Answer:

C. (4,28)

Step-by-step explanation:

When y = 8x - 4 ; x = 4

when u substitute x in the equation

the value of y = 28

y = (8 x 4) - 4

= 32 - 4

= <u>2</u><u>8</u><u>.</u>

As coordinates it would be (x,y) = <u>( 4,28 )</u>

Dennis has three identical ​cylinders​ filled with water. How many ​cones should he be able to fill with the water if the cones
Brut [27]

Answer:

3 cylinder will fill 9 cones with water

Step-by-step explanation:

This problem bothers on mensuration of slides, cone and cylinder

We know that the

Volume of a cylinder = πr²h

Volume of a cone = 1/3(πr²h)

Given that both cylinder and cone has same height and radius

From the given expression we can deduce that the cone is 3 times smaller than the cylinder in volume

So if 1 cylinder will fill 3 cones

Then 3 cylinders will fill x cones

By cross multiplication we have

x= 3*3cones

x= 9 cones

Hence 3 cylinder will fill 9 cones with water

 so approximately 2.22 kilograms per pound

 divide price per pound by kilometers per pound

1.44 / 2.22 = 0.648

 round to 0.65, so it costs $0.65 per kilogram

Quantity of Jackets Price (in whole dollars) Total Revenue Marginal Revenue Total Cost Marginal Cost Profit (or loss) 0 20 1 20
KonstantinChe [14]

Answer:

18 dollars

Step-by-step explanation:

Marginal cost can be defined as the additional cost to produce every additional unit of a certain good. In mathematical terms;

Marginal cost = change in cost / change in quantity

For seven jackets, we have to find the difference between the cost of seven jackets and the cost of six jackets as follows

$101 - $83 = $18

Since the change in quantity is one, our marginal cost comes to $18.
