Answer:

x = 1, y = -1, z = 3

Step-by-step explanation:

x - 2y + 2z = 9

y + 2z = 5

z = 3

According to the last equation, z is equal to 3 so we can plug that in and our new 2 equations will be:

x - 2y + 6 = 9

y + 6 = 5

We can subtract 6 from both sides of the second equation to end up with:

y = -1

Now plugging this into the first equation, we have:

x + 2 + 6 = 9

x + 8 = 9

Subtract 8 from both sides

x = 1

Cooper is opening an online savings account to hold his $20,000 emergency fund. The online account pays 1.5% interest compounded monthly. If Cooper does not deposit or withdraw any money from the account, how much will be in the account in 25 years

Answers

Answer:

After 25 years, Cooper will have $29,093.01 in his savings account.

Step-by-step explanation:

While Cooper opened an emergency savings account of $ 20,000, which yields an annual interest of 1.5% compounded monthly, to determine how much money he will have in his account after 25 years, the following calculation must be performed:

X = 20,000 (1 + 0.015 / 12) 25x12

X = 29,093.01

Therefore, after the passage of 25 years, Cooper will have $ 29,093.01 in his savings account.

Answer:

y = 75

z = 43.3

Step-by-step explanation:

To find the value of y we use the trigonometric identity Sine.

[tex]sin\ 30 = \frac{y}{150}\\\\y=150*sin30\\y= 75\\[/tex]

Now to find the value of z we can use the trigonometric identity Tangent.

[tex]tan\ 60=\frac{y}{z}\\\\z=\frac{y}{tan\ 60}[/tex]

We know the value of y is 75 so it becomes,

[tex]z=\frac{75}{1.732} \\\\z=43.3[/tex]

Answer:

y=-150 ' z = - 468

Step-by-step explanation:

Sin angle = opp/hyp

Cos 30 = y/150

y = 150 ×( cos30)

y= - 150

Tan angles = opp / adj

Tan 60 = - 150 / Z

Z = (-150) / tan 60

Z = (-150) / 0.32

Z= - 468

You spend $63 on books and movies. You pay $12 per book and $15 per movie. You buy 3 more books than movies. How many of each item do you buy?

Answers

Answer:12B - 12M = 36

12B + 15M = 63

Subtract one from the other:

12B + 15M = 63

-(12B - 12M = 36

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

0 + 27M = 27

27M = 27

M = 1

B - M = 3 (from the original equations)

B - 1 = 3

B = 4

Step-by-step explanation:

You need to separate the 8 from each side of the equation. Picture it like this:

-104= 8 (multiplied by) x

To separate 8 from the variable, you need to divide that side by 8. Similarly, you need to do the same thing to the other side.

-104/8=8x/8

The given triangles are not similar.

What is similarity of triangles?

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion.

Given a figure of two triangles, ΔWXT and ΔYXZ

Here,

28/35 ≠ 30/38

WX/YX ≠ XT/XZ

We can conclude that, the corresponding sides are not in common ratio, so triangles are not similar.

Hence, The given triangles are not similar.

In option B , it's given that -a > -c . If we'll verify this statement , we'll find that when we put the negative sign in a , the all totla value of a becomes positive BECAUSE 'a' WAS A NEGATIVE NUMBER.

Now if we put a negative sign in c , the all total value becomes negative BECAUSE 'c' WAS A POSITIVE NUMBER.

By comparing -a & -c , we'll get to know that :-

-a > -c

The vessel does not halt. The wind blows. That sombre ship has a path which it isforced to pursue. It passes on.The man disappears, then reappears; he plunges, he rises again to the surface; he calls, he stretchesout his arms; he is not heard. The vessel, trembling under the hurricane, is wholly absorbed in its ownworkings; the passengers and sailors do not even see the drowning man; his miserable head is but a speckamid the immensity of the waves. He gives vent to desperate cries from out of the depths. What a spectreis that retreating sail! He gazes and gazes at it frantically. It retreats, it grows dim, it diminishes in size. Hewas there but just now, he was one of the crew, he went and came along the deck with the rest, he had hispart of breath and of sunlight, he was a living man. Now, what has taken place? He has slipped, he hasfallen; all is at an end.He is in the tremendous sea. Under foot he has nothing but what flees and crumbles. The billows, tornand lashed by the wind, encompass him hideously; the tossings of the abyss bear him away; all thetongues of water dash over his head; a populace of waves spits upon him; confused openings half devourhim; every time that he sinks, he catches glimpses of precipices filled with night; frightful and unknownvegetations seize him, knot about his feet, draw him to them; he is conscious that he is becoming an abyss,that he forms part of the foam; the waves toss him from one to another; he drinks in the bitterness; thecowardly ocean attacks him furiously, to drown him; the enormity plays with his agony. It seems asthough all that water were hate.Nevertheless, he struggles.He tries to defend himself; he tries to sustain himself; he makes an effort; he swims. He, his pettystrength all exhausted instantly, combats the inexhaustible.Where, then, is the ship? Yonder. Barely visible in the pale shadows of the horizon.The wind blows in gusts; all the foam overwhelms him. He raises his eyes and beholds only thelividness of the clouds. He witnesses, amid his death-pangs, the immense madness of the sea. He istortured by this madness; he hears noises strange to man, which seem to come from beyond the limits ofthe earth, and from one knows not what frightful region beyond.LES MISRABLES 114There are birds in the clouds, just as there are angels above human distresses; but what can they dofor him? They sing and fly and float, and he, he rattles in the death agony.He feels himself buried in those two infinities, the ocean and the sky, at one and the same time: theone is a tomb; the other is a shroud.Night descends; he has been swimming for hours; his strength is exhausted; that ship, that distantthing in which there were men, has vanished; he is alone in the formidable twilight gulf; he sinks, hestiffens himself, he twists himself; he feels under him the monstrous billows of the invisible; he shouts.There are no more men. Where is God?He shouts. Help! Help! He still shouts on.Nothing on the horizon; nothing in heaven.He implores the expanse, the waves, the seaweed, the reef; they are deaf. He beseeches the tempest;the imperturbable tempest obeys only the infinite.Around him darkness, fog, solitude, the stormy and nonsentient tumult, the undefined curling ofthose wild waters. In him horror and fatigue. Beneath him the depths. Not a point of support. He thinks ofthe gloomy adventures of the corpse in the limitless shadow. The bottomless cold paralyzes him. Hishands contract convulsively; they close, and grasp nothingness. Winds, clouds, whirlwinds, gusts, uselessstars! What is to be done? The desperate man gives up; he is weary, he chooses the alternative of death; heresists not; he lets himself go; he abandons his grip; and then he tosses forevermore in the lugubriousdreary depths of engulfment.Oh, implacable march of human societies! Oh, losses of men and of souls on the way! Ocean intowhich falls all that the law lets slip! Disastrous absence of help! Oh, moral death!The sea is the inexorable social night into which the penal laws fling their condemned. The sea is theimmensity of wretchedness.The soul, going down stream in this gulf, may become a corpse. Who shall resuscitate it?"
