Answer:

you need to find out how many miles per hour irst then see how many itll be in 24 hours

Step-by-step explanation:

Answer:

D = 6.2t, where t is in hours

Now, solve for 24 hours for t.

D = 6.2(24) = 148.8 miles in 24 hours.

Step-by-step explanation:

First, find out how far the butterfly can fly in 1 hour.

93 miles / 15 hours = 6.2 miles per hour

Let D = the distance in miles the butterfly can fly in t hours.

Your equation will be

D = 6.2t, where t is in hours.

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:

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:

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:

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:

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]

Step-by-step explanation:

3^x=78

x=3.97

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

[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:

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:

Options (1), (2), (3)

Step-by-step explanation:

Let the equation of the line is,

y = mx + b

Here m = slope of the line

b = y-intercept

Given line on the graph is passing through two points (-3, 0) and (0, 1).

Slope of this line will be,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

   = [tex]\frac{1-0}{0+3}[/tex]

   = [tex]\frac{1}{3}[/tex]

y-intercept of the line 'b' = 1

Equation of the line will be,

y = [tex]\frac{1}{3}x+1[/tex]

If the points given in the options satisfy the equation, they will be the solution of the line.

Option (1),

For (3, 2),

2 = [tex]\frac{3}{3}+1[/tex]

2 = 2

True.

(3, 2) is the solution.

Option (2)

For (21, 8),

8 = [tex]\frac{21}{3}+1[/tex]

8 = 8

True.

(21, 8) is the solution.

Option(3)

For (-15, -4),

-4 = [tex]\frac{-15}{3}+1[/tex]

-4 = -4

True.

(-15, -4) is the solution.

Option (4)

For (12, 9)

9 = [tex]\frac{12}{3}+1[/tex]

9 = 5

False

(12, 9) is not the solution.

Option (5)

For (-6, 1)

1 = [tex]\frac{-6}{3}+1[/tex]

1 = -1

False

(-6, 1) is not the solution.

Therefore, Options (1), (2), (3) are the solutions.
