Can or bottle? A can will be the calculation for the surface area of a cylinder which is A= 2 \pi rh+2 \pi  r^{2} if r is the radius of the circle on the top and bottom of the can and h is the height of the can. A can is basically two circles and a big rectangle. For a bottle I don't know there are too many components and no numbers to solve for that

A square has the sides length 2k-1 units. An equilateral triangle has the sides of the length k+2 units. the square and the tria
AlladinOne [14]
I think that you assumed that:
2k - 1 = k + 2

However we can't do this, because a square has 4 sides whilst a triangle only has 3 sides. 
This means that we can say
4(2k - 1) = 3(k + 2) 

We multiply by 4 due to 4 sides of the square, and by 3 due to the 4 sides of the triangle.

Lets expand the brackets, and solve it:

4(2k - 1) = 3(k + 2)
8k -4 = 3k + 6
5k -4 = 6    ( subtract both sides by 3x to collect the x values)
5k = 10      (add both sides by 4 to get the x's alone)
k = 2           (divide both sides by 5 to get what just x is)

So k = 2 units

When Ibuprofen is given for fever to children 6 months of age up to 2 years, the usual dose is 5 milligrams (mg) per kilogram (k
Sonbull [250]

Answer:the usual dosage would be

54.55 milligrams.

Step-by-step explanation:

When Ibuprofen is given for fever to children 6 months of age up to 2 years, the usual dose is 5 milligrams (mg) per kilogram (kg) of body weight when the fever is under 102.5 degrees Fahrenheit. This means that the usual dose for a 18 month old child would be 5 milligrams (mg) per kilogram (kg) of body weight. Since the weight of the child is 24 pounds, we would covert 24 pounds to kilogram.

2.2 pounds = 1 kg

24 pounds = 24/2.2 = 10.91 kg

Therefore, the dosage would be

5 × 10.91 = 54.55 milligrams

Evaluate the expression 10-2x for the x values given below
cricket20 [7]

For this case we have the following expression:

10-2x

Let's evaluate the expression for some values of x.

We have then:

For x = 1:

10-2 (1)\\10-2\\8

For x = 2:

10-2 (2)\\10-4\\6

For x = 3:

10-2 (3)\\10-6\\4

For x = 4:

10-2 (4)\\10-8\\2

For x = 5:

10-2 (5)\\10-10\\0\\

Answer:

The value of the expression in ordered pairs is:

  • (1,8)
  • (2.6)
  • (3,4)
  • (4.2)
  • (5.0)
