What is the measure of L?

Answer:

4 books

Step-by-step explanation:

The cost for one used = $2.27

The question requires you to find the number of books that could be purchased with $10

Let assume the cost for a single used book to be $ t

If you have $ x in your pocket then the number of books you can purchase with $ x will be;

number of books= $ x/ $t.............................(a)

Applying this expression to the question;

$t= $2.27

$ x= $10

number of books = $10/$2.27 = 4.405 = 4 books

The point slope form of this line is y+5=m(x).  Now, you need to find m (the slope) of the line using the formula (y1-y2)/(x1-x2):

(-5-4)/(0--3)

-9/3

-3

The complete point slope formula is: y+5=-3x.

Now, to fin the slope intercept form, just solve for y:

y+5=-3x

*Subtract 5 from both sides*

y=-3x-5

Hope this helps!!

Answer:

y = -3x - 5.

Step-by-step explanation:

y – y1 = m(x – x1)

The slope m =  rise /run = (4 - -5) / (-3 - 0)

= 9/-3

= -3.

Using the point (0, -5) and m =-3 in the point-slope:

y - -5 = -3(x - 0)

y + 5 = -3x

y = -3x - 5 is the required  slope-intercept form.

Answer: 23 = x

Step-by-step explanation: The first, and in this case, only step, is the simplify the equation. We do not have to get the variable on one side since it already is. 27-4 = 23, so our answer will be 23.

Answer:

843.67

Step-by-step explanation:

896 is the original price

A 12% discount will be applied so what is 12% of 896 =.12(896)=107.52

So we started with 896 and we are taking off 107.52=896-107.52=788.48

So the price after the discount is 788.48.

Now to apply the tax which is 7%=.07  so we need to find 7% of 788.48=.07(788.48)=55.19 (This is the tax dollar amount to be added to the price before tax).

So Sara is paying 788.48+55.19=843.67

Answer:

843.67

Step-by-step explanation:

Take the original price and find the discount

896 * 12 %

896 * .12

107.52

The new price is the original price minus the discount

896-107.52

788.48

Now we need to find the tax on the sale price

788.48 * 7%

788.48 *(.07)

55.19

Add the sale price and the tax to find the total price

788.48 +55.19

843.67

Answer:

-21.79.

Step-by-step explanation:

(-10.5 + m) / 11.57 = -2.748

(-10.5 + m) = -2.748 (11.57)

-10.5 + m = -31.794

m = -31.794 + 10.5 = -21.79.

Answer:

-21.29

Step-by-step explanation:

-10.5+m/11.57=-2.748

-10.5+m=-2.748*11.57

-10.5+m=-31.79436

m=-31.79436+10.5

m=-21.29

Answer:

Step-by-step explanation:

6x+4y=32

-6x+4y=8

We will add the two equations together to eliminate x

6x+4y=32

-6x+4y=8

----------------------

      8y = 40

Divide each side by 8

8y/8 = 40/8

y = 5

Multiply the first equation by -1

-6x-4y = -32

-6x+4y=8

------------------

-12x = -24

Divide by -12

-12x/-12 = -24/-12

x = 2

Answer:the answer is y is less than or equal to 17

Step-by-step explanation: if y + 8 is less than or equal to 25, all you have to do is subtract 8 to 25 and the answer has to be less than or equal to the number

Answer:

Final answer:

The odds against selling a car today, when the probability of selling a car is 0.28, are calculated by dividing the complement of this probability (0.72) by the original probability (0.28), resulting in odds of approximately 2.6 to 1.

Explanation:

To find the odds against selling a car today, we start with the given probability of selling a car, which is 0.28, or 28%. The probability of not selling a car, which is the complement of the given probability, is therefore 1 - 0.28 = 0.72, or 72%.

Odds can be expressed as a ratio of the probability of the event occurring to the probability of the event not occurring. In this case, the odds against selling a car are the ratio of the probability of not selling the car to the probability of selling the car:

Odds against = Probability of not selling / Probability of selling = 0.72 / 0.28 = 72/28. This ratio can be simplified by dividing both the numerator and the denominator by 28 to get the simplest form.

Thus, the simplified odds against selling a car are 2.57 : 1 (or approximately 2.6 to 1).

Answer:

Step-by-step explanation:

You have that [tex]i^2=-1[/tex], so we must have

[tex]i^4=(i^2 )(i^2)=(-1)(-1)=1[/tex].

This says that we must make groups of four [tex]i[/tex]'s for simplify because they becomes 1, and the last group that is not of four [tex]i[/tex]'s is the result.

This is equivalent to divide 256 by 4 and use the remainder of that division, that is 0, as the new power of [tex]i[/tex], and the result is 1 because [tex]i^0 =1.[/tex]. You can see the operation:

[tex]i^{256} = (i^4)^{64}\times i^0 =1[/tex]

Answer:

Step-by-step explanation:

X²=12x-40

X²-12x+40=0

a=1  and b= -12 and c = 40

delta = b² - 4ac

delta = (-12)² - 4(1)(40) = 144 - 160 = - 16 = (4i)² ....i² = -1

x1= (12-4i)/2 =6-2i

x1= (12+4i)/2 =6+2i

Answer:

Step-by-step explanation:

x^2 = 12 x-40

x² - 12x + 40 = 0

a = 1;  b = -12; c = 40

4ac - b² = 4*1*40 - (-12)² = 160 - 144 = 16

x = -b ± √4ac-b² i / 2a

 = -(-12) ± √ 16 i

          2 * 1

= (12 ± 4 i )/ 2

= 2( 6 ±  2i)

        2

=   6 ±  2i

Answer: the answer is 40 because 20 plus 20 equals 40

20 + 20 = 40

If you add 2 + 2 = 4 (the number values in the tens place) and 0 + 0 = 0 (the number values in the ones place). Put the 4 in tens place and 0 in the ones place which is 40

7.5c-2.5c+8=-7

Combine the like terms:

7.5c-2.5c = 5c

Now you have 5c +8 = -7

Subtract 8 from both sides:

5c = -15

Divide both sides by 5:

c = -15/5

c = -3

Answer:

C = -3

Step-by-step explanation:

To solve this, we need to isolate the c. So we need to subtract 8 on both sides to get :

7.5c-2.5c = -15

Now combining the c's we get:

5c = -15

So c = -3

Answer:

819.54 cm^2

Step-by-step explanation:

We are given

Slant height = l = 20cm

and

Diameter = d = 18 cm

We have to find radius first

r = d/2 = 18/2 = 9 cm

The formula for surface area is:

[tex]SA = \pi rl+\pi r^2\\= (3.14 * 9 * 20) + (3.14 * (9)^2)\\=565.5+254.34\\=819.84\ cm^2[/tex]

As second option is nearest to calculated answer, it is the correct option ..

Answer: second option.

Step-by-step explanation:

We know that we can calculate the surface area of a cone with this formula:

[tex]SA=\pi rl + \pi r^2[/tex]

Where "r" is the radius and "l" is the slant heigth.

We know that the radius is half the diameter, then the radius of this cone is:

[tex]r=\frac{18cm}{2}\\\\r=9cm[/tex]

Since we know the radius and the slant height, we can substitute values into the formula, using 3.14 for π.

Therefore, we get:

 [tex]SA=(3.14)(9cm)(20cm) + (3.14)(9cm)^2=819.54cm^2[/tex]

ANSWER

[tex]p = - 3[/tex]

The completely factored form is

[tex](x + 1)(x - 1)( 3x - 1)[/tex]

EXPLANATION

The given polynomial expression is

[tex]3 {x}^{3} - {x}^{2} + px + 1[/tex]

Let

[tex]f(x) = 3 {x}^{3} - {x}^{2} + px + 1[/tex]

According to the Remainder Theorem, if f(x) is exactly divisible by x-1, then the remainder is zero.

This implies that:

[tex]f(1) = 0[/tex]

[tex]3 {(1)}^{3} - {(1)}^{2} + p(1)+ 1 = 0[/tex]

[tex]3 - 1 + p + 1 = 0[/tex]

[tex]3 + p = 0[/tex]

[tex]p = - 3[/tex]

When we substitute the value of p back into the function, f(x) we get:

[tex]f(x) = 3 {x}^{3} - {x}^{2} - 3x + 1[/tex]

We now perform long division as shown in the attachment.

We can factor the function to get:

[tex]f(x) =(x - 1)( 3 {x}^{2} + 2x - 1)[/tex]

We now split the middle term of the quadratic term and factor it completely to obtain:

[tex]f(x) =(x - 1)( 3 {x}^{2} + 3x - x - 1)[/tex]

[tex]f(x) =(x - 1)( 3x(x + 1) - 1(x + 1))[/tex]

[tex]f(x) =(x - 1)( 3x - 1)(x + 1) [/tex]

[tex]f(x) =(x + 1)(x - 1)( 3x - 1)[/tex]

Answer:

(-7, 6).

Step-by-step explanation:

All sides are equal since it is a square.

The length of the side joining the first 2 points is  |-7 - 6| = 13 units and it is horizontal.

The adjacent side is vertical and also has length 13  and moves up from the last line.

So the missing coordinate has a y coordinate of  6 and an x coordinate of -7.

Answer:

7/11 of the Pizza was left for Zachary.

Step-by-step explanation:

Zachary had 1 - 4/11

= 11/11 - 4 /11

= 7/11.

Final answer:

Jerome ate 4/11 of the pizza, which means that Zachary has 7/11 of the pizza left to eat after subtracting Jerome's portion from the whole pizza.

Explanation:

If Jerome ate 4/11 of the pizza, we need to determine how much is left. Since the whole pizza represents 1, or 11/11, we subtract what Jerome ate from the whole to find out what remains for Zachary. Therefore, we perform the following subtraction:

1/11 (whole pizza) - 4/11 (portion eaten by Jerome) = 7/11 (portion left for Zachary)

So, Zachary has 7/11 of the pizza left to eat.

Final answer:

The equivalent expression for  [tex](4^5/4 \times 4^1/4 \div 4^1/2)^1/2[/tex] is 2, found by applying properties of exponents such as multiplication, division, and power of a power.

Explanation:

The expression given is  [tex](4^5/4 \times 4^1/4) \div 4^1/2)^1/2.[/tex] To find the equivalent expression, we use the properties of exponents, which include multiplication, division, and taking a power of a power. When you multiply with the same base, you add the exponents, and when you divide, you subtract the exponents. Also, taking a power of a power means you multiply the exponents.

Following these rules:

Combine the exponents for the terms that multiply: 5/4 + 1/4 = 3/2, hence the expression simplifies to [tex]4^{(3/2)}.[/tex]

Subtract the exponent of the denominator: (3/2) - (1/2) = 1, so now we have [tex]4^1.[/tex]

Finally, apply the outer exponent of  [tex]1/2: (4^1)^{(1/2)}[/tex]which means we take the square root of 4, giving us 2 as the final answer.
