Answer:
Ben has 225 seashells
Step-by-step explanation:
<u>Step 1: Use the ratio to see how many times the amount Andy has</u>
4 * n = 100
4n / 4 = 100 / 4
<em>n = 25 times the amount of the ratio</em>
<em />
<u>Step 2: Find out how many shells Ben has</u>
Use the 25 times the ratio to help
9 * 25
225
Answer: Ben has 225 seashells
<u>Check: See if the ratio still works</u>
Andy = 100
Ben = 225
100 : 225
(100/25) : (225/25)
4 : 9 -> Correct, so the answer is good
A growth function has the following form.
where
= Original amount,
r = annual rate of change,
n = number of periods,
t = time in years
Since the time is in years, we need to convert t into days. We know that 1 year = 365 days. So t years = 365t days.
So in this case, n = 365, r = 0.0095.
Then the function is rewritten as follows.
The daily growth rate would be
Answer:
√2 x √2 = 2
Step-by-step explanation:
Square roots that aren't perfect squares are irrational.
For Ex: √2 is irrational.
But √2 x √2 = √4 = 2. 2 is rational
Ex. 2 : √8 x √2 = √16 = 4. 4 is rational
I’m guessing it’s D because it just stops on the y-axis and if it was symmetrical then it wouldn’t be a function at all
Answer:
R = 40
A= 1.125
Step-by-step explanation:
12(R) ÷1.5(A) =8
1.5(A) x 8 = 12(R)
1.5(A) x 8 = 12(R) 12(R) ÷ 8 = 1.5 (A)
for 1.5 = 12, you need to times 8
A = 5 and you want to get to R so you times by 8
5 x 8 = 40 | R = 40
R = 9
9 ÷ 8 = 1.125
A = 1.125
