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.
Answer:
Let's simplify step-by-step.
3x2+9x+6−(8x2+3x−10)+(2x+4)(3x−7)
Distribute:
=3x2+9x+6+−8x2+−3x+10+(2x)(3x)+(2x)(−7)+(4)(3x)+(4)(−7)
=3x2+9x+6+−8x2+−3x+10+6x2+−14x+12x+−28
Combine Like Terms:
=3x2+9x+6+−8x2+−3x+10+6x2+−14x+12x+−28
=(3x2+−8x2+6x2)+(9x+−3x+−14x+12x)+(6+10+−28)
=x2+4x+−12
Answer:
=x2+4x−12
Answer: 5 s
Step-by-step explanation:
Given
Height of the rocket can be modelled as 
Rocket will land on earth when it's height becomes 0
Neglecting 0 value
Thus, rocket remains in air for 5 s.
Answer:
b. 5
Step-by-step explanation:
10x+18≤-12
10x≤-30
x≤-3
anything less than or equall to -3 is an option therefore it is b
Answer:
A coefficient is the number that the variable is multiplied by.
The variable is the unknown value, often represented by a letter or symbol.
The constant is the number that is not affected by a variable value, hence the term "constant."
Using the logic above, we can conclude that 4 is the coefficient, x is the variable, and -12 is the constant.
