Katrina drinks 0.5 gallons of water per day. which expression shows how to find the number of cups of water she drinks in a week? there are 16 cups in a gallon. × × × × × × × ×

Expression  Katrina drinks of water in 7 day = 8 *7 cups .

Step-by-step explanation:

Given  : Katrina drinks 0.5 gallons of water per day and There are 16 cups in a gallon.

To find : Which expression shows how to find the number of cups of water she drinks in a week.

Solution : We have given that

Katrina drinks of water per day = 0.5 galoons.

1 gallon  = 16 cup .

So,  Katrina drinks of water per day = 0.5 * 16 cups.

Katrina drinks of water per day = 8  cups.

1 week =  7 days .

Katrina drinks of water in 7 day = 8 *7 cups.

Katrina drinks of water in 7 day = 56  cups.

Therefore, Expression  Katrina drinks of water in 7 day = 8 *7 cups .

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
