find the length of the missing side of the right triangle.​

Answers

Here you are trying to find the hypotenuse. So you would take
5^2 (five squared) plus 12^2 (twelve squared) and add them using the equation a^2+b^2= c^2. Now you square 5 and 12 to get 25 and 144. You add them together and get 169. Take the square root of 169 and c. The square root on c will cancel out the squared (to the power of two) part leaving you with just c. And the square root of 169 is 13. So c (the missing length) is 13. C=13.

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{13 \: \: units \: }}}}}[/tex]

Step-by-step explanation:

Perpendicular ( p ) = 5

Base ( b ) = 12

Hypotenuse ( h ) = ?

Finding the length of missing side

Using Pythagoras theorem

[tex] \boxed{ \sf{ {h}^{2} = { p}^{2} + {b}^{2} }}[/tex]

plug the values

⇒[tex] \sf{ {h}^{2} = {5}^{2} + {12}^{2} }[/tex]

Evaluate the power

⇒[tex] \sf{ {h}^{2} = 25 + 144}[/tex]

Add the numbers : 25 and 144

⇒[tex] \sf{ {h}^{2} = 169}[/tex]

Squaring on both sides

⇒[tex] \sf{ \sqrt{ {h}^{2} } = \sqrt{169}} [/tex]

Calculate

⇒[tex] \sf{ {h} = 13 \: units}[/tex]

Match the inequality with its symbolic form.
x>5
A number is larger than 5.
x 25
A number is below 5.
X35
A number is not less than 5.
*<5
A number is at most 5.

Answers

Answer/Step-by-step explanation:

The following inequalities can be translated and matched as follows:

1. A number is larger than 5:

Let that number be x. Numbers that are larger than 5 are 6, 7, 8 and so on. Therefore, the number that is larger is greater than 5. This can be represented in the symbolic form as:

x > 5

2. A number is below 5:

Numbers that are below 5 are 4, 3, 2 and so on. Therefore, we can say the number, x, is less than 5. This can be written in symbolic form as:

x < 5

3. A number is not less than 5:

A number that is not less than 5 could equal 5 or any other number that is larger than 5. Therefore, we can say the number, x, equals 5 or greater than 5. This can be written as:

x ≥ 5

4. A number is at most 5:

At most 5, means the number, x, is either 5 or less than 5. This can be written as:

x ≤ 5

How is the intersection point of two linear functions related to solving
a linear equation?

Answers

Answer:

Linear equation formed by equating both functions is used to find the x-coordinate of the intersection point.

Step-by-step explanation:

If we have two linear functions f(x) and g(x) which are intersecting at a point (a,b), then equating both functions we get a linear equation as

[tex]f(x)=g(x)=y[/tex]

On solving this linear equation we get the x-coordinate of the point of intersection, i.e., x=a.

After that, we need to substitute x=a in either f(x) or g(x) to get the y-coordinate of the point of intersection.

Therefore, the linear equation formed by equating both functions is used to find the x-coordinate of the intersection point.

Answers

Answer:

The correct option is Segment Addition Postulate

Step-by-step explanation:

The segment addition postulate states that where there are two points on a line A and C and a third point B can only be located on the line segment AB if and only if the the distances between point A and point B as well as the distance between point B and point C satisfy the equation AB + BC = AC

Therefore, given that in the figure,  the point B is in between point A and point C on segment AC then AB + BC

Similarly, AD = AE + ED.

To solve these you have to plug in the numbers into the equations. For example take the question g(9) + f(4). To solve this you have to think that the number 9 replaces the letter x in the g(x) equation and the number 4 replaces the letter x in the f(x) equation.
Once you plug in the numbers, you can solve each equation separately. You’ll see that g(9) is equal to 757 and f(4) is equal to 51.
Now since the question is asking for g(9)+f(4) you can now do 757+51 which is equal to 808.

I hope I got all the numbers right, but if I didn’t you get the point.

Kens prediction temperature for April 7C. His prediction for May is 2C higher than April. He use the number line to solve the problem, starting at zero, moving right to seven, and then moving to units to the left. Explain Ken's error

Answers

Answer:

Step-by-step explanation:

Given that:

Ken's prediction temperature for April 7C.

His prediction for May is 2C higher than April.

He attempts to use the number line to solve the problem.

On a number line, we have the origin at a given point zero, the positive x-axis to the right side, and the negative x-axis to the left side.

So, if Ken's starts from zero and move right to seven and the move units to the left, the error he made was moving 2 units to the left because he supposed to have continued in the right direction by moving 2 units forward. This is because moving to the left side will showing a decrease in the temperature by -2° C and he intends to have 2° C.

A Farmer picks 242 apples on Monday and 118 apples on Tuesday. On Wednesday, she sells 109 of the apples at the market. Which equation can be used to find a, the number of apples of farmer has left?

Answers

Answer:

the farmer has 242 apples left

Step-by-step explanation:

A = awnser

M= Monday

T= Tuesday

M= 242

T= 109

W = amount sold or 109

(M+T)-W= total amount left

use order of operations and add whats in the (   )

( 242+109 ) = 351 or ( M+T )

then you would use the sum of ( M+T ) and subtract W or 109 wich would then equal 242 so the equation

( 242+109 ) - 109 would equal 242 or ( M+T ) - W = A

Answers

Answer:

(The -n and +n cancel out, on the right side of the equation)

a+n=m

(Now subtract a from both sides)

a+n-a=m+a

(The +a and -a cancel out, on the right side of the equation)

n=m+a

Answer:

[tex]\huge \boxed{n=-a+m}[/tex]

Step-by-step explanation:

[tex]a=m-n[/tex]

Adding [tex]n[/tex] to both sides.

[tex]a+n=m-n+n[/tex]

As you can see here, there's an extra x in this problem compared to the last problem, but lets still work it out

6x*x-6
