Evaluate 13 - 0.75w+8x when w=12 and x= 1 over 2

Zepler [3.9K]

Answer:

Step-by-step explanation:

Given:

13 - 0.75w + 8x

where,

w = 12

x = 1/2

13 - 0.75w + 8x

Substitute the value of w and x into the equation

= 13 - 0.75(12) + 8(1/2)

= 13 - 9 + 8/2

= 13 - 9 + 4

= 8

Therefore,

13 - 0.75w + 8x = 8

A local am radio station broadcasts at a frequency of 764 khz. calculate the energy of the frequency at which it is broadcasting

pentagon [3]

The frequency of the emitted radio waves is:
$f=764 kHz = 7.64 \cdot 10^5 Hz$

The energy of a photon is given by:
$E=hf$
where h is the Planck constant and f is the photon frequency. Using the frequency given by the problem, we can find the energy of each photon of this radiation:
$E=hf=(6.6 \cdot 10^{-34} Js)(7.64 \cdot 10^5 Hz)=5.04 \cdot 10^{-28} J=5.04 \cdot 10^{-31} kJ$

Adia plans to wallpaper her bedroom. The measurements are 10’ by 12’ with 8’ ceilings. Part 1: What is the total area of the wal

Leokris [45]

10' x 12' are the dimensions for the floor and roof, both of which will not be covered with wallpaper.

The room will have two identical walls with the following dimensions:
10 x 8
12 x 8

The total area to be covered is:
2 x 10 x 8 + 2 x 12 x 8

Total area = 352 square feet
