jaunice is redecorating her room. to cover a rectangular section of her wall, she needs at least 76.5 square feet of paint. the height of the wall is 8.5 feet. what is the minimum length of the wall?

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

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

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:

Statement. Reason

→ 9(x-6)+41 = 75. Transposing the like terms.

→ 9(x-6) = 75 - 41 Performing subtraction of the term in RHS

→ 9(x-6) = 34 Performing multiplication in LHS.

→ 9x - 54 = 34 Distributive property

→ 9x = 34 + 54 Performing addition of the term in RHS.

→ 9x = 88. Now, transpose 9 from LHS to RHS , it's arthmetic operator will get changed.

→ x = 88/9

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%

2A^2 +3B-4C

2(-4)^2+3(20)-4(0)

In short, 92 is the answer.

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)

hope this answer helps you dear...take care!

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: 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
