D. The water evaporates and the salt remains in the beaker.
When a liquid is boiled the liquid evaporates, while the minerals settle.
The area of a triangle is represented by 1/2 x B x H, where B = base, H = height.
In this equation, B = 4, H = 6
1/2 x 4 x 6 = 12 in^2
Answer:
70 degrees
Step-by-step explanation:
In the parallelogram KLMN, the sum of the adjacent angle is 180 degrees
Hence;
m<K + m<L = 180
110 + m<L = 180
m<L = 180-110
m<L = 70degrees
Hence the measure of m<l is 70 degrees
Solving the equation:
2x+1+3=0
2x+4=0
2x+4-4=0-4
2x=-4
2x/2=-4/2
x=-2
Therefore, the student that concluded x=4 is incorrect.
Let assume
X for ice cream cones
Y for sundaes
X+Y=172
X=172-Y……..*
1.10X+2.35Y=294.20
Substitute * in the above equation
1.10(172-Y)+2.35Y=294.20
189.2-1.10Y+2.35Y=294.20
1.25Y=294.20-189.2
1.25Y=105 divide both sides by 1.25
Y=84
The substitute Y value in * equation
X=172-84
X=88
Therefore
88 ice cream cones and 84 sundaes were sold!!
