Answer: There are five "digits": 0,1, 2, 3, 4
Step-by-step explanation: The base is five. There are five "digits": 0,1, 2, 3, 4 . Positions correspond to integer powers of five, starting with power 0 at the rightmost digit, and increasing right to left. The digit placed at a position shows how many times that power of five is included in the number.
Your answer is $1.26
You can solve this problem with or without a calculator, and I don't know if you're allowed one or not so I'll show you both ways
Calculator:
The easiest way to find percentages of values on the calculator is to use the decimal multipliers, which are just the decimal value of the percentage. For example, 50% would be 0.5, 75% would be 0.75 etc. The decimal value of 15% is 0.15, so you would do 8.40 × 0.15 = 1.26
Non-Calculator:
This is a bit longer, but gives you the same answer. To solve without a calculator, you first divide 8.40 by 10 to find 10%, which is 0.84. Now you can divide that by 2 to find 5%, which would be 0.42, and then you add the two values (because 10% + 5% = 15%) to get 1.26
I hope this helps!
Answer:
Mikhail is 50 years old.
Step-by-step explanation:
Let m represent how old Mikhail is.
110 = (m + 10) + m
Combine equal variables.
110 = 2m + 10
Get the variable alone by cancelling out the 10.
110 - 10 = 2m
Simplify.
100 = 2m
Divide.
m = 50
