The Mt. Aconcagua is 22,834ft tall and Mount Everest is 29,035 feet tall. And he climbed both mountains in two years how many feet of mountains did he climb

The simple interest after three years is ₹2625 and the total amount is ₹14,375.

To find the simple interest and total amount after three years, we can use the formula:

Simple Interest = Principal × Rate × Time

Total Amount = Principal + Simple Interest

Given that the Principal is ₹11,750 and the Annual Rate of Interest is 7.5%, we can calculate the Simple Interest by substituting these values into the formula:

Simple Interest = ₹11,750 × 0.075 × 3

After calculating, we find that the Simple Interest is ₹2625.

To find the Total Amount, we can use the formula:

Total Amount = Principal + Simple Interest

Substituting the values into the formula, we get:

Total Amount = ₹11,750 + ₹2625

After calculation, the Total Amount is ₹14,375.

Answer:

a(n) = 130 + (n-1) 13

13th term = 286

Step-by-step explanation:

We are given a sequence of numbers: 130, 143, 156, 169, ... and we are to write an explicit formula to represent the arithmetic sequence and use it to find the 13th term.

We know that the arithmetic sequence can be defined by:

[tex]a_n=d(n-1)+c[/tex]

where [tex]d[/tex] = the common difference between consecutive terms ; and

[tex]c[/tex]=[tex]a_1[/tex]

13th term:

[tex]a_{13}=130+(12)13 = 286[/tex]

Therefore, the formula for this sequence will be a(n) = 130 + (n-1) 13 and 13th term is 286.

Answer:

YES

Step-by-step explanation:

First, let's find the total number of seats int he airplane.

14 + 64 + 4 * 108 = 510

The airplane has a total or 510 seats.

Half of the number of seats is 510/2 = 255.

Now let's calculate the number of seats being used and compare with 255.

5/7 * 14 + 5/16 * 64 + 5/9 * 4 * 108 =

= 2 * 5 + 4 * 5 + 12 * 4 * 5

= 10 + 20 + 240

= 270

270 seats are being used.

270 is greater than 255, so more than half of the seats are being used.

18.84 (or 19 to 2.s.f)

Step-by-step explanation:

The formula for the circumference of a circle is π * diameter. To find the diameter you multiply the radius by 2:

3 * 2 = 6

Then simply plug the value into the formula:

π * 6 = 6π ≈ 18.84 ≈ 19 to 2.s.f

Answer:The answer is 18.84

Step-by-step explanation:To figure out the circumference of a circle you need to divide the radius by 2. After that you would do [tex]2\pi * ( your number )[/tex] * 2

Answer:

16.5 inches

Step-by-step explanation:

WE have arc length formula for a circle as

Arc length = [tex]\frac{x}{360} (2\pi r)[/tex]

where x is the central angle the arc subtends at the centre.

Here x = 135

r= 7 inches

Hence arc length

=[tex]\frac{135}{360} (2\pi )(7) =16.5"[/tex]

Hence option B

16.5 inches is right answer for arc length for a circle of radius 7 inches.

The measure of length of arc AB is 16.5 inches. Therefore, option B is the correct answer.

An arc of a circle is a section of the circumference of the circle between two radii. A central angle of a circle is an angle between two radii with the vertex at the centre. The central angle of an arc is the central angle subtended by the arc. The measure of an arc is the measure of its central angle.

Given that, the radius of the circle is 7 inches and measure of arc AB is 135°.

Let O be the center of circle.

So, ∠AOB=135°

We know that, arc length of circle is θ/360° ×2πr

= 135°/360° ×2×3.14×7

= 0.375×2×3.14×7

= 16.485

≈ 16.5 inches

Therefore, the approximate length of AB is 16.5 inches.

Step-by-step explanation:

Y=cos(x+r/2)

Answer:

[tex]y=cos(x+\pi )[/tex]

Step-by-step explanation:

From the graph, we can see that y = -1 when x  = 0.

So to check whether which of the given options is the equation of the given graph, we will set our calculator to the radian mode and then plug the value of x as 0.

1. y = cos(x + pi/2) = cos(0 + pi/2) = 0

2. y = cos(x+2pi) = cos(0+2pi) = 1

3. y = cos(x+pi/3) = cos(0+pi/3) = 1/2 = 0.5

4. y = cos(x+pi) = cos(0+pi) = -1

Therefore, the equation of this graph is y = cos(x+pi) = cos(0+pi) = -1.

The problem where one number is 7 more than another and their squares differ by 217 can be solved by creating a system of equations and simplifying to find the numbers are 12 and 19.

To solve the problem where one number is 7 more than another and the difference between their squares is 217, we can create a system of equations. Let's assume the first number is x and the second number is x+7. The problem then translates to the equation (x+7)² - x² = 217.

Step-by-step solution:

After computing the solution, we find that the two numbers are 12 and 19.

Answer:

Step-by-step explanation:  Pru, Piper, Phoebe their ratio 5:3:4 added = 12

What this would mean is that Pru has 5/12 of the total amount, Piper has 3/12 of the total, and Phoebe has 4/12 of the total amount of spices all together.

pru = piper + 24

5/12x = 3/12x + 24

5/12x - 3/12x = 24

2/12x = 24

x = 24 / (1/6)

x = 24 * 6

x = 144 spices in all.

Pru has : 5/12(144) = 720/12 = 60 spices

Piper has : 3/12(144) = 432/12 = 36 spices

Phoebe has : 4/12(144) = 576/12 = 48 spices <====

Answer:

48 spices

Step-by-step explanation:

The number of spices each has is a multiple of 5, 3, and 4.

The number of spices each has is 5x, 3x, and 4x.

Pru has 5x spices.

Piper has 3x spices.

Pru has 24 more spices than Piper, so

5x = 3x + 24

2x = 24

x = 12

Phoebe has 4x spices, so Phoebe has

4(12) = 48

Our first step is the find the lcm of 4 and 12 so we can add the two fractions without having a problem.

The lcm of 4 and 12 is clearly 12 because 12 is a multiple of 4. 12 divided by 4 is 3, so you must multiply by 3/3 to be able to add the two fractions.

1/4*(3/3)=3/12.

So, 3/12+5/12=7/12.

Final answer:

A formula to determine Seth's weekly lunch expense is Weekly Spending = n × 5, where n represents the new price of lunch and the multiplication by 5 accounts for each day of the school week.

Explanation:

To help Seth determine how much he'll now spend on lunch every week, we need to create a formula that takes into account the new price of a lunch and the frequency of his purchases. Let's assume the new price of a lunch is represented by the variable n. Since Seth buys lunch 5 days a week, the formula to calculate his weekly spending will be Weekly Spending = n × 5. This formula can be used to multiply the new price of a lunch (n) by 5, giving Seth the total amount he will spend each week on school lunches.

Hi There!

Answer:

B) 28

Step-by-step explanation:

y = 12 and x = 14 are both proportional.

y = 24 and x = ? are both proportional.

You notice that 24 is twice as much as 12 so we do the same with x.

14 * 2 = 28

They are both proportional when y = 24 and x = 28.

Hope This Helps :)

Answer:

B) 28

Step-by-step explanation:

The equation for direct proportion is

y= kx

If y =12 and x =14

12 = k * 14

Divide each side by 14

12/14 = k

Simplifying

6/7 =k

y =6/7 x

Now if y =24

24 = 6/7 x

Multiply each side by 7/6 to isolate x

24 * 7/6 = 7/6 * 6/7 x

28 =x

Answer:

y = 3x - 18

Step-by-step explanation:

The given line, y = -3x + 9, has slope -3.  Any new line perpendicular to this has slope +3/1, or just 3.

Start with the general slope-intercept form of the equation of a straight line:

y = mx + b.  Now substitute 9 for y, 9 for x and 3 for m:

9 = 3(9) + b.  Then b = -18, and the desired equation is y = 3x - 18.

The equation of the line perpendicular to y = -3x + 9 that passes through the point (9,9) is y = ([tex]\frac{1}{3}[/tex])x + 6.

The question is asking to find the equation of a line in slope-intercept form that is perpendicular to the given line y = -3x + 9 and passes through the point (9,9). To find the equation of a line that is perpendicular to the given line, we need to determine the slope of the new line. The slope of any line perpendicular to a line with a slope of m is [tex]-\frac{1}{m}[/tex]. Since the given line has a slope of -3, the slope of the perpendicular line will be [tex]\frac{1}{3}[/tex]. Now using the point-slope form of a line, which is y - y₁ = m(x - x₁), where (x₁, y₁) is a point on the line and m is the slope, we can write the equation of the new line through the point (9,9) as y - 9 = ([tex]\frac{1}{3}[/tex])(x - 9). Simplifying this equation gives us y = ([tex]\frac{1}{3}[/tex])x + 6, which is in slope-intercept form y = mx + b where m is the slope and b is the y-intercept of the line.
