75% of salmon pass through a single dam unharmed. By what percent does the number of salmon decrease when passing through a single dam?

Answers

Answer 1

Answer:

100%-75%= 25%

...........

Answer 2

The percentage that represents the number of salmon decrease when passing through a single dam will be 25%.

What is the percentage?

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

75% of salmon pass through a single dam unharmed.

The percent that represents the number of salmon decrease when passing through a single dam will be given as,

⇒ 100% - 75%

⇒ 25%

The percentage that represents the number of salmon decrease when passing through a single dam will be 25%.

5. Each pair of polygons below are similar. Show your work! Solve for x:

Answers

Since they are similar, you need to find the ratio of similarity (I made up the term, there is probably a correct one that I can’t remember).

If you divide 16/40, you’ll find that that ratio is 2.5. So then you just multiply 16 x 2.5. You’ll get 18.

18 is the length of the top of the trapezoid.

You set 18=2x+4 and solve it algebraically. Subtract 4 from both sides.

14=2x
Divide by 2 and x=7

(You can also check that the ratio is right by 16/18 is the same decimal value as 40/45. You’ll get .88888...)

It takes 45 min for Faucet A to fill a tank, and it takes Faucet B 63 min. How many minutes will it take the two faucets to fill the tank together?

Answers

Answer:

the total minutes taken together is 26.25 minutes

Step-by-step explanation:

The computation of the number of minutes that required to fill the tank together is shown below:

[tex]\frac{1}{45} + \frac{1}{63} = \frac{1}{x}\\\\\frac{7 + 5 }{315} = \frac{1}{x} \\\\\frac{12}{315} = \frac{1}{x} \\\\12x = 315\\x = 26.25[/tex]minutes

Hence, the total minutes taken together is 26.25 minutes
