Swim flippers are helpful for scuba

$15 per day, plus 8% tax. How
much will it cost, including tax, to
rent them for three days?

Answers

Answer:

The answer would be $48.60.

Step-by-step explanation:

Some people could probably answer it better but here's my way: When you have a percentage of something you bring it to the decimal. 8% would be 0.08. We take this and multiply it by the cost: 0.08 times 15, giving us $1.2 per $15 dollars spent. 1.2 times the 3 days would be 3.6 and 15 times 3 is 45 together this would give you the grand total of $48.60.

69.08 cm

Explanation :

Given :

Radius of a circle = 11 cm

To Find :

Circumference of the circle = ?

Solution :

As, we have radius of the circle is 11 cm and to find circumferemce, we have a formula :

[tex] \large \underline{\boxed{\bf{Circumference = 2\pi r}}}[/tex]

By filling value of r = 11 cm and π = 3.14, we have :

[tex] \sf : \implies Circumference = 2 \times 3.14 \times 11 \: cm[/tex]

[tex] \sf : \implies Circumference = 2 \times \dfrac{314}{100} \times 11 \: cm[/tex]

[tex] \sf : \implies Circumference = \dfrac{628}{100} \times 11 \: cm[/tex]

[tex] \sf : \implies Circumference = \dfrac{6908}{100} \: cm[/tex]

[tex] \sf : \implies Circumference = 69.08\: cm[/tex]

Hence, circumference of the circle is 69.08 cm.

To find:

The scale factor.

Solution:

From the given graph it is clear that

ND = 3 units

N'D' = 6 units.

We know that,

[tex]\text{Scale factor}=\dfrac{\text{Side of image}}{\text{Corresponding side of original figure}}[/tex]

[tex]\text{Scale factor}=\dfrac{N'D'}{ND}[/tex]

[tex]\text{Scale factor}=\dfrac{6}{3}[/tex]

[tex]\text{Scale factor}=2[/tex]

Therefore, the scale factor is 2 and the correct option is A.

5 positive integers are arranged in ascending order, as follows:
7, 8, 11, 11, X
The median and the range are equal.
Find 2.

Answers

Answer:

X = 18.

Step-by-step explanation:

The median = 11 so the mean is also 11 (given).

So mean  = 11 = (7 + 8 + 11 + 11 + X) / 5

(37 + x)/ 5 = 11

x + 37 = 55

x = 55 - 37 = 18.

Answer: 4x + 2y

Step-by-step explanation: 1/2(6x-8y) = 3x - 4y

1/2 * 6x= 3x

1/2 * 8y = 4y

-3(x - 2y) = -3x + 6y

-3 * -2 = 6y

4x - 3x + 6y + 3x - 4y

= 4x + 2y

Find the solution to this system of equations and write it as an ordered
pair (x, y) *
3x + 3y = -18
2x - 4y= -6

Answers

Answer:

Step-by-step explanation:

Simplifying

3x + 3y = -18

Solving

3x + 3y = -18

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3y' to each side of the equation.

3x + 3y + -3y = -18 + -3y

Combine like terms: 3y + -3y = 0

3x + 0 = -18 + -3y

3x = -18 + -3y

Divide each side by '3'.

x = -6 + -1y

Simplifying

x = -6 + -1y

//////////////

Simplifying

2x + -4y = -6

Solving

2x + -4y = -6

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4y' to each side of the equation.

2x + -4y + 4y = -6 + 4y

Combine like terms: -4y + 4y = 0

2x + 0 = -6 + 4y

2x = -6 + 4y

Divide each side by '2'.

x = -3 + 2y

Simplifying

x = -3 + 2y

The master roofer wants to put the ladder on the side of the house but she doesn't
know if it can be set at the proper angle. What will be the angle of elevation if the
10-foot long ladder is placed 1 feet from the wall?

Answers

Answer: About 84.261 degrees

Step-by-step explanation:

To find the angle of elevation, we can create a triangle and solve for the angle.

First, we can imagine a triangle with side A being the ground between the base of the ladder and the wall, side B being the wall (from the base of the wall to where it touches the top of the ladder), and side C being the ladder (from where it touches the ground to where it touches the wall).

In the problem, it has already given us two of the side lengths we need to solve for the angle of elevation:

1. We know that the ladder is 10 feet tall, so we can say that side C is 10.

2. We know that the ladder base is placed 1 foot from the wall, so we can say that side A is 1.

The angle of elevation is the angle that the ladder is tilted from the ground, or the angle between the ground (side A) and the ladder (side C). These sides relative to the angle would be the adjacent (side A) and the hypotenuse (side C).

To calculate for the angle, we can use the cosine function. (cos = adjacent / hypotenuse)

To find the angle of elevation (which we can call angle b), we can use:

cos(b) = A / C

arccos(A / C) = b

(Note: arccos is the inverse of the cos function)

Then, we can plug in the values and get:

b = arccos(1 / 10)

b = 1.471 radians OR 84.261 degrees

Write a short paragraph explaining how the text supports the idea that Fawcett was a remarkable man. Use at least two details from the text in your response.THE STORY 1 Since the dawn of the modern age, the notion of a pre-historic world, hidden deep in the jungle and untouched by the passage of time, has captivated our imaginations.2 Before Jurassic Park, before King Kong, there was The Lost World. Written in 1912 by Sherlock Holmes creator, Sir Arthur Conan Doyle, The Lost World was in turn largely inspired by the real-life adventures of one remarkable man: Col. Percy Harrison Fawcett.3 David Grann, a staff writer for The New Yorker magazine, says in his time Fawcett was a larger-than-life figure: Oh, he really was. I mean, he was the last of these kind of great territorial explorers who would plunge into the blank spots on the map, carrying a machete, essentially, and an almost divine sense of purpose.4 Grann was researching an article on Conan Doyle when he came across a reference to Fawcett.5 I had typed Fawcetts name into one of these newspaper databases, and up came all these kind of crazy headlines: Fawcett disappears into the unknown. A movie star kidnapped trying to save Fawcett.6 I had never heard of this man, and I quickly discovered there was this legendary figure, Grann said. And this enormous mystery that had been eclipsed by history. And it really intrigued me.7 So Grann started digging. Fawcett, he learned, was an honored member of Britains renowned Royal Geographical Society.8 He would live in the jungle for years at a time without contact with the world, Grann said. He discovered stories about how hed battle anacondas and electric eels, and how hed emerge with maps of regions that no one had ever came back from.9 In April 1925, Fawcett set out with just two othershis 21-year-old son Jack, and Jacks best friend, Raleigh Rimmelon what was to be his crowning adventure . . . finding the remains of a lost world he believed existed deep in the Amazon jungle of South America. 10 Fawcett called his mythical city, simply, Z. 11 After 30 years as an explorer, Fawcetts survival skills were unrivaled. But this time, he went in . . . and never came out. 12 Well, we know he got as far as a place called Dead Horse Camp, where he would send these dispatches back for five months, said Grann. And then after the fifth month, the dispatches ceased. And they were never heard from again. 13 . . . setting off one of the greatest manhunts of the 20th century. 14 George Dyott was the first, taking a film crew with him into the Amazon in 1928 and radioing back regular progress reports. 15 But he never found Fawcett. 16 In 1996 Brazilian financier James Lynch launched a multi-million dollar expedition to finally solve the mystery. But he and his party were kidnapped by tribesmen. 17 They were released only after surrendering $30,000 worth of gear. 18 Now, finally, after 85 years, the mystery that has tantalized so many may finally have been solved by perhaps Fawcetts least likely pursuer. 19 Grann turned his jungle adventure into a best-seller, The Lost City of Z, in which he recounts Fawcetts final days. 20 We stayed with many of the same tribes that Fawcett stayed with, said Grann. And to my astonishment, they had an oral history about Fawcett and his expedition. 21 It describes how Fawcett had insisted on moving eastward, towards the River of Death. And the tribe tried to persuade them not to go in that direction. In that direction were what they referred to as the fierce Indians. And off he marched. 22 And they could see the fire for five days, rising above the treetops. And then on the fifth day, it went out as if it was snuffed out. And they had no doubt that they had been killed by the Indians. 23 No physical trace of Fawcett has ever been found. But Granns efforts did bring one revelation to light: Fawcett may have been right about the lost civilization after all. 24 In the last few years, archaeologists are now going into this region using high-tech gadgetry that Fawcett could never imaginesatellite imagery, ground penetrating radars to pinpoint various artifacts, said Grann. And they are discovering ancient ruins scattered throughout the Amazon. 25 One archaeologist has found, in the very area where Fawcett believed he would find Z, 20 pre-Columbian settlements that had roads built at right angles, bridges, causeways, and that a cluster of these settlements that were interconnected had populations of between 2,500 to 5,000 people, which would have made them the size of many medieval European cities at the time.
