Tickets for the school play sell for S4 each. Which graph shows the relationship between the number of tickets sold

Fiesta28 [93]

Answer:

Step-by-step explanation:

Tickets for the school play sell for $4 each.

Number of tickers sold = x

Total income from the tickets = y

This means when x = 1, y = 4

SO when we sell 1 ticket (x = 1), we make $4 income (y = 4).

If we sell 2 tickets (x = 2), we will make $8 income (y = 8)

If we sell 3 tickets ( x = 3) , we will make $12 income (y = 12)

If we sell 4 tickets ( x = 4), we will make $16 income ( y = 16) etc.

Also note that when we sell 0 tickets (x = 0), we make no income (y = 0).

So if you create a graph, it should look something like this:

Evaluate 6C3. 18 20 60 120

melomori [17]

Answer:

Step-by-step explanation:

$nC_{r}=\frac{n!}{r!(n-r)!}\\\\6C_{3}=\frac{6!}{3!(6-3)!}\\\\=\frac{6!}{3!(6-3)!}==\frac{6!}{3!3!}\\=\frac{6*5*4*3!}{3!3!}\\\\=\frac{6*5*4}{3!}\\\\=\frac{6*5*4}{3*2*1}\\\\ =5*4=20$

Can someone check 1/10 and 9???? Thnx

fiasKO [112]

For numbers 9 and 10, we are dealing with negative exponents.

The rule of exponents states that any quantity b, taken to the power -n, equals the reciprocal of b, taken to the nth power.

Example: x⁻³ = 1 / x³

Number 9: ( 3 / y² ) ⁻³

Step 1: take the reciprocal:

( 3 / y² ) ⁻³ = ( y² / 3 ) ³

Step 2: distribute the exponent

( y² / 3 ) ³ = y⁶ / 27

Try to do number 10 on your own. If you have any questions, comment.

And wins a metal in the shape of a circle for finishing a marathon which statements about the metals are true use 3.14 for pi. S

PilotLPTM [1.2K]

Answer:

The true statements are:

C. If the metal has a radius of 2.5 inches then it has an area of 19.625 in.²

D. If the metal has a diameter of 3 inches and it has a circumference of 9.42 inches.

E. If the metal has a circumference of four pi inches then it has an area of four pi square inches

Step-by-step explanation:

Let us revise the rule of circumference and area of a circle

The formula of the circumference of a circle is C = π d, where d is the diameter of the circle OR C = 2πr, where r is the radius of the circle
The formula of the area of a circle is A = πr²
The radius of a circle is equal to half its diameter

A.

∵ The metal has a circumference of 7π inches

∵ C = 2πr

- Equate πd by 7π

∴ πd = 7π

- Divide both sides by π

∴ d = 7 inches not 3.5 inches

∴ A is not true

B.

∵ The metal has a circumference of 3π inches

∵ C = 2πr

- Equate 2πr by 3π

∴ 2πr = 3π

- Divide both sides by π

∴ 2r = 3

- Divide both sides by 2

∴ r = 1.5 inches

∵ A = πr²

∴ A = π(1.5)²

∴ A = 2.25π inches² not 9π inches²

∴ B is not true

C.

∵ The metal has a radius of 2.5 inches

∴ r = 2.5

∵ A = πr²

∵ π = 3.14

∴ A = 3.14(2.5)²

∴ A = 19.625 inches²

∴ If the metal has a radius of 2.5 inches, then its area is 19.625 in.²

∴ C is true

D.

∵ The metal has a diameter of 3 inches

∴ d = 3

∵ C = πd

∵ π = 3.14

∴ C = 3.14(3)

∴ C = 9.42 inches

∴ If the metal has a diameter of 3 inches, then its circumference

is 9.42 inches

∴ D is true

E.

∵ The metal has a circumference of 4π inches

∵ C = 2πr

- Equate 2πr by 4π

∴ 2πr = 4π

- Divide both sides by 2π

∴ r = 2

- Now you can find the area

∵ A = πr²

∴ A = π(2)²

∴ A = 4π

∴ If the metal has a circumference of 4π inches, then its area

is 4π inches²

∴ E is true

The true statements are:

C. If the metal has a radius of 2.5 inches then it has an area of 19.625 in.²

D. If the metal has a diameter of 3 inches and it has a circumference of 9.42 inches.

E. If the metal has a circumference of four pi inches then it has an area of four pi square inches
