A factory manager is packing engine components into wooden crates to be shipped on a small truck. The truck is designed to hold
Lemur [1.5K]

Answer: 63lbs

Step-by-step explanation:

The truck can only hold 16crates and each crate weigh 12lbs, the total weight of the 16 crates will be 12×16= 192lbs

This shows that the truck can only contain extra load of 1200lbs - 192lbs = 1008lbs (excluding weight of crates).

To get the shipment weigh close to the total of 1200lbs, the truck must be loaded with engine components not more than 1008lbs.

Since we have 16 crates to fill with engine components not more than 1008lb, each crates will therefore must not exceed 1008/16 pounds of engine components which is equivalent to 63lbs.

Therefore, the manager should instruct the workers to put 63lbs of machine components in "each crate" in order to get the shipment weight as close as possible to 1200 lbs.

The formula for the area of a triangle is . What is the length of the base, b, of a triangle with an area, A, of 110 m2 and a he
vodka [1.7K]

Answer:

b = 22 m

Step-by-step explanation:

The formula for calculating the area (A) of a triangle is

A = \frac{1}{2} bh

multiply both sides by 2 to eliminate the fraction

2A = bh ( divide both sides by h )

b = \frac{2A}{h}, hence

b = \frac{2(110)}{10} = \frac{220}{10} = 22 m

The product of two integers is 72. One number is two less than five times the other. Which of the following equations could be u
melisa1 [442]
Let the 2 integers be x and y.

Their product is 72, so we write: xy=72. (I)

One of them, say y, is 2 less than 5 times the other. We can write this as the equation:
                               y=5x-2. (II)

To find one of numbers, say x, we can substitute y with 5x-2, in the first equation:

xy=72,

x(5x-2)=72,

expanding the left hand side expression we get:

5x^2-2x=72.
