Answer:
(35k + 20) cents
Step-by-step explanation:
First of all, let us have the value of each unit:
1 quarter = 25 cents
1 nickel = 5 cents
1 dime = 10 cents
Given that number of quarter = k
Quarters are 5 lesser than Nickels, so number of nickels = k+5
One more than twice as many dimes as quarters:
k = 2
Number of Dimes + 1
So, number of dimes = 
Value of quarters =
cents
Value of nickels = 
Value of dimes = 
So, total value of coins =

Firstly,
thanks for posting this.
81 = 9x9 or 9 squared so at this stage I'm guessing the last two.
x^ 8 = (x^ 4) x (x^ 2) (its called the multiplication rule of indices).
Okay I have approx 14 mins to answer.
No panic
√ 81.x^8 x <span>√ y^5
</span>√ (9x^2 x 9x^6) x <span>√ y^5
</span>= 9x x <span>√ 9x^6 x </span><span>√ y^5
</span>did I just gain time?
√ 9x^6 = <span>√ </span>3x ^3 x <span>√ 3x ^ 3
</span>or 2 . √ 3x^3. <span>√ y^5
</span>more time
okay, so that wasnt successful.
√ 9x^6 =<span>√ </span> (3x^2) x <span>√ </span>(3x^4)
P(n)=news time/total time
We are told that the news is 14 minutes long during an hour so
p(n)=14/60
p(n)=7/30

Answer:
see the explanation
Step-by-step explanation:
The given rate is

Create three different rates, that are all equivalent to this rate
<u>First rate </u>
1,440 gallons in 3 hours
Find the units rate
Divide the total volume by the total time

<u>Second rate </u>
960 gallons in 120 minutes
Find the units rate
Divide the total volume by the total time
Convert minutes to hours


<u>Third rate </u>
720 gallons in 1.5 hours
Find the units rate
Divide the total volume by the total time

<em>Convert gal/h to gal/min</em>
Remember that
