Step-by-step explanation:
a)
we have 400 people. that is 10/10 of the whole group.
7/10 of the whole group drink tea. that is
400 × 7/10 = 40 × 7 = 280
that leaves 3/10 of the whole group not drinking tea
400 × 3/10 = 40 × 3 = 120
from the 280 tea drinkers 20% drink at lay e cups of tea each day. that is
280 × 20/100 = 28 × 2 = 56
because 20 out of 100 is the meaning of 20%.
and the remaining 80% of the tea drinkers drink less then 3 cups each day.
280 × 80/100 = 28 × 8 = 224
b)
out of the 400 people 56 drink at least 3 cups of tea each day. that is
56/400 = 7/50
Answer:
1,498,454,000 sq. miles
Step-by-step explanation:
Volume of a sphere = 4/3 (3.14) r^3
So since the diameter is 1420 miles, the radius would be half.
V = 4/3 x (3.14) x 710^3
V=4.18666667 x 357,911,000
V = 1,498,454,054.5 but if you want it rounded to the nearest thousand then it'd be 1,498,454,000.
