All of them
But if u had to pick one I would say addition or subtraction
Answer: 80%
80,000 = 100%
20,000 = 20%
100% - 20% = 80%
Always convert the main number into 100 and follow through with the other numbers
Answer:
67/500
Step-by-step explanation:
we have
The decimal number 0.134
Convert to a fraction number
Multiply by (1,000/1,000) the number
0.134*(1,000/1,000)=134/1,000
Simplify
Divide by 2 both numerator and denominator
67/500
I think the answer is -7/4.
Answer:
a.
and 41.6
b. 52.1
Step-by-step explanation:
a.
Considering the left side triangle the blue dotted side is the side "opposite" to the angle given and the side 24 is the side that is "adjacent" to the angle given. The trigonometric ratio tan relates opposite to adjacent. Also, let the blue dotted side be y.
<u>Note:</u> the exact value of tan 60 is 
Thus, we can write 
Approximate value (rounded to nearest tenth): 
b.
Considering the triangle to the right, the side "opposite" to the angle given (53 degrees) is 41.6 (just found in part (a)) and the side "hypotenuse" (side opposite to 90 degree angle) is x. The trigonometric ratio sine relates opposite and hypotenuse.
Thus we can write and solve:
