Both questions make use of the formula for the area of a triangle:
.. A = (1/2)*b*h
23. A = (1/2)*b*h
.. A = (1/2)*x*7 . . . . substitute the given values
.. A = 3.5x . . . . . . . simplified
24. A = (1/2)*b*h
.. 84.5 = (1/2)*13*h . . . . . substitute the given values
.. 2*84.5/13 = h = 13 . . . .solve for h
The height of the triangle is 13 cm.
Answer:
Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean. Mean absolute deviation is a way to describe variation in a data set. Mean absolute deviation helps us get a sense of how "spread out" the values in a data set are.
Step-by-step explanation:
To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values. Find the absolute value of the difference between each data value and the mean: |data value – mean|.
Answer:
Step-by-step explanation:
Part A:
3x+12+7x+88=180
10x+100=180
10×=80
X=8
Part B:
m<RPS=3x+12
(3*8)+12
=36
Answer:
The answer is B.
Step-by-step explanation:
Simply you change 6 3/4 into decimal form which is 6.75 then you divide it by the amount which is 3/4= .75
divide 6.75 by .75 equals 9

Answer: 10 1/2, which can be simplified as 10.5
Explanation: First, set up a proportion with acres of corn to time in hours:
8 3/4 acres = x acres
5/6 hour = 1 hour
Reorder the terms:
x = (8 3/4) / (5/6)
To figure that out the math, change the mixed fraction to an improper fraction, and change the division into a multiplication:
x = (35/4) * (6/5)
Next cancel out:
x = (7/2) * (3/1)
x = 21/2
Lower that faction the the lowest denominator:
21/2 = 10½
Thus, your answer is 10½, or in other words 10.5
Hope this helps! :)
