Steve bought used and new video games from a website. The new games cost $54 each and the used games cost $9 each. He spent no more than $243 on the video games and he bought no more than 7 video games. Let x represent the number of new video games, and let y represent the number of used video games. Identify an ordered pair that is a solution to the system of inequalities. Interpret the meaning of the ordered pair within the context of the problem by selecting the appropriate explanation.

Answers

Answer:

y = 3 used games

x = 4 new games

Step-by-step explanation:

54x + 9y = 243

x + y = 7 then x = 7 - y

substitute for x:

54(7 - y) + 9y = 243

378 - 54y + 9y = 243

reduce:

378 - 45y = 243

subtract 243 from each side:

135 - 45y = 0

add 45y to each side:

45y = 135

divide both sides by 45:

y = 3

x = 7 - 3 = 4

check:

3+4 = 7

7 = 7

54(4) + 9(3) = 243

243 = 243

Answer:

1. 16π

2. 112π

3. 351.68

Step-by-step explanation:

Area of a circle = πr^2

Substitute...

=4^2π

=16π

To find the how much fluid it can hold, just basically find its volume. To do that, you mutiply the area of the base by the height. So...

16π*7=122π

You then just subsitute π by 3.14 so...

122(3.14)=351.68

An auditorium has 21 rows of seats. The first row has 18 seats and each succeeding row has 2 more seats than the previous row. How many seats are in the auditorium?

Answers

Answer:

798

Step-by-step explanation:

So, 21*{2*18 + (21-1)*2}/2

= 21*{36 + 20*2}/2

= 21*{36+40}/2

= 21*76/2

= 1596/2

= 798

Total number of seats is 798

Given that;

Number of seats in first row = 18

Number of rows = 21

Each row added number of seats then previous = 2

Find:

Total number of seats

Computation:

Total number of seats = Sn = (n/2)[2a + (n-1)d]

Total number of seats = Sn = (21/2)[2(18) + (21-1)2]

Total number of seats = (21/2)[36 + (20)2]

Total number of seats = (21/2)[36 + 40]

Total number of seats = (21/2)[76]

Total number of seats = (21)(38)

Total number of seats = 798

If q is the centroid of JKL, LN=72,JP=93, and MK=78, find each missing measure

Answers

*diagram is in the attachment below

Answer:

Step-by-step explanation:

Given:

LN = 72

JP = 93

MK = 78

Required:

LQ, QN, QP, JQ MQ, and KQ.

Solution:

Apply the centroid theorem to find each missing measure.

✔️LQ = ⅔(LN)

LQ = ⅔(72)

LQ = 48

✔️QN = ⅓(LN)

QN = ⅓(72)

QN = 24

✔️QP = ⅓(JP)

QP = ⅓(93)

QP = 31

✔️JQ = ⅔(JP)

JQ = ⅔(93)

JQ = 62

✔️MQ = ⅓(MK)

MQ = ⅓(78)

MQ = 26

✔️KQ = ⅔(MK)

KQ = ⅔(78)

KQ = 52

A ball is dropped from a height of 192 inches onto a level floor. After the third bounce it is still 3 inches off the ground. Presuming that the height the ball bounces is always the same fraction of the height reached on the previous bounce, what is that fraction?

Answers

Answer: The required fraction = [tex]\dfrac18[/tex]

Step-by-step explanation:

Let the required fraction = [tex]\dfrac{p}{q}[/tex]

Given: Initial height = 192 inches

Height of ball after second bounce = [tex]\dfrac{p}{q}\times192[/tex]

Height of ball after third bounce = [tex]\dfrac{p}{q}\times\dfrac{p}{q}\times192=192\dfrac{p^2}{q^2}[/tex]

After the third bounce it is 3 inches off the ground.

So,

[tex](\dfrac{p}{q})^2192=3\\\\\\(\dfrac{p}{q})^2=\dfrac{3}{192}\\\\(\dfrac{p}{q})^2=\dfrac{1}{64}\\\\(\dfrac{p}{q})^2=(\dfrac{1}{8})^2\\\\ \dfrac{p}{q}=\dfrac{1}{8}[/tex]

Hence, The required fraction = [tex]\dfrac18[/tex]

Answer:

the first one is 240

the second one is 280

the third one is 200

The answers that would be discarded would be 220, 360 and 500

Step-by-step explanation:

Hey There!

So for this problem all we have to do is plug in the hours worked and drones sold into the expression 10h+40d

For the first one we just plug in 8 for hours (because he worked 8 hours) and 4 for drones ( because he sold 4 drones )

so we would have 10(8) + 40(4)

10x8=80

40x4=160

160+80=240 So 240 would go with the first one

For the second one we plug in 4 for hours ( because he worked 4 hours) and 6 for drones ( because he sold 6 drones)

so we would have 10(4)+40(6)

10x4=40

40x6=240

240+40=280

So 280 would go with the second one

For the third one we plug in 12 for hours ( because he worked 12 hours) and 2 for drones ( because he sold 2 drones)

so we would have

12(10)+2(40)

12x10=120

2x40=80

120+80=200

so 200 would go with the third one
