Answer: 4.5 meters is 45 centimeters.
Step-by-step explanation: The centimeter is just a single digit behind a meter, or in more mathematical terms, a tenth of a meter.
In this case, you can simply multiply 4.5 by 10 or divide 4.5 by one hundreth (or 1/100). In doing so, you'd successfully acheive the value of 45. Study your conversions
Huh? What are you saying?
Step-by-step explanation:
what you did was you multiplied all numbers (incl. pi as number) :
1/6, pi, 1/12, pi
and that gives 0.137077839. no i or pi attached. just the plain result number.
so, if you need to just calculate the factors of pi, but don't need the fully numeric result, then your problem looks like
1/6 × pi × 1/12 × pi = 1/72 × pi²
so, you have an expression of pi² with a factor of 1/72.
you only need to type in all the factors, not pi itself (that's what you need to add at the end yourself).
Answer:
She spent 5 hours mowing lawns.
Step-by-step explanation:
To solve, we will just use some algebra
8h + 20 = 60 | Subtract 20 from both sides
8h = 40 | Divide both sides by 8
h = 5
We can confirm this by plugging it back into the original formula.
8(5) + 20 = 60
40 + 20 = 60
60 = 60
