Answer:
height = 5 in
Step-by-step explanation:
Area =h x (b1+ b2)/2
50 = h x (12 + 8)/2
50 = h x 10
h = 5
U multiply 5times 6 equals 30
Answer:
A=920 ft.
Step-by-step explanation:
Using the formulas
A=2AB+(a+b+c)h
AB=s(s﹣a)(s﹣b)(s﹣c)
s=a+b+c
2
Solving for A
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=8·20+17·20+15·20+1
2·﹣84+2·(8·17)2+2·(8·15)2﹣174+2·(17·15)2﹣154=920
Answer:
percents to decimals
a) .02 b) .79 c) 1.35
Step-by-step explanation:
for converting percents to decimals you always move the decimal over to the left 2 times
Inequalities are used to show the relationship between unequal expressions
- <em>The set notation of (5) and (6) are: </em>
<em> and </em>
<em>.</em> - <em>See attachmen</em>t for the graphs
The following should be notated when plotting the graph of an inequality
- < and > are represented with open circles, while
and 
are represented with closed circles - The arrows of
and 
point to the left, while the arrows of 
and point to the right.
So, we have:
Rewrite as:
The graph of will point to the right, and it will use an open circle
Split the inequality:
and 
<em>It is not possible for -6 to be less than x and at the same time, x is greater than or equal to -2.</em>
<em />
Hence. 
cannot be represented on a graph
Split the inequality:
and 
means that -4 is less than x or x is greater than -4.
So, we have:
and
If and , then we make use of because it contains more values of x.
The graph of will point to the right, and it will use an open circle
