D is directly proportional to t2 When t = 4, D = 8 Find the positive value of t when D = 50

Answers

Answer 1

Answer: either 46 or 25 is your answer

Step-by-step explanation: Brainliest pls

Answer 2

Answer:

t = 10

Step-by-step explanation:

Proportions

D is directly proportional to t squared. This can be written as:

[tex]D = kt^2[/tex]

Where k is the proportionality constant. It can be calculated by substituting the given condition in the formula, when t=4, D=8:

[tex]8 = k4^2=16k[/tex]

Solving for k:

[tex]k=\frac{8}{16}=\frac{1}{2}[/tex]

Thus, the proportional relationship is:

[tex]\displaystyle D = \frac{1}{2}t^2[/tex]

When D=50, the value of t can be found by solving for t:

[tex]\displaystyle 50 = \frac{1}{2}t^2[/tex]

Multiplying by 2:

[tex]t^2=100[/tex]

Taking the square root:

[tex]t=\sqrt{100}[/tex]

The positive value of t is:

t = 10

Answers

                                                      Question 1)

Given

The expression is 5xy

To determine

Find the value of 5xy if x = 2 and y = 3

5xy

substitute x = 2 and y = 3

5xy = 5(2)(3)

      = 5(6)

      = 30

Therefore, the value of 5xy = 30 if x = 2 and y = 3.

Note: your remaining questions are not mentioned. But, the procedure may remain the same. Hopefully, your concept will be cleared anyway.

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]

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

Paul is filling a kiddy pool that can hold up to 25 gallons of water. The water hose fills the tub at a constant rate. When Paul checks the pool, it contains 5 gallons of water. Three minutes later, the pool contains 7.4 gallons of water. At what rate does the pool fill up with water?

Answers

Answer:

0.8 gallons per second

Step-by-step explanation:

Given that :

Filling occurs at a constant rate ;

Change in gallon of water in pool within a 3 seconds time interval ;

Assume :

At t = 0 ; gallons = 5

At t = 3 ; gallons = 7.4

Chanhe in gallons with time.;

(7.4 - 5) / (3 - 0)

2.4 / 3

= 0.8 gallons per second

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

And

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

On the contrary, it is the case of convicting a citizen as a punishment for not submitting to imprisonment in aconcentration camp, based on his ancestry, and solely because of his ancestry, without evidence or inquiry concerning hisloyalty and gooddisposition towards the United States. If this be a correct statement of the facts disclosed by this record, and facts of which we take judicialnotice, I need hardly labor the conclusion that constitutional rights have been violated.The Government's argument, and the opinion of the court, in my judgment, erroneously divide that which is single and indivisible, and thusmake the case appear as if the petitioner violated a Military Order, sanctioned by Act of Congress, which excluded him from his home by refusingvoluntarily to leave, and so knowingly and intentionally defying the order and the Act of Congress.The petitioner, a resident of San Leandro, Alameda County, California, is a native of the United States of Japanese ancestry who, according to theuncontradicted evidence, is a loyal citizen of the nation.
