John is making 3 1/2 batches of cookies. Each batch takes 2 1/4 cups of flour. How much flour will John need for the cookies?
Ivahew [28]

Answer: 7 7/8 cups of flour

Step-by-step explanation:

Since John is making 3 1/2 batches of cookies and each batch takes 2 1/4 cups of flour.

The amount of flours that John will need for the cookies will be gotten by multiply the batches of cookies made by the number of flours of cups used per batch and this will be:

= 3 1/2 × 2 1/4

= 7/2 × 9/4

= 63/8

= 7 7/8 cups of flour

If R is the total resistance for a parallel circuit with two resistors of resistances of r1 and r2 then 1/r=1/r1+1/r2 find the r
Allushta [10]
A little Algebra, and we're home free!

We are given R = 20 and r2 = 75. We need to find r1.

The formula is 1/R = 1/r1 + 1/r2. Plug-in:
1/20 = 1/r1 + 1/75
1/20 - 1/75 = 1/r1
0.0366 = 1/r1
r1 = 1/0.03666
r1 = 27.272

Our answer is r1 = 27 ohms.
