Answer:

x-9

Step-by-step explanation:

"Less than" switches the way of the expression.

If the "less than" was not there it would have been:

9-x

"Less" means subtract so you would subtract x from 9.

Hope this helped!

Find the surface area of the figure
Maurinko [17]

Answer:

Step-by-step explanation:

circumference of cylinder = πd = 5π  in

lateral area of cylinder = 5π×9 = 45π in²

Each colored face has a matching face on the other side of the figure.

green areas = 2(17×15) = 510 in²

blue areas = 2(12×17) = 408 in²

gray areas = 2(5×6) = 60 in²

yellow areas = 2(5×12) = 120 in²

red areas = 2(12×15) = 360 in²

total surface area = 45π + 510 + 408 + 60 + 120 + 360 ≅ 1,599.37 in²

Solve the following equations. Round your answers to the nearest hundredth as needed.
Mekhanik [1.2K]

Answer:

b = 1.31

Step-by-step explanation:

Step 1: Add 1.93 to both sides.

  • 9.13b-1.93+1.93=10.05+1.93
  • 9.13b=11.98

Step 2: Divide both sides by 9.13.

  • (9.13b)/9.13 = 11.98/9.13
  • b = 1.31215..

Step 3: Round to the nearest hundredth.

  • 1.31215.. ≈ 1.31

Therefore, b = 1.31.

Have a lovely rest of your day/night, and good luck with your assignments! ♡
