Look at the example problem. Explain how you know 1 5/8 is little greater than 1 1/2.

natita [175]

Convert the fractions so both fractions have the same denominator. 1 1/2 is equal to 1 4/8 (1/2 * 4/4= 4/8). 1 4/8 is smaller than 1 5/8.

Jada made 6 cups of blueberry jam and divided the Jam in 4 containers. How much jam went in each container

Blizzard [7]

$1\frac{1}{2}$ cups of blueberry jam went in each container.

Step-by-step explanation:

Given,

Jada made blueberry jam = 6 cups

Number of containers = 4 containers

Jam in one container = $\frac{Cups\ of\ blurberry\ jam\ made}{Number\ of\ containers}$

Jam in one container = $\frac{6}{4}$

Jam in one container = $\frac{3}{2} = 1\frac{1}{2}$

$1\frac{1}{2}$ cups of blueberry jam went in each container.

I built a storage shed in the shape of a rectangular box on a square base. The material that I used for the base cost $4 per squ

Jobisdone [24]

Answer:

$\frac{a(450-8a^2)}{4}$

is the volume in terms of side a

Step-by-step explanation:

Given that you I built a storage shed in the shape of a rectangular box on a square base. The material that I used for the base cost $4 per square foot, the material for the roof cost $2 per square foot, and the material for the sides cost $2.50 per square foot; and I spent $450 altogether on material for the shed.

Let a be the side of square and h be the height

Total cost of materials = cost for floor + cost for roof + cost for sides

= area of floor (4) + lateral area (2.50)+roof area (2)

$=4a^2+4ah+4a^2\\=8a^2+4ah = 450$ $h = \frac{450-8a^2}{4a}$

Now coming to volume

Volume = V = lbh = $a^2 h\\= a^2*\frac{450-8a^2}{4a} \\=\frac{a(450-8a^2)}{4}$
