A. A newborn red panda weighs 100 grams. A

77julia77 [94]

Answer:

$y=100\cdot (1.07)^d$

Step-by-step explanation:

Find the expression to represent how much you would expect a cub to weigh $d$ days after it's born as exponential growth function $y=a\cdot b^d,$ where $a$ is the initial panda's weight and $b$ is the rate of growth.

A newborn red panda weighs 100 grams, then $a=100.$

A healthy cub gains about 7% of its newborn weight per day, then

$b=1+0.07=1.07$

Hence,

$y=100\cdot (1.07)^d$

The perimeter of a square is equal to four times the length of a side. Write the direct v variation equation that represents the

sveticcg [70]

Answer: $y=4x$

Step-by-step explanation:

A direct variation equation has the form:

$y=kx$

Where k is a constant.

By definition, we know that the perimeter of the square is the sum of the lengths of its sides or, as all the sides are equal, you can multiply the lenght of any side by 4.

Then, knowing that y is the dependent value and x the independent value and the constant k=4, you can write the following direct variation equation that represents the situation.

$y=4x$

A party mix is made by adding nuts that sell for $2.50 per kg to a cereal mixture that sells for $1 per kg. How much of each sho

Sergio039 [100]

Answer:

44kg of cereal, 16kg of nuts

Step-by-step explanation:

Step 1. We work out how much the party mix would cost if all of it was nuts.

$2.50 x 60kg = $150

Step 2. We work out how much we want the party mix to cost if it had the correct ratio of nuts and cereal.

$1.40 x 60kg = $84

Step 3. We work out the difference between the two above numbers.

$150 - $84 =$66

Step 4. We work out the difference between the nut mix and the cereal mix.

$2.50 - $1 = $1.50

Step 5. We divide the answer to step 3 ($66) by the difference between the nut mix and cereal mix.

$66 ÷ $1.50 = 44

Step 6. The answer to step 5 is the mass of the cereal mix. We then minus 44kg from the total mix mass of 60kg to get the mass of the nut mix.

60kg - 44kg = 16kg

Step 7. We double check.

44kg of cereal = $44 16kg of nuts = $40 $44 + $40 = $84

$84 ÷ 60kg = $1.4 per kg

Hope this helped!
