Meg is packing a shipping conditier.

There is one section of the shipping container that has not yet been packed. The space available is in the shape of rectangular

prism that measures 2 feet by 3 feet by 33 feet.

She will pack as many boxes into the available space as possible. Each box is in the shape of a cube with side length 1 foot.

The space available in the shinning container and one of the boxes are shown below.

Answers

Answer:

[tex]Boxes= 198[/tex]

Step-by-step explanation:

This question has uncleared details towards the end. However, one can deduce that we need to calculate the amount of box the available space can contain.

We have the following given parameters.

Shipping Container

[tex]Dimension: 2ft\ by\ 3ft\ by\ 33ft[/tex]

The box

[tex]Dimension: 1ft\ by\ 1ft\ by\ 1ft[/tex]

First, we calculate the volume of the shipping container.

[tex]V_A = 2ft * 3ft * 33ft[/tex]

[tex]V_A = 198ft^3[/tex]

Next, we calculate the volume of the box.

[tex]V_B = 1ft * 1ft * 1ft[/tex]

[tex]V_B = 1ft^3[/tex]

The number of box is then calculated as:

[tex]Boxes= \frac{V_A}{V_B}[/tex]

[tex]Boxes= \frac{198ft^3}{1ft^3}[/tex]

[tex]Boxes= \frac{198}{1}[/tex]

[tex]Boxes= 198[/tex]

Hence:

198 boxes will occupy the empty space

Step-by-step explanation:

This graph shows conjunction. This means that the two statements of the inequality bare true at the same time. Therefore, it follows that:

x > -2 ("we use greater than" because the empty/unshaded circle indicates that -2 is not included)

And

x ≤ 6 (we use greater than or equal to because the shaded circle indicates 6 is included)

Joining both statements together, we would have:

Determine the value of c that will result in a perfect square trinomial.
w^2+6w+ c =130+c

Answers

Answer:

The value of c that will result in a perfect square trinomial is (3)^2 or 9

The perfect square trinomial is: [tex](w+3)^2=139[/tex]

Step-by-step explanation:

We need to determine the value  of c that will result in a perfect square trinomial.

[tex]w^2+6w+ c =130+c[/tex]

Perfect square trinomial are of form: [tex]a^2+2ab+b^2=(a+b)^2[/tex]

Now, the equation given is:

[tex]w^2+6w+ c =130+c[/tex]

Looking at the term 6w, we can write it as 2(w)(3)

We are given: a = w, 2ab = 2(w)(3) so, b will be: (3)^2

So, we will be adding (3)^2 on both sides

[tex]w^2+6w+ c=130+c\\w^2+2(w)(3)+ (3)^2 =130+(3)^2\\The\:left\:side\:becomes: a^2+2ab+b^2\\We\:can\:write\:it\:as: (a+b)^2\\We\:have\:a=w\: and\: b=3\\(w+3)^2=130+9\\(w+3)^2=139[/tex]

So, The value of c that will result in a perfect square trinomial is (3)^2 or 9

The perfect square trinomial is: [tex](w+3)^2=139[/tex]

The largest species of jellyfish is the​ lion's mane jellyfish. One particular specimen has a diameter of 1.03 meters and tentacles that are 29 meters long. The specimen weighs 164 kilograms and can travel at a speed of 1.38 meters per second.
What is the diameter of the specimen in​ centimeters?

Answers

Answer:

The diameter of the specimen in centimeters is 103 cm.

Step-by-step explanation:

In order to determine the diameter in centimeters of the largest specimen of jellyfish, knowing that said diameter is 1.03 meters, and that 1 meter is equal to 100 centimeters, the following calculation must be performed:

1.03 x 100 = X

103 = X

Therefore, the diameter of the specimen in centimeters is 103 cm.
