Answer:
38 in²
Step-by-step explanation:
The area (A) of a trapezium is calculated using the formula
A =
h (a + b)
where a, b are the parallel bases and h the perpendicular height
here a = 12, b = 7 and h = 4, hence
A = 0.5 × 4 × (12 + 7) = 2 × 19 = 38 in²
Substitute the given number into the equation
Sum = 180(15-2)
Solve brackets
180(13)
Which is equal to 2340
So, the sum of interior angles is 2340 degrees
Answer:
<h2><u><em>
no</em></u></h2>
Step-by-step explanation:
Can 10 people be divided into two groups with a ratio of 1 : 2?
Explain.
10 : 3 = 3.33
or 10 : 3 = 9 remaining 1
since it is not possible to divide a person into three parts, your answer is no
m = ![\frac{29}{18}](https://tex.z-dn.net/?f=%5Cfrac%7B29%7D%7B18%7D)
add
to both sides
m = -
+ ![\frac{11}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B11%7D%7B6%7D)
we require a common denominator for both fractions before adding
multiply numerator/denominator of -
by 2
multiply the numerator/denominator of
by 3
= -
+
= ![\frac{29}{18}](https://tex.z-dn.net/?f=%5Cfrac%7B29%7D%7B18%7D)
Circumference = 2 x pi x r
Circumference = 2 x 3.14 x 3.5m
Circumference = 21.98
Round to 22m
The answer is c. 22m
