Answer and Step-by-step explanation:
We are told that the circumference is 20, and we are asked to find the area.
The equation for circumference is:
C = 2[tex]\pi[/tex]r
We can plug in 20 and solve for r.
20 = 2[tex]\pi[/tex]r
Divide by 2 on both sides.
10 = [tex]\pi[/tex]r
Now divide by [tex]\pi[/tex] on both sides.
[tex]\frac{10}{\pi }[/tex] = r
Now, we can plug this into the area equation:
A = [tex]\pi[/tex][tex]r^{2}[/tex]
A = [tex]\pi[/tex][tex](\frac{10}{\pi } )^{2}[/tex]
A = [tex]\pi[/tex][tex]\frac{100}{\pi ^{2} }[/tex]
A = [tex]\frac{100\pi }{\pi ^{2} }[/tex]
A = [tex]\frac{100}{\pi }[/tex]
Now, we put this into the calculator to solve.
We get:
31.830988618379067153776752674503
We are then told to round to the nearest whole number.
8 is greater than 5, so we round up.

The expression 8x + 2(3y) represents the total amount, in dollars, that Davellyn spent on tank tops and scarves, where x represents the number of tank tops she bought and y represents the number of scarves she bought. Which statement must be true about the amount Davellyn spent?
She spent 8x dollars on scarves.
She spent 8 dollars for each scarf.
She spent 6y dollars on scarves.
She spent a total of 14 dollars.
Answers
Answer:
She spend 6y dollars on scarves.
Step-by-step explanation:
The question states that y represents the number of scarves she bought, so the first and second statements would be incorrect. You don't know how much she spent in total, so the fourth statement would also be wrong. So it's the third statement.
Also, you can just do 2*(3y), which is 6y.

D. AXT
E TAX
F.XTA
Answers
There are three valid names for the given triangle AXT, TAX, and XTA.
A triangle is a 3-sided polygon that is occasionally (though not frequently) referred to as the trigon. There are three sides and three angles in every triangle, some of which may be the same. In the case of a right triangle, the three sides are given unique names: the hypotenuse, which is the side that faces the right angle, and the legs, which are the other two sides. Every triangle is bicentric and convex. The triangle's interior is the area of the plane it encloses; the outside is the rest of the plane. Triangle geometry, as the study of triangles is frequently referred to, is a rich field of geometry that is full of stunning outcomes and surprising connections. Let S stand for a side of a triangle and A for an angle. Then, let a group of Ss and As be concatenated so that adjacent letters stand for adjacent sides of a triangle and adjacent angles. According to the SSS theorem, a triangle can only exist if it has three sides, two angles, and a side, or two sides and an adjacent angle (SAS theorem). The three unknown quantities (there are a total of three sides and three angles) can be uniquely identified in each of these situations. Other side and angle combinations do not necessarily result in a triangle being formed: the AAA theorem states that three angles specify a triangle but only up to certain scale size and that one angle and two sides without it may describe one, two, or no triangles.

Which of the following is an annual expense?
A)car insurance
B)electric bill
C)savings
D)rent
Answers
Among the given options, the annual expense would be A) car insurance
Car insurance is typically paid on an annual basis, providing coverage for potential damages or accidents involving the insured vehicle.
The policyholder pays a premium to the insurance company, which covers the cost of the insurance over the course of a year.
The other options listed, such as the electric bill (Choice B), savings (Choice C), and rent (Choice D), do involve financial transactions, but they may occur on different schedules.
The electric bill is typically a monthly or quarterly expense, while savings is a personal financial strategy involving setting aside money regularly. Rent is usually paid on a monthly basis for the use of a property.
Car insurance is the option that specifically relates to an annual expense, as it is a recurring payment made once a year for the coverage of an insured vehicle.
Correct option is A)car insurance.

Multiplicative inverse of any number is the reciprocal of that number.

The answer is B, C, and D. Like terms are terms with all the same variable, so 5x and -x are like terms.
C is correct. If we add -x to 5x, we get 4x. The other numbers remain unchanged because they have no like terms.
D is correct. Applying the rule of like terms, which is that like terms are numbers with the same variable, only add together numbers with the same variable.

Thomas draws a triangle with side lengths of 5 centimeters and 12 centimeters and one angle of 90°. The length of the longest side of the triangle is not known. How many different triangles can be drawn with these dimensions? Explain your reasoning.
Answers
Step-by-step explanation:
Thomas draws a triangle with side lengths of 5 centimeters and 12 centimeters and one angle of 90.
If one of the angle is 90 degrees, it would mean that he has drawn a right angle triangle.
Hypotenuse is the longest side of the triangle. We can find it using Pythagoras theorem as follows:
[tex]h=\sqrt{5^{2}+12^{2}}\\\\=13[/tex]
The longest side is 13 cm.
If we keep the longest side the same and if two sides i.e. 5 cm and 12 cm are replaced, a new triangle can form.
The distance between 2 cities is 145 miles . A truck can cover this distance in 2.5 hours. A car is a.5 times as fast as the moving truck. How long does it take to meet, if they start moving simotanously
Answers
Answer:
25 minutes
Step-by-step explanation:
Given that:
Distance between 2 cities = 145 miles
Time taken by truck = 2. 5 hours
Speed of car = 5 times the speed of truck
Speed of truck = distance / time
Speed of truck = 145 / 2.5
Speed of truck = 58 mph
Speed of car = 5 * 58 = 290 miles per hour
Time it takes to meet :
Time taken = distance / combined speed
Time taken = 145 / (290 + 58)
Time taken = 145 / 348
Time taken = 0.4166666 hours
Time taken = 0.4166666 * 60 = 25 minutes
Find the percent of change from 74 hours to 85 hours.

Answers
Answer:
The factored form of x²-400 is (x+20)(x-20).
Step-by-step explanation:
Given the expression
[tex]x^2\:-\:400[/tex]
As the square of 20 is 400. Therefore, rewrite 400 as 20²
⇒ [tex]x^2-20^2[/tex]
[tex]\mathrm{Apply\:Difference\:of\:Two\:Squares\:Formula:\:}x^2-y^2=\left(x+y\right)\left(x-y\right)[/tex]
Thus, the expression becomes
[tex]x^2-20^2=\left(x+20\right)\left(x-20\right)[/tex]
Thus, the factored form of x²-400 is (x+20)(x-20).
