Answer:

The cost of extracting the first 50 tons of copper is $151,000.

Step-by-step explanation:

Start-up costs of $150,000.

For the 50 tons of cooper.

C(x) = 0.6 + 0.008x

So

C(50) = 0.6 + 0.008*50 = 1

1 thousand dollars.

So

$150,000 + $1,000 = $151,000

The cost of extracting the first 50 tons of copper is $151,000.

Write one inequality statement to show the relationship among the following shoe sizes: 10 1/2, 8, and 9.
astraxan [27]

Answer:

a) 8 < 9 < 10 1/2

b) 10 1/2 > 9 > 8

Step-by-step explanation:

We can use inequalities to order shoe sizes. We need to know what the symbols mean, for example < means "is lower than" while > means "is greater than". We know that 8 is lower than 9, and 9 is lower than 10 1/2 (which can be written also as 10.5), so we can write:

a) 8 < 9 < 10 1/2

The other way around would be to say that 10 1/2 is greater than 9, and 9 is greater than 8, which means:

b) 10 1/2 > 9 > 8

12ad^3 and which terms are like terms?<br> 15a^3d<br> 12d^3<br> 3ad^3<br> 10ad
storchak [24]
Like terms are terms with the exact same variables, and the exact same degree of each variable...simply put, the exponents of each variable have to be exactly the same.
The given term 12 ad³ has variables a and d. a has a degree of 1 and d has a degree of 3.
The term 3ad³ has the same variables and the same degree, and is therefore the like term.
