Answer:

$(x+15)^2+(y-11)^2=4$

Step-by-step explanation:

<u><em>The question is</em></u>

How do you write an equation for a circle with center (-15,11) and radius 2?

we know that

The equation of a circle in center radius form is given by

$(x-h)^2+(y-k)^2=r^2$

where

(h,k) is the center of the circle

r is the radius of the circle

substitute the given vales

$(x+15)^2+(y-11)^2=2^2$

$(x+15)^2+(y-11)^2=4$

Answer:

a) 300m

b) 15 miles

Step-by-step explanation:

a) 1 : 30 000

= 1x 30 000

= 30 000cm

= 30 000cm/ 100 Representing in metres

= 300m

b) 1 : 6

= 1x 2.5 : 6x 2.5

= 2.5 : 15

= 15 miles

While on vacation Craig bought a pair of sunglasses for $15.98 for $7.99 5 postcards and a beach towel the beach towel cost 0.50

NISA [10]

Answer:

$0.79.

Step-by-step explanation:

Let T= The price of beach towel,

P = The cost of each postcard.

S = The cost of sunglasses.

H = The cost of hat.

We have been given that while on vacation Craig bought a pair of sunglasses for $15.98. The beach towel cost 0.50 cents more than half the price of sunglasses.

We can set this information in an equation as:

$T=\frac{15.98}{2}+0.50$

$T=7.99+0.50$

$T=8.49$

We are told that Craig gave the cashier $40 and got 3.59 change and each postcard cost the same. So we can set this information in an equation as:

$T+5P+S+H=40-3.59$

Let us substitute our given values.

$8.49+5P+15.98+7.99=40-3.59$

Let us combine like terms.

$32.46+5P=36.41$

Let us subtract 32.46 from both sides of our equation.

$32.46-32.46+5P=36.41-32.46$

$5P=3.95$

Let us divide both sides of our equation by 5.

$\frac{5P}{5}=\frac{3.95}{5}$

$P=0.79$

Therefore, each postcard costs $0.79.
