Answer:

$8.50

Step-by-step explanation:

This is a division problem.

You need to divide $25.50 by 3.

25.5/3 = 8.5

Answer: Each sister pays $8.50.

Answer:

$8.50

Step-by-step explanation:

Since the gift is $25.50, including tax, and there are three sisters, divide the cost of the gift ($25.50) by the number of sisters (3) to find how much each one of them has to pay.

25.50 ÷ 3

= $8.50

Each sister should pay $8.50.

Answer:

the question should have something in between 6 and x

The number must be added in the expression, x² - 8x, to make a perfect square trinomial is 16.

Perfect square trinomials are algebraic representations that have three terms and are formed by multiplying a binomial by another binomial. A perfect square is a number formed by multiplying another number by itself.

The form is ax² + bx + c.

Where, a, b, and c are real numbers & a ≠ 0.

Now, as per the question; the expression is given as;

x² - 8x

The perfect square trinomial written in standard form as;

(x - a) = x²  - 2ax + a²

In the given equation, enter c as the value to be added.

x² - 8x + c

By comparing it to the standard form

-8x = - 2ax ----->(1)

c = a2----->(2)

When we solve these equations for a and c, we get

-8x = - 2ax

a = -8/-2

a = 4

c = (4)² = 16

Thus,

(x - 4)² = x² - 8x + 16

As a result, the value that must be added is 16.

Although part of your question is missing, you might be referring to this full question: The stadium has 15400 seats and it is to be renovated with a new seating capacity of 20790 seats. After renovation what will be the percentage increase in the number of seats?

The initial capacity of the stadium  = 15400 seats

Planned new capacity = 20790 seats

Increment in the number of seats = 20790 - 15400 = 5390 seats

Percentage increase in the number of seats = (Increment in seats/Initial capacity of the stadium)*100

Therefore,

(5390/15400)*100 = 0.35*100 = 35%

So the percentage increase in the number of seats after renovation will be 35%

Between the locations S(4,-3) and T(-2,2), there are 7.81 units between them.

The length of the line segment connecting two locations serves as a measure of the distance between them. Most importantly, the distance between two points is always positive and segments with the same length are known as congruent segments.

P(x1, y1) and Q(x2, y2) are two points, and the formula for their distance is provided by: d (P, Q) = (x2 - x1)2 + (y2 - y1) 2.

The points S(4,-3) and T are given.

Therefore, the distance (d) between S(4,-3) and T(-2,2) is as follows:

⇒ d (S, T) = √

² + (2 - (-3)) ².

⇒ d (S, T) = √ (-6)² + (5) ².

The original dimensions of the piece of metal are 39 inch by 24 inches.

Let the breadth of the rectangular piece be b inches.

Hence, according to the data given in the question,

Length of the rectangular piece will be (b + 15) inches.

After 4 squares of 3 inches each are cut from the corners of the rectangular piece, the length and breadth of the piece becomes:-

Length = b + 15 - 3 - 3 = (b + 9) inches

Breadth = b -3 -3 = (b - 6) inches

The height of the subsequent open box made will be 3 inches.

We have,

Volume of the cuboidal open box = 1782 cubic inches.

Also, we know that,

Volume of cuboid = l*b*h

Where,

l is the length,

b is the breadth, and

h is the height

Hence,

(b+9)(b-6)(3) = 1782 cubic inches

(b+9)(b-6) = 1782/3 = 594

We can write 594 as 33*18

Hence,

(b+9)(b-6) = 33*18

b+9 = 33 or b-6 = 18

b = 33-9 = 18+6 = 24

The values of r and s is -1 and -4 respectively.

Given that:-

coordinates of j are (-8,-5)

coordinates of l are (6,-11)

coordinates of k are (r-4,2s)

Also, k is the mid-point of jl.

We have to find the values of r and s.

We know that, for  (x,y) and (z,w), the mid-point is ((x+z)/2, (y+w)/2).

Here,

(x,y) = (-8.-5)

(z,w) = (6,-11)

(r-4,2s) = ((x+z)/2,(y+w)/2)

Hence,

(r-4,2s) = ((-8+6)/2,(-5-11)/2)

(r-4,2s) = (-1,-8)

Comparing the coordinates, we get:-

r - 4 = -1

r = -1+4 =3
