Answer:
1 pi: 3pi
Step-by-step explanation:
Step 1: Formula of surface area and volume of sphere
Surface area of sphere = 4 x pi x r^2
Volume of sphere = <u>4</u> x pi x r^3
3
Step 2: Apply values in the formula
r = radius
radius = diameter/2
r=18/2 = 9
S.A = 4 x pi x 9^2
S.A = 324pi
Volume = <u>4</u> x pi x 9^3
3
Volume = 972pi
Step 3 : Show in ratio
Surface area : Volume
324pi : 972pi
= 1 pi: 3pi
Y=6x-27...........(1)
y=4x-17...........(2)
By comparison
6x-27=4x-17
=> 2x=10 => x=5
Substitute x=5 into (1)
y=6(5)-27=3
Check:
y=4(5)-17=3 as well.
Answer:
- <u><em>31 animals</em></u>
Explanation:
The question is in French language. The translation to English is:
<em>1 rabbit saw 6 elephants while going to the river. Each elephant saw 2 monkeys go towards the river. Each monkey holds 1 parrot in its hands.</em>
<em>How many animals are going to the river?</em>
<em />
<h2>Solution</h2>
<em />
Animal amount
Rabbit 1
Elephants 6 (the rabbit saw 6 elephants)
Monkeys: 6 × 2 = 12 (2 monkeys per elephant)
Parrots: 12 × 1 = 12 (1 parrot per monkey)
=============================
Total: 1 + 6 + 12 + 12 = 31 animals ← answer
This problem is easy the correct choice for it will be B.
She will have to pay $5,704 in social security taxes.
-In order to find 6.2% of 92,000 you have to multiply .062 * 92,000. This will get you $5,704.
