Answer:
25 and there a leftpover of 2
Step-by-step explanation:
2L = 2000mL
2000mL / 400mL = 5
therefore, each cup is filled exactly half way
There is 200mL in each of the 10 cups.
Answer: 3234 cubic units
Step-by-step explanation:
Volume of cylinder: πr²h
The diameter of the cylinder is 14 units so the radius is 7 units.
Now we'll substitute.
π = 22/7
h = 21
πr²h
π × 7² × 21
22/7 × 49 × 21 = 3,234
The volume is 3,234 cubic units.
Answer:
31 years to triple the investment
Step-by-step explanation:
Initial investment = 300
Triple amount that is final amount = 300*3= 900
rate of interest = 3.5 % = 0.035
we need to find out number of years (t)
for compounded continuously we use formula

A is the final amount
P is the initial amount
r is the rate of interest
t is the number of years

Divide both sides by 300

take 'ln' on both sides

ln(3) = 0.035t ln(e)
ln(e)= 1

t= 31.3889
Round to nearest whole number
t= 31 years
1) 543/1000
2) 54.3
You're welcome ;)
