Answer:
d = 
Step-by-step explanation:
Given
C = 3.14d ( isolate d by dividing both sides by 3.14 )
= d
Probability of choosing pink balloon is
.
Step-by-step explanation:
Given,
Number of green balloons = 5
Number of yellow balloons = 3
Number of red balloons = 4
Number of pink balloons = 8
Total number of balloons = 5+3+4+8 = 20
To find the probability of pink balloon.
Formula
Probability of an even = number of outcomes ÷ total number of outcomes
So,
Probability of choosing pink balloon =
= 
a= 16x+16
b= 40x + 15
Step-by-step explanation:
We know that perimeter of a rectangle is

So therefore



Answer= A) that is perimeter is 16x+16
We know that area of a rectangle is l×b
So therefore


Answer = b) that is area is 40x + 15
Answer:
15
Step-by-step explanation:
The 30-60-90 triangle rule is 2x-x-3(square root of x). Hope this helps.
6x(-3)= (-5x) + 7
-18x = -5x + 7
-18x + 5x = 7
-13x = 7
x = 7/-13
x= -7/13
