All four of these numbers are rational.

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.

Answer: x = 70

Step-by-step explanation: the sum of the angle 2x-5  and 45 deg should equal 180 deg, so 2x-5 should be equal to 135 because 180 - 45 = 135

So 2x -5 = 135. Add 5 to both sides to cancel it out. 2x = 140. divide both sides by 2 to cancel 2 on x. Answer is X=70

The change in area is 0.8π [tex]m^{2}[/tex] and percentage is 20%.

What is change in area?

Let A denotes the area of the circle when its radius is r, then A=πr2 Now, the rate of change of the area with respect to its radius is given by, dA dr = d dr(πr2) = 2πr When r= 4cm,(dA dr)r=4= 2π(4) = 8π cm2 per cm Hence, the area of the circle is changing at the rate of 8πcm2/cm

Given,

initial radius = 2m

increased radius = 2.02 m

change in radius dr = 2.02 - 2 = 0.02m

Area = π[tex]r^{2}[/tex] = 4π

dA = 2πrdr

=2π(2)(0.02)

=0.08π [tex]m^{2}[/tex]

Estimated percentage = 0.08/4×100

=2%

Hence, the estimated percentage is 2%.

Answer:

7776

Step-by-step explanation:

you divide 5 by 2 to get 2.5 then put 36 to the power of 2.5 to get 7,776

The remainder when [tex]5^{400}[/tex] is divided by 19, the remainder is 17.

Remainder

The Remainder is the value left after the division. If a number (dividend) is not completely divisible by another number (divisor) then we are left with a value once the division is done. This value is called the remainder.

We can write,

[tex]5^{400} = (5^4)^{100} = 625^{100}[/tex]

We know that,

19*33 = 627

Hence, we can write 625 as 627 - 2

It will become,

[tex]\frac{(627-2)^{100}}{19}=\frac{(-2)^{100}}{19}[/tex]

We know that, even power of any number and its negative counterpart will be same.

Hence, we can write,

[tex]\frac{(-2)^{100}}{19}=\frac{(2)^{100}}{19} = \frac{2*2^{99}}{19}[/tex]

We know that 99 = 11*9

Hence, we can write,

[tex]\frac{2*({2^9})^{11}}{19} =\frac{2*512^{11}}{19}[/tex]

We know that,

19*27 = 513

Hence, we can write, 512 as 513 - 1

[tex]\frac{2*(513-1)^{11}}{19}=\frac{2(-1)^{11}}{19}[/tex]

2*(-1)/19 = -2/19

It means the remainder will be 19 - 2 = 17.

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

There is a 70.6% chance that none of the 4 randomly picked people share your zodiac sign.

Probability is a branch of mathematics in which we determine how likely an event is to happen. It is used when we are not sure about the result or outcome of an event so we consider the probabilities of certain outcomes.

In this case, there are 12 zodiac signs, out of which one is yours. So the probability or chance that the 4 randomly picked people do not share your zodiac sign can be determined as follows;

Probability of one person not having your zodiac sign: 11/12

Probability of 4 people not having your zodiac sign;

11/12 × 11/12 × 11/12 × 11/12 = 0.706

Converting it into percentage:

0.706 × 100 = 70.6%

As per the tangent angle, the value of x in the given diagram is 7cm.

Tangent angle

The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.

Given:

Here we have the two right angled triangle, through this we have to identify the value of x.

According to the given question, we have a diagram with two right angled triangles.

Now, in the upper right angled triangle

tan 50° = opposite side / 5

⇒ 1.19 = 0pposite side/ 5

⇒ opposite side = 1.19 × 5

⇒ opposite side = 1.2 × 5

⇒ opposite side = 6cm

Now, the opposite side with respect to the angle 50  degrees in the upper right angle triangle is a adjacent side according to angle 38 degrees in the lower right angle triangle.

So, in the lower right angle triangle.

tan 38° = x / adjacent side

⇒ 0.78 =  x/6

⇒ x = 0.78 × 6

⇒ x = 4.68

⇒ x = 7cm

A computer base unit of mass 4.5 kg is dragged along smooth desk, if tension in each arm of the person dragging it is 16 N and acts at 22° above the horizontal, then what is the normal reaction force is 32.12N.

A force is effect that can alter an object's motion according to physics. A force can cause an object with mass to accelerate when it changes its velocity, for as when it moves away from the rest. An obvious way to describe force is as push or a pull. A force is vector quantity since it has both magnitude and direction. It is calculated by using newton SI unit (N). Force is denoted by letter F. (formerly P).

The net force acting on object is equal to the rate at which its momentum varies over time, according to Newton's second law in its original formulation. This law suggests that object's acceleration is directly proportional to the net force acting on it, is in the direction of the net force, and is inversely proportional to mass of the object if the object's mass is constant.

a) The expected value is calculated to be 2.273 and b) the standard deviation is 1.499 if a random sample of 200 children is selected.

According to the report 1 in 88 American children has been diagnosed with ASD, therefore the probability can be given as;

p = 1 / 88

a) the expected value can be calculated as follows;

E (X) = n × p

here n = sample size = 200

p = probability = 1 / 88

E (X) = 200 × 1 / 88

E (X) = 2.273

b) To find the standard deviation, first, we have to determine the variance of the random variable;

V (X) = n × q × p

V (X) = 200 × 87/88 × 1/88

V (X) = 2.2468 = 2.247

Now we can calculate the standard deviation as follows;

standard deviation = √V(X)

standard deviation = √2.247

standard deviation = 1.499

Therefore, the expected value and standard deviation are calculated to be 2.273 and 1.499 respectively.

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
