The number of dogs in the animal shelter which comprise of cats, dogs, and rabbits is 84 dogs.

<h3>Equation</h3>

Total animals = 5 × 47

= 235

  • Number of rabbits = 1/2(d + 20) - 5
  • Number of cats = d + 20
  • Number of dogs = d

235 = d + (d + 20) + 1/2(d + 20) - 5

235 = d + d + 20 + 1/2d + 10 - 5

235 = 2 1/2d + 25

235 - 25 = 2 1/2d

210 = 2 1/2d

d = 210 ÷ 2 1/2

d = 210 ÷ 5/2

= 210 × 2/5

= 420/5

d = 84 dogs

4vir4ik [10]

Answer:

number of people who will purchase next month = 250

the number of people who will purchase in 2 month = 325

Step-by-step explanation:

Data provided in the question:

people who purchase the plant's product during any month will not purchase it the next month = 30%

therefore, people who purchase the plant's product during any month will purchase next month = 70%

people who do not purchase the product during any month will purchase it the next month = 20%

Total number of people = 1000

Number of people who purchased this month = 100

Number of people who did not purchase = 1000 - 100 = 900

therefore,

the number of people who will purchase next month

= 70% of 100 + 20% of 900

= 0.70 × 100 + 0.20 × 900

= 70 + 180

= 250

now,

the number of people who will purchase in 2 month

= 70% of (number of people who will purchase next month) + 20% of (number of people who did not purchase next month)

= 70% of 250 + 20% of (1000 - 250)

= 0.70 × 250 + 0.20 × 750

= 175 + 150

= 325

Simplify (-2/5) divided by (8/9) times (2/9) divided by (-1/3) explain and show all steps
spayn [35]

Simplification of (-2/5) divided by (8/9) times (2/9) divided by (-1/3) is 0.3

<em><u>Solution:</u></em>

Given that,

Simplify (-2/5) divided by (8/9) times (2/9) divided by (-1/3)

Here "times" represent multiplication

<em><u>The above sentence can be written mathematically as:</u></em>

\frac{-2}{5} \div \frac{8}{9} \times \frac{2}{9} \div \frac{-1}{3}

Convert the problem to multiplication by changing the division sign to multiplication. When we change division sign to multiplication, the fraction becomes reciprocal

\rightarrow \frac{-2}{5} \times \frac{9}{8} \times \frac{2}{9} \times \frac{3}{-1}

Cancelling the common terms in numerator and denominator,

\rightarrow \frac{-2}{5} \times \frac{1}{8} \times \frac{2}{1} \times \frac{3}{-1}

Multiplying terms in numerator and denominator,

\rightarrow \frac{-12}{-40}

Negative sign in numerator and denominator cancels each other

\rightarrow \frac{-12}{-40} = \frac{12}{40}

Reducing to lowest terms we get,

\rightarrow \frac{12}{40} = \frac{3}{10}

In decimal form we get,

\rightarrow \frac{3}{10} = 0.3

Thus solution to given expression is 0.3
