What is the length of the line segment pq on the coordinate grid?

1) 20 units
2) 30 units
3) 40 units
4) 50 units

The length of the line segment PQ on the coordinate grid is 30 unit.

Step-by-step explanation:

Consider the provided graph.

The coordinate of the point P and Q are (-20,10) and (10,10) respectively.

In order to find the length of the line segment use the distance formula:

Now substitute the respective values in the above formula as shown:

Hence, the length of the line segment PQ on the coordinate grid is 30 unit.

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.

hi there!

question 1 answer: p/q can be terminating when q = 5^m * 2^n

question 2 answer: -1 and -1

question 3 answer: -4

question 4 answer: 5/12

hope this : )
