if those r coordinates you can use the Pythagorean the to find the distance
plot the point and create a right triangle with the origin
could up the spaces and depending on the number, subtract the side from the hypotenuse or add the sides to find the hypotenuse
then square root both sides
Answer:
The answer would be -a
Step-by-step explanation:
In the examples,
5 + (-5) = 0
-1.33 + 1.33 = 0
THat means there will be a negative then a positive, or a positive then a negative.
INVERSE is the key word in this problem.
50 pieces because when you do 25 times two fits you 50 fits witch can be reduced to 10
Answer:
B. 264
Step-by-step explanation:
Although the figure may look odd, This is just a square pyramid on it's side.
So, to find the surface area, we need to find the area of the base and the area of the faces and add them together.
To find the area of the base:
Since the base is a square, all we have to do is multiply 8 by itself.
8 * 8 = 64
The area of the base is 12.5 in^2
To find the area of the faces:
Since the faces are triangles, we have to multiply the length by the height and divide by 2.
8 * 12.5 = 100
100/2 = 50
The area of one face is 50 in^2
To find the surface area:
Add the area of the base to the area of all 4 sides.
64 + 4(50)
64 + 200 = 264
The surface area of the pyramid is B. 264 in.^2
<h3>Answer :</h3>
There are two statements here, showing quantities in real world which are additive inverse of each other :
2. Noa hiked 2 mi up a mountain trail and then hiked 2 mi down the trail.
here, we can depict going up as +2 miles and going down the trail as -2
4. A hot-air balloon ascends 2000 ft from the ground and then descends 2000 ft.
And here we can assume going up the ground aa + 2000 ft and going down aa - 2000 ft .
