The circumference of a circle is 10 inches. What is its area in square inches?
Answer:
7.96 square inches.
Step-by-step explanation:
Area of a circle given a circumference is given by formula:
[tex]A = \frac{C^{2}}{4\pi}[/tex]
So substituting into equation we have: [tex]C= 10[/tex].
Therefore [tex]A = 10^{2}/4\pi = 100/4\pi=25/\pi =7.96[/tex] square inches.
The area of the circle is 7.96 square inches if the circumference of a circle is 10 inches.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
It is given that:
The circumference of a circle is 10 inches.
As we know the circumference of a circle is given by:
C = 2πr
C is the circumference of the circle.
r is the radius of the circle.
10 = 2πr
r = 5/π inches
As we know,
The area of the circle is given by:
A = πr²
Here, A represents the area of the circle.
Plug the value of the radius r in the above formula:
A = π(5/π)²
A = 25/π square inches
Take π = 3.14
A = 25/3.14
A = 7.96 sqaure inches
Thus, the area of the circle is 7.96 square inches if the circumference of a circle is 10 inches.

What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
An equation is a mathematical statement that shows that two mathematical expressions are equal.
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
An equation says that two things are equal.
For example, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.
Given that, Bill bought 5 apples Mary bought 2 apples and spent 1.86 for strawberries. both the spent equal amounts, we need to write and solve the equation for the price of apples,
Let the cost of 1 apple = A
Bill bought = 5A apples
Mary bought=2A + 1.86
5A = 2A + 1.86
3A = 1.86
A = 1.86/3
A = 0.62 cents
Hence, the cost of an apple was 0.62 cents.

Answer:
k = 3
Step-by-step explanation:
8k - (6k - 4) = 10
8k - 6k + 4 = 10
2k + 4 = 10
2k = 10 - 4
2k = 6
k = 3
Answer:
k=3
Step-by-step explanation:
8k-(6k-4)=10
Multiply everything inside of the parentheses by the negative.
8k -6k -4=10
Combine like terms
2k - 4 = 10
Subtract 4 from both sides
2k = 6
Divide by 2 on both sides

What Is the value of X?
Lines cut by a transversal line...
(2x–5)° + 45° = 180° (sum of consecutive interior angles
=> 2x + 40 = 180
=> 2x = 180– 40
=> x = 140 /2
=> x = 70
The required value of the x is 70 in the measures of the angle.
Given that Line m and n are parallel lines and intersect by a transversal line l.
When a transversal line intersects two other lines, it creates eight angles, four of which are called exterior angles and four are called interior angles.
From the sum of consecutive interior angles we have;
(2x–5)° + 45° = 180°
2x + 40 = 180
2x = 180– 40
x = 140 /2
x = 70

Answer:
Angle A = 65 degrees, Angle B = 78 degrees
Step-by-step explanation:
Since a triangle always has its vertices add up to 180 degrees to be a triangle, we can setup an equation on how to solve it. Adding all the vertices together into a formula to equal 180 degrees gives you 5x-5 = 180. Solving this equation will grant you an answer of x = 37 degrees, and taking this value and plugging it in for each requested angle is how to find the exact degree value. Angle A will just be 2(37) - 9, which ends up to be 65 degrees. Angle B is just 2(37) + 4, which becomes 78 degrees. (You can check the answer by taking all values and adding them together to equal 180. 78 + 65 + 37 = 180.) Hope that helps!
Answer: ∠A = 65° ∠B = 78°
The sum of all interior angles = 180°. So, set 180 equal to the angles you were given (in this case, 2x-9, 2x+4, and x), and solve for x.
180 = (2x-9) + (2x+4) + x (combine the like terms)
180 = 5x - 5 (isolate 5x by moving -5 to the other side)
5x = 180 + 5
5x = 185 (divide both sides by 5 to isolate for x)
x = 37°
Then, sub in the value of x (in this case, 37°) into ∠A and ∠B.
∠A = (2x-9) = 2(37)-9 = 65°
∠B = (2x+4) = 2(37)+4 = 78°
∴ ∠A = 65° and ∠B = 78°.

are 2x +4 = 10 and 3x +6 = 15 equivalent. equations? how do you know.
Answer:
Yes, the two equations are equivalent.
Step-by-step explanation:
For the first equation, we will solve for x.
2x + 4 = 10
Subtract 4 from both sides...
2x + 4 = 10
-4 -4
It then becomes
2x = 6
Then we divide by 2 on both sides.
2x = 6
2 2
Then the answer is...
x = 3
Now let's also solve for x on the second equation.
3x + 6 = 15
Subtract 6 on both sides to get x alone...
3x + 6 = 15
-6 -6
Then it is..
3x = 9
Lastly, divide by 3 on both sides...
3x = 9
3 3
Then it becomes
x = 3.
Then we see that both equations have x = 3, meaning when both x's = 3, then both equations will be equivalent. I hope this helps, and I hope it is not wrong, but I don't think it is.
Dora, the school lunch manager, says that it takes 225 oranges to make 5 gallons of orange juice how many oranges does Dora need to make one gallon?
Answer:
45
Step-by-step explanation:
Since
5 : 225 = 1 : X
Then we know
225/5 = X/1
Multiplying both sides by 1 cancels on the right
1 × (225/5) = (X/1) × 1
1 × (225/5) = X
Then solving for X
X = 1 × (225/5)
X = 45
Therefore
5 : 225 = 1 : 45
Answer:45
Step-by-step explanation:well all you do is divide 5 from 225

A family built a house in a beach resort area. In 1990, the house was 430 ft from the water. With erosion, the house was 400 ft from the water in 2000. In what year will the house be only 250 ft from the water?
a. 1990
c. 2015
b. 2004
d. 2050
We develop an equation for the given situation by first writing the general equation for lines,
y = mx + b
Substituting to this given the values given above,
(1990) 430 = b
(2000) 400 = m(10) + 430
The value of m from the equation in 2000 is -3. Thus, the equation of that relates the variables is,
y = -3x + 430

Congruence Theorem only when x = |
Answer:
[tex] \overline{AC} [/tex] is congruent to [tex] \overline{DF} [/tex], because [tex] \overline{AC} = 9in [/tex], [tex] \overline{DF} = 8 in [/tex]. <C is congruent to <F. [tex] \overline{EF} [/tex] must correspond to [tex] \overline{BC} [/tex]. The triangles are congruent by the SAS Triangle
Congruence Theorem only when x = 4.
Step-by-step explanation:
From the figures given, ∆ABC and ∆DEF have an included corresponding angles measuring 30° each (<C and <F), and also a given corresponding side length of 9 in each (side AC and side DF). The other given as am expression, and hence the length is unknown. For these two ∆s to be considered congruent, using the SAS Triangle Congruence Theorem, we must have two sides and an included angle of ∆ABC equal to the corresponding sides of and an included angle of ∆DEF.
We already know that 1 of the given side corresponding side lengths are equal and also the include angles are equal, to find out what value of x that will make both unknown corresponding lengths equal, in other for the SAS to be true, set 2x equal to (x + 4) to solve for x.
Thus:
2x = x + 4
Subtract x from both sides
2x - x = 4
x = 4
Substituting x = 4 into 2x and x + 4 will give us equal lengths of 8 in respectively. Therefore, if x = 4, both triangles will be congruent based on the SAS Triangle Congruence Theorem.
The answer is:
[tex] \overline{AC} [/tex] is congruent to [tex] \overline{DF} [/tex], because [tex] \overline{AC} = 9in [/tex], [tex] \overline{DF} = 8 in [/tex]. <C is congruent to <F. [tex] \overline{EF} [/tex] must correspond to [tex] \overline{BC} [/tex]. The triangles are congruent by the SAS Triangle
