1 euro=85p
4.5 litres=1 gallon
sam thinks petrol is cheaper in spain than wales.
Work out if sam in correct?

Answers

The amount for 1 Liter of petrol in Wales is less than the amount for 1 Liter of Petrol in Spain

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the amount of petrol in Spain be = A

Let the amount of petrol in Wales be = B

Now , the total amount Sam paid for 18 Liters of petrol in Spain = 27 euros

1 euro = 0.85 pounds

So ,

Total amount Sam paid for 18 Liters of petrol in Spain = 27 x 0.85 pounds

Total amount Sam paid for 18 Liters of petrol in Spain = 22.95 pounds

So ,

The amount for 1 Liter of petrol in Spain = Total amount Sam paid for 18 Liters of petrol in Spain / 18

Substituting the values in the equation , we get

The amount for 1 Liter of petrol in Spain = 22.95 / 18

The amount for 1 Liter of petrol in Spain = £ 1.275

And ,

Now , the total amount Sam paid for 8 gallons of petrol in Wales = £ 40.80

1 gallon = 4.5 Liters

8 gallons = 4.5 x 8 Liters

8 gallons = 36 Liters

So ,

Total amount Sam paid for 36 Liters of petrol in Wales = £ 40.80

So ,

The amount for 1 Liter of petrol in Wales = Total amount Sam paid for 36 Liters of petrol in Spain / 36

Substituting the values in the equation , we get

The amount for 1 Liter of petrol in Wales = 40.80 / 36

The amount for 1 Liter of petrol in Wales = £ 1.13

£ 1.13  <   £ 1.275

Therefore , the amount for 1 Liter of petrol in Wales is less than the amount for 1 Liter of Petrol in Spain

Hence , The amount for 1 Liter of petrol in Wales is less than the amount for 1 Liter of Petrol in Spain

A square is inscribed in a circle. Write the area of the square as a function of the radius.

Answers

Area will be 2[tex]r^{2}[/tex]

What is area?

Area is the entire amount of space occupied by a flat (2-D) surface or an object's form.

Given radius of circle is r

Then area of circle=π[tex]r^{2}[/tex]

The diagonal of the square is comparable to the diameter (2r) of the circle since two opposing corners of the square contact it.

Now, we will set up Pythagoras' Theorem to determine one side of the square:

[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]

Since it is a square a=b which means all  the sides are same

∴2[tex]a^{2}[/tex] = [tex]c^{2}[/tex]

We know c, which is 2r, the diagonal.

∴2[tex]a^{2}[/tex] = [tex](2r)^{2}[/tex]

⇒[tex]a^{2}[/tex] = 2[tex]r^{2}[/tex]

We can leave it as [tex]a^{2}[/tex]

since a is one side of the square and [tex]a^{2}[/tex] would be the area of the square.

So the area of the square =2[tex]r^{2}[/tex]

In the equation 0.20 would be the value increasing and 1.50 the initial value.

At a real estate​ agency, an agent sold a house for ​$374,000. The commission rate is ​4.5% for the real estate agency and the commission rate for the agent is ​25% of the amount the real estate agency gets. How much did the agency make on the​ house? How much did the agent earn in​ commission?

Answers

The amount agency makes on the house is $16830 and the agent got $4207.5 based on the given rate or percentage.

What is the percentage?

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

Total cost of house = $374,000

The commission rate of real estate = 4.5%

4.5% of $374,000 = (4.5/100)374000 = $16830

The commission rate of agent = 25 % of $16830

(25/100)16830 = $4207.5

Hence "The amount agency makes on the house is $16830 and the agent got $4207.5 based on the given rate or percentage".

How to solve inequality?

In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

In other words, Inequalities are mathematical expressions involving the symbols >, <, ≥ and ≤.

Therefore, let's solve the inequality for the lowest integer value of m

7m + 5 > 49 - 3m

add 3m to both sides of the inequality

7m + 5 > 49 - 3m

7m + 3m + 5 > 49 - 3m + 3m

10m + 5 > 49

subtract 5 from both sides of the inequality

10m + 5 > 49

10m + 5 - 5 > 49 - 5

10m > 44

m > 44 / 10

m > 4.4

how much is 1kg of corn plus 1 cup of precooked corn ??​

Answers

Answer:

Step-by-step explanation:

It is not possible to accurately compare the weight of 1 kilogram of corn to 1 cup of precooked corn because the weight of the corn will change after it is cooked. Corn is composed of water, starch, and other nutrients, and the weight of the corn will change depending on how much water is retained in the kernels.

For example, 1 cup of uncooked corn kernels (about 168 grams) will yield about 1 1/4 cups of cooked corn (about 210 grams), while 1 cup of precooked corn (about 160 grams) will yield about 1 cup of cooked corn (about 160 grams).

Therefore, the weight of 1 kilogram of corn (about 1000 grams) is significantly greater than the weight of 1 cup of precooked corn (about 160 grams). It is not possible to accurately compare the weight of these two quantities because they are in different states (raw versus cooked) and have different densities.

Graph the line with y-intercept -7 and slope 3/2

Answers

We are given the slope and the y-intercept so using the slope-intercept form:

y = mx + b, where m- slope, b- y-intercept.

Substitute values to get:

y = (3/2)x - 7

To graph a line we need two points, one is given, (0, - 7) - the y-intercept.

Find one more point,  take even value of x to cancel the fraction, let it be x = 4, find its y-coordinate:

y = (3/2)*4  - 7 = 6 - 7 = - 1

So our points are:

A(0, - 7) and B(4, - 1)

Plot the points and connect to graph the line.

See below.

The graph of the linear equation:y = (3/2)*x - 7 can be seen in the image at the end.

How to graph the linear equation?

A general linear equation is written as:y = a*x + b

Where a is the slope and b is the y-intercept. Then our linear equation is:y = (3/2)*x - 7

To graph it, we need to know two points in our line, to do so, we evaluate it in two different values of x. if x = 0y = (3/2)*0 - 7y = -7So we have the point (0, -7)

And if x = 2 then:y = (3/2)*2 - 7y = 3 - 7y = -4So we have the point (2, -4)

Answer:

Arc QR = 48°; Arc RS = 96°x = 74/7; y = 15

Step-by-step explanation:

Given two inscribed quadrilaterals with various arcs and angles marked, you want to solve for specific unknown values.

1.

The measure of an inscribed angle is half the measure of the arc it intercepts. The sum of arcs of a circle is 360°.

  Arc PSR = 2·∠PQR = 2·93° = 186°

  Arc RS = Arc PSR -Arc PS = 186° -90° = 96°

  Arc QR = 360° -126° -90° -96° = 48°

The unknown arcs are ...

Arc QR = 48°Arc RS = 96°

2.

Opposite angles in an inscribed quadrilateral are supplementary:

  105° +(7x +1)° = 180°

  7x = 74 . . . . . . . . . . . divide by °, subtract 106

  x = 74/7 = 10 4/7 . . . . . divide by 7

The z* for a 95% confidence interval = 1.96

Setting up an equation,

[tex]1.96\sqrt{\frac{(0.5)^{2} }{x} } = 0.05[/tex]

Solving gives x=384.2.

Answers

a) The p-value indicates that it is very rare to observe a test statistics equally or more extreme when the null hypothesis is true.

What is null hypothesis?

A null hypothesis is a claim or presumption that there is no association between two observed variables or that observed differences between groups are the result of chance. It is frequently employed in statistical testing, and it is represented by the symbol "H0". The null hypothesis is often the inverse of the alternative hypothesis, which posits a link or difference between the variables. To reject the null hypothesis, the observed data must be statistically significant and unlikely to have occurred by chance. In scientific research, the null hypothesis is crucial because it enables researchers to assess the significance of their data and reach reliable conclusions.

7. Population Growth The population of a southern city
follows the exponential law.
(a) If N is the population of the city and is the time in
years, express N as a function of t.
(b) If the population doubled in size over an 18-month
period and the current population is 10,000, what will
the population be 2 years from now?
15

Answers

a) If N is the population of the city and is the time in years, N expressed as a function of t is; N(t) = N₀*e^(kt)

b) The population 2 years from now will be; 25198 people

How to solve the exponential growth model?

The general formula for exponential growth model is;

N(t) = N₀*e^(kt)

where;

f(x) is exponential growth function

N₀ is initial amount

t is time

k is constant

a) We are told that;

N is the population of the city.

t is the time in years

Thus, N expressed as a function of t is;

N(t) = N₀*e^(kt)

b) We are told that the population doubled in size over an 18-month

period . Thus, the equation would now be;

N(t) = N₀*2^(t/18)

Thus,  if the current population is 10000, then it means that 2 years from now, we will have;

N(2) = 10000 * 2^(24/18)

I used 24 because 2 years is 24 months

Thus;

N(2) ≈ 25198 people

Find the distance between the points $A\left(13,\ 2\right)$ and $B\left(7,\ 10\right)$ .

The distance between the two points is

Answers

The distance between the two points is 10 units

How to determine the distance between the two points?

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

A = (13, 2) and B =(7, 10)

The distance between the two points can be calculated using the following distance equation

distance = √[(x₂ - x₁)² + (y₂ - y₁)²]

Where

(x, y) = (13, 2) and (7, 10)

Substitute (x, y) = (13, 2) and (7, 10) in distance = √[(x₂ - x₁)² + (y₂ - y₁)²]

distance = √[(13 - 7)² + (2 - 10)²]

Evaluate

distance = 10

Hence, the distance is 10 units
