11/8 or 1 3/8
You must have the same denominator. Therefore, multiply 1/2 by 4 to get a denominator of 8. Be sure to do this for the numerator as well. You end up with 4/8 plus 7/8. You result with 11/8 or simplified 1 3/8.
Answer:
8
Step-by-step explanation:
The median is the middle of the numbers in a given data set.
To find the median, line up all of the numbers from greatest to least.
4, 6, 7, 9, 9, 10
Now, find the middle of the numbers. Since there is an even number of numbers in the data set, find the two middle numbers.
4, 6, 7, 9, 9, 10
Next, find the average of these two numbers. (To do this, add the numbers and divide that sum by 2.)
7 + 9 = 16
16/2 = 8
Therefore, the median is 8.
S= 70w + 750
s(19) = 70w x 19+350= 1680
so its 1680
If Dinah can skate 1/2 lap in 15 seconds,she can skate 1 lap in 30 seconds. This is because 15 multiplied by 2 is equal to 30.
