HELP ME NOW FOR BRAINLEST!!!!!!1

Answer:

$84\frac{5}{9}$ ↔ $45\frac{2}{9}+39\frac{3}{9}$

$6\frac{2}{9}$ ↔ $-24\frac{5}{9} + 30\frac{7}{9}$

$-23.24$ ↔ $28.98+(-52.22)$

$131.87$ ↔ $56.7+75.12$

Step-by-step explanation:

$84\frac{5}{9}$ and $45\frac{2}{9}+39\frac{3}{9}$

Convert $84\frac{5}{9}$ to an improper fraction.

To write 84 as a fraction with a common denominator, multiply by $\frac{9}{9}$

Combine the numerators over the common denominator.

$\frac{84*9+5}{9}$

$\frac{756+ 5}{9}$

$\frac{761}{9}$ = $45\frac{2}{9}+39\frac{3}{9}$

covert $45\frac{2}{9}$ to an improper fraction

Combine the numerators over the common denominator.

$\frac{761}{9}$ = $\frac{45*9+2}{9}$ + $39\frac{3}{9}$

$\frac{761}{9}$ = $\frac{407}{9}$ + $39\frac{3}{9}$

covert $39\frac{3}{9}$ to an improper fraction

Combine the numerators over the common denominator.

$\frac{761}{9}$ = $\frac{407}{9}$ + $\frac{39*9+3}{9}$

$\frac{761}{9}$ = $\frac{407}{9}$ + $\frac{354}{9}$ → $\frac{407+354}{9}$

$\frac{761}{9}$ = $\frac{761}{9}$

therefore the statement $84\frac{5}{9}$ = $45\frac{2}{9}+39\frac{3}{9}$ is true

$6\frac{2}{9}$ and $-24\frac{5}{9} + 30\frac{7}{9}$

Convert $6\frac{2}{9}$ to an improper fraction.

To write 6 as a fraction with a common denominator, multiply by $\frac{9}{9}$

$\frac{6*9}{9} +\frac{2}{9}$ → $\frac{54+2}{9}$ → $\frac{56}{9}$

Convert $-24\frac{5}{9}$ and $30\frac{7}{9}$ an improper fraction

$-24\frac{5}{9}$ → $-(\frac{24*9}{9} + \frac{5}{9} )$ → $-\frac{24*9+5}{9}$ → $-\frac{221}{9}$

$30\frac{7}{9}$ → $\frac{30*9}{9} +\frac{7}{9}$ → $\frac{30*9+7}{9}$ → $\frac{277}{9}$

$\frac{56}{9}$ = $-\frac{221}{9}$ + $\frac{277}{9}$ →

$\frac{56}{9}$ = $\frac{56}{9}$

therefore the statement $6\frac{2}{9}$ = $-24\frac{5}{9} + 30\frac{7}{9}$ is true

$28.98+(-52.22)$ and $-23.24$

$28.98 - 52.22$ → $-23.24$

$-23.24$ = $-23.24$

therefore the statement $28.98+(-52.22)$ = $-23.24$ is true

$131.87$ and $56.7+75.12$

$56.7+75.12$ → $131.872$

$131.87$ ≠ $131.872$

therefore the statement $131.87$ = $56.7+75.12$ is False

The cover of a soccer ball consists of interlocking regular pentagons and regular hexagons. Why can't they be interlocked in thi

FinnZ [79.3K]

Answer: Because of gaps between the vertex of Pentagons and hexagon.

Step-by-step explanation:

The Pentagon has 5 sides and 5 vertex angles. While hexagon has 6 sides and six vertex angles

The sum of the angle of polygon is equal to ( n - 2 )180

Sum of the angle of a Pentagon will be: (5 - 2)×180 = 540

Each vertex angle of a Pentagon = 540/5 = 108

Sum of the angle of hexagon will be: (6 - 2)×180 = 720

Each vertex angle of a hexagon =

720/6 = 120

To interlock Pentagon and hexagon, the sum of the combination of vertex angles of both must be equal to 360 ( sum of the angles at a point = 360)

Since there is no number of combinations that can be equal to 360, there will surely be a gap.
