + 3

NL = 15

An air traffic controller is tracking two planes. To start, Plane A is at an altitude of 4385 feet and Plane B is at an altitude of 5000 feet. Plane A is gaining altitude at 55.5 feet per second and Plane B is gaining altitude at 45.25 feet per second.

How many seconds will pass before the planes are at the same altitude?
seconds
What will their altitude be when they're at the same altitude?
feet

Answers

Answer:

60 seconds, 7715 feet

Step-by-step explanation:

Plane A and B start out 615 feet apart, and we find this by subtracting the height of plane A from plane B, getting 5000-4385=615. Now we have to find how many more feet of altitude plane A is gaining per second over plane B.

To find this we subtract 45.25 from 55.5 and get 10.25 feet per second. Now to find out how many seconds until they'll be at the same altitude we simply divide 615 by 10.25, getting 60 seconds.

For the second part, to find the altitude at this point, we simply multiply the altitude gain of one of the planes per second by the time of 60 seconds to get how much altitude they gained over that time, and add it to the starting altitude. Doing this with plane B we get 45.25*60=2715, and we add that to 5000 to get the final answer of 7715.

AB/PQ = 2/3

AC/PR = 2/3

BC/QR = 2/3

Step-by-step explanation:

Since it says that the tiangles are similar, then it means that AB=PQ, AC=PR, BC=QR.

So, AB/PQ = 6/9 = 2/3

And, AC/PR = 8/12 = 2/3

Also, BC/QR = 10/15 = 2/3

8x + y = 17
5x + 5y = –20

Answers

Answer:

X=3 Y=-7

Step-by-step explanation:

You can solve a system of equations a number of ways. Substitution makes the most sense in this case. Take the top equation and set it equal to y making it: y=17-8x

Then substitute y in the bottom equation for the y solved in the top. So,

5x + 5(17-8x) = -20

Then solve for x

x=3

Now that we know x, plug it back into the equation for y

y = 17 - 8(3)

y = -7

So your solution is (3, -7)

Answer:

Step-by-step explanation:

40x + 5y = 85

-5x - 5y = 20

35x = 105

x= 3

15 + 5y = -20

5y = -35

y = -7

The selling price of a refrigerator is $487.20. If the mark up is 5% of the dealers cost what is the dealers cost of the refrigerator

Answers

Answer:

$464

Step-by-step explanation:

Let the cos be x, then selling price is:

x + 5% = x*1.05 = 1.05x

We have the selling price $487.20

1.05x = 487.20x = 487.20/1.05x = 464

Cost price is $464

pls help me, i’ll give brainly

Answers

Answer/Step-by-step explanation:

First, find the slope (m) of Line L using the points (0, 5) and (2, 1):

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - 5}{2 - 0} = \frac{-4}{2} = -2 [/tex]

Slope (m) = -2

✔️Since the line is parallel bro Line L, it would also have the same slope value of -2.

We can use the slope (m) and a point (a, b) of the line to find its equation using the point-slope formula, y - b = m(x - a).

Substitute (a, b) = (3, 0), and m = -2 into y - b = m(x + a):

Thus,

✅y - 0 = -2(x + 3)

Rewrite equation in slope-intercept form

y = -2(x + 3)

✅y = -2x - 6
