Let sets A and B be defined as follows.

VashaNatasha [74]

<h3>Given</h3>

Set A: A = {-26, -25, -24, -23, - 22, - 21}
Set B: B ∈ {x: x is even, x ≥ 6 and x ≤ 20}

<em />

<em>Cardinality means the number of elements in the set.</em>

Cardinality of the set A:

n(A) = 6, since we can count 6 elements.

Set B has even numbers between 6 and 20, both included:

B = {6, 8, 10, 12, 14, 16, 18, 20}

Then its cardinality is:

n(B) = 8

To solve this we need to compare the elements of sets A or B with numbers given:

-22 ∈ A, True ⇒ -22 is listed as element of A
6 ∈ B, True ⇒ 6 is listed as element of B
- 21 ∉ A, False ⇒ - 21 is listed as element of A
2 ∈ B, False ⇒ 2 is not listed as element of B

Maymona book club is ordering new novels, She knows that the total cost of 6 books is $90, and 10 books cost $150. Write an equa

aleksandr82 [10.1K]

Answer:

Y=15x

Step-by-step explanation:

<h2>Okay so let's approach this problem!</h2><h2 />

X is books and Y is total cost

Let's find the slope!

Y2-Y1/ X2-X1

Just replace

$\frac{150 - 90}{10 - 6}$

$\frac{60}{4} = 15$

The slope is 15

$y = 15x + b$

Now replace x and y with coordinates and solve

$150 = 15(10) + b \\ 150 = 150 + b \\ - 150 \\ 0 = b$

The final equation:

y = 15x

That's it! If you have any questions please ask! Brainliest Appreciated.

the volume v of a tank varies directly with its height h a tank 12 ft High holds 300 cubic feet write an equation relating v &am

Liula [17]

v varies directly with height means

v/h=k were k is a constant

or also h/v=k where k is a constant (this is a different k than previous)

so if h=12 and v=300 then

h/v=12/300=1/25=k

so the relationhip could be h/v=1/25

if you di v/h, then

v/h=300/12=25/1=25=k

so the relationship could be v/h=25

Tony’s club is selling oranges to raise money. For every box they sell, they get 1 1/8 dollars profit. They have sold 75 boxes a

dmitriy555 [2]

Tony’s club is selling oranges to raise money. For every box they sell, they get 1 1/8 dollars profit. They have sold 75 boxes already. How many more boxes must they sell to raise 180 dollars?

Answer: We are given:

The amount of money Tony's club get for every box they sell $=1 \frac{1}{8} =1.125$ dollar

They amount of money Tony's club has raised by selling 75 boxes is:

$75 \times 1.125=84.375$ dollars

The amount of money Tony's club is required to raise = 180 dollars

The remaining need to be raised is :

$180-84.375=95.625$ dollars

Therefore, the number of more boxes to be sold are:

$\frac{95.625}{1.125}=85$

Hence, 85 more boxes they must sell to raise 180 dollars
