First work out the parenthesis:
9x⁴y⁴ / 3y²
Then get rid of the denominator using 9/3=3 and y⁴/y² = y²
3x⁴y² is the simplest form.
1/2 a pound per dog
3 1/2=3.5lbs
3.5÷7=.5
.5=1/2
Answer:
It's so messy but here it is
Step-by-step explanation:
We'll be looking for time here.
s=d/t
ts=d
t=d/s
------------------------
Average speed is:
s=(55m)/h
Distance is:
200m
---------------------------
t=(200m)/(55m/h)
t=(200m/1)*(h/(55m))
t=200/55*h
t≈3.64 hours
Answer:
Step-by-step explanation:
To find the least common multiply, you must descompose 12 and 15 into their prime factors, as you can see below:
12=2*2*3=2²*3
15=3*5
Choose the common and non common numbers with their greastest exponents:
3*5*2²=60
Now you must choose the common and non common variables with their greastest exponents:
n³
Therefore, you can conclude that the least common multiply is:
