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: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 }

Step-by-step explanation:

6x - 5 + 3x - 4 = 180     {Supplementary angles}

6x + 3x - 5 - 4 = 180

Combine like terms

9x - 9 = 180

Add 9 to both sides

9x = 180 + 9

9x = 189

Divide both sides by 9

 x = 189/9

x = 21

Answer:

Step-by-step explanation:

The currency called the U.S dollar can be split into smaller forms or currency value of itself. Examples of these smaller forms are: dimes, nickels, pennies, and quarters.

Tammy has 23 nickels and 12 quarters.

Let's represent the number of:

Nickels = n

Quarters = q

It is important to note that the value of:

1 nickel = $0.05

1 quarter = $0.25

Tammy has 35 coins nickels and quarters. This statement can be represented using an algebraic equation below:

n + q = 35

This can be rewritten as :

n = 35 - q

In all, she has $4.15. This statement can be represented using an algebraic equation below:

0.05n + 0.25q = 4.15

We substitute 35 - q for n in the above equation.

0.05(35 - q) + 0.25q = 4.15

1.75 - 0.05q + 0.25q = 4.15

Collect like terms

- 0.05q + 0.25q = 4.15 - 1.75

0.2q = 2.4

Divide both sides by 0.2

0.2q/0.2 = 2.4/0.2

q = 12

Therefore, the number of quarters Tammy has is 12.

Solving for the number of nickels, we have the equation:

n = 35 - q

n = 35 - 12

n = 23

Therefore, the number of nickels Tammy has is 23.

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.

Answer and Step-by-step explanation:

To figure out the problem, we first need to know what supplementary means. In this question, supplementary (angles) is when two angles are next to each other, and when added together, they add up to 180 degrees.

By looking at the image, we see that angle 1 is next to angles 2 and 5.

Angles 1 and 2 don't look like they will add up to 180 degrees.

Angles 1 and 5 look like they will add up to 180 degrees.

A way to find supplementary angles is by looking at lines that go straight across, with a line intersecting the middle of the line to form the supplementary angles.
