Answer:
432 liters
Step-by-step explanation:
Because the container was already 4/9 full, 240 liters is 5/9 of the whole.
1. Convert 5/9 to a decimal and then a percent by dividing the fraction and then multiplying by 100:
5/9 = 0.5556 = 55.56%
2. To determine what number 240 is 55.56% of, write the equation like this:
0.5556x = 240
(In which x = the number you are solving for)
3. Divide both sides of the equation by 0.5556 to isolate the variable.
x =
x = 432 (Don't forget the unit, liters)
4. To check your work, make sure that 240 is 5/9 (55.56%) of 432:
432 × 0.5556 = 240
(Note: Because the fraction converts to a repeating decimal, I had to round it. This means the answer is a very small decimal off from the actual answer that I put.)
Answer:
x=3.5
Step-by-step explanation:
You can find x by finding the hypotenuse of that triangle, which is the leg of the other triangle. Find the value of the leg first:
You can use the sine ratio to find the leg. This is because and we have the hypotenuse for that triangle and we need to find the side opposite the given angle, 45°. Insert values:
Solve for x. Multiply both sides by 7:
Enter the value into a calculator:
The leg is 4.9. Use this to solve for the next x. Use the sine ratio for the same reason. Insert values:
Solve for x. Multiply both sides by 4.9:
Insert into a calculator:
Finito.
