1) in one minute for first wiil be 1/20
the other 1/30, it means that A paint in one minute 1/20 and B 1/30 then A+B in one minute 1/20 + 1/30 = 3+2/60 = 5 / 60, 5/60 = 1/12
if in one min they make 1/12 then in 12 min they paint all the wall
Answer:
a. is 1 and b is 2 and c is 3 I did it in algebra pay attention in class
280 eels
92 + 56 + 52 = 200
eel = 56/200
56 *5 x
----- = --------
200 *5 1000
56(5) = 280 x = 280
56/200 = 7/25
7/25 = 280/1000
Answer:

Step-by-step explanation:
The given sequence is 2, 4, 6, ....
We need to write an explicit formula for
. The firts term is 2, second term is 4 and third term is 6 and so on.
Each term is 2 greater than the term before it. Thus we can write it as follows :

Where
n = 1,2,3....
Hence, the explicit formula is
.
Each shape has a different formula for area. rectangles and parallelograms share the same formula, A=bh
Trapezoids formula is A= 1/2(b1 + b2)h
Triangles formula is A = 1/2bh
In all of these formulas, A means area, and h means the height of the shape. In the formulas for triangles and rectangles/parallelograms, b stands for the length of the base of the shape.
In the trapezoids formula, b1 means base 1 and b2 means base two, as a trapezoid has two different bases.
After finding all of the variables for the formula of the shape you're solving for, plug all the numbers into your missing variables, and solve as normal.
