Talia bought a home for her pet turtle the rectangular tank is 3 feet long. 1 foot wide and 2 feet high. What is the volume?

Answers

Answer:

Volume of rectangular tank = 6 cubic feet

Step-by-step explanation:

Length of the rectangular tank = 3 feet

Width of the tank = 1 feet

And height of the rectangular tank = 2 feet

Since, tank is in the shape of a cuboid,

Volume of a cuboid = Length × Width × height

                                 = 3 × 1 × 2

                                 = 6 cubic feet

Therefore, volume of the rectangular tank will be 6 cubic feet.

find the size of angle q if it is five times it's supplement​

Answers

Answer:

q = 150

Step-by-step explanation:

Supplementary angles are angles that form a straight line and have a sum of 180 degrees, e.g. 120 and 60. If its supplement is thirty, and angle q is five times its supplement, it's 150. We know this is correct because 150 + 30 = 180, which is what we need for a supplementary angle.

Acellus Find the value of x. Round to the nearest tenth. 33° 6 x = [?] PLEASE HELP DONT PUT RANDOM STUFF GETTING REPORTED

Answers

Answer:

3.27

Step-by-step explanation:

Let us assume that the values are the side of a right triangle where;

Hypotenuse = 6 (longest)

Angle of elevation = 33 degrees

Required

x = opposite side

Using the trig identity

Sin theta = opp/hyp

Sin 33 = x/6

x = 6sin33

x = 6(0.5446)

x = 3.27

Hence the value of x is 3.27

Note that the values of the sides are assumed.

The results of a study exhibit response bias. Select the statement that best describes the bias in the study.

There were not enough subjects who chose to respond to a survey that was sent as part of the study.

The interviewer for the study was the boss of the subjects.

The interviewer for the study did not record the responses of the subjects accurately.

Answer:

"The interviewer for the study did not record the responses of the subjects accurately." I believe this is most pertinent. B, or the boss of the subjects, could have been an answer, but if all members associated in the study exhibit the similar level of response bias based upon superior employers, then the study remains somewhat accurate, but C, or inaccurate record of responses, would remain biased entirely.

D. (5y - 5x)^6

Answers

Given:

The statement is "Five times the difference of the cube of y and the square of x".

To find:

The algebraic expression for the given statement.

Solution:

We know that,

Cube = Power 3

Square = Power 2

Difference = Minus (-)

Times = Multiplication (×)

Now,

Cube of y = [tex]y^3[/tex]

Square of x = [tex]x^2[/tex]

Difference of the cube of y and the square of x = [tex]y^3-x^2[/tex]

Five times the difference of the cube of y and the square of x is:

Required expression = [tex]5(y^3-x^2)[/tex]

Therefore, the correct option is C. The required algebraic expression for the given statement is [tex]5(y^3-x^2)[/tex].
