Isaac is making soft pretzel nuggets. His recipe says that, after he makes the dough, he should divide it into 8 equal pieces. T
Romashka-Z-Leto [24]

Answer:

The answer to your question is 192 pretzels

Step-by-step explanation:

Data

number of pieces = 8

length of each piece = 2 ft

length of each pretzel = 1 in

number of pretzels = x

Process

1.- Convert ft to in

                        1 ft --------------- 12 in

                         2 ft --------------- x

                         x = (2 x 12) / 1

                         x = 24 ft

2.- Divide the length of each piece by the length of each pretzel

                       24/1 = 24 pretzels per piece

3.- Multiply the number of pretzels per the number of pieces

                       24 x 8 = 192 pretzels

blagie [28]

Answer:

Step-by-step explanation:

The expected return is given as

Expected Return = SUM (Return i x Probability i). i=1,2,3.....

First investment

Probability of 0.7, it returns 60cents per dollars

Second investment

Probably of 0.3, it loses 20cents per dollar.

Expected return=(0.7×60)-(0.3×20)

Excepted return= 42-6

Excepted return=36cents

To dollars, 1cents is 0.01dollars

Then, 36cents = 0.36dollars

Expected return=$0.36
