Answer:

12 cm

Step-by-step explanation:

The question is not complete Let us assume the base has a length of 15 cm and width of 10 cm.

A pyramid with a rectangular base is a rectangular pyramid. Its base is rectangular and on each side of the base, it has a triangular face known as lateral face.

The volume of a rectangular pyramid is one third of the product of the length of the base, breadth of the base and height of the pyramid given by:

Volume = (length × breadth × height) / 3

Let us assume the base has a length of 15 cm and width of 10 cm.

Given that the volume = 600 cm³.

Volume = (length × breadth × height) / 3

600 = (15 × 10 × height)/3

1800 = 150 × height

height = 1800 / 150

height = 12 cm

What is the value of -6+3-3(-18) ? (Need ASAP with steps!)

oee [108]

-6+3-3(-18)

Okay.

Work from left to right.
-6 plus 3 equals -3.
(Think of it as in a number line, from the spot of -6, move right three units. This will give you -3. Anyways..)

Now you have -3-3
The result is -6.

-6(-18)
Negative six times negative eighteen equals positive 108.

The answer is 108.

Food and clothing are shipped to victims of a natural disaster. Each carton of food will feed 13 people, while each carton of c

lutik1710 [3]

Answer:

233 cartons of food; 467 cartons of clothing

Step-by-step explanation:

This linear programming problem can be formulated as two inequalities (in addition to the usual constraints that the variables be non-negative). One of these expresses the constraint on weight. Let f and c represent numbers of food and clothing containers, respectively.

40f +25c ≤ 21000

The other expresses the limit on volume.

20f + 5c ≤ 7000

_____

Feasible Region vertex

We can subtract the boundary line equation of the first inequality from that of 5 times the second to find f:

5(20f +5c) -(40f +25c) = 5(7000) -21000

60f = 14000

f = 233 1/3

The second boundary line equation can be rearranged to find c:

c = 1400 -4f = 466 2/3

The nearest integer numbers to these values are ...

(f, c) = (233, 467)

The other vertices of the feasible region are associated with one or the other variable being zero: (f, c) = (0, 840) or (350, 0).

Check of Integer Solution

Trying these in the constraint inequalities gives ...

40·233 +25·467 = 20,995 < 21000
20·233 +5·467 = 6995 < 7000

Selection of the Answer

The answer to the question will be the feasible region vertex that maximizes the number of people helped. That is, we want to maximize ...

p = 13f + 6c

The values of p at the vertices are ...

p = 13·233 + 6·467 = 5831

p = 13·0 + 6·840 = 5040

p = 13·350 + 6·0 = 2100

The most people are helped when the plane is filled with 233 food cartons and 467 clothing cartons.
