Answer:
A intersection B = ( elements which are common in both)
= ( 2,4,7,19)
A union B = ( all the elements which are either in A or in B).
= ( 2, 4, 7 , 13, 14, 19, 20 , 3, 5, 6, 10,11, 12 , 15,17 , 18 , 19 )
6 and 3000 is the answer for ur question would be 3000
Answer:
5.45 hours.
Step-by-step explanation:
The formula =
P = P0(10)t
In this circumstance, P0 = 275, P = 15,000 and t = ?
Applying the values into the formula:
P = P0(10)t
15,000 = 275 × (10) × t
15,000 = 2750t
t = 15,000/2750
t = 5.45 hours
Answer:
600 m³
Step-by-step explanation:
Given:
- length of swimming pool = 30 m
- width of swimming pool = 10 m
- depth at deep end = 3 m
- depth at shallow end = 1 m
To find the volume of the water in the pool, find the area of a cross section (see attached image) and multiply it by the width of the pool.
<u>Area of cross section</u>
= area of rectangle - area of triangle
= (3 × 30) - [1/2 × 30 × (3 - 1)]
= 90 - 30
= 60 m²
<u>Volume of pool</u>
= area of cross section × width
= 60 × 10
= 600 m³
