If a man runs for an hour and a half at 8 miles an hour due south; and then he continues south on a bus traveling at 55 miles an

Usimov [2.4K]

He ran 8 miles per hour.

Multiply his speed by the time he ran to find total distance:

8 mph x 1.5 hours = 12 miles

He ran for 12 miles.

Now Find the distance the bus went:

For time, divide the minutes the bus drove by 60 minutes per hour.

55 miles per hour x 24/60 = 22 miles

The bus went 22 miles.

Total distance = 12 + 22 = 34 miles.

Explain why it makes sense for this situation to have a linear equation

IgorC [24]

Answer:

The line of best fit for your specific question is a linear equation.

Step-by-step explanation:

A linear equation has a constant rate of growth/decline and the growth/decline rate will never change in an linear equation.

If you draw a line that approximately splits between all the data plots, you will notice the line you drew is very close to the data points.

If the data plots was a quadratic, it would be very hard to draw a line of best fit.

Linear equations can easily be identified in a graph because it is a straight line.

Perhaps insert this equation into your graphing calculator or other graphing software online (like Desmos): y = 3x+2

A quadratic equation can also easily be identified in a graph because, in most cases, it looks like a U.

Take these examples: y = $3x^2+5x+2$ or y= $-2x^2+10x+30$

CLASS 6 MATHS!!!! HELP ME PLEASE!!!!!!!

Elanso [62]

Step-by-step explanation:

$\\ 20. \: \: ( \frac{ - 3}{4} )(4\frac{1}{6} )$

$\\ = \frac{ - 3}{4} \times \frac{25}{6}$

$\\ = \frac{ - 25}{8}$

$\\ = - 3.125$

$\\ 21. \: \: ( - 3\frac{7}{8} )( - 5\frac{3}{4} )$

$\\ = \frac{ - 31}{8} \times \frac{ - 23}{4}$

$\\ = \frac{713}{32}$

$\\ = 22.28125$
