0.4 divided by 0.08 show your work
Sergeeva-Olga [200]

Answer:

5

Step-by-step explanation:

Since we have not instructed to follow any kind of rule dividing, we can write in any form. Let's calculate it using fraction

0.4:0.08=\frac{0.4}{0.08}

We can multiply both the nominator and denominator with 100

\frac{0.4}{0.08}=\frac{40}{8}=5

The answer is 5.


We can also solve it as a division of fractions:

\frac{4}{10} : \frac{8}{100} = \frac{4}{10} * \frac{100}{8} = \frac{10}{2} = 5

Identify the slope of the line shown in the graph below: Graph of a vertical line with an x intercept of 4
lions [1.4K]
For this case we have the following line:
 x = 4
 The first thing you should know is that the slope of the line is given by:
 m = (y2-y1) / (x2-x1)
 In this case:
 x2 = x1
 Thus,
 The slope is:
 m = (y2-y1) / (0)
 m = infinity
 Answer:
 
The slope of the line is:
 
m = infinity

Angelica painted 1/20 of her bedroom walls in 1/2 an hour. How long will it take Angelica to paint her whole bedroom?
julsineya [31]

Angelica would have painted the bedroom in 20 hours if every hour she painted 1/20. But she doesn't paint 1/20 of a room per hour but rather 30 minutes. That means it will take her 10 hours to paint the whole room.

Hope this helps.

39 is what percent of 96
ra1l [238]

Answer:

40.625%

Step-by-step explanation:

This is a very simple question.

We have to understand converting word equations to algebraic ones.

"is" means "="

"of" means "*"

So, we can write:

39 = what percent * 96

Now, we let "what percent" be "p" and solve the equation for p:

39 = P * 96

So,

39 = P * 96\\39=96P\\P=\frac{39}{96}\\P=0.40625

Converting this decimal to percentage means multiplying by 100, so we have:

0.40625 * 100

= 40.625%
