Answer:
61-27=34
Step-by-step explanation:
start with the ones place:
1-?=4
since 1 minus anything will never give a 4 add 10
11-?=4
11-4=?=7
then start with the tens place:
?1-27=34
?1=34+27
?1=61
Step-by-step explanation:
Relations can be written as ordered pairs of numbers or as numbers in a table of values. By examining the inputs (x-coordinates) and outputs (y-coordinates), you can determine whether or not the relationship is a function. Remember, in a function, each input has only one output.
A function is a relationship where there is only one output for every input. In other words, for every value of x, there is only one value for y. A functioning rule describes how to convert an input value (x) into an output value (y) for a given function. An example of a function rule is f(x) = x^2 + 3.
The phrase "y is a function of x" means that the value of y depends upon the value of x, so: y can be written in terms of x (e.g. y = 3x ). If f(x) = 3x, and y is a function of x (i.e. y = f(x) ), then the value of y when x is 4 is f(4), which is found by replacing x"s by 4"s .
The bicycle`s speedometer measures the speed to the nearest 0.1 mph. So 17.15 mph is not appropriate way to report speed, because then it should measure speed to the nearest 0.05 mph. Also 17 mph and 20 mph are whole numbers and it does not have to be so accurate.
Answer: B. 17.1 mph
The time it takes for the car to complete one revolution around the track is calculated by dividing the circumference of the circular track by the speed of the car.
This may mathematically be expressed as,
time = circumference / speed
