Answer:
speed of light = 3 x 10^8 meters / second There are 3,600 seconnds per hour so,
speed of light = 3 x 10^8 meters / second * 3,600 = 1.08 x 10^12 meters / hour
1.496 x 10^11 meters ÷ 1.08 x 10^12 meters/hour = .1385 hours which rounds to
.139 hours
Step-by-step explanation:
Answer: $553.20
Step by step explanation: Since they took the price down 29% multiply the price by 1.29 to add the 29 percent back to the total amount. 428.84 * 1.29 = 553.20
Answer:
RS=19
Step-by-step explanation:
Simplify both sides of the equation.
Answer:
972
Step-by-step explanation:
The first term is (9x)^3, so the coefficient of x is 9. Since the degree is 3, the second term must have a multiplier of (3 choose 1). 1458 / (3 choose 1) = 486.
486 / (9^2) = 6. Therefore, the coefficient of y must be 6. Since the second term is negative, the coefficient of y is also negative. Thus, this can be written as (9x-6y)^3. Solving for the xy^2 term gives us (3 choose 2) * 9 * 6^2 = or the third option.
