Answer:

$1680

Step-by-step explanation:

1500=100%

100+12(interest)=112

112=1.12(multiplier)

1500×1.12=$1680

Answer:

0.78 s

Step-by-step explanation:

Since the position of the pool is at 60 feet below, s(t) = -60 for both me and Anna. So, both expressions for the motion of the book are equated to -60 and then solved to find the time they reach the water.

So, For me s(t)= −16t² + 60

-60 = −16t² + 60

collecting like terms, we have

-60 - 60 = −16t²

- 120 = −16t²

dividing both sides by - 16, we have

t² = -120/-16

t² = 7.5

t = √7.5

t = 2.74 s

For Anna, s(t)= −16t² - 30t + 60

-60 = −16t² - 30t + 60

adding 60 to both sides, we have

-60 + 60 = −16t² - 30t + 60 + 60

−16t² - 30t + 120 = 0

dividing through by -2, we have

8t² + 15t - 60 = 0

Using the quadratic formula to find t

[tex]t = \frac{-15 +/- \sqrt{15^{2} - 4 X 8 X -60} }{2 X 8} \\t = \frac{-15 +/- \sqrt{225 + 1920} }{16} \\t = \frac{-15 +/- \sqrt{2145} }{16} \\t = \frac{-15 +/- 46.31}{16} \\t = \frac{-15 - 46.31}{16} or t = \frac{-15 + 46.31}{16} \\t = \frac{-61.31}{16} or t = \frac{31.31}{16} \\t = -3.83 s or 1.96 s[/tex]

Since t' cannot be negative, t' = 1.96 s.

It takes Anna's book 1.96 s to reach the water, while it takes 2.74 s for my book to reach the water.

So, the time it takes Anna's book to beat mine is the difference between the time of reaching the water of each book. So Δt = t - t' = 2.74 s - 1.96 s = 0.78 s

Answer:

[tex]\frac{M-3c}{b}=a[/tex]

Step-by-step explanation:

[tex]M=ab+3c\\M-3c=ab\\\frac{M-3c}{b}=a[/tex]

Answer:

[tex]\frac{m - 3c}{b} = a[/tex]

Step-by-step explanation:

m = ab + 3c

-3c        - 3c

m - 3c = ab

[tex]\frac{m - 3c}{b} = \frac{ab}{b}[/tex]

[tex]\frac{m - 3c}{b} = a[/tex]

Answer:

a. The answers obtained are as follows:

Frequency for flossing 7 times per week = 24

Relative frequency for flossing 4 times per week = 0.1231

Cumulative Frequency at flossing 1 time per week = 22

b. The Cumulative Relative Frequency at flossing 7 time per week is 100%.

Step-by-step explanation:

Note: This question is not complete and the data in it are merged together. The complete question is therefore provided with the sorted data before answering the question. See the attached pdf file for the complete question.

The explanation to the answers is now provided as follows:

a. Complete the table (Use 4 decimal places when applicable)

Note: See part a of the attached excel for the complete table (answers are in bold red color)

Frequency is the rate at which something or an event occurs in a particular sample.

Since we already have frequency for others flossing times per week and we have 130 adults as the sample, the frequency for flossing 7 times per week is calculated by deducting the frequencies of others from 130 as follows:

Frequency for flossing 7 times per week = 130 – 10 – 12 – 14 – 18 – 16 – 21 – 15 = 24

Relative Frequency refers to the fraction of times an event occurs. The relative frequencies in this question are calculated by dividing each frequency by the total number of adults in the sample, i.e. 130. The relative frequency for flossing 4 times per week is therefore calculated as follows:

Relative frequency for flossing 4 times per week = Frequency for flossing 4 times per week / Total number of adults in the sample = 16 / 130 = 0.1231

Cumulative Frequency is calculated by adding the current frequency to the previous Cumulative Frequency. The Cumulative Frequency at flossing 1 time per week is therefore calculated as follows:

Cumulative Frequency at flossing 1 time per week = Cumulative Frequency at flossing 0 time per week + Frequency at flossing 1 time per week = 10 + 12 = 22

b. What is the cumulative relative frequency for flossing 7 times per week? %

Note: See part b of the attached excel for the complete table (answer is in bold red color)

The cumulative relative frequency refers to the accumulation of the previous relative frequencies.

Cumulative Relative Frequency is calculated by adding the current relative frequency to the previous Cumulative Relative Frequency. It should be noted that the first cumulative relative frequency equal to the first relative frequency.

The Cumulative Relative Frequency at flossing 7 time per week is therefore calculated in the attached excel file as follows:

Cumulative Relative Frequency at flossing 1 time per week = Cumulative Relative Frequency at flossing 6 times per week + Relative Frequency at flossing 7 times per week = 0.8154 + 0.1846 = 1.0000

Since the question indicates that the Cumulative Relative Frequency at flossing 7 time per week should be stated in percentage term, we therrefore have:

Cumulative Relative Frequency at flossing 7 time per week = 1.0000 * 100 = 100%.

Answer:

Do not post random subjects in mathematics.

Also, pain is temporary.

If you end your life you just pass it onto someone else.

Try to find people online that understand you. The reason why you can't do anything is because you keep telling yourself that. This sounds cringe but try new things and venture. Try meditation or yoga. If you aren't an open person then you can do breathing exercises in private. While you take in your breath think positively. I hope this advice can help you! Never give up!

Answer:

1) Please find attached the diagram showing the answer to the question

The area of the diagram is (3x + 1)(x + 2) = 3 dark green squares + 7 light green squares + 2 Plain squares

∴ (3x + 1)(x + 2) = 3·x² + 7·x + 2

2) When x = 1, (1 + 4)² = 25 ≠ 2 × 1² + 8 × 1 + 8 = 18

Therefore, (x + 4)² is not equivalent to 2·x² + 8·x + 8

Step-by-step explanation:

1) In the attached diagram, we have;

For x = 1

(3x + 1)(x + 2) = (3 + 1)(1 + 2)

Therefore, the length of the sides of the rectangle are;

Height = 4, and Width = 3

For x = 1, x² = 1² = 1

∴ 3·x² = 3, 7·x = 7 × 1 = 7, and 2 = 2

Therefore, from the diagram, we have;

The area = (3x + 1)(x + 2) = 3 dark green squares + 7 light green squares + 2 Plain squares

∴ (3x + 1)(x + 2) = 3·x² + 7·x + 2

The diagram for when x = 3 is also included

2) For (x + 4)², we have;

When x = 1, (x + 4)² = (1 + 4)² = 25

However;

When x = 1, 2·x² + 8·x + 8 = 2 × 1² + 8 × 1 + 8 = 18

Therefore;

(x + 4)² is not equivalent to 2·x² + 8·x + 8

1) Please find attached the diagram showing the answer to the question

The area of the diagram is (3x + 1)(x + 2) = 3 dark green squares + 7 light green squares + 2 Plain squares

2) When x = 1, (1 + 4)² = 25 ≠ 2 × 1² + 8 × 1 + 8 = 18

Therefore, (x + 4)² is not equivalent to 2·x² + 8·x + 8

Answer:

-7/8

Step-by-step explanation:

change the denominator and numerator of -1/2 by multiplying both by 4.

Then you get -4/8 instead of -1/2. This allows you to then subtract the -3/8 with -4/8 which equals -7/8.

Answer:

1) Bigger sector = 168.8pi

1) Smaller sector = 56.3pi

2) Bigger sector = 529.9

3) Smaller sector = 176.6

Step-by-step explanation:

1) Bigger sector =  [tex]\frac{270}{360}[/tex]×pi×15×15

                          = 168.75pi

1) Smaller sector = [tex]\frac{360-270}{360}[/tex]×pi×15×15

                             = [tex]\frac{90}{360}[/tex]×pi×15×15

                             = 56.25pi

2) Bigger sector =  [tex]\frac{270}{360}[/tex]×3.14×15×15

                           = 529.875

2) Smaller sector = [tex]\frac{360-270}{360}[/tex]×3.14×15×15

                             = [tex]\frac{90}{360}[/tex]×3.14×15×15

                             = 176.625

Answer:

y=2 x=5

Step-by-step explanation:

3x-2y=11

2x-3y=4

you multiply both equations to cancel one variable out. in this case you multiply the first equation by 2 and the second by -3

     6x-4y=22

+    -6x-9y=12

--------------------------

0x+5y=10

y=2

you plug that in either equation

3x-2(2)=11

3x-4=11

3x=15

x=5

Answer:

1. After solving we get value of x: [tex]\mathbf{x=\frac{6}{11} }[/tex]

2. After solving we get value of x: [tex]\mathbf{x=\frac{6}{11} }[/tex]

Step-by-step explanation:

We need to Solve the equations.

1.  [tex]10 - 6 x = 4 + 5 x[/tex]

Step 1: Subtract 5x on both sides

[tex]10 - 6 x-5x = 4 + 5 x-5x\\10-11x=4[/tex]

Step 2: Subtract 10 on both sides

[tex]10-11x-10=4-10\\-11x=-6[/tex]

Step 3: Divide both sides by -11

[tex]\frac{-11x}{-11}=\frac{-6}{-11}\\x=\frac{6}{11}[/tex]

So, after solving we get value of x: [tex]\mathbf{x=\frac{6}{11} }[/tex]

2. [tex]7-6x=1+5x[/tex]

Step 1: Subtract 5x on both sides

[tex]7 - 6 x-5x = 1 + 5 x-5x\\7-11x=1[/tex]

Step 2: Subtract 7 on both sides

[tex]7-11x-7=1-7\\-11x=-6[/tex]

Step 3: Divide both sides by -11

[tex]\frac{-11x}{-11}=\frac{-6}{-11}\\x=\frac{6}{11}[/tex]

So, after solving we get value of x: [tex]\mathbf{x=\frac{6}{11} }[/tex]
