F. x°
The measure of the missing angle is​

Answers

Answer:

F = 93

Step-by-step explanation:

The angles of a hexagon should add up to 720 degrees.

Simply subtract all of the numbers and you get 93 degrees.

Since there are six angles, the shape is hexagon.

The sum of all the angles in a hexagon is 720°.

x° + 145° + 163° + 60° + 135° + 124° = 720°

x° + 627° = 720°

x = 720° - 627°

x = 93°

The measure of the missing angle is 93°.

The perimeter of the triangular park shown on the right is 11x - 7. What is the missing length?

Answers

Answer:

Step-by-step explanation:

the perimeter is the distance around the shape, we get this by adding all the sides, call the missing side y and set up an equation for the perimeter

11x-7 = 4x+2 + x-5 + y

solve for y

11x-7 = 5x -3 + y

A sum of money amounts to 10000 after 5 years and 15000 after 8 years at the same rate of simple
mterest. Find the rate of interest per annum.​

Answers

Answer:

Rate of interest = 99.99%

Step-by-step explanation:

The computation of the rate of interest is shown below:

Given that

The amount after 5 years is 10,000

And, after 8 years it is 15,000

so for 3 years, it is

= 15000 - 10000

= 5000

Now the simple interest for one year

= 5000 ÷ 3

And, for five years, its is = 5000 ÷ 3 × 5

= 8333.33

Now the principal amount is

= 10,000 - 8333.33

= 1666.67

Now finally the rate of interest is

8333.33 = 1666.67 × Rate of interest × 5

Rate of interest = 99.99%

I had been fording streams more and more difficult to cross and wading bogs and swamps that seemed more and more extensive and more difficult to force one's way through. Entering one of these great tamarac and arbor-vitae swamps one morning, holding a general though very crooked course by compass, struggling through tangled drooping branches and over and under broad heaps of fallen trees, I began to fear that I would not be able to reach dry ground before dark, and therefore would have to pass the night in the swamp and began, faint and hungry, to plan a nest of branches on one of the largest trees or windfalls like a monkey's nest, or eagle's, or Indian's in the flooded forests of the Orinoco described by Humboldt.[3] But when the sun was getting low and everything seemed most bewildering and discouraging, I found beautiful Calypso on the mossy bank of a stream, growing not in the ground but on a bed of yellow mosses in which its small white bulb had found a soft nest and from which its one leaf and one flower sprung. The flower was white and made the impression of the utmost simple purity like a snowflower. No other bloom was near it, for the bog a short distance below the surface was still frozen, and the water was ice cold. It seemed the most spiritual of all the flower people I had ever met. I sat down beside it and fairly cried for joy.[4] It seems wonderful that so frail and lovely a plant has such power over human hearts. This Calypso meeting happened some forty-five years ago, and it was more memorable and impressive than any of my meetings with human beings excepting, perhaps, Emerson and one or two others. When I was leaving the University, Professor J.D. Butler said, "John, I would like to know what becomes of you, and I wish you would write me, say once a year, so I may keep you in sight." I wrote to the Professor, telling him about this meeting with Calypso, and he sent the letter to an Eastern newspaper [The Boston Recorder] with some comments of his own. These, as far as I know, were the first of my words that appeared in print.[5] How long I sat beside Calypso I don't know. Hunger and weariness vanished, and only after the sun was low in the west I splashed on through the swamp, strong and exhilarated as if never more to feel any mortal care. At length I saw maple woods on a hill and found a log house. I was gladly received. "Where ha ye come fra? The swamp, that awfu' swamp. What were ye doin' there?" etc. "Mony a puir body has been lost in that muckle, cauld, dreary bog and never been found." When I told her I had entered it in search of plants and had been in it all day, she wondered how plants could draw me to these awful places, and said, "It's god's mercy ye ever got out."[6] Oftentimes I had to sleep without blankets, and sometimes without supper, but usually I had no great difficulty in finding a loaf of bread here and there at the houses of the farmer settlers in the widely scattered clearings. With one of these large backwoods loaves I was able to wander many a long wild fertile mile in the forests and bogs, free as the winds, gathering plants, and glorying in The words that Muir uses in his essay reveal that he relates to nature as a(n) emotional professor objective notetaker passionate observer removed reporter
