x=0.4 and y=0.6

Step-by-step explanation:

Given :

\frac{x}{2} +y=0.8\\x+2y=1.6.......(1)\\\frac{7}{x+y/2} =10\\\frac{7}{2x+y/2} =10\\\frac{7*2}{2x+y} =10\\\frac{14}{2x+y} =10\\14=10(2x+y)\\14=20x+10y.....(2)

A rectangular prism is packed with cubes that measure 1/4 inch on each side. What is the volume, in cubic inches, of the rectang
Vladimir79 [104]

V = n X V(cube)

<u>Explanation:</u>

Given:

Side of the cube,a = \frac{1}{4}

Volume of the cube = a³

So, the volume of the cube, V is

V(cube) = (\frac{1}{4})^3

V(cube) = \frac{1}{64}

Let the number of cubes be n

Let V be the volume of the rectangular prism

Volume of rectangular prism = number of cubes X volume of cubes

V = n X V(cube)

If the number of cubes are known then substitute the value in the above given formula.

Grace and her children went into a grocery store and where they sell bananas for $0.50 each and mangos for $0.75 each. Grace has
nlexa [21]

Answer:

Grace could buy 1 or 2 bananas and not more than that and hence she cannot make the total count of fruits tleast 13.

Step-by-step explanation:

Cost of 1 banana = $0.5

Cost of 1 mango = $0.75

Total money Grace  has = $7.25

Grace has decided to buy 8 mangoes costing = 8 \times 0.75

                                                                             = $6

Grace has to buy a minimum of 13 mangoes and bananas altogether.

After Grace buy 8 mangoes , money remaining with her = 7.25 - 6

                                                                                              = $1.25

With the remaining money she has to buy bananas which cost her $0.5 each.

With $1.25 she can buy a maximum of 2 bananas only and the total number of fruits equals 10.

Hence it is not possible to buy 13 fruits altogether.
