I found a place that will give me 20% discount if I spend over $50.My bill $75.How much money will I save? What is my final bill

kenny6666 [7]

Answer:

You will save: $15

Total cost: $60

Step-by-step explanation:

First turn the percent into a decimal.

To do so move the . over to the left twice.

20% - .20

Now multiply 75 by .20

75 x .20 = 15

So you will save $15

Now subtract 15 from 75

75 - 15 = 60

180:210 is equivilant to

Dafna11 [192]

What you will need to do here is take 180 and divide it by 210 which will give you .<span>85714285714

And if you need to round that to the nearest tenth you will get .9 </span>

If, P(x,y) is a point on the unit circle determined by real number δ, then tanδ = what

Lisa [10]

$\bf sin(\theta)=\cfrac{opposite}{hypotenuse}
=\cfrac{y}{r}
=\cfrac{1}{csc(\theta)}
\\ \quad \\\\
% cosine
cos(\theta)=\cfrac{adjacent}{hypotenuse}
=\cfrac{x}{r}
=\cfrac{1}{sec(\theta)}
\\ \quad \\\\
% tangent
tan(\theta)=\cfrac{opposite}{adjacent}
=\cfrac{y}{x}
=\cfrac{sin(\theta)}{cos(\theta)}$

$\bf cot(\theta)=\cfrac{adjacent}{opposite}
=\cfrac{x}{y}
=\cfrac{cos(\theta)}{sin(\theta)}
\\ \quad \\\\
% cosecant
csc(\theta)=\cfrac{hypotenuse}{opposite}
=\cfrac{r}{y}
=\cfrac{1}{sin(\theta)}
\\ \quad \\\\
% secant
sec(\theta)=\cfrac{hypotenuse}{adjacent}
=\cfrac{r}{x}
=\cfrac{1}{cos(\theta)}\\\\

P(x,y)\implies \delta\qquad tan(\delta)=\cfrac{y}{x}$
