Answer:

7(10− $2^{3}$ )+ $\frac{8}{2}$

=18

Step-by-step explanation:

7(10− $2^{3}$ )+ $\frac{8}{2}$

=7(10−8)+ $\frac{8}{2}$

=(7)(2)+ $\frac{8}{2}$

=14+ $\frac{8}{2}$

=14+4

=18

An FM radio station broadcasts at 84 megahertz (MHz). What is the energy of each photon in Joule? Use h = 6.6 * 10 ^ (- 34) * j

iragen [17]

Answer:

$E=5.544*10^{-26} J$

Step-by-step explanation:

The equation for photon energy is given by:

$E=hf$

Where:

$h=Planck\hspace{3}constant=6.6*10^{-34} \\f=Frequency\hspace{3}of\hspace{3}the\hspace{3}wave=84000000Hz$

This equation telling us that the higher the frequency of the photon, the greater its energy. And the longer the photon wavelength, the lower its energy.

So, replacing the data provided in the previous equation:

$E=(6.6*10^{-34} )*(84000000)=5.544*10^{-26} J$

Explain what happens when you round 4.999 to the nearest tenth

Reptile [31]

It would round to 5 because 4.999 is closer to 5 than a decimal (idk if that's 100%)

What is the answer to this equation “A = ?”<br><br> G(a + h) = M

sasho [114]

Answer:

a = M -Gh/G

Step-by-step explanation:

in order to make a the subject of fomular , you will open the bracket first and then combine the like terms.

G(a + h) = M

Ga + Gh = M

Ga = M - Gh

since G is disturbing a from standing alone, we divide both sides by G

Ga/G = M- Gh/ G

a = M -Gh/G

In a class of 29 students, 19 are female and 14 have an A in the class. There are 8students who are male and do not have an A in

masya89 [10]

SOLUTION

The total number of females =

$19$

if 14 have an A in the class, the number of students without A is:

$29-14=15$

8 male students do not have an A, therefore the number of female students without an A is:

$15-8=7$

The probability that a student does not have an A given that the student is female can be calculated thus:

$\frac{\text{Total number of female students without an A}}{Total\text{ number of female students in the class}}$ $\frac{7}{19}$

PLEASE HELP ME ANSWER QUESTION #1 and #2

BARSIC [14]

150 divided by 50 equals the amount of time it took her to drive there

3 hours

This is the answer because 150 divided by 5 equals 3 and more simply 50 + 50+ 50= 150
