Step-by-step explanation:
Answer:
x=11.2
Step-by-step explanation:
cross multiple 100 over x equals 200 over 22.4
100(22.4) = 200x
2,240 = 200x
divide
11.2=x

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answers
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.
C = 2πr
where C is the circumference and r is the radius of the circle.
In this case, we are given that the circumference is approximately 18 feet, so we can set up the following equation:
18 = 2πr
Solving for r, we get:
r = 9/π ≈ 2.864 feet
Now we can use the formula for the area of a circle:
A = πr^2
Substituting the value we found for r, we get:
A = π(2.864 ft)^2 ≈ 25.85 ft^2
Therefore, the approximate area inside the circular park is approximately 25.85 square feet.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

I am creating a garden that is rectangular. If the following ordered pairs are
the corners, what is the perimeter of my garden?
(-7, 10), (-7, 2), (4, 10), (4, 2)
Answers
Answer: the perimeter of the garden is 38 units.
Step-by-step explanation:To find the perimeter of the garden, we need to add up the lengths of all four sides.
Starting with the bottom side, we can use the coordinates (-7, 2) and (4, 2). The distance formula tells us that the distance between these two points is:
d = √[(4 - (-7))^2 + (2 - 2)^2]
= √[11^2 + 0^2]
= √121
= 11
So the bottom side has a length of 11.
Moving to the right side, we can use the coordinates (4, 2) and (4, 10). Again using the distance formula, we get:
d = √[(4 - 4)^2 + (10 - 2)^2]
= √8^2
= 8
So the right side has a length of 8.
For the top side, we can use the coordinates (4, 10) and (-7, 10):
d = √[(-7 - 4)^2 + (10 - 10)^2]
= √11^2
= 11
So the top side also has a length of 11.
Finally, for the left side, we can use the coordinates (-7, 10) and (-7, 2):
d = √[(-7 - (-7))^2 + (2 - 10)^2]
= √8^2
= 8
So the left side has a length of 8.
Adding all four side lengths together, we get:
Perimeter = 11 + 8 + 11 + 8
= 38
To find the perimeter of the garden, we need to add up the lengths of all four sides.
Starting with the bottom side, we can use the coordinates (-7, 2) and (4, 2).

Club members wrote a program together, with several people working on each of 4 parts. If the first part of the program required 1/3 of the total time, the second part needed 1/2 of the remaining time, the third part took 30 minutes, and the fourth part took 60 minutes, how many hours did the program take to write?
Answers
Answer:
Step-by-step explanation:
4 parts: 1/3 + 1/2 + 30min + 60min
1/3 of an hour is = 20 minutes
1/2 of an hour is 30 minutes
20 + 30 + 30 + 60(1h)= 140 minutes = 2 hours and 20 minutes
The total time did the program take to write is 2 hours and 20 minutes.
It is required to find total time.
What is arithmetic?The branch of mathematics dealing with the properties and manipulation of numbers. a science that deals with the addition, subtraction, multiplication, and division of numbers. Fractions, decimals, percentages, fractions, square root, exponents, and other arithmetic operations are used to achieve mathematical simplifications.
Given that:
several people working on each of 4 parts.
First part = 1/3 of the total time,
The second part = 1/2 of the remaining time,
The third part =30 minutes,
Fourth part= 60 minutes,
So, the total time in hour.
4 parts:
1/3 of an hour is = 20 minutes
1/2 of an hour is 30 minutes
Total time=1/3 + 1/2 + 30min + 60min
=20 + 30 + 30 + 60(1h)
= 140 minutes
= 2 hours and 20 minutes.
So, the total time did the program take to write is 2 hours and 20 minutes.

The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?
Answers
Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.
58 + 85 = 143

No, the constant of proportionality is 2.
Yes, the constant of proportionality is 2.
No, there is no constant of proportionality.
Yes, there is no constant of proportionality.
Answers
Step-by-step explanation:
To find the slope
m = ∆y/∆x
m = (6 -0)/(2-1)
m = 6/1= 6
hence the slope is 6
now the other question
y = m(x -x1) +y1
y = 6(x - 1) +0
y = 6x -6
none of the options are right.
Answer:
Step-by-step explanation:
To find the slope of the linear relationship, we need to use the formula:
slope = (change in y) / (change in x)
We can choose any two points from the table to find the change in y and change in x. Let's choose the points (A1 ,B1)=(-1, -12) and (A2,B2)= (1, 0):
change in y =(B2-B1)= 0 - (-12) = 12
change in x =(A2-A1)= 1 - (-1) = 2
slope = change in y / change in x = 12 / 2 = 6
Therefore, the slope of the relationship is 6.
To determine if the linear relationship is also proportional, we need to check if the ratio of y to x is constant for all pairs of x and y in the table. calculate the ratios for each pair of x and y:
-2: -18/-2 = 9
-1: -12/-1 = 12
0: -6/0 (undefined)
1: 0/1 = 0
2: 6/2 = 3
We can see that the ratios are not constant, so the linear relationship is not proportion
