2y+4=2(y+2)
2y+4=2y+4
4=4
so the answer is all real numbers or infinite solutions
Answer:
4 litres of 12% solution
2 litre of 24% solution
Step-by-step explanation:
Let the 12% solution = l
Let the 24% solution = h
Dimitri needs a total of 6 litres of both :
l + h = 6 - - - - - - - - (1)
He needs a mixture of both volumes of both to give a 16% volume
12%l + 24%h = 16% * 6
0.12l + 0.24h = 0.96 ----(2)
From (1)
l + h = 6;
l = 6 - h
Substitute l =6-h into (2)
0.12(6 - h) + 0.24h = 0.96
0.72 - 0.12h + 0.24h = 0.96
0.72 + 0.12h = 0.96
0.12h = 0.96 - 0.72
0.12h = 0.24
h = 0.24 / 0.12
h = 2
From ;
l = 6 - h
l = 6 - 2
l = 4
Hello!
To find the volume of a rectangular prism you use the equation
V = lhw
v is volume
l is length
h is height
w is width
Put in the values you know
180 = 6 * 5 * w
Divide both sides by 6
30 = 5 * w
Divide both sides by 5
6 = w
Answer is 6cm
Hope this helps!
We have that
8=2*2*2
108=2*2*3*3*3
then
√(8/108)=√(2*2*2)/(2*2*3*3*3)=√(2)/(3*3*3)=(1/3)*√(2/3)
the answer is (1/3)*√(2/3)
Answer:
C
Step-by-step explanation:
Area of the triangle is cm^2 which makes A and D not true.
Formula
Area = 1/2 * b * h
b = 7
h = 5
Area = 1/2 * 7 * 5
Area = 1/2 35
Area = 17.5 cm^2
