Answer:

t = 10.9

Step-by-step explanation:

9.3-t=-1.6

Subtract 9.3 from each side

9.3-t-9.3=-1.6-9.3

-t =-10.9

Multiply each side by -1 to find t

t = 10.9

The value of T is 10.9.

To find this, you must first get T on a side by itself. To do so, subtract 9.3 from both sides. This leaves -t = -10.9. Finally, divide both sides by -1, to make T positive. Thus meaning T = 10.9.

Heres an image to show how I solved the problem. I hope this helps!

Surface area of a cylinder. (see attached image please)
Zolol [24]

Answer:

\large{ \tt{❃ \: EXPLANATION}} :

  • Firstly you need to remember the formula to find out surface area of a cylinder - Surface area of a cylinder = 2πr ( r + h ) where r is the radius of a circular face and h is the height of the cylinder.

  • We're provided : Diameter of cylinder = 12 which means radius ( r ) = 6 cm [ Radius is the half of diameter ] & Height ( h ) = 25 cm & we know pi ( π ) = 22/7.

\large{ \tt{❁ \: LET'S \: SOLVE}} :

\large{\boxed{  \tt{☄TOTAL \: SURFACE \: AREA \: OF\: CYLINDER= 2\pi \: r \: ( \: r + h)}}}

- Plug the values & then simplify !

\large{↦2 \times  \frac{22}{7}  \times 6(6 + 25) }

\large{↦2 \times  \frac{22}{7}   \times 6 \times 31}

\boxed{\large{↦1169.14  \: \tt{ {cm}^{2} }}}

  • Hence , The surface area of given cylinder is 1169.14 cm²

Need help with this question
Ne4ueva [31]

Answer:

About 3%

Step-by-step explanation:

It decreased.

3% of 465056=13951

465056-13951=451105

3.6% of 465056=16742

465056-16742=448314

The amount you want it 450678 and 451105 is closer to 450678 than 448314.

Solve <br> 3x – y + 2z = 6<br> -x + y = 2 <br> x – 2z = -5
posledela

Answer:

Step-by-step explanation:

3x – y + 2z = 6 - - - - - - - - - 1

-x + y = 2 - - - - - - - - - - - - -2

x – 2z = -5 - - - - - - - - - - - -3

From equation 2, x = y - 2

From equation 3, x = 2z - 5

Substituting x = y - 2 and x = 2z - 5 into equation 1, it becomes

3(y - 2) – y + 2z = 6

3y - 6 - y + 2z = 6

3y - y + 2z = 6 + 6

2y + 2z = 12 - - - - - - - - - 4

3(2z - 5) – y + 2z = 6

6z - 15 - y + 2z = 6

- y + 6z + 2z = 6 + 15

- y + 8z = 21 - - - - - - - - - - 5

Multiplying equation 4 by 1 and equation 5 by 2, it becomes

2y + 2z = 12

- 2y + 16z = 42

Adding both equations

18z = 54

z = 54/18 = 3

Substituting z = 3 into equation 5, it becomes

- y + 8×3 = 21

- y + 24 = 21

- y = 21 - 24 = - 3

y = 3

Substituting y = 3 into equation 2, it becomes

-x + 3 = 2

- x = 2 - 3 = -1

x = 1
