Answer:

60%

Step-by-step explanation:

18 out of 30 movies are adventure so we can vizualize this as

18/30 this giving us the decimal 0.60

Now to convert from a decimal to a percent just multiply by 100 or move the decimal to the right 2 decimal point.

0.60 x 100 = 60%

Answer:b

Step-by-step explanation:

Answer:

b

Step-by-step explanation:

Answer:

The zeros are:

[tex]x =4, x=2, x = 5[/tex]

Hence, option (B) is true.

Step-by-step explanation:

Given the expression

[tex]h\left(x\right)=\left(x-4\right)^2\left(x^2-7x+\:10\right)[/tex]

Let us determine the zeros of the function by putting h(x) = 0 and solving the expression

[tex]0=\left(x-4\right)^2\left(x^2-7x+10\right)[/tex]

switch sides

[tex]\left(x-4\right)^2\left(x^2-7x+10\right)=0[/tex]

as

[tex]x^2-7x+\:10=\left(x-2\right)\left(x-5\right)[/tex]

so

[tex]\left(x-4\right)^2\left(x-2\right)\left(x-5\right)=0[/tex]

Using the zero factor principle

so

[tex]x-4=0\quad \mathrm{or}\quad \:x-2=0\quad \mathrm{or}\quad \:x-5=0[/tex]

[tex]x =4, x=2, x = 5[/tex]

Thus, the zeros are:

[tex]x =4, x=2, x = 5[/tex]

It is clear that there are three zeros and all the zeros are distinct real numbers.

Therefore,

Hence, option (B) is true.

Answer:

[tex]\frac{612}{999}[/tex]

Step-by-step explanation:

To convert repeating decimals to fractions, you take the numbers that are repeating, in this case 612, and you see how many numbers are repeating. Here we have 3 numbers repeating and so you would divide 612 by 3 9's meaning 999. So 0.612 repeating is equal to [tex]\frac{612}{999}[/tex]. To make sure the answer is right, you can divide the numbers in a calculator to make sure you get the correct decimal.

Answer:

vertex = (- 10, - 10 )

Step-by-step explanation:

The equation of a quadratic in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

To obtain this form use the method of completing the square.

Given

h(x) = x² + 20x + 90

add/subtract ( half the coefficient of the x- term )²

h(x) = x² + 2(10)x + 100 - 100 + 90

      = (x + 10)² - 10 ← in vertex form

with (h, k ) = (- 10, - 10 )

Answer:

The blue box

Step-by-step explanation:

Youre talking about range which takes place on the y-axis (domain is the x-axis).

The top point is an open circle which indicates in the math world the parentheses and the bottom point 1 in a bracket as its a closed circle.

Answer:

4:18 6:27 8:36

Step-by-step explanation:

Answer:

1. False

2. False

3. True

Step-by-step explanation:

1. It fails the 'Vertical Line Test.' Draw a line through the center of the relation and see if the line passes through the graph more than once. It does, therefore it fails the test. Meaning it is not a function.

2. Domain (x) is all the x-values in the equation, the relation only contains the x-values x>0 and x<7 (0 - 7). Meaning it does not contain all real numbers.

3. The range (y) contains negative numbers because the relation is partially in the 4th quadrant, meaning it MUST contain a negative y-value.

Answer:

I think it roughly 66.67%

Step-by-step explanation:

sorry if I'm no help

The percent of questions she answered correctly is 80%.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Given;

Answer: 36 cm^3

Step-by-step explanation:

To solve this you multiply the length by the width by height (so 6x2x3) this is the same formula you use to solve volume for similar equations. 6x2x3 is 36 but you need to remember to add the unit of measurement and to cube it (^3). I hope this helps!!!!
