Answer:

Total amount earn = $31.98

Step-by-step explanation:

Given:

Cost of paper = $1.41

Cost of aluminium = $1.53

Cost of plastic = $0.33

Amount of paper = 5 pound

Amount of aluminium = 15 pound

Amount of plastic = 6 pound

Find:

Total amount earn

Computation:

Total amount earn = ($1.41)(5) + ($0.33)(6) + ($1.53)(15)

Total amount earn = $7.05 + $1.98 + $22.95

Total amount earn = $31.98

<h2><u>\bold\color{plum}\tt \: Answer  \: \:  1 :</u></h2>

Diameter = 4 cm

Radius = Diameter/2 = 2 cm

Area of circle :

= \pi{r}^{2}

= 3.14 \times 2 \times 2

= 3.14 \times 4

= 12.56 \:   {cm}^{2}

Circumference of circle :

= 2\pi r

= 2 \times 3.14 \times 2

= 12.56 \: \:   {cm}^{2}

<h2>Therefore, </h2><h3>Diameter = 4 cm</h3><h3>Radius = 2 cm</h3><h3>Area = 12.56 cm²</h3><h3>Circumference = 12.56 cm</h3>

<h2><u>\bold{\color{plum}\tt \: Answer  \: \:  2 :}</u></h2>

Circumference = 15 feet (given)

Radius :

= 2\pi  r

= 2 \times  \frac{22}{7}  \times r = 15

=  \frac{44}{7}  \times r = 15

= 44r = 15 \times 7

= 44r = 105

= r =  \frac{105}{44}

= r = 2.38 \: feet

Diameter = r×2 = 2.38 × 2 = 4.76 feet

Area :

= \pi  {r}^{2}

= 3.14 \times 2.38 \times 2.38

= 17.78 \:  {ft}^{2}

<h2>Therefore, </h2><h3>Diameter = 4.76 feet</h3><h3>Radius = 2.38 feet</h3><h3>Area = 17.78 ft²</h3><h3>Circumference = 15 feet</h3>

<h2><u>\color{plum}\tt \: Answer  \: \:  3 :</u></h2>

Diameter = 2 cm (given)

Radius = D/2 = 2/2 = 1 cm

Circumference :

= 2 \pi r

= 2 \times 3.14 \times 1

= 6.28 \: feet

Area :

= \pi  {r}^{2}

= 3.14 \times 1 \times 1

= 3.14 \:  {ft}^{2}

<h2>Therefore, </h2><h3>Diameter = 2 cm</h3><h3>Radius = 1 cm </h3><h3>Area = 3.14 ft²</h3><h3>Circumference = 6.28 feet</h3><h2 /><h2><u>\color{plum}\tt \: Answer  \: \:  4 :</u></h2>

Radius = 4.3 mm

Diameter = r×2 = 4.3 × 2 = 8.6 mm

Circumference :

= 2\pi r

= 2 \times 3.14 \times 4.3

= 27 \: mm

Area :

= \pi  {r}^{2}

= 3.14 \times 4.3 \times 4.3

= 3.14 \times 18.49

= 58.05 \:  {mm}^{2}

<h2>Therefore, </h2><h3>Diameter = 8.6 mm</h3><h3>Radius = 4.3 mm</h3><h3>Area = 58.95 mm²</h3><h3>Circumference = 27 mm</h3>

How many solutions does the equation have?
SSSSS [86.1K]
Let's solve and find out.

4(2n - 4) + 3 = 8n - 19
8n - 16 + 3 = 8n - 19
8n - 13 = 8n - 19
-13 = -19

-13 and -19 are not equal, so the equation has no solutions.

A. 0

What is 4 Over 25 divided by 15 over 16
Ket [755]
The answer is .17 if ur doing it in a calculator. if ur doing it by hand u do 4/25, but u cant divide fractions. so, for the second set of numbers u would change it to 16/15. then do 4/25 times 15/16 and u get 64/375, which is equivalent to .17 :)
