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

5. Each pair of polygons below are similar. Show your work! Solve for x:
Answers
If you divide 16/40, you’ll find that that ratio is 2.5. So then you just multiply 16 x 2.5. You’ll get 18.
18 is the length of the top of the trapezoid.
You set 18=2x+4 and solve it algebraically. Subtract 4 from both sides.
14=2x
Divide by 2 and x=7
(You can also check that the ratio is right by 16/18 is the same decimal value as 40/45. You’ll get .88888...)

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]
Wallpaper was applied to one rectangular wall of a large room. Width: 42 ft length:25.5 ft. If the total cost of the wallpaper was $771.12, what was the cost, in dollars, of the wallpaper per square foot?
Answers
Answer:
$825869.52
Step-by-step explanation:
Given that,
Width of the rectangle, b = 42 ft
Length of the rectangle, l = 25.5 ft
The area of a rectangle is given by :
A = lb
So,
A = 42 ft × 25.5 ft
A = 1071 ft²
The total cost of the wallpaper was $771.12 . So,
Cost = 1071 × 771.12
= $825869.52
So, the cost of wallpaper per square foot is equal to $825869.52.

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

Jack has $500 in a bank account that will earn 3% interest every year. Diane has $100 in an investment account that will earn 12% every year. How many years will it take for Diane's account balance to overtake Jack’s?
Answers
Answer:
20 years
Step-by-step explanation:

A=100(1+.12)^20

It took her 20 years to overtake.
Answer:
Simple interest = NeverCompound interest = 19 years and 4 monthsStep-by-step explanation:
Jack
Initial amount = $500Interest rate = 3% = 0.03Yearly interest = 0.03*500 = $15
Diane
Initial amount = $100Interest rate = 12% = 0.12Yearly interest = 0.12*100 = $12
Diane's initial amount and yearly interest amount are both less than of Jack's.
It means her balance will never overtake Jack's.
=======================
It is not mentioned in the question but let's assume it is compound interest which is annually compounded.
Then after x years their balance will be:

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
