Answer:

Hi, I believe the volume of the rock would be 10 mL.

If the beaker originally had 20 mL of water and then the rock turned it to 30 mL, subtract 20 from 30 and you get 10mL

Hope this helps!!!

The volume of the rock is 10 mL as per the concept of subtraction.

To find the volume of the rock, we can use the principle of displacement. When the rock is placed in the beaker, it displaces a certain volume of water equal to its own volume.

The increase in water level from 20 mL to 30 mL represents the volume of the rock.

The volume of the rock = Final volume of water - Initial volume of water

Volume of the rock = 30 mL - 20 mL = 10 mL

Therefore, the volume of the rock is 10 mL. The rock occupies an additional 10 mL of space in the beaker when submerged in the water.

This principle of displacement is based on the fact that the total volume of water and the rock combined remains the same as the initial volume of water in the beaker. By measuring the difference in water levels before and after adding the rock, we can determine the volume of the rock.

Answer:

31 students

Step-by-step explanation:

The constant in the equation is $120 because it is the price the group paid to see the game

The variable is $7 because it depends on how many kids decide to eat snacks (s)

$337 is the total

120 + 7s = 337

Solve the equation:

7s=217

s=31

Using the probability concept, it is found that there is a [tex]\frac{1}{55}[/tex] probability that Luella will pull out a Reese's  Cup, eat it, and then pull out another Reese's Cup.

A probability is the number of desired outcomes divided by the number of total outcomes.

The probability of both events is the multiplication of the probabilities of each event, thus:

[tex]p = \frac{2}{11} \times \frac{1}{10} = \frac{2}{110} = \frac{1}{55}[/tex]

[tex]\frac{1}{55}[/tex] probability that Luella will pull out a Reese's  Cup, eat it, and then pull out another Reese's Cup.

Answer:Y = 3x2+ 4

When equation is in the form of y = Ax2 + Bx + C, it is in standard form.

A = 3, B = 0

Since A is positive, the graph opens upward.

Vertex is the lowest point on the graph.

The x coordinate of the vertex occurs at -B/2A

X =-B/2A = -0/2(3) = 0

To find the y-coordinate, we substitute 0 and solve for y

Y = 3(0)2 + 4 = 4

The vertex is at (0,4) ... the lowest point on the graph

From here, you can construct a table of values for x, and solve for y to obtain points on the graph.

Good x values to pick are -2, -1, 1, and 2

The domain is all the x-values for which the function is defined, The function is defined for all real values of x.

The domain is all real numbers. { x | x is a real number }

The range is all the y values obtained from input of the x-values.

The smallest y value is 4, the largest is positive infinity.

The range is all real numbers ≥ 4. { y | y ≥ 4 }

Hey I got you!!

Step-by-step explanation:

Main points made:

* 3/4 teaspoon for every 2 cups of milk

* Sally wants to know how many teaspoons are required for 3 cups of milk

In this situation I divided 3/4 by 2, which got me 0.375. Then I converted 3/4 to a decimal, which is 0.75. Next, I added 0.375 and 0.75 which equals 1.125. From there I converted 1.125 to a fraction.

My final answer was 9/8 or 1 1/8. Hope this helps! :)

Hello! The additive inverse of -2/5 is 2/5.

if you add -2/5+2/5, you will get 0, so these two numbers are opposites and additive inverses.

Answer:

{x,y} = {2,-2}

Step-by-step explanation:

System of Linear Equations entered :

  [1]    7x + 3y = 8

  [2]    3x - 4y = 14

Graphic Representation of the Equations :

   3y + 7x = 8        -4y + 3x = 14  

Solve by Substitution :

// Solve equation [2] for the variable  x  

 [2]    3x = 4y + 14

 [2]    x = 4y/3 + 14/3

// Plug this in for variable  x  in equation [1]

  [1]    7•(4y/3+14/3) + 3y = 8

  [1]    37y/3 = -74/3

  [1]    37y = -74

// Solve equation [1] for the variable  y  

  [1]    37y = - 74  

  [1]    y = - 2  

// By now we know this much :

   x = 4y/3+14/3

   y = -2

// Use the  y  value to solve for  x  

  x = (4/3)(-2)+14/3 = 2

Solution :

{x,y} = {2,-2}

Gabriel has 4 partners.

When you take the 4 and multiply it by 4, you get 16 where you'd take half of the 16 and add it to it. So you'd have 16 + 8 where it equals 24 and then add the original 4 and you get 28.

Answer:

Question about the triangle, what type of triangle is it?

Step-by-step explanation:

Answer:

We start off with 21 as the first term. So a1 = 21

The common difference is d = -3 because we subtract 3 each time to get from one term to the other (eg: 21 to 18 is minus 3)

The nth term of an arithmetic sequence is found by using this formula

an = a1 + d(n-1)

let's plug in the values we have so far to get

an = 21 + (-3)(n-1)

an = 21 - 3(n-1)

an = 21-3n+3

an = -3n+24

Why do this? Well it's helpful so we can find any term in the formula we want. In this case, we want the 40th term. So just plug in n = 40 from here and you're done

an = -3n+24

a40 = -3*40+24

a40 = -96

pointing you to the answer of choice B) -96

Answer:

A (0,0)

Step-by-step explanation:

When a function intersects the y-axis then the point of intersection is called y-intercept of the function,

Also, for y-intercept x = 0.

That is, if f(x) is the function then its y-intercept is (0, f(0) )

By the given table for x = 0, f(x) = 0

Hence, the y-intercept of the given function is (0,0),

Option A is correct.
