Answer: d. 29%

Step-by-step explanation:

The mixture of the two concentrations should equal a concentration that is between the concentration percentages of the two solutions.

This is because the lower concentration percentage will pull the higher one down while the higher concentration will pull the lower one up. It will not be possible to get a mixture concentration that is lower than the lower concentrated acid or higher than the higher concentration acid.

Mixture concentration must be between 15% and 25%.

Option D at 29% is therefore not possible.

A car that travels 20 miles in LaTeX: \frac{1}{2}1 2 hour at constant speed is traveling at the same speed as a car that travels
charle [14.2K]

Answer:

10 miles per 1/4 hour

40 miles per hour

Step-by-step explanation:

Given that:

A car travels 20 miles in 1/2 hour

Miles traveled per hour :

(20 * 2) / 1 = 40 miles per hour

Mile traveled in 1/4 hour :

Distance = speed * time

Distance = 40 mph * 1/4 = 10 miles per 1/4 hour

Car traveling 30 miles in 3/4 hours

(30 * 4) /3 = 120 / 3 = 40 miles per hour

Distance = 40 mph * 1/4 = 10 miles per 1/4 hour

malfutka [58]

Answer:

12 sandwiches

Step-by-step explanation:

Make a proportion

He can make 6 sandwiches with 3 tomatoes, and x sandwiches with 6 tomatoes

6/3=x/6

Multiply both sides by 6 to isolate the variable, x

6*6/3=x/6*6

12=x

So, with 6 tomatoes, he can make 12 sandwiches
