Answer:
Multiply the time per day by the number of days per week.
6/8 x 6 = (6 x 6)/8 = 36/8 = 4 1/2 hours a week.
Step-by-step explanation:
Do recall that squaring and the *radical sign* cancel each other out... like so:(
)
= a
When you put it that way, it isn't enough :P
(
)
= a
(
)
=?
so you start with
(
)
=
8x+1=25 <-- subtract 1 to both sides
8x=24 <- divide 8 to both sides
x= 3
To find out if it's an extraneous solution ask yourself: It mustn't result in a radical that I like to call... 'illegal'. Plug it into the radicand 8x+1 and make sure you get something that is not a negative number.... so, DO you get a negative number when you plug in x = 3 into the radicand?
(extraneous solution is a invalid solution)
x=3 not extraneous
Answer: 57.1 (rounded)
Step-by-step explanation:
Area of triangle formula: 1/2 x base x height
Area of a semicircle: 1/2 x pi x r^2
(1/2 x 8 x 8) + (1/2 x pi x 4^2)
= 57.1 (rounded)
Answer:89%
Step-by-step explanation: its the probability that they will get anything other than an arm tattoo. So you subtract 43 from 389 and it gives you 346,
346/389 x 100% = 88.9%
