The baby sleeps from 9pm to 5am. How many hours does the baby sleep?
Answers
Answer: 8 hours.
Step-by-step explanation:
If the baby sleeps from 9pm to 5am, you will count. 9pm-12am is 3 hours of sleep. if you add 5 more hours, (12am+5 hours) it equals 5am. 5hours + 3hours is 8 hours.
Answer: 8 hours
Step-by-step explanation:
if you add 9+5 you will get 14 but if you count it like you would for hours it would be 9-10-11-12-1-2-3-4-5

Company B has an initial fee of $65 in charges an additional $0.90 for every mile driven.
For what mileages Will company a charge less than Company B
Answers
Answer:
The mileages for which company A charge less than company B when , y 50 .
Step-by-step explanation:
Given as :
The two truck companies have following prices
Company A
The initial fee = i = $110
And unlimited mileage
Company B
The initial fee = I = $65
Additional charge = $0.90 per mile driven
Let it driven x mile
Let The mileages for which company A charge less than company B = y
Now, According to question
Charges of company A = charges of company B
i.e i = I + 0.90 × x
Or, $110 = $65 + 0.90 × x
Or, $110 - $65 = 0.90 × x
Or, $45 = 0.90 × x
∴ x =
i.e x = 50
i.e Company B driven x = 50 miles
So, The mileages for which company A charge less than company B = y
And y x
i.e y 50
Hence, The mileages for which company A charge less than company B when , y 50 . Answer

you're doing something wrong and then walk away and leave you hanging,
without helping you do it right.
And there's another weird thing here: The equation you squeezed in there
in the blank line is EXACTLY CORRECT. That's exactly the answer to the
next line, where it ways "Define a variable and then write ... an equation ...".
You've already got that, and you're on your way.
In your equation, 'x' is the price of the second painting. When you solve your
equation, you'll know that, and you'll be able to find the price of the first one.
Then you'll immediately know which one was the most expensive.
The important thing is: You've already finished the toughest part ! The rest
is just some arithmetic. Great work !

To find the number of Hamburgers sold on Monday, set up an equation and solve for 'x'. 350 hamburgers were sold on Monday.
To find the number of hamburgers sold on Monday, let's assume the number of hamburgers is 'x'. Given that there were 61 fewer cheeseburgers sold, the number of cheeseburgers can be represented as 'x - 61'. The combined total of hamburgers and cheeseburgers sold is 639, so we can set up the equation: x + (x - 61) = 639.
Simplifying the equation, we have 2x - 61 = 639.
Adding 61 to both sides gives 2x = 700. Dividing both sides by 2, we find x = 350.
Therefore, 350 hamburgers were sold on Monday.

Final answer:
The equation to find the value of R depends on the context. For resistors in series, the equation is R = R₁ + R₂ + R₃ + ..., while for parallel it is 1/R = 1/R₁+1/R₂ + 1/R₃ +.... In power calculations, the equation R = V²/P can be used.
Explanation:
To find the value of R, we can use various mathematical formulas depending on the context. For instance, in the context of circuits, the total equivalent resistance (R) of resistors in series is given by the equation R = R₁ + R₂ + R₃ + .... While for resistors in parallel, the equation is 1/R = 1/R₁+1/R₂ + 1/R₃ +....
In terms of power, the equation P = V²/R can be rearranged to R = V²/P to find the value of R. In case of calculations involving thermal resistance, the equations can be more complex and might require the use of other variables.
