Why is the sky orange and red at sunrise and sunset?
Gases absorb orange and red light.
Blue wavelengths are absorbed by the atmosphere.
The thick atmosphere scatters all but longer wavelengths.
Only short wavelengths are radiated from the Sun in the morning and evening.
Answer:
1. y= -1/4
Step-by-step explanation:
y/5 + 3/10 = (y+2)/7
Get a common denominator for the left hand side
2y/10 + 3/10 = (y+2)/7
(2y+3)/10 = (y+2)/7
Using cross products
(2y+3) *7 = 10*(y+2)
Distribute
14y+21 = 10y+20
Subtract 10y from each side
14y-10y +21 = 10y-10y+20
4y+21 =20
Subtract 21 from each side
4y+21-21 = 20-21
4y = -1
Divide by 4
4y/4 = -1/4
y = -1/4
Answer:
Product before increasing: 4200
x after increase: 60 * 105% = 63
y after increase: 70 * 110% = 77
Product after increasing: 4851
Percentage increase in the product: 4851 / 4200 * 100 = 115.5%
Answer:
If you plug in 0 for the x value, you get y=−11.
