There are 10 minutes in 600 seconds
1 minute is 60 seconds
Triangle XWV is an equilateral triangle(every angle is 60). So both angle V's are vertical angles, which means the are the same(60). Y is 90. So once you have 60 and 90 in triangle YZV, you know the last angle(Z) is 30. But since angle Z is 30 and angle X is 60, they are complementary and not supplementary(which adds up to 180)
Answer:
(40 + 2x)feet
Step-by-step explanation:
see attachment for the figure.
Let 'L' represents the length of the rectangular swimming pool i.e 40ft wide.
and pool is bordered by square tiles that are x feet in length surrounding the pool
therefore,
In order to find the longest side of the pool and the tile border, take the sum of length of the swimming pool i.e 40 adding two times the wide of the square tiles
(40+2x)feet.

Answer:
D
Step-by-step explanation:
4.2 precent of 5000 is 210. You multiply that by the year (4) because he paid 4.2 of 5000 anually. If you multiply that the answer should be 840.
3.9 precent of 5000 is 195. If you multiply that again by 6 (the year) because he paid 3.9 of 5000 anually. If you multiply that your answer should be 1170.
Now after all that subtract. 1170-840= 330
