Answer:

I think that you would divide all the euros by 1.35 to get the pounds

if thats right then the answer should be £2504.07407408

Step-by-step explanation:

i did this by first getting the hotel price (125 euros per night) and timesing that by 14 as they stay for 14 nights, this gives you 1750

then i converted 1750 to pounds by dividing 1750 by 1.35 to get £1296.2962963

next i did the wifi price (6 x 13 = 78, 78 divided by 1.35 = £57.7777777778)

after that i added those two prices together to get £1354.07407408

the final step was to add £1150 so i got £2504.07407408, and that hopefully should be the answer !

hope this works :)

The graphical solution for a system of two equations is found at the intersection of the two lines. At point (1, 4) line B intersect line D, therefore this point is the solution of the set of equations B and D.

Answer:

Gold weighs more

Step-by-step explanation:

The fact that they both equal 16 oz confirms the fact that gold weighs more. The reason for this is because even if the mass is the same the weight involves the gravitational pull on the earth meaning gold is greater.

1 pound of gold weighs more than 16 ounces of Soda.

We are told that;

Weight of soda = 16 Oz (ounces)

Weight of gold = 1 pound

Now, from conversions between pounds and ounces, 1 pound = 16 oz

Thus means that soda too also has a mass of 1 pound same as Gold.

However, despite the fact that they have the same mass, it doesn't mean they weigh the same because Gold has a gravitational pull which means force of gravity on it from the earth and it means it will weigh more.

Answer:

6 minutes more

Step-by-step explanation:

Time = Distance ÷ Speed

Time = 30miles ÷ 60mph

Time = 30mins

Time = 30miles ÷ 50mph

Time = 36mins

36mins - 30mins = 6mins difference

Answer: 6 minutes

Step-by-step explanation:

Time = Distance / speed

When speed is 60 mph

Time = 30/60 = 1/2 hour = 30 minutes

When speed is 50 mph

Time = 30/50 = 3/5 hour = 36 minutes

Answer:

£170000

Step-by-step explanation:

In 2010, Rafik bought a house. Let us assume Rafik bought the house for $x.  In 2015, Rafik sold the house to Bianca and made 20% profit. 20% profit = 20% of x = 0.2 × x = 0.2x. Therefore Rafik sold the house to Bianca at x + 0.2x = 1.2x. Bianca bought the house at 1.2x

The house was sold by Bianca at 5% loss in 2019. 5% loss = 0.05(1.2x) = 0.06x

Therefore the house was sold by Bianca at 1.2x - 0.06x = 1.14x. Since Bianca sold the house at £193800.

⇒ 1.14x = 193800

x = 193800/1.14

x = £170000

Rafik paid £170000 for the house in 2010

Answer:

x = 4

Step-by-step explanation:

It is stated that f(x) passes through

(-3, 3), (0, 3), (4, 3)

and g(x) passes through

(-4, -3), (0, 0), (4, 3)

Therefore, both functions pass through (4, 3). That is, the input value x = 4 produces the same output value y = 3 for the two functions.

Answer:

The additive inverse of the polynomial  being subtracted is -0.612-8+181

Step-by-step explanation:

Given expression : (1.32 +0.412 – 241) – (0.612 + 8 - 181)

Now the polynomial being subtracted : (0.612 + 8 - 181)

Additive inverse : The number in the set of real numbers that when added to a given number will give zero.

So, Additive inverse of 0.612 = -0.612

Additive inverse of 8 = -8

Additive inverse of -181 = 181

So, The additive inverse of polynomial being subtracted : -0.612-8+181

So, Option B is true

Hence the additive inverse of the polynomial  being subtracted is -0.612-8+181

Standard deviation  for the number of people with the genetic mutation = 4.178

Step-by-step explanation:

Explanation:-

Given random sample size 'n' =600

proportion of the Population 'p'=3% or  0.03

Let 'X' be the random variable in binomial distribution

Mean of the  binomial distribution

                              μ = n p

                                 = 600 X 0.03

Answer:

Step-by-step explanation:

If you were to complete 4 out of the 24 current homework problems, then I can say that you'd have 5/6 of the problems remaining. This is because 24 divided by 4 is 6, so completing 4 questions counts as completing 1/5 of the total amount of work present. If you want to use whole numbers instead of fractions, you would have completed 4 out of 24 questions and would have 20 remaining

Answer:

y= -2/5 and y=1

Step-by-step explanation:

Start by transforming the equation to your liking:

[tex]5y^2-2=3y\\5y^2-3y-2=0\\[/tex]

Now we have to factor! To do this we have to find common numbers. Do this by multiplying -2 and 5 to get -10. Now think about which two numbers add multiply to be -10 but also add up to be -3 (I got this number from the middle of the equation). The two numbers you should've got are -5 and 2.

Now substitute those two number in place of the middle term, which is -3y like so:

[tex]5y^2-5y+2y-2 =0[/tex]

Now solve the equation in pieces... find the greatest common factor from [tex](5y^2-5y)[/tex] and the greatest common factor from [tex](2y-2)[/tex] . The two common factors for both of those are 5y and 2. Your equation should now look like this:

[tex]5y(y-1)[/tex] + [tex]2(y-1)[/tex]

The two greatest common factors become into one group and the other equation that they have in common (y-1) is it's own equation:

[tex](5y+2)(y-1)=0[/tex]

Now equal both of the equations to 0 and solve for y to get both of the values of y.

Answer:

1.34 feet/seconds

Step-by-step explanation:

Looking at the above question, we would be converting 55 miles per hour to feet per seconds.

From the above question, we are given the following conversion values

1 minute = 3,600 seconds

1 mile = 5,280 feet

55 miles per hour = 55 mile / 1 hour

So,

If 1 mile = 5,280 feet

55 miles = x feet

We cross Multiply

x = 5,280 × 55

x = 290,400 feet

Hence, 55 miles = 290,400 feet

1 hour = 60 minutes

If 1 minute = 3,600 seconds

60 minutes = x seconds

We cross multiply

x = 60 × 3,600

x = 216,000 seconds.

This means

60 minutes = 216,000 seconds

In other to find out how fast is the car is,

Speed = Distance / Time

Speed = 290,400 feet/216,000 seconds

Speed = 1.3444444444 feet/seconds

To the to the correct number of significant figures, the car is traveling at 1.34 feet per second.

Answer:

(1)155 degrees

(2)135 degrees

(3)105 degrees

Step-by-step explanation:

Let the original angle [tex]= \theta[/tex]

Angle Bisector of the original angle = [tex]\dfrac{ \theta}{2}[/tex]

If the other angle forms a linear pair, then:

The other angle, [tex]\beta=180^\circ-\theta[/tex]

Therefore, the measure of the angle formed by the angle bisector of the original angle and the opposite ray is:

[tex]\dfrac{ \theta}{2}+180^\circ-\theta\\=180^\circ-\dfrac{ \theta}{2}[/tex]

(1)If the angle equals 50°

Then the measurement of the required angle

[tex]=180^\circ-\dfrac{ 50}{2}\\=180^\circ-25^\circ\\=155^\circ[/tex]

(2)If the angle equals 90°

Then the measurement of the required angle

[tex]=180^\circ-\dfrac{ 90}{2}\\=180^\circ-45^\circ\\=135^\circ[/tex]

{3)If the angle equals 150°

Then the measurement of the required angle

[tex]=180^\circ-\dfrac{ 150}{2}\\=180^\circ-75^\circ\\=105^\circ[/tex]

- 11 + (47)(-3) = -152

Answer:

d

Step-by-step explanation:

Let m = number of miles.

Each mile costs $2.35, so m miles cost 2.35m.

The flat fee is $2.

The total cost is

2.35m + 2

He can spend no more than $47, so he can spend $47 or less,

2.35m + 2 <= 47

Answer: d

Answer:

y = 49

Step-by-step explanation:

y ∝ x²

=> y = kx²

Where k is the constant of proportionality

k = 1 (We've found this out in the previous question)

Now,

y = ? when x = 7

The above equation becomes:

=> y = (1)(7)²

=> y = (1)(49)

=> y = 49
