Option A) Buying a laptop will be most affordable among all the options as per the Selling price with Sales tax included.

The selling price is the price at which a thing is sold. Typically, it is identified as SP. also known as a selling price on occasion.

Shop owners essentially mark this as a promotional item to give discounts to customers in a way that,

When a product is sold to a buyer, the government levies sales tax (abbreviated as ST). This tax will be collected by the merchant and paid to the government. As a result, it is added to the bill after being charged on the item's selling price.

For Laptop,

Selling Price = (100-40)% of 2399.99

                     = 60% of 2399.99 = $ 1439.99

Total bill = 1439.99 + 8.2% of 1439.99

For Smart TV,

Selling Price = (100-10)% of 1799.99

                     = 90% 0f 1799.99 = $ 1619.99

Total bill = 1619.99 + 4.5% of 1619.99

               = 1619.99 + 72.9 = $ 1692.89

For Iphone,

Selling Price = (100-5)% of 1699.99

                     = 95% 0f 1699.99 = $ 1614.99

Total bill = 1614.99 + 6.8% of 1614.99

               = 1614.99 + 109.82 = $ 1724.81

For GeForce RTX 3090 Graphics Card,

Selling Price = 2199.99 - 500 = $ 1699.99

Total bill = 1699.99 + 7.5% of 1699.99

               = 1699.99 + 127.5 = $ 1827.49

Using the the Distributive Property to express 64 + 24 is 88.

This property states that multiplying the sum of two or more addends by a number produces the same result as multiplying each addend separately by the number and then adding the products together.

When you multiply a value by a sum, the distributive property of multiplication over addition is used. For instance, suppose you want to multiply 5 by the sum of 10 + 3. When we have similar terms, we usually add the numbers first and then multiply by 5. 5(10 + 3) = 5(13) = 65.

In this case, 64 + 24 will be;

a) The percentile of the phone that sold for $330 is; 29%

b) The sales price at 75th percentile is; $425

In statistics, a percentile is a term that describes how a score compares to other scores from the same set.

From the given set of data showing the sales prices, let us sort them out from smallest to largest;

Sort the data values from smallest to largest:

235, 299, 300, 304, 325, 325, 330, 345, 355, 355, 370, 400, 400, 405, 415, 415, 425, 430, 449, 450, 495

It should be noted that 6 of the 21 data values are smaller than 325.

The percentile is then the number of data values that are less than the individual's data value divided by the number of data values in total, written as a percentage.

Thus;

Percentile = (Total number of data values/Number of data values that are less than the individual’s data value) × 100%

= 6/21  × 100%

≈ 0.2857 × 100%

= 28.57 % ≈ 29%

At 75th percentile, we have;

0.75 = x/21

x = 21 * 0.75

x = 15.75

Thus, the selling price of the phone at the 75th percentile is greater than 16 of the 21 phones. This phone has a selling price of at least $425

There are 210 sequences for 7 church bells to rung with the given conditions. Using permutations, the required number of sequences is calculated.

A sequence or arrangement that can be framed by taking some or all of a finite set of things (or objects) is called a permutation.

The formula for finding the number of such arrangements is,

ⁿPₓ = n!/(n - x)!

It is given that, a church's bell tower has 7 bells. 3 of them will ring in a sequence before each service and no bell is rung more than once.

So, the number of sequences that the bells will form is calculated by using the permutations formula. I.e., ⁿPₓ = n!/(n - x)!

Here, n = 7; x = 3

Then,

ⁿPₓ = n!/(n - x)! ⇒ ⁷P₃ = 7!/(7 - 3)! = 7!/4!

⇒ ⁷P₃ = (7 × 6 × 5 × 4!)/4! = 7 × 6 × 5 = 210

Therefore, there are 210 sequences for ringing the bells.

Answer:

  1180 cm³

Step-by-step explanation:

You want the volume of a prism with an L-shaped base. It is 20 cm between bases. The outside dimensions of the L are 7 cm high by 11 cm wide; the inside dimensions are 3 cm high by 6 cm wide.

The formula for the volume of a prism is ...

  V = Bh

where B is the area of the base, and h is the distance between them. We know h, but we need to find B.

The area of an L-shape is the area of the rectangle with the outside dimensions, less the area of the rectangle with the inside dimensions.

  A = LW -lw

  A = (11 cm)(7 cm) -(6 cm)(3 cm) = 77 cm² -18 cm² = 59 cm²

Using the above formula, the volume is ...

  V = (59 cm²)(20 cm) = 1180 cm³

The volume of the prism is 1180 cubic centimeters.

__

Additional comment

The dimensions of the inside of the L are found by subtracting the given width of the legs from the outside dimensions.

 7 cm -4 cm = 3 cm . . . . inside height

  11 cm -5 cm = 6 cm . . . . inside width

You can also find the area of the base by extending one or the other of the lines to divide it into two rectangles. Extending the vertical line makes the left rectangle 7 cm high by 5 cm wide. The right rectangle is 4 cm high by 6 cm wide. Then the area is 7·5 +4·6 = 35+24 = 59, as above.

Answer:

36%

Step-by-step explanation:

People with size 7 shoes = 5

People with size 7½ = 7

People with size 8 = 9

People with size 8½ = 3

People with size 9 = 1

To find out the total, you have to add all the people up:

5 + 7 + 9 + 3 + 1 = 25

The total amount of students = 25

Since you're trying to find the percentage of students who have a shoe size of 8, you have to look at how many people have that size:

People with size 8 = 9

To find out the percentage you do:

9/25 × 100 = 36%

Therefore 36% of students have a shoe size of 8

As per the congruence theorem, we have proved that ΔABC ≅ΔDEF.

In math congruence theorem states that if all the three sides of one triangle are equal to all the three sides of another triangle, then both the triangles are congruent to each other.

Here we need to prove ΔABC ≅ΔDEF by using the congruence theorem.

Here we have given that ΔABC and ΔDEF,

=> ∠B≅∠E [right angle]

So, we have obtained that

=> ∠A≅∠D

As we know that there is two angles and one non included side of ΔABC is congruent the two corresponding angles and one non- included side of ΔDEF, therefore, by AAS congruence rule.

So, based on the given fact we have identified that

=> ΔABC ≅ΔDEF

Therefore, the AAS congruence postulate defined that the triangles are congruent if two pairs of corresponding angles and a pair of opposite sides are equal in both triangles.

Answer:

x/78 = 55/100

Step-by-step explanation:

Answer:

Step-by-step explanation:

To prove this statement, we can use the contrapositive. The contrapositive of the statement "If a + b > 100, then a, b, or both must be greater than 50" is "If a and b are both less than or equal to 50, then a + b is less than or equal to 100."

To prove the contrapositive, we must show that if a and b are both less than or equal to 50, then a + b is indeed less than or equal to 100. This is easy to do, because if a and b are both less than or equal to 50, then the largest possible value for a is 50 and the largest possible value for b is 50. Therefore, the largest possible value for a + b is 50 + 50, which is equal to 100.

Since the contrapositive is true, it follows that the original statement must also be true. Therefore, we have proven that if a + b > 100, then a, b, or both must be greater than 50.

Using the Pythagorean theorem, we know that the roof of the building is 24 ft far from the ground.

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between a right triangle's three sides in Euclidean geometry.

According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

So, the Pythagorean theorem formula:

c² = a² + b²

Now, substitute the values in the formula to calculate the distance between the roofline and the ground.

c² = a² + b²

25² = a² + 7²

625 = a² + 49

a² = 625 - 49

a² = 576

The solution to the linear equation 3(x + 5) = 1/9 is

x = -4 26/27.

The correct answer is option D; None of these choices are correct.
