What about it? What is the question?
The answer is;
Flame test is a qualitative test".
Flame test is performed for detecting metals in a compound and metals are detected by the color of the flame, and flame color identifies that which metal is this. so this is a qualitative test, different types of metals shows different color of flames.
Question A
take $100.80 divide it by 35 which would equal 2.88
so round that up for 3.0 for the closest answer
Question B
take 49.2 and divide it by 6 which would equal 8.2
so round it to the nearest number which would be 8.0
Question C
take 0.78 and divide it by 20L which would equal 0.039
so round that up to the closest number which would be 0.04L
Answer:
10: 12 units^2 11: 33 units^2
Step-by-step explanation:
10:
Divide into square and 2 triangles (for simplicity)
square=9
one triangle=3/2
both triangles combined=3
9+3=12
11:
divide into 2 triangles
top triangle: height= 4, base=6
bottom triangle: height= 7, base=6
top=12
bottom=21
Add, 33.
The area formula for a rectangle = Length x Width
Let length = L and width = W.
We also know that the length is 3 yards longer than twice it's width.
SO this means L = 3 PLUS 2 times W
L = 3 + 2W
Now plug that into the area formula and we get:
Area = (3 + 2W) x W
You'll need to multiply everything in the brackets by W.
So what would (3 + 2W)x W = ?
