The number of workers that drink at least one of coca-cola and fanta is = 30.
<h3>Calculation using Venn diagram </h3>
The total number of workers under survey = 200
The number of workers that drink only coca cola = 130 - X
The number of workers that drink fanta = 100 - X
The number of workers that drank at least one drink = X
To calculate for x;
130 - X + X + 100 - X = 200
Being like terms together,
-X = 200 - 130 -100
-X = 200 - 230
-X = - 30
X = 30
Therefore, the number of workers that drink at least one of coca-cola and fanta is = 30

Answer:
x = 30°
y = 5
Step-by-step explanation:
The ∆ where you find x is an isosceles ∆ because two of its sides has a length of 40 each, since the other triangle has equal angles of 60° each, it also has equal length sides of 40.
Therefore, x is a base triangle of the isosceles, thus:
x = ½(180 - (180 - 60))
x = ½(180 - 120)
x = ½(60)
x = 30°
Let's find y.
8y = 40 (sides of an equilateral ∆ are equal)
Divide both sides by 8
y = 5

If 11 bubbles form in 30 seconds then in in 60 seconds double the amount of doubles. So 22 bubbles a minute. Glad to help.
Answer:
angle BED = 82
Step-by-step explanation:
angle BDE is equal to angle DBE because the opposite side are equal (both are radii)
angle BED = 180-49-49 = 82
