Answer:
D. The value of the 6 in 364 is 10 times the value of the 6 in 346
Step-by-step explanation:
The digit 6 in 364 is ten times greater than the 6 in 346.
60 is 10 times greater than 6
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
12/9 reduced in simplest form would be 4/3 or 1 1/3. You can pick which one you want to do :). They are both the same thing just one is an improper fraction and the other is a mixed number. I got this answer by dividing both the top and the bottom (The denominator and the numerator) by three.
The area of the rectangle is length times width, that is
A = L*W
The problem requires the width so
W = A/L
Given that A = 437 sq. cm and L = 19 cm, therefore
W = 437/19 = 23 cm
That is the answer.
