Mathematics
1 answer:
uysha [10]3 years ago
6 0

Answer:

Reduced Fraction :

\frac{ - 63}{8}

Decimal : -7.875

Step-by-step explanation:

1. Put both fractions in improper form

\frac{( - 3 \times 2)  -  1}{2}  =  \frac{ - 7}{2}

\frac{4}{9}  =  \frac{4}{9}

2. Multiply -7/2 by the reciprocal of 4/9 to get answer

<em>Concept</em><em> </em><em>:</em><em> </em>

<em>\frac{ \frac{1}{5} }{ \frac{1}{3} }  = ( \frac{1}{5}  \times  \frac{3}{1} )</em>

<em>\frac{ - 7}{2}   \times  \frac{9}{4} =  \frac{ - 63}{8}</em>

A typical sugar cube has an edge length of 1.00 cm. Imagine you have a cubical box that contains a mole of sugar cubes, perfectl
alisha [4.7K]

Answer:

844368.7 m

Step-by-step explanation:

We are given that a typical sugar cube has an edge length of 1.00 cm.

We have to find the edge length of the box in meters.

Edge length of sugar cube=1 cm =10^{-2}m (1 cm=\frac{1}{100}m)

Volume of a sugar cube=side\times side\time side=(10^{-2})^3=10^{-6}m^3

1 mole of sugar=6.02\times 10^{23}units

Volume of 1 unit=10^{-6} m^3

Volume of 6.02\times 10^{23} units=6.02\times10^{23}\times 10^{-6}=6.02\times 10^{17} m^3

Volume of box=1 mole of sugar=6.02\times 10^{17} m^3

Edge length of box=\sqrt[3]{6.02\times 10^{17}}=844368.7 m

Q1. An airplane flies with a constant speed of 600 miles per hour. How far can it travel in 3 1/2 hours?
Dahasolnce [82]

Answer:

Q1. 1050 miles

Q2. 1h 30m

Step-by-step explanation:

Q1. 1h = 300 miles

3\frac{1}{2}h = 3.5 × 300 miles

     = 1050 miles

Q2. 68km = 1h

102km = \frac{102}{68} × 1h

           = 1.5h

           = 1h 30m
