Nathan is collecting aluminum cans for charity. One empty 355 ml can weighs about 17 g. It takes 59 cans to get about 1 kg of 10

0% recyclable aluminum.
Over one month, he collected 1978 cans.


What is the mass, in kilograms, of these cans?

Answer:

33.5 kg

Step-by-step explanation:

Each 59 cans are about 1 kg.

He collected 1978 cans.

How many times 59 cans did he collect?

1978/59 = 33.5

He collected 1978 cans which is 33.52 times 59 cans, so he collected 33.5 kg

<h3>Answer:</h3>

The circle makes the larger area

The difference in the two areas is roughly 132.2479 square feet.

=================================================

Explanation:

If Carter decides to go for a circle, then 88 is the circumference, which is the distance around the circle (aka perimeter of the circle).

Use this to find the radius needed

C = 2*pi*r

r = C/(2pi)

r = 88/(2pi)

r = 44/pi

I'll leave it in exact form rather than approximate it.

Once we know the radius, we can find the area of the circle.

A = pi*r^2

A = pi(44/pi)^2

A = pi*(1936/(pi^2))

A = 1936/pi

A = 616.247939651819 approximately

I used my calculator's stored version of pi to compute the area in the final step.

We'll be comparing this number later, so hold onto it for now.

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

If Carter instead decides for a square, then 88 is the perimeter since it's the amount of fencing he has to work with.

Divide it into 4 pieces to find the length of each side of the square (all sides are equal in a square)

88/4 = 22

Each side is 22 feet

The area of this square is (22)^2 = 22*22 = 484 square feet

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

Summary:

  • If Carter goes for a circular enclosure, then he gets roughly 616.2479 square feet.
  • The square enclosure only gets him exactly 484 square feet.

The circle wins in terms of larger area.

The difference being roughly 616.2479  - 484 = 132.2479 square feet.

Answer:

\huge \boxed{ \boxed{z = 3}}

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>
  • equation
  • PEMDAS
<h3>let's solve:</h3>
  1. \sf simplify \: substraction :  \\  \frac{3}{ \frac{z - 2}{z} }  = 3z
  2. \sf simplify \: complex \: fractio n : \\  \frac{3z}{z - 2}  = 3z
  3. \sf cross \: multiplication :  \\ 3z = 3z(z - 2)
  4. \sf divide \: both \: sides \: by \:  3z :  \\  \frac{3z}{3z} =   \frac{3z(z - 2)}{3z} \\ 1 = z - 2
  5. \sf add \: 2 \: to \: bot h  \: sides :  \\  z - 2 +  2 = 1 + 2 \\ \therefore \: z = 3

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 3x + 1

f(-2/3) is x = -2/3

<u>Step 2: Evaluate</u>

  1. Substitute:                    f(-2/3) = 3(-2/3) + 1
  2. Multiply:                        f(-2/3) = -2 + 1
  3. Add:                              f(-2/3) = -1
