snow_lady [41]

Answer:

$20196

Step-by-step explanation:

12 × 9 × 6 = 648 cubic feet ( volume of slab )

3 feet to a yard

So 648 ÷ 3 = 216

Multiply this by 1.1 to add an extra 10%

237.6 Cubic Yards Needed

$85 × 237.6 = $ 20196

Answer:

Divide the weight of the bag by 2.

Step-by-step explanation:

Every time we divide the weight of bags by 2 we always get the number of marbles in this situation.

For example, in the first one:

Weight of bag is 20

Number of marbles is 10

20/10 = 2 or 20 / 2 = 10

On bag number 5 the weight is 100 grams (Add 20 every time)

100/2 = 50

The number of marbles in a bag that weighs 100 grams is 50.

50 marbles

Find the gradient from this equation 2x + 5y = 1​
slega [8]

Answer:-2/5

Step-by-step explanation:

Now the above equation can be rewritten as 5y= -2x+1

Dividing this expression through by 5, we have 5y/5 = -2x/5 + 1/5

y= (-2/5)x + 1/5

Comparing with the general equation of a line;

y = mx + c; m= gradient; C= constant along the y-axis

m= -2/5
