Answer:
5^2 < 2^5
Step-by-step explanation:
2^5 = 2x2x2x2x2 = 32
5^2 = 5x5 = 25,
since 25 is less than 32, the comparison 5^2 < 2^5 is correct, or 25 < 32
Answer: D = 300 km
Total distance travelled is 300 km
Step-by-step explanation:
Distance = speed × time
The total distance travelled is the sum of the two distance travelled during the phases of speed.
D = v1t1 + v2t2 .....1
Given ;
speed v1 = 60km/hr ; v2 = 120km/hr
Time taken t1 = 1 hr ; t2 = 2 hr
Substituting the given values into equation 1, we have;
D = 60×1 + 120×2 = 60 + 240
D = 300 km
Total distance travelled is 300 km

Answer:
78º
Step-by-step explanation:
<u>Note</u> : -
In mathematics, the reference angle is defined as the acute angle and it is measuring less than 90 degrees. It is always the smallest angle, and it makes the terminal side of an angle with the
x - axis.
<u>S</u><u>t</u><u>e</u><u>p</u><u> </u><u>1</u> : -
Find where 192º lies in which quadrant.
192º lies in 3rd quadrant ( between
180º and 270º )
<u>S</u><u>t</u><u>e</u><u>p</u><u> </u><u>2</u> : -
Subtract : 270 - 192
270 - 192 = 78º
( Since, 192º is greater than 180º, is subtracted from 270º )
<u>A</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u> : -
78º is the reference angle for 192º.
