Sally started her own dog walking business. She charges $3.00 per hour per dog. A neighbor down the street had Sally walk he golden retriever for an hour and a half and her chocolate lab for 45 minutes. Calculate how much Sally's neighbor owes her for walking both dogs. Pls show your work.
a. $5.25
b. $7.00
c. $7.50
d. $6.75

It is A

Step-by-step explanation:

First, start with a minimum of $3 because she walked the golden retriever for one hour.

Then, get 75% of $3, which is $2.25 for the chocolate lab.

Last, add $2.25 to $3 and you get $5.25, the answer.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
