Answer:
400 meters
Step-by-step explanation:
So it goes 20 meters every second. So you would multiply that by 20 seconds to get 400 meters.
first one: 9 x 10^8th i thinkor just 90 million
second one: 7 billion. 7 x 10^9
Multiply the decimal version of the percent by the total number of hours in a day (24). For example, 26% of the day is 0.26 * 24 = 6.24 hours.
Answer:
D, E
Step-by-step explanation:
(4x - 1) ^2 = 11 => (take square roots of both sides)
4x - 1 = +\- sqrt(11) => (Add 1 to both sides)
4x - 1 + 1 = 1 +\-sqrt(11) =>
4x + 0 = 1 +\- sqrt(11) => (Divide both sides by 4)
x = ( 1 +\- sqrt(11) ) /4
Which are choices D and E
Answer:
x = 40
Step-by-step explanation:
x + 100 + x = 180 {Straight line angles}
2x + 100 = 180 {subtract 100 from both sides}
2x = 180 - 100
2x = 80 {Divide both sides by 2)
x = 80/2
x = 40
