X=6 because 2*6=12 and 12+4=16
Answer:
It’s 850
Step-by-step explanation:
Divide the figure into 3 shapes, first one being 10ft times 5ft times 5, followed by 20 times 5 times 5 the another with 10 times 5 times 5. I got 850
The volume of the shaded region is 1650 cubic feet.
Answer:
8 seconds.
Step-by-step explanation:
To solve this question, we need to find the time,
, when
, that is, when the height of the object above the ground is 0 feet.
Substituting
feet per second and
gives the quadratic:

Since 128 is divisible by 16, it can be reduced to
.
We must now solve for
.
We can easily see that one answer to the equation is 0,
(we need not concern ourselves with the 16 outside of the parenthesis as in the equation above, since 16 multiplied by 0 is 0). However this is the time the object is released into the air.
The second answer,
is also easy to see by inspection:
.
Therefore the object lands 8 seconds after it is thrown.
<h3><u>
Answer:</u></h3>
The simple interest is $3352.
<h3><u>
Step-by-step explanation:</u></h3>
Using PRT/100, we can find the interest.
- => 41,900 x 4 x 2/100
- => 419 x 4 x 2
- => $3352
<h3><u>Conclusion:</u></h3>
Therefore, the simple interest is $3352.
