Answer:

Step-by-step explanation:

#7- Irrational; The adding of one 8 every time it well, gets to an 8, changes the pattern. For a decimal to be rational, it has to be steady, set from the beginning, and has to keep that pattern the whole time.


#9- C and E;

C. Pi (3.14…) is a continuous number that goes on forever and has no pattern to it, thus making it irrational.

E. Is one of those decimals that just decide to be different and difficult and have no repetition of patterns and goes on forever


#10- Just the square root of 15; Square root of 196 is 14; 5/9 is 0.5repeating… which I beliiieeeeve is rational?; and 7.27repeating have the same ongoing pattern


#11- 26, -3/2, 0, 9;

26 is a whole number; -3/2 would be -1.5 as a decimal, no extra numbers; 0 just… well… 0, so rational; and 9 is a whole number.


#12- No, it is irrational.; Same explanation as number 7, but instead of 8’s and 7’s it’s with 5’s and 6’s.

No need for a second answer, I agree with what this guy says^^^^

Q1. If ∛5x+10=5, Find x

Answers

Answer: x=-25

Step-by-step explanation:

Concept to know:

When given a number that is cubic root, in order to solve the equation/function, you need to cube numbers on both sides.

Solve:

Given

∛5x+10=5

Subtract 10 on both sides

∛5x+10-10=5-10

∛5x=-5

Cube numbers on both sides

5x=-125

x=-25

Answer:

x = -25

Step-by-step explanation:

If ∛5x+10=5, Find x

∛5x = 5 - 10

∛5x = -5

take both sides of equation to the power of 3

5x = -125

x = -125/5

x = -25

A waitress sold 15 ribeye steak dinners and 28 grilled salmon dinners, totaling $551.97 on a particular day. Another day she sold 24 ribeye steak dinners and 14 grilled salmon dinners, totaling $581.91. How much did each type of dinner cost?

Answers

Answer:

Ribeye (ea) = $18.54

Salmon (ea) = $9.78

Step-by-step explanation:

x is the price for each ribeye steak

y is the price for each grilled salmon

15x + 28y  = $551.97 (a)

24x + 14y = $581.91 (b) -----(x2)------> 48x + 28y = 1163.82 (c)

Subtract c with a

48x + 28y = 1163.82 (c)

15x + 28y  = $551.97 (a)

===================  -

33x           = 611.85

x = 18.54

Put the value of x into a

15 · 18.54 + 28y = 551.97

278.1 +28y = 551.97

28y = 273.87

y = 9.78

In conclusion, the price of 1 ribeye is $18.54, and the price of 1 salmon is $9.78.

Ribeye is 18.54 and salmon is 9.78

Answer:

A = plane

B = whale

C = sunken ship

Step-by-step explanation:

The given vertical number line is modelling the positions of objects and animals in relation to sea level.

Sea level is the average height of the surface of the world's oceans, which we use as a reference point to measure the elevation and depth of land and water features on Earth.

From inspection of the given number line:

Position A is above sea level.Position B is just below sea level.Position C is the furthest below sea level.

We have been told that a plane is flying at 8,500 feet above sea level. Therefore, as position A is the only position above sea level, A = plane.

We have been told that a sunken ship is resting at 3,000 feet below sea level, and that directly above the ship, a whale is swimming 1,960 feet below sea level. Therefore, the whale is above the ship. As position B is above position C, this means that B = whale and C = sunken ship.

A is plane b is whale c is sunken ship
