The diagram shows two objects made of the same kind of glass. At left, a 3 dimensional figure labeled X with 2 triangular sides
opposite 1 another and 3 rectangular sides. At right, a cube labeled Y. Which statement best compares light passing through the two blocks? Light is not separated by wavelength as it exits Object X. Light moves faster as it moves within Object X. Light is only refracted once as it passes in and out of Object Y. Light is refracted less when it passes through Object Y.

Answer:
- $500
Step-by-step explanation:
<h3>Given</h3>- Sofa = s
- Love seat = l
- Chair = c
- Sofa and love seat cost = $1300
- Sofa and 2 chairs cost = $1400
- Sofa, love seat and one chair cost = $1600
- Love seat = ?
<u>Equations as per given are:</u>
- s + l = 1300
- s + 2c = 1400
- s + l + c = 1600
<u>Subtract equation 1 from equation 3:</u>
- s + l + c - s - l = 1600 - 1300
- c = 300
<u>Considering this in the equation 2:</u>
- s + 2*300 = 1400
- s = 1400 - 600
- s = 800
<u>Substituting s in the equation 1:</u>
- 800 + l = 1300
- l = 1300 - 800
- l = 500
<u>Answer:</u> Love seat costs $500
Hello!
To find how much money total will be in the account after four years, you need to use the function, , as seen above. In this function, a is the starting value, r is the interest rate, and t is the amount of time (in years).
Before substituting values into the function, we need to convert 3% into a decimal. Remember that all percentages are out of 100, so we divide 3 by 100 and remove the percentage sign, or move the decimal two places to the left.
3/100 = 0.03 | 0.03 is the interest rate.
With all the necessary values, we can find the total amount in the account. In this case, a = 1200, r = 0.03, and t = 4.
y = 1350.610572, which can be rounded to 1350.61 dollars.
Therefore, after 4 years, the total amount in the account will be about 1350.61 dollars.
