To find the cost per pound you simply divide the amount paid by the amount purchased

For Beef it would be:
$7.20 ÷ 2.0 = $3.60


For Pork it would be:
$8.10 ÷ 2.5 = $3.40


For Chicken it would be:
$9.80 ÷ 3.5 = $2.8

Please help me with my question,Thanks!! (By the way the ratio is 12 to 36)
saul85 [17]
To answer this, you would use the original ratio of 2 to 5 and create an equivalent ratio that includes the 12 tulips. You would get a ratio of 12 to 30. This is not enough daisies.

I then tried 2/5 times 7/7, but it still did not reach the 36 daisies that are there. When you use a factor of 8, you will get 16 tulips to 40 daisies. This works!

You would need to add 4 tulips and 4 daisies to what he already has.

A bucket that weighs 6 lb and a rope of negligible weight are used to draw water from a well that is 80 ft deep. The bucket is f
zaharov [31]

Answer:

3200 ft-lb

Step-by-step explanation:

To answer this question, we need to find the force applied by the rope on the bucket at time t

At t=0, the weight of the bucket is 6+36=42 \mathrm{lb}

After t seconds, the weight of the bucket is 42-0.15 t \mathrm{lb}

Since the acceleration of the bucket is the force on the bucket by the rope is equal to the weight of the bucket.

If the upward direction is positive, the displacement after t seconds is x=1.5 t

Since the well is 80 ft deep, the time to pull out the bucket is \frac{80}{2}=40 \mathrm{~s}

We are now ready to calculate the work done by the rope on the bucket.

Since the displacement and the force are in the same direction, we can write

W=\int_{t=0}^{t=36} F d x

Use x=1.5 t and F=42-0.15 t

W=\int_{0}^{36}(42-0.15 t)(1.5 d t)

=\int_{0}^{36} 63-0.225 t d t

=63 \cdot 36-0.2 \cdot 36^{2}-0=3200 \mathrm{ft} \cdot \mathrm{lb}

=\left[63 t-0.2 t^{2}\right]_{0}^{36}

W=3200 \mathrm{ft} \cdot \mathrm{lb}

A zoo has 60 penguins total. If the Emperor penguins make up 35% of all of the penguins at the zoo, how many Emperor penguins ar
r-ruslan [8.4K]

Answer:

There are 21 emperor penguins at the zoo

Step-by-step explanation:

The total number of penguins in the zoo = 60

The percentage share of emperor penguin in the total population of penguin = 35 %

Number of emperor penguins at the zoo

\frac{35}{100} * 60

0.35 * 60

= 21

There are 21 emperor penguins at the zoo
