Answer:
The length of the case is 17 inches.
Step-by-step explanation:
A flute case is shaped like a rectangular prism with dimensions:
- height = 5 inches;
- width = 3 inches;
- length = x inches.
The volume of the case is 255 cubic inches.
Use formula for the volume of the rectangular prism:
Thus,
The length of the case is 17 inches.
Answer:
A. 25/60 = x/100
This was correct on Edge btw :)
Answer:
1\4
Step-by-step explanation:
So you know that the sum of angles in a triangle is 180°.
You know two of the angles in triangle WXZ. The two angles are angle WXZ, which is 50° and angle XWZ, which is 90°.
Now you can calculate angle WZX, by:
180-50-90=40°.
Answer:
- <u><em>Sometimes.</em></u>
Explanation:
The statement is <em>P forward Q is true and q is true, then p is true sometimes always or never.</em>
<em />
That, written using logical symbology, is:
- p → q,
- q is true
- then p is ?
p → q is known as a conditional statement.
When the conditional p → q is true and p is also verified to be true, you must conclude that q is (necessarily) true (else the conditional would be false).
That also means that if q is verified to be false (not true), p must necessarily be false (else the conditional would be false).
Nevertheless, the fact that q is true, does not permit to conclude whether p is true or false: p can be either true or false when you only know that q is true.
Then, you cannot tell that p is true always or never; some times it could be true and others false.
