Answer:

-7

Step-by-step explanation:

The arithmetic mean of the numbers - 16, - 9 and 4 is,

⇒ - 7

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

Given that;

Numbers are,

⇒ - 16, - 9 and 4

Now, We can formulate;

The arithmetic mean of the numbers - 16, - 9 and 4 is,

⇒ (- 16 + (- 9) + 4 ) / 3

⇒ (- 16 - 9 + 4) / 3

⇒ - 21 / 3

⇒ - 7

Thus, The arithmetic mean of the numbers - 16, - 9 and 4 is,

⇒ - 7

Answer:

45*x-10

Step-by-step explanation:

10 less than a number would give you

x - 10

and the product of a number means your multiplying and your multiplying 45 so you would get

45*x

add them together and you get

45*x-10

Answer:

Step-by-step explanation:

From -3 to -7 the distance is 4 (-3--7=4). Midpoint means that point -3 bisects the segment into two equal parts. So, the other endpoint is 4 units away from -3. Since -3+4=1, 1 is answer.

Answer:

Yes it is an isosceles triangle

Step-by-step explanation:

We just need to see if the distance between two points is the same as the distance with two others

Distance between AB = (4 -(-1))² + (7 - 2)² = c²

                                        5² + 5² = c²

                                        25 + 25 = c²

                                        c = √50

Distance between AC = (11-(-1))² + (8 - 2)² = c²

                                        12² + 6² = c²

                                        144 + 36 = c²

                                        180 = c²

                                        c = √180

Distance between CB = (11-4)² + (8 - 7)² = c²

                                        7² + 1² = c²

                                        49 + 1 = c²

                                        50 = c²

                                        c = √50

Hence, this is an isosceles triangle because AB and CB are congruent in length.

Answer:

x - 2y = 0

Step-by-step explanation:

The two lines have the same slope because they are parallel, and their equations have the same form as x-2y+3=0​, with only the constant (3) being different.  Solving this equation for y to find the slope, we get:

x + 3 = 2y, or y = (1/2)x + 3/2.  The line passing through (0, 0) with the same slope must then be y = (1/2)x; this line represents a proportional relationship because y is a constant multiple of x with the constant of proportionality 1/2.  This result may be rewritten as 2y = x or x - 2y = 0.

Step-by-step explanation:

The solution is: the surface area of the cylinder is 301.44 km².

Here, we have,

from the given diagram, we get,

For surface area of a cylinder:

A = 2(π) × (radius) × (height) + 2(π)×(radius squared)

For the first half of that equation:

2(π) × (radius) × (height)

2 × (3.14) × (4) × (8)

= 200.96 km²

Now the second half of that equation, the area of the circle ends:

2(π)×(radius squared)

= 2 × (3.14) × (4) × (4)

= 100.48 km²

Add them up:

200.96 km² + 100.48 km² = 301.44 km²

Hence, The solution is: the surface area of the cylinder is 301.44 km².
