The length and width of a rectangular field fully enclosed with 218 metes fencing are 63 meters and 46 meters respectively.
The perimeter of a rectangle is the sum of the whole four sides. Therefore, the perimeter of a rectangle is defined as follows:
where
l = length
w = width
perimeter = 218 meters
The length of the field is 17 meters longer than the width, w. Therefore, the length is defined as follows:
The length and the width can be calculated as follows:
218 = 2(l + w)
218 = 2(17 + w + w)
218 = 34 + 4w
218 - 34 = 4w
184 = 4w
divide both sides by 4
w = 184 / 4
w = 46 meters
length = 17 + 46
length = 63 meters

The average rate of change in the median household income over this time period is $745.5
<h3>What is the average rate of change in the median household income over this time period?</h3>
The given parameters are:
2000, the median household income was $41,990.
2010, it was $49,445.
The average rate of change in the median household income over this time period is calculated as:
Average rate of change = (Difference in Income)/(Difference in years)
So, we have:
Average rate of change = (41990 - 49445)/(2000-2010)
Evaluate
Average rate of change = 745.5
Hence, the average rate of change in the median household income over this time period is $745.5

Answer: x = 15; y = 32; z = 2.5
see in the picture, u can see that this parallelogram has a right angle and two adjacent equal edges.
=> this parallelogram is a square
=> the diagonal lines of the parallelogram are perpendicular to each other
=> m∠1 = 90°
⇔ 3y - 6 = 90
⇔ 3y = 96
⇔ y = 32
because this is a square
=> 3x = 18z = 45°
=> x = 15
z = 2.5
Step-by-step explanation:
Answer:
<u>B. spin a spinner with 4 equal sections two times.</u>
Step-by-step explanation:
There are 4 boys and 2 girls in the Science Club.
2 members will give the demonstration at the science fair.
And at least one of the demonstrators will be a girl.
So, it is convenient to choose a simulation method with 4 outcomes.
The suitable simulation is spin a spinner with 4 equal sections two times.
The first time of the spinner we will choose a boy, each section from the four section will represent one boy.
The second time, we will choose a girl, each 2 section from the four sections will represent one girl.
<u>The answer is option B. spin a spinner with 4 equal sections two times.</u>
