Answer: 215.6 meters
Step-by-step explanation:
Formula of a polygon: A= 1/2ap
a = apothem
p = perimeter
Since the polygon has 7 sides, you need to multiply 7 by 7.7 (side length) to find the perimeter which would be 53.9
A= 1/2 x 8 x 53.9
A = 215.6 meters
<span>Consider the solid s described below. the base of s is the region enclosed by the parabola y = 5 - 5x2 and the x-axis. cross-sections perpendicular to the x-axis are isosceles triangles with height equal to the base. find the volume v of this solid.</span>
Answer:
2. A
3. C
4. B
Step-by-step explanation:
2. To answer # 2, just add all the sides together...
(5x-7) + (3x-4) + (2x-6)
= 10x - 17
3. To answer # 3, divide/mulitply both the numerators and denominators by the same number and check to see if that answer matches the displayed answer...
a) 28 divided by 7 is 4, so divide the whole fraction by 7 to see if the fraction is proportional...
28/7 = 4
49/7 = 7
b) 4 goes into 16 4 times so multiply 
by 4...
4 x 4 = 16
7 x 4 = 28
=
c) 4 goes into 16 4 times so multiply the whole fraction by 4...
4 x 4 = 16
7 x 4 = 28
≠ 
d) 4 goes into 20 5 times to multiply the whole fraction by 5...
4 x 5 = 20
7 x 5 = 35
C is the answer because the fractions are not proportional.
4) 25% is a quarter of 100%. A third of 100% is 75%.
$120 - 0.25($120) = $90
Another expression for the for sale price is...
B) 0.75($120) = $90
First off, why is this in the mathematics section lol. Anyways, the essay looks good, but you can remove some unnecessary information. The reader doesn't need to know that the author is 14. Knowing the age of an author won't help support your argument.
Also, you say, "For example during the pandemic situation there were some quick changes to it like the vaccines being made...".
I would say instead, "During the pandemic, there were some rapid changes that took place to correct the pandemic like the vaccines being made...". Other than that, the essay looks good!
