Answer:
D
Step-by-step explanation:
I took the quiz and got it right.
Also, the equation is y > x/2 - 3
The answers are: 4.5 g and 56.25 g respectively.
Since the first type of measurement in this question is weight or mass, I'll suppose that the percentage concentration is % mass/mass. For that type of concentration measurement, just multiply the percentage by the total mass to get the mass of the wanted material.
So 150 g * 3% = 150 g * 0.03 = 4.5g
For the 8% solution with the same amount of dry substance, use the ratio of percentages, multiplied by the mass of the first solution to get the wanted amount of new solution:
3/8 * 150 g = 56.35 g
14 and the remainder is 3
Answer:
2/8 of a book in an hour
Step-by-step explanation:
1/2 an hour times 2 is 1 ( an hour)
1/8 times 2 is 2/8
she can read 2/8 of a book in an hour
Answer:
see explanation
Step-by-step explanation:
The n th term of a geometric sequence is
= a
where a is the first term and r the common ratio
Given 
= 
and r = 
, then
a 
= , that is
=
= ( cross- multiply )
32a = 2048 ( divide both sides by 32 )
a = 64 ← first term
Thus the explicit formula is
= 64
