Answer:

22.86 meters

Step-by-step explanation:

you find out how much is a meter which is 0.9144 now you multiply by how much yards you have and you get 22.86 meters

On converting 25 yards to meters the value is obtained as 22.86 meters.

What is length?

The measurement or size of something from end to end is referred to as its length. To put it another way, it is the greater of the higher two or three dimensions of a geometric shape or object. For instance, the length and width of a rectangle define its dimensions. In the International System of Quantities, length is also a quantity with the dimension distance.

The base unit for length in the International System of Units (SI) system, is the metre and it is abbreviated as m.

Other units include mm, cm, km, inches, yards etc.

The formula for converting yards to meters is -

1 yard = 0.9144 meter

The length in yards is given as - 25 yards

Substitute the values in the equation -

Length in meter = Length in yard × 0.9144

Length in meter = 25 × 0.9144

Length in meter = 22.86 m

Therefore, the length in meter is 22.86 meters.

Duncan is approximately 10.8 kilometers away from his grandparents' house, if necessary, rounding to the nearest tenth.

Based on the given information, we can use the Pythagorean theorem to find the distance between Duncan's house and his grandparents' house. The theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
In this case, the distance from Duncan's house to his parents' house (6 km) and the distance from his parents' house to his grandparents' house (9 km) form the two shorter sides of the triangle. To find the distance between Duncan's house and his grandparents' house, we will calculate the hypotenuse:
h² = 6² + 9²
h² = 36 + 81
h² = 117
h ≈ 10.8

A chocolate chip cookie manufacturing company recorded the number of chocolate chips in a sample of 50 cookies. The mean is 23.33 and the standard deviation is 2.6. Construct a 80% confidence interval estimate of the standard deviation of the numbers of chocolate chips in all such cookies.

Solution

Given  

n=50

x=23.33

s=2.6

Alpha = 1-0.80 = 0.20  

X^2(a/2,n-1) = X^2(0.10, 49) = 63.17

sqrt(63.17) = 7.948

X^2(1 - a/2,n-1) = X^2(0.90, 49) = 37.69

sqrt(37.69) = 6.139

s*sqrt(n-1) = 18.2

15 V64 88.14 V64.8 81 2 3. 814 64 o V64 . 3. 814 15 2 V64, 814 8​

Step-by-step explanation:

6.  At the end of 15 minutes, the two trains are approximately 58.71 miles apart.

7.The inclined distances from the balloon to each observer is 16.659 km for first observer and 32.1675 km for second observer

8.  The time in the Philippines, located 120° east longitude, is 8:00 am GMT + 8 hours, which is 4:00 pm local time.

9.  The area of the spherical triangle is 15.2725 square meters.

10. Side b in the right spherical triangle is approximately 50.951°.

6. We can use the law of cosines to find the distance between the two trains after 15 minutes. The law of cosines states:

c^2 = a^2 + b^2 - 2ab * cos(C)

a = 45 mph

b = 52 mph

C = 36 degrees

Converting the time to hours:

15 minutes = 15/60 = 1/4 hour

Using the formula, we can calculate the distance:

c^2 = (45 mph)^2 + (52 mph)^2 - 2 * 45 mph * 52 mph * cos(36 degrees)

c^2 = 2025 + 2704 - 4680 * cos(36 degrees)

c^2 = 4729 - 4680 * cos(36 degrees)

c^2 ≈ 3443.28

Taking the square root of both sides:

c ≈ √3443.28

c ≈ 58.71 miles

7.  Using trigonometry, we have:

tan(48°) = x / 15 (angle of elevation for the first observer)

tan(61°) = y / 15 (angle of elevation for the second observer)

Rearranging the equations, we get:

x = 15 * tan(48°)

y = 15 * tan(61°)

Calculating these values:

x ≈ 15 * 1.1106 ≈ 16.659 km

y ≈ 15 * 2.1445 ≈ 32.1675 km

8. The Earth rotates 360° in 24 hours, which means that each degree of longitude corresponds to 4 minutes of time difference.

120° * 4 minutes = 480 minutes

480 minutes / 60 = 8 hours

9. To calculate the area of a spherical triangle, we can use the formula:

Area = (A + B + C - π) * r^2

Converting the given angles to radians:

A = 40° * (π/180) ≈ 0.6981 rad

B = 65° * (π/180) ≈ 1.1345 rad

C = 110° * (π/180) ≈ 1.9199 rad

Substituting the values into the formula:

Area = (0.6981 + 1.1345 + 1.9199 - π) * 5^2

= (3.7525 - 3.1416) * 25

=0.6109 * 25

≈ 15.2725 square meters

10. In a right spherical triangle, the side opposite the right angle (side c) is the hypotenuse, and the remaining sides are labeled as a and b.

Given: C = 90°, a = 50°, and c = 80°.

To find side b, we can use the spherical Law of Sines:

sin(a) / sin(A) = sin(b) / sin(B)

Plugging in the values:

sin(50°) / sin(90°) = sin(b) / sin(80°)

Since sin(90°) = 1, we have:

sin(50°) = sin(b) / sin(80°)

Rearranging the equation:

sin(b) = sin(50°) * sin(80°)

Taking the inverse sine of both sides:

b = arcsin(sin(50°) * sin(80°))

Evaluating the expression:

b ≈ arcsin(0.7660 * 0.9848)

b ≈ arcsin(0.7546)

b ≈ 50.951°

Answer:

The largest number is 190.

Step-by-step explanation:

Given that,

Two whole numbers add up to 337 and their difference 43.

Let two whole number is x and y.

The sum of two whole number is

\(x+y=337\)

The difference of two whole number is

\(x-y=43\)

We need to calculate the numbers

Using equation (I) and (II)

\(x+y=337\)

\(x-y=43\)

Now, add the equations

\(2x=380\)

\(x=\dfrac{380}{2}\)

\(x=190\)

Put the value of x in equation (I)

\(190+y=337\)

\(y=337-190\)

\(y=147\)

The numbers are 190 and 147.

Hence, The largest number is 190.

Management by objectives (MBO) is a management system that incorporates goal setting as its central principle.

It emphasizes the establishment of clear, measurable objectives for individuals and teams within an organization, aligning their efforts with overall organizational goals and strategies. MBO provides a framework for performance management and evaluation, allowing managers and employees to work together to define objectives, set targets, and track progress towards achieving those goals.

The goal-setting aspect of MBO is supported by various theories and principles. Firstly, the concept of goal setting itself is a fundamental component of MBO. It is based on the idea that setting specific, challenging, and attainable goals can motivate individuals and enhance performance. The expectancy theory comes into play as well, as MBO assumes that individuals are motivated to achieve their goals when they believe that their efforts will lead to successful performance and desired central outcomes.

Additionally, cognitive dissonance theory suggests that MBO can help reduce cognitive dissonance by providing individuals with clear objectives and performance expectations, minimizing conflicts between their attitudes and behaviors. While hedonism and equity theory are not directly incorporated into MBO, they may indirectly influence individuals' motivation and satisfaction as they work towards their objectives within the MBO framework.

In summary, Management by Objectives (MBO) is a management system that revolves around goal setting. It incorporates various theories and principles such as goal setting theory, expectancy theory, and cognitive dissonance theory. By setting clear objectives, aligning efforts, and tracking progress, MBO provides a structured approach to performance management and encourages individuals and teams to work towards achieving organizational goals.

To approximate the change in volume of a spherical balloon as the radius increases from 8m to 8.2m, we can use differentials. The volume of a sphere is given by the formula V = (4/3)πr^3.

Taking differentials of both sides, we have dV = 4πr^2 dr.

At r = 8m, we have dV ≈ 4π(8m)^2 (0.2m) ≈ 160π/3 m^3.

Therefore, the change in volume of the spherical balloon as the radius increases from 8m to 8.2m is approximately 160π/3 m^3.
To approximate the change in volume of a spherical balloon using differentials, we'll use the formula for the volume of a sphere (V) and differentiate it with respect to the radius (r):

V = (4/3)πr³

Now, let's differentiate V with respect to r (dV/dr):

dV/dr = d((4/3)πr³)/dr = (4πr²)

Next, we'll find the differential change in radius (dr) which is the difference between the initial radius and the final radius:

dr = 8.2 m - 8 m = 0.2 m

Now, we can approximate the change in volume (dV) using differentials:

dV ≈ (dV/dr) * dr = (4πr²) * dr

Plug in the given values of r = 8 m and dr = 0.2 m:

dV ≈ (4π(8)²) * (0.2) = (4π(64)) * (0.2) = 51.2π m³

So, the approximate change in volume of the spherical balloon as it swells from a radius of 8 m to 8.2 m is 51.2π m³.

Answer:

$80,000

Step-by-step explanation:

Define the variables:

Let x =  "fish-flavored" chicken company investment (in dollars)

Let y = spray-on vitamins company investment (in dollars)

If Allen invested a total of $100,000:

⇒ x + y = 100000

Given:

⇒ 0.03x + 0.01y = 2600

Rewrite the first equation to make y the subject:

⇒ y = 100000 - x

Substitute into the second equation and solve for x:

⇒ 0.03x + 0.01(100000 - x) = 2600

⇒ 0.03x + 1000 - 0.01x = 2600

⇒ 0.02x + 1000 = 2600

⇒ 0.02x = 1600

⇒ x = 80000

Therefore, Allen invested $80,000 in the "fish-flavored" chicken company.

Therefore, based on the information given, it seems that Bus Company A is doing slightly better in terms of on-time performance.

To determine which bus company seems to be doing better, we need to compare their on-time performance.

Bus Company A claims that it is typically on time 95% of the time. This means that out of 100 trips, it expects to be on time for 95 of them.

On the other hand, Bus Company B has a record of being on time 47 days out of the 50 days that it operates. This means that its on-time performance is:

47/50 = 0.94 or 94%
