Ok, so I'll make an example problem to show.
There's a forest in town and it's recorded that there are 5 bears and 100 squirrels in it.
First, you would make this a ratio so that would be 5:100. 5 being the bears and 100 being the squirrels.
To simplify it, just make it into a fraction. The first number, going from left to right, would be the numerator and 100 would be the denominator.
5
-----
100
To simplify, just divide by the greatest common factor which would be 5 in this case.
5 1
----- / 5 = ----
100 20
i don't think it exists anymore sorry
Answer:
B = 31.6
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan B = opp / adj
tan B = 28.2 / 45.8
taking the inverse tan of each side
tan ^ -1 ( tan B) = tan ^-1 (28.2/45.8)
B =31.62145
Rounding to the nearest tenth
B = 31.6
Answer:
(2, 1 )
Step-by-step explanation:
Assuming the centre of dilatation is the origin.
Then multiply each of the coordinates of B by 0.5 , that is
B(4, 2 ) → (4(0.5), 2(0.5)) → (2, 1 )
add 1 1/10 + 1 2/5
first get both fractions with the same bottom number: 2/5 = 4/10 ( multiply both numbers by 2)
so now you have 1 1/10 + 1 4/10 = 2 5/10
5/10 reduces to 1/2
so answer is 2 1/2 inches, and since the level is going down it would be negative 2 1/2 inches
