$30 + $35 = $65
Assuming tax is on whole sale not each item:
$65 * 0.06 (6%) = $3.90 (6% of $65)
$65 + $3.90 = $68.90 ($65 + 6%)
OR
You could combine both of these steps and just use this working:
$65 * 1.06 (106%) = $68.90 (106% of $65)
Answer:
2500 kg
Step-by-step explanation:
Given:
• Force produced by the truck = F = 15,000 Newtons Acceleration of the truck = a = 6 m/s²
To find:
Mass of the truck if force is 15000 newtons and acceleration is 6 m/s²
Formula:
Force = Mass Acceleration
Substituting the above values:
15000N Mass×6
Mass = 15,000/6
Mass = 2500 kg
Answer: A
Step-by-step explanation: when Constructing a confidence interval, it is important to take note of the margin of error which is given by the formulae below
Margin of error = critical value × σ/√n.
Where n is the sample size.
As we can see that the critical value is a constant and the population standard deviation.
Hence there is an inverse relationship between margin of error and sample size, which implies that a large sample size produces a small margin of error.
If the margin of error is small, it means the sample size will increase the like hood that the sample is a good representation of the population.
Answer:
Step-by-step explanation:
Coterminal angles are angles in standard position (angles with the initial side on the positive x -axis) that have a common terminal side. For example 30° , −330° and 390° are all coterminal.
Simplify the left side. 0.02x+(40-0.1x)=0.42x
-0.08x+40=0.42
since 0.42x contains the variable to solve for, move it to the left side of the equation by subtracting 0.42x from both sides
-0.08x+40-.0.42x=0
-0.5x=-40
x=80
