The ordered pairs in the table below represent a linear function.

Lilit [14]

Answer:

The slope is 2

Step-by-step explanation:

Given

x y

2 3

5 9

Required

Determine the slope

First, we have:

$(x_1,y_1) = (2,3)$

$(x_2,y_2) = (5,9)$

The slope is then calculated as:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

This gives:

$m = \frac{9-3}{5-2}$

$m = \frac{6}{3}$

$m =2$

<em>Hence, the slope is 2.</em>

Paul needs 3 7/8 yards of fabric to make a tablecloth. How many tableclothes can he make from 38 3/4 yard of fabric

Leviafan [203]

First turn them into improper fractions to make things easier: 31/8 and 155/4.
You would then do 155/4 divided by 31/8, and with the same-change-flip, do 155/4 times 8/31, which is 10

Total surface area of a cube is 1014cm^2. It's volume will be :

Karolina [17]

Answer:

Option A (2197 cm³)

Step-by-step explanation:

For a cube with length of each side "a" , it's

Total Surface Area = 6a²
Volume = a³

_____________________________________________

According to the question ,

Total Surface Area = 1014 cm²

Let the length of each side of cube be 'a'.

Using the formula ,

$6a^{2} =1014$

$=> a^{2} =\frac{1014}{6} = 169$

$=> a = \sqrt{169} = +13 \: or -13$

But length can't be negative . So , length of each side = 13 cm

∴ Volume of cube = 13³ = 2197 cm³
