Answer:

350 sq ft

Step-by-step explanation:

Given that:

840 sq ft area has a bedroom, kitchen and bathroom.

Let the area of bedroom be x sq ft.

Then the area of kitchen will also be x sq ft.

Let the area of bathroom be y sq ft.

As per question statement:

x+y+x=840\\\Rightarrow 2x+y=840 ...... (1)

Tiles ordered to cover two kitchens and two bathrooms is 980 sq ft.

i.e.

2x+2y=980 ..... (2)

Subtracting equation (1) from (2):

i.e. (2) - (1):

y = 140 sq ft

Putting the value of y in (1):

2x+140=840\\\Rightarrow 2x =700\\\Rightarrow \bold{x=350\ sq\ ft}

Therefore, the carpet needed for each bedroom = <em>350 sq ft</em>

I'm horrible at this please help:((((​
wel

Step-by-step explanation:

You can insert different values of x to find y

For example:

x = 4

Plug in x into the equation

y = -1/2(4) + 5

y = -2 + 5

y = 3

So your point will be (4, 3)

If you do 1 more like this, you can draw a line between them. Or you can use Desmos to graph the line.

Hope this helped you!!

Researchers have found that after 25 years of age the average size of the pupil in a
laila [671]

Answer:

At 25 = 6.8612mm

At 50 years = 5.422mm

Step-by-step explanation:

Equation,

d = 2.115Logₑa + 13.669

d = diameter of the pupil

a = number of years

Note : Logₑa = In a (check logarithmic rule)

d = 2.115Ina + 13.669

1. At 25 years,

d = -2.115In25 + 13.669

d = -2.115 × 3.2188 + 13.669

d = -6.807762 + 13.669

d = 6.8612mm

At 25 years, the pupil shrinks by 6.86mm

2. At 50 years,

d = -2.1158In50 + 13.669

d = -2.1158 * 3.912 + 13.669

d = -8.2770 + 13.699

d = 5.422mm

At 50 years, the pupil shirks by 5.422mm

To save this question, I had to plug in the values into the equation.

Solving for Logₑa might be difficult, so instead I used Inx which is the same thing. Afterwards, i substituted in the values and solve the equation for each years.

How do you evaluate<br> lim(x-&gt;0) sin(9x)/6x?
irinina [24]
Hello,
we know that lim sin x /x =1 when x->0

lim sin(9x)/6x=1/6 lim sin (9x)/ x=1/6 lim sin( 9x) /(9x)  *9=9/6=3/2
