Which table shows a no change linear relationship?
Phantasy [73]

Answer:

C

Step-by-step explanation:

Each of the tables is a linear relationship. Linear relationships increase or decrease steadily by adding or subtracting a constant. Table A increases by 5. Table B decreases by 2. Table C doesn't change. Table D increase by 4.

A "no change" means the y values never change. The constant is 0 and is a horizontal line. Table C is the solution.

How many times smaller is the surface area of a cube if the side length is multiplied 1/2<br>​
Tju [1.3M]

Answer:

1/4, or 4 times smaller

Step-by-step explanation:

Since the surface area of a cube is just the combination of the area of all of the square sides, and the formula for those is s^2, if the side length was decreased by 1/2 then the surface area would decrease by (1/2)^2=1/4. Hope this helps!

Name an example of an acute angle, right angle, and straight angle according to their angle measures
oksian1 [2.3K]

Acute: anything less than 90 but greater than 0

so, m<CAD


right: angles at exactly 90 degrees, so m<AEC,

and obtuse angles are anything greater than 90 but less than 180 degrees,

so CDA (you can tell by the picture that it is bigger than 90- 90 degrees is exactly perpendicular)
