ratelena [41]

Answer:

720 mi²

Step-by-step explanation:

The map has a scale of 1 in: 30 mi, meaning that for every inch you see on the map, in the real-life location, it will measure 30 miles. So we can find the area of the park on the map and then turn it into miles using the scale:

Area of a rectangle:

A=bh

Replace the known values:

A=(4)(6)\\ A=24

The area on the map is 24 mi², we can turn it to miles using the scale by multiplying our result with 30:

A=(24)(30)\\ A=720

And last but not least, don't forget to put the unit!

3. Which phrase best describes the function of the ATP molecule?
aliina [53]

Answer:

1.) Carries energy

Step-by-step explanation:

A good summary of an ATP molecule is a molecule that transfers energy between cells... meaning it carries energy from cell to cell. Furthermore, energy cannot be destroyed, and cannot be absorbed, only changed and transformed. This leaves us with two options, (1. Carries energy, and 4. None of the above). Since we already have a basic understanding of what an ATP molecule does, we can confidently determine that the correct answer is that an ATP molecule can best be described as carrying energy.

How many solutions are there to the<br>system of equations, x + y = 1<br>and 2x + 2y = 2?​
larisa86 [58]

There are infinitely many solutions of the system of equations, x + y = 1

and 2x + 2y = 2

Step-by-step explanation:

We need to find how many solutions are there to the  system of equations.

x+y=1\,\,\,(1)\\2x+2y=2\,\,\,(2)

Solving:

Multiply equation (1) with 2 and subtract with equation(2)

2x+2y=2\\2x+2y=2\\-\,\,-\,\,\,\,\,\,\,\,\,\,\,\,-\\------\\0=0

Since our answer is 0=0 so, there are infinitely many solutions.

The value of p from the given equation is 136.

The given equation is p/4 - 15 = 19.

<h3>What is an equation?</h3>

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation is solved as follows:

Transpose -15 to other side of the given equation

That is, p/4 = 19+15

⇒ p/4 = 34

Cross multiply 4 to 34

We get p = 34 × 4

⇒ p = 136

Therefore, the value of p from the given equation is 136.
