Hi There!
Given:
- A placemat requires 30 feet of ribbon
- Mandy has 200 feet of ribbon
To Find:
How many placemats can Mandy make, if she has 200 ft of ribbon?
Solve:
200÷30≈7
Thus, she can make 7 placemats.
<h3>Hope it helps & enjoy your day!</h3>
Answer:78% countries
Step-by-step explanation:
Maybe because you're finding the "difference" between the two numbers. We could also question why the answer to an addition problem is called sum.
Well, 'sum'body said that's what they should be called a long time ago, that's why we're using that term to call them now.
The table and the plotted data are in the attachment.
Answer and Step-by-step explanation: A line of best fit is the best approximation of the given data. It is used to show the relation of two variables and it can be determined, more accurately, by the Least Square Method.
To use the method, follow the steps:
1) Calculate the mean of the two variables:
2) The Slope of the line is given by:
3) The y-intercept is found by the formula:
For the ripening of bananas, the least square method gives the line:
y = -0.142x + 5.56
The rate of change of a line equation is its slope, so
Rate of change = -0.14
The rate of change of ripening time with respect to exposure time is -0.14, which means the more expose the fruit is, the less time it needs to ripe.
