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.
Answer:
292 cm²
Step-by-step explanation:
the area = 2×(8×6 +8×7 + 6×7)
= 2×(48+56+42)
= 2×146
= 292
Answer:
D=1
Step-by-step explanation:
g(x)=x³-9x²+27x-25
g(2)=(2)³-9(2)²+27(2)-25
=8-36+54-25
=1
Answer:
Correct option is the third option:
6*3 - 4+3^2
Answer:
-20xy -8y+26
Step-by-step explanation
First Multiply 2 by 3.
6 + 10 x 2 - 4 x (2y) - 20xy
Then Multiply 10 by 2.
6+20-4x(2y)-20xy
After that Multiply 2 by -4.
6+20-8y-20xy
Lastly add 6 and 20.
26 -8y -20xy
