Answer:

Discount % = (Discount/List Price) × 100

Step-by-step explanation:

To calculate the discount, you must have the list price (marked price) and the selling price of the product you are buying.

Example: If the list price of a book is $50, and $10 discount is offered on the book, then the discount percentage is calculated as follows.

Discount % = (Discount/List Price) × 100

List price = $50; discount = $10

Discount (%) = (10/50) × 100

= 100/5

= 20%

Answer: f(3)= 7, f(0)= -5, f(-2)= -13

Step-by-step explanation:

Substitute and plug in.

For f(3), we plug in 3 for x in the equation.

So, 4(3)-5, which is just 12-5, which is 7

We do the same for f(0),

4(0)-5, which is 0-5, which is -5

Once again for f(-2),

4(-2)-5, which is -8-5, which is -13

Answer:

16k with the little 2 by the k so like 16k2-4(2)(-5k)

Step-by-step explanation:

ANSWER IS -5/2<K<0.

The set of possible values for k is -4<k<-5/2.

The given equation 20x²=4kx-13kx²+2 and the inequality is 2k²+13k+20<0.

For a given quadratic equation ax² + bx + c = 0, the values of x that satisfy the equation are known as its roots. i.e., they are the values of the variable (x) which satisfies the equation. The roots of a quadratic function are the x-coordinates of the x-intercepts of the function.

The given equation has no real roots.

4kx-13kx²+2-20x²=0

⇒ 4kx-x²(13k+20)+2 = 0

If the discriminant of a quadratic function is less than zero, that function has no real roots.

Compare 4kx-x²(13k+20)+2=0 with ax² + bx + c = 0, we get a= - (13k+20), b=4k and c = 2.

So, b²-4ac<0

(4k)²-4(-(13k+20))(2)<0

⇒ 16k²+8(13k+20)<0

⇒ 8(2k²+13k+20)<0

⇒ 2k²+13k+20<0

Using splitting middle term method, we get

2k²+8k+5k+20<0

⇒ 2k(k+4)+5(k+4)<0

⇒ (k+4)(2k+5)<0

⇒ -4<k<-5/2

Therefore, the set of possible values for k is -4<k<-5/2.

Answer:

0.8x − 11 = 0.3x + 41

0.8x-0.3x=41+11

0.5x=52

x=52/0.5

x=104

Answer:

x = 104

Step-by-step explanation:

0.8x - 11 = 0.3x + 41

0.8x - 0.3x = 41 + 11 (collecting the variables on one side)

0.5x = 52

x = 52 / 0.5

x = 104

Answer:

a) To find the other missing length we must be given an area and a length

We then divide the total area by the given length

so

6534/99 = 66 is the missing width

Step-by-step explanation:

5) angle 5 = 69°

than, angle 10 = 69° ( alternate interior angle )

6) angle 6 = 115° ( alternate interior angle )

7) angle 7 = 118° ( alternate interior angle )

8) angle 11 = angle 4 - 180

→ 72 - 180 = 108°

therefore, angle 11 = 108°

9) angle 14 = 114° - 180

→ angle 14 = 66°

10) angle 12 = 86° ( alternate interior angle)

Answer: 39 hot dogs

M= 3 + half of C , E= 2 × M , C= 12

Step-by-step explanation:

M= 3 + (half of C=12÷2) 6= 9

E=2×9=18

total= 12 + 9 + 18= 39

Laura put $18 toward the present. Therefore, the correct answer is F. $18. Let's use variables to represent the amounts that Lilly and Laura contributed.

Let L be the amount Lilly contributed and 2/3L be the amount Laura contributed.

According to the information given:

L + 2/3L = $45

To solve for L, combine the terms with L:

1L + 2/3L = $45

To combine the fractions, find a common denominator:

(3/3)L + 2/3L = $45

Now, the fractions have a common denominator:

(5/3)L = $45

To isolate L, divide both sides by 5/3:

L = $45 / (5/3)

To divide by a fraction, multiply by its reciprocal:

L = $45 * (3/5)

L = $9 * 3

L = $27

So, Lilly contributed $27.

Now, to find how much Laura contributed:

Laura's contribution = 2/3L = 2/3 * $27 = $18
