The object that has a capacity that is best measured in pints is the water bottle.Pints are commonly used to measure smaller volumes of liquids, such as beverages.

Water bottles are typically used to hold and carry liquids, including water and other beverages. They are designed to have a capacity suitable for personal use and are often labeled with their volume in pints or fluid ounces.

On the other hand, the other objects mentioned have larger capacities that are not typically measured in pints:

A soup spoon is a utensil used for eating soup and has a capacity measured in teaspoons or tablespoons, not pints.

A trash barrel is a larger container used for holding garbage or waste and is usually measured in gallons or liters, not pints.

A swimming pool is a large structure designed to hold a significant volume of water for recreational purposes. The capacity of a swimming pool is typically measured in gallons or liters, not pints.

Therefore, among the given options, the water bottle is the object that has a capacity best measured in pints.

The angle B in the triangle is 67.5 degrees.

The sum of angles in a triangle is 180 degrees. A triangle is a polygon that three sides.

Therefore, let's find the angle B in the triangle as follows:

Hence, let's find x

2x + 3x + 3x  = 180

8x = 180

divide both sides of the equation by 8

x = 180 / 8

x = 22.5

Therefore,

angle B = 3(22.5)

angle B = 67.5 degrees.

The metric system of measurement is based on the number 10.

This system is also known as the International System of Units (SI) and is used in most countries around the world. In the metric system, various units of measurement are defined as multiples or fractions of a base unit, which is defined for each quantity being measured. For example, the base unit for length is the meter, and the base unit for mass is the kilogram. Prefixes such as kilo-, centi-, and milli- are used to indicate multiples or fractions of the base unit, based on factors of 10. For example, a kilometer is 1000 meters, a centimeter is 1/100 of a meter, and a milligram is 1/1000 of a gram. This makes the metric system easy to use and convert between units, as well as consistent and universally recognized.

The simple interest would be $84.

What is simple interest?

Calculating the interest on a loan using simple interest is quick and simple. Simple interest is calculated by dividing the principle by the daily interest rate and the number of days between installments.

A quick and simple way to figure out interest on money is to use the simple interest technique, which adds interest at the same rate for each time cycle and always to the initial principal amount. Any bank where we deposit our funds will pay us interest on our investment. One of the different types of interest charged by banks is simple interest.

Interest = (Principle x Rate x Time in years)/100

            = (1200 x 3.5 x 2)/100

            = 84

The cubic function obtained from the parent function y=x³ after the given sequence of transformations is

y=-3(x + 1/2)³ + 3/4.

To determine the cubic function obtained from the parent function y=x³ after the given sequence of transformations, we will apply each transformation step by step:

1. Vertical stretch by a factor of 3:
The parent function y=x³ is stretched vertically by multiplying the y-values by 3. This transformation can be achieved by replacing y with 3y in the equation.
So, the equation becomes y=3x³.

2. Reflection across the y-axis:
The reflection across the y-axis is achieved by replacing x with -x in the equation.
So, the equation becomes y=3(-x)³.
Simplifying, we have y=-3x³.

3. Vertical translation 3/4 unit up:
The vertical translation 3/4 unit up is achieved by adding 3/4 to the y-values in the equation.
So, the equation becomes y=-3x³ + 3/4.

4. Horizontal translation 1/2 unit left:
The horizontal translation 1/2 unit left is achieved by adding 1/2 to the x-values in the equation.
So, the equation becomes y=-3(x + 1/2)³ + 3/4.

Total slack is simply the amount of time taken for a task to be delayed before the project finish date is delayed. It can be positive or negative.

It is calculated as the calculated as the value of the Late Finish minus the Early Finish field, and the Late Start minus the Early Start field.

Total slack = Late finish - early finish + late start - early start

Then we add the nominators

(2+5+6)/16 and we get 13/16

Answer:

Step-by-step explanation:

The next step is to change the denominators to the same number. The easiest for me will be 16. To change the denominators that don't already have 16. I will multiply  1/8 by 2 (both the numerator and dominator), and again will 3/8.

The probability of a player being between 5'8'' and 6'1'' is approximately 77%..

The given problem is an example of normal distribution because the height of players follows a normal distribution.Hence, if X represents the height of a player, then the distribution can be expressed as X ~ N(5′10″, 2)The problem requires the calculation of the probability that a player is between 5′ 8″ and 6′ 1″.Let z be the random variable that is the standard score corresponding to the player's height, given by:z = (x - μ)/σWhere x = 5'8'' = 5' + 8''/12 = 68'' and μ = 5'10'' = 5' + 10''/12 = 70'' and σ = 2''Therefore,z1 = (68 - 70)/2 = -1and z2 = (73 - 70)/2 = 1.5We can use the z-tables to find the area under the standard normal curve between -1 and 1.5 or we can use an online calculator for the normal distribution probability to find P(-1 ≤ z ≤ 1.5).Using an online calculator for the normal distribution probability, we get:P(-1 ≤ z ≤ 1.5) = P(z ≤ 1.5) - P(z ≤ -1) = 0.9332 - 0.1587 = 0.7745 or 77% (approximately)Therefore, the probability of a player being between 5'8'' and 6'1'' is approximately 77%.

200 sq cm

Step-by-step explanation:

Lateral surface area is the surface area without the bases, or without the top and bottom. So, you just add up the area of the 4 sides.

The front and back are both 10 x 20, so 200 each = 400

The left and right are 5 x 20, so 100 each = 200

The lateral surface area is 200 sq. cm.

The equation of the line shown in this problem is given as follows:

y = 2x.

The slope-intercept representation of a linear function is given by the equation shown as follows:

y = mx + b

The coefficients m and b have the meaning presented as follows:

The graph touches the y-axis at the origin, hence the intercept b is given as follows:

b = 0.

When x increases by one, y increases by 2, hence the slope m is given as follows:

m = 2.

Then the equation is:

y = 2x.

Length = 4 and one-fourths inches = 4.25 inches

Width = 18 and one-fourths inches = 18.25 inches

Height = 3 inches

V = 4.25 inches × 18.25 inches × 3 inches

V = 232.3125 cubic inches

To form a triangle, the set of line segments must satisfy the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Therefore, we need to check if the given line segments 8 cm, 4 cm, and 3 cm meet this requirement.

We can start by checking if the sum of the two smaller sides (3 cm and 4 cm) is greater than the largest side (8 cm). 3 cm + 4 cm = 7 cm, which is less than 8 cm. Therefore, these three line segments cannot form a triangle.

In general, for a set of line segments to form a triangle, the largest side must be smaller than the sum of the other two sides. In this case, the line segment of 8 cm is too long compared to the other two sides, which makes it impossible to form a triangle.

In conclusion, there are no line segments that meet the requirements to form a triangle with lengths of 8 cm, 4 cm, and 3 cm.
