Juan = J

Carmen = C

J+C = 24

J = 3C          Substitute this onto J

3C + C = 24              

4C = 24

C = 6

J = 18

A circle circumference is 600 M. what is the good approximation of the circle area​
wlad13 [49]

Answer:

The area of the circle is 28662 M².

Step-by-step explanation:

Given:

Circumference of circle = 600 M.

Now, to find the area of the circle.

So, <em>to get the area we need to find the radius.</em>

By putting the formula of circumference we get the radius:

Let the radius be r.

Circumference = 2πr

600 = 2\times 3.14\times r (taking the value of π = 3.14.)

600=6.28r

Dividing both sides by 6.28 we get:

95.54=r

Now, <em>for getting the area we put the formula:</em>

Area = πr²

Area = 3.14\times 95.54^{2}

Area = 3.14\times 9127.89

Area = 28661.57

So, <u><em>approximately the area of  the circle = 28662 M²</em></u>.

Therefore, the area of the circle is 28662 M².

nikitadnepr [17]

Answer:

The jeweler made 11 bracelets and 7 necklaces.

Step-by-step explanation:

Given that a jeweler had a fixed amount of gold to make bracelets and necklaces, and the amount of gold in each bracelet is 6 grams and the amount of gold in each necklace is 16 grams, knowing that the jeweler used 178 grams of gold and made 7 more necklaces than bracelets, to determine a system of equations that could be used to determine the number of bracelets made and the number of necklaces made, the following mathematical reasoning should be considered:

(16 - 6) x 7 = 70

178 - 70 = 108

108/6 = 18

18 - 7 = 11

(11 x 6) + (7 x 16) = X

66 + 112 = X

178 = X

Thus, the jeweler made 11 bracelets and 7 necklaces.
