Answer:
The total amount of water needed is 540 cubic inches.
Step-by-step explanation:
A cubic prism has three dimension. Lenght l, width w and height h.
It's volume is:
In this question:
Dimensions in inches, so the volume will be in cubic inches.
The volume is 600 cubic inches.
What is the total amount of water needed, to the nearest cubic inch, to fill 90% of the aquarium with water?
This is 90% of 600. So
0.9*600 = 540
The total amount of water needed is 540 cubic inches.
We have been given an image of a circle. We are asked to find the value of each variable.
We can see that angle b corresponds to diameter of circle. We know that the measure of an angle that is inscribed to the diameter of a circle is 90 degrees . Therefore, the value of b will be 90.
we can see that angle is an inscribed angle of arc 99 degrees. We know that measure of an inscribed angle is half the measure of inscribed arc.
Therefore, the value of a is 49.5 units.
We know that measure of all angles of a triangle is 180 degrees. The measure of 3rd angle will be half the measure of c, so we can set an equation as:
Therefore, the value of c is 81.
