1 3/4 + 3 3/8
get a common denominator by multiplying 1 3/4 by 2 to get a denominator of 8
1 3/4 becomes 1 6/8
1 6/8 + 3 3/8 = 5 1/8 yards
so the answer is
C. 5 1 / 8 Yards
Answer:
I got the third one DC=56
Step-by-step explanation:
Answer:
24 quarters
Step-by-step explanation:
step 1
Find out the total cost
Multiply the total hours by the unit rate of $2.00 per hour
so
step 2
To find out how many quarters Ben needs, divide the total cost by $0.25 (value of one quarter coin)
so
5/8 or .625 is the answer
Let's assume the frequency of sound be f and wave length is w.
Given that, the frequency of sound varies inversely as the wavelength.
So, we can set up an equation as following:
f*w = k Where k= constant of variation.
Other information is, the frequency of a musical note is 276 cycles per second when the wavelength is 1.2m.
So, next step is to plug in f = 276 and w = 1.2 in the above equation to get the value of k.
276 * 1.2 = k
So, k = 331.2
Next step is to plug in k = 331.2 in the above equation. So,
f * w = 331.2
Now we need to find the wave length : w when frequency : f = 600.
Therefore,
600 * w = 331.2
w = \frac{331.2}{600}
So, w = 0.552
Hence, the wave length is 0.552 m.
Hope this helps you!.
