Answer:
all work is shown and pictured
To answer this, we need to know the formula of the relationship between the work and the power rating and time.
The formula is:
E(J)<span> = </span>P(W) ×<span> t</span><span>(s)
</span>360000 = 200 * t
t = 360000 / 200
t = 1800 s
So, Emily will spend 1800 seconds in vacuuming. It is also equivalent to 30 minutes.
The independent variable is the type of material the balls are made from
Answer:
11.11 hours
Step-by-step explanation:
Rita = 20 hours
Neha = 25 hours
Let the time that they can complete the work together be written as x
1/20 + 1/25 = 1/x
Lowest Common Denominator is 500
25 + 20/500 = 1/x
45/500 = 1/x
Cross Multiply
45x = 500
x = 500/45
x = 11.111111111 hours
Approximately = 11.11 hours
Therefore, it would take Rita and Neha 11.11 hours to complete the work together.
Answer:
2 <= x < 8
Step-by-step explanation:
2 is less than or equal to x and the symbol for that is <=
the least number should also be on the left side
8 is greater than x so the symbol is <
8 is the biggest number and goes on the right
