Answer:

Step-by-step explanation:

Step one:

given

selling price = $48

discount is 50%

tax= 4.5%

Step two:

let us first compute the amount in discount

=50/100*48

=0.5*48

=$24

also, let us compute the tax added

=4.5/100*48

=0.045*48

=$2.16

The total amount Garry has to pay is

=48-24+2.16

=$26.16

Step three:

If he has $25, he cannot afford the video game, he will have a deficit of $1.16

Answer: Gary will have to pay $25.08 in all, and if he has exactly $25, he can't afford to purchase the game because he only has $25, and he has to pay $25.08. $25.08 is more than $25, so he can't afford the game.

Step-by-step explanation:

First, subtract the $48 and 50% to find how much the video game costs.

So, $48-50%=24

Then, add the price of the video game, $24, to the 4.5% tax.

24+4.5%=25.08

Thus, Gary will need to pay $25.08 in all.

Answer:

The markup is 20.7 added along with 18, but the markup without the original price added is 2.7

Step-by-step explanation:

If you want step by step just comment and I’ll do it

Answer:

You need to multiply $2.70 cents is the answer. But with the markup, the price is $20.70

Step-by-step explanation:

You take the dollar amount, 18.00, and then multiply it by the percent, which we move the decimal since we are turning it into a decimal, since it is 15 we move the decimal two spots which makes it, 0.15.

The value of -175-15- (-204) is 14

We learn to add and subtract two or more integers or any other mathematical values using the two basic arithmetic operations of addition and subtraction. The plus sign (+) stands for addition, whereas the negative sign (-) stands for subtraction (minus sign). The opposite of addition is subtraction and vice versa.

The following are rules for addition and subtraction:

=>  \(+ \times + = +\)

=>  \(- \times - = +\)

=>  \(+ \times - = -\)

=>  \(- \times + = -\)  

Here we have

-175-15- (-204)

=> - 175 - 15 + 204

=>  - 190 + 204

=>  14

Therefore,

The value of -175-15- (-204) is 14

It is an isosceles triangle if two sides are same.

There are two possible triangles with given values.

If the 45° is between the two 8 cm sides, then as the isosceles triangle the other two angles have the measure:

So this is an acute triangle.

If the 45° angle is opposite to 8 cm side, then the other 8 cm side also has same opposite angle measure.

Then the third angle is:

It means it is a right triangle.

The expression x² + 8x + 16 represents the area of the square.

The area of the square is defined as the product of the length and width.

Given data as:

A square has a side length of (x+4)

The area of the square = (x+4)(x+4)

The area of the square = (x+4)²

The area of the square = x² + 2(x)(4) + 4²

The area of the square = x² + 8x + 16

Hence, the expression x² + 8x + 16 represents the area of the square.

Answer: Heyaa! ~

Your Answer is... 26.8

Step-by-step explanation:

The estimated answer is D. 27!

Hopefully this helps you! ^^

Answer:

27

Step-by-step explanation:

12.18 + 14.62= 26.80

if the number after the point is greater than 5 or equal to 5, we will add 1 to the number before the point, so now the number is 8 we will add 1 to the number before the point

26+1=27

therefore the sum of 12.18+14.62 = 27

Both \(det(s^(-1)as) and det(sas^(-1))\)are equal to 3.

To compute \(det(s^(-1)as) and det(sas^(-1))\), we can utilize the following properties and theorems:

The determinant of a product of matrices is equal to the product of their determinants: det(AB) = det(A) * det(B).

The determinant of the inverse of a matrix is the inverse of the determinant of the original matrix: \(det(A^(-1)) = 1 / det(A)\).

Using these properties, let's compute the determinants:

\(det(s^(-1)as)\):

Applying property 1, we have \(det(s^(-1)as) = det(s^(-1)) * det(a) * det(s).\)

Since s is invertible, its determinant det(s) is nonzero, and using property 2, we have \(det(s^(-1)) = 1 / det(s)\).

Combining these results, we get:

\(det(s^(-1)as) = (1 / det(s)) * det(a) * det(s) = (1 / det(s)) * det(s) * det(a) = det(a) = 3.\)

det(sas^(-1)):

Again, applying property 1, we have \(det(sas^(-1)) = det(s) * det(a) * det(s^(-1)).\)

Using property 2, \(det(s^(-1)) = 1 / det(s)\), we can rewrite the expression as:

\(det(sas^(-1)) = det(s) * det(a) * (1 / det(s)) = det(a) = 3.\)

Therefore, both \(det(s^(-1)as) and det(sas^(-1))\)are equal to 3.

I had this question a while ago.

The expected value of a gamble can be calculated by multiplying the probability of winning by the amount you could win and subtracting the probability of losing multiplied by the amount you could lose.

In this case, we are given that if a red card is drawn from a standard 52-card deck, you win $1200, and if a black card is drawn, you lose $1200.

First, let's determine the probability of drawing a red card from a standard 52-card deck. In a standard deck, there are 26 red cards (13 hearts and 13 diamonds) and 26 black cards (13 spades and 13 clubs). So the probability of drawing a red card is 26/52, which simplifies to 1/2 or 0.5.

Next, let's calculate the probability of losing, which is the probability of drawing a black card. Similarly, the probability of drawing a black card is also 26/52 or 1/2.

Now, we can calculate the expected value using the formula:
Expected value = (probability of winning * amount won) - (probability of losing * amount lost)

Expected value = (0.5 * $1200) - (0.5 * $1200)
Expected value = $600 - $600
Expected value = $0

Therefore, the expected value of the gamble is $0. This means that, on average, you neither win nor lose money in the long run by playing this gamble.

The value of K is 2.

Let's denote the scale factor as K. The surface area of a solid after dilation is directly proportional to the square of the scale factor.

We are given that the initial surface area of the solid is 50 units^2, and after dilation, the surface area becomes 200 units^2.

Using the formula for the surface area, we have:

Initial surface area * (scale factor)^2 = Final surface area

50 * K^2 = 200

Dividing both sides of the equation by 50:

K^2 = 200/50

K^2 = 4

Taking the square root of both sides:

K = √4

K = 2

Therefore, the value of K is 2.

The IQR of 13 is the most accurate measure of variability to represent the data, as it provides a more accurate representation of the typical donations received by the charity.

The range is the difference between the highest and lowest values in a dataset.

In this case, the range is,

⇒ 49 - 10 = 39.

However, the range is sensitive to outliers, which can skew the data and make it less representative of the typical donations received.

The IQR is a measure of variability that is less sensitive to outliers than the range.

It is the difference between the third quartile (Q3) and the first quartile (Q1) of the dataset.

In this case, Q1 = 42

and Q3 = 49,

so the IQR is ,

IQR = 49 - 42

IQR = 7.

The IQR represents the middle 50% of the data and is a good measure of the spread of the typical donations received by the charity.

Therefore, the IQR of 13 is the most accurate measure of variability to represent the data, as it provides a more accurate representation of the typical donations received by the charity.

1.

The central angle is 3π/4

The length of an arc, L = rФ where

Making Ф subject of the formula, we have

Ф = L/r

Since L = 6π and r = 8, substituting the values of the variables into the equation, we have

Ф = L/r

Ф = 6π/8

Ф = 3π/4

The central angle is 3π/4

2.

The length of the intercepted arc is 55π/6 ft

Also, the length of an arc, L with central angle, Ф in degrees is

L = Ф/360 × 2πr where r = radius of circle

Since Ф = 110° and r = 15 ft, substituting the values of the variables into the equation, we have

L = Ф/360 × 2πr

L = 110°/360° × 2π × 15 ft

L = 11/36 × 30π ft

L = 11/6 × 5π ft

L = 55π/6 ft

Sean must read at least 66 more pages to reach his goal of reading at least 80 pages by the end of the week.

Let's say the number of pages Sean needs to read is x.

he has already read 14 pages and wants to read at least 80 pages by the end of the week.

We can write this as an inequality:

x + 14 ≥ 80

To solve this inequality, we need to isolate x.

First, we subtract 14 from both sides of the inequality:

x + 14 - 14 ≥ 80 - 14

This simplifies to:

x ≥ 66

So, Sean must read at least 66 more pages to reach his goal of reading at least 80 pages by the end of the week.
