Answer:

(x+2) ^2 + (y-3)^2 = 25

Step-by-step explanation:

The equation of a circle is given by

(x-h) ^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius

(x--2) ^2 + (y-3)^2 = 5^2

(x+2) ^2 + (y-3)^2 = 25

Answer:

Step-by-step explanation:

4 quarts=1 gallon

1 quart=1/4 gallon

6 quarts 1/4×6=6/4 gallons=3/2 gallons =1 1/2 gallons

or we can say 4 quarts=1 gallon

2 quarts=1/2 gallon

(4+2=6)quarts=(1+1/2)=1 1/2 gallon.

I if the no of Girates at congtin were reduced by 63% what would be the approximate ratio of giraffes to animals in other catego

Arada [10]

Answer:

$Giraffe:Others = 3:7$

Step-by-step explanation:

<em>See Attachment for complete question</em>

For this question, we only need the data at the Congtin column.

So, we have:

$Giraffes = 124$

$Other = 108$

First, we need to reduce Giraffe by 63%.

This gives:

$New\ Giraffe = Giraffe - 63\% * Giraffe$

$New\ Giraffe = 124 - 63\% * 124$

$New\ Giraffe = 124 - 78.12$

$New\ Giraffe = 45.88$

Represent this as a ratio:

$Giraffe:Others = 45.88:108$

The closest to this ratio is 3:7.

This is shown by dividing the ratio by 15

i.e.

$Giraffe:Others = 45.88/15:108/15$

$Giraffe:Others = 3.0589:7.2$

Approximate:

$Giraffe:Others = 3:7$
