Answer:

= 2808.6%

"Percent" means "per 100" or "over 100". So, to convert 28.086 to percent we rewrite 28.086 in terms of "per 100" or over 100.

Multiply 28.086 by 100/100. Since 100/100 = 1, we are only multiplying by 1 and not changing the value of our number.

28.086/1×100/100=2808.6100

2808.6/100 is 2808.6 over 100 and means 2808.6 per 100. 2808.6 "per 100" means 2808.6 "percent" or 2808.6%

Therefore, we have shown that

28.086 = 2808.6%

Multiply by 100 and add the percent sign %

28.086 × 100 becomes 2808.6%

Move the decimal point 2 places to the right and add the percent sign %

28.086 becomes 2808.6%

Answer:

Percent Change Formula: [(new - old)/old] * 100

Step-by-step explanation:

New - old

80 - 20 = 60

Difference between new - old divided by old

60/20 = 3

Previous quotient times 100

3*100 = 300

Percent Change is 300%

Check your answer

300% of 20 is 60

20 + 60 = 80

Answer:

300%

Step-by-step explanation:

percent change = (new value - old value)/(old value) * 100%

percent change = (80 - 20)/20 * 100%

percent change = 60/20 * 100%

percent change = 3 * 100%

percent change = 300%

Gianna is 90 miles far away in 3 hours of driving.

She drove in total of 180 minutes.

The speed can be defined as the rate at which an object covers some distance. Speed can be measured as the distance traveled by a body in a given period of time. The SI unit of speed is m/s.

Given,

Gianna drives 5 miles in 10 minutes

Speed per minute = 5/10 = 0.5 miles/minute

Gianna drove in total for 3 hours

1 hour = 60 minutes

3 hours = 60 × 3 = 180 minutes

Distance Gianna drove in 180 minutes = speed per minute × time

                                                                = 0.5 × 180

                                                                = 90 miles

Hence, Gianna drove 90 miles in 3 hours, 180 minutes is total time she drove.

The polynomials completely factorized have the following expressions;

50). x³ - 3x² - 26x - 12 = (x - 6)(x + 1)(x + 2)

51). x³ - 12x² + 12x + 80 = (x - 10)(x + 2)(x - 4)

52). x³ - 18x² + 95x + 126 = (x - 9)(x - 2)(x - 7)

53). x³ - x² + 21x + 45 = (x + 5)(x - 3)(x - 3)

For the polynomial x³ - 3x² - 26x - 12 divisible by x - 6;

(x³ - 3x² - 26x - 12)/(x - 6) = x² + 3x + 2

x² + 3x + 2 = (x + 1)(x + 2)

so;

x³ - 3x² - 26x - 12 = (x - 6)(x + 1)(x + 2)

For the polynomial x³ - 12x² + 12x + 80 divisible by x - 10;

(x³ - 12x² + 12x + 80)/(x - 10) = x² - 2x - 8

x² - 2x - 8 = (x + 2)(x - 4)

so;

x³ - 12x² + 12x + 80 = (x - 10)(x + 2)(x - 4)

For the polynomial x³ - 18x² + 95x + 126 divisible by x - 9;

(x³ - 12x² + 12x + 80)/(x - 9) = x² - 9x + 14

x² - 9x + 14 = (x - 2)(x - 7)

so;

x³ - 18x² + 95x + 126 = (x - 9)(x - 2)(x - 7)

For the polynomial x³ - x² + 21x + 45 divisible by x + 5;

(x³ - x² + 21x + 45)/(x + 5) = x² - 6x + 9

x² - 6x + 9 = (x - 3)(x - 3)

so;

x³ - x² + 21x + 45 = (x + 5)(x - 3)(x - 3)

Therefore, by complete factorization the expressions (x - 6)(x + 1)(x + 2), (x - 10)(x + 2)(x - 4), (x - 9)(x - 2)(x - 7), and (x + 5)(x - 3)(x - 3) are the factors of their respective polynomial.

The answers both as whole numbers and fractions are given below:

In mathematics, the limit of a function is the value that the function approaches as its input (independent variable) gets arbitrarily close to a certain value, often denoted as a.

More precisely, given a function f(x), the limit of f(x) as x approaches a, written as "lim x → a f(x)", is the value that f(x) approaches as x gets arbitrarily close to a, but not necessarily equal to a.

If the limit exists and is equal to L, then we can write it as:

lim x → a f(x) = L

To solve this,

using the graph of y = f(x)

\(\lim_{x \to 4^+\} \frac{f(x) - 4}{f(x+3)}\) = 3-4/6 = -1/6

\(\lim_{x \to 1^-\}{f(fx) +4) = f(4 +4) = f(8)\) = 5

\(\lim_{h \to 0\} \frac{f(2+h) - f(2)}{h}\) = f^1(2) = 1

Answer:

x = -2y + z

y = -1/2x + 1/2z

z = x + 2y

Step-by-step explanation:

x:

First, isolate the variable you want to solve for:

To isolate x, add the inverses of y and z to both sides of the equation.

2x + 4y - 2z = 0

2x - 2z = -4y

2x = -4y + 2z

To find x, divide both sides by 2:

2x = -4y + 2z

x = -2y + z

y:

First, isolate the variable you want to solve for:

To isolate y, add the inverses of x and z to both sides of the equation.

2x + 4y - 2z = 0

4y - 2z = -2x

4y = -2x + 2z

To find y, divide both sides by 4:

4y = -2x + 2z

y = -1/2x + 1/2z

z:

First, isolate the variable you want to solve for:

To isolate z, add the inverses of x and y to both sides of the equation.

2x + 4y - 2z = 0

4y - 2z = -2x

-2z = -2x - 4y

To find z, divide both sides by -2:

-2z = -2x - 4y

z = x + 2y

To estimate the probability of hitting the bullseye at least 100 times in 2000 throws, we can use the binomial distribution formula. The probability of hitting the bullseye in a single throw can be calculated by finding the ratio of the areas of the bullseye and the entire dartboard.

The area of the bullseye (radius 1) is A_bullseye = π * 1^2 = π square units. The area of the entire dartboard (radius 5) is A_dartboard = π * 5^2 = 25π square units. Therefore, the probability of hitting the bullseye in a single throw is p = A_bullseye / A_dartboard = π / 25π = 1/25.

Now, we use the binomial distribution formula: P(X >= 100) = 1 - P(X < 100), where X is the number of bullseye hits. To calculate P(X < 100), we need to sum the probabilities from X = 0 to X = 99.

P(X < 100) = Σ [C(n, k) * p^k * (1-p)^(n-k)], for k = 0 to 99

Where n = 2000 (total throws), k = number of bullseye hits, and C(n, k) is the binomial coefficient (combinations of n elements taken k at a time).

Computing the above sum and subtracting it from 1 gives us the probability of hitting the bullseye at least 100 times. Due to the large number of calculations, using software or an online calculator can be helpful to compute this probability.

Answer:

13.82 or 14 people

Step-by-step explanation:

Step 1: Set equation equal to 7500

7500 = -25x² + 1250x - 5000

Step 2: Solve

0 = -25x² + 1250x - 12500

0 = -25(x² - 50x + 500)

0 = x² - 50x + 500

When you use the quadratic formula, you should get 13.82, rounded to 14 people as your answer.

Step-by-step explanation:

The perimeter of Max's sandbox is 21 feet.

The sum of each length of external sides or boundary of a given figure is called its perimeter. To determine the perimeter of an object, add up the length of its boundaries.

Given the dimension of the Ohio park, then we have to determine the representative fraction of Max's sandbox.

Representative fraction = 10/ 25

                                       = 2/ 5

So that;

x = 15 * 2/5

  = 6 ft

y = 12.5 *2/5

  = 5 ft

The perimeter of Max's sandbox = 10 + y + x

                                                      = 10 + 5 + 6

                                                      = 21 ft

The perimeter of Max's sandbox is 21 feet.
