Chrissy's vacation would have been 5 days total. To find this, you can set up a proportion. I did 40 over 100, (40%), equals 2 over x. You cross multiply 2 and 100. You take that number, 200 in this case, and divide it by 40 to get the variable by itself. This would leave you with what the variable equals, 5.
This is an equation that calculates potential energy and converts the value into its commercial unit.
<u>Step-by-step explanation:</u>
Step 1:
Given equation is 2 kg × 9.81 m/s² × 40 m. From the units, find the corresponding measurements. kg is the unit of mass (m), 9.81 m/s² is the acceleration due to gravity (g) and m is the unit of length or height (h).
This shows that this equation is to find potential energy. It is then converted into the commercial unit of energy (Joules).
⇒ Potential Energy = mgh = 2 kg × 9.81 m/s² × 40 m
= 784.8 kg m²/s²
= 784.8 N-m (Since unit of force, 1 N=kg m/s²)
= 784.8 J (1 Newton-m = 1 Joule)
Answer: Mean(Mia)=34.33 Mean(Sophia)=35.667
Sophia's phone calls on average, are longer in length than Mia's phone calls.
Step-by-step explanation:
Answer:
D. Undefined
Step-by-step explanation:
The slope is the ratio of rise to run. When the line is vertical, the run is zero, so calculating the slope involves division by zero. That makes the slope be <em>undefined</em>.
Answer:
Step-by-step explanation:
area πr²=28.26
r²=28.26/π
r=√(28.26/π)≈ 9cm
