Ametal cup full of water has a mass of 1,000 g. the cup itself has a mass of 214.6 g. if the cup has both a diameter and a height of 10 cm, what is the approximate density of water?

Approximate density of water is 1 g/cm³.

Step-by-step explanation:

Since we have given that

Mass of metal cup full of water = 1000 g

Mass of cup = 214.6 g

So, Mass of water = Mass of filled cup - Mass of empty cup

Mass of water = 1000 g - 214.6 g

Mass of water = 785.4 g

Diameter of cup = 10 cm

Radius of cup = 5 cm

Height of cup = 10 cm

So, volume of cup is given by

so, Density of water would be

Hence, approximate density of water is 1 g/cm³.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
