Answers

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

A tepee is designed to have a diameter of 10 feet and the volume of 419 ft.³ at what height the support poles crossed with some of the tepee correctly?

Answers

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.

Find, to the nearest degree, the angle of elevation of the sun at a time when a tree 20 feet high casts a shadow 12 feet long .

Answers

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°

Find an angle α that is coterminal with an angle measuring −460∘, where 0∘≤α<360∘. Do not include the degree symbol in your answer. For example, if your answer is 20∘, you would enter 20.

Answers

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°

23F 58F 62F 64F 64F 65F
a. 35
b. 42
c. 7
d. 23

Answers

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.

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:

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

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.)

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.
