Answer:

D) 2.0

Step-by-step explanation:

We know that √2 = 1.414213562 ≈ 1.4, π ≈ 3.14, and √5 = 2.236067978 ≈ 2.2 . Next, I found out that √2π = 4.442882938 which rounds to 4.4. Then, I found out that 4.4 ÷ √5 equals to 1.96773982. So, if we round our answer to the nearest whole number, we will get 2.

Answer:

\boxed{Option \ D}

Step-by-step explanation:

\frac{\sqrt{2} \pi }{\sqrt{5} }

Where \sqrt{2} = 1.4 , π = 3.14 and \sqrt{5} = 2.24

Plugging in the values

=> \frac{(1.4)(3.14)}{2.24}

=> 4.396/2.24

=> 1.9

≈ 2.0

3/7 of the people living in the apartment building are men. 5/8 of the remaining are women. The rest are children. A total of 27
Vladimir [108]
People in building ---- x (men, women and children)
children --- y
men + women + children = x
(3/7)x + (5/8)(4/7)x + y = x
3x/7 + 5x/14 + y = x
times 14
6x + 5x + 14y = 14x
14y = 3x

y + 220 =x
sub into the other one
14y = 3(y+220)
11y = 660
y = 60
then 14(60) = 3x ---> x = 280

So we have 280 people in the building.

check: 3/7 of 280 are men = 120
leaving 160 women and children
5/8 of these ot 100 are women

so we have 120 men, 100 women and 60 children!

hope this is right! have a great. day

HELP PLEASE LOTS OF POINTS!!
Paladinen [302]

Answer:

<em>Thus, f and g are inverse functions</em>

Step-by-step explanation:

<u>Inverse Functions</u>

If two functions f(x) and g(x) are inverses, then it follows that:

f\circ g(x)=x

Or:

g\circ  f(x)=x

We are given

\displaystyle f(x)=\frac{1}{4}x-6

g(x)=4x+24

Let's test if they are inverse functions:

f\circ g(x)=\frac{1}{4}(4x+24)-6

Simplifying:

f\circ g(x)=x+6-6=x

Now find:

\displaystyle g\circ f(x)=4\left(\frac{1}{4}x-6\right)+24

Operating:

\displaystyle g\circ f(x)=x-24+24=x

Thus, f and g are inverse functions
