4.5mm divided by 0.5mm is equal to 9
then you multiply 4 by 9 which gives 36 cm which is the actual height of the object.
Answer:
B. Function.
Step-by-step explanation:
We have been given a set. We are asked to choose the correct option about the given set.
We know that a set represents a relation, when each x value corresponds to a y-value. In a relation one x-coordinate can have more than one y-values.
We know that a set represents a function, where each x-value corresponds to exactly one y-value.
Two different value can have same y-value to be a function.
We can see that each value of x corresponds to exactly one y-value. The value of y is 2 for all value of x, therefore, all points lie on a horizontal line
.
Therefore, our given set a function.
Answer:
80% of the students passed the algebra test
Step-by-step explanation:
So for this question, they want to know the percentage of the people that passed.
20 out of 25 students passed, we could find the percentage using two ways:
-------
1. We can use proportions to figure out the percentage (This can only work if the numbers are factorable by 100 such as 10, 25, 50...)
25 × 4 would equal 100. You must multiply the same number to the top as well.
So 20 × 4 = 80
--------
2. We can divide the two numbers
20 ÷ 25 = 0.8
When changed into a percentage, 0.8 would be 80%
-------
Have a good day :)
