The area which is not in used for the flower gardens is 10964 sq ft.
Step-by-step explanation:
Given,
Length (l) of the rectangular park = 160 ft
Width (b) of the rectangular park = 80 ft
Length (l) of each rectangular flower garden = 18 ft
Width (b) of each rectangular flower garden = 17 ft
To find the area which is not in used.
Formula
The area of rectangle = l×b
Now,
The area of the rectangular park = 160×80 sq ft = 12800 sq ft
The area of each rectangular flower garden = 18×17 sq ft = 306 sq ft
The area of 6 rectangular flower garden = 306×6 sq ft = 1836 sq ft
So,
The area which is not in used = 12800-1836 sq ft = 10964 sq ft.
to be sure that 2 of them will be blue i have to select 7+2=9 balls
7+8=15 balls in the urn
P=9/15
to be sure that 4 of them will be yellow i have to select 8+4=12 balls
P=12/15
Answer:
True: 5, 15, and 10
Step-by-step explanation:
6*5=30 Correct, 30 is less than 100
6*15=90 Correct, 90 is less than 100
6*10=60 Correct, 60 is less than 100
6*20=120 Wrong, 120 is greater than 100
Writing it in the form of a+bi we get 0+4i
Step-by-step explanation:
We need to evaluate expression -16 squared and write the result in form a+bi
The given expression is: 
We know that 
We know that 16= 4x4 = 4^2
Putting values:
So, Writing it in the form of a+bi a=0 and b=4 so, 0+4i
