Well, then I'm guessing you're only feeding 90 of them since 10 of the dogs are sleeping. If so, then set up a proportion:

\frac{number of dogs}{amount of food}

\frac{100}{10.3}

A proportion is a two fractions set equal to eachother. So, the second fraction will be the number of dogs over x. X will be the amount of food the dogs will get.

\frac{90}{x}

Set the two equations equal to eachother

\frac{100}{10.3} =  \frac{90}{x}

To solve a proportion, cross multiply

100 x X = 100x

90 x 10.3 = 927

100x = 927

Divide 100

x = 9.27

So, the dogs will receive 9.27 of food

Mama L [17]

Answer:

$91.75

Step-by-step explanation:

Jessica is paid:

  • $0.45 per basket for the first 100 baskets picked;
  • $0.50 per basket for all baskets over 100 picked.

1st day:

Jessica picked 65 baskets of oranges (less than 100)

Jessica is paid 65\cdot \$0.45=\$29.25

2nd day:

Jessica picked 135 baskets of oranges (35 more than 100)

Jessica is paid 100\cdot \$0.45+35\cdot \$0.50=\$45+\$17.50=\$62.50

Altogether Jessica is paid

\$29.25+\$62.50=\$91.75

When solving an ______, use inverse operations to undo the operations.
s2008m [1.1K]

Answer:

equation

Step-by-step explanation:

Inverse operations are used to solve simple algebraic equations to more difficult equations that involve exponents, logarithms, and trigonometry. Mathematically, inverse operations are opposite operations. Addition is the opposite of subtraction; division is the opposite of multiplication, and so on.
