Answer:
w= -9/8
Step-by-step explanation:
-1/3w -3/5 = 1/5w
+1/3w +1/3 w
-3/5=1/5w+1/3w
Make common denominators to combine like terms of the right
-3/5=1/5w+1/3w
*3 *5
-3/5=3/15w+5/15w
-3/5=8/15w
multiply both sides by the reciprocal of 8/15 which is 15/8
-3/5*15/8=8/15w*15/8
* ----> cross reduce 5 in the denominator becomes 1 and 15 in the numerator becomes 3
* -----> now multiply across
w= -9/8
You divide 30 1/3 ÷ 6 1/2 = 4 2/3 after that you need to multiply 6 1/2 and 4 2/3 to see if that gives you the area of 30 1/3 and it those so your answer is 4 2/3
The slopes of two perpendicular lines are negative reciprocals of each other. The slope of the line perpendicular to the one in this question is -3.
Answer:
See Explanation
Step-by-step explanation:
<em>The question is incomplete, as the required data to answer the question are missing.</em>
<em>However, the interpretation of the question is to determine the interquartile range (IQR) of a certain dataset.</em>
<em>Then get the difference between the calculated IQR & Joe's data and also the difference between the calculated IQR & Sam's data</em>
<em>Then, make comparison</em>
<em />
To do this, I will use the following assumed datasets.
IQR is calculated as:
is of the upper half
is of the lower half
For Joe, we have:
The median is then calculated as:
For, the lower half:
So:
For the upper half:
So:
When the same process is applied to Sam's data,
Assume that:
<em>Hence, the IQR is 47 points less for Joe's data than Sam's</em>
Do 180-110 to find the right corner angle of the triangle. then add 40 and subtract that from 180 to get x. then divide 110 in half to find y. you should get x=70 and y=55
