1 answer:

6 0

$\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h\quad 
\begin{cases}
r=radius\\
h=height\\
-----\\
r=12.5\\
h=14
\end{cases}\implies V=\pi \cdot 12.5^2\cdot 14$

one of the fastest cars in the world was recently measured covering 5726 meters in 50 seconds what is the unit rate of speed of

IRISSAK [1]

ANSWER

114.52 meters per second

EXPLANATION

We have that the car covers a distance of 5726 meters in 50 seconds.

To find the speed, we have to use the formula for speed which is:

$\text{Speed = }\frac{dis\tan ce}{time}$

So, the unit rate of speed of the car is:

$\begin{gathered} \text{Speed = }\frac{5726}{50} \\ \text{Speed = 114.52 meters per second} \end{gathered}$

That is the unit rate of speed of the car in meters per second.

A car is traveling down a highway at a constant speed, described by the equation d=65t, where d represents the distance, in mile

Alexxx [7]

Answer:

Step-by-step explanation:

We are given an equation d = 65 t, where d represents the distance, in miles, that the car travels at this speed in t hours.

We know distance, speed and time relation

d = s * t.

Where d represents the distance, that the car travels at this speed in t at the speed s.

If we compare that relation with the given equation, we can see s = 65.

So,

a) The 65 tell us speed of 65 miles per hour in this situation.

b) Second part seems to be incorrect. Please check it again.

c) We are given distance = 26 miles.

Plugging d= 26 in the given equation.

26 = 65 t

Dividing both sides by 65, we get

26/65 = t

t= 0.4 hours.

So, it takes 0.4 hours or 0.4 * 60 = 24 minutes o travel 26 miles at this speed.

A wild horse runs at a rate of 8 miles per hour for 6 hours. Let yy be the distance, in miles, the horse travels for a given amo

spin [16.1K]

Answer:

$0\leq x\leq 6$

$0\leq y\leq 48$

Step-by-step explanation:

we are given

speed =8 mph

time = 6 hours

so, we have

$x=6$

now, we can find distance

distance = (speed)*(time)

$distance=8\times 6 miles$

$distance=48 miles$

so, we have

$y=48 miles$

so, our range for x and y can be

$0\leq x\leq 6$

$0\leq y\leq 48$
