Krishna wants to make trail mix made up of almonds, chocolate covered coffee beans, and peanuts. he wants to mix one part almonds, two parts coffee beans, and three parts of peanuts. almonds cost $12 per pound, coffee beans cost $9 per pound, and peanuts cost $5 per pound. carlos has $30 to spend on the trail mix. how many pounds of trail mix he can make?

The trail mix has :

pounds of almonds

pounds of coffee beans

2 pounds of peanuts.

Given is :

1 part almond

2 parts coffee beans

3 parts peanuts

This can be written as 1:2:3

Cost of almond = 12 per pound

Cost of coffee beans = 9 per pound

Cost of peanuts = 5 per pound

Let x represents almonds

Let y represents coffee beans

Let z represent peanuts

Given is : Carlos has $30 to spend on the trail mix.

         .... (1)

Substituting in equation 1

pounds     (almonds)

Now, y = 2x, so y = pounds (coffee beans)

And z = 3x, so z = 2 pounds (peanuts)

Now checking the amounts:

Almonds : dollars

Coffee beans : dollars

Peanuts : dollars

Total amount = dollars

Therefore, the trail mix has :

pounds of almonds

pounds of coffee beans

2 pounds of peanuts.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
