15 minutes because if you add 2/5 together 5 times you get 2 and you need 6 so 2+2+2=6 so you add 5+5+5=15 so your answer is 15.
Answer:
x = 18
Step-by-step explanation:
The scale factor between the two numerators are 1/2.
Scale factor
= numeratorANS / numeratorKNOWN
= 7/14
= 1/2
Multiply the denominator by the scale factor to find x.
x = 36 * 1/2
x = 18

The Second One I Think
Step-by-step explanation:
By what I understand that would be the one that is in standard form
Answer:
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1+r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = 4500
A = 6300
r = 6.75% = 6.75/100 = 0.0675
n = 2 because it was compounded 2 times in a year.
Therefore,.
6300 = 4500(1 + 0.0675/2)^2t
6300/4500 = (1 + 0.03375)^2t
1.4 = 1.03375^2t
Taking log of both sides of the equation, it becomes
Log 1.4 = 2t log 1.03375
0.1461 = 2t × 0.0144 = 0.0288t
t = 0.1461/0.0288
t = 5.1 years.
