Answer:

68.75

Step-by-step explanation:

Measure the length of the parallel sides and add them together. Then multiply this number by the height of the area. Then multiply by ½ or divide by two to find the square footage of the trapezoid.

13.6 + 5.9= 19.5

19.5 + 8 = 27.5

27.5 x 5 = 137.5

137.5 x 1/2 = 68.75

BlackZzzverrR [31]

Before we begin, let's cross out "the small wheel could have an 18 inch diameter". This is useless information and should be disregarded to avoid confusion. Lots of questions include extraneous information to make you second guess yourself, so it is important to be aware of what the question is asking you and what you need in order to answer it.

The formula for circumference is $\pi$ x diameter. With this formula, we can substitute the value of the diameter, 52, into the equation.

Circumference = 3.14 x 52
Circumference = 163.28

Final Answer: the circumference of the big wheel is 163.28 inches

Are the following lines parallel perpendicular or neither y=-5/3x - 5 and y=4/3x - 5

katrin [286]

Answer:

neither

Step-by-step explanation:

For lines to be parallels the slopes must be equal, for the lines to be perpendicular the lines have to be inverse reciprocals meaning if you have a slope of 1/2X then the perpendicular line must be -2X

Is -100 rational or irational

pychu [463]

-100 is rational.

-100 can be turned into a fraction by doing the following...

Just put 1 underneath -100 and you get $\frac{-100}{1}$

So that means it is rational since it can be a fraction!

Goryan [66]

Answer:

30%
Unlikely

Step-by-step explanation:

The balls - multiples of 3 are:

3, 6 and 9

The probability of a multiple of 3 is:

3 out of 10 or
P = 3/10 = 30%

30% probability is in the range 0%-50% so this event is unlikely
