Answer: The tenth term is 76
=======================================================
Explanation:
We use this arithmetic sequence formula to get the nth term
Plug in 
and you should get the following:
The tenth term is <u>76</u>
---------
We can verify this by listing out the terms one by one. Start at 4, add on 8 each time, until you generate the 10th term. A table like the one shown below is a good way to keep track of all the terms.
---------
In short, the error is with the "10" in the expression 4+10(8). The student should have used 9 instead. This is because of the n-1 term in which shifts everything one spot to the left.
Answer:
the answer would be 217 [degrees]
Step-by-step explanation:
Since m<1 and m<2 are next to each other, they are adjacent. Adjacent angles must share a common side which is m<W. This means they have to be added. m<1+m<2= m<XYZ
145+72=217
The answer to this question is:
280ft^2 for surface area
The volume is 300ft^2
Answer:
The area of the garden is 
Step-by-step explanation:
<u>Area of a Square</u>
Given a square of a side length of x, the area is calculated as:
There is a square garden area of a side length of x=50 feet. The area is:
Inside of it, there is another square area for a fountain display of a side length of 12 feet. The area is:
The area of the garden is the difference between A2 and A1:
9514 1404 393
Answer:
x° ≈ 50.0°
Step-by-step explanation:
The sides adjacent and opposite the angle are given. The appropriate trig relation is ...
Tan = Opposite/Adjacent
tan(x°) = 50/42
The inverse function is used to find the angle whose tangent is a particular value:
x° = arctan(50/42) ≈ 49.9697°
x° ≈ 50.0°
