Answer:
see below
Step-by-step explanation:
1/12 - 5/6 = -9/12
We need to get a common denominator of 12
1/12 - 5/6*2/2 = -9 /12
1/12 - 10/12 = -9/12
Since the denominators are the same, we can subtract the numerators
1-10 = -9
-9/12 = - 9/12
We can simplify -9/12 by dividing the top and bottom by 3
-9/3 = -3
12 /3 = 4
-9/12 = -3/4
1.8 divided by 7.74 is 0.23 .
And 56.4 divided 4.7 is 12 .
Answer:
x = 55° (nearest degree)
Step-by-step explanation:
Trig ratios:
where 
is the angle, O is the side opposite the angle, A is the side adjacent to the angle, and H is the hypotenuse of a right triangle
Given:
- A = 3.3
- H = 5.7
⇒ x = 55° (nearest degree)
Answer:
-13
Step-by-step explanation:
Subsitude -2 to where x is and you get -1o then subtract by -3 and the total is -13
Answer:
8m
Step-by-step explanation:
Answer:
Step-by-step explanation:
Area of a triangle = 1/2 * b * h
Parameters from the question:
Area = 60 m^2
Base (b) = 15m
Height (h) =?
Let's invoke the formula and solve for "h"
Therefore:
Area = 0.5 * b * h
60 = 0.5 * 15* h
60 = 7.5 * h
Divide both sides by 7.5 to make h independent.
h = 60 / 7.5
h = 8m
