Your water is 5/6 full. After Tennis Practice, the bottle is 3/8 full. How much water did you drink?

Answer:

1.  45, 51

2. 40, 52

3. -64, 128

4. 63.5, 63.75

Step-by-step explanation:

1. It is adding 6 each time.

2. It adds 2, then 4, then 6, each time adding an extra 2 units. (another way to explain is, the original term, 2, that they add is multiplied by 2 each time)

3. It multiplies by -2 each time.

4. It adds 16, then 8, then 4, dividing the term that is added by 2 each time.

Attention:

I didn't do the bottom half of the homework, I will leave that for someone else to get the points. I hope this helps you. :)

Answer: A

Step-by-step explanation: You know multiplying will be involved, so B can automatically be removed. It states that the length is 8 cm longer. You know absolutely nothing about the width, so the variable of w can be given for the width. You also know the length will be 8 cm longer, of w+8. w and w+8 will be multiplied, which gives you w(w+8).

Answer:

w(w+8)=48

Step-by-step explanation:

Answer:

GH = 96

Step-by-step explanation:

Since G is at the midpoint of RH then RG = SH and

GH = 7x - 23

Thus

RG + GH = RH ← substitute values

7x - 23 + 7x - 23 = 6x + 90

14x - 46 = 6x + 90 ( subtract 6x from both sides )

8x - 46 = 90 ( add 46 to both sides )

8x = 136 ( divide both sides by 8 )

x = 17

Hence

GH = 7x - 23 = (7 × 17) - 23 = 119 - 23 = 96

Answer:

96

Step-by-step explanation:

Drawing a picture helps to think this problem through. 2(7x-23)=6x+90 by midpoint theorem. Solve this equation.

14x-46=6x+90

8x=136

x=17

Substitute x in the equation for RG. 7(17)-23.

7x17=119

119-23=96

Answer: 7000

Step-by-step explanation:

In the given figures figure C has no line of symmetry. Hence, option C is correct.

The line of symmetry is an imaginary line that divides an object into two equal and identical halves.

It is a reflectional symmetry, meaning that each point on one side of the line corresponds to an identical point on the other side.

This line can be vertical, horizontal, or even diagonal, depending on the shape or object being considered.

The line of symmetry is an important concept in geometry and can be found in various symmetrical objects like letters, shapes, and even faces.

If we rotate Figure C with respect to any axis we don't get an identical shape.

Therefore,

Figure C has no line of symmetry.

Final answer:

To finish reading 1 million pages while reading 1000 pages a month, it would take the student 1000 months.

Explanation:

To calculate how long it would take to finish reading 1 million pages, we need to find the number of months required. Since the student reads 1000 pages a month, we can set up a proportion:

1000 pages / 1 month = 1 million pages / x months

Cross-multiplying gives:

1000x = 1 million

Dividing both sides by 1000:

x = 1000 months

Therefore, it would take the student 1000 months to finish reading 1 million pages.

Answer:

100 % - 65% = 35%

this means that 63.00 is 35% the original price

cross multiply:

$63 35%

$x 100%

100 * 63 = 6300

------------ ---------- = $180

35 35

original price $180

The original price, 100% of an item at the store is $180.00.

A percentage is a number or ratio that can be expressed as a fraction of 100. Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.

For the given situation,

Amount paid by Joyce = $63.00

Consider the original price be 100%

65 percent off the original price = [tex]100 - 65[/tex]

⇒ [tex]35[/tex]

So, 35% of an item is $63.00

The original price 100% can be calculated as

⇒ [tex]\frac{63(100)}{35}[/tex]

⇒ [tex]\frac{63100}{35}[/tex]

⇒ [tex]180[/tex]

Hence we can conclude that the the original price, 100% of an item at the store is $180.00.

Answer:

decrease = 26.04

increase = 29.96

Step-by-step explanation:

Decrease of £28.00 by 7% = £28 -(7% of 28)

                                             = £28 - (0.07 × 28)

                                             = £28 - 1.96

                                             = £26.04

Increase of £28 by 7% = £28 +(7% of 28)

                                      = £28 +(0.7 × 28)

                                      = $28 + 1.96

                                      = £29.96

Decrease £28 by 7% would be £26.04

and increase £28 by 7% would be £29.96

Answer:

the answer would be $3,582 dollars i hope u geta good grade and your welcome :3

Answer: The cost would be $1782 and $3582 respectively.

Step-by-step explanation:

Since we have given that

Number of MP3 players = 18

Number of CD/MP3 = 18

Cost of each MP3 = $99.00

Cost of each CD/MP3 = $199.00

So, the Cost of 18 MP3 would be

[tex]18\times 99\\\\=\$1782[/tex]

And, the cost of 18 CD/MP3 would be

[tex]199\times 18\\\\=\$3582[/tex]

Hence, the cost would be $1782 and $3582 respectively.

Part 1) [tex]f(2)=1[/tex]

Part 2) [tex]f^{-1}(1)=2[/tex]

part 3) [tex]f^{-1}(f(2))=2[/tex]

Step-by-step explanation:

we have that

[tex]f(x)=\frac{1}{2}x[/tex]

[tex]f^{-1}(x)=2x[/tex]

Part 1) Find f(2)

For x=2

substitute the value of x in f(x)

[tex]f(2)=\frac{1}{2}(2)[/tex]

[tex]f(2)=1[/tex]

Part 2) find [tex]f^{-1}(1)[/tex]

For x=1

Substitute the value of x in [tex]f^{-1}(x)[/tex]

[tex]f^{-1}(1)=2(1)[/tex]

[tex]f^{-1}(1)=2[/tex]

Part 3) Find [tex]f^{-1}(f(2))[/tex]

we know that

[tex]f(2)=1[/tex] -----> see part 1)

so

[tex]f^{-1}(f(2))=f^{-1}(1)[/tex]

we have that

[tex]f^{-1}(1)=2[/tex] -----> see part 2)

therefore

[tex]f^{-1}(f(2))=2[/tex]

Given that, the perimeter of a rectangular room=60 feet.

The formula to find the perimeter of the rectangle is 2(l+b).

Where, l=length and b=width.

Let x be the width of the room (in feet) and let y be the length of the room (in feet).

So, 60=2(x+y)

⇒x+y=30

The volume of a cube can be calculated with the following formula:

[tex]V=s^3[/tex]

Where "s" is the length of each edge of the cube.

Solving for "s":

[tex]s=\sqrt[3]{V}[/tex]

Let's check each option to find which volume would work according to the size she needs:

A. Substitute [tex]V=216in^3[/tex] into [tex]s=\sqrt[3]{V}[/tex], then:

[tex]s=\sqrt[3]{216in^3}=6in[/tex]

B. Substitute [tex]V=125in^3[/tex] into [tex]s=\sqrt[3]{V}[/tex], then:

[tex]s=\sqrt[3]{125in^3}=5in[/tex]

C. Substitute [tex]V=64in^3[/tex] into [tex]s=\sqrt[3]{V}[/tex], then:

[tex]s=\sqrt[3]{64in^3}=4in[/tex]
