To find the area of this figure, there is two choices
1. cut it into 3 rectangles.
2.find the missing rectangle in the middle......
I likes 2 better $_$ :}
find the missing area in the middle, 12* 23 = 276
the area of the whole figure 31*69-276=1863m²
I believe it's 12 because 5*16=80. So, then you would subtract 4 from 16 and gat 12.
Answer:
The answer is pie
Step-by-step explanation:
I know best
Each petal of the region
is the intersection of two circles, both of diameter 10. Each petal in turn is twice the area of a circular segment bounded by a chord of length
, which implies the segment is subtended by an angle of
. This means the area of the segment is
This means the area of one petal is
, and the area of
is four times this, or
.
Meanwhile, the area of
is simply the area of the square minus the area of
, or
.
So
(provided these regions are indeed disjoint; it's hard to tell from the picture)
Answer:
50 total penguins
Step-by-step explanation:
In the following example x = the total number of penguins.
Set it up as follows.
15 over x = 30 over 100
Cross multiply the numbers. (30 times x) and (15 times 100)
This results in 30x = 1500.
Divide both sides by 30 which results in x = 50.
This means that there is a total of 50 penguins.
In the following example x = the number of Emperor penguins.
If you would like to double check this, set up as follows.
x over 50 = 30 over 100
Cross multiply the numbers. (30 times 50) (100 times x)
This results in 100x = 1500.
Divide both sides by 100 which results in x =1 5.
This means that there are 15 Emperor penguins.
