Answer:
length = 20 cm
width = 9 cm
Step-by-step explanation:
perimeter = 58 cm
58cm = 2*L+2*w equation 1
L = 3w -7 equation 2
where:
L= length
w=width
so we have:
58 = 2(3w -7) +2w
58 = 6w -14 +2w
58 +14 = 8w
72 = 8w
w = 72/8
w = 9 cm = width
we have:
L = 3(9) -7 = 20 cm = length
1. squaring
2. four triangles and the square with side length "c"
3. big square (side length: a+b)
Answer:
Step-by-step explanation:
Both equations of this system are of degree one.
They are both linear as the graph of both is a line.
Answer: It should be 270 ml
Step-by-step explanation:
To find 3/8 of 720, we need to know 1/8
Divide 720 by 8, this gives you 90
Now multiply 90 by 3 to get 3/8
Answer is 270 ml
Answer:
The number of tablets that can be prepared is 3076.
Step-by-step explanation:
The total amount of active ingredients in the tablet is the sum of the amounts provided in the formula:

The percentages of each component in the formula are:
Acetaminophen:
%
Chlorpheniramine maleate:
%
Dextromethorphan hydrobromide:
%
If 1 Kg=
mg of acetaminophen is used, the needed amount of chlorpheniramine maleate would be:

Since there are 125 g = 125000 mg of chlorpheniramine maleate, there is enough of these ingredient to run the available acetaminophen out. Thus, the total amount of active ingredients that can be prepared with 1 kg of acetaminophen is:

Since each tablet weighs 342 mg, the number of tablets that can be prepared is:

Which means that 3076 tablets can be prepared and a there will be a remanent of 0.923*342 mg = 315.69 mg of active ingredients.
