What is the height of a trapazoid with an area of 9m squared and bases that measure 2.4 m and 3.6 m
kifflom [539]
The formula of the area of a trapezoid is equal to:
Area = (a+b) / 2 * h

Substituting the values.
9 = (2.4 + 3.6) / 2 * h
9 = 6 / 2  h
9 = 3h
h = 3

So the height of the trapezoid is equal to 3m.

atroni [7]
\bf \cfrac{model}{actual}\qquad 1:300\qquad \cfrac{1}{300}\qquad \qquad \cfrac{3\frac{1}{2}}{a}=\cfrac{1}{300}\implies \cfrac{\frac{3\cdot 2+1}{2}}{a}=\cfrac{1}{300}
\\\\\\
\cfrac{\quad \frac{7}{2}\quad }{a}=\cfrac{1}{300}\implies \cfrac{\quad \frac{7}{2}\cdot 300\quad }{1}=a\implies 1050=a

What is 3.5% as a fraction and decimal.
Stels [109]

Answer:

1. 3.5% is 35/1000 as a fraction and 0.035 as a decimal.

2. 2.31 is 231% and 231/100

3. 23/25 is 92% and 0.92

4. 33% is 33/100 and 0.33

Step-by-step explanation:

For converting from fraction to decimal, simply divide the top by the bottom.

For converting from decimal to fraction, depending on how many places there are, you choose what to divide by.  Ex: .002 (there are 3 places, it is divided by 1,000)

For fraction to percent, you divide the top by the bottom, make it a decimal, and move the decimal over two places to the right.
