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

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

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
hope this helps :)

Answer:
x-121
Step-by-step explanation:
Answer:
x² - 22x + 121
Step-by-step explanation:
(x-11)² is the same as (x-11)(x-11)
multiply the x in the first parentheses by x and -11 in the other parentheses and multiply the -11 in the first parentheses by x and -11 in the other parentheses and add all together
x²- 11x - 11x + 121
x² - 22x + 121
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

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?
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]
Tammy made $208 for 13 hours of work.
At the same rate, how much would she make for 9 hours of work?
Answer:
$144Step-by-step explanation:
1) Divide $208 by 13 hours to find out how much money she would make for 1 hour of work.
