find the distance of a cord 8cm from the centre of a circle of a radius 5 cm​

Answers

Answer 1

Answer:

d = 3 cm

Step-by-step explanation:

Given that,

The distance of a cord, c = 8 cm

The radius of the circle, r = 5 cm

Half of the cord = 4 cm

We need to find the distance of a cord from the centre of the circle. We can find it using Pythagoras theorem,

[tex]5^2=d^2+4^2\\\\d^2=25-16\\\\d=3\ cm[/tex]

So, the required distance is 3 cm.

Mark is making jackets. Mark took 2 hours to make a jacket. The jacket was made up of 50 kilograms of wool. How long do you think it will take Mark to use 500 kilograms of wool for the jackets?

Answers

Given:

Mark took 2 hours to make a jacket.

The jacket was made up of 50 kilograms of wool.

To find:

The time in which Mark use 500 kilograms of wool for the jackets.

Solution:

We have,

1 jacket take 2 hours.

Number of jackets in 50 kg of wool = 1

Number of jackets in 1 kg of wool = [tex]\dfrac{1}{50}[/tex]

Number of jackets in 500 kg of wool = [tex]\dfrac{1}{50}\times 500[/tex]

                                                              = [tex]10[/tex] Jackets

Time taken by 1 jacket = 2 hours

Time taken by 10 jacket = 20 hours

Therefore, it will take 20 hours to use 500 kilograms of wool for the jackets.

Answer:

20 hours

Step-by-step explanation:

1 jacket=50kg wool

1 jacket= 2hrs

500kg available/50kg per jacket= 10 jackets

10 jackets x 2hrs per jacket=20hrs

what is angle a and c if b is 63 degrees? You will get 100 points for answering please help

Answers

Answer:

Angle A measures 76°

Step-by-step explanation:

The three interior angles of a triangle will always equal 180. Therefore:

[tex](63)+(x+7)+(2x+8)=180[/tex]

Solve for x. Add and combine like terms:

[tex]78+3x=180[/tex]

Subtract 78 from both sides:

[tex]3x=102[/tex]

Divide both sides by 3. So, the value of x is:

[tex]x=34[/tex]

Angle A is given by:

[tex]m\angle A=2x+8[/tex]

Since we know that x = 38:

[tex]m\angle A=2(34)+8=76[/tex]

Angle A measures 76°

Answer:

20. multiply both sides by 4, x= 24

21. multiply both sides by 7, y=21

22.multiply both sides by 5, z=20

23. multiply both sides by 6, p=12

24. multiply both sides by 2, r=8

Step-by-step explanation:

you want to get the variable alone (x,p,y, etc).

so if you are dividing the variable by a number you want to take the denomentator and multiply it by itself and then you have to multiply the same number to the number on the other side of the equation.
