11111nata11111 [884]

Answer:

Edison will be paid $15,112 for 3 months

Step-by-step explanation:

Edison receives an annual fixed pay = $45,448.

Monthly pay  = 45,448/12 = $3787.33

3-month salary = $3787.33 *3 = $11.362

Commission = 15%

Total sale = $25,000 for the first 3 months.

Commission amount = 25,000*0.15 = $3750

Therefore, total pay that Edison received during first 3 months= salary + commission

= $11,362 + $3750

= $15,112

Thank you.

x,y, and z to the nearest tenth .(hint: use altitude and leg rules) PLEASE HELP FAST !!! please solve and show steps
madreJ [45]

Use the Pythagorean theorem to find z:

z = √(6^2 + 9^2)

z= √(36 + 81)

z = √117

z = 3√13 = 10.8

Use leg rule to find x:

x/6 = 6/9

Cross multiply:

9x = 36

Divide both sides by 9:

x = 36/9

x = 4

Use Pythagorean theorem to find y:

y = √(6^2 + 4^2)

y= √(36 + 16)

y = √52

y = 2√13 = 7.2

Which expression is the simplest form of 2x^3 - x^2 + 3 (x^3 - 4x^2)
jolli1 [7]

The simplest form of the given expression is 5x^3-5x^2.

We have given that

2x^3 - x^2 + 3 (x^3 - 4x^2)

We have to determine the simplest form of the given expression.

<h3>What is the distributive property?</h3>

The distributive property of binary operations generalizes the distributive law, which asserts that equality is always true in algebra. elementary.

Use the distributive property we get,

2x^3 - x^2 + 3 (x^3 - 4x^2)\\=2x^3 - x^2 +3x^3-12x^2\\

Add like terms we get,

Therefore we get,

=5x^3-5x^2

Therefore the simplest form of the given expression is 5x^3-5x^2.

(3) In the following circle and rectangle, when AB (the length of segment AB) is 3, BC is 3, and DE is 2.5, find the length of E
dusya [7]
I think that the length of DE is 4.  you can add 0.5 to each side of BC in order to find the length of EF since EF starts 0.5 before BC does and therefore also ends 0.5 after BC since the circle is symmetrical.
