Answer:
-3/5
Step-by-step explanation:
1 1/4 = 1 2/8
5/8 = 5/8
3/4 = 6/8
1/2 = 4/8
1 1/2 = 1 4/8
1 3/4 = 1 6/8
So, the biggest number (1 6/8) - the smallest number (4/8) = 10/8
But to subtract fractions, you must do a little rule
1x8=8+6=14/8 - 4/8 which is 10/8 or 1 1/4
The answer is C
Answer:
The sum of interior angles is found by using the following equation:
∑ of interior angles = (S - 2)180
S = sides.
Note that the sum is given to you, or 1620. Plug in 1620 for the sum:
1620 = (S - 2)180
Next, isolate the variable, s. Note the equal sign, what you do to one side, you do to the other. Divide 180 from both sides:
(1620)/180 = ((S - 2)180)/180
S - 2 = 1620/180
S - 2 = 9
Next, isolate the variable, s. Add 2 to both sides:
S - 2 (+2) = 9 (+2)
S = 9 + 2
S = 11

Answer:
75 meters.
Step-by-step explanation:
In this case, you are trying to find side length NO. In accordance to SOH CAH TOA, you can use a sine function to find the missing side length, since you are given the hypotenuse.
sin(49) = x / 100
x = sin(49) * 100
x = 0.7547095802 * 100
x = 75.47095802
So, the closest answer would be 75 meters.
Hope this helps!
