The height of the ramp rise from the ground at its highest end to the nearest hundredth is 8.79 inches.
The situation forms a right angle triangle.
<h3>What is a right angle triangle?</h3>
A right angle triangle has one of its angles as 90 degrees. The sides can be found using trigonometric ratios.
Therefore, the hypotenuse of the right triangle formed is the length of the fiberboard.
The height of the ramp formed is the opposite side of the right triangle.
Hence,
sin 19° = opposite / hypotenuse
sin 19° = h / 27
cross multiply
h = 27 × sin 19°
h = 27 × 0.32556815445
h = 8.79034017034
h = 8.79 inches.
Therefore, the height of the ramp rise from the ground at its highest end to the nearest hundredth is 8.79 inches.

For the rectangle do 10x15 to get 150cm squared
14-10 is 4 so triangle height is 4
Width is 5 as given
4x5 is 20 divide by two as triangle so 10cm squared
150+10=160cm squared
Answer:
8/12 and higher. To ensure an accurate answer, are there other fractions to compare "7/12" to?
Step-by-step explanation:
Answer:
422.39 sq cm
Step-by-step explanation:
Find the area of the circle and subtract the area of the rectangle from it.
Circle area: pi*12^2, 144pi sq cm
REctangle area: 10*3=30sq cm
144pi-30≈422.39
This is like the equivalent to a jar with 4 green balls and 6 white balls, where you are picking 3. (The 4 green balls signify the friends from kindergarten.)
You want to solve the probability that the first two balls are green and the third is white.
First draw --> 4 green out of 10 balls --> 4/10 = 2/5
Second draw --> 3 green out of 9 balls --> 3/9 = 1/3
Third draw --> 6 white out of 8 balls --> 6/8 = 3/4
2/5 x 1/3 x 3/4
= 6/60
= 1/10
so the answer is 1/10 (or 10%)
