All basketballs at a sporting goods store were marked down 25% during the first week of a sale. During the third week, all remaining basketballs were marked down an additional 30%. If a basketball was originally $22, how much does it cost during the third week?

Answer:

[tex]Area = 3\dfrac{15}{16}\ sq\ ft[/tex]

Area is greater than [tex]3\frac{1}{2}[/tex] sq ft.

Step-by-step explanation:

Length of rectangular sign board = [tex]3\frac{1}{2}[/tex] ft

Width of rectangular sign board = [tex]1\frac{1}{8}[/tex] ft

Area of a rectangle is given by the formula:

[tex]A = Length \times Width[/tex]

To find the area, we are going to multiply [tex]3\frac{1}{2}[/tex] with [tex]1\frac{1}{8}[/tex].

[tex]1\frac{1}{8}[/tex] is greater than 1.

Therefore the multiplication will be greater than [tex]3\frac{1}{2}[/tex].

Hence, we can say that area will be greater than [tex]3\frac{1}{2}[/tex] sq ft.

Area of the sign:

[tex]A = 3\dfrac{1}{2}\times 1\dfrac{1}8\\\Rightarrow A = \dfrac{7}{2}\times \frac{9}8\\\Rightarrow A = \dfrac{63}{16}\\\Rightarrow A = 3\dfrac{15}{16}\ sq\ ft[/tex]

Answer:

4L + 8H = 512 (First answer)

You can take 92 low resolution pictures (second answer)

Step-by-step explanation:

Let L represent the number of low resolution pictures you take and H the number of high resolution pictures you can take.

You only have 512 megabytes.

Therefore, the number of megabytes the low resolution pictures you take plus the amount of megabytes the high rsolution you take in total should be 512

Therefore your equation is:

4L + 8H = 512 (First answer)

You took 18 high resolution pictures, so substitute 18 for H

4L+8(18) = 512

4L+144=512

subtract 144 on both sides

4L=368

divide by 4

L= 92

You can take 92 low resolution pictures

Step-by-step explanation:

Properties of a kite;

1). A kite has one pair of equal angles.

2). A kite has two pairs of adjacent sides.

3). Diagonals of a kite intersect at 90°.

4). Kite has at least one diagonal that bisects the opposite angles.

It's given in the question,

m∠ABC = 70° and m∠ADC = 46°

By the property number -4,

m∠2 = m∠3 = [tex]\frac{70}{2}[/tex] = 35°

m∠8 = m∠9 = [tex]\frac{46}{2}[/tex] = 23°

By the property number - 3,

m∠4 = 90°

By the property of interior angles in a triangle,

m∠3 + m∠4 + m∠5 = 180°

35° + 90° + m∠5 = 180°

125° + m∠5 = 180°

m∠5 = 55°

Similarly, m∠1 + m∠2 + 90° = 180°

m∠1 + 35° + 90° = 180°

m∠1 = 55°

Now m∠6 + 90° + m∠8 = 180°

m∠6 + 90° + 23° = 180°

m∠6 = 180 - 113 = 67°

Therefore, m∠6 = m∠7 = 67°

The values of all 9 angles shown were found using the property of a kite they are:

∠1=55°

∠2=35°

∠3=35°

∠4=90°

∠5=55°

∠6=67°

∠7=67°

∠8=23°

∠9=23°

One pair of equal angles, two pairs of equal adjacent sides, diagonals intersect at a right angle.

∠1=∠6 because AB=AC

∠6=∠7 because AD=DC

∠2=∠3 because triangle ABC is a combination of two congruent triangles.

∠8=∠9 because triangle DAC is a combination of two congruent triangles.

∠4=90°diagonals intersecting at the right angle.

It is given that

∠2+∠3 = 70°

Since they are equal so ∠2=∠3=35

∠8+∠9 = 46°

Since they are equal so ∠8=∠9=23°

∠5 = 180-∠3-∠4 = 180-35-90=55°

Similarly, ∠1 = 55°

∠6+∠7 = 180-∠8-∠9 = 180-46 = 134°

Since they are equal

∠6=∠7 = 67°

Therefore, all 9 angles were calculated using property of a kite.

∠1=55°

∠2=35°

∠3=35°

∠4=90°

∠5=55°

∠6=67°

∠7=67°

∠8=23°

∠9=23°

Answer:

Step-by-step explanation:

180-86= 94

Given:

The function in the form of set of points is

[tex]s:\{(4,3),(5,3),(8,6),(9,6),(12,9),(13,9)\}[/tex]

To find:

(a) The inverse of function s.

(b) whether the inverse of function s is a function?

Solution:

(a)

If a function is [tex]f:\{(a,b),a,b\in R\}[/tex], then its inverse function is

[tex]f^{-1}:\{(b,a),a,b\in R\}[/tex]

We have,

[tex]s:\{(4,3),(5,3),(8,6),(9,6),(12,9),(13,9)\}[/tex]

So, inverse of this function is

[tex]s^{-1}:\{(3,4),(3,5),(6,8),(6,9),(9,12),(9,13)\}[/tex]

Therefore, the inverse of function s is [tex]s^{-1}:\{(3,4),(3,5),(6,8),(6,9),(9,12),(9,13)\}[/tex].

(b)

A set of point is a function if there exist unique output for each input.

In inverse of s, we have two output values y=4 and y=5 for single input x=3.

Therefore, the inverse of function s is not a function.

Step-by-step explanation:

Vertex form of the quadratic function

If the graph of the quadratic function has a vertex at the point (h,k), then the function can be written as:

[tex]y=a(x-h)^2+k[/tex]

Where a is the leading coefficient.

We are given the following function:

[tex]y =-2x^2-4x+7[/tex]

To find the vertex, we need to complete squares. First, factor -2 on the first two terms:

[tex]y =-2(x^2+2x)+7[/tex]

The expression in parentheses must be completed to represent the square of a binomial. Adding 1 and subtracting 1:

[tex]y =-2(x^2+2x+1- 1)+7[/tex]

Taking out the -1:

[tex]y =-2(x^2+2x+1)+2+7[/tex]

Factoring the trinomial and operating:

[tex]y =-2(x+1)^2+9[/tex]

Comparing with the vertex form we have

Vertex (-1,9)

Leading coefficient: -2

Since the leading coefficient is negative, the function has a maximum value at its vertex, i.e.

Maximum: (-1,9)

Answer:

10t + 400 would be the answer.

Step-by-step explanation:

every hour, there would be 10 gallons added to the pool, so time should be the letter "t" in the equation.

Also, there's already 400 gallons of water existing in the pool, so we need to add 400 gallons.

Therefore, 10t + 400 would be the answer.

The missing step for solution of the expression is,

⇒ Divide both sides of the equation by 10.4.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Now, We have been given an expression:

2.3 + 8(1.3x - 4.75) = 629.9  

Hence, We will solve the above equation for x as;

First distribute the parenthesis over 8 we get:

2.3 + 10.4x - 38 = 629.9

Now, subtract 2.3 on right hand side of the above equation we get:

10.4x - 38 = 629.9 - 2.3

10.4 x = 627.6 + 38

10.4 x = 665.6

Hence, the last step would be divide by 10.4 to get the value of x

x = 64

Therefore, option 4th is correct.
