Answer:

Amber is fossilized tree resin that has been appreciated for its color and natural beauty since Neolithic times. ... There are five classes of amber, defined on the basis of their chemical constituents. Because it originates as a soft, sticky tree resin, amber sometimes contains animal and plant material as inclusions.

Answer and Step-by-step explanation:

(4 × 5 + 2)(3 - (2 × 3))

I think this is it but I'm not sure.

22 × -3 = -66 is I think the answer.

Answer:

98/15

Step-by-step explanation:

[tex](\frac{4}{5} +2)[/tex][tex](3-\frac{2}{3} )[/tex]

=(4 + 5*2)/5  (3*3 -2)/3

=(4+10)/5  (9-2)/3

=(14/5 )(7/3)

if there is no any sign between the two fraction inside bracket then it means to multipli.

=14/5 * 7/3

=14*7/5*3

=98/15

2 hours and 32 minutes

Step-by-step explanation:

John Read a book at 11:32 and stopped at 2:14

What you have to do is add minutes up and hours up until you get to 2:14pm and all the hours and minutes it took to get there you add up and thats ur answer :)

Answer:

$81.10

Step-by-step explanation:

Profit = total revenue - total cost

1 liter = 1000 mm

7 liter = 7000 mm

Number of jars needed = 7000 / 250 = 28

total revenue = number of jars sold x price per jar

28 x  $8.95 = 250.60

Total cost = $155.50 + (0.5 x 28) = 169.50

Profit = 250.60 -  169.50 = 81.10

13/12 x²

Answer:

First number = 147

Second number = 105

Step-by-step explanation:

Let the two numbers be 7x and 5x

7x - 5x = 42

2x = 42

x = 21

First number = 7x = 7 x 21 = 147

Second number = 5x = 5 x 21 = 105

Hope this helps!

Answer:

A = -7.5   B = -17.5

Step-by-step explanation:

A + B = -25

A = B + 10

Plug the second equation into the first equation:

B + 10 + B = -25

2B = -35

B = -17.5

Plug that value into the first equation:

A - 17.5 = -25

A = -7.5

Answer:

[tex]x[/tex] would be [tex](1/3)[/tex] when [tex]y = 3[/tex].

Step-by-step explanation:

The question states that [tex]x[/tex] varies "inversely" as [tex]y^2[/tex]. In other words, there is a non-zero number [tex]a[/tex] (a constant) such that:

[tex]\displaystyle x = \frac{a}{y^2}[/tex].

The challenging part is to find the value of [tex]a[/tex] in this equation.

Given that [tex]x = 3[/tex] when [tex]y = -1[/tex], replace the [tex]x[/tex] in this equation with [tex]3[/tex] and [tex]y[/tex] with [tex](-1)[/tex]. This equation should still be valid:

[tex]\displaystyle 3 = \frac{a}{(-1)^{2}}[/tex].

Solve for [tex]a[/tex]:

[tex]a = 3 \times (-1)^2 = 3[/tex].

Hence, the relation between [tex]x[/tex] and [tex]y[/tex] becomes:

[tex]\displaystyle x = \frac{3}{y^2}[/tex].

Find the value of [tex]x[/tex] when [tex]y = 3[/tex] by replacing the [tex]y[/tex] in this equation with [tex]3[/tex].

[tex]\displaystyle x = \frac{3}{3^2} = \frac{1}{3}[/tex].

In other words, the value of [tex]x[/tex] would be [tex]\displaystyle \frac{1}{3}[/tex] when [tex]y = 3[/tex].

Answer:

C =(x-3)(x-2)/x

or

x²-5x+6/x

Step-by-step explanation:

2x^2 - 4x - 6/x + 2 * x^2 - 4/2x^2 + 2x

Factorizing the given factors

1) 2x^2 - 4x - 6

= 2x^2 - 6x+2x - 6

= 2x(x-3) +2(x-3)

= (x-3)(2x+2)

2) x^2 - 4

= (x+2) (x-2)

3) 2x^2 + 2x

= 2x( x+1)

Putting the factors

(x-3)(2x+2)/x + 2   *  (x+2) (x-2)/2x( x+1)

= (x-3)(2x+2) (x-2)/2x( x+1)

= 2(x-3)(x+1) (x-2)/2x( x+1)

=(x-3)(x-2)/x

Now multiply

(x-3)(x-2) =x²-5x+6

Then the answer becomes  x²-5x+6/x

Answer:

Rectangular prisms are six-sided polygons; three-dimensional shapes of which all sides meet at 90-degree angles, like a box. Cubes are a special type of rectangular prism of which all sides are the same length; this is the key difference between cubes and other rectangular prisms.

Answer:

Hello! answer: 268 square meters

Step-by-step explanation:

To find the total surface area you find the area of each face then add them up so...

10 × 3 = 30

10 × 3 = 30

8 × 3 = 24

8 × 3 = 24

10 × 8 = 80

10 × 8 = 80

Now that I found the area for each face I will just add them up so...

30 + 30 + 24 + 24 + 80 + 80 = 268 therefore the area is 268 square meters Hope that helps!

[tex] \large\mathrm {\boxed{ \boxed{268 \: \: m {}^{2} }}}[/tex]

Answer/Step-by-step explanation:

Mean is a measure of center tendency which can be said to be the average value of a set of data. It can be referred to as the commonest value in a data set. It is the sum of all data values in a given set divided by the number of values.

For example, a test score for a class of 5 is given as 5, 6, 2, 4, 7

The mean = sum of all values/number of data values

= (5 + 6 + 2 + 4 + 7)/5

= 24/5

Mean = 4.8

Answer:

Step-by-step explanation:

132-5 therefore the height from the eyes to the window is 127

100 feet away from the base of the tower  

This forms two legs of a triangle

trying to find the degrees of this triangle.

Since its the two legs, you can use tanx which = to opposite side/adjacent side

Therefore, it is tanx = 127/100

But you are looking for x so arctan(1.27)

Must use calculator to find x

Answer:

3/10

Step-by-step explanation:

There are 52 cards in a deck. This means that there are four of each one. If all types of all three cards are removed, there are still 40 cards. There are 12 face cards. 12/40 is 3/10

Answer:

3/13

Step-by-step explanation:

Total cards in a deck=52

There are four cards of each number which in this case is 2,3,4

Total of 2s,3s,and 4s=12

12/52 simplify this and u get

3/13

Given:

The lengths, in inches, of each fish are listed:

9, 13, 9, 21, 18

To find:

The statement that best represents the meaning of the range for these data.

Solution:

The given data values are:

9, 13, 9, 21, 18

Arrange the data values in ascending order.

9, 9, 13, 18, 21

Here, the maximum value is 21 and the minimum value is 9.

We know that,

[tex]\text{Range}=\text{Maximum value}-\text{Minimum value}[/tex]

[tex]\text{Range}=21-9[/tex]

[tex]\text{Range}=12[/tex]

The range of the data set is 12. Therefore, the difference between the shortest and longest fish is 12 inches.

Answer:

y = 5

Step-by-step explanation:

3y - 2 = 13

We are solving for y, so we want to isolate it.

Add 2 to both sides.

3y = 15

Continue isolating y by dividing both sides by 3.

y = 5

Check your answer by plugging it back into the original equation.

3y - 2 = 13

3(5) - 2 = 13

Multiply.

15 - 2 = 13

Subtract.

13 = 13

Your answer is correct.

Hope this helps!

Answer:

y = 5

Step-by-step explanation:

Get y by itself:

3y - 2 = 13

     +2    +2

3y = 15

Divide by 3:

3y = 13

÷ 3    ÷ 3

y = 5

Answer:

y = - 2x + 5

Step-by-step explanation:

m , ( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )

y - [tex]y_{1}[/tex] = m( x - [tex]x_{1}[/tex] )

~~~~~~~~~~~

m = - 2 and ( 4 , - 3 )

y - ( - 3 ) = - 2( x - 4 )

y + 3 = - 2x + 8

y = - 2x + 5

Answer: [tex]\text{m}\angle T=45^{\circ}[/tex]

Step-by-step explanation:

Given: In ΔSTU, [tex]\text{m}\angle S = (2x+10)^{\circ}[/tex] , [tex]\text{m}\angle T = (3x-9)^{\circ}[/tex], [tex]\text{m}\angle U = (6x-19)^{\circ}[/tex]

To find: [tex]\text{m}\angle T[/tex].

We know that the sum of all the angles of a triangle is [tex]180^{\circ}[/tex].

In ΔSTU,

[tex]\text{m}\angle S+\text{m}\angle T+\text{m}\angle U=180^{\circ}\\\\ 2x+10+3x-9+6x-19=180\\\\ 11x-18=180\\\\11x =180+18\\\\11x=198\\\\x=\frac{198}{11}\\\\ x=18[/tex]

[tex]\text{m}\angle T = (3(18)-9)^{\circ}\\\\=(54-9)^{\circ}\\\\= 45^{\circ}[/tex]

Hence, [tex]\text{m}\angle T=45^{\circ}[/tex]
