Answer:

56 minutes

Step-by-step explanation:

14 people painting 14 walls is simply <em>double</em> (x2) 7 people painting seven walls.

We know this because 7 x 2 = 14

So, we will have to double the amount of time it takes them to paint.

28 x 2 = 56

It will take 56 minutes for 14 people to paint 7 walls!

Suggestion:

The width is the x value and the hight is the y value.

Plot the points on the graph as decimal if that helps.

The point at the bottom left is the origin (0,0)

I hope this helps.

1 cm = 2.5 ft
0.5 cm = 2.5 x 0.5 = 1.25 ft

Circumference = πD = π(1.25) = 3.93 ft

What conjecture can you make about the sum of the first 22 positive even numbers?
alekssr [168]

Answer:

A.) The sum of the product of the number of terms and the number of terms plus one.

Step-by-step explanation:

So, we have the sum of the first 22 positive even numbers:

S = 2 + 4+ 6 + ... + 44

We know the sum of such sequence is given by the (sum of the first number (2) and the last number (44)) multiplied by the number of terms (11).

S = (2 + 44) * 11 = 46 * 11 = 506

Answer A tells us it should be the sum of the number of terms (22) by the number of terms plus one (22 + 1 = 23).

S = 22 * 23 = 506

That's confirmed.

Answer B would give 22 * 21 = 462, so it's not right

Answer C would give 22 * 2 = 44, obviously not right

Answer D would give 22 * 22 = 484, close but not right.
