Answer:

b. $10

Step-by-step explanation:

to find the median of a set of numbers you put them in order from least to greatest and the median is the middle number if there is an even amount of numbers you would add up the two middle numbers and then divide them by two. And if you have the median and are missing one of the two numbers you would multiply the median by two and subtract the number you know.

Answer:

Hello first one is 4.

Second one is 8

Step-by-step explanation:

First one is f(0). It means you should put zero in the place of x

0 is less than 5 so you should put zero in x+4=f(x)

For the second one do like the first one.

I hope you understand

If < A and < B form a linear pair, and < A = x - 13 degrees, and < B = x + 7 degrees, then find x. Select one: a. 12

Andreas93 [3]

The correct value of "x" will be "93".

According to the question,

A linear pair of sum to 180°,

then

→ $x-13+x+7=180$

→ $2x -6=180$

By adding "6" both sides of the equation, we get

→ $2x-6+6=180-6$

→ $2x=186$

→ $x = \frac{186}{2}$

→ $x = 93$

Thus "option d" is the right answer.

A cylinder has a height of 18 millimeters and a radius of 18 millimeters. What is its volume? Use ≈ 3.14 and round your answer

solong [7]

Answer:

$Volume = 18312.48$

Step-by-step explanation:

Given

$Height (h) = 18mm$

$Radius (r) = 18mm$

Required

Determine the volume

The volume of a cylinder is calculated as thus:

$Volume = \pi r^2h$

Substitute values for r and h

$Volume = 3.14 * 18^2 * 18$

$Volume = 18312.48$

<em>Hence, the volume of the cylinder is 18312.48mm³</em>
