I learned this trick that can help us with this question easily!

14% of 500 - 70 - Drama
14 * 5 = 70.

22% of 500 - 110 - Sports
22 * 5 = 110

20% of 500 - 100 - Reality
20 * 5 = 100

20% of 500 - 100 - Sci-fi
20 * 5 = 100

70 + 110 + 100 + 100 = 380

500 - 380 = 120

Therefore, documentaries is labeled as 24% of 500 or 120 out of 500.

Answer:

40

Step-by-step explanation:

Assign the variable x to Devaughn's age. If Devaughn is 7 years older than Sydney, then Sydney must be 7 years younger than him, so the expression x - 7 can represent Sydney's age.

The sum of their ages would be x + x - 7 or 2x - 7 which is also said to equal  87. Therefore, this can be written as an equation and be solved accordingly:

2x - 7 = 87

2x = 94

x = 47

Therefore, Devaughn is 47 and Sydney, who is 7 years younger, is 40.

Sydney's age is determined by setting up and solving a simple algebraic equation based on the information provided. The equation that represents this situation is S + (S + 7) = 87, which leads to the conclusion that Sydney is 40 years old.

Devaughn is 7 years older than Sydney. Given that the sum of their ages is 87, we can represent this situation with algebra. Let's denote Sydney's age as S.

Considering Devaughn is 7 years older, we can represent his age as S + 7. Given that the sum of their ages is 87, we can write down this equation: S + (S + 7) = 87.

Solving this equation will help us find Sydney's age. First, simplify the left side: 2S + 7 = 87. Then, subtract 7 from both sides: 2S = 80. Finally, divide both sides by 2 to solve for S, yielding Sydney's age: S = 40.

It will take 5 minutes to paint this cone

Since the area of the base of the cone is doubled, the new base area becomes 2 * 49π in² = 98π in².

The radius of the original cone can be found by using the formula for the area of a circle:

49π = πr^2

r = 7 in

The height of the new cone can be calculated using the same lateral height as the original cone:

h = 8 in

Using the formula for the volume of a cone, we can calculate the volume of the new cone:

V = (1/3)πr^2h = (1/3)π(7^2)(8) = (1/3)π(392)

The surface area of the original cone can be found using the formula for the surface area of a cone:

A = πr^2 + πrs

where s is the slant height of the cone.

s = √(r^2 + h^2) = √(7^2 + 8^2) = √(49 + 64) = √(113)

So, we have

A = πr^2 + πrs = π(7^2) + π(7)(√(113)) = 49π + 7π(√(113))

The surface area of the new cone can be found using the same formula:

A = πr^2 + πrs = π(7^2 * 2^2) + π(7 * 2)(√(113)) = 98π + 14π(√(113))

When the equations are compared, we have

2 * 49π + 7π(√(113)) = 98π + 14π(√(113))

Since the new cone has twice the surface area of the original cone and can be painted at the same rate,

It will take 2.5 * 2 = 5 minutes to paint this cone.

Step-by-step explanation:

Answer:

  3.5%

Step-by-step explanation:

You want the percent error in a measured value of 4.16 g/cm³ in relation to a handbook value of 4.018 g/cm³.

The percentage error is calculated as ...

  % error = ((measured) - (actual))/actual × 100%

  = (4.16 -4.018)/4.018 × 100%

  = 0.142/4.018 × 100% ≈ 3.5%

The given numbers, 4.16 and 4.018 have 3 and 4 significant figures, respectively. Their difference will have 2 significant decimal places, as does 4.16, so should be considered to be 0.14. This value has 2 significant figures, so the final answer will have 2 significant figures.

You will note that we kept all of the digits available throughout the computation, rounding to 2 significant figures only at the end.

You will also note that taking differences of numbers of approximately the same value can result in a loss of significant figures.

diffrence of 164 and 11 = 164 - 11 = 153

Answer:

[tex]22212[/tex].

Step-by-step explanation:

In base-10, for a number to be divisible by [tex]4[/tex], the last two digits must also be divisible. Among all the two-digit numbers formed with "[tex]\texttt{1}[/tex]" and "[tex]\texttt{2}[/tex]", only [tex]12[/tex] satisfies the requirements as the last two digits of [tex]N[/tex].

For a number to be divisible by [tex]9[/tex], the sum of all the digits must also be divisible. For [tex]N\!\![/tex] to be as small as possible, its digits should add up to the smallest multiple, [tex]1 \times 9 = 9[/tex], instead of larger ones such as [tex]18[/tex].

Since the last two digits of [tex]N[/tex] is [tex]\texttt{1}[/tex] and [tex]\texttt{2}[/tex], the other digits of [tex]N\![/tex] would need to add up to [tex]9 - 1 - 2 = 6[/tex]. To minimize the value of [tex]N\!\![/tex], these digits should consist solely of [tex]\texttt{2}[/tex]: [tex]2 + 2 + 2 = 6[/tex]. Therefore, the answer should be [tex]22212[/tex].

The values of the ratios of the perimeters and areas of the red figure to the blue figure, which are similar figures, in the simplest form are:

The ratio of their perimeters:  28/16

The ratio of their areas:  (28)²/(16)²

What is the ratio?

A ratio is a relationship between two things when it is expressed in numbers or amounts.

The ratio of the perimeter of similar figures = a side length of one figure / corresponding side length of the other figure

The ratio of the areas of two similar figures = square of the length of one figure/square of the corresponding length of the other

Thus:

The side length of Red-figure = 28

The side length of the Blue figure = 16

Therefore:

The ratio of their perimeter = Side length of the red figure / Side length of the blue figure

The ratio of the perimeter of the red figure to the blue figure = 28/16

The ratio of their areas = Side length of the red figure / Side length of the blue figure

The ratio of the areas of the red figure to the blue figure = (28)²/(16)²

Hence, The values of the ratios of the perimeters and areas of the red figure to the blue figure, which are similar figures, in the simplest form are:

The ratio of their perimeters:  28/16

The ratio of their areas:  (28)²/(16)²

The dimensions of the original piece of rectangular cardboard are 22 in by 40 in

A prism is a polyhedron comprising an n-sided polygon base, a second base which is a translated copy of the first, and n other faces, necessarily all parallelograms, joining corresponding sides of the two bases.

Given that, Lorene plans to make several open-topped boxes in which to carry plants. She makes the boxes from rectangular sheets of cardboard, from which she cuts out 9-in squares from each corner. The length of the original piece of cardboard is 18 in more than the width, the volume of the box is 792 in³,

We know that volume of rectangular box = length × width × height

length = x+18-9-9 = x

height = 9

width = x-9-9 = x+18

= (x-18) × x × 9

(x-18)×9x = 792

9x²-162x-792 = 0

x²-18x-88 = 0

Factorizing to find the value of x,

x = 22 and x = -4

Therefore, width of the cardboard = 22 in

Length = 22+18 = 40 in

Hence, the dimensions of the original piece of rectangular cardboard are 22 in by 40 in

The given expression is a logarithm expression. The value of the log expression is -112.

What is an expression?

Mathematical expressions consist of at least two numbers or variables, at least one math operation, and a sentence. It's possible to multiply, divide, add, or subtract with this mathematical operation.

The given expression is log (³√c⁵)/(a⁷b⁸).

The value of log a = 7, log b = 11, log c = 15

Applying the quotient formula log(a/b) = log a - log b in the given expression:

= log (³√c⁵) - log (a⁷b⁸)

Again applying the product formula log (ab) = log a + log b:

= log (³√c⁵) - log (a⁷) - log b⁸

Apply the power rule log (a^b) = b log a:

= (5/3) log c - 7log a - 8log b

Now putting the value of log a = 7, log b = 11, log c = 15:

= (5/3) × 15 - 7 × 7 - 8 × 11
