A = base side=3

b= base side=5

c = base side=3

h= height=7-4=3

l= lenght=6

w= width=5

h= height=4

V= 1/4h√(-a⁴+2(ab)²+2(ac)²-b⁴+2(bc)²-c⁴) + l w h 

V=12.44+ 120=132.44 unit³

They all have to have common denominators

The common denominator is 32

3/4= multiply by 8/8= 23/32

3/16= multiply by 2/2= 6/32

11/32. Is. 11/32

1/8 multiply by 4/4 =. 4/32

Smallest to greatest is 1/8. 3/16. 11/32. 3/4

What is the result when 1/8x - 2 5/7 is subtracted from 3 1/4x + 7 1/14
g100num [7]
Let's break it down:
We need an LCM, a least common multiple, so it's easier to subtract
3 1/4x + 7 1/14
-
1/8x - 2 5/7

3 1/4 is equivalent to 3 2/8     
2 5/7 is equivalent to 2 10/14

3 2/8x + 7 1/14        or you can break it down to two parts also
-                               3 2/8x - 1/8x = 2 1/8x
1/8x - 2 10/14          7 1/14 - (-2 10/14) = 9 11/14
------------------           - - = +
2 1/8x + 9 11/14

The inverse variation equation shows the relationship between wavelength in meters, x, and frequency, y
Cerrena [4.2K]

We have been given that the inverse variation y=\frac{3\times 10^8}{x} shows the relationship between wavelength in meters, x, and frequency, y. We are asked to find the wavelength for radio waves with frequency 3\times 10^9.

To find the required wavelength, we substitute y=3\times 10^9 in our given equation and solve for x as:

3\times 10^9=\frac{3\times 10^8}{x}

x=\frac{3\times 10^8}{3\times 10^9}

We can see that both numerator and denominator has 3, so we can cancel it out.

x=\frac{1\times 10^8}{1\times 10^9}

Using quotient rule of exponents \frac{a^m}{a^n}=a^{m-n}, we will get:

x=1\times 10^{8-9}

x=1\times 10^{-1}

Therefore, the wavelength for radio waves would be 1\times 10^{-1} meters and option B is the correct choice.
