Answer:
m= -2
b = 3
Step-by-step explanation:
Take two points from line.
(0,3) and (1,1)
now slope(m) = (1-3)/(1-0)
m = -2
now
y = mx+b
or, 3 = -2×0+b
or, 3 = 0+b
so, b = 3
First of all, you have to find the area of both triangles:
![\frac{bh}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bbh%7D%7B2%7D%20)
![\frac{4*4}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%2A4%7D%7B2%7D%20)
Or just 16 because there are 2 of the same triangles.
Now you have to find the area of the 3 rectangles.
The two that are in the front are 4*3 (l*h) or 12*2 (because there are 2 congruent rectangles. The area of those rectangles is 24 square mm.
Now you find the area of the back rectangle:
5.7*3 = 17.1
Finally, you add all the found numbers to figure out the surface area.
17.1 + 16 + 24 = 57.1 square millimeters.

Answer:
300 lbs
Step-by-step explanation:
We know that Larry bench pressed 200 lbs last week, and that he is supposed to increase by 15%. We know that any number times one is that same numbers. That means a number that is increaseing has to be greater than 1. So, we have to convert 15% into a decimal. That is 0.15. That plus one is 1.15. Now we just have to multiply 1.15 with 200. We get 300.

Answer:
Step-by-step explanation:
Volume of a right circular cone can be found using the equation
where
- r is the radius of the cone
- h is the height of the cone
- pi is the π constant
Since r=4ft, we can model the volume of the water in the cone in terms of the height as
=
