Answer:
The value of account after 8 years is $8580
Step-by-step explanation:
Given in question as :
The principal that invested in an account = $6,000
The annual interest rate compounded quarterly = 4.5%
Time period = 8 years
Now from compound Interest method for quarterly .
Amount = Principal 
Or,Amount = $6,000 
Or, Amount = $6,000 (1.430)
∴ Amount = $8580
Hence the value of account after 8 years is $8580 Answer
If we know that she got 75%, we can write it as the fraction 75/100.
We also know that she got 60 correct out of an unknown number of questions, which we can call 'x'
We means we know that 75/100 = 60/x (the number of questions)
Cross multiply to get an equation.
75 * x=60 * 100 -----> 75x=6000
Divide both sides by 75 to solve for x.
6000/75=80
x=80, meaning that her test had 80 questions on it.
Answer:
decreaseing
Step-by-step explanation:
-2 it goes down
Speed: distance traveled in a given time
y=distance ( given in miles).
x = time (given in minutes)
Speed = y/x
y = 39.4x
By rearranging this y/x =39.4 ( is the constant speed). don’t forget this is mile/minutes
There are 4 x 60 minutes in 4 hours
Hence, you are asked the distance (y) in 240 min
y = 39.4x
y = 39.4 miles/minutes x (240) minutes
y = 9456 miles
