Calculate the unit rate for Machine A and Machine B. Determine which is the greater rate.
Damm [24]

Answer:

Machine B

Step-by-step explanation:

Since, Machine A covers \frac{5}{8} square feet in \frac{1}{4} hours,

Rate at which the Machine A is covering = \frac{\frac{5}{8}}{\frac{1}{4}}

                                                                    = \frac{5}{8}\times \frac{4}{1}

                                                                    = 2.5 square feet per hour

Machine B covers \frac{2}{3} square feet in \frac{1}{5} hours,

Rate at which the Machine B is covering = \frac{\frac{2}{3}}{\frac{1}{5}}

                                                                    = \frac{2}{3}\times \frac{5}{1}

                                                                    = \frac{10}{3}

                                                                    = 3.33 square feet per hour

Therefore, Rate of Machine B is greater.

The coordinates of Point S are (2/5, 9 1/8). The coordinates of Point T are (-5 7/10, 9 1/8). What is the distance between Point
m_a_m_a [10]

something noteworthy, the y-coordinate for each point is the same, 9⅛, that means is a horizontal line, over which the x-coordinates are at, so since it's a horizontal line, all we need to do is find, what's the distance between \bf \frac{2}{5}\textit{ and }-5\frac{7}{10}

of course, let's firstly convert the mixed fraction to improper fraction and then check their difference.

\bf \stackrel{mixed}{5\frac{7}{10}}\implies \cfrac{5\cdot 10+7}{10}\implies \stackrel{improper}{\cfrac{57}{10}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{2}{5}-\left[-\cfrac{57}{10} \right]\implies \cfrac{2}{5}+\cfrac{57}{10}\implies \stackrel{\textit{using the LCD of 10}}{\cfrac{(2)2+(1)57}{10}}\implies \cfrac{4+57}{10}\implies \cfrac{61}{10}\implies 6\frac{1}{10}

28.5 g of iron shot is added to a graduated cylinder containing 45.50 mL of water. the water level rises to the 49.10 mL mark. F
Alika [10]
Density=mass/volume.
1) we have to calculate the iron volume in liters.
iron volume=second level - first level=49.10 ml-45.50 ml=3.6 ml
3.6 ml=3.6 ml(1 liter / 1000 ml)=0.0036 liters 

2) we calculate the mass iron in kg.
28.5 g=28.5 g(1 kg /1000 g)=0.0285 kg.
2) we calculate the density of iron.
density=0.0285 kg / 0.0036 liters=7.92 kg/L

7.92 kg/l=7.92 kg/L(1000 g/1Kg)(1000 cm³/1 L)=7.92 g/cm³.

answer: From this information the Iron density is 7.92 Kg/L or  7.92 g/cm³.
