Find the value of x. Write your answer in simplest radical form, if necessary.

Answers

x^2 = 25^2 - 22^2 <=>

x^2 = 625 - 484 <=>

x^2 = 141 <=>

x = 11.9

The value of 'x' or the length of the base of the triangle is [tex]\sqrt{141}[/tex] units.

What is a triangle?

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know, In right-angled triangle, the sum of the squares of the smaller two sides of a right-angle triangle is equal to the square of the largest side.

The given triangle has a hypotenuse of 25 units and a height of 22 units.

Therefore,

Hypotenuse² = Base² + Height².

Base² = Hypotenuse² -  Height².

Base = [tex]\sqrt{Hypotenuse^2 - Height^2}[/tex].

Base = [tex]\sqrt{25^2 - 22^2}[/tex].

Base = [tex]\sqrt{625 - 484}[/tex].

Base = [tex]\sqrt{141}[/tex].

So, The length of the base is [tex]\sqrt{141}[/tex] units.

write a rational number which has no reciprocal or multiplicative inverse.​

Answers

Answer:

0.

Step-by-step explanation:

0 is the only number that has no reciprocal or multiplicative inverse.

A reciprocal / multiplicative inverse of a number means a number that when multiplied by the original number will equate to 1.

However, no matter what you multiply with 0, it will never be 1.

Hence, the answer is 0.

Answer:

68, 17, $17

Step-by-step explanation:

filling in the first blank using the chart. Money made for 4 sweatshirts is $68

68/4=17, this is the unit price, meaning the amount it would cost for one sweatshirt. Thats where we get the next blank's answer. 17/1 and since we found the unit price, we already answered the last question, $17 per sweatshirt.

Because Kendall's business spent more money than it collected, the business's balance sheet showed a balance of -$1,280$ at the end of the month. The next day, Kendall's business spent $560 on new tools. Part A Kendall determines that the new balance is -$720 because 1,280 + 560 = -720 . Did Kendall correctly determine the new balance? Explain why or why not. If not, calculate the new balance. Respond in the space provided.

Answers

Answer: No. Kendall did not correctly determine the new balance. The new balance is -$1840.

Step-by-step explanation:

From the question, we are informed that Kendall's business spent more money than it collected, and therefore the business's balance sheet showed a balance of -$1,280 at the end of the month. We are informed that the next day, Kendall's business spent $560 on new tools.

Therefore, since Kendall made a purchase, this is an expense and we have to subtract it from the previous balance. This will be:

= -$1280 - $560

= - $1840

The new balance is -$1840

Answer:

She is not correct. The correct answer should be -$1840

Step-by-step explanation:

Explanation: Kendal is ultimately wrong, because in his step in adding the $560 spent on new tools, she had added a positive number, which meant they deposited money to go out of debt. Instead he was supposed to subtract the $560, or even add -$560 to the businesses balance. If calculated correctly, by subtracting $560 to the current balance, it would get us to -$1840.

how many solution does following equtitions have 7x+21=21

Answers

One solution.

[tex]7x + 21 = 21 \\ 7x = 21 - 21 \\ 7x = 0 \\ x = 0[/tex]

If we can solve for the value of x. Then the solution would be one only for system of linear equations.

For your information, When the equation is true or rather say that both sides are the same, the solution will be infinite.

When the equation is false or rather say that both sides have different number or value then there won't be any solutions.

The answer to the question above is he needs a minimum of 117 tickets to reach his goal

Step-by-step explanation:

This is true because of the at-the-door tickets it shows on graph 116.667, and in order to find the minimum amount we need to round, and in this case round up, thus when we round we are left with 117, therefore providing you with your answer 117.

Therefore, the coordinates of the vertices of ΔA'B'C' after the dilation with a scale factor of 2.5.

A'(-5, -2.5)B'(2.5, 5)C'(5, -10)

Step-by-step explanation:

Given the vertices of ΔABC

A(-2, -1)B(1, 2)C(2, -4)

Given that ΔA'B'C' is a dilation of ΔABC with a scale factor of 2.5 and the center of dilation (0, 0).

We know that when the scale factor > 1, then the image is enlarged.

The formula to determine the dilation with a scale factor of 2.5.

P(x, y) → P'(2.5x, 2.5y)

Here, P' is the image of P, and the vertices of the image is dilated by a scale factor of 2.5.

In other words, the vertices of the image can be obtained by multiplying the vertices of the original triangle with 2.5.

Thus,

P(x, y) → P'(2.5x, 2.5y)

A(-2, -1) → P'(2.5(-2), 2.5(-1)) = A'(-5, -2.5)

B(1, 2) → B'(2.5(1), 2.5(2)) = B'(2.5, 5)

C(2, -4) → C'(2.5(2), 2.5(-4)) = C'(5, -10)

Therefore, the coordinates of the vertices of ΔA'B'C' after the dilation with a scale factor of 2.5.

A'(-5, -2.5)B'(2.5, 5)C'(5, -10)

The supplement of an angle is three times the measure of the angle.

What is the measure of the angle?

The measure of the angle is degrees.

The measure of the supplement of the angle is degrees.

Answers

Answer: The angle equals  45 ∘  and the supplement is  135 ∘

Explanation:

Since the supplement is three times the angle, we can say    s  =  3 a

Since we know the supplement is  

180 − a , we can plug that in.

180 - a = 3a

180  = 4 a  (add  a  to both sides)

45  =  a  (divide both sides by  4)

Since we know the angle now, all we have to do is multiply it times  3  to find the supplement.

45  ×  3  =  135

A.It is barely visible to humans. B.It has rough sections. C.It is unusually narrow. D.It has hidden dangers.here is the passage Young Hunter's feet moved him along the trail, but his thoughts kept pulling him back toward the village. There was too much to think about, too much to understand. He tried to concentrate on the simple task of placing one foot in front of the other. The big dog's right shoulder was almost touching Young Hunter's left thigh as it turned its head up to look into Young Hunter's face. Young Hunter slapped his hand affectionately on Agwedjiman's back. He could no longer hear the sounds of the dog's two brothers on the trail ahead. They were scouting the way, silent as wolves. Now and then, one would look back from around a bend or would slip quietly out of the brush by the side of the trail to walk with them a short space before trotting on ahead once more. Truly, when a man was with his dogs he was not alone."Agwesis," Young Hunter said, speaking the dog's pet name, "you guard me well. But you cannot guard me from my thoughts. I am all right. Don't worry. But it is fortunate for me that you and your brothers are watching the way for me. This morning I'm like a puppy whose eyes have just begun to open. Like someone who has stared too long into the sky and is now half-blinded by the light." Young Hunter stroked the big dog's head and it whined with happiness.Young Hunter shifted his pack. He began to walk more purposefully. He would reach the village of the Salmon People before night. There he would be given the second half of the secret of the Long Thrower. He hefted the bundle that he carried in his hand. It was wrapped tightly in a skin decorated with Bear Talker's symbols.Now, Young Hunter thought, I will shape my thoughts toward the work ahead of me. I will not let them wander in circles like the water beetles that spin on the surface. But even as he thought that, he wondered if the heroes of the old stories ever felt as uncertain as he did on this morning. Did Long Hair or the One Who Shaped Himself ever feel confused about whether to go on or return home? They were challenged by monsters and they defeated them. They were attacked by evil magic and overcame it. But in none of those stories was it ever mentioned that those heroes found it hard just to keep walking, one slow step at a time, toward a destination they couldn't name. x/5 = 8/9 what is x Robins feed on earthworms, which live in moist soil.
