Answer:
900 ≤ x ≤ 1000
Step-by-step explanation:
Given
Minimum = 900
Maximum = 1000
Required
Write and solve a compound inequality
Represent the number of seashells with x.
To solve this, we first consider the minimum.
The relationship between x and the minimum is:
x ≥ minimum
This gives
x ≥ 900
Then, we consider the maximum.
This is represented as:
x ≤ maximum
x ≤ 1000
The two inequalities are:
x ≥ 900 and x ≤ 1000
This can be rewritten as:
900 ≤ x and x ≤ 1000
Combine both:
900 ≤ x ≤ 1000
Answer:
<em>17 inches </em>
Step-by-step explanation:
c² = a² + b²
c = √(225 + 64) = √289 = <em>17 inches</em>

Step-by-step explanation:
Answer:
135 degrees
Step-by-step explanation:
2π radians is the central angle of a full circle, so 2π radians is 360 degrees.
That means that π radians = 180 degrees.
3π/4 radians * (180 degrees)/(π radians) = 135 degrees
For 10 miles, he takes = 85 min
then, 1 mile = 85/10 min.
Now, for 8 miles, it would be 85*8/10 = 68 minutes
