Answer:

£8.10

Step-by-step explanation:

Since we have to convert Euro to pound we will first find value of one euro in terms of pound.

Given

£3 = €4

=> £3/4 = €1

=> €10.80 = £3/4 * 10.80  ---->multiplying both side by 10.80 as we have have to find value of €10.80  in pounds

= > €10.80 = £8.10

Answer:

£8.10

Step-by-step explanation:

Given,

£3 = €4

Dividing both side by four

€1 = £0.75

We have to convert €10.80 to pounds

Multiplying 10.80 both side

€10.80 = £0.75 x 10.80

€10.80 =£8.10

Hence,  €10.80 is equal to £8.10.

Answer:

The probability is 1/254,251,200

Step-by-step explanation:

We proceed as follows;

Firstly, we are selecting 5 state capitals out of 50. The number of ways we can do this is 50P5 = 50!/5!(50-5)! = 254,251,200 ways

Now, out of this number of ways , only one route is desired in that particular order.

This means the probability of having the route scheduled in that particular order would be;

1/254,251,200

Answer:

0.000000003933

Step-by-step explanation:

As the candidate will visit the capitals of 5 of the 50 states, the probability of each capital being selected is 1/50.

As we want a probability of 5 specific capitals in a specific order, we can calculate the probability of each capital being chosed:

First city being Sacramento: Probability of 1/50

Second city being Albany: Probability of 1/49 (as the first city is not available now)

Third city being Juneau: Probability of 1/48

Fourth city being Hartford: Probability of 1/47

Fifth city being Bismarck: Probability of 1/46

So the final probability is 1/(50*49*48*47*46) = 0.000000003933

Answer:

18.75 meters

Step-by-step explanation:

Final answer:

To find 15 meters increased by 25%, multiply 15 by 0.25 to get 3.75 meters, then add this to the original length to obtain 18.75 meters.

Explanation:

To calculate a 15 meters increase by 25%, first determine what 25% of 15 meters is. You do this by multiplying 15 by the percentage in decimal form (25% = 0.25), so: 15 meters * 0.25 = 3.75 meters. Then, to find the new length, you add this to the original 15 meters to get the total.

15 meters + 3.75 meters = 18.75 meters. Therefore, 15 meters increased by 25% is 18.75 meters.

Step-by-step explanation:

Convert the percentage increase to a decimal: 25% → 0.25.

Multiply the original length by this decimal: 15 meters * 0.25 = 3.75 meters.

Add the increase to the original length: 15 meters + 3.75 meters = 18.75 meters.

Final answer:

The submarine will travel approximately 1532 feet horizontally as it dives down at an angle of depression of 40 degrees to a depth of 2000 feet, using the cosine trigonometric function to calculate this distance.

Explanation:

The student's question involves finding the horizontal distance a submarine will travel as it dives at a given angle of depression. When solving problems like this, we can use trigonometric functions, specifically the cosine function, because the horizontal distance is the adjacent side of a right-angled triangle, with the angle of depression being one of the angles, and the depth of the dive being the opposite side.

Now calculate the horizontal distance: x = 2000 * 0.766, which gives us x ≈ 1532 feet.

Therefore, the horizontal distance traveled by the submarine when it finished its dive is approximately 1532 feet.

Answer:

76.3 millions of people per year

Step-by-step explanation:

Missing text of the question:

"The world population1 , in billions, was approximately

[tex]P=7.17e^{0.01064t}[/tex]

where t is in years since April 20, 2014. At what rate was the world's population increasing on that date? Give your answer in millions of people per year, rounded to one decimal place."

Answer:

The expression that gives us the world population in billions t years after April 20, 2014 is

[tex]P=7.17e^{0.01064t}[/tex]

Where t is expressed in years.

Here we want to find the rate of change of this function at that date.

The rate of change of a function is given by its derivative. Therefore, we have to calculate the derivative of the function P, and the calculate its value at the date indicated.

The derivative of the function is:

[tex]P'(t)=7.17 \cdot 0.01064 e^{0.01064 t}=0.0763 e^{0.01064t}[/tex]

Now we want to find the rate of change at the date April 20, 2014, which means zero years after that date; so we have to substitute t = 0 into the expression of the derivative, and we find:

[tex]P'(0)=0.0763e^0 = 0.0763[/tex]

So, 0.0763 billions, which corresponds to 76.3 millions of people per year.

Step-by-step explanation:

The total number of guests for lodge to be full = 153

During heavy snow fall, the lodge will be full.

The expected number of guests during heavy snow fall = 153

During partial snow fall, the expected number of guests = 62

The probability of heavy snowfall = 0.4

The probability of partial snow fall = 1 - 0.4 = 0.6

The expected number of guests = [(0.4) (153)] + [(0.6) (62)]

= 61.2 + 37.2

Answer: 18°

Step-by-step explanation:

From the question, Miles hs a piece of paper that is 1/4 of a large circle and he cuts the paper into five equal parts from the center of the circle.

The total angle of a circle is 360°. Since Miles caught 1/4 of the circle, this means that he'll have an angle of : 360° × 1/4 = 90°.

Then, he now cuts the paper into five equal parts. This means that we divide 90° by 5 which will give:

= 90° ÷ 5

= 18°

The angle measure of each part is 18°.

Answer:

18°

Step-by-step explanation:

Extracting the key information from the question:

*** Miles has paper that is 1/4 of a large circle.

*** He cut this paper into five equal parts.

*** We are required to calculate the angle measure of each part.

The sum of the angles in a circle is 360°. So I miles has 1/4 of a large circle, it means that the sum of the angles of this paper should be a quarter of 360°

= 1/4 × 360°

= 90°

Again, since he cuts the paper into five equal parts, we will find the angle measure of each part by dividing 90° by 5.

The angle measure of each

= 1/5 × 90°

= 18°

Therefore, each of the five parts of paper had an angle of 18°

Given:

Given that the triangular prism with height 10 inches.

The side lengths of the base of the triangle are 12 inches, 13 inches and 5 inches.

We need to determine the surface area of the prism.

Surface area of the prism:

The surface area of the prism can be determined using the formula,

[tex]SA=bh+(s_1+s_2+s_3)H[/tex]

where b is the base and h is the height of the triangle.

s₁, s₂, s₃ are the side lengths of the triangle and

H is the height of the prism.

Substituting b = 12, h = 5, s₁ = 12, s₂ = 5, s₃ = 13 and H = 10 in the above formula, we get;

[tex]SA=(12)(5)+(12+5+13)(10)[/tex]

[tex]SA=60+(30)(10)[/tex]

[tex]SA=60+300[/tex]

[tex]SA=360 \ in^2[/tex]

Thus, the surface area of the triangular prism is 360 square inches.

Hence, Option b is the correct answer.

Answer: BC = 15

Step-by-step explanation:

Since the triangles are congruent, that means they are the same. So side AB = side EF. Since we know side FD is 15, that means side BC= 15

Final answer:

To find BC when given triangles ABC and DEF are congruent and the perimeter of DEF is 38, subtract the summed lengths of DE and EF from 38 to get the length of DF, which will be equal to BC.

Explanation:

If you are given that triangle ABC is congruent to triangle DEF and the perimeter of DEF is 38 units, to find the length of side BC, we need to first establish that corresponding sides of congruent triangles are equal in length. This means that each side of triangle ABC corresponds and is equal to a side of triangle DEF. Therefore, if you are given the lengths of sides DE and EF, you subtract their sum from the total perimeter of triangle DEF to find the length of side DF. Since triangle ABC is congruent to triangle DEF, BC is equal to DF. Thus, the length of side BC in triangle ABC can be calculated.

For example, if DE is 10 units and EF is 12 units, then:

The coordinate of S' is (1, -5) if the triangle in the diagram is translated 3 units right and 4 units down.

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

Let point is (-2, -1)

Now,

Translated 3 units right, the x-coordinate of the point = -2 + 3 = 1

Translated 4 units down, the y-coordinate of the point = -1 - 4 = -5

The coordinate of S' is (1, -5)

Thus, the coordinate of S' is (1, -5) if the triangle in the diagram is translated 3 units right and 4 units down.

log Subscript 2 Baseline 9 x cubed is equivalent to 2 log subscript 2 Baseline 3 + 3 log subscript 2 Baseline x

Step-by-step explanation:

Given:

log Subscript 2 Baseline 9 x cubed?

Required:

Find the equivalent of the above expression.

First, we need to represent it mathematically;

log Subscript 2 Baseline 9 x cubed = [tex]log_{2} 9x^{3}[/tex]

From Laws of logarithm  

[tex]log_{x} AB = log_{x} (A* B)\\log_{x} AB = log_{x}A + log_{x}B[/tex]

Note how the expression is split into two

We'll apply the same logic above, here

First, is to simplify the mathematical expression;

[tex]log_{2} 9x^{3} = log_{2} (9 * x^{3})[/tex]

Then we split into two

[tex]log_{2} 9x^{3} = log_{2}(9) + log_{2}(x^{3})[/tex]

[tex]log_{2} 9x^{3} = log_{2}(3^2) + log_{2}(x^{3})[/tex]

Also from laws of logarithm,

[tex]log_{m}A^{n} = nlog_{m}A[/tex]

We'll apply this law on [tex]log_{2}(x^{3})[/tex] and [tex]log_{2}(3^{2})[/tex]

[tex]log_{2}x^{3} = 3log_{2}x[/tex]

[tex]log_{2}(3^2) = 2log_{2}3[/tex]

So, [tex]log_{2} 9x^{3} = log_{2}(9) + log_{2}(x^{3})[/tex] becomes

[tex]log_{2} 9x^{3} = 2log_{2}3 + 3log_{2}x[/tex]

log Subscript 2 Baseline 9 x cubed is equivalent to [tex]2log_{2}3 + 3log_{2}x[/tex]

[tex]2log_{2}3[/tex] can be represented as 2 log subscript 2 Baseline 3

and

[tex]3log_{2}x[/tex] can be represented as 3 log subscript 2 Baseline x

Hence, log Subscript 2 Baseline 9 x cubed is equivalent to 2 log subscript 2 Baseline 3 + 3 log subscript 2 Baseline x

The probability of drawing a red marble first and a yellow marble second is 5/21.

To find the probability that the first marble drawn is red and the second one is yellow, we need to consider the total number of marbles and the number of red and yellow marbles in the bag.

Since we are drawing without replacement, the probabilities are dependent.

The probability of drawing a red marble on the first draw is 5/7. After the first marble is drawn, there are now 4 red marbles and 2 yellow marbles left in the bag. The probability of drawing a yellow marble on the second draw is 2/6.

Therefore, the probability of drawing a red marble first and a yellow marble second is (5/7) × (2/6) = 10/42 = 5/21.

Final answer:

The probability of drawing a red marble first and then a yellow marble from a bag with 2 yellow marbles and 5 red marbles is calculated by multiplying the probability of each event, giving a final answer of 5/21.

Explanation:

The calculation of the probability that the first marble is red and the second one is yellow when two marbles are drawn without replacement from a bag containing 2 yellow marbles and 5 red marbles involves step-by-step conditional probabilities.

Step 1: Calculate the probability of drawing a red marble first. Since there are 5 red marbles out of a total of 7 marbles, the probability is 5/7.

Step 2: Now that a red marble has been drawn and not replaced, there are 1 yellow marble less and 1 red marble less in the bag, making a total of 6 marbles. The probability of then drawing a yellow marble is 2/6, or 1/3.

Step 3: To find the combined probability of both events happening in sequence (a red marble first, then a yellow marble), multiply the individual probabilities: (5/7) * (1/3).

The final answer is therefore (5/7) * (1/3) = 5/21.

The angles are 150°, 108°, 90°, and 12°.

In a literal sense, corresponding means pairwise angles. Like the right corner angles of two triangles etc. But usually, we take them as:

For two similar figures, the pair by pair similar angles of those two similar figures are called corresponding angles. They are of the same measurement.

Suppose for example, that 10 people choose city A as a destination.

To calculate its corresponding angle, we have to use the following proportion, 60 people represent the whole circle, is 360°, then 10 people are represented by:

France:

25/60 × 360 = 150°

Spain:

18/60 × 360 = 108°

Greece:

Final answer:

x = -3 ±√24.

Explanation:

To solve the quadratic equation x²+6x-15=0 by completing the square, follow these steps:

First, move the constant term to the other side of the equation:

x² + 6x = 15.

Add the square of half the coefficient of x to both sides to complete the square: (6/2)² = 9, so add 9 to both sides resulting in x² + 6x + 9 = 24.

Now the equation is a perfect square on the left side:

(x+3)² = 24.

Take the square root of both sides to solve for x:

x+3 = ±√24.

Subtract 3 from both sides to find the values of x:

x = -3 ±√24.

Answer:

Step-by-step explanation:

In order to find the side lengths, you can either draw it out, or imagine it in your head. I would recommend drawing it if you're unfamiliar to the topic.

So when you draw it out, you see that AB is the width of the rectangle, and BC is the length.

In order to calculate it, you'd have to keep in mind which direction each line goes. Since AB is horizontal, we would use the x coordinates to find the length. [tex]x_{1}[/tex]-[tex]x_{2}[/tex] is the formula, where A is [tex]x_{2}[/tex], since it is farther left.

width = 2 - (-3)

w = 5

Now, you'd do the same thing, but with BC, and [tex]y_{1}[/tex]-[tex]y_{2}[/tex]. In this case, B is [tex]y_{1}[/tex], since it is further up.

length = 2 - (-4)

l = 6

Now, multiply them to find the area of a rectangle.

Answer: A = $1503.6

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1 + r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

P = 1000

r = 6% = 6/100 = 0.06

n = 1 because it was compounded once in a year.

t = 7 years

Therefore,.

A = 1000(1 + 0.06/1)^1 × 7

A = 1000(1.06)^7

A = $1503.6
