Answer:
390 ft^2
Step-by-step explanation:
We will break this shape into two rectangles, one that is 7 ft wide by 30 ft long
and the other that is 25ft-7ft wide by 30ft -20 ft long (18 ft by 10 ft)
1st: 7 ft by 30 ft
A = l*w = 7*30 = 210 ft^2
2nd: 18 ft by 10 ft
A = l*w = 18 * 10 = 180 ft^2
Add the areas together
210+180 = 390 ft^2
Answer:

Step-by-step explanation:
Let
x ----> the length of the third side of triangle in Lauren's sculpture
we know that
The <u><em>Triangle Inequality Theorem</em></u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
Applying the Triangle inequality Theorem
1) 

Rewrite

2) 

therefore
The possible values of x are

Answer:
The answer is D, 43 
Step-by-step explanation:
If the pile gets bigger by 8
each week, and you want to find out how big the pile is after 3 weeks, then you have to multiply 8
by 3 to find out how much the pile increased by.
8
× 3 = 25 
Now, you need to add this to your initial value to get the answer.
25
+ 17
= 42 
Now simplify.
43 
9 times 36 equals 364 there's ur answer and ur welcome
Answer:
The value of the test statistic is 
Step-by-step explanation:
The null hypothesis is:

The alternate hypotesis is:

Our test statistic is:

In which X is the sample mean,
is the null hypothesis value,
is the standard deviation and n is the size of the sample.
In this problem:

So



The value of the test statistic is
