Answer:

proportional

Step-by-step explanation:

20 : 25 :: 36 : 45

Product of means = 25*36 = 900

Product of extremes = 20 * 45 = 900

Product of means = Product of extremes

So, the number of pages read  is proportional to your time

Answer:

640 foxes

Step-by-step explanation:

The actual formula is [tex]y = 40 * 4^{x}[/tex]

Now that we have the real formula we would need to find out how many 13 year periods exist in the 26 years that are being used in the question. We calculate this by simply dividing 26 by 13.

26 / 13 = 2 periods

Therefore, now that we know there are 2 periods of 13 years in the 26-year span, we plug this value into the formula and solve for y...

[tex]y = 40 * 4^{x}[/tex]

[tex]y = 40 * 4^{2}[/tex]

[tex]y = 40 * 16[/tex]

[tex]y = 640[/tex]

Finally, we can see that there should be 640 foxes after 26 years.

Answer:

The area of the remaining figure is [tex]y^2-x^2[/tex]

Step-by-step explanation:

Area of the Square Shape

Given a square of side length x, the area is calculated by the formula:

[tex]A_x=x^2[/tex]

It's given a square of side x is cut out of a larger square of side y. Please refer to the image below.

The area of the square of side length y is:

[tex]A_y=y^2[/tex]

The shaded area of the remaining figure is the difference between both areas:

[tex]A=A_y-A_x[/tex]

[tex]A=y^2-x^2[/tex]

The area of the remaining figure is [tex]\mathbf{y^2-x^2}[/tex]

Answer:

5/6. Is this what u are looking for?

Step-by-step explanation:

Step 1 Simplify:2x(6)-19=-9 to 12x+-19=-9

Step 2 Add 19 to both sides: 12x-19+19=-9+19. You should get 12x=20

Step 3 Divide 12 on both sides: 12x/12=10/12

x=10/12. Simplified= x=5/6

Answer:

A

Step-by-step explanation:

The segment BC  joining the midpoints of 2 sides of the triangle is

Half the length of the third side, that is

x + 31 = 2(x + 19)

x + 31 = 2x + 38 ( subtract x from both sides )

31 = x + 38 ( subtract 38 from both sides )

- 7 = x → A

Step-by-step explanation:

Answer:

The distance is 338ft

Step-by-step explanation:

Given

Represent distance with s and velocity with v:

When

[tex]s = 200\ ft[/tex]

[tex]v = 50mph[/tex]

Required

Determine the distance when velocity is 65mph

From the question, we understand that:

[tex]s\ \alpha\ v^2[/tex]

Convert to equation

[tex]s\ = kv^2[/tex]

Substitute 200 for s and 50 for v

[tex]200 = k * 50^2[/tex]

[tex]200 = k * 2500[/tex]

Make k the subject:

[tex]k = \frac{200}{2500}[/tex]

[tex]k = \frac{2}{25}[/tex]

To get s when v = 65.

Substitute 65 for v and 2/25 for k in [tex]s\ = kv^2[/tex]

[tex]s = \frac{2}{25} * 65^2[/tex]

[tex]s = \frac{2}{25} * 4225[/tex]

[tex]s = \frac{8450}{25}[/tex]

[tex]s = 338\\[/tex]

Hence, the distance is 338ft

Answer:

[tex]8.234 E14=8.234 \times 10^{14}[/tex]

Step-by-step explanation:

The given number is [tex]8.234 E14[/tex]

We need to write this number in standard form.

Any no is given in the standard form is given by :

[tex]N=a\times 10^b[/tex]

Where

a and b is real no and integer

It means,

[tex]8.234 E14=8.234 \times 10^{14}[/tex]

Hence, this is the required solution.

Answer:

900 black and white copies were printed.

Step-by-step explanation:

From the information provided, you know that they printed 9 black and white copies for every 2 colored copies and you can use a rule of three to find the amount of black and white copies that were printed if they printed 200 color copies:

9 black and white → 2 colored

             x               ← 200 colored

x=(9*200)/2=900

According to this, the answer is that 900 black and white copies were printed.

Answer: Reflect Y-Axis & 10 Units Down

Step-by-step explanation:

Answer:

C. x⁶y⁴/xy²

Step-by-step explanation:

Rearrange (x²y)(x⁴y³) to get

(x²x⁴)(yy³)

When multiplying numbers with exponents with the same base, you add the exponents.

So the equation above can be simplified even further to:

(x²⁺⁴)(y¹⁺³)     --- (those are plus signs in between the exponents)

Simplify to

x⁶y⁴

Now you have the top of the equation simplified

so the answer is c

Answer: D. Even though (0, 0) is not in the table, the graph is a line through (0, 0), so it is proportional.

Step-by-step explanation:

The table is not included but this should be the correct answer.

Linear relationships which are proportional will have to pass through the origin which is (0,0). This does not mean that on the table, the points (0,0) have to be there.

Even if it does not explicitly appear in the table, so long as the line passes the origin, it is to be considered a proportional relationship. The (0,0) might not appear on the table because only a few points the line passed through were listed but if when the line is plotted, the line goes through (0,0), it is proportional.

Answer:

D

Step-by-step explanation:

Answer:

A)3x + 4y = 8

Step-by-step explanation:

Given expression;

          y = [tex]\frac{4}{3} x[/tex]   - 7

A line perpendicular to this will have negative inverse slope;

  the slope of the given line = [tex]\frac{4}{3}[/tex]

  perpendicular line  = [tex]-\frac{3}{4}[/tex]  

 Now;

      the equation of the line is;

           y =  [tex]-\frac{3}{4}[/tex] x  - 7

  multiply through by 4

          4y  = -3x - 28

          4y + 3x  = -28

Answer:

C

Step-by-step explanation:

Step-by-step explanation:

Given

Divide it by the following:

(a) 2x + 1

Quotient =  2x² + 1/2x - 5/4

Remainder = 1/4

(b) 2x - 3

Quotient = 2x² + 4.5x + 5.75

Remainder = 16.25

(c) 4x - 1

Quotient = x² + x - 1/2

Remainder = - 3/2

(d) x + 2

Quotient = 4x² - 5x + 8

Remainder = - 17

Step-by-step explanation:

Given

f(x) = 4x³ + 3x² - 2x - 1

Divide it by the following:

(a) 2x + 1

4x³ + 3x² - 2x - 1 =

(4x³ + 2x²) + (x² + 1/2x) - (5/2x + 5/4) + 1/4 =

2x²(2x+1) + 1/2x(2x + 1) - 5/4(2x + 1) + 1/4 =

(2x + 1)(2x² + 1/2x - 5/4) + 1/4

Quotient =  2x² + 1/2x - 5/4

Remainder = 1/4

(b) 2x - 3

4x³ + 3x² - 2x - 1 =

(4x³ - 6x²) + (9x² - 13.5x) + (11.5x - 17.25) + 16.25 =

(2x -3)(2x² + 4.5x + 5.75) + 16.25

Quotient = 2x² + 4.5x + 5.75

Remainder = 16.25

(c) 4x - 1

4x³ + 3x² - 2x - 1 =

(4x³ - x²) + (4x² - x) - (2x - 1/2) - 3/2 =

(4x - 1)(x² + x - 1/2) - 3/2

Quotient = x² + x - 1/2

Remainder = - 3/2

(d) x + 2

4x³ + 3x² - 2x - 1 =

(4x³ + 8x²) - (5x² + 10x) + (8x + 16) - 17 =

(x + 2)(4x² - 5x + 8) - 17

Quotient = 4x² - 5x + 8

Remainder = - 17
