CAN YOU HELP ME WITH THIS EXERCISE: 3(x6) + 8 = 5(x-5)-1

Answers

X= -1. That’s the answer for this

Answer:

Step-by-step explanation:

3(x6) + 8 = 5(x-5) - 1

we move all the terms to the left:

3(x6) + 8 -(5(x-5) -1 ) = 0

We add all the numbers together, and all the variables:

3x^6 - ( 5 ( X-5) - 1) + 8 = 0

We calculate terms in parentheses: - ( 5 ( x-5) - 1 ) , so :

5(x-5)-1

we multiply:

5x - 25 -1

we add all the numbers together, and all the variables:

5x - 26

back to the equation:

- ( 5 x - 26)

a certain coin is a circle with a diameter of 18mm. What is the exact area of either face of the coin in terms of pi (3.14)

Answers

Answer:

254.34 mm².

Step-by-step explanation:

For this problem, we use the formula to find the area of a circle, which is[tex]A=\pi r^2[/tex] . [tex]r[/tex] is the radius, which we can find by dividing the diameter by 2 and [tex]\pi[/tex] in this case is 3.14.

[tex]A=\pi r^2\\A=3.14*(18/2)^2\\A=3.14*9^2\\A=3.14*81\\A=254.34[/tex]

Therefore, the area of either face of the coin is 254.34 mm².

Find the geometric mean of sqrt 77 and sqrt 343.

Answers

Answer:

12.75

Step-by-step explanation:

The computation of the geometric mean of sqrt 77 and sqrt 343 is given below:

As we know that

Geometric mean = [tex]\sqrt{ab}[/tex]

where

a is the first number = [tex]\sqrt{77}[/tex]

And, the b is the second number = [tex]\sqrt{343}[/tex]

Now first we have to convert into a number

For a it, is = 8.78

And, for b, it is = 18.52

Now the geometric mean is

[tex]= \sqrt{8.78 \times 18.52}[/tex]

= 12.75

Answers

Answer:

25.1mm²

Step-by-step explanation:

Total surface area of a cylinder = 2πr(r+h)

r is the radius = 1.2mm

h is the height = 2mm

Substitute

TSA = 2(3.14)(1.2)[1.2+2]

TSA = 7.536[3.2]

TSA = 24.1152
