Answer: A is 8. B is the square root of 128.
Step-by-step explanation: Nah.
Answer:
Quantity of solution B required is 300 ml
Step-by-step explanation:
Let "a" be quantity of solution A required
Let "b" be quantity of solution B required
We are given Solution A is 19% alcohol and Solution B is 14% alcohol and that the resulting mixture has 156 milliliters of pure alcohol
Thus;
0.19a + 0.14b = 156 - - - (eq 1)
Also, He uses twice as much Solution A as Solution B.
Thus;
a = 2b
Putting 2b for a in eq 1 gives;
0.19(2b) + 0.14b = 156
0.38b + 0.14b = 156
0.52b = 156
b = 156/0.52
b = 300 ml
Quantity of solution B required is 300 ml
Represent even numbers as "2n" since each is a multiple of 2.
Represent odd numbers as "2n+1" since each is one more than an even.
-----------------
Your problem:
smaller # : 2n
larger #: 2n+2
-------------------
EQUATION:
2n+2 + 3(2n) = 234
8n = 232
n = 29
---------
smaller = 2*29 = 58
larger = 2n+2 = 60
Answer:
no
Step-by-step explanation:
Example:
- 9 is an odd number, but 9 can be divided by 3, so 9 is not a prime number.
- 49 is an odd number, but 49 can be divided by 7, so 49 is not a prime number.
