<span>Using the formula d=m/v, we first need to convert 5.0 and 45.0 to their SI unit equivilents. 5.0g is 0.005kg, 45.0cm^3 becomes 0.000045m^3.Therefore, the density of your cube is 0.005/0.000045=111.11 kg/m^3(5 s.f)</span>

Question 3 of 8. Step 1 of 1
natali 33 [55]

308 gallons of 7% and 77 gallons of 2% are needed to obtain the desired 385 gallons.

<h3><u>Combination</u></h3>

Since a dairy needs 385 gallons of milk containing 6% butterfat, to determine how many gallons each of milk containing 7% butterfat and milk containing 2% butterfat must be used to obtain the desired 385 gallons, the following calculation must be performed:

  • 385 x 0.06 = 23.1
  • 300 x 0.07 + 85 x 0.02 = 22.7
  • 310 x 0.07 + 75 x 0.02 = 23.2
  • 308 x 0.07 + 77 x 0.02 = 23.1

Therefore, 308 gallons of 7% and 77 gallons of 2% are needed to obtain the desired 385 gallons.

What is the result when 6x^3+25x^2+20x+46x
goldenfox [79]

Answer:

The answer to your question is 2x² - 29x + 26

Step-by-step explanation:

dividend =  6x³ - 25x² + 20x + 4

divisor    =  3x + 2

                             2x² - 29x + 26

               3x + 2    6x³ - 25x² + 20x + 4

                            -6x³ -   4x²  

                              0   - 29x² + 20x

                                   + 29x² + 58x

                                       0         78x + 4

                                                 -78x - 52

                                                    0   - 48

quotient =   2x² - 29x + 26

remainder = -48

Result =  2x² - 29x + 26 - 48/6x³ - 25x² + 20x + 4

Drag each volume of a prism to match a rectangular prism
Hunter-Best [27]

The volume of the rectangular prism with the dimensions given are as follows:

v = 72 inches³

v = 36 inches³

v =  80 inches³

v = 54 inches³

<h3>Volume of a rectangular prism</h3>
  • v = lwh

where

l = length

w = width

h = height

Therefore,

a.  

  • v = 4 × 3 × 6 = 72 inches³

b.

  • v = 6 × 3 × 2 = 36 inches³

c.

  • v = 4 × 5 × 4 = 80 inches³

d.

  • v = 2 × 9 × 3 = 54 inches³

Sean is driving to visit his friend in another state. In the first hour, he travels 1/5 of the total distance. Second hour he tr
astra-53 [7]

Answer:

The friends live 285 miles apart.

Step-by-step explanation:

Let total distance in miles Sean needs to cover to visit his friend be = x

On first hour distance traveled in miles is = \frac{1}{5}\ of\ the\ total\ distance = \frac{1}{5}.(x)=\frac{1}{5}x

Distance left to cover  after first hour = x-\frac{1}{5}x

On second hour distance traveled = 34 miles

Distance to still left to be covered = 194 miles

Total distance to be covered after first hour will be = 34\ miles+194\ miles = 228 miles

Thus, the equation can be given as:

⇒ x-\frac{1}{5}x=228

Multiplying each term with 5 to remove fractions.

⇒ 5x-5.\frac{1}{5}x=5\times228

⇒ 5x-x=5\times228

⇒ 4x=1140

Dividing both sides by 4.

⇒ \frac{4x}{4}=\frac{1140}{4}

∴ x=285

Thus, the friends live 285 miles apart.
