Answer:
x=2
Step-by-step explanation:
divide -5 to both sides to isolate the x. two negatives make a positive therefore x=2.
i hope this helps :)
The parallel cross-sections of a cylinder, cone, sphere, and pyramid are a circle, a circle, a circle, and a square.
We are given some solids. Solid geometry, or stereometry, is the traditional name for the geometry of three-dimensional Euclidean spaces in mathematics. Stereometry is concerned with measuring the volumes of various solid figures. The given solids are a cylinder, cone, sphere, and pyramid. We need to find the parallel cross-sections of the given solids. Parallel cross sections are cross sections of a solid that are parallel to each other. A cross section is a straight slice of an object. The parallel cross-sections of a cylinder, cone, sphere, and pyramid are a circle, a circle, a circle, and a square.

Answer:
13:6 ; 9:4 ; 5:2 ; 20:7 ; 10:3
Step-by-step explanation:
The unit measurement of the a volume in mm is mm³(millimetres cube.)
<h3>How to find volume ?</h3>
Volume is is defined as the space occupied within the boundaries. The objects are usually solid objects.
The volume of a 3 dimensional figure is the product of the base area and the height.
Therefore, the units of volume is measured in cubic units.
The volume of a prism with side lengths measured in millimetres is 20.
Therefore, the measurement can be represented as follows:
20 mm³

Answer:
There will be 22.5 grams left after 32 hours.
Step-by-step explanation:
A half-life is how long it takes for half of the amount to go away. In this case, we see that we have two half-life periods worth, which you can determine by dividing the total time by the half-life time.
32hrs/8hrs = 4 half lives.
Now we can raise 1/2 to the power of how many half lives we have (2). Then we multiply that by the amount in the sample.
(1/2)^4 * 360
1/16 * 360
22.5 grams
And this is an exponential function.
