The density of the cube is 4.1g/cm³

The first step is to calculate the volume

Volume= area³

= 3³

= 27

The density can be calculated as follows

= mass/volume

= 110/27

= 4.1

Hence the density of the cube is 4.1gram/cm³

To solve the inequality, subtract 8 from both sides. The solution is t ≥ 11 or [11, ∞)

Tips to solve linear inequalities:

Interval notation is often used for the solution(s). Recall the differences between a bracket [ or ], and a parenthesis (  or ). A bracket means the endpoint is included in the solution while a parenthesis means the endpoint is not included in the solution. Remember, infinity ∞ always use a parenthesis.

Example:  x ≥ 2 can be written as [2, ∞), while

                x > 0 is written as (2, ∞)

The given problem:

t+8 ≥ 19

Subtract 8 from both sides. Subtracting a number from both sides will not change the inequality. Hence,

t+8 - 8 ≥ 19 - 8

t ≥ 11

Using the interval notation, the solution is [11, ∞)

When we do Matrix multiplication, we keep these two conditions in mind: 1 The number of columns of the first matrix in the multiplication process must equal the number of rows of the second.

here  number of columns of 1st matrix is not equal to number of rows of 2nd matrix.

To multiply two matrices, we must first determine if the first matrix's number of columns and rows equals the second matrix's number of rows. Then sum all of the results after multiplying each element of the first matrix's column by each element of the second matrix's row.

In dealing with many ideas in linear algebra, matrices are crucial. In mathematics, a matrix is a rectangular array or table with rows and columns of integers, symbols, or expressions. Matrix operations include addition, subtraction, multiplication, and other operations.

The value of "x" in the given figure and question is 20 units.

As per the question statement, We are given a figure in which we are supposed to find the value of x.

Before solving the question, if we observe the figure, we can conclude that this question will include the concepts of right angled triangle or specifically Pythagoras Theorem, which states that

[tex]Perpendicular^{2} + base^{2} = hypotenuse^{2}[/tex] where perpendicular, base and hypotenuse are the three sides of the right angled triangle.

In Triangle RTQ

using Pythagoras Theorem

[tex]RQ^{2} = TQ^{2} +TR^{2} \\RQ=x\\x^{2} = 16^{2} + TR^{2} \\TR^{2} = x^{2} -16^{2}[/tex]

Now considering triangle SRT

using Pythagoras Theorem

[tex]SR^{2} = RT^{2} + ST^{2} \\SR^{2} = (x^{2} -16^{2}) +9^{2}\\[/tex]

Now considering triangle RSQ

using Pythagoras Theorem

[tex]SQ^{2} = SR^{2} +RQ^{2} \\(9+16)^{2} = SR^{2} + RQ^{2} \\(9+16)^{2} = x^{2} -7^{2}+x^{2} \\ (9+16)^{2} =2x^{2} -7^{2} \\25^{2}+7^{2} = 2x^{2}[/tex]

[tex]2x^{2} =674[/tex]

Answer: 13,000

Step-by-step explanation:

First look at the first number given and it's decimal place.

Once you figure the decimal place look for the number it is being multiplied by.

Next look at the number it's to the power to.

In this case the number is 4 so the decimal place of the first number will be moved over to the right 4 times.

Next look at the second number given and calculate what the number is to the power of and after multiply the first given number.

Lastly, once you have multiplied You will receive your final given answ⊕er and that will be the standard form.

The equation illustrates that the number of miles will be 3 miles.

The taxi company charged a pick- up fee of $2.90 plus $1.25 per mile.

Let the number of miles be m.

Therefore, this will be:

2.90 + (1.25 × m) = 6.65

2.90 + 1.25m = 6.65

Collect like terms

1.25m = 6.65 - 2.90

1.25m = 3.75

m = 3.75/1.25

m = 3

The number of miles is 3 miles.

2. What does it mean for a number to a perfect square? provide an example.

By squaring a whole number or an integer, one can create perfect squares. Let's examine an illustration to get the idea behind perfect squares. We can use a set of four and a second set of six marbles for this. Let's set the marbles in order.

See the figure(1).

With four marbles, we can create a square with two rows and two marbles in each row. We can create a rectangle with 6 marbles that has 2 rows with 3 marbles in each row. It signifies that 4 = 2[tex]\times[/tex]2 and 6 = 3[tex]\times[/tex]2 mathematically. Let's concentrate just on the square-shaped numerals. Here, 4 = 2 × 2 = [tex]2^{2}[/tex].

Therefore, (x,y)=(-1.4,1.96)

if x =-1

Substituting in the equation [tex]y=x^{2}[/tex]

Then y=[tex]-1^{2}[/tex]

y=1.

Therefore, (x,y)=(-1,1)

if x =0

Substituting in the equation [tex]y=x^{2}[/tex]

Then y=[tex]0^{2}[/tex]

y=0.

Therefore, (x,y)=(0,0)

if x =[tex]\frac{2}{5}[/tex]

Substituting in the equation [tex]y=x^{2}[/tex]

Then y=[tex](\frac{2}{5}) ^{2}[/tex]

y=[tex]\frac{4}{25}[/tex].

Therefore, (x,y)=([tex]\frac{2}{5}[/tex],[tex]\frac{4}{25}[/tex])

if x =2

Substituting in the equation [tex]y=x^{2}[/tex]

Then y=[tex]2^{2}[/tex]

y=4.

Therefore, (x,y)=(2,4)

10. why the graph of equation  [tex]y=x^{2}[/tex] is above x-axis.

Because the [tex]y=x^{2}\\[/tex] the x values are always positive because x as a square. So, the equation is always on x- axis or above x-axis.

The total weight of two animals in scientific notation is 1.3 x 10⁴ lbs.

Scientific Notation:

A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.

For example,

650,000,000 can be written in scientific notation as 6.5 ✕ 10⁸.

Given,

The approximate weights of two animals are 4.23 x 10³ lbs. and 8.7 x 10³ lbs.

Here we need to find the total weight of the two animals and we need to write the final answer in scientific notation with the correct number of significant digits.

The total weight of the two animals is calculated as

Total weight = Animal 1 + Animal 2

So,

Total weight = 4.23 x 10³ lbs + 8.7 x 10³ lbs.

Take 10³ lbs as the common term,

Then we get,

Total weight = (4.23 + 8.7) x 10³ lbs.

Total weight = 12.93 x 10³ lbs.

It can we rewritten as,

Total weight = 1.293 x 10⁴ lbs.

When we round off it, then we get,

Total weight = 1.3 x 10⁴ lbs.

Hence, the total weight of the two animals is 1.3 x 10⁴ lbs.

Step-by-step explanation:

If, thats the whole question.

The length of the sum of the smallest value and the largest value is 105 feet.

Given data

BA = x + 30

BC = 2x + 10

CD = x + 20

Perimeter = 120 feet

The perimeter refers to the sum of all the dimensions which is given as 120 feet. We sum the dimensions given to find the value of x.

This is done as follows:

Perimeter = BA + BC +CD

120 = x + 30 + 2x + 10 + x + 20

120 = x + 2x + x + 30 + 10 + 20

120 = 4x + 60

4x = 120 - 60

4x = 60

x = 60 / 4

x = 15

plugging in x = 15 into the dimensions given we have

BA = x + 30

BA = 15 + 30

BA = 45

BC = 2x + 10

BC = 2 * 15 + 10

BC = 30 + 40

BC = 70

CD = x + 20

CD = 15 + 20

CD = 35

Hence we can say that the smallest value is 35 and the largest value is 70.

sum of the values

70 + 35 = 105

The sum of the smallest value and the largest value is 105 feet.
