a conference hall has 33 rows.the last row contains 80 seats each row has two fewer seats than the row behind it.how many seats

ella [17]

Answer:

there are 84 seats in the second to the last row

Step-by-step explanation:

Given that

each row has two fewer seats than the row behind it

It means that

if first row has x seats then

no of seat in second row has (x-2) seats.

and similarly

no of seat in third row =no of seat in second row - 2seats.

no of seat in third row = (x-2) seat - 2 seats = x - 4 seats

_____________________________________________

Given that

last row has 80 seats

let the number of seat in first to the last row be x

then number of seat in last row = x-2

we know number of seat in last row = 80

thus

x - 2 = 80

x = 82

Thus,

the number of seat in first to the last row is 82

Similarly let the number of seat in second to the last row be y

then number of seat in first to the last row = y-2

since number of seat in first to the last row is 82

thus

y-2 = 82

y = 82 + 2 = 84

Thus, there are 84 seats in the second to the last row.

1. Katie worked 8 hours and was paid $74. Tim was paid $9.00 per hour. Who made more money per hour?

kkurt [141]

Katie made more money. Her hourly rate was $9.25 per hour . It already tells you how much Tim make an hour so all you have to figure out is how much Katie makes . 74 divided by 8 gives you 9.25 .

Find the coordinate point for A that would make ABDC a rhombus. coordinate plane with points B 3 comma 4, and C at 2 comma 1, an

mixer [17]

Answer:

B. (1, 3)

Step-by-step explanation:

We know the rhombus has perpendicular diagonals and the diagonals bisect each other.

The diagonals are AD and BC.

Note. The points C and D should have swapped coordinates. This becomes ABDC.

The midpoint of BC is:

([3 + 2]/2,[4 + 1]/2) = (2.5, 2.5)

Use A(x, y) and midpoint formula for the other diagonal AD:

(x + 4)/2 = 2.5 ⇒ x + 4 = 5 ⇒ x = 1
(y + 2)/2 = 2.5 ⇒ y + 2 = 5 ⇒ y = 3

Point A has coordinates (1, 3)

Correct choice is B
