Answer:

36

Step-by-step explanation:

to find 100%, multiply 9 (25%) by 4 and get 36

25% of 36 is 9.

Important information:

We need to find the unknown number w.

25% of a number w is 9. So,

[tex]\dfrac{25}{100}w=9[/tex]

[tex]\dfrac{1}{4}w=9[/tex]

[tex]w=9\times 4[/tex]

[tex]w=36[/tex]

Thus, the value of the unknown number is 36.

Answer:

7.79

Step-by-step explanation:

A hundredth is the second number after the decimal. For example, in the number 100.234, the "3" would be the hundredth, the "2" would be the tenth, and the "4" would be the thousandth.

To round to the nearest hundredth, you have to look at the thousandth because when rounding, you look at the next number to decide whether to round up or down.

Since 8 is in the thousandth place in this question, and 8 is bigger than 5, you round up. So, you round the "8" in the hundredths place up to 9.

Therefore, you get 7.79.

Answer:

y= -⅕x -7

Step-by-step explanation:

The slope of a perpendicular line is the negative reciprocal of that of the given line.

That is, if the slope of the given line is m, then the slope of the perpendicular line is [tex] - \frac{1}{m} [/tex].

Another way to remember it is that the product of the slopes of two perpendicular lines is -1.

Given equation: y= 5x +9

This equation is in the slope-intercept form, thus its slope is the coefficient of x.

Slope= 5

Slope of perpendicular line= -⅕

Hence we should look for an equation with -⅕ as the coefficient of x, since all the options given are in slope-intercept form.

Thus, y= -⅕x -7 is the correct option.

Step-by-step explanation:

it has a repeating domain so it can not be a function

0,−1,2,1,0 has two values corresponding to a range of functions so it will not form a function so option (C) will be correct.

A function's range is the set of all values that the function accepts, and its domain is the set of all values for which the function is defined.

The domain is for the independent variable while the range is for the dependent variable.

For example f(x) = x²

Now if we put x = 1 then it is called as domain variable while the value of functin at x = 1 its that f(1) = 1 called range variable.

To be a relation a function for every single unique input there must be single unique output.

Since the interval 0,−1,2,1,0 has 2 inputs for single output so it will not form an function.

Hence "0,−1,2,1,0 has two values corresponding to a range of functions so it will not form a function".

Answer:

Step-by-step explanation:

a) The relative minimum of the function from the graph is -18 at x=0.

b) The graph ends with two arrows which means it continues from there indefinitely. So the function increases from x equal to negative infinity to -2 and then from 0 to +2.

Answer:

  3/4 square units

Step-by-step explanation:

When linear dimensions of similar figures are related by a factor of k, their areas are related by a factor of k².

For an original figure of area 12, each image figure dilated by a factor of k will have an area of 12k².

For k=1/4, the area is ...

  12(1/4)² = 12/16 = 3/4 . . . . square units

_____

Additional comment

Their volumes are related by a factor of k³. It can help you understand if you think about the area and volume formulas:

  A = LW

  A' = L'W' = (kL)(kW) = k²·LW = k²·A

Similarly ...

  V = LWH

  V' = L'W'H' = (kL)(kW)(kH) = k³·LWH = k³·V
