Answer:
B
Step-by-step explanation:
-(-a)/b = a/b
Option A is not equal to a/b
But Option B is, after cancelling out the negative sign
1 mile is 5,280 feet, so 12,000 feet would be 2.27 miles.
Answer:
x = 4
Step-by-step explanation:
To begin, first find Angle SUT.
Knowing that SUH is a straight line, Angle SUT plus 100 degrees should equal 180 degrees. Angle SUT is 80 degrees.
The sum of all the degrees in a triangle is also 180 degrees.
SO
(4x + 4) + (21x - 4) + 80 = 180
25x + 80 = 180
25x = 100
x = 4
Answer:
A
Step-by-step explanation:
The sequence of positive odd numbers is
1, 3, 5, 7, ......
This is an arithmetic sequence with common difference d
d = 3 - 1 = 5 - 3 = 7 - 5 = 2
The sum to n terms of an arithmetic sequence is
= 
[2a + (n - 1)d ]
where a is the first term
here a = 1, d = 2, n = 12, hence
= 
[1 + (11 × 2) ]
= 6 [ 2 + (11 × 2) ]
= 6 × 24 = 144 → A
