Answer:

3. 9.2 mL; 4. 0.25 mL

Step-by-step explanation:

3. 12 mL syringe

The arrow points to the first division between 9 mL and 10 mL.

There are five divisions, so

5 divisions = 1.0 mL or

 1 division = 0.2 mL

The reading is  

9.0 mL + 0.2 mL = 9.2 mL

4. 0.5 mL syringe

The arrow points to the fifth division between 0.20 mL and 0.30 mL.

There are 10 divisions, so

10 divisions = 0.10 mL or

   1 division = 0.01 mL

 5 divisions = 0.05 mL

The reading is  

0.20 mL + 0.05 mL = 0.25 mL

A coffee distributor plans to mix some Rift Valley coffee that normally sells for $12.10 per pound with some Mexican Shade Grown
-BARSIC- [3]

Answer:

24 pounds of Rift Valley coffee

26 pounds of Mexican Shade Grown coffee

Step-by-step explanation:

If R is pounds of Rift Valley coffee, and M is pounds of Mexican Shade Grown coffee, then:

R + M = 50

12.10 R + 13.10 M = 12.62 (50)

Substitute:

12.10 R + 13.10 (50 − R) = 12.62 (50)

12.10 R + 655 − 13.10 R = 631

R = 24

M = 26

Triss [41]

The amount of money in the account after 10 years is $278,814.10.

<h3>What will be the value of the account after 10 years?</h3>

The first step is to determine the amount she has left to invest.

Amount invested = amount won - amount spent on vacation

$250,000 - $10,000 = $240,000

The second step is to determine the future value of the account. The formula for calculating future value:

FV = P (1 + r)^nm

  • FV = Future value
  • P = Present value
  • R = interest rate = 1/5/12 = 0.125%
  • m = number of compounding =12
  • N = number of years

240,000 x 1.00125^(12 x10) = $278,814.10
