How many gallons of water will be in the fish tank after 3 minutes? how can you explain your answer

Answers

The question is incomplete, the complete question is;

If in 0.5 min the tank gets 0.8 gallons of the water then

how many gallons will be in 1 min ?

how many gallons will be in 3 min?

and how long it takes for 40 gallons?

Answer:

1.6 gallons

4.8 gallons

25 mins

Step-by-step explanation:

This question has to do with proportion.

If it takes 0.5 mins for the tank to get 0.8 gallons

in 1 minute the tank will get 0.8 * 1/0.5 = 1.6 gallons

In 3 minutes the tank will get 3 * 1.6 gallons = 4.8 gallons

if it takes 1 min to get 1.6 gallons

it will take x mins to get 40 gallons

x = 1 * 40/1.6 = 25 mins

in a survey, 8 out of 32 students preferred vanilla ice cream if 252 students are surveyed how many should theoretically prefer ice cream

Answers

Answer:

63 people

Step-by-step explanation:

Given parameters:

Number of students survey = 32

Number of those that liked ice-cream = 8

Total population size  = 252

Unknown:

How many people in the population should prefer ice cream  = ?

Solution:

  From the survey;

    8 out of 32 students prefer ice cream;

     8 : 32

     1: 4

This shows that 1 out of 4 students will prefer ice cream

NOw to the total population;

  If out of 4 students, 1 prefers ice-cream;

     Number of students that prefers ice-cream = [tex]\frac{252}{4}[/tex] = 63people

A sphere has a diameter of 24 units. What is its volume in cubic units?
A.576pi cubic units
B.1,728pi cubic units
C.2,304pi cubic units
D 6,912pi cubic units

Pls help!!

Answers

Answer:

C.2,304pi cubic units

Step-by-step explanation:

Volume of the sphere:

V = 4/3πr³

Since d = 24 units,

r = d/2 = 12 units

Then

V = 4/3π(12³) = 2304π

Correct option is C

The angle o represents the phase shift, determined by the initial conditions of the experiment or the position of the weight at t = 0. If the weight is at its maximum positive position (weight is above equilibrium) at t = 0, then o = 0. If the weight is at its maximum negative position (spring is stretched and weight is below equilibrium) at t = 0, then o = pi. If the weight is traveling in the negative direction and passing through equilibrium at t = 0, then o = pi/2. In the response box, describe the initial condition of our experiment; specifically, describe the position of the weight and the direction in which it was traveling.

Answers

Answer

 initially t=0 => c2sin(0)+c1cos(0) => y=0+c1 =>  y=0+5 => y=5

Is 25 x 10 to the power of 0 in scientific​ notation? If​ not, explain. Use pencil and paper. Explain why 10 is used as the base in the second scientific notation factor.

Answers

Answer:

a) Scientific notation is written as a unit digit, that can have other digits after the decimal place, multiplied by 10 to the power of n, where n can be any integer number.

Then 25x10^0 is not scientific notation, because there are two digits at the left of the decimal point.

The scientific notation would be:

2.5x10^1

b) Why is this useful?

Because we divide all our measures in powers of 10.

For example, you know that 1 meter  = 100c

But we can also write this as:

1m = 1.0*10^3 cm.

The use of scientific notation comes useful because we can have a fast read of the dimensions of our measure, and in another hand, is way easier work with the 10 as a base when we solve equations.

Answers

Answer:

D: x+6

Step-by-step explanation:

The factor of the polynomial function f(x) is x + 6

What are factors?

The factors of a polynomial are the quotients and the zeros of the polynomial

The points on the polynomial curve are given as:

(-6,0), (-3,0) and (0,0)

So, we have:

x = -6

x = -3

x = 0

Equate the above equations to 0

x + 6 = 0

x + 3 = 0

x = 0

Hence, the factor of the polynomial is x + 6

A square on a coordinate plane has the points A(0, 0), B(0, 5), C(5, 5) and D(5, 0). If Square ABCD is rotated about the origin 180 degrees clockwise to form Square A'B'C'D', what would be the length of one of the sides? A. 0 units B. 5 units C. 10 units D. 20 units

Answers

Answer:

B. 5 units

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, dilation, rotation or translation.

If a point X(x,y) is rotated about the origin 180 degrees clockwise the new point is at X'(-x, -y).

If the square with vertices at A(0, 0), B(0, 5), C(5, 5) and D(5, 0) is rotated about the origin 180 degrees clockwise the new points are at A'(0, 0), B'(0, -5), C'(-5, -5), D'(-5, 0)

A square has four equal sides. The distance between two points [tex]X(x_1,y_1)\ and\ Y(x_2,y_2)[/tex] is:

[tex]|XY|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
