Answer:
1/4
Step-by-step explanation:
that is the answer
I found the constant which was -3
a = 1/4
b=-1
To find percentages, simply take the number that is not the "100%" number and divide it by the other number.
in this case,
52 / 130
complicated way of figuring it out if it makes more sense for you,
find how much is 1% of 130
130/100= 1.3
1% of 130 = 1.3
and then you just take 52 / 1.3

Answer:AB=15 ,angle A=53.1°,angle B=36.9°
Step-by-step explanation:
AB=√(12^2+9^2)
AB=√(12x12+9x9)
AB=√(144+81)
AB=√(225)
AB=15
TanA=12/9
TanA=4/3
A=Tan(inverse)(4/3)
A=53.1° angle A=53.1°
angle B=180-(90+53.1)
angle B=180-143.1
angle B=36.9°
Answer:
2
Step-by-step explanation:
(4 - 5) - (13 - 18 + 2)
According to PEMDAS, we should simplify the parentheses first.
= (-1) - (-3)
When you subtract a negative number, you are actually adding.
= -1 + 3
Now, add.
= 2
Hope this helps!
So to figure out 10% of this would be to remove the 0. that would be six. since 30÷10 is 3, we have to do 6×3. that would be 18, so 30% of 60 is 18
