Remark
Average Speed = Total distance divided by total time.
Total Time
2 hours + 3 hours = 5 hours. The total time is 5 hours.
Total Distance
d = rate * time
d1 = 40 km/hour * 2 hours = 80 km
d2 = 50 km/hour * 3 hours = 150 km
d = d1 + d2
d = 80 + 150 = 230 km
Average Speed
Av = Total distance / Total Time = 230 / 5 = 46 km/hr
Answer:
(of an algebraic expression) consisting of three terms.
Example:
3x2 − 3y2 + 2
Answer:
A number line with a point at 3 with a bold line pointing to the right stopping at the open circle at 5.
Step-by-step explanation:
Phyllis solved the compound inequality She began by first breaking the inequality into two separate inequalities and , then she correctly solved each for x:
1)
Rewrite this inequality:
Divide by 2:
Add 1:
Divide by 3:
2)
Divide by 2:
Add 1:
Divide by 3:
The solution to the compound inequality are all values of x which are greater than 3 or equal to 3 and less than 5. So, you have to plot point at 3, draw a bold line to 5 and plot open circle at 5. Hence, option
A number line with a point at 3 with a bold line pointing to the right stopping at the open circle at 5
is true.
The answer to your question would be A.
Hope you have a nice day!
1.997 x 10^2
8.9×10^-6.
5×10^-6
Answer:
1.997 x 10²
Step-by-step explanation:
The number with the highest exponent is the greatest value.
10² is bigger than 10⁻⁶ and 10⁻⁸, so 1.997 x 10² is your answer.
