Answer:

Number of paints to buy, n = The total area of the walls, W / Area covered by a can of paint, p

Step-by-step explanation:

Let's

p = area covered by a can of paint

W = the total area of the walls

n = number of paint cans to buy

Number of paints to buy, n = The total area of the walls, W / Area covered by a can of paint, p

That is,

n = W / p

If the total area of the walls = 100 m²

A can of paint covers 5 m². Find the number of cans of paint needed?

Number of paints to buy, n = The total area of the walls, W / Area covered by a can of paint, p

n = W / p

= 100 m² / 5 m²

n = 20 cans of paint

Compute 1 + 2 + 3 +....+ 1,997 + 1,998 + 1,999
sp2606 [1]

Answer:

1 999 000

Step-by-step explanation:

Formula:

1+2+3+.\ .\ .+n=\frac{n\times \left( n+1\right)  }{2}

………………………………………

Then

1+2+3+....+1997+1998+1999=\frac{1999\times \left( 1999+1\right)  }{2}

1+2+3+....+1997+1998+1999=\frac{1999\times \left( 2000\right)  }{2}

1+2+3+....+1997+1998+1999=\frac{3998000  }{2}

1+2+3+....+1997+1998+1999=1999000

Andrea calls two truck rental companies to compare costs. Action trucks charges $80 for the day plus $0.22 per kilometer and tru
Amanda [17]

Answer:it will take 200 kilometers for the costs to be the same.

Step-by-step explanation:

Let x represent the number of kilometers that Andrea would have to drive for the total cost of renting from both companies to be the same.

Action trucks charges $80 for the day plus $0.22 per kilometer. It means that the total cost of x miles would be

80 + 0.22x - - - - - - - - - 1

Truck experts charges $100 for the day plus $0.12 per kilometer. It means that the total cost of x miles would be

100 + 0.12x - - - - - - - - - 2

Therefore, for the cost of renting from both companies to be the same,

80 + 0.22x = 100 + 0.12x

0.22x - 0.12x = 100 - 80

0.1x = 20

x = 20/0.1 = 200

Rashid [163]

Answer:

5 classes.

Step-by-step explanation:

You can use the 2^k rule to determine the number of classes for a frequency distribution.

The 2^k rule says that 2^k\geq n where

k is the number of classes

n is the number of the data points

We know that the number of data points is n = 20.

Next, we start searching for k so that we can get a number 2 to the k that is larger that the number of data points.

2^4=16\\2^5=32

This suggests that you should use 5 classes.
