Circle theorems help please

Answer:

(7 , - 0.5)

Step-by-step explanation:

(8 , -6) ;  (6, 5)

[tex]Midpoint = (\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2})\\\\ =(\frac{8+6}{2},\frac{-6+5}{2})\\\\=(\frac{14}{2},\frac{-1}{2})\\\\=(7 , -0.5)[/tex]

Answer:

If we say the circumference is 1600 pi, and this is equal to pi times the diameter, we can just divide both sides by pi to get the diameter, which is going to be 1600.

Step-by-step explanation:

Circles are all similar, and "the circumference divided by the diameter" produces the same value regardless of their radius. This value is the ratio of the circumference of a circle to its diameter and is called π (Pi).

Step-by-step explanation:

Alyssa starts with $40 and saves $10 each week. This can be written as:

= 40 + 10x

Bill has $24 and saves $12 each week. This can be written as:

= 24 + 12x

where, x = number of weeks

a. Bill will never have more money than Alyssa.

False.

From the 9th week, Bill will have more money than Alyssa. To check goes below.

Alyssa = 40 + 10x = 40 + 10(9) = 40 + 90 =$130

Bill = 24 + 12x = 24 + 12(9) = 24 + 108 = $132

b. Bill's savings can be represented by the equation = 12 + 24 where x is the number of weeks and y is his savings.

False.

Bill savings can be represented by:

= 24 + 12x

where, x = number of weeks

c. Alyssa and Bill will have the same amount of money at Week 6.

False.

Alyssa = 40 + 10x

= 40 + 10(6)

= 40 + 60

= $100

Bill = 24 + 12x

= 24 + 12(6)

= 24 + 72

= $96

Answer:

[tex]100.59\ \text{miles}[/tex]

Step-by-step explanation:

The distance traveled by Dylan every day is 4.79 miles

Let the number of days he went to school be [tex]x[/tex]

Distance traveled by Dylan in a month is given by

[tex]y=4.79x[/tex]

Total number of days Dylan went to school last month is 21

The distance traveled by Dylan last month was [tex]y=4.79\times 21=100.59\ \text{miles}[/tex]

Answer:

B

Step-by-step explanation:

The angle at the centre is equal to the arc that subtends it , thus

∠ ABC = arc AB = 75° → B

Answer:

A) The number of wallpapers needed to cover the walls is 6 double roll wall papers

B) The number of wall paper border rolls needed is 3 rolls

Step-by-step explanation:

A) The given parameters are;

The dimensions of the room are 9 ft. by 12 ft. by 8 ft. high,

The area one double role wallpaper covers = 60 ft.²

Therefore, we have;

The area of the room wall = 12 × 8 × 2 + 9 × 8 × 2 = 336 ft²

The number of double rolls of wallpaper to be used = Area of wall/(area of wallpaper) = 336/60 = 5.6

Therefore, given that the wall papers are sold in single units, we round up to the next whole number of units to get;

The number of wallpapers needed to cover the walls = 6 double roll wall papers

B) The borders of a wallpaper are installed parallel (and installed along) to the ceiling line

Therefore, the amount of wallpaper border required is given as follows;

Wall paper border length required = 2 × Length of the room + 2 × Width of the room

∴ Wall paper border length required = 2 × 9 ft. + 2 × 12 ft. = 42 ft.

The size of each wall paper border sold = 5 yd. = 15 ft.

Therefore;

The number of wall paper border rolls required = 42 ft./(5 yd.) = 42 ft./(15 ft.) = 2.8 rolls

Therefore, we round up to get the number of wall paper border rolls needed as 3 rolls of wall paper borders.

4x+y=9

4(2)+(1)=9

8+1=9

9=9

It is a solution

Answer:

9=9

Step-by-step explanation:

Solution:

x = 2

y = 1

4x+y=9

4(2) + (1)=9    (here 4 and 2 are multiplying with each other, so 4x2= 8)

8+1=9

9=9

Answer:

Amphibians! In order for water-dwelling animals to adapt to life on land, many new adaptations had to take place. First, they needed to be able to breathe air instead of obtaining oxygen from water. And fins don't work well as legs! They needed to be able to move around well on land.

What group of animals begins its life in the water, but then spends most of its life on land? Amphibians! Amphibians are a group of vertebrates that has adapted to live in both water and on land. Amphibian larvae are born and live in water, and they breathe using gills. The adults live on land for part of the time and breathe both through their skin and with their lungs as their lungs are not sufficient to provide the necessary amount of oxygen.

There are approximately 6,000 species of amphibians. They have many different body types, physiologies, and habitats, ranging from tropical to subarctic regions. Frogs, toads, salamanders , newts, and caecilians are all types of amphibians.

Answer:

I think 100$

Step-by-step explanation:

I can't be to sure

Answer:

900 dollars

Step-by-step explanation:

This is pretty easy

We know 10 percent off

so we can make an equation

0.1x=90

Then just solve

x=900

So 900 dollars

We can check by use finding 10 percent of 900

which is 90

SO its correct

Step-by-step explanation:

1+red/3=4/1 so 1+red=12 so red=11. we should add 11 red counters

Answer:

Add 15 red counters

Step-by-step explanation:

Number of red counter is 1

Number of blue counter is 3

1:3⇒4:1

Now to make ratio reverse you need to add 11 (12-1) more red counters so that ratio becomes

12:3=4:1

hope this helps

Answer:

A' = (-1, -1)

Step-by-step explanation:

Rule for the dilation of any point A(x, y) about the origin by a factor of k is given by the rule,

A(x, y) → A'(kx, ky)

From the graph attached,

Coordinates of point A are (-3, -3) and it is dilated by a scale factor of [tex]\frac{1}{3}[/tex] about the origin then the coordinates of the image point A' will be,

A(-3, -3) → [tex]A'(-3\times \frac{1}{3},-3\times \frac{1}{3})[/tex]

             → A'(-1. -1)

Therefore, coordinates of A' = (-1, -1) is the answer.

Answer:

1800

Step-by-step explanation:

suppose the initial cost to be x

it was increased by 6.5%

so, since the price increased is 117

117=6.5% of x

117=(6.5/100) . x

117 . 100=6.5 x

x=11700/6.5

x=1800

Answer:

Answer of this equation is (x-2)^2/ (X+3)^2

Step-by-step explanation:

x^2-4/X+3 × x-2/ x^2+5x+6

(X+2)(x-2) / X+3 × x-2/ x^2+(2+3)X+6

(X+2)(x-2)/X+3 × x-2/(X+2)(X+3)

(x-2)(x-2)/(X+3)(X+3)

(x-2)^2/(X+3)^2

CF = 16

Step-by-step explanation:

BCDE is a parallelogram. CE and BD are its diagonals.

Diagonals of a parallelogram bisects each other.
