Answer:
10.2 feet.
Step-by-step explanation:
We have been given that Derek places a standard 12-inch ruler next to the goal post and measures the shadow of the ruler and the backboard. If the ruler has a shadow of 10 inches. We are asked t find the height of the backboard, if the backboard has a shadow of 8.5 feet.
We will use proportions to solve our given problem as ratio between sides ruler will be equal to ratio of sides of background.
Therefore, the actual height of the back-board is 10.2 feet.
Answer: it can have at most one right angle but at most, 2 acute angles
Step-by-step explanation:
A triangle is a shape bounded by 3 sides and it has three angles.
The sum of the angles is 180 degrees
A right angle is 90 degrees. So a tight angled triangle has one of the angles equal to 90 degrees.
An acute angle is an angle lesser than 90 degrees.
An obtuse angle is an angle greater than 90 degrees but lesser than 180 degrees. Assuming we have a right angle triangle.
So a triangle can have at most one right angle while a triangle can have more than one acute angle. For example, a right angled triangle has two acute angles. So also, a triangle containing an obtuse angle has two acute angles
The number 100 represents <u>the number of trials</u> in the experiment.
49/100 represents the <u>experimental </u> of the coin landing heads up.
Answer:
± 13
Step-by-step explanation:
= ± 13, since
13 × 13 = 169 and - 13 × - 13 = 169
Answer:
It will take 7.5 or 7 and a half years for the population to reach 15,600!
Step-by-step explanation:
4% of 12000 is 480!
15600-12000 is 3,600!
3,600/480 is 7.5
