The time it will take the second crocodile to finish its snack is 120 seconds

Let x represent the rate of the first crocodile and let y represent the rate of the second crocodile.

The two crocodiles working together can finish a snack in 40 seconds. Thus;

(1/x + 1/y)40 = 1

It takes one of the crocodiles 60 seconds to finish its snack. Thus;

(1/x + 1/60)40 = 1

40/x + 2/3 = 1

x = 120 seconds

Answer:

59 percent

Step-by-step explanation:

59 divided by 100 is 0.59, which means 59 percent.

Also, when the total is 100, then the amount out of 100 is the percent ( 59 out of 100 is 59 percent, because it is out of 100).

open the parenthesis

[tex]-4x -2 = 3x-5[/tex]

collect like terms

Expressing the function in terms of tiles will give 4 negative x tiles and 2 negative 1 tiles = 3 x tiles and 5 negative 1 tiles

Note that each terms of the expression were written in tems of tiles. The value with no variables (the constants) are all multiplied with 1 tiles each while those with x variables are multiplied by x tiles based on the sign (whether positive or negative)

Using linear function concepts, it is found that the meaning of 200 in the function P(t) is given by:

the y-intercept of the function and the initial number of seed packets at the beginning of the month.

A linear function is modeled by:

[tex]y = mx + b[/tex]

In which:

In this problem, the function is:

[tex]P(t) = -34t + 200[/tex].

The slope is of m = -34 and the y-intercept is of b = 200, hence the correct option is:

the y-intercept of the function and the initial number of seed packets at the beginning of the month.

[tex]\leadsto[/tex]Let us assume entry fee for child be x

[tex]\leadsto[/tex]Let us assume entry fee for adult be y

[tex]\\[/tex]

[tex]\longrightarrow[/tex]Since Entry fees for 2 children and 1 adult is $90 an equation for entry fees will be formed as -

[tex]\begin{gathered}\\\implies\quad \sf 2\times x + 1 \times y = 90 \\\end{gathered} [/tex]

[tex]\begin{gathered}\\\implies\quad \sf 2 x + y = 90 \\\end{gathered} \_\_\_\_\_(1) [/tex]

[tex]\longrightarrow[/tex]Similarly, Entry fees for 3 children and 2 adult is $155 , so an equation for entry fees will be formed as -

[tex]\begin{gathered}\\\implies\quad \sf 3\times x + 2\times y = 155 \\\end{gathered} [/tex]

[tex]\begin{gathered}\\\implies\quad \sf 3x + 2y = 155 \\\end{gathered} \_\_\_\_\_(2) [/tex]

Multiplying eq (1) by 2 it will be -

Answer:

  A) Enterprise: E(x) = 50 +0.25x; Hertz: H(x) = 30 +0.45x

  B) see attached graph

Step-by-step explanation:

A) We choose to compare Hertz (lowest daily charge) and Enterprise (lowest mileage charge). In each case, the total charge will be the sum of the daily charge and the product of the mileage charge and number of miles (x).

  Enterprise: E(x) = 50 +0.25x

  Hertz: H(x) = 30 +0.45x

Answer:

k=−(x−h) 2+r 2 +y

Step-by-step explanation:

Subtract (x−h)   from both sides of the equation.

Subtracting (x−h) from itself leaves 0.

Subtract (x−h)from r

Take the square root of both sides of the equation.

Subtract y from both sides of the equation.

subtracting y from itself leaves 0.

Dividing by −1 undoes the multiplication by −1.

Answer:

Infinitely many solutions

Step-by-step explanation:

Given the system:

[tex]\left \{ {{x+2y=0} \atop {10y=-5x}} \right.[/tex]

One way to do it is to use substitution. That means we want to isolate one of the variables in one equation so we can plug it into the other equation. We can isolate [tex]x[/tex] in the first equation by subtracting [tex]2y[/tex] from both sides.

[tex]\left \{ {{x=-2y} \atop {10y=-5x}} \right.[/tex]

Now we know what [tex]x[/tex] is, so we can plug it into the bottom equation.

[tex]10y=-5(-2y)[/tex]

Then we simplify the right side:

[tex]10y=10y[/tex]

Then we divide both sides by 10:

[tex]y=y[/tex]

Since [tex]y[/tex] will ALWAYS be equivalent to itself, no matter what, we know that there are infinitely many solutions.

A notation that correctly describes the given transformation is:

[tex]R_{O, 90\°}, r_{x-axis}[/tex]

A rotation of 90° around the origin, followed by a reflection over the x-axis.

Here you can see that we have a rectangle in the first quadrant, and then it is moved to the third quadrant.

In the image, you can also see that the orientation of the rectangle changes, thus, we have a type of rotation.

A rotation from the first quadrant to the second quadrant would give use the desired orientation of the rectangle, and then we could reflect it over the x-axis to reach the third quadrant, so we can write the transformation as a rotation over the origin of 90° followed by a reflection over the x-axis.

I'm not sure of the notation you use in the options, but this would be written as:

[tex]R_{O, 90\°}, r_{x-axis}[/tex]

That is a rotation of 90° around the origin followed by a reflection over the x-axis.

The second wedge has a greater volume and it is greater by 4.125 in³.

Since the each cheese wedge has a triangular base, its volume V = 1/2bhw where

Given that for the first wedge, b = 2.5 in, h = 4.5 in and w = 3 in, its volume V' = 1/2bhw

= 1/2 × 2.5 in × 4.5 in × 3 in

= 33.75 in³/2

= 16.875 in³

Given that for the second wedge, b = 3 in, h = 4 in and w = 3.5 in, its volume V" = 1/2bhw

= 1/2 × 3 in × 4 in × 3.5 in

= 42 in³/2

= 21 in³

Since V" = 21 in³ > V' = 16.875 in³, the second wedge has a greater volume.

The amount its is greater than the first volume is the difference in their volumes. V" - V' = 21 in³ - 16.875 in³

= 4.125 in³

The second wedge has a greater volume and it is greater by 4.125 in³.
