commission expense is budgeted to be $16,000 at a planned sales level of 4,000 units. if only 2,900 units are sold, how much commission expense will appear on the flexible budget, and is the activity variance favorable or unfavorable?

Answers

The amount of commission expense that will appear on the flexible budget if 2900 units were sold is; $11600

The activity variance is favourable.

According to the question;

The budgeted commission expenses is to be $16,000 at a planned sales level of 4,000 units.However, only 2900 units are sold.

To solve this;

We must be aware that the commission expense is directly proportional to the number of units sold.

In essence;

$16,000 is expected at 4,000 units of sale.Therefore, $x is expected at 2,900 units of sale.

By cross product;

x = (2900 × 16000)/4000

x = $11,600

Ultimately, the activity variance is favourable bas less commission expense is recorded for less sale.

Answer:

x=5

Step-by-step explanation:

x^2+25-10x = x^2-25

-x^2 -x^2

25-10x = -25

-25 -25

-10x = -50

x=5

lets check

(5-5)^2 = 5^2-25

0^2 = 25-25

0 = 0

Answer:

x = 5

Step-by-step explanation:

(x - 5)^2 = (x - 5) (x - 5) =

x^2 -10x + 25 = x^2 - 25

x^2 - x^2 - 10x + 25 = - 25 (x^2 - x^2 = 0)

- 10x + 25 = - 25

- 10x = - 25 - 25

x = - 50/- 10

x = 5

Answer:

a=58

Step-by-step explanation:

32+a=90

32-32+a=90-32

a=58

90-32 is 58 so the missing degree is 58. The reason we use 90 first as the small box, indicates it’s a right angle thus being 90 degree and if one side is 32, then the other side must be enough to add up to 90 so 58 and 32 equal 90

Hamish buvs a new car for $20000

Work out the value of the car at the end of 3 years.
Give your answer to the nearest $

Answers

Answer:

The correct answer is $10,629

Step-by-step explanation:

Here is how I got it!

First, you will have to borrow the 20,000 from the word problem.

Next, multiply 20,000 with 0.81 with the power of 3

[tex]20,000*0.81^3=n[/tex]

The 3 is the number of years, n is the nearest $ answer.

First, do [tex]0.81^3[/tex]

[tex]0.81*0.81*0.81=0.531441[/tex]

(Wow, that's a crazy number!)

With 0.531441, multiply it with 20,000

[tex]20,000*0.531441=10628.82[/tex]

10,628.82 is technically (in money) $10,628.82 (with .82 being eighty-two cents).

Finally, it states to answer to the nearest $.

Just round up the .82 to 1 dollar which will just add one more dollar to 10,628

[tex]10,628[/tex] ⇒ [tex]10,629[/tex]

Add you $ symbol

With the result being: $10,629

Answer:

$10629

Step-by-step explanation:

First you have to work otu the percentage decrease:

100 - 19 = 81

81/100 = 0.81 (/ means divide)

Then you have to work the amount after 3 years:

Long Method

20000 x 0.81 = 16200

16200 x 0.81 = 13122

13122 x 0.81 = 10628.82

or Short Method

20000 x 0.81³ = 10628.82

Finally you round it to the nearest $:

10628.82 ⇒ 10629

Can someone help me do this

Answers

The 3 inside angles should add up to 180. The one next to the 130 is 50 degrees.

180 = 50 + (16x + 4) + (14x + 6)

180 = 30x + 60

120 = 30x

x = 4

x = 4

First, we can see that the top angle is 130°, that means the other side of the angle is 50° because that straight line must equal 180°.

Next, we know that the inside of a triangle must equal 180°. We know that one of the angle’s is 50°, that means we need to plug in the numbers and solve the other angles until the total of all three angles is 180°.

If we plug in 4 for x, this is what we get…
14(4) + 6 = 62°
16(4) + 4 = 68°

Now we know all three angles, but we can add to check…
50° + 62° + 68° = 180°

Therefore, x = 4!

Linda is twice as old as Vera. Tanya is four less than four times the age of Linda. Their total age is two more than nine times the age of Vera. How old is Tanya, in years?

Answers

[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]

Let the age of Vera be x,

Linda's age = 2x

Tanya's age = (4 × 2x) - 4 = 8x - 4

Total Age = 9x + 2

so, let's Solve for x :

[tex]x + 2x + 8x - 4 = 9x + 2[/tex]

[tex]11x - 4 = 9x + 2[/tex]

[tex]11x - 9x = 2 + 4[/tex]

[tex]2x = 6[/tex]

[tex]x = 3[/tex]

Age of Tanya :

[tex]8x - 4[/tex]

[tex]24 - 4[/tex]

Tanya's age is 20 years.

Step-by-step explanation:

15 1/2+ 3/4=16 1/4

to add fractions what you want to do is this:

so you want them as the same denominator, a way to do this is multiply one denominator with another (ex, 2 in 1/2. you want to multiply 4 with 2 which equals 8 and 2 with 3. this together equals 6/8. do the same thing with 1/2. 1×4=4 2×4=8. 4/8)

so, whats 4/8 and 6/8? just adding it like usual, it'll be 10/8, or 1 2/8.

15+1 2/8=16 2/8

16 2/8 simplified (just divide by 2 until you make it to where you cant anymore)

16 1/4

do the same with the other adding ones.

23 1/6+8 3/4=23 11/12

15 2/5+ 2 2/6= 17 11/15

now, do the same way as showed before but except subtract.

9/10 - 3/5 = 15/50

7 3/4 - 5 5/8 = 1/8

20 5/8= 1/8
