The diameter of a circle is 20 m. Find its area in terms of π

Answers

Answer:

100π m^2

Step-by-step explanation:

Given data

Diameter= 20m

Radius= 10m

The expression for the  area is

Area= πr^2

Area= π*10^2

Area= π*100

Area= 100π m^2

Hence the area is 100π m^2

Nancy and Fabian’s dinner bill at a restaurant is $28 before tax. The tax on their meal is 2.5%.

The amount that Nancy and Fabian’s final bill after tax is added will be $28.70.

What is the percentage?

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

Nancy and Fabian’s dinner bill at a restaurant is $28 before tax. The tax on their meal is 2.5%.

Let "T" be the final bill. Then the equation is given as,

2.5% = [(T - $28) / $28] x 100

0.025 = (T - $28) / $28

T - $28 = $0.70

T = $28.70

The amount that Nancy and Fabian’s final bill after tax is added will be $28.70.

Answers

Answer:

12 days, 72 tickets

Step-by-step explanation:

the x coordinate of the vertex (aka the number of days it takes to peak) is equal to -b/2a, where b is the coefficient of the second term and a is the coefficient of the first term. That is equal to -9.6/2*-0.4 = 12.

plug 12 in for x to get -0.4*12^2+9.6*12+14=71.6, which rounds to 72.

The slating palace charges a $6.00 shoe rental fee plus $2.00 an hour to skate.Mathland skating rink charges $4.00 an hour to skate . what equation represents situation on;the skating palace

Answers

Answer:

Equation for the skating palace

= 6 + 2x

Step-by-step explanation:

Let the number of hours = x

For skating palace, the equation is written as:

The slating palace charges a $6.00 shoe rental fee plus $2.00 an hour to skate.

$6 + $2 × x

= 6 + 2x

For Mathland , the equation is written as:

Mathland skating rink charges $4.00 an hour to skate .

$4 × x

= 4x

Therefore, the equation that represents the situation on the skating palace is :

6 + 2x

A camera has a listed price of $511.99 before tax. If the sales tax rate is 7.75%, find the total cost of the camera with sales tax included.
Round your answer to the nearest cent, as necessary,

Answers

Answer:

$551.70

Step-by-step explanation:

Price before tax= $511.99

Cost of the tax= 7.75/100×511.99

= $39.679

Total cost of the camera= $511.99+$39.679

= $551.669

≈ $551.70

Geometry please help.

Answers

Answer:

CD = 16

Step-by-step explanation:

We can see that both AC and AB are radii. This means that they are equal, so AC = AB = 17. From segment addition postulate we can say AB = AE + BE

We are given BE, and we found the length of AB, so we can substitute and solve for AE:

AB = AE + BE

17 = AE + 2

AE = 15

Since we are given that AB is perpendicular to CD, ∠AEC would be a right angle, making ΔAEC a right triangle.

Now, we can use the pythagorean theorem to find the length of CE.

a^2 + b^2 = c^2

We are given the hypotenuse, c or AC in this case, and one leg, b, or AE in this case. We can plug in the values we are given:

CE^2 + AE^2 = AC^2

CE^2 + 15^2 = 17^2

CE^2 + 225 = 289

CE^2 = 64

CE = 8

Now, if a chord is perpendicular to a radius(AB in this case) we can say that it is split in half by the radius. This is basically saying that CE = DE = 8.

Again, using segment addition postulate, we can say:

CE + DE = CD

CD = 8 + 8

CD = 16

Answers

Answer:
8π yards
Step-by-step explanation:
A circle subtends a total angle of 360 ° from its center.The length of an arc is directly proportional to the angle it subtends from the circle's center. The arc's length can therefore be calculated as:
C=πd=2πr
Where C is circumference, d is diameter and r is radius. Given r as 16 yards then the arc length which is equivalent to circumference is given as

between 21 and 30 pounds in shelter A between 18 and 28 pounds in shelter B

between 28 and 30 pounds in shelter A between 20 and 28 pounds in shelter B

Answers

Answer:

between 21 and 30 pounds in shelter A between 18 and 28 pounds in shelter B

Step-by-step explanation:

One half of the dogs in each shelter points at the the upper 50% of the dog weight. This point is marked by the median value up to the maximum weight value.

The median value is the point marked inside the box on a boxplot and the maximum value is the upper end or the endpoint of the whisker.

For SHELTER A:

Median = 21

Maximum = 30

Hence, For shelter A, it is the interval between 21 and 30

For shelter B:

Median = 18

Maximum = 28

Hence, it is the interval between 18 and 28

But, indeed, sir, we make holiday,to see Caesar and to rejoice in his triumph.MARULLUS Wherefore rejoice? What conquest brings he home?What tributaries follow him to Rome,To grace in captive bonds his chariot-wheels?You blocks, you stones, you worse than senseless things!O you hard hearts, you cruel men of Rome,Knew you not Pompey? Many a time and oftHave you climb'd up to walls and battlements,To towers and windows, yea, to chimney-tops,Your infants in your arms, and there have satThe livelong day, with patient expectation,To see great Pompey pass the streets of Rome:And when you saw his chariot but appear,Have you not made an universal shout,That Tiber trembled underneath her banks,To hear the replication of your soundsMade in her concave shores?And do you now put on your best attire?And do you now cull out a holiday?And do you now strew flowers in his wayThat comes in triumph over Pompey's blood?

There is the sense of action, as it depicts the triumphant return of Julius Caesar to Rome. Caesar, dressed in formal robes, is positioned to the right of the painting on his golden chariot riding through the streets with the Arch of Constantine in the background against blue skies and an adoring attendant in the foreground on the left carrying the victory banner that reads 'VENI VIDI VICI' (translation: I came, I saw, I conquered). The left side only is framed by an elaborate faux column, while the others are left simple. In the traditional image, Caesar sits high up on the chariot behind his white horse. He is holding a staff and a large feather, while an angel is depicted behind him placing a headdress upon his head. People mill around between the cart and the Arch watching the procession while cherubs offer branches of victorious recognition in the foreground. Public DomainIn at least two to three paragraphs, write an essay where you analyze the tone the character Marullus uses to express his interpretation of Caesar's return. Then explain how this is similar or different from the interpretation the painter has depicted? Use specific examples to support your observations. Use proper spelling and grammar.
