Mitch bought four cookbooks and one novel for a total of $68.75. Each cookbook cost the same price. Thenovel cost $7 dollars less than a cookbook.How much did each cookbook cost?

Answer:

$13,793

Step-by-step explanation:

Kate purchased a car for $23,000. It will depreciate by a rate of 12% a year. What is the value of the car in 4 years. *

The formula for Depreciation rate =

y = a(1 - r) ^t

Where

y = Value of the car after t years

a = Initial value of the car = $23,000

t= time in years = 4 years

r = Depreciation rate = 12% = 0.12)

y = $23000 (1 - 0.12)⁴

y = $13792.99328

Approximately = $13,793:

Answer:

85 people

Step-by-step explanation:

in a country , if 17 out of every 20 people are literate, then;

17 literate = 20 people

To get the number of literate people in 100

x literate = 100 people

Divide both expressions

17/x = 20/100

Cross multiply

20x = 17 * 100

x = 1700/20

x = 85

Hence 85 people are literate out of 100 people

The correct answer is graph Y

Step-by-step explanation:

Just took the test on Plato

The graph which represents function [tex]f(x)=\sqrt{x-1}[/tex] is the one which is given in option [tex](c)[/tex].

Graph a diagram in which a line or a curve shows the relationship between two quantities, measurements

We have,

[tex]f(x)=\sqrt{x-1}[/tex]

For the function to be defined the numerator must not be equals to zero and there must be a positive value inside the square root.

First we will find domain for  [tex]y=\sqrt{x-1}[/tex]  now a list of [tex]x[/tex]  values can be picked.

[tex]x-1 > 0[/tex]

[tex]x > 1[/tex]

Now, Graph using the end point and a few selected points.

       1.41[tex]\left\begin{array}{ccc}x & y\\1&0\\2&1\\3 &1.41\end{array}\right[/tex]

Now, when we will plot these points on graph we will get the same raph as given in option [tex](c)[/tex].

Hence, we can say that The graph which represents function [tex]f(x)=\sqrt{x-1}[/tex] is the one which is given in option [tex](c)[/tex].

The amount of money she put in the account is $22.

In simple terms, the unitary method is used to find the price of a single unit from a given multiple.

Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.

We are given that Vickie earned $6 an hour while working 11 hours over the weekend she put one third of what she and in a savings account

Therefore,

$6 x 11 hours = $66

Now we know that 1/3 of $66 = $22

Hence, She put $22 into the account.

Answer: 48

Step-by-step explanation: just got it right on ap3x

Answer:

$25.50

5.75x-3.25

Step-by-step explanation:

one pound equals 5.75 so to get five pounds multiply it by 5

5.75×5=28.75

then subtract the 3.25 for the coupon

28.75-3.25=25.5

for equation 5.75 is your slope which you would multiply by your x to get the total cost before the coupon and 3.25 is your y intercept that you would subtract to get your total after using the coupon

Answer:

$25.50

Step-by-step explanation:

Find out how much it costs for 5 pounds of coffee, the coupon will be added into the solution later.

1 pound of coffee = $5.75

5 pounds of coffee = $5.75 x 5 = $28.75

So 5 pounds of coffee without the coupon costs $28.75.

Let's add the coupon into the working now.

5 pounds of coffee (with coupon) = $28.75 - $3.25 = $25.50

t = 6

Step-by-step explanation:

30 + 6t = 11t

Subtract -6 from both sides

30 - 6t + 6t = 11t - 6t

-6 + 6 = 0

11 - 6 = 5

30 = 5t

Divide 5 by both sides

30/5 = 5t/5

t = 6

2123.992in^2

Step-by-step explanation:

Area of the pizza can be determined using the expression below

Area= (π d^2)/4

Given,

Diameter=52-inch

If we substitute we have

Area= [ π × (52)^2 ]/4

=8495.968/4

=2123.992in^2

Hence, the area of the pizza to the nearest square inch is 2123.992in^2

Answer: The distance between points A and B is 32 units.

Step-by-step explanation:

The general equation for a line in slope-intercept form is:

y = a*x +b

Where a is the slope, and b is the y-intercept.

We know that two lines are parallel if the lines have the same slope and different y-intercept.

Now, in this case we have the line:

5*x + 4*y = 16

We can rewrite this in slope-intecept form if we isolate the "y" in the left side:

4*y = -5*x + 16

y = (-5/4)*x + 16/4

y = (-5/4)*x+ 4

The slope is (-5/4) and the y-intercept is 4.

We know that line L₂ is parallel to this line, then this line will also have a slope equal to (-5/4) and a y-intercept equal to c.

y = (-5/4)*x + c

And we know that this line passes through the point (8, 15)

This means that when x = 8, the value of y must be 15.

We could just replace these two values in the above equation to find the value of c.

15 = (-5/4)*8 + c

15 + (5/4)*8 = c = 25

Then the line L₂ is:

y = (-5/4)*x + 25.

Now, we know that this line passes the x-axis at the point A.

The line will pass through the x-axis when y = 0, then we need to find the value of x such that y = 0.

0 = (-5/4)*x + 25

(5/4)*x = 25

x = 25/(5/4) = 20

Then point A is the point (20, 0)

And point B is when the line passes through the y-axis, this is when x = 0.

y = (-5/4)*0 + 25

y = 25

Then point B is the point (0, 25)

Now we want to find the distance between points A and B, which is equal to the distance between points (20, 0) and (0, 25).

When we have two points (a, b) and (c, d), the distance between them is:

distance = √( (a - c)^2 + (b - d)^2)

In this case, the distance between (20, 0) and (0, 25) is:

distance = √( (20 - 0)^2 + (0 -25)^2) =  32

The distance between points A and B is 32 units.

Answer:

7

Step-by-step explanation:

Since this is a right triangle, we are going to use pythagorean theorem

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

Where a and b are the legs and c are the hypotenuse.

Let plug it in.

[tex] {6}^{2} + {y}^{2} = { \sqrt{85} }^{2} [/tex]

[tex]36 + {y}^{2} = 85[/tex]

[tex]y {}^{2} = 49[/tex]

[tex]y = \sqrt{49 } [/tex]

[tex]y = 7[/tex]

Given that,

The points are (4,4) and (8,3)

To find,

The slope of the line.

Solution,

The slope of a line is given by the formula as follows :

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Put x₁ = 4, y₁ = 4, x₂ = 8 and y₂ = 3

[tex]m=\dfrac{3-4}{8-4}\\\\=\dfrac{-1}{4}[/tex]

So, the slope of the line is [tex]\dfrac{-1}{4}[/tex].

Step-by-step explanation:

The decimal point moves to the right, because 10 to the power of 4 is 10,000.

The value of 0.45 x [tex]10^4[/tex] is 4500.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

0.45 x [tex]10^4[/tex]

= 45/100 x [tex]10^4[/tex]

= 45 x 10²

= 4500

Thus,

The value of the expression is 4500.
