Answer:
b) 4.5 hours
Step-by-step explanation:
The first cyclist has a 3-hour head start. At 6 mph, that is an 18-mile head start.
The second cyclist gains on the first at the rate of (10 -6) = 4 mph, so will make up that 18 miles in ...
(18 mi)/(4 mi/h) = 4.5 h
The second cyclist will catch up with the first after 4.5 hours from the time the second cyclist started.

Answer:
x + 6
Step-by-step explanation:
From the question given above, the following data were obtained:
Length of rectangle = 3x + 6
Width of rectangle = 4x – 1
Width of door =..?
A careful observation of the diagram shows that the door is located along the length of rectangular room.
In a rectangle, two sides are equal. Therefore,
x + door + x = 3x + 6
Making door subject of the above formula, we have:
x + door + x = 3x + 6
door + x + x = 3x + 6
door + 2x = 3x + 6
Subtract 2x from both side
door + 2x – 2x = 3x + 6 – 2x
door = 3x – 2x + 6
door = x + 6
Therefore, the width of the door is x + 6

Answer:
2.25
Step-by-step explanation:
The number 2.25 is already in standard form.
___
In the US (and other places), "standard form" is an ordinary decimal number, with the integer part to the left of the decimal point and the fractional part to the right of the decimal point: 2.25.
In the UK (and other places), "standard form" is a number written in scientific notation with a mantissa consisting of the leading non-zero digit to the left of the decimal point, the remaining significant digits to the right of the decimal point, and a multiplier that is 10 to the power appropriate to the place value of the leading digit. When the multiplier is 1, we need not write it.
2.25 = 2.25×10⁰ (full form) = 2.25 (with superfluous 10⁰ removed)
