Enter a numerical expression that represents sixty divided by the difference of t cubed and nineteen.

Answers

Answer: 60/ t^3-19. In these expressions, difference=subtraction. So, when it asks you to find the difference between two number/variables. You subtract them. Hope that helped!

The expression that represents sixty divided by the difference of t cubed and nineteen will be 60 / (t³ - 19).

What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The cube of the t is written as t³. Then the difference between the expression t³ and the numerical number 19 will be given as,

⇒ t³ - 19

Then the expression that represents sixty divided by the difference of t cubed and nineteen will be given as,

⇒ 60 / (t³ - 19)

at its peak in online shopping site was selling about 420 items per second at this rate how many items would it sell in 30 mins( 1800 seconds?)​

Answers

Answer:.

Step-by-step explanation:

The online shopping site would sell; 756000 items in 30 minutes

What is the fundamental principle of multiplication?

Multiplication is the mathematical operation that is used to determine the product of two or more numbers.

Given that the online site would sell 420 items in a second

To determine the number of items it would sell in 30 minutes first of all convert minutes into seconds.

To convert minutes into seconds, we will just multiply minutes with 60.

WE know that one minute is equal to 60 seconds.

Therefore 30 minutes = 30 x 60 seconds

30 minutes = 1800 seconds

Thus the number of items sold in 30 minutes be x.

now,

420 x 1800 = x

x= 756000

Hence, It is found that the site will sell 756000 items in 30 minutes.

A submarine cruised below the surface of the water. During a training exercise, it made 6 dives, each time descending 35 feet more. Then it rose 122 feet. What is the change in the submarine’s position?

Answers

Answer:

68 feet

Step-by-step explanation:

A submarine cruised  below the surface of the water

During training exercise, each time descending= 45 feet

Number of dives= 4

Total distance he descended= 45×4 feet

Total distance he descended= 180 feet

Then, it rose by= 112 feet

Now , the distance he is at below the surface if water= 180- 112

The distance he is at below the surface if water= 68 feet

Now, he is at 68 feet below the surface of the Earth

Hence, the correct answer is 68 feet

Rosanne makes 1 1/2 liters of strawberry lemonade. She pours 1/4 of a liter of lemonade into a thermos to take to the park. Her brother drinks 2/5 of the remaining lemonade. How much lemonade does rosanne’s brother drink?

Answers

Answer:

1/2 liters

Step-by-step explanation:

Rosanne makes 1 1/2 liters of strawberry lemonade

She pours 1/4 of the lemonade into a thermos

The quantity left is

= 1 1/2 - 1/4

= 3/2 - 1/4

= 5/4

Her brother drinks 2/5 of the remaining lemonade

Therefore the quantity of lemonade that Rosanne brother drinks can be calculated as follows

= 2/5 × 5/4

=1/2

Hence the quantity of lemonade that Rosanne brother drinks is 1/2 liters

Answer:

1/2 liters

Step-by-step explanation: Rosanne makes 1 1/2 liters of strawberry lemonade

She pours 1/4 of the lemonade into a thermos

The quantity left is

= 1 1/2 - 1/4

= 3/2 - 1/4

= 5/4

Her brother drinks 2/5 of the remaining lemonade

Therefore the quantity of lemonade that Rosanne brother drinks can be calculated as follows

= 2/5 × 5/4

=1/2


Angela is playing with red and black marbles. The number of red marbles she has is three
more than twice the number of black marbles she has. She has 42 marbles in all. Which
system of equations can be used to find the number of red marbles, R, and black marbles, B?o

Answers

Answer:

We will need two equations, one that adds up to the total number of marbles, and the other which writes one type of marbles in terms of the other.

For the first equation we know that:

[tex]r + b = 42[/tex]

For the second we are told that "The number of red marbles she has is three  more than twice the number of black marbles she has."

So we simply translate this into an equation being:

[tex]r = 2b + 3[/tex]

If the point (-2, -4) was reflected in the x-axis and then translates five units right and seven units down, what would be the coordinates of its image?

Answers

Answer:

(3,-3)

Step-by-step explanation:

First, plot the ordered pair (-2,-4). Since you're reflecting the ordered pair across the x-axis, change the -4 to a positive 4. Your new ordered pair should be (-2,4). The order pair when reflected across the x-axis is changing the positive or negative of the y value but keeping the x value the same(simple definition). Afterward, move/translate that reflected ordered pair across 5 units to the right which is (3,4). The last step is to translate that order pair 7 units down which will then give you your answer of (3, -3). I hope this helps you, I tried explaining it the best I could!

The coordinates of the image of the point (-2, -4) will be (3, -3).

What is translation of graph?

Function translation takes a function (and its graph) and, by adding and subtraction, moves the graph around the plane without changing its shape.

Given is a point (-2, -4) which is reflected along the x - axis.

Now, when a point is reflected across the x - axis, then its final coordinates will change according to the rule -

(x, y)  ↔  (x, -y)

The given coordinates are (-2, -4) which on being reflected across the x - axis will  become (-2, 4).

Now, it is given that after reflection, it is translated five units right and seven units down. We can define it by the rule -

(x, y) ↔ (x + 5, y - 7)

So the new coordinates of the image will be -

(-2, 4) ↔ (-2 + 5, 4 - 7) or (3, -3)

Therefore, the coordinates of the image of the point (-2, -4) will be (3, -3).
