Answer:
E
Step-by-step explanation:
19) Amount of oil in = amount of oil in final product
.025(x) + .09(40-x) = .055(40) (x = 2.5% amt 40 - x = 9% amt)
x = 21.54 L of 2.5 % then 9% = 18.46 L
Answer:
12 units
Step-by-step explanation:
The radius is half of the diameter, so we need to double 6 to get 12.
3/9
24/54
35/5
35/7
Explanation:
express 1/2 with denominator 10
All you have to do is divide the 10 by two and multiply your result by the numerator.
Therefore: 10/2=5
5x1=5
numerator= 5
denominator=10
It is 15°C. The way you find out how to turn F into °C is take the number in F subtract 32 from it take that number and multiply it by .5559, then you will have your answer.
Answer:
Equation C. 5.1 + 2y + 1.2 = -2 + 2y + 8.3
Step-by-step explanation:
Equation C is the only equation in the list in which the terms that contain the unknown "y" on each side of the equal sign are identical, therefore when solving for this unknown and trying to group them on one side, they go away, leaving us with a relationship among numerical values that is always true:
5.1 + 2y + 1.2 = -2 + 2y + 8.3
5.1 + 1.2 = -2 + 8.3
6.3 = 6.3
Then this equation is true for any value of the unknown y, and y- can adopt infinite number of values, independent of which the equation will always be a true statement (giving thus infinite number of solutions).
