Answer:
725.95
Step-by-step explanation:
If you multiply 129.95*5. You get 649.75, but you have to add 76.20 from the delivery and you get 725.95
Hope this helps =)
Answer: V≈5.21 cm³
Step-by-step explanation:
To find the volume of a rectangular prism, you multiply the length, width and height.

Since we were given the length, width and height, we can directly multiply them together.
[multiply]

Now, we know that the volume is approximately 5.21 cm³ or 125/24 cm³.
The original price was $500
First we find 15% of what is $75
15/100 x N =$75
n = $7500/15
n = $500
Answer:
See below
Step-by-step explanation:
then f(x)=0 if x<0 and f(x)=x if x≥0.
When x→-∞, f is the constant function zero, therefore
. When x→∞, f(x)=x and x grows indefinitely. Thus 
f is differentiable if x≠0. If x>0, f'(x)=1 (the derivative of f(x)=x) and if x<0, f'(0)=0 (the derivative of the constant zero). In x=0, the right-hand derivative is 1, but the left-hand derivative is 0, hence f'(0) does not exist,
f'(x)>0 for all x>0. Therefore f(x) is strictly increasing on the inverval (0,∞).
Because the angles in all triangles must add up to 180 degrees the third angle measurement will be 90 degrees. Since the angle is 90 degrees it is automatically a right triangle.
