Now,

a)

Opposite angles are congruent:

So,

5x + 29 = 7x - 11

29 + 11 = 7x - 5x

40 = 2x

Find all pairs of positive integers (a,n) such that n greater than 2 and a + (a + 1) + (a + 2) + ... + (a + n - 1) = 100.

Answers

(49,5), (19,10), (9,20), (4,50), (1,100) are the only pairs of positive integers (a,n) such that n is greater than 2 and a + (a + 1) + (a + 2) + ... + (a + n - 1) = 100.

In mathematics, an integer is a number that can be written without a fractional or decimal component.

To start, we can use the formula for the sum of an arithmetic series to find the value of n.

The formula for the sum of n terms in an arithmetic series is given by

=> S = n/2 (a + a + n - 1),

where a is the first term and n is the number of terms. Substituting the values from the problem, we have:

=> 100 = n/2 (2a + n - 1)

Expanding the right side, we get:

100 = n/2 (2a + n - 1)

Multiplying both sides by 2 and rearranging, we get:

200 = n (a + n/2)

Dividing both sides by n, we get:

a + n/2 = 200/n

Since n is an integer greater than 2, we know that n must divide 200. To find all possible values of n, we can use the divisibility rule for 2, which states that an integer is divisible by 2 if and only if its last digit is 0, 2, 4, 6, or 8. Thus, we can list all possible values of n as follows:

=> n = 2, 4, 5, 8, 10, 20, 25, 40, 50, 100

For each value of n, we can use the formula for a to find all possible values of a that satisfy the conditions of the problem. Substituting n = 2 into the formula for a, we get:

=> a + n/2 = 200/n

=> a + 1 = 200/2

=> a = 199/2

Since a is a positive integer, we see that a = 199/2 is not an integer, so the pair (a,n) = (199/2,2) is not a solution. Continuing this process for each value of n, we find the following pairs of positive integers (a,n) that satisfy the conditions of the problem:

=> (a,n) = (49,5), (19,10), (9,20), (4,50), (1,100)

You decide to make an investment in bonds. After much deliberation, you decide to purchase 10 State Farm bonds at a price of 99.40. These bonds have a 5% interest paid annually.

• How much did you pay for the 10 bonds (excluding commission)?
• How much interest will you receive each year from the bonds?
• What is your bond yield (to the nearest tenth percent)?

Answers

The bond yield is approximately 5.0% to the nearest tenth of a percent.

We have,

To find the total cost of the 10 State Farm bonds, we can multiply the price per bond by the number of bonds:

10 bonds x $99.40 per bond = $994.00

So, we paid $994.00 for the 10 State Farm bonds.

To calculate the amount of interest we will receive each year from the bonds, we can use the following formula:

Interest = Principal x Rate

where:

The principal is the amount invested in the bonds

Rate is the interest rate

In this case, our principal is $994.00 and our rate is 5%, or 0.05 as a decimal.

So, the annual interest we will receive from the bonds is:

Interest = $994.00 x 0.05 = $49.70

So,

We will receive $49.70 in interest each year from the bonds.

To calculate the bond yield, we need to use the following formula:

Bond yield = (Annual interest / Total cost) x 100%

In this case, the annual interest is $49.70 and the total cost is $994.00, so we can plug these values into the formula:

Bond yield = ($49.70 / $994.00) x 100% ≈ 5.0%

Therefore,

The bond yield is approximately 5.0% to the nearest tenth of a percent.

Andrew wants to build a square garden and needs to determine how much area he has for planting the perimeter

Answers

Answer:

9 ft^2 and 12.25 ft^2

Step-by-step explanation:

We need to figure out the area for a square with a perimeter of 12 feet and 14 feet.

A square has four sides that are all equal in length, therefore:

12/4 = 3

14/4 = 3.5

3 and 3.5 are the individual side lengths of the garden, so to find the area, we just multiply those numbers by themselves (since it is a square garden).

3*3 = 9

3.5*3.5 = 12.25

10. Prime numbers from 1 to 100 are running a restaurant - PRIME SPOT, near a tourist point. On a winter holiday, 1 and the composite numbers up to 100 enter the restaurant for dinner after their picnic at the same point. The dining hall has tables with seating capacity 15 for each. If they occupy tables without leaving any chair free, how many tables are required? If each prime number attender has to serve equal number of customers, how many customers should each one get to serve? ​

Answers

6 tables are required. Each prime number attender should serve 3 customers each.

The prime numbers between 1 and 100 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.

All the numbers other than prime numbers are composite numbers.

The composite numbers from 1 to 100 are: 1, 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100.

Now, as there are 25 primes and 75 composites in the group that visited the restaurant, we can calculate the number of tables required by dividing the number of people by the seating capacity of each table.

Each table has a seating capacity of 15, so the number of tables required will be: Number of tables = (Number of customers)/(Seating capacity of each table)Number of customers = 25 (the number of primes) + 75 (the number of composites) = 100Number of tables = 100/15 = 6 tables

Therefore, 6 tables are required.

Now, as each prime number attender has to serve an equal number of customers, we need to calculate how many customers each one should serve.

Each prime attender has to serve 75/25 = 3 customers each, as there are 75 composites and 25 primes.

Thus, each prime number attender should serve 3 customers each.

The value of x is 12.82, the value of z is 40.25.

Using Pythagorean theorem

50²= 39² + y²

y²= 2500- 1521

y= 32.28

Again Using Pythagorean theorem

z²= y²+ x²

z²- x²= 979

and, (39 + x)² = 50² + z²

(39 + x)² = 50² + (x² + 979)

1521 + 78x + x² = 2500 + x² + 979

78x = 1000

x ≈ 12.82

Substituting this value of x back into the first equation, we get:

z² - x² = 979

z² - (12.82)² = 979

z² ≈ 1620.12

Taking the square root of both sides, we get:

z ≈ 40.25

Therefore, the value of x is 12.82, the value of z is 40.25.

SCENARIO #4 - Christian's Cart Experiment In this exercise you will read the following scenario and identify the parts of the scientific method in it. Christian wonders if a heavier cart will roll faster down-hill than a lighter one. He formulates a hypothesis and then decides to conduct an experiment. First, he finds a smooth ramp and a cart. He makes sure that the wheels of his cart roll freely. He set the ramp against a chair so one side of the ramp was 0.5 m off the ground. Next, he measures the distance the cart will travel down the ramp. He leaves about 10 cm at the top of the ramp and draws a line to mark the release position of the car. He then measures the distance the cart will travel down the ramp and has a stopwatch to time how long it will take to reach the bottom of the ramp. He starts the experiment by measuring the time it takes the cart to roll down the hill without any weight on it. For the next five trials he adds a 1 kg mass to the cart each trial. The times of the trials were 1- 27s, 2- 32s, 3- 30s, 4- 29s, 5- 30s. When comparing the data points, he decides to allow for a 5 second "fudge factor" since he may not have released the cart at precisely the exact same spot each time. He finds that adding mass to the cart does not affect the time it takes to roll down the ramp since all of his times were within 5 seconds of each other. 1.
