<u>Answer:</u>

<u>Steps:</u>

A = (35×21)+(21+2×3.5)×21/2

A = 735 + (21+7)×21/2

A = 735 + 28×21/2

A = 735 + 588/2

A = 735 + 294

a recipe calls for 6 cups of brown sugar for every 2 cups of white sugar. How many cups of brown sugar is required for every cup

sammy [17]

Answer:

You need 3 cups of brown sugar for every 1 cup of white sugar.

Step-by-step explanation:

To find the smallest amount possible, divide both numbers by the smaller number. So, 6 (the amount of brown sugar) Divided by 2 equals 3, and 2 (the amount of white sugar) Divided by 2 equals 1.

Answer:

Step-by-step explanation:

The circumference formula is

$2\pi r$

where r is the radius

The circumference of the NAVY Pier Wheel is 439.6

We know the circumference so we solve for r.

$2\pi r=439.6$

$r=69.6=70$

So our radius is 70.

The circumference of Navy is 56% of the original wheel. So we can just set up a proportion.

$\frac{56}{100} =\frac{439.6}{y}$ to find the new circumference.

We simplify that and we get y=485

Know we find the radius,

$2\pi r=785$

r= $\frac{785}{2\pi } =125$

So our radius is 125.

3. The first Ferris wheel circumference is 785. We divide 9 by that to find the wheel movement per minute.

785/9= 87.2 feet per minute
