If 80° ------> 88π cm
Then 360° ------> x cm
So:
x = (88π x 360) ÷ 80
x = 396 π (lenght of the circle)
The relationship of Lenght of circle and its diameter is:
L = d .π
replacing L:
396 π = d.π ----> d = 396 cm <---- here is your answer
Answer:
The slope is 4/3
Step-by-step explanation:
Slope is found by using the equation
m = (y2-y1)/(x2-x1)
where (x1,y1) and (x2,y2) are two points
m=(1--3)/(1--2)
= (1+3)/(1+2)
= 4/3
$30 is 60% of $50.
100 % is the whole figure. Based on the problem, 100 % is separated into two parts, 60% and 40%
100% = 60% + 40%
To get the number where $30 is 60%. Let X be the 100% number.
First, divide all number by 100% to remove the percentage and get the whole number.
100%X = 30 + 40%X
X = 30 + 0.40X
X - 0.40X = 30
0.60X = 30
To get X, divide both sides by 0.60
X = 30 / 0.60
X = 50
To check: Substitute all X by 50.
X = 30 + 0.40X
50 = 30 + (0.40*50)
50 = 30 + 20
50 = 50 EQUAL. CORRECT.
Answer:
the answer is 31 that the costumers regularly buy that's why it left 20
