Answer: 2 < x < 16
The triangle inequality theorem says that if we have a triangle with sides a,b,c then
b-a < c < b+a
with b being longer than 'a'
In this case, a = 7 and b = 9 and c = x
so we have
b-a < c < b+a
9-7 < c < 9+7 .... replace a with 7, replace b with 9
2 < c < 16
2 < x < 16 .... replace c with x
So x can be any number between 2 and 16. The value of x cannot be equal to 2. Also, x cannot be equal to 16 either.
A ratio is like a fraction, so since you are provided with the numbers its easy to put it into a ratio
depth is 3.8km
width is 7600km
ratio is 3.8:7600
89% I.e C should be the answer I hope it helps you . it should be
4+5=9
4÷9×200=88.8% approximately 89%
Answer:
4
Step by step:
The square root of 16 is 4. To check, multiply 4 on itself (4x4) to see if the answer is 16.
1000 miles would be 5,280,000 feet.
If one mile is 5,280 feet, multiplying this by 1000 will give you the distance of 1000 miles. You can also do it quickly by adding the zeroes (in the case of 1000 there are 3) to 52800 to indicate multiplication by three places.
