Complete question:

A book shop sold fiction books and cartoon books at a ratio of 3:5. Then, it sold four times as many fiction books and 40% more cartoon books. As a result, it sold 800 more fiction books than cartoon books. How many fiction and cartoon books were sold altogether in the end?

Answer:

3040

Step-by-step explanation:

Given the following :

Sales ratio = 3:5 (fiction : cartoon)

Let total number of books sold = x

Fiction books = 3x

Cartoon books = 5x

Four times as many fiction books = 4 × fiction books = 4*(3x) = 12x - - - (1)

40% more cartoon books = 40/100 = 0.4

5x(1.40) = 7x - - - (2)

As a result, 800 more fiction books than cartoon :

Fiction - cartoon = 800

12x - 7x = 800

5x = 800

x = 160

Substitute x into (1) and (2)

Fiction books : 12(160) = 1920

Cartoon books : 7(160) = 1120

1920 + 1120 = 3,040

Answer:

h(-67) = 3158

Step-by-step explanation:

Simply plug in -67 for x:

h(-67) = -49(-67) - 125

h(-67) = 3283 - 125

h(-67) = 3158

Answer: h(-67) = 3158

Step-by-step explanation:

-49(-67)-125

3283-125

3158

Answer:

a · b  = 28 units

Step-by-step explanation:

Given vectors

a = (-5, 1/2)

b = (-5, 6)

The scalar or dot product of the two vectors, given by a · b is

a · b  = (-5, 1/2) · (-5, 6)

To solve this, multiply the first term in a with the first term in b and add the result to the product of the second term in a and the second term in b. i.e

a · b  = (-5 x -5) +  (1/2 x 6)

a · b  = 25 + 3

a · b  = 28

Therefore, the dot product of a and b is

a · b  = 28 units

Answer:

B

Radius of circle = 14ft

We have to find the area of circle[tex].[/tex]

Area of circle of radius R is given by

⇒ A = π × R²

⇒ A = π × (14ft)²

⇒ A = 196π ft²

Answer:

y=2x-4

Step-by-step explanation: this looks alot like an equation for slope is it?

Answer:

-2x - y = 4

Step-by-step explanation:

Standard Form: Ax + By = k

Note that while k is a variable, it stands for constant, which means the number with no variables attached would fill in the space. Isolate the constant. Subtract y, and add 3 to both sides:

y + 1 = -2x - 3

y (-y) + 1 = -2x - 3 (-y)

1 = -2x - 3 - y

1 = -2x - 3 - y

1 (+3) = -2x - 3 (+3) - y

4 = -2x - y

Set the equation so that it looks like the standard form equation given above:

-2x - y = 4 is your answer.

Answer:

x = 5

Step-by-step explanation:

The information given has been sketched out in the attachment below.

Line segment EJ is an angle bisector of angle DEF. Therefore, m<DEJ = m<JEF.

The equation to find x would be expressed as follows:

5x + 7 = 8x - 8

Subtract 5x from each side (subtraction property of equality)

5x + 7 - 5x = 8x - 8 - 5x

5x - 5x + 7 = 8x - 5x - 8

0 + 7 = 3x - 8

7 = 3x - 8

Add 8 to both sides of the equation (addition property of equality)

7 + 8 = 3x - 8 + 8

15 = 3x

Divide both sides by 3

15/3 = 3x/3

5 = x

x = 5
