Popcorn would be 7.98. Drinks would be 5.25. Togather they would be 13.23.
Answer: The input values are B-number of hours (x).
The output values are C-charge for babysitting(y).
The value of $10 represents the B-y intercept.
The value of $8 represents the C-slope.
Step-by-step explanation:
Charges to drive to the home= $10
Additional charges per hour=$8
Let x be the hour she worked (independent variable) and y be the total charge for baby sitting (dependent variable)
Thus, the input values are number of hours (x) and the output values are charge for babysitting(y)
According to the situation the equation would be
y=8x+10
which is equivalent to the slope intercept form y=mx+c, where
m=8, slope of line
At x=0, y=10
Thus, $10 represents the y intercept
Answer: m = 11
Step-by-step explanation: Isolate the variable by dividing each side by facotrs that don't contain the variable.
Hope this helps you out! ☺
Answer:
≈ 58
Step-by-step explanation:
Estimation usually means you want an answer good to one or maybe two significant figures. That usually means you want to round the numbers involved to one or two significant figures.
Doing that here transforms the problem to 180/3 = 60, an answer with one significant figure.
You can improve the estimate a bit by recognizing that it is a little high (the numerator is higher than 175.32, but the denominator is the same). Since the numerator is high by about 5, the estimate is high by about 5/3 or a little less than 2. A closer estimate will be 60 - 2 = 58.

The degree to which you refine the estimate will depend on the error requirements you have. Certainly an estimate of 60 is within 10% of the true value, so is "close enough" for many purposes.
