Answer:

6000 m^3

Step-by-step explanation:

The basic formula for the area of a pyramid is 1/3 * b * h

where b is the base and h is the height.

The base is a square, so, we can find the area by squaring the side:

30^2 = 900.

Now, we can plug the values we have into the formula from above:

1/3 * 900 * 20

6000 m^3

Answer:

I don't have the options but I know parallel lines will never touch, they have the same slope, and the distance between the lines never changes

Answer:

The coterminal angle is 260°

Step-by-step explanation:

Suppose that we have an angle A.

All the coterminal angles to A are written as:

B = A + n*360°

Where n is any whole number.

Notice that if n = 0, we get:

B = A + 0*360° = A

So A is coterminal with itself, which is trivial.

Now we want to find a conterminal angle to -460° such that it is in the range:

0° < α < 360°

So we just need to find a value of n such that:

α = -460° + n*360°

is on the given range.

We can assume that n = 2 will work, let's check:

α = -460° + 2*360° = 260°

α = 260°

And this angle is in the given range:

0° < 260° < 360°

Answer:

B.11+7=18

Step-by-step explanation:

its B because since its 7 days AFTER it means your going to have to add the 11 days plus this 7 days. Which would give you 18 days left till Susie's concert.

Answer:

Angle of elevation of sun = 59°

Step-by-step explanation:

Given:

Height of tree = 20 feet

Shadow of tree on ground = 12 feet

Find:

Angle of elevation of sun

Computation:

Height of tree = Perpendicular

Shadow of tree on ground = Base

Using trigonometry function;

Tanθ = Perpendicular / Base

Tanθ = 20 / 12

Tanθ = 1.66

Tanθ = Tan 59°

θ = 59°

So,

Angle of elevation of sun = 59°

Answer:

It will take Amanda 3 track practices to run 29 miles.

Step-by-step explanation:

29-14=15

15/3=5

or

14+5x=29

subtract 14 from both sides

5x=15

divide both sides by 3

x=3

Answer: 5

Step-by-step explanation:

You see 2x2 = 4 right and since this is operation 2 / 10 = 5  and 6-5 = 1 so add 1 and that gives you 5

2x2 = 4 /  10/2 = 5 /  6-5 = 1 +4 = 5

Answer:

= 4x + -4

Step-by-step explanation:

Let's simplify:

[tex]2x(2) + 6 -10 \\ = 4x + 6 - 10[/tex]

Combine Like Terms:

[tex]=4x+6+−10

\\ =(4x)+(6+−10) \\ =4x+−4[/tex]

Answer:

Perimeter = 2 ( l + w )

if u r given for rectangle thats the formula

Step-by-step explanation:

To find the perimeter of a rectangle, add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width).

Answer:

1/45

Step-by-step explanation:

Here is the complete question

here are 2 yellow, 3 green, 1 orange, and 4 red cards in a stack of cards turned facedown. Once a card is selected, it is not replaced. Find each probability.

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.

1. P(two yellow cards)

there are a total of 10 cards and 2 yellows cards. If 1 yellow card is picked, it would remain 1 yellow card and 9 cards

P(two yellow cards) = 2/10 x 1/9 = 1/45

Step-by-step explanation:

Given:

The temperature of the first 6 days in march is:

23F, 58F, 62F, 64F, 64F, 65F

23 F is removed from the data set.

To find:

How much greater is the range of the original 6 temperatures than the range of the 5 temperatures.

Solution:

Range of a data set is:

Range = Maximum value - Minimum value

The given data set is:

23 F, 58 F, 62 F, 64 F, 64 F, 65 F

The range of given data set is:

Range = 65 - 23

           = 42

If the temperature 23 F is removed from the data set, then the new data set is:

58 F, 62 F, 64 F, 64 F, 65 F

The range of this new data set is:

Range = 65 - 58

           = 7

Now, the difference between original range and new range is:

[tex]42-7=35[/tex]

The original range is 35 more than the new range. Therefore, the correct option is a.

Answer:

The required height is equal to 5.33 feet.

Step-by-step explanation:

Given that,

Diameter, d = 10 feet

Volume, V = 419 ft.³

We need to find the height the support poles crossed with some of the tepee correctly. Let the height is h.

The tepee is in the form of a  cylinder. The volume of a cylinder is given by :

[tex]V=\pi r^2 h\\\\h=\dfrac{V}{\pi r^2}\\\\h=\dfrac{419}{3.14\times 5^2}\\\\h=5.33\ ft[/tex]

So, the required height is equal to 5.33 feet.

Answer:

Area required for circular hot tube = 6,218 inch² (Approx.)

Step-by-step explanation:

Given:

Diameter of circular hot tube = 89 inches

Value of π = 3.14

Find:

Area required for circular hot tube

Computation:

Radius of hot tube = Diameter / 2

Radius of hot tube = 89 / 2 inches

Area required for circular hot tube = Area of circle

Area of circle = πr²

Area required for circular hot tube = πr²

Area required for circular hot tube = (3.14)(89/2)²

Area required for circular hot tube = (3.14)(7921 / 4)

Area required for circular hot tube = (3.14)(1,980.25)

Area required for circular hot tube = 6,217.985

Area required for circular hot tube = 6,218 inch² (Approx.)

Answer:

Step-by-step explanation:

CD = 90 - 53 = 37°

AB = 180 - 79 - 53 = 48°

ED = 180 - 37 = 143°

EB = 180 - 53= 127°

BDE = 53 + 37 + 143 = 233°

DEC = 360 - 37 = 323°°
