g100num [7]

Answer:

13\frac{1}{3}\ cookies

Step-by-step explanation:

we know that

Amar makes each cookie with 6 oz of cookie dough

we have

5 lb of cookie dough

Convert to ounces

1 lb=16 oz

so

5 lb=5*16=80 oz

Using proportion

Let

x ------> the number of cookies

\frac{1}{6}\frac{cookie}{oz}=\frac{x}{80}\frac{cookies}{oz}\\\\x=80/6\\ \\x=13.33\ cookies

Convert to mixed number

13.33=13\frac{1}{3}\ cookies

therefore

He can make 13\frac{1}{3}\ cookies

valentina_108 [34]

114 rabbits are released in an isolated area free of predators

When month =0 , the rabbits = 114

3 years = 36 months

When months = 36 , then rabbits = 912

(0,144) and (36, 912)

Exponential growth equation is y = ab^x

Plug in each point and solve for 'a'  and 'b'

114= ab^0  so a= 114

(36, 912)

912= 114b^{36}

Divide both sides by 114 and then take 36th root on both sides

8 = b^36

b = 1.05946

so exponential equation is y= 114(1.05946)^x

x is the number of months and y is the population

to find the population be after another 3 months

Plug in 36+3= 39 for x  and find out y

y= 114(1.05946)^{39}

y= 1084.43336

so , 1084 rabbits after another 3 months
