<u></u>You would add 54+42+153=249 to find the total amount of customers from the previous week. Then you would divide 54/249= 0.2168 to find the amount of customers that used cash to total customers. The closest fraction would be about 1/5.
Answer:
The perimeter is 52
Step-by-step explanation:
The area is 36x^2 -60x+25
We set this equal to 0 to find the length and width
A= 36x^2 -60x+25
We notice that this is a perfect square trinomial
(a^2 -2ab-b^2) = (a-b)^2
let a = 6x and b=5
A=(6x-5) (6x-5)
The length and width are the same since is it a square (we know it is a square so they have to be equal)
The perimeter of a square is
P =4s
P =4 (6x-5)
Distribute the 4
= 24x -20
Let x =3
P = 24(3) -20
=72 -20
= 52
The perimeter is 52
-5x^2-8x+2
its a trinomial and its degree is 2
8.
33 = 2y + 1 + y - 1
Add the 1 and -1
Add the y and 2y
33 = 3y
11 = y
9, AQ = 2y + 1
2(11) + 1
22 + 1
23
AQ = 23
10, QX = y - 1
QX = 11 - 1
10
QX = 10
11. 62 = 3x - 4 + 3x - 4
Add -4 and -4
Then add 3x + 3x
62 = 6x
Divide 62 by 6x
x = 11 2/3
AB = 3x - 4
3 (11 2/3) - 4
3 * 11 2/3 = 35
35 - 4 = 31
AB = 31
Both sides are equal, so BC also equals 31
12. 206 = 3x - 4 + 3x - 4
206 = 6x
x = 34 1/3
AB = 3x - 4
AB = 3(34 1/3) - 4
AB = 103
Because AB and BC are the same, BC also equals 103.
