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.
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

The quality-control department of Starr Communications, the manufacturer of video-game cartridges, has determined from records that 1.6% of the cartridges sold have video defects, 0.7% have audio defects, and 0.4% have both audio and video defects. (a) What is the probability that a cartridge purchased by a customer will have a video or audio defect?
Answer:
The probability that a cartridge purchased by a customer will have a video or audio defect is 1.9%
Step-by-step explanation:
The given parameters in the question are;
The percentage of cartridges that have video defects, P(X) = 1.6%
The percentage of cartridges that have audio defects, P(Y) = 0.7%
The percentage of cartridges that have both audio and video defects, P(X and Y) = 0.4%
The probability is with regards to inclusive evets
The probability of inclusive events 'X' and 'Y' which are events that can happen at the same time are given as follows;
P(X or Y) = P(X) + P(Y) - P(X and Y)
Therefore, we have;
P(X or Y) = P(Video or Audio) = 0.016 + 0.007 - 0.004 = 0.019
∴ P(Video or Audio) = 1.9%
The probability that a cartridge purchased by a customer will have a video or audio defect = 1.9%
A piece on a game board moves forward 8 spaces on its first turn and moves backward 3 spaces on its second turn. If the pattern continues, how many turns will it take for the piece to move at least 30 spaces? Please help me!!!
Answer:
It will take 8 turns
Step-by-step explanation:
Answer:
11 turns
Step-by-step explanation:
A piece on a game board moves forward 8 spaces on its first turn and moves backward 3 spaces on its second turn. How many space it moves for each 2 turns?
Space it moves for each 2 turns = 8-3 = 5
The question is asking for how many turns will it take to move 30 spaces, since we know that the piece will move for 5 space each 2 turns(let's call this a cycle).
Cycle required for 30 spaces = 30/5 = 6
At this point, many will think that the no. of turns required is 6x2 = 12, but that's not the answer! Do you still remember how the cycle works? 1st up 5, 2nd down 3! On the 11th turn, the piece actually moved for 5x5 + 8 space = 33 spaces, which is greater than 30!
∴The answer is 11 turns

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

Which area model represents 0.4 x 0.7 = 0.28?
Answer:
the one with pink and white at the top, and the same one with purple and blue on the bottom
Step-by-step explanation:
The area model that represents 0.4 x 0.7 = 0.28 is the first graph, with pink color, purple colour, white colour and blue color.
Which area model represents 0.4 x 0.7 = 0.28?The area model that represents 0.4 x 0.7 = 0.28 is determined by observing the graph with 0.4 row or column times row or column with 0.7.
The solution of the expression is calculated as follows;
0.4 x 0.7 = 0.28
So we can see that the first graph has 0.4 column and 0.7 row, creating the desired result need for the product of 0.4 and 0.7.
Thus, the area model that represents 0.4 x 0.7 = 0.28 is determined as the first graph with pink color, purple colour, white colour and blue color.

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