Your answer is 30 m/s.To find the wave speed multiply the frequency by the wavelength.
Step-by-step explanation:
3/4 x 1/4 x 3/4 = 0.140625
b. P(WCW)=0.140625
P(CWW)=0.140625
P(WWC)=0.140625
c. P(WCW) + P(CWW) + P(WWC)=0.421875
Answer:
proved.
Step-by-step explanation:
We have to prove that
So, the left hand side =
= {Since we have the formula }
= {Since we have the formula }
=
=
= {Since }
= Right hand side
Hence, proved.
Given : Kishore bought a basket containing 30 oranges for rs 310. If he sells the oranges at rs 12 each , what Would be it's profit or loss?
Solution :
Cost price of oranges = rs.310
As we know that each oranges cost rs.12
So, selling price of oranges is 30 × 12 = rs.360
Now, <u>finding profit or loss</u>
Profit = Selling Price - Cost Price
Profit = rs.360 - rs.310
Profit = rs.50
Answer:
- Total value in cents = 51p+5n
- Total value in dollars = (51p+5n)/100
The answer varies depending if your teacher wants the answer in cents only, or in dollars only.
====================================================
Explanation:
- p = number of pennies
- n = number of nickels
- 2p = number of quarters, since we have twice as many quarters compared to pennies.
Based on that, we know,
- p = number of cents from the pennies (1 penny = 1 cent)
- 5n = number of cents from the nickels (5 nickels = 5 cents, multiply both sides by n)
- 25(2p) = 50p = number of cents from the quarters
and ultimately
p+5n+50p = 51p+5n
represents the total value of all the coins, and this value is in cents. We would divide by 100 to convert from cents to dollars. So we can say that 51p+5n cents = (51p+5n)/100 dollars
----------------
As an example, let's say
So we have
- p = 4 pennies
- n = 5 nickels
- q = 2p = 2*4 = 8 quarters
This would mean we have
- p = 4 cents from the pennies only
- 5n = 5*5 = 25 cents from the nickels only
- 25q = 25*8 = 200 cents from the quarters only
Overall we have p+5n+25q = 4+25+200 = 229 cents which converts to 229/100 = $2.29
We can also say 51p+5n = 51*4+5*5 = 204+25 = 229 which is a slight shortcut to get the same result (that result being in cents).
