Answer:
27,000
Step-by-step explanation:
round up for 5+ round up
if its 4 or below you round down, lets look in the tens place and we see a 1 so we round down and the 1 and the rest of the numbers behind it will become 0's so the answer is 27,000
note: I added a chart for you to help you know where to put your items, even for decimals
and i have attached a blank chart just in case
Answer:
160%
Step-by-step explanation:
138-100%
355-x%
355*100/138=257.2%~260%
260%-100%=160%
Answer:
The ladder will go approximately 35.71 ft up the building.
Step-by-step explanation:
The 50 ft ladder is leaning against a building and the base of the ladder is 35 feet from the base of the building.
It means the ladder will form a right triangle with the building with the following dimensions:
Using the Pythagorean Theorem to determine the height,
Here,
Substitute the given values into the equation to determine the height:
We know that height can not be negative. Thus,
ft
Therefore, the ladder will go approximately 35.71 ft up the building.
It is in form (x,y) (ususally)
7.5 and 12
there is something called a coordinate system where a line called the y axis runs vertically for infinity and a line perpendicular to it, crosses it. the other line is called the x axis which also extends for infinity
the point where they cross is point (0,0) or the origin
basically the numbers tell you how far you are from the axises
on the y axis, + numbers are up and - numbers are down
on the x axis, + numbers are to the right and - numbers are to the left
7.5=x and 12=y
+7.5 is positive
7.5 means that the point is 7.5 units to the right of the origin in relation to the x axis
12 is positive
12 means that the point is 12 units up from the origin in relation to the y axis
