Which box shows a relationship where the constant of proportionality is 64?
Sever21 [200]

Answer:

C

Step-by-step explanation:

Constant of proportionality = \frac{y}{x}

Let's find out which if the boxes will give us 64 as constant of proportionality.

A. \frac{y}{x} = \frac{11}{2} = 5.5 ≠ 64

B. \frac{y}{x} = \frac{5}{15} = \frac{1}{3} ≠ 64

C. \frac{y}{x} = \frac{16}{\frac{1}{4}} = 16*\frac{4}{1} = 64 ≠ 64

D. \frac{y}{x} = \frac{\frac{3}{7}}{3} = \frac{3}{7}*\frac{1}{3} = \frac{1}{7} ≠ 64

E. \frac{y}{x} = \frac{2}{-10} = -\frac{1}{5} ≠ 64

F. \frac{y}{x} = \frac{21}{6} = \frac{7}{2} ≠ 64

G. \frac{y}{x} = \frac{4}{8} = \frac{1}{2} ≠ 64

From the boxes given, box C is the only box that shows us a relationship where the constant of proportionality is 64.

What is the area of this shape?
Dovator [93]

Answer:

The area of this shape equals 30cm^{2}

Step-by-step explanation:

From the diagram, we can see that this shape is a parallelogram  (since opposite sides are equal to each other). The formula for the area of the parallerlogram is as follows:

Area = bh (where "b" is the base, and "h" is the height).

And so we get...

Area = bh = (10)(3) = 30cm^{2}

Help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
shusha [124]

Answer:

24

Step-by-step explanation:

You need to plug in 3 for all of the x-values

That looks like 2(3)^2 + 5(3) - 9

Then if you simplify it is 2(9) + 15 - 9

Then simplify one last time and you get a final answer of 24
