Answer: 11.375°

Step-by-step explanation:

55 + (4x + 17) + (4x + 17) = 180°    Set up equation

4x + 4x + 55 + 17 + 17 = 180°    Commutative Property of Addition

8x + 89 = 180°    Combine like terms

8x = 91°    Subtract 89 from both sides

x = 11.375°   Divide both sides by 8

Not entirely sure about this one; you might have to round the answer.

If the sales tax rate in Perryville
TEA [102]
To find the tax rate (in this case, 8%), you must multiply the base cost ($128) by the percentage (or, divide the cost by 100 and multiply that by the percentage).

$128÷100=$1.28

$1.28×8%=$10.24

So, the amount of tax that is charged on the table is exactly $10.24.

Hope this helps!

A cylinder has a height that is 2 times as large as its radius. The lateral area of the cylinder is 16π square units. What is th
Juliette [100K]
The length of the radius of the cylinder is 2 units.

The lateral surface area of a cylinder = <span>2πrh</span>
where, r = base radius
            h = height of cylinder
Now, height of cylinder = 2r units
          
⇒ 16 π =  2×π×r×<span>h
</span>⇒ 16 π =  2×π×r×2r
⇒  r^{2} = 4
⇒ r = 2 units
Thus, radius is 2 units.

The sum of a number and 72 times its reciprocal is -17. Find the number
butalik [34]
Let, the number = x

Then, x + 72/x = -17

x² + 72 = -17x

x² + 17x + 72 = 0

x² + 8x + 9x + 72 = 0

x(x + 8) 9(x + 8) = 0

(x + 8)(x + 9) = 0

x = -8 OR -9

In short, Your Number would be: Either -9 or -8

Hope this helps!
