Answer:

260 centimeters is more

Step-by-step explanation:

There is 100 cm in 1 meter, which means that there would be 250 cm in 2.5 meters. 250 < 260, so 260 cm is greater than 2.5 meters.

The value of the height(h) is  10. 0702 cm

From the information given, we have to use the SOHCAHTOA rule

Using the trigonometric identities, we have;

From the diagram shown, we have;

Using the trigonometric identity, sine, we have;

sine 46 = h/ 14

Now, cross multiply, we get;

h = sin 46 × 14

find the value and substitute

h = 0. 7193 × 14

h = 10. 0702 cm

Hence, the value is 10. 0702 cm

The sequence of height of the ball after each bounce are in geometric sequence with ratio of 0.75.

What is Arithmetic Progression ?

Arithmetic progression can be defined as the sequence of numbers which has same difference between any consecutive numbers.

Given,

A ball is dropped from the height 160cm

And the ball loses 25% of its previous height after each bounce.

so,

for every bounce the height will be decreased by 25%

after first bounce , 160 - 160/4 = 120

after second bounce , 120 - 120/4 = 90

after third bounce , 90 - 90/4 = 67.5

The sequence could be 160,120,90,67.5 and soon

if a1 / a2 = a2/a3

it is said to be in gp

so a1/a2 = 120/160 = 0.75

a2/a3 = 90 / 120 = 0.75

Hence , we can say that the sequence is in gp with common ratio of 0.75

The variable x has infinite many solutions in the expression 10x - 3 + 2x + 4

From the question, we have the following parameters that can be used in our computation:

10x - 3 + 2x + 4

The given parameter above is an expression, not an equation

This means that we cannot determine the value of x

This is so because the variable x has infinite many solutions

The new temperature in Moscow is +2 °C. (b) The temperature in Juneau falls by 6 °C.

Temperature in mathematics is usually referred to as a measure of the average kinetic energy of the particles in a system. The higher the temperature of the system, the more energetic the particles are and the more likely they are to move around. Temperature is usually measured in Kelvin, Celsius, Fahrenheit, or Rankine.

The new temperature in Moscow is now +2 °C.
The temperature falls by 6 degrees Celsius from 4°C to -2°C. This drop in temperature is an example of how quickly the weather can change in Juneau. The city is located in Southeast Alaska, along the coast of the Gulf of Alaska. This means that it is often subject to sudden shifts in temperature and weather patterns due to its close proximity to the ocean. The high humidity and large temperature range make Juneau a great place for outdoor activities like kayaking, fishing and hiking. However, it's important to always be prepared for changes in the weather.

The probability of rolling a 3 on a fair 6-sided die that P(3) is 0.17.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

Since each side of the die is equally likely to land face up,

So the number of favorable outcomes n(E) = 1

And the total number of outcomes n(S) = 6

Thus, P(3) is the probability of rolling a 3 on a fair 6-sided die :

P(3) = n(E)/n(S)

P(3) = 1/6

A two-dimensional shape having seven sides and seven angles are called a heptagon. It is a member of the two-dimensional geometry polygon class. Polygons are closed geometric shapes with only straight edges. In Greek, "hepta" denotes seven, while "gonia" denotes an angle.

The true statements about the reflectional symmetry of a regular heptagon are:

A line of symmetry will connect a vertex and a mid-point of an opposite side,

A regular heptagon has 7 sides. So, it has 7-fold symmetry

21/8 = 2 5/8

Therefore, Tom took 2 and 5/8 hours to clean the two rooms

Answer: 2 5/8 hours ( 2 hours and 38 mins [rounded])

Step-by-step explanation: For the best experience, look at the attachment:

So, first I took the numbers and set up an addition problem. But we have a problem. They both don't have the same denominator. So first, we need to find a common denominator before we add. So, luckily we know that 2 is a factor of 8. So 1/8 would stay the same and we'd multiply the 2 by 4 to get the denominator, and 1 by 4 to get the denominator. Then, you'd add 2 1/8 to 4/8 to get 2 5/8. Also, I converted 5/8 of an hour to get 37.5 mins, so I rounded up to 2 hrs and 38 mins.

Using the slope-intercept general form of y = mx + c , Parallel lines have same slope and (0,2) gives c = 2 , The answer is y=3x/4 + 2.

An equation is a statement of equality between two expressions. It typically includes numbers and mathematical operations such as addition, subtraction, multiplication, and division. For example, the equation 2x + 3 = 7 is a statement that the value of the expression 2x + 3 is equal to the value of 7. Equations can also include variables, which represent unknown values that can be solved for.

In a linear equation, the slope (also called the gradient) is a measure of the steepness of the line, and the y-intercept is the point at which the line crosses the y-axis. The slope of a linear equation can be represented as m in the form of y = mx + b, where m is the coefficient of x, and b is y-intercept. The y-intercept is the point where the line crosses the y-axis, which can be represented by the value of b in the form of y = mx + b.

Yes, it is possible for an object to have zero momentum. Momentum is defined as function the product of mass and velocity, so an object with zero mass or zero velocity will have zero momentum.

Momentum is a physical property of an object that is equal to the product of its mass and velocity. It is measured in kilogram meters per second (kg m/s) and is a vector quantity, meaning it has both magnitude and direction. In order for an object to have zero momentum, it must have either zero mass or zero velocity. An object with zero mass will always have zero momentum regardless of its velocity, while an object with zero velocity will only have zero momentum if its mass is also zero. An object with nonzero mass but zero velocity still has nonzero momentum if its mass is not zero. Therefore, it is possible for an object to have zero momentum.
