What is the length of the hypotenuse?

Answers

Answer:

50ft

Step-by-step explanation:

use the Pythagorean theorem 14 squared + 48 squared equals 2500 square root of 2500 equals c squared the square root of 2500 is 50

Answer:

50

the Pythagorean theorem states that the hypotenuse of a triangle squared is equal to the sums of the other 2 sides squared.

it can be expressed as so:

c^2=a^2+b^2

therefore

c^2=14^2+48^2

C^2= 196+2304

c^2=2500

square root of 2500 is 50

50=the hypotenuse.

If R is the midpoint of TS, TR = 5x - 12, and RS = 3x + 8, find TS.

Answers

Answer:

5x -12 = 3x +8 (set the two = each other because they are the same length)

2x- 12= 8 (subtract 3x from both sides)

2x = 20 (add 12 to both sides)

x=10 (what x= for both expressions)

5(10) -12 (plug it into the first one to see what the length is and to see they're =

50 - 12 ( I already multiplied, now subtract)

38 (what the length of TR is)

3(10) +8 (plug it in again but into the other expression)

30+8 (multiply and add)

38 (the two have the same answer, so the x-value is correct.)

38+38= 76 (add the lengths of RS and TR and you get the length of TS)

Step-by-step explanation:

I hope this helps :)

Applying the segment addition theorem, the value of TS is: 76

Given:

TR = 5x - 12

RS = 3x + 8

If T is the midpoint of TS, therefore we would have the following equation:

TR = RS

Plug in the expressions

5x - 12 = 3x + 8

Add like terms together

5x - 3x = 12 + 8

2x = 20

Divide both sides by 2

x = 10

TS = TR + RS (segment addition theorem)

Substitute

TS = 5x - 12 + 3x + 8

Plug in the value of x

TS = 5(10) - 12 + 3(10) + 8

TS = 50 - 12 + 30 + 8

TS = 76

-1/2x + 2 = -x + 7

multiply by 2 so that -1/2x becomes -x

(-1/2x + 2 = -x + 7)2

-x + 4 = -2x + 14

subtract 4 from both sides

-x = -2x + 10

add -2x to both sides

x = 10

Add them together first. You get in total 18. So that’s your base number. Then add the white balls that is 10 and the pink balls that is 3. The reason why I don’t add the 5 yellow balls is because they are not mentioned in the third sentence. When you added those you will end up with 13/18.

How many solutions does 46x– 23 = 46x + 23 have

Answers

Answer:

no solution

Step-by-step explanation:

Let's first try to solve this.

Notice that there is a 46x term on both sides, so we can subtract both sides by 46x, leaving us with:

-23 = 23

Well... this is a false statement: -23 does not equal 23.

Thus, this as no solution.

Answer:

No solutions found

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

46*x - 23 - (46*x + 23) = 0

Equations that are never true

Solve : -46  =  0

This equation has no solution.

a dozen roses costs $21 at this rate, how much would you expect for four roses​

Answers

Answer:

$7

Step-by-step explanation:

Divide 21 by 12 which equals 1.75. Multiply by 4 and it's 7.

The cost of four roses is $7.

Given that, a dozen roses costs $21.

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

We know that, in one dozen there will be 12 roses.

Now, cost of one rose = 21/12

= $1.75

So, cost of 4 roses = 4×1.75

= $7

Therefore, the cost of four roses is $7.

Step-by-step explanation:

Random variation in a process indicates stability; whereas non-random variation indicates process instability.

When there is random variation in a process, it means that the process is stable and under control such that the only variations are those expected to be in the process.

When the variation is non-random however, it points to instability in process because this variation is special and not inherent in the process.
