Mr. Gardener invested $500,000. His annual interest was $40,000. What was the annual interest rate?
Mademuasel [1]

Answer: The annual interest rate r= 8%

Step-by-step explanation:

Given: The invested amount =  $500,000.

The annual interest = $40,000

The annual interest rate is given by :-

r=\frac{\text{interest}}{\text{invested amount}}\times100\\\\\Rightarrow\ r=\frac{40,000}{500,000}\times100\\\Rightarrow\ r=\frac{4}{50}\times100\\\\\Rightarrow\ r=8\%

Hence, the annual interest rate r= 8%

a circuit overloads at 1800 watts of electricity you plug a microwave oven that uses 1100 watts into the circuit write and solve
Bogdan [553]
Let w be the additional watts you can add on the circuit.

1100 + w < 1800 (write the inequality)
-1100 -1100 ( - 1100 from each side)

w < 700 (simplify)


ANSWER:
You can add up to 700 watts to the circuit, which means that you can also plug in the clock radio and the blender.


LOOK BACK:
You can check that your answer is correct by adding the numbers of watts used by the microwave oven, clock radio and blender.

1100 + 50 + 300 = 1450

The circuit will not overload because the total wattage is less than 1800 watts.

Part of your job as manager is to count the cash for the daily bank deposit. When you count the cash, you have 47 ones, 22 fives
cluponka [151]

Answer:

$592.92

Step-by-step explanation:

Bills:

47 ones = 47*1 = $47

22 fives = 22*5 = $110

9 tens = 9*10 = $90

17 twenties = 17*20 = $340

Total Bills: 47+110+90+340 = $587

Coins:

67 pennies = 67*1 = $0.67

12 nickels = 12*5 = $0.60

9 dimes = 9*10 = $0.90

15 quaters = 15*25 = $3.75

Total Coins: 0.67+0.6+0.9+3.75 = $5.92

Total: $587+$5.92 = $592.92
