Jonathan has 3/4 pound of grapes. How many 1/8 pound servings can he make from his grapes.
pentagon [3]
6 servings. 1/8 +1/8 is 2/8 or 1/4 of a pound. Meaning that after 2 serving we still have only 1/4 of the amount of grapes leaving us with 2/4 more. So we would need 4 more 1/8’s making it a total of 6 servings. 1/8+1/8+1/8+1/8+1/8+1/8=6/8 or simplified 3/4.

How can polygons be considered a subcategory of two-dimensional figures? PLEASE HELP THIS IS DUE TOMORROW!!!!!!!!!
gregori [183]
Two-dimensional figures are one category and polygons are a separate category that falls under two-dimensional because 2D(two dimensional) figures are figures that do not have a volume so they are flat. Polygons are flat 2D shapes that have straight lines and all lines are closed, meaning that they don't have any disconnected lines. Polygons are a subcategory of 2D figures because they carry all traits of 2D figures but also have special ones of their own. Examples of polygons are squares, rectangles, and triangles. Examples of nonpolygons but still are 2D figures are circles, ovals, and any other flat shape.

At a greengrocer, two bananas and one apple cost ?1.16 and one banana and one apple cost ?0.71. How much does one apple cost?
Blababa [14]

Answer

Find out the how much does one apple cost .

To prove

Let us assume that the number of bananas be x .

Let us assume that the number of apples be y .

As given

At a greengrocer, two bananas and one apple cost $1.16 .

Than the equation becomes

2x + y = 1.16

one banana and one apple cost $0.71.

Than the equation becomes

x + y = 0.71

Subtracting x + y = 0.71 from 2x + y = 1.16

2x - x + y - y = 1.16 - 0.71

x = 0.45

Put in the equation x + y = 0.71

0.45 + y = 0.71

y = 0.71 - 0.45

y = $0.26

Therefore the cost of the one apple is  $0.26 .
