Answer:

20 people

Step-by-step explanation:

The volume of a cuboid is equal to length * breadth * height.

First, we want to figure out the values relative to each other. Everything is in centimeters except the breadth, which is 0.07m. To convert meters to centimeters, we can multiply by 100: 0.07 * 100 = 7, so the breadth is 7cm.

Next, the volume is  length * breadth * height = 5cm * 7cm * 8cm = 280cm³. Each person occupies 14cm³. To find how many people can occupy the cube, we can divide the volume by the space each person takes, so

280cm³/14cm³ = 20 people

Note that we can divide because each person takes x amount of space, and the total space, z, can be represented by x * y = z, with y representing the amount of people, because we add x space for each person. Dividing both sides by x, we get y = z/x

Write a polynomial in standard form that represents the area of the shaded region.
Paladinen [302]

Answer:

Area of the smaller square is x * x, which is x^2

Area of the larger square is (x + 7)(x + 7), which is x^2 + 14x + 49

The area of the shaded area = Area of the larger square - Area of the smaller square

Area of the shaded region = x^2 + 14x + 49 - x^2

Area of the shaded region is 14x + 49.

Why is volume of a cone is written in cubic units
frutty [35]

Answer:

The formula for the volume of a cone is 1/3 Bh. This means 1/3 the Area of the base times the height. You can calculate the area by multiply length and width. Area is two-dimensional. Multiplying height by it adds another dimension. When writing area, we say units squared. When writing volume, we say units cubed, because it is three dimensional.

The Varners live on a corner lot. Often children cut across their lot to scar walking distance. The diagram to the right represe
icang [17]
About 12.56 units. 
Solve for x by plugging in values into Pythagorean theorem.
a^{2} +b^{2} = c^{2}
x^{2} +(x+12)^{2} = 34^{2}
Simplify
2x^{2} + 24x+144 = 1156
Subtract 144 from both sides
2x^{2} + 24x = 1012
divide both sides by 2
x^{2} + 12x = 506
complete the square
x^{2} + 12x + 36 = 506 +36 . = (x+6)^2 = 542
take the square root of both sides.
x+6 = 23.28
subtract by 6 to get  about 17.28 for x.
Plug in values for x to get distance traveled on outside of the yard.
17.28 + (17.28 +12) = 46.56
subtract 34 from the length to get the difference in travel. 46.56-34=12.56

The actual length of side t is 0.045 cm. Use the scale drawing to find the actual side length of w. A) 0.06 cm B) 0.075 cm C) 0.
Tems11 [23]

Answer: The answer is B 0.075 cm


Step-by-step explanation:

Since the drawings is a scale of the original you must use a proportion to solve the desired side. 0.045/.9=w/1.5;w=0.075.
