Answer: 28 Inches

Step-by-step explanation:

First draw a square for this. Since the kitchen tile is a square, we only need one side of the shape which in this case it 7in. Then you take this number and input it on all sides. You should have 7in on all sides. Next you write this equation: 7+7+7+7 or 7x4. This will then give you the answer 28. So, the perimeter of the kitchen tile is 28 inches.

How many grams of 0.5% hydrocortisone cream must be mixed with 180 g of 2.5 % cream to make a 1 % w/w hydrocortisone cream? HINT

Sophie [7]

Answer:

We need 540 grams of 0.5% hydrocortisone cream

Step-by-step explanation:

Lets call x the amount of grams needed. This means that the combined cream will have 180+x grams. We want x such that

x * 0.005 + 180*0.025 = (180+x)*0.01

Hence

0.005x + 4.5 = 1,8+0.01x

Lets put the x in the same side and take common factor

4.5-1.8 = 0.01x-0.005x

2.7 = (0.01-0.005)x = 0.005x

As a result

x = 2.7*0.005 = 540

We need 540 grams.
