Answer:

You have to buy more than 20 books to make Cool Cover Bookstore club a better deal.

Step-by-step explanation:

Given that:

Fee charged by Fun Reads Bookstore = $40

Charges per book = $5

Let x be the number of books.

A(x) = 5x+40

Fee charged by Cool Covers Bookstore = $100

Charges per book = $2

B(x) = 2x+100

For making Cool Cover Bookstores club a better deal,

B(x) > A(x)

2x+100 > 5x+40

2x-5x > 40-100

-3x > -60

Dividing both sides by -3

[tex]\frac{-3x}{-3}>\frac{-60}{-3}\\x>20[/tex]

Hence,

You have to buy more than 20 books to make Cool Cover Bookstore club a better deal.

Answer:

2

Step-by-step explanation:

the area of the radius 30 is 2827 and since 1 bucket can cover 1800 we will only need 2 buckets because we need a total of 2827 and 1 bucket covers 1800 so 2 buckets will cover 3600.

The smallest number of 5-gallon cans the painter must buy to cover the bottom of the pool is 2 and this can be determined by using the unitary method.

Given :

First, find the value of the area of the bottom of the pool. And it can be determined by using the below formula:

[tex]\rm Area = \pi r^2[/tex]

Area = 2827.43 square feet

Now, if one gallon of paint covers 300 square feet then 2837.43 square feet area covers by:

[tex]=\dfrac{2827.44}{300}\times 1[/tex]

= 9.43 gallons of paint

So, to cover the whole bottom area of the pool with paint then the amount of paint required is 9.43 gallons.

Now, if one can contain 5 gallons of paint then 9.43 gallons of paint is contained by :

[tex]=\dfrac{9.43}{5}[/tex]

= 1.886 [tex]\approx[/tex] 2

The smallest number of 5-gallon cans the painter must buy to cover the bottom of the pool is 2.

Answer:

x^2+13x+40 remainder 7. (or 7/(1-5))

Step-by-step explanation:

Answer:

x² + 13x + 40 + [tex]\frac{7}{x-5}[/tex]

Step-by-step explanation:

Using Synthetic division

dividing by ( x - 5) , thus use h = 5

5 |   1    8    - 25    - 193

       ↓    5      65      200

             +       +        +

    ---------------------------------

      1     13      40       7 ← remainder  

quotient = x² + 13x + 40

Thus

[tex]\frac{x^3+8x^2-25x-193}{x-5}[/tex] = x² + 13x + 40 + [tex]\frac{7}{x-5}[/tex]

Answer:

Step-by-step explanation:

i think the last number 2.50 is wrong, maybe is 2.4

total cost= 0.30 x number of miles

for the first 0.30*2=0.60

second 0.30*4=1.20

and so on

Answer:

.60 ÷ 2 = 0.3

1.20 ÷ 4 = 0.3

1.80 ÷ 6 = 0.3

2.50 ÷ 8 = 0.3125 so round it, and it equals 0.3

So are equation would be y ÷ x = 0.3

Answer:

1,302 triangles

Step-by-step explanation:

All triangles are formed by the intersection of three diagonals at three different points. There are five arrangements of three diagonals to consider. We classify them based on the number of distinct diagonal endpoints. We will directly count the number of triangles with 3, 4, and 5 endpoints. We will then count the number of potential triangles with 6 endpoints, then correct for the false triangles.

You can make 84 triangles with 3 diagonal endpoints, 504 triangles with 4 diagonal endpoints, 630 triangles with 5 diagonal endpoints, and 84 triangles with 6 diagonal endpoints. This adds up to be 1,302 triangles altogether.

The values of [tex]w[/tex] that make the inequality [tex]-w\ge7[/tex] true are

[tex]\{... ,-11,-10,-9,-8,-7\}[/tex]. An equivalent inequality, in terms of [tex]w[/tex], is [tex]w\le-7[/tex]

To get the values that make the inequality true, we have to solve the inequality for [tex]w[/tex]. This will also give an equivalent inequality in terms of [tex]w[/tex]

[tex]-w\ge7\\\\\implies \dfrac{-w}{-1}\le\dfrac{7}{-1}\\\\w\le-7[/tex]

the solution set is the set of values [tex]\{... ,-11,-10,-9,-8,-7\}[/tex]. In other words, [tex]w[/tex] can take up values less or equal to [tex]-7[/tex] to make the inequality  [tex]-w\ge7[/tex] true

Also, the inequality equivalent to [tex]-w\ge7[/tex] is [tex]w\le-7[/tex]

Answer:

15. [tex] x = 8 [/tex]

16. m<V = 103°

17. [tex] x = 14 [/tex]

Step-by-step explanation:

15. The figure given is quadrilateral. Sum of interior angles of a quadrilateral = 360°

Therefore:

[tex] (10x + 6) + (13x - 2) + (8x - 1) + (180 - 71) = 360 [/tex]

Solve for x

[tex] 10x + 6 + 13x - 2 + 8x - 1 + 109 = 360 [/tex]

Add like terms

[tex] 31x + 112 = 360 [/tex]

Subtract 112 from each side

[tex] 31x = 248 [/tex]

Divide both sides by 31

[tex] x = 8 [/tex]

16. The polygon is a hexagon. Sum of interior angles of a hexagon = 720. Therefore:

[tex] 90 + (7x + 3) + 128 + (5x + 8) + 111 + (9x - 19) = 720 [/tex]

Solve for x

[tex] 90 + 7x + 3 + 128 + 5x + 8 + 111 + 9x - 19 = 720 [/tex]

Add like terms

[tex] 321 + 21x = 720 [/tex]

Subtract 321 from each side

[tex] 21x = 399 [/tex]

Divide both sides by 21

[tex] x = 19 [/tex]

m<V = 5x + 8

Plug in the value of x

m<V = 5(19) + 8 = 95 + 8

m<V = 103

17. The polygon is a regular pentagon. This means each of the angles measures 108°. The sum of the interior angles all together is 540.

Therefore:

[tex] (9x - 18) = 108 [/tex]

Solve for x

[tex] 9x - 18 = 108 [/tex]

Add 18 to both sides

[tex] 9x = 126 [/tex]

Divide both sides by 9

[tex] x = 14 [/tex]

Answer:

32768 ways

Step-by-step explanation:

Given

Marbles = 8 marbles

Selection = 5 (with replacement)

Required

Determine the number of ways

Because it is a selection with replacement; each selection is as follows:

[tex]First = 8\ marbles[/tex]

[tex]Second = 8\ marbles[/tex]

[tex]Third= 8\ marbles[/tex]

[tex]Fourth = 8\ marbles[/tex]

[tex]Fifth = 8\ marbles[/tex]

Total number of ways is then calculated as:

[tex]Total = 8 * 8 * 8 * 8 * 8[/tex]

[tex]Total = 32768[/tex]
