Answer: A, 8125
Step-by-step explanation:
3,725 + 2800 + 700 + 900
3725 + 2800 = 6525
700 + 900 = 1600
6525 + 1600 = 8125
Answer:
x = 1±2i
Step-by-step explanation:
(x - 1)^2 = -4.
Take the square root of each side
sqrt( (x - 1)^2) = sqrt(-4)
Sqrt(ab) = sqrt(a)sqrt(b)
We know the sqrt(4) = 2 and the sqrt(-1) = ±i
x-1 = ±2i
Add 1 to each side
x-1+1 = 1±2i
x = 1±2i
Answer:
The answer is 4 liters.
Step-by-step explanation:
We want a final 25% solution, which means that the solvent should constitute 25 percent of all the liters of solution.
Let us call 
the litres of 40% solution, so when they are added to the 12 litres of 20% solution, the total litres of the new solution are:
of these liters, 25% must be the solvent:
Now for the 40% solution, the liters of the solvent are 
, and for the 20% liter solution, the liters of solve are 
liters. Thus the total liters 
of the solvent are
Therefore
Answer:
△KNP ≅ △GHB
△NPK ≅ △HBG
Step-by-step explanation:
Given: △PKN≅△BGH
This means two triangles PKN and BGH are congruent. Congruent triangles havecongruent corresponding parts.
So,
and corresponding vertices
Hence,
A. Triangle KNP is congruent to triangle GHB - true
B. Triangle KPN is congruent to triangle GBH - false
C. Triangle NKP is congruent to triangle HGB - false
D. Triangle NPK is congruent to triangle HBG - true
