Answer:

1.4 Inches Each

Step-by-step explanation:

This problem is fairly simple. Just divide 7 by 5 and put the correct units(inches) with the answer.

length of licorice each student will get is 1.875 inches.

A mathematical expression gets simpler when it is transformed into an equivalent, frequently shorter statement. One strategy for promoting uniformity in job effort, cost, and time is procedure simplification. It lessens diversity and variation that is harmful, unwanted, or unneeded.

Given, A licorice rope is 7 inches long. If four 5th graders share the licorice equally amongst themselves.

Since every 5th grader is sharing the rope equally.

Thus everyone will get = 7/4

Every 5th grader will get = 1.875 inches

Therefore, every 5th grader will get 1.875 inches length of licorice.

Answer:

the answer is 1,808.64 square miles

Answer:

53.38 sq. miles

Step-by-step explanation:

Area of a circle= πr²

Area = 3.14 * 17 = 53.38 sq. miles

Ship B is 22.8 km away from ship A on a bearing of N50°W.

The topmost point of the town hall is 28 metres above ground level.
The distance travelled by a point on the roundabout in one second is 113 cm for point A and 63 cm for point B.
Ship B is 22.8 km away from ship A on a bearing of N50°W.

Explanation:
1) For the first question, we can use trigonometry to find the height of the town hall. Let h be the height of the topmost point above ground level, and d be the distance between point A and the base of the town hall. Then we have:
tan(35°) = h/d and tan(60°) = h/(d-30)
Solving for h, we get:
h = d*tan(35°) and h = (d-30)*tan(60°)
Equating the two expressions for h, we get:
d*tan(35°) = (d-30)*tan(60°)
d = 30*tan(60°)/(tan(60°)-tan(35°)) ≈ 48.5 metres
Substituting back into the first equation, we get:
h = 48.5*tan(35°) ≈ 28 metres
Therefore, the topmost point of the town hall is 28 metres above ground level.

2) For the second question, we can use the formula for the circumference of a circle to find the distance travelled by a point on the roundabout in one second. The circumference of a circle is given by C = 2πr, where r is the radius of the circle. The distance travelled by a point in one second is then given by C/5, since the roundabout makes one revolution every five seconds. For point A, which is 1.8 metres from the centre of rotation, we have:
C = 2π*1.8 = 11.31 metres
Distance travelled in one second = 11.31/5 = 2.26 metres ≈ 226 cm ≈ 113 cm to the nearest centimetre
For point B, which is 1 metre from the centre of rotation, we have:
C = 2π*1 = 6.28 metres
Distance travelled in one second = 6.28/5 = 1.26 metres ≈ 126 cm ≈ 63 cm to the nearest centimetre

3) For the third question, we can use the law of cosines to find the distance between ship A and ship B. The law of cosines states that c^2 = a^2 + b^2 - 2ab*cos(C), where a, b, and c are the lengths of the sides of a triangle, and C is the angle opposite side c. Let x be the distance between ship A and ship B, and let θ be the angle between the two ships. Then we have:
x^2 = 17.2^2 + 14.1^2 - 2*17.2*14.1*cos(θ)
To find the angle θ, we can use the fact that the sum of the angles in a triangle is 180°. We have:
θ = 180° - 60° - 80° = 40°
Substituting back into the equation, we get:
x^2 = 17.2^2 + 14.1^2 - 2*17.2*14.1*cos(40°) ≈ 520.3
x ≈ 22.8 km
To find the bearing of ship B from ship A, we can use the law of sines. The law of sines states that a/sin(A) = b/sin(B) = c/sin(C), where a, b, and c are the lengths of the sides of a triangle, and A, B, and C are the angles opposite those sides. Let α be the bearing of ship B from ship A. Then we have:
14.1/sin(α) = 22.8/sin(40°)
Solving for α, we get:
α = sin^-1(14.1*sin(40°)/22.8) ≈ 30°
Since ship B is to the west of ship A, the bearing of ship B from ship A is N50°W.
Therefore, ship B is 22.8 km away from ship A on a bearing of N50°W.

Each item costs: 5.50 for a popcorn, 1.90 for a soda, and 2.50 for a hotdog.

An algebraic expression is the combination of numbers and variables in expressing and solving a particular mathematical question.

Let x = cost of a hotdog.

If popcorn costs 3 more than a hotdog, then

3 + x = cost of a popcorn.

If a soda costs 0.60 less than a hotdog, then

x - 0.60 = cost of a soda.

If a popcorn, a soda, and a hotdog at the movies is 9.90, then

(3 + x) + (x - 0.60) + x = 9.90

Simplify the equation and solve for the value of x.

(3 + x) + (x - 0.60) + x = 9.90

3 + x + x - 0.60 + x = 9.90

3x = 9.90 - 3 + 0.60

3x = 7.50

x = 2.50

cost of a hotdog = x = 2.50

cost of a popcorn = 3 + x = 3 + 2.50 = 5.50

cost of a soda = x - 0.60 = 2.50 - 0.60 = 1.90

After running the pump for 4 hours, the NTU measurement would be approximately 0.52.

To determine the NTU measurement after running the pump for 4 hours, we need to consider that the pump reduces the NTU by 10% each hour.

Here's the chart with the NTU values for each hour, rounded to the nearest hundredth:

Hours | NTU

0 | 0.80

1 | 0.72 (0.80 * (1 - 0.10) = 0.80 * 0.9)

2 | 0.65 (0.72 * (1 - 0.10) = 0.72 * 0.9)

3 | 0.58 (0.65 * (1 - 0.10) = 0.65 * 0.9)

37.5 degrees

we know angled like this always have 180 degrees total between the 2. which means we can set up a little equation to solve for x. The equation is (3x+22)+(x-4)= 180. Initially we can take the solid numbers (22 and -4) and get rid of them by taking them to the 180. 180- 22 is 158. 158 + 4 is 162. now we have 3x + x = 162. we combine like terms. means we end up with 4x =162. We now divide by 4 which means we get 40.5. Now we know x is 40.5. Now dbc is just 40.5- 4 which is 37.5.

The measure of angle ∠DBC is,

⇒ ∠DBC = 35.5°

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

Point D is in the interior of ∠ABC.

And, ∠ABD = (3x + 22)°

⇒ ∠DBC = (x - 4)°

Clearly, Both angle make a linear pair.

Hence, We get;

⇒ ∠ ABD + ∠DBC = 180°

⇒ (3x + 22) + (x - 4) = 180°

⇒ 3x + 22 + x - 4 = 180

⇒ 4x + 18 = 180

⇒ 4x = 180 - 18

⇒ 4x = 162

⇒ x = 162/4

⇒ x = 40.5

Hence, The measure of angle ∠DBC is,

⇒ ∠DBC = (x - 4)°

⇒ ∠DBC = (40.5 - 4)°

⇒ ∠DBC = 35.5°

The mode is best used as a measure of central tendency when dealing with nominal data, ordinal data where only the most frequent score is of interest, or unimodal distributions with skewed data.

The mode, like the median and mean, is one of the measures of central tendency that is used in statistics. However, when is it best to use the mode as a measure of center?

What is the mode? The mode is the most frequently occurring value in a set of observations. If a dataset includes many repeated values, then it has a high mode, whereas if it does not include repeated values, it has no mode. The mode is most useful for nominal and ordinal data when the central value or typical value is most frequent.

When is it best to use the mode as a measure of center? The mode should be used as a measure of central tendency in the following cases:

For example, when you ask people to rate their experience at a restaurant on a scale of 1 to 5 (1 = worst experience, 5 = best experience), the data is ordinal. However, if you only want to know the most frequent rating, the mode is the best measure of central tendency.

There is sufficient evidence to conclude that the population mean is not 22°C.

We can use a one-sample t-test to test the claim that the population mean is 22°C. The null and alternative hypotheses are

H0: μ = 22 (the population mean is 22°C)

Ha: μ ≠ 22 (the population mean is not 22°C)

We can use a t-distribution with 59 degrees of freedom to calculate the test statistic and p-value. The test statistic is:

t = (X - μ) / (σ / √n) = (20 - 22) / (1.5 / √60) = -6.708

Using a t-table or calculator, we can find the p-value associated with this test statistic, which is less than 0.0001 (very small).

Since the p-value is less than the significance level of 0.05, we reject the null hypothesis.

The angles that make up a kite are 1, 2, 3, 4, 5, 6, and 7. Angle 1 is the interior angle between sides 1 and 2. Angle 2 is the interior angle between sides 2 and 3.

Angle 3 is the interior angle between sides 3 and 4. Angle 4 is the exterior angle between sides 4 and 1. Angle 5 is the interior angle between sides 1 and 3. Angle 6 is the exterior angle between sides 2 and 4. Angle 7 is the interior angle between sides 2 and 4.

An angle is a figure formed by two lines that meet at a common point. The lines are called the arms of the angle, and the common point is called the vertex. Angles are usually measured in degrees, with a full circle being 360°.

A kite is a four-sided geometric shape with two pairs of adjacent equal-length sides. The missing values for each angle in the kite can be calculated using the formula:

Angle 1 + Angle 2 + Angle 3 + Angle 4 + Angle 5 + Angle 6 + Angle 7 = 360 degrees

For example, if angle 1 is 60 degrees, then angle 2 = 120 degrees, angle 3 = 120 degrees, angle 4 = 60 degrees, angle 5 = 120 degrees, angle 6 = 60 degrees, and angle 7 = 60 degrees.

In general, the sum of the interior angles of a kite will equal 360 degrees, and each interior angle will be equal to the sum of the exterior angles. Therefore, if the values of four of the angles are known, the remaining angles can be calculated by subtracting the known angles from 360 degrees.

The number of different ways the festival director can hire seven of the ten interns can be calculated using combinations.  To find the number of combinations, we can use the formula for combinations: nCr = n! / (r!(n-r)!)

Where n represents the total number of interns (10 in this case) and r represents the number of interns the festival director wants to hire (7 in this case). Let's calculate the number of combinations: 10C7 = 10! / (7!(10-7)!) First, we calculate the factorial of 10: 10! = 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 Next, we calculate the factorial of 7: 7! = 7 x 6 x 5 x 4 x 3 x 2 x 1 Finally, we calculate the factorial of (10-7): (10-7)! = 3 x 2 x 1

Now, let's substitute these values into the formula:
10C7 = 10! / (7!(10-7)!)
= (10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1) / (7 x 6 x 5 x 4 x 3 x 2 x 1 x 3 x 2 x 1)
= (10 x 9 x 8) / (3 x 2 x 1)
= 720 / 6
= 120
Therefore, there are 120 different ways the festival director can hire seven of the ten interns.
