Answer:
57971014.49 Hz or 5.79 * 10^7 Hz
Step-by-step explanation:
Given that:
Speed of microwave (v) = 2,000,000 m/s
Wavelength, λ = 0.0345 m
Frequency :?
Using the relation :
v = fλ
f = v / λ
f = 2,000,000 / 0.0345
f = 57971014.49 Hz
Answer:
On Friday he did not make any bracelets He makes 8 more bracelets each day from Tuesday through Thursday
Step-by-step explanation:
He made 12 bracelets on Monday
For 3 days (from Tuesday to Thursday) he added 8 more each day)
8*3=24
24+12 = 36
M =12
T= 20 (12+8)
W=28(20+8)
Th=36(28+8)
F=36 (still has 36 because on Friday he did not make 8 more bracelets)
8*3=24
24+12 = 36
Answer:
x = 14
Step-by-step explanation:
x- 9 = 5
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. Add 9 to both sides of the equation:
x - 9 (+9) = 5 (+9)
x = 5 + 9
x = 14
x = 14 is your answer.

Answer: x=2
Step-by-step explanation:
Expand.
32−8x=7x+2
Add 8x to both sides.
32=7x+2+8x
Simplify 7x+2+8x7x+2+8x to 15x+215x+2.
32=15x+2
Subtract 22 from both sides.
32−2=15x
Simplify 32−2 to 30.
30=15x
Divide both sides by 15.
30/15=x
Simplify 30/15 to 2
2=x
Switch sides.
x=2
20,5,&7 are the coefficients
