A gardener planted flowers of different colors.
3/10 of the flowers are yellow.
3/4 of the remaining flowers are green.
The rest are purple.
The gardener planted 119 purple flowers, how many flowers did the gardener plant?
Answers
Answer:
The gardener planted 680 flowers
Step-by-step explanation:
The different colors of flowers planted by the gardener are;
The proportion of the flowers planted that are yellow = 3/10
The proportion of the remaining flowers planted that are green = 3/4
The color of the rest of the flower planted = Purple
The number of purple flowers planted = 119 purple flowers
Let the number of flowers the gardener planted = x
Therefore, the number of yellow flowers planted = 3/10 × x
The number of green flowers planted = 3/4 × (x - 3/10 × x) = 21/40×x
The number of the rest of the flower which are purple = x - (3/10 × x+ 21/40×x) = x - 33/40×x = 7/40×x
∴ The number of the purple flowers planted = 7/40×x = 119
x = 119 × 40/7 = 680
The number of flowers the gardener planted = x = 680 flowers
The gardener planted 680 flowers.

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
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 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
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

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

If 2 pretzel makers can make 444 pretzels in 6 hours, how long does it take 5 pretzel makers to make 88 pretzels? Plz help me What is the answer to this equation?
Answers
Answer: Tt will take approximately 19.03 minutes.
Step-by-step explanation:
Formula required: [tex]\dfrac{M_1T_1}{W_1}=\dfrac{M_2T_2}{W_2}[/tex], where [tex]M_1[/tex] = number of men, [tex]T_1[/tex] = time taken,[tex]W_1[/tex] = work in situation 1, and [tex]M_2[/tex] = number of men, [tex]T_2[/tex] = time taken, [tex]W_2[/tex] = work in situation 2.
Given: If 2 pretzel makers can make 444 pretzels in 6 hours.
i.e. [tex]M_1=2,\ W_1=444, T_1=6\ hours[/tex]
To find : [tex]T_2[/tex] for [tex]M_25, W_2=88[/tex]
Substitute all value sin formula , we get
[tex]\dfrac{2\times6}{444}=\dfrac{5\times T_2}{88}\\\\\Rightarrow T_2=\dfrac{8\times88}{444\times5}=0.3171\ hour[/tex]
[tex]=0.3171\times 60= 19.026\text{ minutes}\ \ \ \ [\text{1 hour = 60minutes}][/tex]
hence, it will take approximately 19.03 minutes.
