Answer:

Step-by-step explanation:

Square root can be written as a power.

Multiply the exponents.

The base area of this second rectangular prism is 51 cm²
The rectangular prism completely filled with sand has a base area of 85cm² and height of 15cm .
<h3>
</h3><h3>
volume of a rectangular prism</h3>
where
B = base area
h = height
Since the first rectangular prism was completely filled with sand and it completely filled the second rectangular prism, it means they both have the same volume.
Therefore,
volume of the first rectangular prism = volume of the second rectangular prism.
Therefore, the base area of the second rectangular prism can be calculated as follows:
volume = Bh
1275 = 25B
B = 1275 / 25
B = 51 cm²

9 + h = 55/5
9 + h = 11
11 - 9 = h
2 = h
The opposite of addition is subtraction, Subtract 9 from both sides, The opposite of multiplication is division, divide both sides by 5 is the first step, and final answer is h = 2.
Answer: First option.
Step-by-step explanation:
You can idenfity in the figure that
is formed by two secants that intersect outside of the given circle.
It is important to remember that, by definition:

Knowing this, you can set up the following equation:

Therefore, you must substitute values into the equation and then evaluate, in order to find the measure of the angle
.
