Answer:
Step-by-step explanation:
c+7
you have 7 more then a number c
Exponential growth has the form:
F=Ir^t, F=final amount, I=initial amount, r=rate, t=time.
First let's solve for the rate, r, using the points provided...
37325/34560=(Ir^2)/(Ir^1)
r≈1.08
Now find the initial amount...
34560=I(1.08)^1
I=32000 so now we have the entire equation, using x and y...
y=32000(1.08)^x
Answer:
27 weeks.
Step-by-step explanation:
You need to calculate the minimun common multiple between the three times.
1 week = 1^1 week
9 weeks = 3^2 weeks
27 weeks = 3^3 weeks
You take the 1 and the 3 with the biggest exponent and multiply. In this case is 1^1*3^3 = 27. So, in 27 weeks the pkanets will all be in alignment.
X = 3.916

Answer:
62.5 : 37.5
Step-by-step explanation:
When we divide 100 into 5:3 ratio the parts we make need to add up to 100
5parts +3 parts = 8 parts
100/8 parts = 12.5 are in each part
12.5*5 : 12.5*3
62.5 : 37.5
check our answer 62.5+37.5 = 100 ✅
