The bed of a truck is stacked with with boxes of paper. The boxes are stacked 5 boxes deep by 4 boxes high by 4 boxes across

marysya [2.9K]

Answer:

3

Step-by-step explanation:

The boxes are stacked 5 boxes deep by 4 boxes high by 4 boxes across, then there are $5\cdot 4\cdot 4=80$ boxes in total.

The mass of 1 box of paper is 22.5 kilograms, so 80 boxes weigh $22.5\cdot 80=1800$ kilograms.

When the driver is in the truck, the mass is 2948.35 kilograms, then the total mass is

$2948.35+1800=4748.35\ kg.$

Let n be the number of boxes of paper the driver must deliver at the first stop. Their weigth is 22.5n kg and the weight of the truck without n boxes is

$4748.35-22.5n\ kg.$

Trucks with a mass greater than 4700 kilograms are not allowed over the bridge, thus

$4748.35-22.5n48.35,\\ \\n>\dfrac{967}{450}=2\dfrac{67}{450}.$

Hence, the driver must deliver at least 3 boxes at the first shop.

A construction company in Naples, Florida, is struggling to sell condominiums. In order to attract buyers, the company has made

Jobisdone [24]

Answer:

i) 25.25%

ii) 2.28%

Step-by-step explanation:

In this case we can use a normal distribution calculator. Setting the mean as 210000 and the standard deviation as 15000, we find that the area below 200000 is 0.2525. So the probability that the condominium will sell at $200.000 is 25.25%.

The area above 240000 is 0.0228, so the probability that the condominium will sell at $240.000 is 2.28%

You manage an ice cream factory that makes two flavors: Creamy Vanilla and Continental Mocha. Into each quart of Creamy Vanilla

nadezda [96]

Answer:

You should make 150 quarts of Creamy Vanilla and 50 quarts of Continental Mocha.

Step-by-step explanation:

This problem can be solved by a system of equations.

The largest profit is going to earned when all the eggs and cups of cream in stock are used.

I am going to call x the number of quarts of Creamy Vanilla and y the number of quarts of Continental Mocha.

The problem states that each quart of Creamy Vanilla uses 2 eggs and each quart of Continental Mocha uses 1 egg. There are 350 eggs in stock, so:

$2x + y = 350$

Each quart of Creamy Vanilla uses 3 cups of cream, as does each quart of Continental Mocha. There are 600 cups of cream in stock.

So:

$3x + 3y = 600$ Simplifying by 3.

$x + y = 200$

We have the following system

$1)2x + y = 350$

$2)x + y = 200$

I am going to multiply 2) by (-1) and then add with 1), so i can eliminate y

$1)2x + y = 350$

$2)-x - y = -200$

$2x - x + y - y = 350 - 200$

$x = 150$

$x + y = 200$

$y = 200 - 150 = 50$

You should make 150 quarts of Creamy Vanilla and 50 quarts of Continental Mocha.
