Last summer, Marrero was at Newgrange, a stone mound in Ireland that has a diameter of 250 feet. He found a walkway 62 feet long that leads to the center of the mound. Help Marrero find perpendicular distance x from the end of the walkway to either side of the mound.

Answers

Answer:

108 ft

Step-by-step explanation:

The line connecting the center with the end of the walkway is radius and is the hypotenuse of the right triangle.

Horizontal leg is the distance x.

Vertical leg has the length:

(250)/2 - 62 = 63 ft

Using Pythagorean theorem to find the length of x:

x² = (250/2)² - 63²x² = 125² - 63²x² = 11656x = √11656x = 107.96 ≈ 108

What are the limitations of using the Fundamental Counting Principle when determining the probability of an outcome??

Answers

n A) outcome in event which A and B out outcome in event of A and B which it’s n (A x n B probability of the outcomes in fundamental counting. Hope this helps with your question..

The limitations of using the Fundamental Counting Principle when determining the probability of an outcome is that it is not simple and it does not apply to non-uniform probability distribution

What is probability?

Probability is the likelihood or chance of an event happening or not.

Probability values helps in decision-making in day-to-day activities.

The Fundamental Counting Principle in probability is a way to determine the number of outcomes in a probability problem. It states that if there are p ways to do one thing and q ways to do another, the number of way to do both things is p × q.

However, this principle is limited for non-uniform probability distribution and for larger samples space.

Therefore, the limitations of using the Fundamental Counting Principle when determining the probability of an outcome is that it is not simple and it does not apply to non-uniform probability distribution.

An iPod uses a standard 1.7 volt battery. How much resistance is in the circuit if it uses a current of
0.03 amps?

Answers

Answer:

R = 56.6 ohms

Step-by-step explanation:

Given that,

The voltage of the battery, V = 1.7 volt

We need to find the resistance in the circuit if it uses a current of 0.03 A.

Let the resistance be R. It can be solved using Ohms law as follows :

V = IR

[tex]R=\dfrac{V}{I}\\\\R=\dfrac{1.7}{0.03}\\R=56.6\ \Omega[/tex]

So, the resistance in the circuit is 56.6 ohms.

Work for 19:

The chart is incorrect because it calculates 40% of 34 instead of 40 percent of x (we got 85% for our answer but I'm using x as the unknown number) results in the number of 34.

Percentage of 40% of what number = 34?

40% of what number = 34 is equivalent to: 40% × ? = 34

--------------------------

40% × ? = 34

? =

34 ÷ 40% =

34 ÷ (40 ÷ 100) =

(100 × 34) ÷ 40 =

3,400 ÷ 40 =

If 40% × 85 = 34 =>

Divide 34 by 85...

Answer:

29.25

or 29.3 if rounded to 10s place.

Step-by-step explanation:

Answer:

[tex]\Huge\boxed{29.3}[/tex]

Step-by-step explanation:

Hello There!

Remember The Trigonometric Ratios

Sin = opposite divided by hypotenuse

Cos = adjacent divided by hypotenuse

Tan = opposite divided by adjacent

We need to find the measure of angle X given the opposite side length and hypotenuse

Opposite and hypotenuse correspond with sine so we are going to use sine to solve for x

We create an equation: [tex]sin(x)=\frac{43}{88} \\[/tex]

[tex]\frac{43}{88} =.4886363636\\sin(x)=.4886363636[/tex]

Now we want to get rid of the sin

To do so we take the inverse of sin (which would be arcsin) and apply it to each side

[tex]arcsin^-^1(sinX)=x\\arcsin^-^1(.4886363636)=29.25099306[/tex]

finally we round to the nearest tenth

we're left with x = 29.3

Using midpoint formula we find the values of x and y

(- 3 + x)/2 = 5 ⇒ -3 + x = 10 ⇒ x = 10 + 3 ⇒ x = 13(6 + y)/2 = 8 ⇒ 6 + y = 16 ⇒ y = 16 - 6 ⇒ y = 10Q = (13, 10)

Answer:

x = 34

Step-by-step explanation:

according to the problem ::

(2x + 9)° + (3x + 1)° = 180° [ since, the opposite angles of a cyclic quadrilateral are supplementary ]

or, 2x + 9 + 3x + 1 = 180

or, 2x + 3x = 180 - 10

or, 5x = 170

or, x = 170 / 5

or, x = 34

therefore, the value of x is 34°

This pyramid, "the castle," is just one part of a large archaeological site that was a major city almost fifteen hundred years ago. It is believed that two groups of people, the Mayans and the Toltecs, called this city their home. The city included a marketplace, a plaza, a church, and an observatory, as well as a ball court, a temple for sacrifices, and a sinkhole which provided water for the people. The pyramid has four sides, each with ninety-one stairs; the four sets of stairs combine with the platform at the top to equal 365 three hundred sixty-five stairs-one for each day of the year. In addition, at sunrise and sunset on the spring and autumn equinoxes, the sun casts the shadow of a serpent moving down the pyramid toward the sinkhole. The observatory, used to study the sun, moon, and stars, provides further evidence of the Mayans' and Toltecs' interest in astronomy.
