ad-work [718]
To solve for the materials quantity variance, we have the formula below:
Materials Quantity Variance = (Actual Quantity Used * Standard Rate) - (Standard Quantity Allowed * Standard Rate)

The solution is shown below:
Materials Quantity Variance = ($9.20 - $9.00)*3400
Materials Quantity Variance = $680

The answer is $680.

How do i solve this inequality and what is the answer? <br> solve for x: -3x +3 &lt; 6
kap26 [50]

Answer:

x > -1

Step-by-step explanation:

-3x +3 < 6

-3x < 6 - 3  (subtract 3 from both sides)

-3x < 3   (divide both sides by 3)

-x < 1 (multiply both sides by -1, remember to flip the inequality when multiplying both sides by negative numbers)

x > -1  (answer)

Give triangle ABC is a right triangle, and angle A is the right angle. If sin(B)=3/5, find the cos(B).
hichkok12 [17]

Answer:

Cos B = 4/5

Step-by-step explanation:

From the question given above, the following data were obtained:

Sine B = 3/5

Cos B =?

Recall:

Sine B = Opposite / Hypothenus

Sine B = 3/5

Therefore,

Opposite = 3

Hypothenus = 5

Next, we shall determine the Adjacent. This can be obtained as follow:

Opposite = 3

Hypothenus = 5

Adjacent =?

Hypo² = Adj² + Opp²

5² = Adj² + 3²

25 = Adj² + 9

Collect like terms

Adj² = 25 – 9

Adj² = 16

Take the square root of both side

Adj = √16

Adjacent = 4

Finally, we shall determine Cos B. This can be obtained as follow:

Hypothenus = 5

Adjacent = 4

Cos B =?

Cos B = Adjacent / Hypothenus

Cos B = 4/5

Mike wants to save $1,750 in the next 12 months. He plans to save $150 each month for the first 11 months.
podryga [215]

Answer:

$1650

Step-by-step explanation:

Based on the question, we don't need the information that Mike wants to save 1750 in 12 months.

We just need to focus on how he is saving 150 every month, for 11 months.

150*11=1650

He will save $1650 if he saves $150 every month for 11 months.
