Pls help and show your work for brainlist .

Answers

Answer 1

Answer:

R=? D=? C=\pi[/tex]

Step-by-step explanation:

R is a radius, the radius is a line segment from the center of a circle.

D is a distance around. Another word for D is the perimeter.

Pi is a circle's circumference (Which never ends.)

For example: 3.1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679...

And the pi is 31,415,926,535,897.

Pi meaning is a half-radius x half-radius x circumference.

I hope that helps :D

John ratio. Susan

s : m : L s : m : L

65 : 40 : 45. 13 : 8 : 9

13 : 8 : 9. x : 176 : y

x = (176/8)*13

=286

y = (176/8) * 9

Answers

Answer:

Step-by-step explanation:

Circumstance of a curcle C=2*pi*r

So if you want to find r from this equation you come up with r=C/2*pi. That's exactly what they give you in the problem.

Now you know that C= 26.69 so replacing what we know in the formula r=C/2*pi you get

r=26.69/2*3.14 =4.25

So looking at the figure you they said r=4.25

That means that the figure is has to be a circle.

Hope that makes sense.

What is the width of this rectangular prism if the volume is 162 cm cubed?

Step-by-step explanation:

Volume is lxwxh, 6x9= 54, and 54x3=162

Answer: 3

Step-by-step explanation:

The equation for volume of a rectangular prism is lwh. We have the lh and 6 times 9 is 54. Now we just divide 162 and 54 and that's the width which is 3. And to double check 3 times 9 times 6 is 162 :)

Answer:

x = 5

Step-by-step explanation:

4x + 2y + z = 24

2x - 3y - z = 2

5x + y + 2z = 21

-----------------

Eliminate z

Add the 1st and 2nd eqn

4x + 2y + z = 24

2x - 3y - z = 2

----------------

6x - 1y = 26 eqn A

Multiply the 2nd eqn by 2, then add the 3rd.

4x - 6y -2z = 4

5x + y + 2z = 21

----------------

9x - 5y = 25 eqn B

---------------

Now you have 2 eqns in 2 unknowns, not 3.

Multiply eqn A by 5 and subtract eqn B.

30x - 5y = 130 eqn A times 5

9x - 5y = 25 eqn B

-------------

21x = 105

x = 5

Answer:

x = 5 is the answer

Three ropes of length 2 m 84 cm, 4 m 26 cm and 7 m 10 cm are to be cut into small pieces of equal length. What is the greatest possible length of each equal part, so that there is no wastage? How many pieces are there in total?

Answers

1 m 42 cm, there would be 10 pieces in total. i believe this is right.

The greatest possible length of each piece is 2 cm.

What is HCF?

The highest common factor is defined as the set of numbers with the highest common multiple. The highest positive integer with more than one factor in the set is HCF.

Three ropes of length 2 m 84 cm, 4 m 26 cm, and 7 m 10 cm are to be cut into small pieces of equal length.

We have been given the lengths of the ropes as

2 m 84 cm = 284cm

4 m 26 cm = 426cm

7 m 10 cm= 710 cm

We have to determine the greatest possible length of each equal part So that there is no wastage

So the greatest possible length of each piece will be the HCF of the length of the ropes.

⇒ 284 = 2× 142

⇒ 426 = 2 × 213

⇒ 710 = 2 × 355

Hence, the HCF of the 284, 426, and 710 is 2.

Therefore, the greatest possible length of each piece is 2 cm.
