The ladder can reach 21.17 feet high up of Denise's house.

Given,

The length of ladder Denise used to clean the outside of her second story windows = 24 feet

The distance between the base of the ladder and house = 13 feet

We have to find the height of the house which the ladder can reach:

For that we can use Pythagorean Theorem.

That is,

Hypotenuse² = Altitude² + Base²

Here,

Hypotenuse is the length of the ladder = 24 feet

Altitude is the height of the house ladder can reach = x

Base is the distance between base of the ladder and house = 13 feet

Therefore,

24² = x² + 13²

576 = x² + 169

x² = 576 - 169

x² = 407

x = [tex]\sqrt{407}[/tex]

x = 21.17

That is, the ladder can reach 21.17 feet high up of Denise's house

Probability:

Probability refers the fraction of favorable event by the total number of event.

Given,

A bag contains one tile for each letter of the word TRAINS.

Here we need to find If we selected a permutation of these letters at random, what is the probability that they would spell TRAINS.

We know that,

There are 6 letters in the word and the number of arrangements is the permutation of 6 taken 6 at a time.

So, it is written in permutations as,

y = 3.5x is the equation that represents y, the total number of hours Tonya works in x days if she continues at the given rate.

Unitary method is a concept in which the value of a single unit is first found out and then multiplied by the necessary value to get the required answer.

Here, we are given that Tonya works 3.5 hours in 1 day.

The total number of days = x

and the total number of hours Tonya works in x days = y

If she works for 3.5 hours in 1 day, in x days she will work-

x x 3.5

= 3.5x hours

Thus, y = 3.5x hours

Hence, y = 3.5x is the equation that represents Tonya's situation.

The solution of the equation is  (-3, 6).

-3c - 3y = -9

5c - 2y = -27

Therefore, using elimination method, the equation can be solved as follows:

multiply equation(ii) by 1.5(3  /2)

-3c - 3y = -9

7.5c - 3y = - 40.5

subtract equation(i) from equation(ii)

10.5c = - 31.5

divide both sides by 10.5

c = -31.5 / 10.5

c = -3

Therefore,

5c - 2y = -27

5(-3) - 2y = -27

-15 - 2y = -27

-2y = -27 + 15

-2y = - 12

divide both sides by -2

y = -12 / -2

y = 6

Step-by-step explanation:

Carter needs to ride 3.9 miles per day on an average to meet his target of riding 28.7 miles in a week.

We are given that:

The total number of miles that needs to be ridden by Carter = 28.7 miles

Now, he has already ridden 17 miles this week

So, the miles left to be ridden = 28.7 miles - 17 miles

Number of miles left = 11.7 miles.

Now, he has 3 more days to finish his target.

So, on an average, he should ride:

Average = 11.7 miles / 3 days = 3.8 miles per day

Therefore, Carter needs to ride 3.9 miles per day on an average to meet his target of riding 28.7 miles in a week.

Find algebraically y values for x = -2 and x = 2 and connect the two points by a line

Equation: y = 3x + 2

For x = -2, y = 3(-2) + 2 = -6 + 2 = -4

For x = 2, y = 3(2) + 2 = 6 + 2 = 8

So the two points are (-2, -4) and (2, 8)

Answer:

Step-by-step explanation:

Use the Pythagorean theorem:

a^2+b^2=c^2

(You have to count the distance of x and y, then plug those number in the formula)

0^2+8^2=c^2

64=c^2

square root it

8=c

You can also use the distance formula

It is true that 8 > 2 is unequal.

Divide both sides by 2, then:

True inequality also exists when 4 > 1. Due to the fact that we divided by a positive number, the inequality symbol remained.

-4 > -1 is erroneous. The inequality is no longer valid if the inequality sign changes when both sides are divided by a negative integer. When dividing both sides by a negative integer, the inequality sign must be changed in order to maintain its validity.

The value of x is 18° and the value of the angles A and B are 73° and 107° respectively.

We are given the angle measurements as:

A = (6x - 35)°

B = (3x + 53)°

We need to solve for x and find the values of A and B

We know that co- interior angles are supplementary.

So, we get that:

A + B = 180°

Substituting the values of A and B in the above equation, we get that:

6 x - 35 + 3 x + 53 = 180

9 x + 18 = 180

9 x = 180 - 18

9 x = 162

x = 162 / 9

x = 18

So, we now get that:

A = (6x - 35)°

A = (6(18) - 35)°

A =(108 - 35)°

A = 73°

B = (3 x + 53)°

B = (3 (18) + 53)°

B = ( 54 + 53 )°

B = 107°

Therefore, we get that the  value of x is 18° and the value of the angles A and B are 73° and 107° respectively.

* Lets  explain how to solve the problem

- In week 10 the manufacturer fixed 200 cars

- In week 15, the manufacturer fixed 175 cars

- the reduction in the number of cars each week is linear

- The form of the linear equation is y = mx + c, where m is the slope of

the line which represent the equation and c is the y-intercept

- The slope of the line m =

 where (x1 , y1) and (x2 , y2) are two points on the line

* Lets solve the problem

- Assume that the weeks' number is x and the cars' number is y

∴ (10 , 200) and (15 , 175) are two points on the line which represent

 the linear equation between the cars' numbers and the weeks

 numbers

∵ Point (x1 , y1) is (10 , 200) and point (x2 , y2) is (15 , 175)

∴ x1 = 10 , x2 = 15 and y1 = 200 and y2 = 175

- Use the rule of the slope above to find m

∴

- Substitute the value of x in the form of the linear equation above

∴ y = -5x + c

- To find c substitute x and y by one the coordinates of one of the

 two points

∵ x = 10 when y = 200

∴ 200 = -5(10) + c

∴ 200 = -50 + c

- Add 50 to both sides

∴ 250 = c

- Substitute the value of c by 250

∴ y = -5x + 250, where the number of cars seen each week is y and

 x is the number of the week

∵ f(x) = y

∴ f(x) = -5x + 250

Sn = a(1 - rⁿ)/(1 - r) is the formula for the sum of a finite number of terms in a geometric series, where is the number of terms, is the first term, and is the common ratio.

The sum of the finite geometric series Σ⁴ n=1 (1/2)ⁿ⁺¹ is 0.46875.

The equation be Sn = a(1 - rⁿ)/(1 - r), where s exists the total, a1 exists the series first term, and r exists the common ratio, is a general formula for estimating the sum of an finite geometric series. The formula a2/a1, where a2 is the second term in the series and a1 is the first term in the series, can be used to determine the common ratio.

Let the sum of the finite geometric series be Σ⁴ n=1 (1/2)ⁿ⁺¹

Σ⁴ n=1 (1/2)ⁿ⁺¹ = (1/2)¹⁺¹ + (1/2)²⁺¹ +(1/2)³⁺¹ + (1/2)⁴⁺¹

simplifying the above equation, we get

= (1/2)² + (1/2)³ + (1/2)⁴ + (1/2)⁴⁺¹

= (1/4) + (1/8) + (1/16) + (1/32)

Where, the first term is a = 1/4

common ratio be r = 1/2

n th term be n = 4

Let the equation be Sn = a(1 - rⁿ)/(1 - r)

substitute the values in the above equation, we get

S4 = (1/4) (1-(1/2)⁴) / (1 - (1/2))

simplifying the above equation, we get

S4 = (1/4) (15/16) × 2 = 15/32 = 0.46875

Therefore, the sum of the finite geometric series Σ⁴ n=1 (1/2)ⁿ⁺¹ is 0.46875.
