Answer:
Step-by-step explanation:
A fraction is a quantity that is not a whole number. In maths, a fraction usually has a numerator and a denominator.
The numerator is the number above. While the denominator is the number below
an example of a fraction = 
4 is the numerator while 5 is the denominator
In this question, the numerator would be the number of times she walked to school in march(16). While the denominator would be the number of school days in March
the above fraction is not in its simplest form. To express in its simplest form, divide both numerator and the denominator by 8 . this gives
Answer:
I got 18 as my answer
Step-by-step explanation:
I made a triangle with the right side by dropping a vertical. Lets call the point straight down from C, E
Then I found the angle of D
sin θ = 5/13
θ = sin-¹(5/13)
θ≅22.619°
Then I found length of DE by
cosθ (remember we know what theta is) = X/13
12cosθ = X
X = 12
The length of DE is 12.
Since AD is 30, and the left side has two right angles we can do
AD - DE to find BC.
30-12 is 18
So since 4 was added to x then 2 subtracted from y, to reverse it
minus 4 from x and add 2 to y
(x,y)
(5,-3)
minus 4 and add 2
(1,-1) is the reverse translated
answer is last one
Just add 25 minutes. That's because they boarded at 3:55 and took 25 minutes to just go to the fair. So in 25 more minutes they got to the fair! so it would be 4:20 when they got to the fair.
For this case we must solve the following equation:
We remove the parentheses on the right side:
We add similar terms on the right side:
We subtract 
from both sides of the equation:
We add 9 to both sides of the equation:
We divide by 8 on both sides of the equation:
We apply square root to both sides of the equation:
We have two roots:
