It would be $12.45,because it's going down by .85 cents so you would .85 times 3 which would equal $2.55, so you would subtract $15 by $2.55 which would equal the answer $12.45.

SOMEBODY PLEASE HELP ME!!
notsponge [240]

Answer:

60 square units; 40 units

Step-by-step explanation:

to find the missing side you use the pythagorean theorem

a^2 + b^2 = c^2

8^2 + b^2 = 17^2

64 + b^2 = 289

b^2 = 225

b = 15

area is l*h*1/2

15 * 8 * 1/2 = 60 square units

perimeter is adding them all

15 + 8 + 17 = 40 units

You blow a bubble in the shape of a sphere. It has a radius of 5 inches. Which choice is closest to its surface area? Use 3.14 t
vredina [299]
The formula to find the surface area of a circle is: pi x radius², so if we square the radius the answer would be 25, then we multiply that by 3.14 and the answer would be around 78.5, so the answer is 78.5.

What two numbers multiply to negative 8 but add to negative 7
Amiraneli [1.4K]
Let "a" and "b" be the two numbers
So a*b=-8 and a+b=-7
Therefore S=-7 and P=-8
Using (x^2)-S+P=0 => (x^2)-(-7)+(-8)=0 => (x^2)+7-8=0
By factorizing we get (x+8)(x-1)=0
So a can be either -8 or 1 and b can be 1 or -8 
Meaning that the two numbers are -8 and 1.
