The length of a rectangle is
four times its width. If the
area is 100 meters squared,
what is the length of the
rectangle?

Answers

Answer:

5 is the width 20 is the length

Step-by-step explanation:

5*4= 20 and 20*5=100

We know that the area of any rectangle is length times width. The perimeter is the sum of twice the length and twice the width.

Let width = x
Let length = 4x
Area = 100m2


Next, we can write an equation using these variables and formula for area.

4x2 = 100

x2 = 25


x = -5 and x = 5

Since the dimensions cannot be negative, we accept the positive value:

x = 5


Next, we can substitute this value of x into the variables.

width = 5 m
length = 20 m


Finally, we can find the perimeter by plugging in these dimensions into the perimeter formula,

Perimeter = 2(5 m) + 2(20 m)
= 10 m + 40 m
= 50 m

In a class 21 of students, 7 have a brother and 6 have a sister. There are 4 students who have a brother and a sister. What is the probability that a student who has a brother also has a sister?

Answers

Let x be the number of students having both brother and sister.

Brother only is 7-x
Sister only is 6-x


Brother only + sister only + both + neither = 21
(7-x) + (6-x) + x + 4= 21
-4 - x = 21
x = 17

Per definition of conditional probability:
prob( brother | sister) = prob ( brother AND sister) / prob ( sister)
17/6 = 2 5/6
17/6 = 2 5/6 = 25%

The "Pick 3" at horse racetracks requires that a person select the winning horse for three consecutive races. If the first race has eleven entries, the second race nine entries, and the third race seven entries, how many different possible tickets might be purchased?

Answers

Answer:

693

Step-by-step explanation:

To find the number of possible tickets that would be purchased we simply multiply the total number of choices that each race provides together. This would tell us how many combinations exist which in term is the same as the different possible tickets that can be purchased. Since the choices for the first race are 11, the second race 9, and the third race 7, we multiply these numbers together...

11 * 9 * 7 = 693 possible tickets
