Answer: 53.659 seconds
Step-by-step explanation:
Given: Vega swam her leg of the race in 27.98 seconds.
Janice swam her leg of the relay race in 25.679 seconds.
Then , their combined time for their part of the relay = (Time taken by Vega) + (Time taken by Janice)
= 27.98 seconds +25.679 seconds
= (27.98+25.679) seconds
= 53.659 seconds
Hence, their combined time for their part of the relay = 53.659 seconds
Answer:
B. 40 degrees and 140 degrees.
Step-by-step explanation:
please tell me if this is wrong
X=22. The supplementary angle is 90°, so the 66° angle, plus (x+2) has to add up to 90° too.
2 goes into both numbers, so divide both by 2;
10 ÷ 2 = 5
42 ÷ 2 = 21
so 10/42 in simplest form is: 5/21
Answer:
3 : 5, 4: 5
Step-by-step explanation:
Let the common multiplier of the given ratios be x.
Therefore, lengths of the legs of right triangle would be 3x and 4x
By Pythagoras Theorem:
