The inverse variation equation shows the relationship between wavelength in meters, x, and frequency, y.
Vaselesa [24]

<u>Answer:</u> The wavelength for X-rays with the given frequency is 1\times 10^{-10}m

<u>Step-by-step explanation:</u>

To calculate the wavelength of light, we use the equation:

\lambda=\frac{c}{\nu}

where,

\lambda = wavelength of the light  

c = speed of light = 3\times 10^8m/s

\nu = frequency of light = 3\times 10^{18}s^{-1}

Putting the values in above equation, we get:

\lambda=\frac{3\times 10^8m/s}{3\times 10^{19}s^{-1}}=1\times 10^{-10}m

Hence, the wavelength for X-rays with the given frequency is 1\times 10^{-10}m

Sarah bought 3 1/2 pints of blueberries to make jelly. She ate 3/4 of a pint of berries on her way home. How many pints of berri
AnnyKZ [126]

Answer:

11/4 or 2.75 pints

Step-by-step explanation:

We want to find the difference between the original amount of blueberries and the amount she ate

original amount-amount ate

3 1/2 -3/4

To subtract, we need common denominators

The common denominator of 2 and 4 is 4

3 1/2=7/2

Multiply by 2/2 to get a common denominator of 4

7/2*2/2=14/4

Now, we have common denominators and can subtract

14/4-3/4

Subtract the numerators, and leave the denominators as 4

11/4 =2.75

She has 11/4 or 2.75 pints left
