Answer:

b. Independent Variable: interest level, Dependent Variable: performance ; Graph starts low, rises until it reaches a maximum point and then falls

Step-by-step explanation:

The independent variable goes along the x-axis. In this graph, that is interest level.

The dependent variable goes along the y-axis. In this graph, that is performance.

From left to right, the graph starts low and increases. It reaches a maximum point and then falls again.

B. The permormance depends on the interest level in maybe study, or doing well.
Performance is dependent
Interest is independent of performance.
Graph starts low and then falls

Two triangles are similar.The the smaller triangle has side 10,20 and 15 units the larger triangles longest side is 52 units.Wha

Oliga [24]

Answer: The perimeter of the largest triangle = 117 units.

Step-by-step explanation:

Sides of smaller triangle = 10,20 and 15 units

Longest side = 20 units

Longest side of larger triangle = 52 units

Sides of two similar triangles are proportional.

Let k be proportionality constant.

$k=\dfrac{\text{Length in larger triangle}}{\text{Length in smaller triangle}}$

$k=\dfrac{52}{20}\\\\\Rightarrow\ k=\dfrac{13}{5}$

Length of other two sides,

$10\times\dfrac{13}{5}, 15\times\dfrac{13}{5}\ i.e.\ 26\text{ units}, 39\text{ units.}$

So sides of larger triangle = 52 units, 26 units , 39 units

Perimeter of largest triangle = 52 +26+39 = 117 units

Hence, the perimeter of the largest triangle = 117 units.

Find the area of the circle with the given radius or diameter. Use pi = 3.14. d = 10 A =

labwork [276]

The formula in computing the area of the circle is:

A = pi (r)^2

Where r = the radius of the circle

Since you are only given the diameter of the circle, you have to solve for its radius. The radius of the circle is half its diameter. Therefore, the radius of the circle is 5 (10/2).

Now, you substitute the measurements to the formula:

A = 3.14 (5)^2

A = 3.14 (25)

A = 78.5 sq. units

2 triangles are shown. The first triangle has side lengths 35, 20, and 20. The second triangle has side lengths x, 44, 44.

Ad libitum [116K]

The value of x is 77 cm which will make the triangles similar by SSS similarity theorem

Given length of the three sides of one triangle are 35 , 20 and 20

and length of the three sides of another triangle are x, 44,44

We need to find the values of x by using SSS Similarity theorem

We know that triangles are are similar by side - side - side similarity creation and hence the sides are in the same ratio

As both the triangles are isosceles triangles

Therefore ,

x/35 = 44/20=44/20 (Using ratio)

Solving the equation we get

x=44*35/20

x= 77

Hence the value of x is 77cm

Answer:

correct answer is four sixths

Step-by-step explanation:

you can simplify 2/6 to 1/3 and then it would just be 1/3 plus 1/3. This is 2/3 or 4/6! Hope this helps :)
