Answer:

Dimension of a Rectangular Box = 4 m × 3 m

Dimension of Second Rectangular box =5 m × 3m

→Mulch should be added to these two rectangular boxes having height 10 cm=0.01 m.Because 1 meter=100 cm.

Volume of 3 Cuboids having dimension , 4m × 3m × 0.01 m

           =3 ×Length × Breadth × Height

           =3× 4m × 3m × 0.01 m

           =0.36 m³

Volume of 2 Cuboids having dimension , 5m × 3m × 0.01 m

          =2× 5m × 3m × 0.01 m

           = 0.30 m³

Total volume or Amount of the Mulch that is to be added to Rectangular Boxes

                   =0.36 m³ +0.30 m³

                 =0.66 m³

HELP PLEASE!!!!
kumpel [21]

Answer:

The rational numbers are \frac{11}{3}, 6.25, 0.01045,\sqrt{\frac{16}{81}},0.\bar{42} and the irrational functions are \sqrt{48},\sqrt{\frac{3}{16}}.

Step-by-step explanation:

A rational number can be expressed in the form of \frac{p}{q}, where p and q are integers and q is not equal to 0. For example 2,3.5,\frac{2}{5},....

An irrational function can not be expressed in the form of \frac{p}{q}, where p and q are integers and q is not equal to 0. For example \sqrt{2},\sqrt{3},\sqrt{5},....

If any number is multiplied by a irrational number then the resultant number is an irrational number.

By the above definition we can conclude that:

The number \frac{11}{3} is a rational number.

\sqrt{48}=\sqrt{16\times 3}=4\sqrt{3}

Therefore \sqrt{48} is an irrational number.

6.25=\frac{625}{100}=\frac{25}{4}

Therefore 6.25 is a rational number.

0.01045=\frac{1045}{100000}=\frac{209}{20000}

Therefore 0.01045 is a rational number.

\sqrt{\frac{16}{81}}=\frac{4}{9}

The number \frac{16}{81} is a rational number.

\sqrt{\frac{3}{16}}=\frac{\sqrt{3}}{4}

The number \frac{3}{14} is an irrational number.

0.\bar{42}=\frac{42}{99}

Therefore 0.\bar{42} is an irrational number. The numbers with recursive bar are always rational numbers.

Gracie has 5 quarters 4 nickels and 1 penny in her pocket. She selects a coin at random. What is the probability of selecting a
irina1246 [14]

Answer:

2/5

Step-by-step explanation:

5+4+1 = 10. If you have 4 nickels out of 10 coins, it means there is a 4/10 chance of selecting one, but to simplify, 2 is the greatest common factor, so you would divide each number.

4/2 = 2.

10/2 = 5.

The answer is 2/5.
