Answers

Answer 1

9514 1404 393

Answer:

  608 cm²

Step-by-step explanation:

The central rectangle is 10+12+10 = 32 cm high and 16 cm wide. Its area is ...

  A = LW = (32 cm)(16 cm) = 512 cm²

Each of the two triangles on the side have an area of ...

  A = 1/2bh = (1/2)(12 cm)(8 cm) = 48 cm²

There are two triangles and one rectangle, so the total surface area is ...

  total area = rectangle area + 2 · triangle area

  total area = 512 cm² +2(48 cm²) = 608 cm²

Step-by-step explanation:

[tex] si = p \times \frac{r}{100} \times t[/tex]

[tex]si = 40 \times \frac{12}{100} \times \frac{5}{2}[/tex]

[tex]si = \frac{40 \times 12 \times 5}{100 \times 2} [/tex]

[tex]si = \frac{4 \times 12 \times 5}{10 \times 2} [/tex]

[tex]si = \frac{4 \times 12 }{5\times 2} [/tex]

[tex]si = \frac{2 \times 12}{5} [/tex]

[tex]si = \frac{24}{5} [/tex]

[tex]si = 4.8[/tex]

The price of the original shirt is $45, it is reduced to $32.50. Calculate the percentage decrease. Show your workings.

Answers

Answer:

The percent decrease in the price of shirt is 27.78%

Step-by-step explanation:

The percent decrease is the decrease in the price of a product or good.

Given

Original Price = $45

Decreased price = $32.50

Percentage decrease is calculated by using the formula

[tex]Percentage\ decrease = \frac{decrease}{Original\ price} *100\\[/tex]

And the decrease is calculated as:

[tex]Decrease = Original\ price - Reduced\ price[/tex]

So,

[tex]Decrease = 45-32.50 = 12.5[/tex]

Putting the values in the formula for percent decrease

[tex]Percent\ decrease = \frac{12.50}{45} *100\\=0.2777..*100\\= 27.77..[/tex]

Rounding off to nearest hundredth: 27.78%

Hence

The percent decrease in the price of shirt is 27.78%
