Use algebra.

Let the number of stickers each had in the beginning = x stickers.

Ray lost 10 we represent this by

x - 10 ( = no. stickers he has now)

Tom bought 200 so the number of stickers he now has

= x + 200

Rays has 1/4 as much as Tom so we can now create the equation

1/4(x + 200) = x - 10

Soling for x:-

1/4 x + 50 = x - 10

60 = 3/4 x

x = 60 * 4/3 = 80

Answer they had 80 stickers at first.

True or false: The variable overhead rate variance uses the same basic formula as the labor rate variance except that the variab
Zanzabum

Answer:

True

Step-by-step explanation:

The variable overhead rate variance refers to the difference in two variables.

The Variables are

1. The actual variable manufacturing overhead

2. The expected variable overhead given the number of hours worked

Labor rate variance is evaluated by

AH(AR - SR)

AH = actual hours

AR = actual rate

SR = standard rate.

The variable overhead rate variance is also calculated the same way except that it replaces the direct labor rates with variable overhead rates

stepladder [879]

Answer:

-1/8

Step-by-step explanation:

lim x approaches -6     (sqrt( 10-x) -4) / (x+6)

Rationalize

   (sqrt( 10-x) -4)      (sqrt( 10-x) +4)

    ------------------- * -------------------

       (x+6)                 (sqrt( 10-x) +4)

We know ( a-b) (a+b) = a^2 -b^2

a= ( sqrt(10-x)   b = 4    

(10-x) -16

-------------------

(x+6) (sqrt( 10-x) +4)    

-6-x

-------------------

(x+6) (sqrt( 10-x) +4)

Factor out -1 from the numerator

-1( x+6)

-------------------

(x+6) (sqrt( 10-x) +4)

Cancel x+6 from the numerator and denominator

-1

-------------------

(sqrt( 10-x) +4)

Now take the limit

lim x approaches -6    -1/ (sqrt( 10-x) +4)

                                      -1/ (sqrt( 10- -6) +4)

                                      -1/ (sqrt(16) +4)

                                      -1 /( 4+4)

                                        -1/8
