Answer:

35.75 meters squared

Step-by-step explanation:

The area of a trapezoid is denoted by: A=\frac{(b_1+b_2)*h}{2} , where b_1 and b_2 are the bases and h is the height.

Here, the two bases are 7 1/2 and 5.5 meters and the height is 5.5. So, just plug in the values:

A=\frac{(7\frac{1}{2}+5.5)*5.5 }{2}

7 1/2 is the same as 7.5: A=\frac{(7.5+5.5)*5.5 }{2}=\frac{(13)*5.5}{2} =35.75

Thus, the area is 35.75 meters squared.

Hope this helps!

9. If 15 men working 10 days earn $500. How much will 12 men earn working 14,
Leno4ka [110]

Answer:

Firstly need to understand the questions.

If 15 men working 10 days, They earn 500.

If 12 men working 14 days, how much they will earn?

Step-by-step explanation:

560

Solution:

15 men working for 10 days =500

1 man working for 1 day = 500/(10*15) =10/3

Now 12 men working for 14 days = 12*14*10/3 =560.

I am pretty sure that answer is right.

Thank you :)

Simplify the given expression below 4/3-2i
ANTONII [103]
So-called simplifying, really means, "rationalizing the denominator", which is another way of saying, "getting rid of that pesky radical in the bottom"


\bf \cfrac{4}{3-2i}\cdot \cfrac{3+2i}{3+2i}\impliedby \textit{multiplying by the conjugate of the bottom}
\\\\\\
\cfrac{4(3+2i)}{(3-2i)(3+2i)}\implies \cfrac{4(3+2i)}{3^2-(2i)^2}\implies \cfrac{4(3+2i)}{3^2-(4i^2)}\\\\
-------------------------------\\\\
recall\qquad i^2=-1\\\\
-------------------------------\\\\
\cfrac{4(3+2i)}{3^2-(4\cdot -1)}\implies \cfrac{4(3+2i)}{9+4}\implies \cfrac{12+8i}{13}\implies \cfrac{12}{13}+\cfrac{8}{13}i

2250 / 25000 = 0.09

then multiply by 100 to get the % = 9%
