Someone pls help asap this is due tmrw !! x - 3y = -12 2x + 3y = 3

hram777 [196]

Answer:

Step-by-step explanation:

to solve this system of equations we will add them

x-3y=-12

2x+3y=3 now +3y-3y=0

3x=-12+3

3x=-9

x=-3

plug in the first equation

-3-3y=-12

-3y=-12+3

-3y=-9

y=3

In the right hexagonal pyramid below. The hexagonal base is regular and has sides that are 8 units long. The altitude of the pyr

Korvikt [17]

Answer:

The volume is 997.62 cubic units..

Step-by-step explanation:

We are given the following details:

The pyramid has a regular hexagonal base i.e. each side of hexagon is equal.

Side of hexagonal base, a = 8 units

Altitude of pyramid, h = 18 units

We have to find the volume of pyramid.

Formula:

$V = \dfrac{1}{3} \times B \times h$

Where, B is the area of base of pyramid.

h is the height/altitude of pyramid

To calculate B:

Here, base is a hexagon with side 8 units.

$\text{Area of hexagon, B }= 6 \times \dfrac{\sqrt{3}}{4}a^{2}$

Here, a = 8 units

$\Rightarrow B = 6 \times \dfrac{\sqrt{3}}{4}\times 8^{2}\\\Rightarrow B = 166.27\text{ square units}$

Putting values of B and h in Formula of volume:

$\Rightarrow V = \dfrac{1}{3} \times 166.27 \times 18\\\Rightarrow V = \dfrac{2992.89}{3} = 997.62\text{ cubic units}$

Hence, the volume is 997.62 cubic units.

If i work in a week 2 days cleaning and i will work 4 hours in a day and in 1 hour is 8$ how much will it be in a year

bagirrra123 [75]

Answer:

$3072

Step-by-step explanation:

It is given that :

I work for 4 hours everyday, working 2 days a week.

And in 1 hour , I get $8.

Therefore,

1 hour = $8

4 hours = 4 x 8

= $32

So, in 1 day working for 4 hours, I get $32.

∴ Working 2 days = 32 x 2

= $64

In 1 month, there are 4 weeks

So, in 4 weeks (or 1 month), I work for = 4 x 2

= 8 days

Therefore, in 8 days, I get = 8 x 32

= $256

Now there are 12 months in a year.

So, in 12 months , I will get = 12 x 256

= $3072

Therefore, in 1 year , I will get $3072.
