Alchen [17]

Answer:

a) The system that models the situation is:

p + 0.2m = 3

p + m = 5

b) The solution of the system is:

m = 2.5

p = 2.5

Step-by-step explanat:

It is desired to obtain 5 pounds of a mixture containing 40% peanuts and 60% almonds.

It has a mixture of 20% peanuts and 80% almonds.

p: number of pounds of peanuts

m = amount of mixture

The equation that represents the amount of peanut and mixture that is needed is:

p + m = 5 pounds

m = 5-p (i)

The amount of peanut in total that the mixture should have is:

p + 0.2m = 0.6 (5)

p + 0.2m = 3 (ii)

a) The system that models the situation is:

p + 0.2m = 3

p + m = 5

Now we substitute (i) in (ii) and clear p.

p + 0.2 (5-p) = 3

p-0.2p = 2

p = 2.5 pounds

Now we find m

m = 5 - 2.5

m = 2.5 pounds

b) The solution of the system is:

m = 2.5

p = 2.5

Harman [31]

Answer:

Length of mammoth's tusk in  poster = 15.33

Step-by-step explanation:

Actual height of mammoth = 10 feet 5 inches = 126 inches

Height on the poster of mammoth = 14 inches

Actual length of mammoth's tusk = 11.5 feet = 138 inches

Length of mammoth's tusk in  poster = x

126 : 14  :: 138  : x

Product of mean = product of extremes

x * 126 = 14 * 138

x = \frac{14*138}{126}

x = 15.33
