11. On a basketball court, the free throw lane is marked off geometrically. This area of the court is called the


key and is topped by a semicircle that has a diameter of 12 feet. Find the arc length of the semicircle to the


nearest foot. Find the area of the semicircle to the nearest square foot.

Based on the number of sides, polygons are categorized as triangles, quadrilaterals, pentagons, hexagons, octagons, nonagons, and decagons, which have 3, 4, 5, 6, 7, 8, 9, and 10 sides, respectively.

Any closed curve that has a collection of connected line segments (sides) that do not cross each other is a polygon in geometry. Pentagons, quadrilaterals with four sides, and triangles with three sides make up the most basic polygons (five sides).

The closed, side-and-vertex-containing shapes are known as polygons.

example

If any segment of a diagonal has points outside the polygon, the polygon is considered concave. The polygon is convex if none of the outside diagonals include any points.

Answer:

\(-\frac{1}{55}\)

Step-by-step explanation:

Hi! Ace here.

Whenever we have a positive being added to a negative, we can just do the positive subtracted my negative.

So let's rewrite this:

\(\frac{4}{5} -\frac{9}{11}\)

When subtracting and adding fractions, we have to make sure there is a common denominator, and if there isn't a common denominator, then we make a common denominator. The LCM, in this case, is 55, so let's convert the fractions.

\(\frac{4}{5} *\frac{11}{11} =\frac{44}{55}\)

\(\frac{9}{11} * \frac {5}{5} = \frac{45}{55}\)

Since \(\frac{11}{11}\) and \(\frac{5}{5}\) both equal 1, the fraction is the same value.

Now we subtract normally with our "new" numbers.

\(\frac{44}{55}- \frac{45}{55}\)\(=-\frac{1}{55}\)

I hope this helped, let me know if you have any questions.

Basic Operations. The basic arithmetic operations for real numbers are addition, subtraction, multiplication, and division.

Step-by-step explanation:

The measure of the angle A in the ΔACD is 13.26°.

Given a triangle ACD with angle D = 35°, AC = 20, DC = 8, we need to find the measure of the angle A,

So, using the Sine Law,

Sin D / AC = Sin A / CD

Sin 35° / 20 = Sin A / 8

Sin A = Sin 35° / 20 × 8

A = Sin⁻¹(Sin 35° / 20 × 8)

A = 13.26°

Hence the measure of the angle A in the ΔACD is 13.26°.

The solution is, the finally discounted price is 71.5.

A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

here, we have,

sale price = 90

15% discount, so, the price = 90* 85%

                                            =76.5

now, after 5 discount, price became = 76.5 - 5

                                                             = 71.5

Answer:

4 rolls

Step-by-step explanation:

We can use logic to find how many rolls of toilet paper you would need.

If you use 10 sheets of toilet paper every time you use the toilet, and this happens 3 times a day, then each person per day uses \(10\cdot 3 = 30\) sheets of toilet paper per day.

For a 4 family household with 4 people, that would be \(30 \cdot 4 =120\) sheets every day for the whole family.

For a week (7 days) the whole family would use \(120 \cdot 7 = 840\) sheets per week.

If rolls of toilet paper are shipped by every 250 sheets, then we'd need \(840 \div 250 = 3.36\) rolls.

We can't have 0.36 of a roll, so we round up to 4 so we have enough.

Infinitely Many Solutions

Step-by-step explanation:

We can start by simplifying both sides of the equation:

2(12-w) = -2(w-17)-10

Expanding the brackets:

24 - 2w = -2w + 34 - 10

Simplifying:

24 - 2w = -2w + 24

At this point, we can see that both sides of the equation are equivalent, so we can conclude that the equation is an identity and has infinitely many solutions. Any value of w will satisfy the equation.

Answer:

Step-by-step explanation:

If the bigger triangle has the two congruent sides measuring 20, then the ratio of the bigger to the smaller is 20/5.6 This means that the ratio between the third side of the bigger to the third side of the smaller is 20/5.6

Setting a ratio:

20/5.6=x/4.2

Cross multiplying: 84=5.6x

x = 84/5.6  -->12/0.8 --> 15

Answer:

Step-by-step explanation:

The net force acting on the object is 3456 N, the objective with an acceleration.

The net force applied to an object is equal to the product of its mass and acceleration, according to Newton's second law of motion. Mathematically, this can be represented as:

Fnet = ma

Where Fnet is the net force, m is the mass, and a is the acceleration. In your scenario, the net force applied to the object is 125 N, and its acceleration is 24.0 m/s2. Therefore, we can rearrange the formula and solve for the mass of the object as follows:

m = Fnet / a
m = 125 N / 24.0 m/s2
m = 5.21 kg

However, this answer does not match the given mass of the object, which is 144 kg. This suggests that there may be an error in one of the values provided. Assuming the mass of the object is actually 144 kg, we can use the same formula to solve for the net force acting on it as follows:

Fnet = ma
Fnet = 144 kg * 24.0 m/s2
Fnet = 3456 N

#SPJ11

The mass of an object with net force value = 125 Newton and acceleration of 24.0 m/s² is equals to the 5.208 kg. So, option(c) is right one.

The force formula is derived by Newton's second law of motion. The basic formula force applied on object is F = ma, which implies that net force is equals to product of mass and acceleration of an object. We have an object with the following information, Net applied force on object, F = 125 N

Acceleration of an object, a = 24.0 m/s²

We have to determine mass of object. Using the above force formula, F = M× a

where M --> mass in kilograms

a --> Acceleration in m/s²

F --> net force in Newton

Substitute all known values in above formula, 125 N = M × 24.0 m/s²

=> M = = \(\frac{125}{24}\)

=> M = 5.208 kg

Hence, required value is 5.208 kg.
