Answer:

The speed of car in miles per minute is  \frac{2}{3} miles per minute and

The speed of car in mile per hour is 40 miles per hour,

Step-by-step explanation:

Given as :

The distance cover by car = 2 \frac{1}{3} = \frac{7}{3} miles

The Time taken by car to cover distance =  3 \frac{1}{2} min =  \frac{7}{2} min

The speed o car in miles per minute = S miles/min

So, Speed = \dfrac{\textrm Distance}{\textrm Time}

Or, S = \frac{\frac{7}{3}}{\frac{7}{2}} mie per min

∴  S = \frac{2}{3} miles per minute

Now, Let The speed of car in miles per hour = x miles/h

So, Time in hour = \frac{7}{2} × \frac{1}{60} = \frac{7}{120} hours

So ,  Speed = \dfrac{\textrm Distance}{\textrm Time}

Or, x = \frac{\frac{7}{3}}{\frac{7}{120}} miles per hours

Or, x = 40 miles per hours

Hence The speed of car in miles per minute is  \frac{2}{3} miles per minute and the speed of car in mile per hour is 40 miles per hour, answer

What is the volume of a cone with a height of 9.5 inches and a radius of 8 inches? Cone V = 1 3 Bh 1. Rewrite the formula for th
Nesterboy [21]

Answer:

636.4 in³  

Step-by-step explanation:

Volume of a cone is given by:

V = \frac{1}{3}\pi r^2 h

where r is the radius of the base of the cone and h is its height.

It is given that, the radius of the base of the cone is, r = 8 in

The height of the cone is, h = 9.5

\Rightarrow V = \frac{1}{3} \times 3.14 \times (8)^2 (9.5) = 636.4 in^3

Thus, the volume of the cone is 636.4 in³

If the graph of the equation y=(x+2)^2 is reflected with respect to the y-axis, what is the equation of the resulting graph?
alexandr1967 [171]

Answer:

Is important to remember that the reflection of the point (a,b) across  the y-axis is the point (-a,b).

Our original equation is y= (x+2)^2

And after the reflection respect x we got:

y= (-x+2)^2

Step-by-step explanation:

Is important to remember that the reflection of the point (a,b) across  the y-axis is the point (-a,b).

Our original equation is y= (x+2)^2

And after the reflection respect x we got:

y= (-x+2)^2
