Answer:

(x + 7)² + (y - 8)² = 1

Step-by-step explanation:

(x - h)² + (y - k)² = r²

h = - 7, k = 8, r = 1

(x -(-7))² + (y - 8)² = 1²

(x + 7)² + (y - 8)² = 1

What is the ratio between 3,600:4,950
grin007 [14]

Answer:

8:11

Step-by-step explanation:

That is a ratio, but you can further simplify by dividing each side of the ratio by the same numbers. Start with basic ones you know, for example 50 will go into both evenly.

3600/50:4950/50

72:99

Keep dividing each side until you can't make even numbers.

72/9:99/9

8:11

17.5 how to make this into a fraction
BARSIC [14]
Take the .5 of the 17.5 and convert it to a fractin.
we know .5 is equal to 50% or 1/2 

now we have a mixed number  17 \frac{1}{2}

in order to convert it into an improper fraction you need to multiply the whole number by the denominator and then add the numerator all while keeping the denominator constant. 

W \frac{N}{D} =  \frac{(W*D)+N}{D}

so 17 \frac{1}{2}= \frac{(17*2)+1}{2}= \frac{35}{2}
