Answer:

y = -3

Step-by-step explanation:

it crosses the y axis at -3. Also, it's horizontal so the slope is zero.

Given parameters:

Original selling price = $84

Discounted Selling price  = $72

Unknown:

Percentage discount = ?

Solution:

To find the percentage discount;

Discount = Original selling price  - Discounted selling price

               = $84 - $72

               = $12

Now,

  Percentage discount  = [tex]\frac{12}{84} x 100[/tex]   = 14.3%

The percentage discount is 14.3%

Answer:

Anna owes $3600 to the bank

Step-by-step explanation:

12/100 * 6000 = 720 * 5 years

= $3600

Hence Anna owes $3600 to the bank

Answer: n=6

Step-by-step explanation:

First you subtract 18 from both sides so that it become -1/2n^2=-18

Second divide both sides by -1/2 so it becomes -18/(-1/2)=n^2

Then you simplify and get n^2=36

Finally you find the square root of both side, and you get n=6

Answer:

  240 square feet

Step-by-step explanation:

The area of a composite figure can be found by adding the areas of its parts.

__

Extending the vertical line across the figure cuts off a rectangle on the left that is 18 ft long and 10 ft high. It cuts off a triangle on the right that has a base of 20 ft and a height of 24-18 = 6 ft.

The sum of the areas of these parts is ...

  rectangle area + triangle area

  = (10 ft)(18 ft) +1/2(20 ft)(6 ft) = 180 ft² +60 ft²

  = 240 ft² . . . . area of the figure

_____

Additional comment

You can see that this is the product of the height of the rectangle and the overall length of the figure. This means the smaller triangles that stick above or below the horizontal lines would fit exactly into the spaces at the tip of the arrow, filling in a 10 ft × 24 ft rectangle.

60 1/8

Step-by-step explanation:

6 1/2 * 9 1/4 =

= 481/8

= 60 1/8

Answer:

She took 28 shots, 7 shots would be the remaining 25% so you multiply it by 4 to get 100% or 7 × 4 = 28

missed shots = 7 = 25%             since 75% are successful

proportionality table

25% ...............7

100% ........... = 7 x 100% : 25% = 28

total = 28 shots

Answer:

0.8

Step-by-step explanation:

Find the mean of the list:

(0.2, 0.21, 0.17, 3.22, 0.2)

The mean of a list of numbers is given by:

(sum of elements)/(number of elements)

(sum of elements) = 0.2 + 0.21 + 0.17 + 3.22 + 0.2:

(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/(number of elements)

Counting, we see that the list has 5 elements:

(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/5

0.2 + 0.21 + 0.17 + 3.22 + 0.2 = 4:

4/5

4/5 = 0.8:

Answer:  0.8

Answer:

0.8

Step-by-step explanation:

The mean of the data set can be found by adding all terms together and dividing by the amount of terms there is. In this case, add all the numbers and divide by 5:

(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/5 =

(4)/5 = 0.8

0.8 is the mean for the given set.

if h(x) = [tex]x^{2} -5x+7[/tex] so the value of  [tex]\frac{1}{3}[/tex]× [tex]h(-8)[/tex] = [tex]\frac{111}{3}[/tex].

A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. The meanings of the word equation and its cognates in other languages can vary slightly. For instance, in French, an equation is defined as having one or more variables, whereas, in English, an equation is any well-formed formula that consists of two expressions linked by the equals sign.

Finding the values of the variables that result in equality is the first step in solving an equation with variables. The variables that must be included in the equation are also known as the unknown.

we have h(x) = [tex]x^{2} -5x+7[/tex]

So, substitute the value [tex]x=-8[/tex] in the equation,

h([tex]-8[/tex]) = [tex](-8)^{2} -5(-8)+7[/tex]

        = [tex]64+40+7[/tex]

        = [tex]111[/tex]

And now we shall multiply it with [tex]\frac{1}{3}[/tex],

we get, [tex]\frac{1}{3}[/tex]× [tex]h(-8)[/tex] = [tex]\frac{111}{3}[/tex]

Answer:

$2.40

Step-by-step explanation:

as five of artichokes caused $1, a dozen is the same number as 12, so use cross multiply and you will get the answer $2.40

cross multiply : 5 artichokes = $1

12 artichokes = x

5x = $1 x $12

5x = $12

x = 12/5

x = $2.40

Step-by-step explanation:

Answer: x=36

Assuming that O is the centre of the circle,

108+a+a=180(sum of the interior angles of a triangle is 180)

2a=180-108

2a=72

a=72÷2

a=36

a=x (angles in the same segment are equal)

Therefore x=36

Step-by-step explanation:

[tex]f(x)=2^x\\\\g(x)=x-4\\\\(f\circ g)(x)=f(g(x))=f(x-4)=2^{x-4}[/tex]

This means that the parent function, [tex]f(x)=2^x[/tex], will shift 4 units to the right along the x-axis, so this DOES NOT affect the range (nor the domain either). Thus,  [tex]y > 0[/tex] would be the range.
