13 cans of paint with 5/6 liters of paint in each were used to paint 4 identical cars. How can you calculate the amount of paint

brilliants [131]

Answer:

(B) 5/6 ·13÷4

(C) 5/6 ÷4·13

(D) 5/6 · 13/4

Step-by-step explanation:

Amount of paint per can = $\frac{5}{6}$ liters.

Number of cans used to paint 4 cars = 13

Total amount of paint used for 4 cars = $13 * \frac{5}{6}$ liters.

= $\frac{13 * 5}{6}$ liters.

= $\frac{65}{6}$ liters.

Total amount of paint used for 1 car = $\frac{65}{6} \div 4$ liters.

= $\frac{65}{24}$ liters.

Of the given options, option B,C and D correspond to the same value.

Answer:

A. $(x^{2}-7)\cdot (x-11)$

Step-by-step explanation:

The third order polynomial is factored herein:

$x^{2}\cdot (x-11) - 7\cdot (x-11)$

$(x^{2}-7)\cdot (x-11)$

Which represents answer A.

Number 3 please! pic is above^

zmey [24]

Answer:

Step-by-step explanation:

Slope = (y2 -y1)/(x2-x1)

y2 = 800, y1 = 400, x2= 4, x1= 2

Slope = (800-400)/(4-2)

= 400/2

= 200calories/hr

Jack's Lumber Yard receives 8,000 large trees each period that it subsequently processes into rough logs by stripping off the tr

nasty-shy [4]

Answer:

1. $3,960,000

2. $3,840,000

3. Sell the logs.

Step-by-step explanation:

The questions are incomplete:

1. What is the contribution to income from selling the logs for log cabin construction?

2. What is the contribution to income from processing the logs into lumber?

3. Should Jack’s continue to sell the logs or process them further into lumber?

1. The contribution income is the total income generated by the sales of the rough logs. Each one contributes with $495.

Contribution to income (log cabin construction) = $495*8,000 = $3,960,000

2. In this case, we have to calculate what is the profit after processing each board, then multypling by the amount of boards per log and lastly multiplying by the total amoun of logs.

Contribution to income (processed board) = $(0.75-0.15)*800*8000

Contribution to income (processed board) = $0.6*800*8000

Contribution to income (processed board) = $480*8000 = $3,840,000

3. Jack should continue to sell logs for cabin construction because the profit per log is higher than for the processed board ($495/log versus $480/log).
