Answer:

Slope m = 2

Step-by-step explanation:

Buying from World Stationery shop would profit Gigi.

Given,

Gigi is going to buy 100 stickers.

Stickers4u - Pack of 25 stickers for £2.25

World Stationery - Pack of 10 stickers for £1.75

Buy 1 pack get 1 pack 1 free

Solution:

Cost of 1 sticker in Stickers4u = £2.25/25 stickers = £0.09

Cost of 1 sticker in World Stationery = £1.75/ 10 stickers = £0.175

Since it is mentioned, 'Buy 1 pack get 1 pack 1 free' in this shop, the total no of stickers one would get for the price would be doubled.

Hence,

Cost of 1 sticker in World Stationery would be = £1.75/ 20 stickers = £0.0875

On comparing the price per sticker of both the shops, we can say that

buying from World Stationery shop would profit Gigi.

Answer: C

Explanation:

The range of a function is the set of all values of y that satisfy the function. On the graph, it is between the lowest value of y at the bottom and the highest value of y at the top. Looking at the graph, it extends to negative infinity at the bottom and the maximum value at the top y = 4

Thus, in interval notation,

Range = (- ∞, 4]

If In a class of 30 students, 13 have a brother and 8 have a sister. There are 3 students who have a brother and a sister. The probability that a student who has a sister also has a brother is: 3/10.

Given data:

Total number of student = 30

Brother = 13

Sister = 8

Brother and sister = 3

Now let determine the probability that  a student has brother and sister using this formula

P ( S n B ) = Brother and sister  / Total number of student

Let plug in the formula

P ( S n B ) = 3/30

Therefore we can conclude that 3/30 is the probability.

The amount of sales tax on Finnegan's purchase is $5.94

The first step is to calculate the total amount of purchase

Sweater- $29.50

Jeans- $42.50

Total amount

29.50 + 42.50

= 72

The sales tax rate is 8.25%

The amount of sales tax on the purchase can be calculated as follows

8.25/100 × 72

= 0.0825 × 72

= 5.94

Hence the sales tax on the total purchase is $5.94

Reflection

Step-by-step explanation:

A line, called the line of reflection, will allow an image to reflect through it. Every point in a figure is said to mirror the other figure when they are all equally spaced apart from one another. The reflected picture should have the same size and form as the original, but it faces the opposite way. The opposing signs are created from the coordinates. Changes in posture during contemplation may also result in translation. Pre-image and image are terms used to refer to the same thing in this context.

A gallon = 4 quarts
4 quarts = 4 x 2 = 8 pints.
8 pints = 8 x 16 = 128 (ounces)

So, a gallon equals 128 ounces.

Generally, 2 cups = 1 pint.

The absolute value equation with the solutions -3.75 and 3.75 is:

|x| = 3.75

The general absolute value equation can be written as:

|x+ a| = b

And this can be rewritten into two equations, which are:

x + a = b

x + a = -b

In this case, we want to get an absolute value function such that the two solutions are -3.75 and 3.75, this is ratter trivial to do, we can write the next absolute value function:

|x| = 3.75

If we decompose this, we will get the two equations:

x = 3.75

x = -3.75

Which are the two solutions we wanted.

The maximum price Charlie and Linus are wiling to pay to enter each park is 10.5 dollars.

Charlie Brown and Linus are so excited for Halloween that they have planned trips to three different parks.

They are willing to pay no more than $40 to go to all of them.

Jones’ Corn Maze has an entry fee that is $4 less than double the amount of Tomilloso’s Pumpkin Patch entrance fee.

King’s Haunted House has an entry fee that is $2 more than Tomilloso’s Pumpkin Patch.

let

x = amount of Tomilloso’s Pumpkin Patch entrance fee

Therefore,  the inequality that represent the situation is as follows;

Jones’ Corn Maze an entry fee = 2x - 4

King’s Haunted House entry fee = 2 + x

Therefore,

2x - 4 + 2 + x + x ≤ 40

4x - 2 ≤ 40

add 2 to both sides of the inequality

4x - 2 + 2 ≤ 40 + 2

4x ≤ 42

Answer:

Step-by-step explanation:

The highest price of house that Holly can afford is £343350.

In mathematics, the tax calculation is related to the selling price and income of taxpayers. It is a charge imposed by the government on the citizens for the collection of funds for public welfare and expenditure activities. There are two types of taxes: direct tax and indirect tax.

Given that, Holly can afford to spend, including Land Transaction Tax, is £327000.

Here, the tax rate is 5% because that is above £250000 and below £400000.

Let x be the highest price of house that Holly can afford.

x= 327000+5% of 327000

x= 327000+5/100 ×327000

x= 327000+0.05×327000

x= £343350

Therefore, the highest price of house that Holly can afford is £343350.

The average rate of change over the interval is 10 and it tells us about the slope

The definition of the function is given as

f(x) = 2.5xsquared + 3

Rewrite the function properly

So, we have the following equation

f(x) = 2.5x² + 3

The interval to calculate the average rate of change is given a

0 ≤ x ≤ 4

This can be represented as

[0, 4]

Further, rewrite as

[a, b] = [0, 4]

Where a = 0 and b = 4

Calculate f(a) and f(b)

So, we have

f(0) = 2.5(0)² + 3 = 3

f(4) = 2.5(4)² + 3 = 43

The average rate of change is then calculated as

Average rate = [f(b) - f(a)]/[b - a]

Substitute the known values in the above equation

So, we have

Average rate = [43 - 3]/[4 - 0]

Evaluate

Average rate = 10

The average rate is the slope of the function

This means that it represents the amount of change in the function with respect to the change in the input variables

If both Santi and Vlado drove for the same amount of time with Santi driving at 75% of Vlado's average speed, and they covered 1304 miles in 24 hours, then Santi had driven for approximately 559 miles.

As per the question statement, Santi and Vlado drove together from New York to New Orleans. Both of them drove for  the same amount of time with Santi driving 75% as quickly as Vlado, and it took them 24 hours to complete the 1304 miles journey.

We are required to calculate the approximate number of miles, that Santi drove during their trip.

Since given that, Both of them drove for  the same amount of time and it took them 24 hours to complete the 1304 miles journey, therefore, both Santi and Vlado drove for (24/2) = 12 hours each.

Now, let us consider that Vlado drove at an average speed of "v" miles/hour.

Then, Santi would have driven at a average speed of [(75/100)v] m/h

                                                                                      = (0.75v) m/h

                                                                                      = 0.75V miles/hour

[Since Santi drove 75% as quickly as Vlado]

Now as we know that, [(speed * time) = distance], applying the same formula to the velocities and driving times of Santi and Vlado, we get,

[{(12 * v) + (12 * 0.75v)} = 1304]

Or, [(12v + 9v) = 1304]

Or,(21v = 1304)

Or, v = [(1304/21)]

Or, (v = 62.095 miles/hour)

Or, (v ≈ 62.1 miles/hour)

That is, Vlado drove at an average speed of 62.1 miles per hour,

And, Santi drove at an average speed of (62.1 * 0.75) miles per hour

                                                                 = (46.575) miles per hour.

Therefore, Santi drove a total of (46.575 * 12) = 558.9 miles ≈ 559 miles,

as he drove at an average speed of 46.575 miles per hour, for 12 hours.
