MrRissso [65]

Answer:

The bus will travel 720 miles in 15 hours.

Step-by-step explanation:

As you know that the bus traveled 336 miles in 7 hours and it traveled the same number miles each hour, you can divide the amount of miles it traveled by the number of hours to determine the amount of miles per hour:

336/7=48

Now, you can multiply the number of miles the bus traveled each hour for 15 hours:

48*15=720

According to this, the answer is that the bus will travel 720 miles in 15 hours.

A rug is to fit in a room so that a border of consistent width is left on all four sides. If the room is 15 ft by 25 ft and the
AlladinOne [14]

Answer: Option 'a' is correct.

Step-by-step explanation:

Since we have given that

Dimensions of the room is given by

15 ft by 25 ft

Let x be the width around the rug.

So, new length = 15-2x

new breadth = 25-2x

Since Area of the rug = 264 sq. ft

So, it becomes,

\text{Area of rug}=Length\times breadth\\\\264=(15-2x)(25-2x)\\\\264=375-30x-50x+4x^2\\\\264=375-80x+4x^2\\\\4x^2-80x+375-264=0\\\\4x^2-80x+111=0\\\\x=\dfrac{3}{2}\ or\ x=\dfrac{37}{2}\\\\x=1.5\ ft

Hence, Option 'a' is correct.
