Answer:

the truck will over load with 13 refrigerators and 8 pianos

Step-by-step explanation:

13 refrigerators is 2600 lbs

8 pianos is 4200 lbs

both added together is 6800 lbs

the truck can only hold 5900 so 13 refrigerators and 8 pianos is too heavy

Answer:

200r +525p ≤ 5900
see below for a graph
yes, the truck would be overloaded

Step-by-step explanation:

The weight of r refrigerators is 200r. The weight of p pianos is 525p. The total weight must not exceed 5900 lb. So, the total weight of r refrigerators and p pianos must satisfy ...

200r +525p ≤ 5900

In addition, we cannot have negative refrigerators or pianos, so we must also have ...

r ≥ 0

p ≥ 0

A graph is attached.

_____

The point (r, p) = (13, 8) is not in the solution space. 13 refrigerators and 8 pianos would overload the truck.

Calculate the perimeter of a square whose diagonal measures 29 dm.

mojhsa [17]

Answer:

$4\sqrt{420.5}$ dm

Step-by-step explanation:

A square's diagonal cuts across the square, making two right triangles where the diagonal is the hypotenuse.

We have a right triangle with a hypotenuse of 29, and two legs that are the same length (because they are sides of a square)

So, we can use pythagoreans theorem to find the lengths of the legs, or sides of the square.

$a^2 + a^2 = 29^2$

$2a^2 = 841$

$a^2 = 420.5\\$

$a = \sqrt{420.5}$

Now that we have a side length of $\sqrt{420.5}$ , we just have to multiply that by 4, since a square has 4 sides. This leaves us with a final perimeter of:
