Ishaan is 3 times as old as Christopher and is also 14 years older than Christopher.how old is ishann?
Answers
Explanation:
Let's first assume few variables!
x = Ishann's age (in years)
y = Christopher's age (in years)
1. Ishann is 3 times as old as Christopher can be represented mathematically as:
x = 3y ---- (1)
2. Ishann is 14 years older than Christopher can be represented mathematically as:
x = y + 14 ---- (2)
Get the value of y from Equation (1) and plug it in Equation (2):
(2) => x = (x/3) + 14
3x = x + 42
2x = 42
x = 21
Hence Ishann is 21 years old!

V = 392 pi in^3 or approximately 1230.88 in^3
Step-by-step explanation:
The volume of a can, which is a cylinder, is given by
V = pi r^2 h
= pi (7)^2 * 8
= pi *392
We can approximate pi by 3.14
V = 392 * 3.14
=1230.88 in^3

Answer: 78. 571 unit²
Step-by-step explanation:
To find the area of a circle, we simple use the formular;
area of a circle = Πr²
The value of π = 22/7
r= radius of the circle = 5
area of a circle = Πr²
= 22/7 × 5 ×5
=550 / 7
= 78. 57143
=78. 571 unit² to the nearest hundredth
Therefore area of the circle with radius 5cm is 78. 571 unit²

3 and 1/2=6/2+1/2=7/2 feet
convert to inches
7/2 times 12=84/2=42 inches
k so
total space used=number of books times space each book uses
total space possible=42
space each book uses=5/8
so
42=numberofbooks times 5/8
multiply both sides by 8/5 to clera fraction (5/8 times 8/5=40/40=1)
336/5=number of books
67.2=number of books
since you cannot fit 0.2 book (besides being useless or very small), we round down
67 books
