Answer:

$155,520

Step-by-step explanation:

When the value rises 20%, it is 1.2 times what it was. This has occurred 3 times, so the value is now 1.2³ = 1.728 times what it was.

... $90,000 × 1.2³ = $155,520

Neil drives at an average speed of 60 miles/hour to reach
nikklg [1K]

Answer:

 480/(x+60) ≤ 7

Step-by-step explanation:

We can use the relations ...

 time = distance/speed

 distance = speed×time

 speed = distance/time

to write the required inequality any of several ways.

Since the problem is posed in terms of time (7 hours) and an increase in speed (x), we can write the time inequality as ...

 480/(60+x) ≤ 7

Multiplying this by the denominator gives us a distance inequality:

 7(60+x) ≥ 480 . . . . . . at his desired speed, Neil will go no less than 480 miles in 7 hours

Or, we can write an inequality for the increase in speed directly:

 480/7 -60 ≤ x . . . . . . x is at least the difference between the speed of 480 miles in 7 hours and the speed of 60 miles per hour

___

Any of the above inequalities will give the desired value of x.

Breanna has quarters, dimes, and nickels in her purse. she has 3 fewer nickles than dimes, but she has 2 more nickles than quart
zmey [24]
We base ourselves in the one piece of crucial evidence: She has 2 quarters.
-from the rest of the problem, we know that she has 2 more NICKEL'S than QUARTERS, 

(2 Quarters + 2 = 4 nickels)

she has 3 fewer nickels than dimes, 

DIME - 3 = Nickels

D - 3 = 4

D = 7

7 dimes
(70 cents)

4 nickels
(20 cents)

2 quarters
(25 cents)

115 cents
or $1.15
