The surface area of a sphere of radius r is A = 4π*r^3.

Since the radius in this case is 8 cm (half the 17 cm diameter), the area of this sphere is

A = 4π(8 cm)^2, or 256π cm^2.

A $104.000 selling price with $24.000 down at 81/2% for 25 years results in monthly payments of
Vinil7 [7]
 The monthly payment would be $289.33

$104,000 - $24,000 = $80,000
$80,000 x %8.5 interest = $6,800
$80,000 + $6,800 = $86,800  (total being paid back)
12 (total of months in a year) x 25 (number of years) = 300
Divide $86,800 by 300 and your monthly payment is $289.33

Write an equation that you can use to find the value of x.
MariettaO [177]
Line CA is a straight line, meaning it adds up to 180°

Line BE splits the line into two supplementary angles, because when the two angles are added together they will equal 180°

Using the rule of supplementary angles, we can then make the equation 3x + 8x + 15 = 180

Now, simplify the equation by combining like terms

11x + 15 = 180

To solve, isolate x

11x + 15 = 180
11x = 165
x = 15

Angle m AOC=108° m AOB=3x+4° m BOC=8x-28°<br><br> Find m AOB
Alex787 [66]

Hello from MrBillDoesMath!

Answer:

40



Discussion:

A diagram is always appreciated!

Assuming that

mAOC = mAOB    + mBOC       =>

108      = (3x + 4)  +  (8x - 28)    =>  combine common terms

108      = (3x + 8x) + (4 - 28 )     =>

108      = 11x - 24                        =>   add 24 to both sides

132     = 11x                                 =>

x = 132/11 = 12


So mAOB = 3x + 4 = 3(12) + 4 = 36 + 4 = 40



Thank you,

MrB
