Answer:
155°
Step-by-step explanation:
The sum of the 4 interior angles of a quadrilateral = 360°
Subtract the sum of the 3 given angles from 360 for fourth angle
fourth angle = 360° - (60 + 45 + 100)° = 360° - 205° = 155°
500 yards = 1800 inches
7000 pounds = 3.5 tons
I hope this helped!
Sum = n/2[2a + (n - 1)d] where a = first term, n = number of terms and d = common difference
(a) 30/2(2 x 5 + (30 - 1) x d) = 1455
10 + 29d = 1455 / 15
29d = 97 - 10
d = 87 / 29 = 3
(b) 7/2(2 x 9 + (7 - 1)d) = 0
18 + 6d = 0
6d = -18
d = -3
Answer:
y^(-5/4)
Step-by-step explanation:
because
1/ (y^(5/4) = (1/y) ^(5/4) = y^(-5/4)
