You can write any decimal as a precent by moving the decimal 2 places to the right so
0.51 = 51%
5.1% < 51%
5.1% < 0.51
or, any precent can be written as a decimal by moving the decimal points two point to the left so
5.1% = 0.051
0.051 < 0.51
5.1% < 0.51
Lets look at the info we have:-
6 friends
Pay $90 and receive $42 in change.
Question:-
How much does each friend pay?
To answer this first we nee to find out how much they paed in total. lets do that 1st:-
90 - 42 = 48
They paid $48 for the gift.
CHECK OUR WORK:-
48 + 42 = 90
We were RIGHT!!
Now lets divide to find out how much each person paid:-
48 ÷ 6 = 8
Each friend pays $8.
CHECK OUR WORK:-
8 × 6 = 48
We were RIGHT!!
So, each friend pays $8 for the gift.
Hope I helped ya!! xD
(0,2),(-2,-1),(2,5)
-3x+2y=2
+3x +3x
2y/2=3x+2/2
y=1 1/2x+2
Plug in numbers for x then solve for y
Answer:
The equations have the same mathematical form:
S = A + V0 t - 1/2 g t^2
They are both quadratic equations in one variable (t here)
This equation expresses the distance traveled by an object in time t in the vertical direction - it does not necessarily refer to a graph
In the other equation, y can be considered a vertical coordinate equation on a graph and x would be the horizontal coordinate
Note that in one equation 3 terms are necessary to describe the displacement of an object in one direction
In the other 2 terms in the x-direction describe the displacement in the other or y-direction
Answer:
Number of workers = 20.
Step-by-step explanation:
p = - 4w^2 + 160 w
We need to find the value of w when p is a maximum.
We need to convert the equation to vertex form:
p = -4w^2 + 160w
p = -4(x^2 - 40w)
p = -4 [ (x - 20)^2 - 400]
p = -4(x - 20)^2 + 1600.
So the vertex is at (20 , 1600)
The maximum profit is 1600 and the number of workers = 20.
