The factors of 65 are 1, 5, 13, and 65 .

The factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70 .

Factors of a number are those numbers which divide a number without leaving any remainder
The factors of 65 are 1,5, 13,65 because all of these can divide 65 without leaving any remainder
The factors of 70 are 1,2,5,7,10,14,35,70 since all of them can divide 70 without leaving any remainder
The factors of 100 are 1,2,4,5,10,20,25,50,100 since all these can divide 100 without leaving any remaider

A landscaper is selecting two trees to plant. He has five to choose from. Three of the five are deciduous and two are evergreen.What is the probability that he chooses trees of two different types? Express your answer as a percent.

Answers

The probability that he chooses trees of two different types is 0.6 or 60%.

What is probability?

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

We have a landscaper who is selecting two trees to plant.

The total number of trees he has = 5

Total ways of choosing the two trees = $_(5)^{}\textrm{C}_2$

$=(5!)/(2!(5-2)!)$

= 10

Total ways of choosing one of each = $_(3)^{}\textrm{C}_1*_(2)^{}\textrm{C}_1$

= 6

So probability:

= $(6)/(10)$

= 0.6 or 60%

Thus, the probability that he chooses trees of two different types is 0.6 or 60%.

Total ways of choosing two trees = 5C2 = 5!/(2! 3!) = 10

Total ways of choosing one of each = 2*3 = 6

Probability = 6/10 = 0.6 = 60%

If x=5 and the area of the rectangle is 30 what is the other length of the rectangle?

Answers

Answer:

The other length would be 6.

Step-by-step explanation:

Rectangle area is l times height. So x is either the length for height. So we have 5 times x = 30. To find the other length we have to take 30/5 which equals 6
