A candle maker has 4 1/2 pounds of clear wax. He wants to cut the wax into pieces that are 2/3 pound each. How many 2/3 pound pi

prisoha [69]

Answer:

a) 10 pieces of 2/3 pound can be made.

b) 0.54 pounds of wax is left over.

Step-by-step explanation:

Total amount of clear wax available = $4\frac{1}{2} = \frac{9}{2}$ pounds

So, the maker has in total 4.5 pounds of wax

Now, The weight of each piece = $\frac{2}{3} = 0.66$ pounds

To find the number of pieces that can be made out of 4.5 pounds of wax,

let that number = n

So, $n = \frac{\textrm{Total weight of the clear wax}}{\textrm{Weight of each wax}}$

or, n = $n = \frac{4.5}{0.66} = 6.81$

So, nearly 6 pieces can be made completely out of the clear wax

Left over amount of wax = Total weight - Weights of the pieces made

= 4.5- 6(0.66)

= 0.54 pounds

Hence, 0.54 pounds of wax is left over

krek1111 [17]

Answer:

The answer is option 1.

Step-by-step explanation:

You have to apply Gradient formula :

$m = \frac{y2 - y1}{x2 - x1}$

$let \: (x1 \: , \: y1) \: be \: ( - 2 \: , \: 0)$

$let \: (x2 \: , \: y2) \: be \: (0 \: , \: 4)$

$m = \frac{4 - 0}{0 - ( - 2)}$

$m = \frac{4}{2}$

$m = 2$
