3 0

Answer:

7/8

Step-by-step explanation:

Start by finding a common denominator. In this case you can turn the 4 into an 8 by multiplying by 2 but you have to do the same to the 3

2(3/4)= 6/8

Step 2: Add 6/8 + 1/8

6/8+1/8= 7/8

(Free points)<br><br>Factorise x³ + 216y³ + 8z³ - 36xyz

Nadusha1986 [10]

Answer:

[x+6y+2z][x²+(6y)²+(2z)²-6xy-12yz-2xz]

Step-by-step explanation:

x³+216y³+8z³-36xyz

x³+(6y)³+(2z)³-3×6×2×xyz

As we know

a³+b³+c³-3abc=(a+b+c)(a²+b²+c²-ab-bc-ca)

Let a=x

b=6y

c=2z

Now.

[x+6y+2z][(x²+(6y)²+(2z)²-x×6y-6y×2z-x×2z]

[x+6y+2z][x²+(6y)²+(2z)²-6xy-12yz-2xz]

A local car wash is open 8 hours each day. It uses 1/3 of a container of wax for each car. The car wash waxes an average of 8 1/

sweet-ann [11.9K]

Answer:

22.67 containers.

Step-by-step explanation:

The number of cars washed is the average by the total hours worked:

$C_{total}=\bar xt,\bar x=8.5,t=8\\\\C_{total}=8.5\times 8=68$

Given that each car uses 1/3 tin of wax, the total containers is calculated as:

$Containers=\bar x_c n,n=68,\bar x_c=\frac{1}{3}\\\\=\frac{1}{3}\times 68\\\\=22.67$

Hence, the car wash uses 22.67 containers of wax per day.
