The final answer would be 3.5 inches tall or if you need fractions it would be 3 and 1/2. Here’s the explanation: the candle is originally eight inches tall and for every hour it burns it loses 3/4 of an inch which is .75. It will be burning till 11:00 at night which means it will be burning for six hours. All you need to do is multiply how much of the candle is burned every hour (.75) by how many hours. This will give you 4.5 inches burned by 11:00. But the question asked for how tall the candle will be, so you simply just subtract how much of the candle will have burned(4.5 inches) by the height (8 inches) and you get 3.5 inches.

4.5 inches

Step-by-step explanation:

Step 1: Define Equation

10(1/2x + 2) - 5 = 3(x - 6) + 1

Step 2: Solve for x

Distribute: 5x + 20 - 5 = 3x - 18 + 1
Combine like terms: 5x + 15 = 3x - 17
Subtract 3x on both sides: 2x + 15 = -17
Subtract 15 on both sides: 2x = -32
Divide 2 on both sides: x = -16

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x: 10(1/2(-16) + 2) - 5 = 3(-16 - 6) + 1
Multiply: 10(-8 + 2) - 5 = 3(-16 - 6) + 1
Add/Subtract: 10(-6) - 5 = 3(-22) + 1
Multiply: -60 - 5 = -66 + 1
Subtract/Add: -65 = -65

Here we see that -65 does indeed equal -65.

∴ x = -16 is the solution of the equation.

Answer:

$n^(8)$

Step-by-step explanation:

Given the Quotient Rule of Exponents: $(a^(m))/(a^(n)) = a^((m-n))$ , you must subtract the exponents of each exponential expression (in fractions) before applying the Product Rule of Exponents (I will explain in a while what it means).

First, subtract the exponents of the first fraction, $(n^(5))/(n^(3)) = n^((5 - 3)) = n^(2)$

Next, subtract the exponents of the second fraction: $(n^(9))/(n^(3)) = n^((9 - 3)) = n^(6)$

At this point, we have the following exponential expressions: $n^(2)$ and $n^(6)$ .

Since the required operation is multiplication, then you can apply the Product Rule of Exponents: $a^(m) a^(n) = a^((m+n))$

$n^(2)*n^(6) = n^((2+6)) = n^(8)$

Therefore, the correct answer is $n^(8)$ .

A rectangle is shown. The length of the rectangle is labeled as 8 cm, and the width is labeled as 6 cm. What will be the perimeter and the area of the rectangle below if it is enlarged using a scale factor of 4.5? (5 points)Perimeter = 46 cm, area = 131.25 cm2
Perimeter = 126 cm, area = 972 cm2
Perimeter = 46 cm, area = 972 cm2
Perimeter = 126 cm, area = 131.25 cm2
Perimeter = 46 cm, area = 131.25 cm2
Perimeter = 126 cm, area = 972 cm2
Perimeter = 46 cm, area = 972 cm2
Perimeter = 126 cm, area = 131.25 cm2

Answers

Answer:

Perimeter = 126 cm, area = 972 cm2

Step-by-step explanation:

Rectangle perimeter:

P = 2(w + l)

Rectangle area:

A = wl

When scaled, the perimeter will change by same factor but the area by the square of same factor.

Applying to the given rectangle

Perimeter:

P = 2(6 + 8)(4.5) = 126 cm

Area:

A = 6*8*4.5² = 972 cm²

Correct choice is B

Answer:

Perimeter = 126cm

Area = 972cm^2

Step-by-step explanation:

6*4.5 = 27

8*4.5 = 36

Perimeter = 27*2+36*2= 126 cm

Area = 27*36 = 972 cm^2

Hope this helped!
