Answer:
A
Step-by-step explanation:
A just cause
It looks like the given equation is
234₅ + 434₅ + x₅ = 2304₅
First, we have
234₅ + 434₅ = 1223₅
because
• 4₅ + 4₅ = (8)₅ = (5 + 3)₅ = 10₅ + 3₅ = 1<u>3</u>₅
(carry the 1)
• 3₅ + 3₅ + 1₅ = (7)₅ = (5 + 2)₅ = 10₅ + 2₅ = 1<u>2</u>₅
(carry the 1)
• 2₅ + 4₅ + 1₅ = (7)₅ = (5 + 2)₅ + 10₅ + 2₅ = <u>12</u>₅
Then x₅ = 2304₅ - 1223₅. We have
• 4₅ - 3₅ = <u>1</u>₅
0₅ - 2₅ is negative, so we borrow a 1 from the next digits place,
• 10₅ - 2₅ = (5)₅ - 2₅ = <u>3</u>₅
• (3 - 1)₅ - 2₅ = 2₅ - 2₅ = <u>0</u>₅
• 2₅ - 1₅ = <u>1</u>₅
x₅ = 2304₅ - 1223₅ = 1031₅
A number denoting quantity (one,two,three,etc) as opposed to a ordinal number ( first,second,third,etc)
Answer:
402 in^3
Step-by-step explanation:
We know that the volume of a sphere = 4
/3 πr^3
Variables:
r = 2in
Solve for 1 toy:
4
/3 πr^3
4/3 π (2in)^3
= 33.51 cubic inches for 1 toy
For 12 toys:
33.51 in^3 * 12 toys = 402.12 in^3 of water for all the toys
Round:
402.12 in^3 ≈ 402 in^3 of water
