<h3>Given</h3>
1) Trapezoid BEAR with bases 11.5 and 6.5 and height 8.5, all in cm.
2) Regular pentagon PENTA with side lengths 9 m
<h3>Find</h3>
The area of each figure, rounded to the nearest integer
<h3>Solution</h3>
1) The area of a trapezoid is given by
... A = (1/2)(b1 +b2)h
... A = (1/2)(11.5 +6.5)·(8.5) = 76.5 ≈ 77
The area of BEAR is about 77 cm².
2) The conventional formula for the area of a regular polygon makes use of its perimeter and the length of the apothem. For an n-sided polygon with side length s, the perimeter is p = n·s. The length of the apothem is found using trigonometry to be a = (s/2)/tan(180°/n). Then the area is ...
... A = (1/2)ap
... A = (1/2)(s/(2tan(180°/n)))(ns)
... A = (n/4)s²/tan(180°/n)
We have a polygon with s=9 and n=5, so its area is
... A = (5/4)·9²/tan(36°) ≈ 139.36
The area of PENTA is about 139 m².
Answer:
5.40 dollars
Step-by-step explanation:
3 3/4 lb= $20.25
1lb=?
Cross multiply
20.25* 1/ 3 3/4
Which is 5.4
The answer is 5.40 dollars
The answer is A !! Did it step by step , don’t forget to put a brainliest if you can ;)
<span>Given
situation : 2 improper fraction is multiplied. Now is the product always more
than than 1?
Yes, the product is always more than 1. Because take note that in improper
fraction, the numerator is always higher compare to the denominator of the
given fraction. That means when you divide the numerator from the denominator,
the answer would always be more than 1.
Example:
=> 5 / 4 x 4 / 2
=> 20 / 8 or equals to 5/2
now divide
=> 5 / 2
=> 2 1/2
