A wire of length 22cm is bent in the shape of a circle . find the area of the circle. if the same wire is recent in the form of a square, find it's area which figure encloses more area
The circle is found to have the more area as compered to the square.
What is termed as the perimeter?A perimeter is a loop that encompasses, encircles, or outlines a two-dimensional shape or length. The circumference of a circle or perhaps an ellipse is its perimeter.For the given question;
The length of the wire is given as 22 cm.
The wire is bent in the circle.
Then, the perimeter of the circle is 22 cm.
Perimeter = 2πr = 22 cm.
Where, π = 3.14 and r is the radius of the circle.
2πr = 22 cm.
r = 11/π 11/3.14
The area of the circle is found as;
Area = πr²
Put the values.
Area = 3.14(11/3.14)²
Area = 38.53 cm².
For the square.
Perimeter = 4 side
22 = 4 side
side = 22/4 = 11/2 = 5.5
Area of square = side²
Area of square = 5.5²
Area of square = 30.25 cm².
Thus, the circle is found to have the more area as compered to the square.

Miguel bought snacks for his team's practice. He bought a bag of popcorn for $3.33 and a 20-pack of juice bottles. The total cost before tax was $23.33. How much was each bottle of juice?
The cost of each bottle is $[tex]1[/tex]
Given:
A bag of popcorn costs $[tex]3.33[/tex]Miguel bought [tex]20[/tex]packs of juice bottlesThe total cost before tax was $[tex]23.33[/tex]To find: Cost of each bottle of juice?
It is given that Miguel bought snacks for his team's practice which includes a bag of popcorn, and [tex]20[/tex] packs of juice bottles out of which the bag of popcorn cost him $[tex]3.33[/tex] , and the total cost before tax of all the items costs him $[tex]23.33[/tex]
Now we have to find that how much each bottle of juice costs him as asked in the given question.
Let the bag of popcorn's amount be x and the pack of bottle juice is y
Now according to the linear equation in two variable
[tex]x*1+y*20=23.33[/tex]........(1)
where 1 is the total pack of popcorn bag and [tex]20[/tex] the amount of bottle juice packs
As we know that [tex]x=3.33[/tex] since a bag of popcorn costs him $[tex]3.33[/tex]
Now put the value of x in (1) hence,
[tex]3.33*1+y*20=23.33[/tex]
On further solving we get,
[tex]20y=20[/tex]
On further solving we get,
[tex]y=1[/tex] as the price of every juice of bottle.
Hence a bottle of juice costs him $[tex]1[/tex]

Write a system of equations to describe the situation below, solve using any method, and fill in the blanks. Students in Mrs. McGee's third grade class are working on times tables, and they demonstrate mastery by passing tests. Rebecca has passed 12 tests so far. Her classmate, Marie, has passed 3 tests of them. From now on, Rebecca plans to take and pass 2 tests per week. Meanwhile, Marie plans to do 5 per week. At some point, Rebecca will catch up to Marie. How long will it take? How many tests will each child have passed? In weeks, the children will each have passed tests.
Solution
Given the question in the image, the following are the solution steps to answer the question.
STEP 1: Represent the unknown terms
Let x represents the number of weeks
Let y represents the total number of test passed
STEP 2: Interpret the statements
For Rebecca

Answer:
Explanation:
The volume of a cylinder is given by
[tex]V=\pi r^2h[/tex]Now, to correct the order of the cylinders from least to greatest, we have to calculate the volume of each.
(a). A cylinder with a diameter of 28 units and a height of 18 units.
Diameter is 2 times radius; therefore, r = 14 and the volume is
[tex]V=\pi(14)^2\times18[/tex][tex]V=3529\pi[/tex](b). A cylinder with a radius of 13 units and a height of 17 units.
The volume is
[tex]V=\pi(13)^2\cdot17[/tex][tex]V=2873\pi[/tex](c). A cylinder with a diameter of 30 units and a height of 14 units.
The radius is 15 units; therefore, the volume is
[tex]V=\pi(15)^2\cdot14[/tex][tex]V=3150\pi[/tex](d). A cylinder with a radius of 12 units and a height of 20 units.
The volume is
[tex]V=\pi(12)^2\cdot20[/tex][tex]V=2880\pi[/tex]Hence, from least volume to greatest volume the order is

What is the Function :A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.
In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.
So,
We can write,
One input value has more than output values.
In this function we have,
-1 is mapped to both -2 and -1
In this case,
-1 input value is mapped to both output values of -2 and -1.
Therefore,
No, because there is an input values with more than one output value is the following relation a function.

Rashids original weight based on the information illustrated is 225lb.
What was the original weight?From the information given, after the nutrition program rashid has lost 16% of his original weight he lost 36lb.
Let the original weight be given as x.
Therefore, 16% × x = 36
0.16x = 36
Divide through by 0.16
0.16x / 0.16 = 36 / 16
