Answer:
If he spins a spinner with 5 equal sections they have equally likely probability of 20%
If he rolls a fair die in the shape of pyramid with 4 sides each side has probability of 25%
If he rolls a fair die in the shape of cube with 6 sides each side has probability of 16.7
Total number of outcomes = 5 * 6 * 4 = 120
Answer:
20%
Step-by-step explanation:
Well, it's actually relatively simple.
The first thing to do would be to write this in a fraction form. You payed 72,000 out of 360,000.
72,000/360,000.
now you take that fraction, and convert it's to its decimal form which will give you a 0.2.
0.2 in decimal form is converted to 20.0% (when you convert a decimal to a fraction, you multiply by 100, or move the decimal two places to the right).
Another way to do this is simplifying the fraction.
take 72,000/360,000 and find what X is when
72,000/360,000 = x/100
you will find that 72,000/360,000 Is equal to 20/100. since percents are calculated as out of a hundred. your answer would still come out as 20%
5X+yb=zmh
5x+yb-yb=zmh-yb
5x=zmh-yb
5x/5=zmh/5-yb/5
x=mhz-by/5
To solve this, we work out the perimeter of the hexagon, by finding x, and we work out the perimeter of the pentagon by find y, and the compare them:
Perimeter of the Hexagon:
Since it is a regular hexagon, all the sides are the same: This means we can say that:
4x - 2 = x + 4 (Now lets solve this)
4x = x + 6 ( Add both sides by 2 to get 4x alone)
3x = 6 (Subtract both sides by x, to collect the x values)
x = 2 (Divide both sides by 3 to get what just x is)
Now we work out the length of one side by substituting the value for x in
x + 4 = 2 + 4
= 6
Now that we know the length of one side, we can multiply that by 6 to get the perimeter, because a hexagon has six sides.
6 * 6 = 36
Perimeter of the Pentagon
Since it is a regular Pentagon, all the sides are the same, just like the hexagon. This means we can say that:
5y - 8 = 2y + 1 (Now we solve this like we did before)
5y = 2y + 9 ( Add both sides by 8 to get 5y alone)
3y = 9 (Subtract both sides by 2y, to collect the y values)
y = 3 (Divide both sides by 3 to get what just y is)
Now we work out the length of one side by substituting the value for x in
2y + 1 = (2 * 3) + 1
= 7
Now that we know the length of one side, we can multiply that by 5 to get the perimeter, because a pentagon has 5 sides.
5 * 7 = 35
Since the perimeter of the hexagon is 36, and the perimeter of the pentagon is 35, we can see that:
The hexagon has the larger perimeter.
