Maya says that value of the 6 in 0.006 is 1/10 of the value of the 6 in 0.6 . Is she correct? Explain

Nikolay [14]

Answer:

Maya is NOT correct as

$\frac{1}{1000}$ is 1/100 of the value $\frac{1}{10}$

Step-by-step explanation:

The value of 6 in 0.006 = $\frac{1}{1000}$

Also, the value of 6 in 0.6 = $\frac{1}{10}$

But, $\frac{1}{1000}$ is not 1/10 of the value $\frac{1}{10}$

as 1/10 of the value $\frac{1}{10}$ = $\frac{1}{100}$

Hence,Maya is NOT correct.

$\frac{1}{1000}$ is 1/100 of the value $\frac{1}{10}$

Find the value of x:<br> (6x + 7) °<br> 65°<br> (y + 90°

Salsk061 [2.6K]

Step-by-step explanation:

65 + (y + 9) = 180 ---------- Sum of angles on a

straight line

y + 65 + 9 = 180

y + 74 = 180

y = 180 - 74 = 106

6x + 7 = y + 9 ----------- Alternate angles

But y = 106,

6x + 7 = 106 + 9

6x = 115 - 7

x = 108/6 = 18
