Proportional reasoning involves comparing two values using a known proportion.

Here in a sample of 100 students, 14 students chose Yosemite as their favourite national park. This gives a proportion of 14 / 100 = 0.14 or 14%.

Using proportional reasoning, we will expect 14% of the population of 1,500 students to choose Yosemite as their favourite park.

Therefore, the number of<span> students out of the 1,500 that we would expect to pick Yosemite for their favorite national park</span>  is 14% 0f 1,500 = 0.14 x 1,500 = 210 students.

There are 7 coins that look identical.One of the seven coins weighs slightly less than the other 6. Using a balance scale, how c
RoseWind [281]
Start by putting two coins on each side of the scale. If one side is higher, then the light coin must be in that pair (use a second weighing to determine which of that pair is the lightest.)
If the initial weighing shows the two pairs to be even, discard those four and go to the three others. Put two of the coins on the scale - one on each side. If one side stays higher, that coin is your light one. If however they are equal, the final unweighed coin must be the lighter coin.

What is the area of the square adjacent to the third side of the triangle?
Naddik [55]

Answer:

85 units^2 = Area of Blue Square

and

x = 5 units

Step-by-step explanation:

To do this we use the Pythagorean theorem (a^2 + b^2 = c^2). a and b represent the legs of the triangle whereas c represents the longest side of the triangle, or the hypotenuse.

Since we know the area of a square is the side length multiplied by itself (or the side length squared), \sqrt{35} is the side length of the pink square and \sqrt{50} is the side length of the green square.

That means a = \sqrt{35} and b = \sqrt{50} , so...

(\sqrt{35} )^{2} + (\sqrt{50})^{2}  = c^{2}

35 + 50 = c^2

85 = c^2

\sqrt{85} = c

Now we need to square the square root of 85 to find the area of the blue square.

(\sqrt{85})^{2}  = Area of blue square

85 units^2 = Area of Blue Square

To solve the other question we use the same formula again.

x^2 + 12^2 = 13^2\\x^2 +144 = 169\\-144\\x^2 =  25\\x=\sqrt{25} \\x=5

x = 5 units

PLEASE HELP I DONT UNDERSTAND I HAVE A FEW MIN TO SUBMIT
Lunna [17]

Answer:

Increasing: (\infty, -1) \cup (2, \infty)

Decreasing: (-1, 2)

Step-by-step explanation:

So when an equation has and odd degree, it will go in the opposite direction on both ends, so if y went towards infinity as x went towards infinity, then y would go towards negative infinity as x goes towards negative infinity. In this case, by looking at the graph it has an odd degree, due to opposite end behaviors, although on both ends it's increasing because even though it appears that it's going down on the left side, that's only if you start from the right and go towards the left. So it's really increasing from negative infinity to -1, and then it decreases from -1 to 2, until it once again starts increasing from 2 to infinity. This can be represented as (-infinity, -1) U (2, infinity) for increasing and (-1, 2) as decreasing

2 right triangles have identical angle measures but different side lengths. The first triangle has side lengths of 6, 10, 8 and
musickatia [10]

Answer:

The transformation is 0.5

Step-by-step explanation:

The lengths of the second triangle is just half the length of the first triangle, from the center. As it is just resizing, the angles would not change, resulting in the same triangle, except for size.
