Estimate the square root of the following imperfect square:
7.
a. 2.2
b. 2.4
C. 2.6
d. 2.8

Answers

This problem is just try and error.

First we try number 2.5 since its the average of all the answers.

2.5^2=6.25

This is smaller than 7 so the answer is either 2.6 or 2.8

Now let's try 2.7

2.7^2=7.29

Which is bigger than 7 and that means the correct answer is 2.6 :)

c is the correct answer thanks

Verify that the segment lengths form a triangle. Is the triangle acute, right, or obtuse?

Answers

Answer:

The lengths do form a triangle and it is a right triangle.

Step-by-step explanation:

Part I:

To find out if 3 segment lengths form a triangle, you must verify that the sum of the two SMALLER sides (6+8) is GREATER than the longest side (10). That is true for this case. We have a triangle

Part II:

To find out the type of triangle, we must incorporate the Pythagorean theorem:

If [tex]c^2 = a^2 + b^2\\[/tex] then it is a right triangle. Substitute the values. (c=10, b=8, 6=a)[tex]10^2 = 6^2 + 8^2\\100 = 100[/tex]

Solve the equation x – 5 = 0.1(x + 5) for x

Answers

Answer:

Step-by-step explanation:

x - 5 = 0.1(x +5)

x - 5 = 0.1x + 5*0.1

x -5 = 0.1x + 0.5 {Add 5 to both sides}

x = 0.1x + 0.5 + 5

x = 0.1x + 5.5

x -0.1x = 5.5 {subtract 0.1x from both sides}

0.9x =5.5 {Divide both sides by 0.9}

x = 5.5/0.9

x = 55/9

x = 6 1/9

Answer:

x = ⁵⁵/₉ = 6¹/₉

Step-by-step explanation:

x - 5 = 0.1(x + 5) {multiply both sides by 10}

10x - 50 = x + 5 {subtract x from both sides}

9x - 50 = 5 {add 50 to both sides}

9x = 55 {divide both sides by 9}

x = ⁵⁵/₉ = 6¹/₉

Answers

Answer:

The way I was taught to do it is to change value into a total fraction, then multiple the numerators together, multiply the denominators together, and finally reduce as far as possible.

7/9 x 5 2/5 = 7/9 x 27/5 = 189/45 = 4 9/45 = 4 1/5

A hemispherical tank is filled with water and has a diameter of 15 feet. If water weighs 62.4 pounds per cubic foot, what is the total weight of the water in a full tank, to the nearest pound?

Answers

Answer:

55135 lbs (rounded to the nearest pound)

Step-by-step explanation:

diameter of tank = 15 ft

Radius = 15/2 =7.5

volume of hemisphere = 2/3 ×π× 7.5³=883.5729

total weight of water = 62.4 × 883.57 = 55134.768

55134.768 rounded to the nearest pound is 55135 lb

Enter an expression equivalent to (3x^2+2y^2-3x)+(2x^2+y^2-2x)-(x^2+3y^2+x) using the fewest number of possible terms

Answers

Answer:

2x(2x - 3)

Step-by-step explanation:

Given:

(3x^2+2y^2-3x)+(2x^2+y^2-2x)-(x^2+3y^2+x)

Written as:

(3x² + 2y² - 3x) + (2x² + y² - 2x) - (x² + 3y² + x)

= 3x² + 2y² - 3x + 2x² + y² - 2x - x² - 3y² - x

Collect like terms

= 3x² + 2x² - x² + 2y² + y²- 3y² - 3x - 2x - x

= 4x² + 0 - 6x

= 4x² - 6x

= 2x(2x - 3)

What is the difference between a third-person limited narrator and a third-person omniscient narrator? Now, imagine that you are helping a library move. You are lifting boxes of books onto a cart. Most of the boxes are full of many books, but one of the boxes was closed, only having a few books in it. You go to lift this box, not knowing it has less mass, with the same amount of force as you used to lift the full boxes. How will the acceleration of this box compare to the acceleration of a full box? Newtons second law of motion tells us that if the force remains constant and the mass is decreased, the object will accelerate at a faster rate. Because the acceleration increases when the mass decreases, we say that acceleration is inversely proportional to mass.Give an example of a situation where you might use the mathematical formula for Newton's second law to solve a problem. Explain how the formula would be useful in this situation. from Where I Lived, and What I Lived For in Waldenby Henry David ThoreauLook at a meeting-house, or a court-house, or a jail, or a shop, or a dwelling-house, and say what that thing really is before a true gaze, and they would all go to pieces in your account of them. Men esteem truth remote, in the outskirts of the system, behind the farthest star, before Adam and after the last man. In eternity there is indeed something true and sublime. But all these times and places and occasions are now and here. God himself culminates in the present moment, and will never be more divine in the lapse of all the ages. And we are enabled to apprehend at all what is sublime and noble only by the perpetual instilling and drenching of the reality that surrounds us. The universe constantly and obediently answers to our conceptions; whether we travel fast or slow, the track is laid for us. Let us spend our lives in conceiving then. The poet or the artist never yet had so fair and noble a design but some of his posterity at least could accomplish it.Let us spend one day as deliberately as Nature, and not be thrown off the track by every nutshell and mosquitos wing that falls on the rails. Let us rise early and fast, or break fast, gently and without perturbation; let company come and let company go, let the bells ring and the children crydetermined to make a day of it. Why should we knock under and go with the stream? Let us not be upset and overwhelmed in that terrible rapid and whirlpool called a dinner, situated in the meridian shallows. Weather this danger and you are safe, for the rest of the way is down hill. With unrelaxed nerves, with morning vigor, sail by it, looking another way, tied to the mast like Ulysses. If the engine whistles, let it whistle till it is hoarse for its pains. If the bell rings, why should we run? We will consider what kind of music they are like. Let us settle ourselves, and work and wedge our feet downward through the mud and slush of opinion, and prejudice, and tradition, and delusion, and appearance, that alluvion which covers the globe, through Paris and London, through New York and Boston and Concord, through Church and State, through poetry and philosophy and religion, till we come to a hard bottom and rocks in place, which we can call reality, and say, This is, and no mistake; and then begin, having a point d'appui, below freshet and frost and fire, a place where you might found a wall or a state, or set a lamp-post safely, or perhaps a gauge, not a Nilometer, but a Realometer, that future ages might know how deep a freshet of shams and appearances had gathered from time to time. If you stand right fronting and face to face to a fact, you will see the sun glimmer on both its surfaces, as if it were a cimeter, and feel its sweet edge dividing you through the heart and marrow, and so you will happily conclude your mortal career. Be it life or death, we crave only reality. If we are really dying, let us hear the rattle in our throats and feel cold in the extremities; if we are alive, let us go about our business.Time is but the stream I go a-fishing in. I drink at it; but while I drink I see the sandy bottom and detect how shallow it is. Its thin current slides away, but eternity remains. I would drink deeper; fish in the sky, whose bottom is pebbly with stars. I cannot count one. I know not the first letter of the alphabet. I have always been regretting that I was not as wise as the day I was born. The intellect is a cleaver; it discerns and rifts its way into the secret of things. I do not wish to be any more busy with my hands than is necessary. My head is hands and feet. I feel all my best faculties concentrated in it. My instinct tells me that my head is an organ for burrowing, as some creatures use their snout and fore paws, and with it I would mine and burrow my way through these hills. I think that the richest vein is somewhere hereabouts; so by the divining-rod and thin rising vapors I judge; and here I will begin to mine.Which of the following best describes the intended audience for this passage?A.all Americans B.the speakers philosophical contemporariesC.city dwellersD.the speakers detractorsE.highly-educated and well-to-do individualsPlease select the best answer from the choices providedABCDE Can someone please check my answer??!
