Answer:  (x - 3)² + (y + 0.5)² = 3.25    →    [tex](x-3)^2+\bigg(y+\dfrac{1}{2}\bigg)^2=\dfrac{13}{4}[/tex]

Step-by-step explanation:

Concentric means they have the same center but different radii.

The equation of a circle is:  (x - h)² + (y - k)² = r²    where

(h, k) is the center of the circler is the radius of the circle

Complete the square to find the center of the circle

x² - 6x + _____  + y² + y + _____ = 1 + ____ + ____

    ↓                              ↓

-6/2 = -3                    1/2 = 1/2

Equation: (x - 3)² + (y + 1/2)² = r²

Since the circle passes through point (x, y) = (4, -2), input that into the equation to find r².

(x - 3)² +  (y + 1/2)² = r²

(4 - 3)² + (-2 + 1/2)² = r²

  (1)²    +  (-3/2)²    = r²

   1      +     9/4      = r²

                 13/4     = r²

Equation: (x - 3)² + (y + 1/2)² = 13/4    →   [tex](x-3)^2+\bigg(y-\dfrac{1}{2}\bigg)^2=\dfrac{13}{4}[/tex]

In decimal form: (x - 3)² + (y + 0.5)² = 3.25

Jaiden's pen pal from Mexico said that he lives 3.3 kilometers from school. Jaiden knows
that 1 kilometer is approximately 0.62 miles. Which is the closest distance (in miles) that
Jaiden's pen pal lives from school?

Answers

Answer:

2 miles

Step-by-step explanation:

3.3 kilometers to miles is 2.0505. I'm not sure if this question want you to round, but if it does, the answer would be 2 miles.

To get your approximate answer, multiply 3.3 (kilometers) by 0.62 (miles).

You get 2.046 if you multiply it by 0.62 like the question says to do.

Which statement best describes how Charlemagne expanded his territory in Europe? He led the Catholic Church as the Holy Roman emperor. He became king of the Franks and then conquered other lands. He created schools in the kingdom and then became emperor of Saxony. He created new laws that allowed him to become king of the Lombards and Saxons.

Answers

Answer:

He became king of the Franks and then conquered other lands.

Step-by-step explanation:

Charlemagne became king of the Franks after the death of his father, Pepin the Short.

He inherited a sizeable portion of land that included what is now France, the Low Countries, and parts of Germany.

Charlemange launched several military campaigns throughout his long reign (he ruled for 46 years), and was highly successful in most of them. He conquered Northern and Central Italy, what is now Switzerland and Austria, and the majority of modern day Germany.

He was crowned Holy Roman Emperor in the year 800 by Pope Leo III. In exchange for this, Charlemange ceded a section of Central Italy to the Pople: the Papal States, which would be under direct control of the Roman Catholic Church until the Napoleonic Era.

Step-by-step explanation:

Given

[tex]XYZ = 2X[/tex]

[tex]PQR = 8X - 20[/tex]

Find PQR

Since both angles are supplementary, we have:

[tex]XYZ + PQR = 180[/tex]

This gives:

[tex]2X + 8X - 20 = 180[/tex]

[tex]10X - 20 = 180[/tex]

Water flowed out of a tank at steady rate. A total of 18 1/2 gallons flowed out of a tank in 4 1/4 hours. Which expression determines the the quality of water leaving the tank per hour?
O 17/4 divide 36/2
O 36/2 divide 17/4
O 17/4 divide 37/2
O 37/2 divide 17/4

Answers

Answer: In 1 hour water flowed out = 74/17  gallons

Step-by-step explanation:

Given as ,

The quantity of water flowed out of tank =  18 1/2 gallons

                                                                  =   37/2   gallons

The time spend in flowing water out of tank = 4  1/4 hours

                                                                         =   17/4   hours

∵ In   17/4 hours , water flowed out = 37/2

∴ In    1    hours                           ,  water flowed out =

So, in 1 hour water flowed out =  37*4/17*2 gallons Answer

Answer:

total galloons flowed=18 1/2=36/2

time that it flowed=4 1/4=16/4

rate=total galloons flowed/time to flow

rate=36/2÷16/4

=9/2gallons per hour

Single-tickets sell for $20 each and a couple-tickets for $35 each. A total of 160 tickets are
sold, and the total value of the ticket is $4100. How many of each kind of ticket were sold?

Answers

Answer:

100 of the 20$ tickets, and 60 of the 35$ tickets

Step-by-step explanation:

20*x + 35*y = 4100

x + y = 160

That means x = 160 - y, put this into the first equation

20(160 - y) + 35y = 4100

3200 - 20y + 35y = 4100

15y + 3200 = 4100

15y = 900

y = 60

Put y = 60 into the second equation and

x + 60 = 160

x = 100

y = 60, x = 100

Double check that this works for both equations to make sure its right

20 * 100 + 35 * 60= 4100

2000 + 2100 = 4100 /Correct

100 + 60 = 160 /Correct

PLZ HELP, GIVING BRAINLIEST!! A swimmer dives straight into the ocean. His depth, d, in meters after t seconds, can be modeled using the equation d = (t - 3)^2 - 16 What is the lowest depth the swimmer reaches? How long does it take the swimmer to reach the lowest depth? a. 9 feet, 16 seconds b. 16 feet, 3 seconds c. 3 feet, 16 seconds d. 16 feet, 9 seconds

Answers

I think it’s d because if you plug in 16 for d and solve for t, t is about 9, it’s the only one that’s closest to true, but you can try plugging them in and checking it

The time taken by the swimmer to reach the lowest depth will be 9 seconds. The correct option is D.

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that a swimmer dives straight into the ocean. His depth, d, in meters after t seconds, can be modeled using the equation d = (t - 3)² - 16.

The time will be calculated as below;-

d = ( t - 3 )² - 16.

16 = ( t - 3 )² - 16

32 =  ( t - 3 )²

√32 = t - 3

5.67 = t - 3

t = 5.67 + 3 = 8.67 ≅ 9 seconds

Therefore, the time taken by the swimmer to reach the lowest depth will be 9 seconds. The correct option is D.
