Answer:
Scientist B
Step-by-step explanation:
1 kg = 2.2 lbs
1L = 2.11 pints
So let's convert Scientist B's data.
3.0lbs salt = 3.0/2.2 = 1.36kg
6 pints water = 6/2.11 = 2.84L water
Scientist A
1kg salt
3.0L water
We now figure out the concentration of salt in water.
Scientist A Scientist B
1kg/3.0L = .33kg/L 1.36kg/2.84L = .48kg/L
So scientist B had a more concentrated solution.
Answer:
x=9
z=73
Step-by-step explanation:
Angle 107 and 8x+35 are vertical angles, so they are equal
107 = 8x+35
Subtract 35 from each side
107-35 = 8x+35
72 = 8x
Divide by 8
72/8 = 8x/8
9 =x
We also know that 107 and z are supplementary angles since they form a straight line. This means they add to 180 degrees
107+z = 180
Subtract 107 from each side
107-107+z=180-107
z =73
Answer:
The value of x is 20 degrees.
Step-by-step explanation:
The three angles of a triangle must equal 180 degrees.
100 + 40 + 2x = 140 + 2x
180 - 140 = 40 (goal)
2(x) = 40
2(20) = 40
A) 20 degrees
A measurement that closely agrees with an accepted value is best described as a numerical
