Carl knows that the area of a given circle is 400 cm2. He wants to defend an informal argument that the area of a circle can be
Marizza181 [45]

ANSWER:

A. Carl could divide the circle into a larger even number of congruent sectors. Then each sector would be smaller, and the approximation of the circle’s area will be closer to the actual area of the circle.

STEP BY STEP EXPLANATION :

Area of a Circle by Cutting into Sectors:

1. Cut a circle into equal sectors and the more we divided the circle up, the closer we get to being exactly right.

2.Rearrange the sectors, which resembles a parallelogram.

What are the (approximate) height and width of the parallelogram?

The height is the circle's radius.

The width (actually one "bumpy" edge) is half of the curved parts around the circle. In other words it is about half the circumference of the circle.

We know that:

Circumference = 2 × π × radius

And so the width is about:

Half the Circumference = π × radius

ow we just multply the width by the height to find the area of the rectangle:

Area = (π × radius) × (radius)

= π × radius2

Conclusion

Area of Circle = π r2

. Ralph’s Fill Dirt and Croissant Shop in Spencer makes both grand and petit croissants. Each grand requires 1 ounce of flour an
Gwar [14]

Answer:

1

Step-by-step explanation:

let G be the number of grand croisssants, and P the number of petit croissants :

we have that 1 ounce of flour and 2 ounces of butter result in one G.

additionally, we have that 1/4 ounce of flour and 1/3 ounce of butter result in one P.

Ralph has 4 ounces of flour and 6 ounces of butter, If he bakes more than 1 G then he will never use all of his ingredients!, let's see:

1 G:

he now has 3 ounces of flour, and 4 ounces of butter,

now we need to figure out how many P's we would obtain with such amounts:

let x be the number of P's

1/4*x = 3=>x=12\\ 1/3*x=4=>x=12

which is reasonable, Ralph can bake 12 P's,

now with more than 1 G:

2G:

Ralph has now 2 ounces of flour and 2 ounces of butter, now we have to figure out that x is the same using the remaining ingredients

1/4*x = 2=>x=8\\ 1/3*x=2=>x=6

This is impossible.

3G:

he runs out of butter.

There is the answer, he is able to bake 1 grand croissant and 12 petit croissants

What is the solution to 7x+115=136?
lubasha [3.4K]

Answer:

x=3

Step-by-step explanation:

In order to solve this kind of equation, you need to be able to understand what the question is asking. This question is asking what value of X will make both sides equivalent to each other?

<em>In order to find out, you need to get X by itself. </em>

The first step is to subtract 115 from both sides.

7x+115=136

-115  |  -115

7x=21

Now, the X value is by itself with another value on the other. With this part, you need to divide both sides by 7.

7x=21

/7 | /7

x=3

This is because you have 7 X's and you need to have only 1 of the X's.

Let me know if this was helpful or if you need any more help. Have a nice day. :)
