Answer:
44 in²
Step-by-step explanation:
The figure is composed of a triangle, a rectangle and a trapezium.
Area of the triangle = bh =
× 3 × 4 = 6 in²
Area of the rectangle = lb = 10 × 3 = 30 in²
Area of trapezium = h (a + b)
where h is the height and a, b the parallel bases, thus
area of trapezium = × 2 × (5 + 3) = 1 × 8 = 8 in²
Total area = 6 in² + 30 in² + 8 in² = 44 in²
Answer:
C.
Step-by-step explanation:
We use the Quadractic Formula:
*Excuse the bad ± (plus or minus) sign. It wouldn't let me put it in the equation maker
<em>a</em> = 1
<em>b</em> = -5
<em>c</em> = 7
Step 1: Plug in our variables
Step 2: Solve
√-3 is equal to √-1 times √3, and √-1 is equal to imaginary i
Thus, we have:
(5 ± i√3)/2 or (5 + i√3)/2 and (5 - i√3)/2
Answer:
36
Step-by-step explanation:
Let the number of girls in club be
Number of boys = 30
Number of boys is 10 times half the number of girls
i.e.
Total number of boys and girls in club = 30 + 6 = 36
