Firstly we need to count how much did the employees earn after the raises:

4% from $41,000 =
= 4/100 * 41,000 =
= 4 * 410 =
= 1644

4,5% from 43,700 =
= 45/1000 * 43,700 =
= 45 * 43,7 =
= 1966,5

3% from 39,700 =
= 3/100 * 39,700 =
= 3 * 397 =
= 1191

Now we need to sum up all the raises:

1644 + 1966,5 + 1191 = 4801,5

So now we can clearly see that answer A ($4,802) is the closest one to the total of all three raises.

Which three lengths could be the lengths of the sides of a triangle? A.21 cm, 7 cm, 7 cm B.9 cm, 14 cm, 22 cm C.15 cm, 5 cm, 20
lapo4ka [179]
B.) 9 cm, 14 cm, 22 cm

It would make an obtuse triangle, and by using the triangle calculator trick or ways you would have to find the area of the triangle, but it would get to confusing...

But also the simplest way or elementary would be

A.) 21 cm, 7 cm 7 cm

Area of Big Rectangle                                     Area of Small Rectangle

A = L x w                                                           A = L x w

 = (25 + 2w)(10 + 2w)                                           = 25 x 10

 =   250 + 50w + 20w + 4w²                               = 250

       Big - Small  

74 = 250 + 70w + 4w² - 250

74 = 4w² + 70w

0 = 4w² + 70w - 74

   = 2(2w² + 35w - 37)

  = 2[2w² -2w  |  +37w - 37]

  = 2[2w(w - 1) |  +1(w - 1)]

  = 2(2w + 1)(w - 1)

0 = 2                                   0 = 2w + 1                                     0 = w - 1

FALSE so disregard          w = -1/2                                         w = 1

                                         NEGATIVE so disregard

A rectangle's perimeter is equal to 27 plus its width. The length of the rectangle is four times its width. What is the
lara31 [8.8K]

Answer:

P = 3

Step-by-step explanation:

L = 4*w

P = 27 + w

P = 2*L + 2*w = 27 + w

2L = 2*(4w) = 8w

Put that into the perimeter formula (the first one.)

P = 8w + 2w = 27 + w

10w = 27 + w                        Subtract w from both sides

9w = 27                                Divide by 9

w = 27 / 9                          

w = 3

You should find the Length just so you can check it.

L = 4w

L = 4*3

L = 12

Check

P = 2L + 2w

P = 2*12 + 2*3 = 30

P = 27 + w

P = 27 + 3

P = 30 and everything checks.

How do you find the zeros of an equation​
lubasha [3.4K]

Answer:

Step-by-step explanation:

In general, given the function, f(x), its zeros can be found by setting the function to zero. The values of x that represent the set equation are the zeroes of the function. To find the zeros of a function, find the values of x where f(x) = 0.
