A circle has its center at the center of a square with 10 inch sides. Find the area of the square not covered by the circle to the nearest 10th
Assuming that the diameter of the circle is the square's side, then we have
Area of square: S1=10×10=100in²
Radius of circle: r=10/2=5in
Area of circle: S2=pi×r²=3.14×5²=78.54in²
Remaining area: S1-S2=100-78.54=21.46in².
Rounding to the nearest tenth: 21.5in².
Answer: 21.5in²
The area of the square not covered by the circle is calculated by first determining the areas of the square and the circle, and then subtracting the latter from the former. The area of the square is 100 square inches and the area of the circle is approximately 78.5 square inches. Subtracting these gives approximately 21.5 square inches.
Explanation:First, let's find the area of the square. Since all sides are equal in a square, the area can be found using the formula side ⨉ side. In our case, the sides of the square are 10 inches, so the area is 10 inches ⨉ 10 inches = 100 square inches.
Next, we'll need to find the area of the circle. The radius of the circle is equal to half the length of a side of the square, or 5 inches. Use the formula for area of a circle, which is πr². So the area of the circle is π(5 inches)² = 25π square inches ≈ 78.5 square inches.
To find the area of the square not covered by the circle, simply subtract the area of the circle from the area of the square. 100 square inches - 78.5 square inches = 21.5 square inches, thus this is the area of the square not covered by the circle.

You have a field 250 feet wide and 325 feet long planted in strawberries. How many acres of strawberries are in this field?
Answer: 81,250
Step-by-step explanation: find the area. Multiply the length x width. I got 81,250 by multiplying these numbers.
A field that is 250 feet wide and 325 feet long, can be calculated as 81,250 square feet. Since one acre equals 43,560 square feet, this field's size is approximately 1.87 acres.
Explanation:The question is about converting a field measure in feet into acres. Given that the field is 250 feet wide and 325 feet long, the total area in feet is found by multiplying these two dimensions. Thus, the total area is 250 * 325 = 81,250 square feet.
Now, to convert this into acres, we should know that 1 acre is equal to 43,560 square feet. So, to calculate how many acres is 81,250 square feet, we divide 81,250 by 43,560.
This gives 1.87 acres (rounded to two decimal places). So, this field's size, planted with strawberries, is approximately 1.87 acres.

The sum of two numbers is 11 and their product is 18. Find the numbers.
Answer: the numbers are 9 and 2
Step-by-step explanation:
Let the numbers be a and b
a + b = 11.........equation 1
ab = 18.......equation 2
Multiply equation 1 by a
a ^2 + ab = 11a.......equation 3
Substitute the value of ab from equation 2 into equation 3
a ^2 + 18 = 11a
a^2 - 11a + 18 = 0
(a-9) x (a-2) = 0
If a = 9, then b =2

Step-by-step explanation:
Sorry man
Final answer:
The circumference of a circle with a diameter of 40 inches using 3.14 for pi is 125.6 inches, rounded to the nearest tenth.
Explanation:
The student's question is asking for the circumference of a circle with a given diameter using 3.14 for π (Pi). According to the relationship between the diameter and the circumference of a circle, the circumference (C) can be found by multiplying the diameter (d) by π. The formula for the circumference is thus C = πd.
In this case, the diameter is given as 40 inches. Therefore, we calculate the circumference as follows:
C = πdC = 3.14 × 40 inC = 125.6 inSince we are asked to round to the nearest tenth, the circumference of the circle is 125.6 inches.

Solution:
Given data:
[tex]$\cos -- = \frac{7}{14}[/tex]
Let the unknown degree be x.
To find the degree x:

Answer:
Surface Area
Step-by-step explanation:
Its's basically the total area of all faces in the three-dimensional figure.
Final answer:
The total area of all the faces of a three-dimensional figure is known as the surface area. It can be calculated differently based on the shape, like multiplying one face's area by six for a cube or summing up the areas of each face for a more complex shape.
Explanation:
The total area of all the faces of a three-dimensional figure is called the surface area. There are various methods to calculate the surface area depending on the shape of the three-dimensional object. For example, a cube has six faces, and the surface area can be found by calculating the area of one face and then multiplying by six. For more complex shapes, one might need to calculate the area of each face separately and sum them up.
For instance, taking a cube, if each face has an area of 4 square inches, then the total surface area of the cube would be 4 square inches multiplied by 6 faces, resulting in 24 square inches. If we then divide this cube into smaller cubes, the surface area-to-volume ratio of these smaller cubes would increase. When dealing with areas or volumes of objects with complex shapes, often, they're idealized to reflect simpler shapes like a cube or a sphere.

Mike has $25.00 to rent paddleboards for himself and a friend for 3 hours. Each paddleboard rental costs $3.75 per hour. Use the drop-down menus to complete the statements below about the paddleboard rentals.
Solution:
Given that,
Mike has $25.00 to rent paddleboards for himself and a friend for 3 hours
Each paddleboard rental costs $3.75 per hour
So there are two persons = mike and his friend
1 hour = $ 3.75
Therefore, for 3 hours:
[tex]3 \times 3.75 = 11.25[/tex]
Thus for two person:
11.25 + 11.25 = 22.5
Thus it costs $ 22.5 for mike and his friend to rent paddle board for 3 hours
Remaining amount = 25 - 22.5 = 2.5
Thus Mike has $ 2.5 remaining after rental

Answer:
13 and -14 satisfy this condition
Step-by-step explanation:
Let's represent that number as x
and the square of x is x^2
So,
x + x^2 = 182
Subtract 182 from both sides
x + x^2 - 182 = 182 - 182
x + x^2 - 182 = 0
rearrange the quadratic equation
x^2 + x -182 = 0
let's use the quadratic formula

a = 1, b = 1, c = -182

10
20
50
529
Answer:
Required margin of error = 20
Step-by-step explanation:
Required margin of error = 20
so , option (2) is the correct answer.
Explanation:
Values are given as,
we will have to need confidence level to calculate margin of error so ,we assume 95% confidence level .
z = 1.96 (critical value of 95%)
sample size n = 25
standard deviation = 50
Using the formula
Margin of error E = z∗(σ/ n )
putting the values
1.96∗(50/ 25)
= 19.6
=20
Required margin of error : E = 20
Answer: Jo's margin of error is M = 20
Step-by-step explanation:
The margin of error can be calculated as:
M = z*σ/√n
where:
z depends on the confidence interval with we are working, let's use 95%, so z = 1.96
σ = standard deviation = 50
n = number of the sample.
So for Jo we have:
M = 1.96*50/√25 = 1.96*50/5 = 1.96*10 = 19.6
So if we round it to the nearest whole number, we should round up, and we get:
M = 20
