Answer:

$32$ ${ft}^{2}$

Step-by-step explanation:

The area of a square rug = 64 ft²

First we will find the side of square rug = ${64}^{2} = {s}^{2}$

${s}^{2} = 8$

Perimeter of the rug = $4 \times 8$ $= 32$ ft²

Answer:

Mai lives 384 miles away from the mountains

Step-by-step explanation:

Let d represent distance between Mai's house and mountains and r represent Mai's rate while going to mountains.

We have been given that there was heavy traffic on the way there, and the trip to mountains took 8 hours.

$\text{Distance}}=\text{Time}\times \text{Speed}$

$d=8r...(1)$

We are also told that when Mai drove home, there was no traffic and the trip only took 6 hours. Her average rate was 16 miles per hour faster on the trip home.

$d=6(r+16)...(2)$

Upon equating equation (1) and equation (2), we will get:

$8r=6(r+16)$

$8r=6r+96$

$8r-6r=6r-6r+96$

$2r=96$

$\frac{2r}{2}=\frac{96}{2}$

$r=48$

Upon substituting $r=48$ in equation (1), we will get:

$d=8r\Rightarrow 8(48)=384$

Therefore, Mai lives 384 miles away from the mountains.

satela [25.4K]

Given:

Speed limit on a highway is 110 km per hour.

Let x be the speed of the car in time 't'

$t\ge\frac{x}{110}$

time when taken for a car to travel 132km.

$\begin{gathered} t\ge\frac{132}{110} \\ t\ge1.2\text{ hours} \end{gathered}$

It takes minimum 1 hour 12 minutes

statuscvo [17]

Answer:

$18.03 to nearest cent

Step-by-step explanation:

There are 52 weeks in the year so the weekly income = $37,500 / 52

So for a 40 hours week hourly pay = 37,500 / (52 * 40)

= $18.03 to nearest cent

Find the volume of the composite solid. Round your answer to the nearest tenth.

lakkis [162]

The "cylinder" has a diameter of 6, and therefore its radius is half that, or 3, thus

$\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h~~
\begin{cases}
r=radius\\
h=height\\
-----\\
r=3\\
h=11
\end{cases}\implies V=\pi (3)^2(11)\implies V=99\pi$
