Answer:
Step-by-step explanation:
The side length AB of triangle ABC corresponds to side length of PQ of triangle PQR.
The scale factor from ABC to PQR is
The area of triangle PQR will change by centimeters square.
Since we know the area of triangle ABC to be , the area of triangle PQR
Not 100% sure but I think it’s 7
U should get Cymath for math and Socratic for everything they help a lot
Okay so first of all you have to divide the -6 that’s in the parenthesis because it’s by itself. Then when you divide it you should have k by itself and your final answer would be 2.
Hope that helps!
Let the amount of water to be mixed in be x mL. If we currently have 237 mL of 100% ammonia, and we are to add x mL of pure water (which has zero ammonia), we can add the total amounts of ammonia in the final mixture, which will have (237 + x) mL of liquid, with 75% ammonia.
(237 mL)(100%) + (x mL)(0%) = (237 + x mL)(75%)
237 = 177.75 + 0.75x
x = 79 mL
Therefore, we would need to add 79 mL of water.
