Bad White [126]3 years ago

Answer:

  y = -4/5

Step-by-step explanation:

Both coordinates are negative in the 3rd quadrant. The value of y is the other leg of the right triangle with hypotenuse 1. The Pythagorean theorem is helpful.

  y = -√(1 -(-3/5)^2) = -√(1 -9/25) = -√(16/25)

  y = -4/5

PLEASE ANSWER! I AM GIVING OUT LOTS OF POINTS! IM DESPERATE! Alyssa claims that dividing by 4/5 is he same thing as multiplying
BigorU [14]
No, she is NOT correct because for example, if 20 is multiplied by 4/5 then it first has to be multiplied by 4 then divided by 5 (even though you can use cross multiplying) EX: 20×4=80/5=16

Rewrite the expression c + 0.25c using fractions instead of decimal numbers.
gogolik [260]

Answer:

\huge\boxed{\frac{5c}{4},\ or\ c+\frac{1}{4}c,\ or\ c+\frac{c}{4}}

Step-by-step explanation:

The decimal 0.25 can simply be converted into a fraction by putting it over 100.  

0.25 = \frac{25}{100}

Then, simply divide both the numerator and denominator by 25 to get

\frac{25/25}{100/25}, or \frac{1}{4}

Hope it helps :)
