Answer:
the bench costs $546
Step-by-step explanation:
subtract the cost of the table from the total
623 - 77 = 546
Answer:
<h2>70 > I+55</h2>
Step-by-step explanation:
The last inequality expresses better this situations.
Emma wants to beat her last record, which was 70 minutes. So, she needs to run in less than 70 minutes.
However, she already ran 55 minutes, the remaining time would be the variable I, so, the sum of them must be less than 70 minutes. So, there are two options to represent this:
I + 55 < 70 or 70 > I + 55.
Answer:
you are at a distance of 15.4 feet from the tree
Step-by-step explanation:
with the data they give us we can imagine a rectangular triangle, where the legs are the floor and the tree and the hypotenuse is the distance between the tip of the tree and the end of the shadow
we have to that the angle of elevation is 33 degrees
at the angle we will call it α
and the height of the tree we will call it opposite since it does not touch the angle
the distance we want to know we will call it adjacent
we see that it has (angle, adjacent, opposite)
well to start we have to know the relationship between angles, legas and the hypotenuse
a: adjacent
o: opposite
h: hypotenuse
sin α = o/h
cos α= a/h
tan α = o/a
it's the tangent
tan α = o/a
we replace the values and solve
tan α = o/a
tan 33 = 10/a
a = 10 / tan 33
a = 15.4
