Answer:
-17
Step-by-step explanation:
x - (-z)
Subtracting a negative is like adding
x+z
x = -4 and z = -13
-4 + -13
-17
Assuming your looking for volume.
The following formula is used for calculating the volume (V) of a cone.
- where r is the radius and h, the height.
- Substitute r = 3 and h = 5 into the formula.
⇒ 
≈ 
Answer: Scalene triangle
Step-by-step explanation:
A Scalene triangle has all of its three lengths to be different. The traingle above can not be an equilateral triangle too because all the sides aren't equal.
Also, it's not an isosceles triangle since two of its sides are not thesame. It's not a right angle triangle as the square of the hypothenuse isn't equal to the addition of the square of the other two sides.
Answer:
8 5/12 > 8 3/8
Step-by-step explanation:
The integer parts of the numbers are the same, so we can find the desired result by comparing the fractions. To do that, we can subtract one from the other, or we can simply write them both with a common denominator.
<u>Subtracting</u>:
5/12 -3/8 = (5·8 -12·3)/(12·8) = 4/(12·8) = 1/24 > 0
so we have ...
5/12 > 3/8
8 5/12 > 8 3/8
__
<u>Common Denominator</u>:
The denominators of the fractions are 12 and 8. The least common multiple of these numbers is 12·2 = 8·3 = 24. Then the numbers can be written as ...
8 5/12 = 8 10/24
8 3/8 = 8 9/24 . . . . . . this is less than 8 10/24
Then the appropriate relation between the numbers is ...
8 5/12 > 8 3/8
Answer:
an area
Step-by-step explanation:
A two-dimensional (2D) figure is like drawing on a sheet of paper. It has some width and some length, but no height.
So, you cannot calculate its volume, since it has only 2 dimensions, a volume requires 3 dimensions.
The only spacial measure you can do on a two-dimensional figure is its area (basically length * width, if we talk about a rectangle, other forms have different calculation methods).
