Which number is equivalent to 0.45? line over .45

Mathematics
1 answer:
Sergeeva-Olga [200]2 years ago
6 0

Answer:

\frac{5}{11}

Step-by-step explanation:

The line over 45 indicates 45 is being repeated, that is

0.4545....

Create 2 equations with the repeating values after the decimal point

let x = 0.4545..... → (1) ( multiply both sides by 100 )

100x = 45.4545..... → (2)

Subtract (1) from (2) eliminating the repeating decimal

99x = 45 ( divide both sides by 99 )

x = \frac{45}{99} = \frac{5}{11}

Thus 0.4545... = \frac{5}{11}

Answer:

(x, y ) → (x + 11, y - 11 )

Step-by-step explanation:

Consider the point U and its image U'

U (- 9, 1 ) → U' (2, - 10 )

This represents a shift of 2 - (- 9) = 2 + 9 = + 11 → in the x- direction and

- 10 - 1 = - 11 ↓ in the y- direction

This can be shown in the translation rule

(x, y ) → (x + 11, y - 11 )

A cleaner recommends mixing 1½ cup of cleaner for every 12 cups of water. What is the ratio of cleaner to water in simplest form
Pavlova-9 [17]
1.5 cleaner / 12 cups of water
or
1.5 cleaner : 12 cups of water
to reduce this ratio of 1.5:12, we need to divide both by the same number

1.5 divided by 1.5 is 1
12 divided by 1.5 is 8

So the ratio of cleaner to water is 1:8 in its simplest form or 1 part cleaner to 8 parts water.

Hope this helps!!  :)

Find f(g(x)) and g(f(x)) for the following functions<br><br> f(x) = 2x<br><br> g(x) = x + 5
Helga [31]
F(x)=2x
G(x)=x+5
Now
F(g(x))=2(x+5)
=2x+10
G(f(x))=2x+5
