A plane flew 193 km in 12 minutes. At a constant speed what was the speed of the air plane at km per hour?
Mrac [35]

Answer:

965  km per hour

Step-by-step explanation:

The total distance flown was 193km which was flown at  constant speed and took 12 minutes.  Dividing 193 by 12 gives us the km per minute

 193/12 = 16.0833333

but this isn't the correct answer, this is in km per minute, and the question asked for km per hour.  Since there are 60 minutes in an hour, multiply the answer by 60 to calculate how far the plane flew per hour.

16.083333333(60)  =  965

Find the x- and y-intercepts 3x+y=5
vlada-n [284]

The x - intercept is (\frac{5}{3}, 0) and y - intercept is (0, 5)

<h3><u>Solution:</u></h3>

Given that : 3x + y = 5

<em><u>To find: x - intercept and y -intercept</u></em>

The x-intercept is where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis.

To find the x intercept using the equation of the line, plug in 0 for the y variable and solve for x

3x + 0 = 5

3x = 5

x = \frac{5}{3}

Therefore the x - intercept is (\frac{5}{3}, 0)

To find the y intercept using the equation of the line, plug in 0 for the x variable and solve for y

3(0) + y = 5

y = 5

Therefore y - intercept is (0, 5)

24% of 289 estimated using<br> a rate per 100
zaharov [31]

Answer:

The answer would be 40!

Step-by-step explanation:

Estimating ~ rounding

I would round 24% (20%), and 289 (300).

using the formula:

is/of \\ = %/100,

I'm looking for "IS"

I multiply 20 (just 20, no percent) by 200 = 4000.

Then I divide by 100 to get the "IS".

That's how I got my answer!

Hope this helps!
