Answer:
Cost of Material per square foot = $1.7
Step-by-step explanation:
Given:
Length = 24
Width = 12
Height = 6.5
Find:
Cost of Material per square foot
Computation:
TSA of pit = 2[bh + hl] + lb
TSA of pit = 2[(12)(6.5) + (24)(6.5)] + (24)(12)
TSA of pit = 2[78+156] + 288
TSA of pit = 756 square foot
Cost of Material per square foot = 1,285.20 / 756
Cost of Material per square foot = $1.7
Answer:
AB=29; BC=27
Step-by-step explanation:
So they told us AB=4x+9 and that BC=5x+2, and AC=56 , now to help with the question you can draw this information on a number line. Now on a number you can see that basically AC=AB+BC.
So you would write it as such,,
4x+9+5x+2=56
Combine like terms
9x+11=56
Now you have to isolate the x by itself but first get rid of the 11.
9x+11-11=56-11
You would get
9x=45
Here you can divide 9 by both sides to isolate x.
9x/9=45/9
{x=5}
Now to find the value for both substitue x in the equations for both
1. AB=4x+9 where x is 5
4(5)+9 =AB
20+9 =AB
29=AB
You would do the same with BC
2. BC= 5x+2 where x is 5
5(5)+2= BC
25+2= BC
27=BC
If you want to check your answers you can just substitute x for 5 in the first equation we did where AC=AB+BC
The points on the graph of the inverse variation are of the form:
(x, 8/x)
<h3>
Which ordered pairs are on the graph of the function?</h3>
An inverse variation function is written as:
y = k/x.
Here we know that k = 8.
y = 8/x
Then the points (x, y) on the graph of the function are of the form:
(x, 8/x).
So evaluating in different values of x, we can get different points on the graph:
- if x = 1, the point is (1, 8)
- if x = 2, the point is (2, 4)
- if x = 3, the point is (3, 8/3)
- if x = 4, the point is (4, 2)
And so on.

Answer:
2.99
Step-by-step explanation:
<em>Note: [log10 = 1]</em>
<em> [log8 = 0.903089987]</em>
2log10 = 0.3010
<em> </em>22log8 = x
Therefore:
<em>2log10 x = 22log8</em>
<em>x = 2.99</em>
