Answer:
Step-by-step explanation:
Convert to a mixed number by placing the numbers to the right of the decimal over
100
. Reduce the fraction. Then, convert the mixed number to an improper fraction by multiplying the denominator by the whole number and adding the numerator to get the new numerator. Place this new numerator over the original denominator.
2^2=4
15^2=225
4+225=229
Square root of 229 is about 15.1
Answer:15.1 (Already rounded time tenths place)
Answer:
50 miles
Step-by-step explanation:
hello,
let's note x the number of miles travelled heading west,
it takes 1 hour to travel 25 miles
so it takes x/25 hours to travel x miles
we know that in total it travels 7 hours so it will travel 7-x/25 hours heading North, then heading North it takes 1 hour to travel 19 miles
so in 7-x/25 hours it travels 19(7-x/25) miles
we can write, as the total distance is 145 miles
we can verify
50 miles heading West takes 2 hours
in 5 hours it travels 19*5 = 95 miles
the total is 145 miles
so this is correct
hope this helps
Answer:
Consider the number of children to be x.
So, 144 coins were divided amongst x children.
For x-3 children, each child would have 16 coins
So, (x-3)*16=144
Solving for x, x-3=144/16
or x-3=9
or x=9+3=12
Answer is 12
Answer:
Since all triangle angles add up to 180°, you can set all the angles equal to 180.
(96 + 2x + (x + 12)) = 180
You can now simplify it together
108 + 3x = 180
Now you can isolate x by itself
180 - 108 = 72
72 / 3 = 24
x = 24
