The Chemistry Club is experimenting with different mixtures of water with a certain chemical (sodium polyacrylate) to make fake snow.
To make each mixture, the students start with some amount of water, and then add of that amount of the chemical, and then 9 more grams of the chemical. The chemical is expensive, so there can’t be more than a certain number of grams of the chemical in any one mixture.

Answer:

  1) x = 4

  2) ? = 20

  8) x = 5

Step-by-step explanation:

Use the applicable relationships to write an equation involving the unknown. Solve the equation.

__

1) We note that the marked arcs are the same length. In a circle, chords that subtend arcs of the same measure are the same length.

  5x -1 = 4x +3

  x = 4 . . . . . . . . . . add 1-4x to both sides

__

2) A tangent meets a radius at right angles. The given triangle is a right triangle, so the Pythagorean theorem applies.

  12² +16² = x²

  144 +256 = x² = 400

  x = √400 = 20

The missing value is 20.

__

8. Tangents from the same point are the same length.

  4x -8 = 12

  4x = 20 . . . . . add 8

  x = 5 . . . . . . . divide by 4

_____

Additional comment

In problem 2, you note the ratio of side lengths is 12 : 16 = 3 : 4. This should give you a clue that this is a 3-4-5 right triangle. The long (missing) side will be 5, scaled by the scale factor of 4, so will be 4×5 = 20.

What is 767,000 expresses in scientific notation

Answers

Answer:

767,000 in scientific notation is [tex]7.67*10^5[/tex].

Step-by-step explanation:

A number is written in scientific notation when there is a number greater than or equal to 1 but less than 10 and multiplied by a power of 10. In this case, if 767,000 were to be written in scientific notation, then you need to move the decimal place of the number until you have a number that meets the requirement above. 7.67 would be the number to use, and you need to multiply that by a power of 10 that makes the product the original number, so the power would be 5. So 767,000 in scientific notation would be [tex]7.67*10^5[/tex].

The answer is 767,000

Lucy is painting one wall in her bedroom. The wall measures 13 feet long and 9 feet wide. If one can of paint covers 50 square feet will it be enough?

Answers

The area of the wall is figured by length * width.
Area of wall = 13*9=117 square feet
Since one can covers only 50 square feet you will not have enough with one can. You will need 117/50=2.34 cans. Assuming you can only buy full cans you would need to buy 3 cans.

Point P divides the directed segment from A to B in the ratio 9 to 2. The coordinates of point A are
(-4,-2) and the coordinates of point P are (2, 1). Find the coordinates of point B. Round your answer to
the nearest tenth if necessary.

Answers

Answer:

[tex]B =(3.3,1.7)[/tex]

Step-by-step explanation:

Given

[tex]A(x_1,y_1) = (-4,-2)[/tex]

[tex]P(x,y) = (2,1)[/tex]

[tex]m : n = 9 : 2[/tex]

Required

The coordinates of [tex]B(x_2,y_2)[/tex]

The line segment from ratio is calculated as:

[tex](x,y) = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})[/tex]

Substitute: A, P, m and n

[tex](2,1) = (\frac{9 * x_2 + 2*-4}{9+2},\frac{9*y_2 +2 *-2}{9+2})[/tex]

[tex](2,1) = (\frac{9x_2 -8}{11},\frac{9y_2 -4}{11})[/tex]

Multiply through by 11

[tex](22,11) = (9x_2 -8,9y_2 -4)[/tex]

By comparison:

[tex]9x_2 - 8 = 22[/tex]

[tex]9y_2 - 4 = 11[/tex]

So, we have:

[tex]9x_2 - 8 = 22[/tex]

[tex]9x_2 = 22 +8[/tex]

[tex]9x_2 = 30[/tex]

Solve for x2

[tex]x_2 = 30/9[/tex]

[tex]x_2 = 3.3[/tex]

[tex]9y_2 - 4 = 11[/tex]

[tex]9y_2 = 11+4[/tex]

[tex]9y_2 = 15[/tex]

Solve for y2

[tex]y_2 =15/9[/tex]

[tex]y_2 =1.7[/tex]

So, the coordinates of B is:

[tex]B =(3.3,1.7)[/tex]
