Answer:
3348 ft
Step-by-step explanation:
sin 21° = BC/AB = 1200/AB
AB = 1200 / sin 21° = 1200 / 0.358 = 3352 ≈ 3348

Answer:
B The length is 5 inches, the width is 2 inches, and the height is 14 inches.
Step-by-step explanation:
The equation that desribes the volume of a party-favor bag is
The solutions of theis equation can be found among divisors of -140. The divisors are:
Note that
so
is the solution of the equation.
Hence,
the length is 5 inches, the width is 5-3=2 inches and the height is 5+9=14 inches.
Factorising an equation is putting it into bracket form.
This has square numbers and so needs double brackets
(5x - y) (5x+y)
If you then check this by multiplying the brackets out again you will get:
5x^2 - 5xy + 5xy - y^2
The positive and negative 5xy's cancel each other out and you are left with its original form. Your answer is
(<span>5x - y) (5x+y)</span>
Answer:volume of regular pyramid = 3388 units³
Explanation:Volume of regular pyramid can be calculated using the following rule:
volume of regular pyramid =
* area of base * height
volume of regular pyramid =
* length * width * height
Based on the comment you added above, we have:
length = 11 units
width = 11 units
height = 84 units
Substitute with the givens in the above equation to get the volume as follows:
volume =
* 11 * 11 * 84
volume = 3388 units³
Hope this helps :)
