Answer:

40x=120

10r=130

Step-by-step explanation:

8(5x=15-5y)= 40x=120-40y

5(8y+26=2r)= 40y+130=10r

40x=120-40y

10r=130+40y

40x=120

10r=130

In 1979, zoologists estimated the number of fish in a local pond to be about
540. In 1989, 10 years later, the zoologists estimated that the number of
fish had increased to 990. Assuming that the fish population increased
linearly, how many fish lived in the pond in 1986? *
ann

Answers

Answer:

693 fish

Step-by-step explanation:

In 10 years, we can tell that the amount of fish increased by 1.833...(990 divided by 540) times. If we divide 1.833... by 10, we can find how much the pond increases by yearly. we get 0.1833... If we multiply that by 7 (because the gap between 1986 and 1979 is 7 years), we get 1.2833... So, if we multiply 540 by 1.28333..., we get 693 fish.

Aaron puts $1,000 in an account that pays 10% interest compounded quarterly. He leaves it in the account for six months. Estimate how much interest he earns.

Answers

Answer: $50.63 --- Interest

Step-by-step explanation:

Step 1

Using the formulae

A = P(1 + r/n)^nt

Where

A = principal + interest Amount

P = Principal Amount = $1000

t = Time  in years= 6months = 0.5 years

n = number of compounding periods= quarterly =4

Step 2

6 months = 6/12 = 0.5 years

Rate = 10 % = 0.1

A = P(1 + r/n)^nt

= 1000 ( 1 + 0.1/4)^(4 x 0.5)

=1000(1 +0.025)^2

= 1000(1.025)^2

= 1000 x 1.050625

A= $1,050.625

but A = principal + interest Amount

Interest = A- Principal=$1,050.625-$1,000

=$50.625

Cost of ingredients:
Pineapple Juice
Lemons 50 each
Limes 40c each
Lemonade (2 liter bottle) $1.60
Orange juice (1 liter carton) 80c
Pineapoe juice (1 liter carton) 90c

Answers

Answer:

1) 5 limes, 5 lemons, 1,000 mL of pineapple juice, 2,000 mL of lemonade, 1,000 of orange juice

2) Limes = $2, Lemons = $2.5, Lemonade = $1.60, Orange Juice = 80c, Pineapple Juice = 90c

Step-by-step explanation:

1/2 limes · 10 = 5

1/2 lemons · 10 = 5

100 mL of pineapple juice · 10 = 1,000 mL

200 mL of lemonade · 10 = 2,000 mL

100 mL of orange juice · 10 = 1,000 mL

Cost:

5 limes · 0.4 = $2

5 lemons · 0.5 = $2.5

mL to L

1,000 mL of pineapple juice = 1 L, this costs 90¢

2,000 mL of lemonade = 2 L, this costs $1.60

1,000 mL of orange juice = 1 L, this costs 80¢

Overall:

5 limes for $2

5 lemons for $2.5

1 L of of pineapple juice for 90¢

2 L of lemonade for $1.60

1 L of orange juice for 80¢
