Answer:
1) 36 square units.
2) 190 square units.
Step-by-step explanation:
As you can see, the figures are trapezoids, therefore, you can calculate the area of each one of them with the following formula:

Where:
<em>B</em> is the longer base,<em> b</em> is the shorter base and <em>h</em> is the height.
Then:
1) 

2) 

Answer:
1760 Hz
Explanation:
The equation for the displacement has the following general formula:
d = A sin(wt)
where:
A is the amplitude
w is the angular frequency
the given equation is:
d = 0.6 sin(3520πt)
We can note that:
w = 3520 π rad/sec
Now,
w = 2πf where f is the frequency
Therefore:
3520π = 2π*frequency
This means that:
frequency = 1760 Hz
Hope this helps :)
Answer:
Step-by-step explanation:
<u>Original price </u>
<u>Sale price</u>
- $24.98*1.5 = $37.47 for two hats
<u>Total cost </u>
<u>Hats sold:</u>
- 187.35/37.47 *2 = 10 hats
Answer:
V = a³/8
Step-by-step explanation:
The volume of the original cube is the cube of the side length:
V = a³
When the side length is reduced to half its former value, the new volume is ...
V = (a/2)³ = a³/2³
V = a³/8 . . . . volume of the new cube
