To find how far Jace walked to school each day, divide the total distance (5/6 of a mile) by the number of days (5), resulting in 1/6 of a mile walked each day.

Explanation:

The question involves calculating the distance Jace walked to school each day if he walked a total of 5/6 of a mile over 5 days. To find out how far he walked each day, we need to divide the total distance by the number of days.

Here's the step-by-step calculation:

Total distance walked: 5/6 of a mile.

Number of days: 5 days.

To find the distance walked each day, divide the total distance by the number of days: (5/6) ÷ 5 = 5/6 ÷ 1/5 = 5/30 = 1/6.

So, Jace walked 1/6 of a mile to school each day.

The number 4.4354 correct to 2 decimal places is 4.44. The third digit, 5, indicates that the second decimal place is rounded up.

The question is asking to write the number 4.4354 correct to 2 decimal places. When you're rounding a number to a certain number of decimal places, you look at the digit in the next spot decimal place. In this case, for two decimal places, we look at the third decimal. If this number is 5 or above, we 'round up' the second decimal place by one digit. If it is less than 5, we leave it as is. The third digit in this case is 5, so we 'round up' meaning the number 4.4354 written correct to 2 decimal places is 4.44.

To find the width of the track, add up the lengths of all the inside and outside arcs and subtract the total length of the inside arcs from the total length of the outside arcs.

To find the width of the track, we first need to determine the difference between the inside and outside arcs of each piece. Let's assume the outside arc has a length of A inches. According to the question, the inside arc is 3.4 inches shorter than the outside arc. Therefore, the inside arc has a length of A - 3.4 inches.

Since there are ten identical pieces forming the circular track, we can add up the lengths of all the inside arcs and all the outside arcs to find the total distance covered by the track. The width of the track is then the difference between the total length of the outside arcs and the total length of the inside arcs.

Let's express the width of the track as a function of A. The total length of the outside arcs is 10A inches, and the total length of the inside arcs is 10(A - 3.4) inches. Therefore, the width of the track is:

Width = 10A - 10(A - 3.4) inches.

In an arithmetic sequence, the common difference is constant. In a geometric sequence, the terms are obtained by multiplying the previous term by a constant ratio. In this case, the value of y in the sequence is 3 for an arithmetic sequence and 9 for a geometric sequence.

In an arithmetic sequence, the difference between consecutive terms is constant. To find the value of y in the sequence 2, 8, 3y + 5, we observe that the common difference is 8 - 2 = 6. Therefore, we can set up the equation 8 - 2 = 3y + 5 - 8 to solve for y. Simplifying, we get 6 = 3y - 3. Solving for y, we have y = 3.

In a geometric sequence, each term is obtained by multiplying the previous term by a constant ratio. To find the value of y in the sequence 2, 8, 3y + 5, we need to determine the common ratio. We can see that the ratio between 8 and 2 is 8/2 = 4. Therefore, we can set up the equation 8/2 = (3y + 5)/8 to solve for y. Simplifying, we get 4 = (3y + 5)/8. Multiplying both sides by 8, we have 32 = 3y + 5. Solving for y, we get y = 9.

Answer:

B) it includes points in quadrant ii

The graph of f(x) must include points in quadrants II and IV. Therefore, option B is the correct answer.

A function is such that f(−x) =−f (x) where the sign is reversed but the absolute value remains the same if the sign of the independent variable is reversed.

So,

The points in quadrants II are in IV.

The points in quadrants I are in III.

From the question, we understand that graph includes the points in IV.

This means that these points are also in quadrant II.

Hence, the graph of f(x) must include points in quadrants II and IV.

The result of the division is:

[tex]\[\boxed{4x^2 - 10x + 11 + \frac{6}{2x + 5}}\][/tex]

To find [tex]\( \frac{f(x)}{g(x)} \)[/tex] where [tex]\( f(x) = 8x^3 - 28x + 61 \)[/tex] and [tex]\( g(x) = 2x + 5 \)[/tex], we need to perform polynomial division.

Polynomial Division

1. Divide the leading term of the dividend by the leading term of the divisor:

 [tex]\[ \frac{8x^3}{2x} = 4x^2 \][/tex]

2. Multiply the entire divisor by this result and subtract from the dividend:

[tex]\[ 8x^3 - 28x + 61 - (4x^2 \cdot (2x + 5)) = 8x^3 - 28x + 61 - (8x^3 + 20x^2) \][/tex]

  Simplifying, we get:

[tex]\[ -20x^2 - 28x + 61 \][/tex]

3. Repeat the process with the new polynomial:

 [tex]\[ \frac{-20x^2}{2x} = -10x \][/tex]

4. Multiply the entire divisor by this result and subtract:

[tex]\[ -20x^2 - 28x + 61 - (-10x \cdot (2x + 5)) = -20x^2 - 28x + 61 - (-20x^2 - 50x) \][/tex]

  Simplifying, we get:

[tex]\[ 22x + 61 \][/tex]

5. Repeat the process again:

  [tex]\[ \frac{22x}{2x} = 11 \][/tex]

6. Multiply the entire divisor by this result and subtract:

[tex]\[ 22x + 61 - (11 \cdot (2x + 5)) = 22x + 61 - (22x + 55) \][/tex]

  Simplifying, we get:

 [tex]\[ 6 \][/tex]

Putting it all together, we have:

[tex]\[\frac{f(x)}{g(x)} = 4x^2 - 10x + 11 + \frac{6}{2x+5}\][/tex]

So, the result of the division is:

[tex]\[\boxed{4x^2 - 10x + 11 + \frac{6}{2x + 5}}\][/tex]

Final answer:

To find the total height of Stephan's sculpture with the base, we add the heights represented by fractions with a common denominator to get an overall height of 11/12 feet.

Explanation:

To determine the overall height of Stephan's sculpture with the base, we simply need to add the height of the sculpture to the height of the base. The sculpture is 7/12 foot tall and the base is 1/3 foot tall. To add these two fractions together, we need to find a common denominator, which is 12 in this case. So, we convert 1/3 foot into 4/12 foot. Now we can add the two fractions:

7/12 + 4/12 = 11/12 feet

Therefore, the combined height of the sculpture and the base is 11/12 feet.

The ordered pairs lie on the graph of the exponential function is (3, 16).

The formula f(x) = [tex]a^x[/tex]defines an exponential function, where x is the input variable as an exponent. The exponential curve is determined by the exponential function and the value of x.

We have,

f(x) = 180 (0.5[tex])^x[/tex]

Now, for x = 0,

So, f(x) = 128(0.5[tex])^0[/tex]

= 128(1)

= 128

Now, for x = 1,

f(x) = 128(0.5[tex])^1[/tex]

= 128(0.5)

= 256

Now, for x = 3,

f(x) = 128(0.5[tex])^3[/tex]

= 128(1/8)

= 16

So, the correct ordered pair is (3, 16).

Answer: Option 'D' is correct.

Step-by-step explanation:

Since we have given that

Amount of Kevin's gross income = $45942

Amount he contribute to his retirement plan = $3435

Amount he lost in business losses = $3393

Amount he incurred in business expenses = $1128

So, His adjusted gross income will be

[tex]45942-(3435+3393+1128)\\\\=45942-(7956)\\\\=\$37986[/tex]

Hence, his adjusted gross income is $37,986.

Answer:

Step-by-step explanation:

Use proportions to figure this out.  On the top you'll have miles and on the bottom you'll have minutes.  I am going to change 3/4 to .75 and 1/8 to .125:

[tex]\frac{miles}{minute}:\frac{.75}{.125}[/tex]

We want to know how many miles per 1 minute that is.  So we have the unknown on top in a new ratio, with 1 on the bottom:

[tex]\frac{miles}{minute}:\frac{.75}{.125}=\frac{x}{1}[/tex]

This second ratio is allowing us to calculate what the decimal ratio is in miles per 1 minute.  Cross multiply to get

.125x = .75 so

x = 6 miles

That tells us that the decimal ratio is equivalent to 6 miles per minute
