I do need help with this problem that includes pi. ^_^
Troyanec [42]

Solution:

<u>Note that:</u>

  • Circumference = 50.24 ft = 2πr = πd
  • Dia. = 16 ft.

<u>Divide the diameter both sides.</u>

  • 50.24 ft = πd
  • => 50.24/d ft = πd/d
  • => 50.24/d ft = π

<u>Substitute the diameter in the equation.</u>

  • => 50.24/16 = π (Option A)

Use double angle formulas to find the exact value of sin2x,cos2x, and tan2x
denis-greek [22]
Sin2x = 2sinxcosx;
cos2x = (cosx)^2 - (sinx)^2;
tan2x = (sin2x)/(cos2x);

 cosx = 5/13 from formula (sinx)^2 + (cosx)^2 = 1;

=> sin2x = 120/169;

Y is directly related to x and y is 81 when x is 27 the constant of.variation is
suter [353]

Answer:

The constant of variation is 3

Step-by-step explanation:

Given.

y=81

x=27

And y is directly related to x

y ∝ x

Here k is constant of variation

y=kx

k=\frac{y}{x}--------------(1)

Put the y and x value in equation 1.

k=\frac{81}{27}

k=3

So, the constant of variation is 3.

A company produces 3 tons of cereal each week. How many 12-ounce cereal boxes can be filled each week?
LekaFEV [45]
First, convert 3 tons to ounces. 
3 tons = 96,000 ounces. Divide this by 12 ounces.
96,000/12 = 8000
So, 8000 boxes can be filled each week!
Hope this helps!!
