Writing in Math. Explain how the digit 7 can have different values.

ella [17]

The value of a number is for example 7, 70 (but also 8, 80, etc). 7 can refer to the value of seven if it's on its own or if it's on the rightmost position, but in the number 75, seven refers to the value of 70. The same digit can have different values in a place value system where the value represented by a digit depends on its position.

Can someone please help

Gnom [1K]

Answer:

<ABC = 70 degrees

<AMC = 60 degrees

< AMB = 60 degrees

Step-by-step explanation:

<ABC = 180-110 = 70 degrees

<AMC = 2x + 60 = 180

2x = 180 - 60

x = 120/2

x = 60

<AMB = 180/3 = 60

Answer:

r = sqrt(16/pi)

Step-by-step explanation:

Cylinder formula = r^2 x pi x height

176 pi/11pi = 16

16 = r^2 x pi

16/ pi = r^2

r = sqrt(16/pi)

Find two numbers if their ratio is 9:11 and their difference is 6. Not 27 and 33

meriva

Answer:

Sets of numbers are ( 27,33) and (-27, -33)

Explanation;

Let the numbers be a and b.

We have their ratio is 9:11

$\frac{a}{b} =\frac{9}{11} \\ \\11a=9b$

Their difference is 6

$\left | a- \right b|=7$

( a - b) = 6 or (b - a ) = 6

11a - 11 b = 66 or 11b - 11a = 66

9b - 11 b = 66 or 11b -9b = 66

-2b = 66 or 2b = 66

b = -33 or b = 33

if b = -33, a = -33 + 6 = -27

if b = 33, a = 33-6 =27

So, the sets of numbers are ( 27,33) and (-27, -33)
