Marcia dissolved 1 kg of salt in 3 litres of water.
Bobby dissolves 2 pounds of salt in 7 pints of water
2.11 pints = 1 litre
7 pints = 7/2.11
= 3.32 litre
1 pound =0.45 kg
2 pound = o.45*2 kg
= 0.9 kg
So we find that Bobby is dissolving 0.9kg of salt in 3.32 litre of water
Marcia is dissolving 1 kg of salt in 3 litres of water.
So it can be said that Marcia made a more concentrated salt solution.
is the proportion of tires that are defective so
so we would expect around 1600 tires to be defective
Answer:
C
Step-by-step explanation:
Under a reflection in the line y = x
a point (x, y ) → (y, x ) , thus
P(- 1, 6 ) → P'(6, - 1 ) → C
This triangle is an equilateral, meaning that all the sides of the triangle are equal. We know this because all the angles of triangle are marked equal. Keeping this in mind, you can then set two of the sides equal to each other and solve for x.
3x+6=5x
6=5x-3x
6=2x
6/2=x
3=x
The answer is x=3
Answer
The answer to this equation would be 64. '^' just means multiplied by. It has the same mathematical definition as the multiplication sign.
Step-by-step explanation:
USING PEMDAS (NO PARENTHESES)
4 x 2 x 2 x 4
8 x 2 x 4
16 x 4
64
USING PEMDAS (WITH PARENTHESES)
(4 x 2) x (2 x 4)
(8) x (2 x 4)
(8) x (8)
64
