Answer:
38.13 ft squared
Step-by-step explanation:
Since it is half of a circle we first find the area of a normal circle then divide by two.
So to find the area of a circle it is pi times radius squared which in this case it would be 3.14 times 9 = 28.26
Then since it is a half circle we divide by two so
28.26/2 = 14.13
Then to find the area of the triangle we do 4 times 6 which is 24.
now we add the two which is 14.13 + 24 which is
38.13
Answer: 11
Step-by-step explanation:
Set up an equation
Based on the question, we can determine that 4x = 22 + 2x where x in is the number
"Four times a number" -> <u>4x</u>
"was" -> <u>=</u>
"22 greater than" -> <u>22 +</u>
"twice the same number" -> <u>2x</u>
Put the underlined parts together to get <u>4x = 22 + 2x</u>
Solve equation
Rearrange/collect like terms to solve for x by subtracting 2x from both sides
4x = 22 + 2x
2x = 22
Solve for x by dividing each side by 2
2x = 22
x = 11
Final Answer
x = 11
It should be noted that the relationship is not linear based on the information illustrated as the difference between the numbers aren't the same.
<h3>How to illustrate the information?</h3>
It should be noted that an equation is simply used to illustrate and express the relationship between the variables.
It should be noted that for the relationship to be linear, it's essential that they've the same relationship between them.
When x = 1, y = 4.5. The
When x = 2, y = 6.5
When x = 3, y = 8.5
When x = 4 y = 11.5
It should be noted that there's a difference of 2 at first but between 3 and 4, there is. a difference of 3.
Therefore, the relationship is not linear.
