446,221 rounded to the nearest ten thousands would be 450,000
Answer:
30 meters away
Step-by-step explanation:
each second is equal to 5 meters, hence meters per second
An adult polar bear is 8 times longer than a newborn.
Newborn= 12 1/2 ft
Multiply this by 8.
But first you have to turn the fraction
12 1/2 into an improper fraction. To do this you have to multiply the denominator, 2, by the whole number, 12, and add the numerator to the product, which totals to 25. The fraction is 25/2. (25/2 * 8/1)= 100 in simplified. 100 inches= 8 1/3 ft long
A= 8 1/3 ft long.
For B, you are dividing since you are trying to figure out the length of a newborn, not an adult polar bear. 9/8 turned into a mixed fraction is
1 1/8 ft. But, it asks in inches.
B= 13 1/2 inches
I know this answer is very long but I hope it helps you understand better!

Answer:
x=6
Step-by-step explanation:
2x - 5 = 7
Add 5 to each side
2x-5+5 = 7+5
2x= 12
Divide by 2
2x/2 = 12/2
x = 6
Answer:
50√3 ≈ 86.6 m
Step-by-step explanation:
The geometry can be modeled by a right triangle with the height of the kite being the leg opposite the 60° angle. The hypotenuse has the given length of 100 m.
The mnemonic SOH CAH TOA reminds you that the relation between angles and the sides of interest here is ...
Sin = Opposite/Hypotenuse
sin(60°) = (kite height)/(100 m)
kite height = (100 m)·sin(60°) = (100 m)(√3)/2
kite height = 50√3 m ≈ 86.6 m
