Answer:
1) is x2=x=1950
2) x3=x=597
Step-by-step explanation:
39*100=3900
3900/2=1950 x2=x=1950
the next one is 9*199=1791
1791/3=597 x3=x=597
Answer: the height of the water after the sphere is placed in
it is 33.33 cm
Step-by-step explanation:
The cylinder is called a right circular cylinder because its height make a right angle with its base. The formula for determining the volume of the cylinder is expressed as
Volume = πr^2h
Where
π is a constant whose value is 3.14
r represents the radius of the cylinder.
h represents the height of the cylinder.
From the information given,
r = 10 cm
h = height of water in the cylinder = 20 cm
Volume of water in the cylinder before the sphere was placed in it would be
V = 3.14 × 10^2 × 20 = 6280 cm^3
The formula for determining the volume of the sphere is expressed as
Volume = 4/3 πr^3
V = 4/3 × 3.14 × 10^3 = 4186.67cm^3
Total volume of the sphere and the cylinder = 6280 + 4186.67 = 10466.67 cm^2
To determine the new height of the water,
10466.67 = 3.14 × 10^2× h
h = 10466.67/314 = 33.33 cm
Answer:
4 days
Step-by-step explanation:
Crickets team = every 2 days
Football team = every 4 days
How much days from now will they have to share the field again?
Find the lowest common multiple of 2 days and 4 days
2 days = 2, 4, 6, 8, 10, 12, 14, 16, 18, 20
4 days = 4, 8, 12, 16, 20
The lowest common multiple of 2 days and 4 days = 4 days
Therefore, if the football team and Crickets team share the field to practice today, they will have to share the field again in the next 4 days
