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 1

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

Each wheel on the train has a diameter of 1.8 m.
Work out the number of complete turns each wheel makes in travelling the 6.5 km..

Answers

Answer: 1150 turns

Step-by-step explanation: radius of wheel is 0,9 m

In one turn wheel moves 2·pi·0,9 m = 5,652 m

You divide 6500 m : 6,652 m = 1150

The number of complete turns each wheel makes in travelling the 6.5 km is 1150 turns

What is a circle?

A circle is a shape consisting of all points in a plane that are given the same distance from a given point called the center.

We know that circumference of the circle that has a radius of r is defined as the product of diameter to the pie value.

The circumference of the circle = 2πr

WE have been given the radius of wheel is 0.9 m

In one turn wheel moves 2πr

= 2 x π x 0.9 m

= 5.652 m

Now we have to divide 6500 m : 6.652 m

= 1150

Neptune's average distance from the Sun is 4.503 × 109 km. Mercury's average distance from the Sun is 5.791 × 107 km. About how many times farther from the Sun is Neptune than Mercury

Answers

9514 1404 393

Answer:

Step-by-step explanation:

The ratio of distances is ...

Neptune distance / Mercury distance = (4.503×10^9)/(5.791×10^7)

= 450.3/5.791 = 77.76 . . . . cancelling factors of 10^7

Neptune is about 77.76 times as far from the Sun as Mercury is.

In the given diagram , TY is a tangent to the circle TVS . If <SVT = 48° and |VS| = |ST| . What is < VTY.

Answers

Answer:

84°

Step-by-step explanation:

∠VTY is the tangent chord angle

Tangent chord angle is the half of the intercepted arc

∠TSV is the inscribed angle.

Inscribed angle is the half of the intercepted arc

Since both of the mentioned angles refer to same arc, they are of same value.

∠VTY = ∠TSV

ΔTVS is isosceles as VS = ST, therefore the opposite angles are same.

m∠T = m∠V = 48°

The measure of angle S

m∠S = 180° - 2*48° = 84°

The required angle

m∠VTY = 84°

Answer:

∠VTY = 84°

Step-by-step explanation:

because ΔTSV is isosceles (ST = SV) then ∠VTS = ∠SVT = 48°

Then ∠VST = 84° (180 - 48 - 48 = 84)

Well, I'm going back to the picture is worth a thousand words again.

Sketch attached:

A line from S to the center bisects ∠VST into two 42° angles.

A line from T to the center forms a 42° angle with line ST.

48°-42° = 6° = angle from perpendicular line CTR to line VT.

90° - 6° = 84° for ∠VTY

HELP One angle of a regular hexagon measures (2x+10)°Find x

Step-by-step explanation:

total number of degrees in a 6-sided figure is (6-2)x180, which is 720°

720/6 = 120

Each angle of a hexagon measures 120°

2x+10 = 720

A handbag company had 5% of the market in 2011 in 2015 it had 23%.

(a) Write a linear equation expressing the percentage of the luxury handbag market y that the company had x years after 2000

Answers

Answer:

[tex]y = 0.045x -0.445[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1)=(11,5\%)[/tex] ---- in 2011

[tex](x_2,y_2)=(15,23\%)[/tex] --- in 2015

Required

Linear equation for x years after 2000

First, calculate the slope

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{23\% - 5\%}{15 - 11}[/tex]

[tex]m = \frac{18\%}{4}[/tex]

[tex]m = 4.5\%[/tex]

[tex]m = 0.045[/tex]

The equation for x years after 2000 is:

[tex]y = m(x - x_1) + y_1[/tex]

[tex]y = 0.045(x - 11) + 5\%[/tex]

[tex]y = 0.045x - 0.495 + 0.05[/tex]

Brenda likes to swim when she is at her cottage. She swam 12 m north from her dock, and then 60 m east. How far will she have to swim if she wants to go directly back to the dock?

72 m

If Brenda is going 12m north and 60m east, that's a total of 72m because 12+60 = 72, so if Brenda wants to come directly back to the dock she will just have to follow her footsteps back 72m.

-1/3x

What term can you add to 5/6x -4 to make it equivalent to 1/2x - 4?

First I see the constants (-4) are equal to each other, so I don’t need to add anything to them.

5/6x and 1/2x are different though, so I know I need to add something, let’s call it y, to 5/6x to make it equal 1/2x

To add fractions, they have to have the same denominator. 1/2x becomes 3/6x.

5/6x + y = 3/6x
Subtract 5/6x from both sides
y = -2/6x

-2/6x can be simplified to -1/3x, so -1/3x is the answer.
