The goalposts are 6.92m tall.

Angle of incidence Equals Angle of reflection, according to the physics principle of reflection.

Both angles  ( θ) are equal, as seen in the attached image.

m<ABC = mADC = 90° - θ

m<ACB = mECD = 90°

detailed explanation?

Angle of incidence Equals Angle of reflection, according to the physics principle of reflection.

Both angles  ( θ) are equal, as seen in the attached image.

m<ABC = mADC = 90° - θ

m<ACB = mECD = 90°

Thus, the ABC triangle and the EDC triangle will both be similar.

Their corresponding sides will also be proportionate due to the property of comparable triangles

AB/BD  =  CB/CD.

1.15/ED  =  2.0/12.5

ED  =   1.15  *   12.05 /2.0

ED=  6.92

ED = ED = 6.92 m

Each member of the club needs to pay £ 4.895 to cover the cost of hiring the buses.

A youth club's 143 members and eight leaders ride a bus to a bowling alley.

The buses for hire by the beezer bus company hold 32 passengers each.

The cost of each bus to hire is £140.

There are eight leaders and 143 members.

Therefore, there are a total of 143 + 8 = 151 passengers.

So, the number of buses required will be:

= 151 / 32 =  4.7 ≈ 5 buses

Therefore, the cost of hiring 5 buses will be:

= 5 × £140 = £ 700

As the eight leaders will not ay.

Therefore, the amount each member needs to pay is:

= £ 700 / 143

= £ 4.895

Each member of the club needs to pay £ 4.895 to cover the cost of the buses.

375π litters of water is needed to fill the cylindrical tank with a diameter of 1.0m and height of 1.5m.

A cylinder is simply a 3-dimensional shape having two parallel circular bases joined by a curved surface.

The volume of a cylinder is expressed as;

V = π × r² × h

Where r is radius of the circular base, h is height and π is constant pi.

Given the data in the question;

Plug the given values into the formula above and solve for V, to determine the liters of water that will fill the tank.

V = π × r² × h

V = π × ( 0.5m )² × 1.5m

V = π × 0.25m² × 1.5m

V = 0.375π m³

Next, convert cubic meters to liters.

V = 0.375π m³ = ( 1000 × 0.375π )L

Volume V = 375π L

Therefore, a volume of 375π litters is needed to fill the tank.

The probability that maximum speed differs from the mean value by at most 1.5 standard deviations is 0.1336.

The probability is typically defined as the proportion of positive outcomes to all outcomes in the sample space. It is written as, P(E) = (Number of favorable outcomes) = Probability of an Event (Sample space).

Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

The probability will be illustrated as:

P(|Z|>1.5)

= P(Z<-1.5) + P(Z>1.5)

= 2*P(Z<-1.5)

Look at the value under the distribution table. This is 0.0668.

Distance was 10 miles away from home.

What is Distance ?

The measurement of distance is the separation between two objects or points, and it can be quantitative or occasionally qualitative. Distance can refer to a physical length in physics or to an estimate based on other factors in ordinary language.
For a journey to see her cousin, Hannah traveled. She traveled 120 miles one way to visit her cousin and 120 miles the other way to return home.

She traveled halfway to her cousin's home in 1.2 hours.
That is 120 / 2 = 60 miles
(Speed = distance/time) 60 miles in 1.2 hours
Average speed = 60 / 1.2

                          = 50 mph.

For the remainder of the journey to her cousin's home, Hanna's average speed was 40 miles per hour.
Another 60 kilometers remain: Time (= Distance/Speed)
Time = 60/40

         = 1.5 hours.

Hanna averaged 55 miles per hour when she made her way home along the same path. Her automobile broke down after two hours.

Find the distance traveled at 55 mph in 2 hours. (Distance = time * speed)

Distance = 55 * 2 = 110miles

So distance from home will be,

= 120 - 110

= 10 miles

Hence, she was 10miles away from her home

The value of X and Y in the length of each side of an equilateral triangle is X = 3 and Y = 4

In this question we have been given the equations for the three sides of an equilateral triangle.

3X +12, 8X -3 and 5Y + 1

We need to find the value of X and Y.

We know that all sides of an equilateral triangle are equal.

so, 3X +12 = 8X -3 = 5Y + 1

Consider 3X +12 = 8X -3

3X -8X = - 3 - 12

-5X = - 15

X = 3

Now consider an equation 8X - 3 = 5Y + 1

substitute above value of X in this equation.

8(3) -3 = 5Y + 1

24 - 3 = 5Y + 1

21 - 1 = 5Y

5Y = 20

Y = 4

Therefore, the value of X and Y in the length of each side of an equilateral triangle is X = 3 and Y = 4

1. The algebraic expression that represents the amount left on her card after Laqueta buys 7 songs is 50 - 7s

2. The money that will be left on her card if each song costs $1.25 is $41.25.

From the information given, Laqueta has a $50 gift card for an online music store and each song costs s dollars.

In this case, the algebraic expression that represents the amount left on her card after Laqueta buys 7 songs will be:

= Total amount - Cost of songs

= 50 - (7 × s)

= 50 - 7s

where s = number of songs

The money that will be left on her card if each song costs $1.25 will be:

= 50 - 7s

= 50 - (7 × 1.25)

Mike's average score is 166.

Divide the total by the number of numbers after adding up all the numbers.

Implying something that sits in the midst. The average is the ratio created by dividing the total number of figures in a set by the total number of figures. Averages are used to condense a vast number of data points into a single value. It is a visual depiction of all the data set's available numbers. By adding up all the data values and dividing them by the total number of data points, the average is calculated.

Given Data

Mike bowled two games with scores of 157 and 175.

Sum of scores = 332

Average = [tex]\frac{Sum of scores}{Totak number of bowling}[/tex]

Average = [tex]\frac{157 + 175}{2}[/tex]

Average = [tex]\frac{332}{2}[/tex]

The area under a curve in calculus is a picture of an integral. It is frequently possible to interpret the area under a curve as the total amount of whatever the function is describing.

By performing a definite integral between the two locations, one can determine the area under a curve between two points. Integrate y = f(x) between the limits of a and b to tell about the area under the curve y = f(x) between x = a & x = b.
