Answer:

Step-by-step explanation:

MORE THEN IMPLIES + SIGN. SO NO

GREATER THAN IMPLIES AN INEQUALITY. SO YES

BELOW ALSO IMPLIES AN INEQUALITY BUT THE SIGN IS > NOT <. SO NO

ABOVE EIGHTEEN CAN WORK (NEVER HEARD IT PHRASED THIS WAY). SO YES

LESS THAN EIGHTEEN IS NO BECAUSE WE WANT GREATER THEN EIGHTEEN. SO NO

Answer:

The sum of one-half and a number is more than eighteen.

The sum of one-half and a number is greater than eighteen.

The sum of one-half and a number is above eighteen.

Step-by-step explanation:

An inequality is when two expressions are not equal and the relationship could be greater than or less than. In this case, the sign > indicates that the expression 1/2+k is higher than 18. So, the phrases that can be used to represent this are the ones that contain the words more than, greater than and above that convey the meaning that the sum of one-half and a number is higher than 18.

Answer:

44 degrees

Step-by-step explanation:

angle c = 90 degrees

angle a = 46 degrees

the measure of all sides on a triangle is 180

so to solve for the other side we can do this equation...

180 - (90 + 46) = 44

hope this helped, mark as brainliest pls

Answer: 10 miles

Explanation:

We define the following resting spots

A = resting spot whose coordinate is (2,2)
B = resting spot whose coordinate is (2,4)
C = resting spot whose coordinate is (5,2)
D = resting spot whose coordinate is (5,4)

If you plot A, B, C, D, you will notice that

(Perimeter of the trail) = 2[(distance from A to C) + (distance from A to B)]

Note that A and C have the same y-coordinates (second number in their ordered pairs), so the distance from A to C is computed as the difference of their x-coordinates (first number in their ordered pairs). Thus,

(distance from A to C) = 5 - 2 = 3

Moreover, A and B have the same x-coordinates and so we compute the distance from A to B as the difference of their y-coordinates. Then,

(distance from A to B) = 4 - 2 = 2

Hence,

(Perimeter of the trail) = 2[(distance from A to C) + (distance from A to B)]
= 2[2 + 3]
= 2(5)
(Perimeter of the trail) = 10 miles
