  2.4 g/cm^3

Step-by-step explanation:

Density is the ratio of mass to volume (as the units g/cm^3 tell you). If you cut the marble in half, each piece will have half the mass and half the volume, so the density remains unchanged. It will still be ...

Answer:

y = 3 x − 3

Step-by-step explanation:

The equation for slope-intercept form is as follows:

To find  c , substitute  x = 3 ,  y= 6  and  m = 3  into the equation,6=3 (3 ) + c c= 6 − 9 c = − 3  Since we found  m = 3  and  c= − 3 , we can form the equation,  = 3 x− 3

Answer:

y=120

Step-by-step explanation:

y=80 when ×=8 because 8 × 10 = 80

therefore multiplying 12 by 10 gives us 120

Answer:

y=120 when x=12

Step-by-step explanation:

From the pattern I noticed that y is pretty much 10 times the value of x. So when x equals 12, y will equal 120.

Answer:

[tex]560v^{10}u^{4}[/tex]

Step-by-step explanation:

Simplify the expression.

Use the distributive property (of which the FOIL method is a special case):

(a - b) (a² + ab + b²)

= (a - b) a² + (a - b) ab + (a - b) b²

= (a³ - a²b) + (a²b - ab²) + (ab² - b³)

= a³ - b³

Alternatively, you can distribute the quadratic expression over each term in a - b :

(a - b) (a² + ab + b²)

= a (a² + ab + b²) - b (a² + ab + b²)

= (a³ + a²b + ab²) - (a²b + ab² + b³)

= a³ - b³

Answer:

24 units squared

Step-by-step explanation:

you have to first find the area of the base, which is 4 * 4 which is 16. then, to find the area of the triangles, you multiply the base by height, 4 * 3 = 12, and since we have 4 triangles, and one triangle would be (1/2) * base * height, you can multiply this result by 2, which would equal 24

Answer:

The answer is option A y = −1.988x + 43.293

Step-by-step explanation:

I just took the test

The equation of the least squares regression line for the data set will be;

y = -1.988x + 43.293

Option A is true.

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

Given that;

The table of data set is shown in figure.

Now, Let hours represent by x.

And, Tickets sold represent by y.

So, By the equation;

y = -1.988x + 43.293

Substitute x = 11;

y = -1.988 × 11 + 43.293

y = - 21.868 + 43.293

y = 21.62

y = 22

And, For x = 9;

y = -1.988 × 9 + 43.293

y = -17.892 + 43.293

y = 25.4

y = 24

Thus, Equation y = -1.988x + 43.293 shows the least-squares regression line for the data set.

So, The equation of the least squares regression line for the data set will be;

y = -1.988x + 43.293

Step-by-step explanation:

first you want to divide the ounces of liquid soap we have by the ounce bottles we have (58.5 / 4.5 = 13 )

so now we know we have 13 bottles of liquid soap

then you want to multiply the 13 bottles of soap by how much they sell each bottle for ( 13 x 5.50 = 71.50 )

the answer: the students would earn $71.50 if they sell all the bottles of liquid soap

Answer:the answer is (-2,1)

Step-by-step explanation:

When rotating a point 90 degrees counterwise about the origin point (x,y) becomes (-y,x). So basically switch x and y and make y negative when rotating 90 degrees counterclockwise about the origin.

If the triangle is rotated counterclockwise 90 degrees about the origin, the angle C = (1, 2) will become C = (-1, 2).

It is a two dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

Triangle ABC is located on a coordinate plane.

Angle C is at (1, 2).

This means that,

Angle C = (1, 2) is in the I Quadrant.

We have four Quadrant:

Quadrant I - The coordinates are in the form of (x, y)

Quadrant II - The coordinates are in the form of (x, -y)

Quadrant III - The coordinates are in the form of (-x, -y)

Quadrant IV - The coordinates are in the form of (-x, y)

If we rotate C = (1, 2) counterclockwise 90 degrees about the origin, the angle C will be in the IV quadrant.

So,

C = (1, 2) will become C = (-1, 2)

Thus,

If the triangle is rotated counterclockwise 90 degrees about the origin, the angle C = (1, 2) will become C = (-1, 2).

Answer:

I am not completely sure I think it is A im not positive but I think

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

On the left, we have 7 -Xs and 7 1s. So, the left can be represented by the expression:

[tex]-7x+7[/tex]

On the right, we have 5 (positive) Xs and 16 1s. So, the right can be represented by the expression:

[tex]5x+16[/tex]

They are equal to each other. So:

[tex]-7x+7=5x+16[/tex]

Solve for x. Add 7x to both sides:

[tex]7=12x+16[/tex]

Subtract 16 from both sides:

[tex]-9=12x[/tex]

Divide both sides by 12:

[tex]x=-9/12[/tex]

Reduce:

[tex]x=-3/4[/tex]

So, our answer is C.

Step-by-step explanation:

27-30: The factor pairs can be found by looking at the unique subsets of the set of prime factors. The product of the elements of each subset will be a divisor. The "empty" set can be considered to contain 1. When divisors are listed in numerical order, the factor pairs can be found by pairing factors from each end of the list, working toward the center. If the number is a perfect square, there will be an odd number of divisors, and the center number will be used twice

Examples:

  18 = 2×3×3 (prime factorization).

Subsets of these factors are  {}, {3}, {3}, {3,3}, {2}, {2,3}, {2,3}, {2,3,3}. Then the divisors are 1, 2, 3, 6, 9, 18. The factor pairs are 1×18, 2×9, 3×6.

  25 = 5×5 (prime factorization).

Unique subsets are {}, {5}, {5,5}. Divisors are 1, 5, 25. Factor pairs are 1×25, 5×5.

The purpose of an exponent is to indicate repeated multiplication. That is, just as 2×3 means 2+2+2 (repeated addition), the use of an exponent means repeated multiplication: 2³ means 2×2×2.

This idea can be extended to give several rules of exponents--rules for multiplication, division, powers, and roots. All of these rules derive from the basic idea of repeated multiplication.

The number that is repeatedly multiplied is called the base. The exponent is called the power.

In plain text, the caret (^) symbol is used to signify an exponent. If an exponent is other than a single number or variable, it must be enclosed in parentheses, so that there is no confusion regarding what the exponent consists of. (This is an "order of operations" issue, since exponentiation must happen before any other operation.) In typeset math expressions, an exponent is rendered in superscript text.

31. -30^2 = -900 . . . base is 30, power is 2. The minus sign is not part of the base. Again, this interpretation is based on the "order of operations".

32. 12^4 = 20,736 . . . base is 12, power is 4.
