Answer:
We know that the rectangular plate has measures of:
length = 7.6 ± 0.05 cm
width = 3.1 ± 0.05 cm
(the error is 0.05cm because we know that both measures are correct to one decimal place)
First, the upper bound of the length is equal to the measure of the length plus the error, this is:
L = 7.6 cm + 0.05 cm = 7.65 cm
The upper bound of the area is the area calculated when we use the upper bound of the length and the upper bound of the widht.
Remember that the area for a rectangle of length L and width W, is:
A = W*L
Then the upper bound of the area is:
A = (7.6cm + 0.05cm)*(3.1cm + 0.05cm) = 10.8 cm^2
Answer:I would name it jimmy
Step-by-step explanation:
He is waiting in letter P
we have

The solution is the shaded area above the dotted line
we know that
If a point is a solution of the inequality, then the coordinates of the point must satisfy the inequality
We will verify all cases to determine the solution of the problem
<u>Case A)</u> Point 

Substitute the value of x and y in the inequality and verify

-------> is not true
therefore
the point
is not a solution of the inequality
<u>Case B)</u> Point 

Substitute the value of x and y in the inequality and verify

-------> is true
therefore
the point
is a solution of the inequality
<u>Case C)</u> Point 

Substitute the value of x and y in the inequality and verify

-------> is not true
therefore
the point
is not a solution of the inequality
<u>Case D)</u> Point 

Substitute the value of x and y in the inequality and verify

-------> is not true
therefore
the point
is not a solution of the inequality
therefore
<u>the answer is the Point B</u>
