The figures below are based on semicircles and squares. Find the perimeter and the area of each shape. Give your answer as a com

irina1246 [14]

Answer:

Part 1) The area of the figure is $A=48\ cm^2$

Part 2) The perimeter of the figure is $P=4(2+3\pi)\ cm$

Step-by-step explanation:

Part 1) Find the area of the figure

we know that

The area of the figure is equal to the area of three squares

$A=3[4^2]=48\ cm^2$

Part 2) Find the perimeter of the figure

we know that

The perimeter of the figure is equal to two times the length side of the square, plus the circumference of six semicircles ( or the circumference of three circles)

Remember that

The circumference of a circle is equal to

$C=\pi D$

where

D is the diameter of the circle

In this problem

$D=4\ cm$

$P=2(4)+3[\pi(4)]=(8+12\pi)\ cm$

simplify

$P=4(2+3\pi)\ cm$

Alekssandra [29.7K]

Answer:

Each person will get $\frac{7}{30}\ lb$

Step-by-step explanation:

we know that

To find out how much chicken will each person get, divide the total pounds of chicken by the number of persons

$\frac{7}{10}:3$

Multiply in cross

$\frac{7}{10*3}=\frac{7}{30}\ lb$

Giselle pays $220 in advance on her account at the athletic club. Each time she uses the club,

ale4655 [162]

Answer:

$y=220-15x$

Step-by-step explanation:

Let x represent the number of times Giselle uses the athletic club and y represent money left in account.

We have been given that each time she uses the club, $15 is deducted from the account. The amount used after using the club after x times would be $15x$ .

We are also told that Giselle pays $220 in advance on her account at the athletic club.

The money left in account after x uses of athletic club would be money in account initially minus amount used for using the club x times.

$y=220-15x$

Therefore, our required equation would be $y=220-15x$ .

How do I simplify this?

ololo11 [35]

Don't get too involved in the 'simplify' part just yet.
It doesn't mean make the problem easier.
It means that when you have the answer, make sure it's in simplest form.
That's why it says "Simplify your answer".
Notice that that's the 2nd instruction.
There's nothing to simplify until you have an answer.

The first thing you have to do here is find the area of a triangle.
Do you remember that formula ?
I'll bet you do.
The area of a triangle is (1/2) · (length of the base) · (height) .

The height and the length of the base are given, right there
in the picture. Take those, and use them to find the area.

Once you've multiplied the binomials, don't forget about the (1/2).

Finally, you have a trinomial for an answer.
Put the big sweet cherry on top: Factor it !
I think that's the 'simplify' part.

You may be surprised.
I was when I worked it out just now ... just for you.
