Eddi Din [679]

Answer:

Hours in first month = 8

Step-by-step explanation:

AS it is given

He volunteered fr the first month = x hours

He volunteered for the second month = 12/3 times of first month

which will be = 12/3 * x

Total Hours volunteered = 40 hours

Now according to the given conditions

Volunteered first month + volunteered second month = total

putting this gives

x + 12/3 8 x = 40

as 12/3 = 4 so

it becomes

x + 4x = 40

solcing it will gives

5x = 40

x = 40/5

x = 8

So Numbers of hours worked in first month are 8

I hope this help you! :)

Answer:

27°

Step-by-step explanation:

XWY and VWY are supplementary

∴ XWY + VWY = 180°

∴ XWY = 180° - VWY

XYW and ZYW are supplementary

∴ XYW + ZYW = 180°

∴ XYW = 180° - ZYW

ΔXWY is a right triangle at X

∴ XWY + XYW = 90°

∴ 180° - VWY + 180° - ZYW = 90°

∴ 180° - 6x + 180° - 4x = 90°

∴ 360° - 10x = 90°

∴ 10x = 270°

∴ x = 27°

mihalych1998 [28]

Answer:

The expression for the total amount of tickets sales can be give in dollars as :

⇒ $130y+73,500$

Step-by-step explanation:

Given:

Cost of a ticket in standing arena = $210

Cost of a ticket for a seat = $130

Total people that can accommodate in standing arena = 350

Total number of seats in the concert = $y$

To write the expression for the total amount of tickets sales if the concert is sold out.

Solution:

The concert is sold out. This means 350 tickets for standing arena and $y$ tickets for seats are sol out.

Using unitary method to find the total cost.

If a ticket in front stage arena costs = $210

Then, 350 such tickets will cost = $350\times \$ 210=\$ 73,500$

If a ticket for a seat costs = $130

Then, y such tickets will cost = $y\times \$ 130=\$ 130y$

Total amount of ticket sales can be given as:

$\textrm{Total cost of seat tickets in dollars sold + Total cost of front stage tickets in dollars sold}$

⇒ $130y+73,500$
