Answer:

25 2/15

Step-by-step explanation:

A = length x width

width is 4 1/6

35 = 4 1/6 x length

solve for length

divide both sides by 4 1/6

35 divided by 4 1/6  or multiply 35 x 6/25 (reciprocal)

210/25

8 10/25 = 8 2/5 is the length

to find perimeter 2xlength + 2xwidth

2 x 4 1/6 + 2 x 8 2/5 = 2 x 25/6 + 2 x 42/5 = 50/6 + 84/5

convert to common denominator and add

use 30 as common denominator

250/30 + 504/30= 754/30

25 4/30 or 25 2/15

Final answer:

To find the perimeter of the rectangle, calculate the length using the given area and width. Then, apply the perimeter formula P = 2l + 2w. The perimeter is approximately 25.1 feet.

Explanation:

Calculating the Perimeter of a Rectangle

To find the perimeter of a rectangle, you need to know both the width and the length of the rectangle. The perimeter is the total distance around the rectangle, which is the sum of twice the width and twice the length: P = 2l + 2w.

The width of the rectangle is given as 4 1/6 feet. To find the length, we can use the provided area of the rectangle which is 35 square feet. The area of a rectangle is found by multiplying the length by the width: A = l × w. Let's call the length 'l'.

First, convert the width to an improper fraction: 4 1/6 = (4 × 6 + 1)/6 = 25/6 feet. Now set up the equation using the area: 35 = (25/6) × l. Solving for 'l' gives us l = (35 × 6)/25 = 210/25 = 8.4 feet.

Now that we have the length, calculate the perimeter using the equation P = 2l + 2w:

P = 2 × 8.4 + 2 × 4 1/6

P = 16.8 + 2 × 25/6

P = 16.8 + 50/6

P = 16.8 + 8.333...

P = 25.133... feet

Therefore, the perimeter of the rectangle is approximately 25.1 feet when rounded to one decimal place.

Answer:

d^2 - π(d/2)^2

Step-by-step explanation:

Since the diameter of the circle is equal to the side of a square (d), that means that we have a circle inscribed in square.

If we draw a square and inscribe a circle in it, all parts of the square outside the circle will be waste, in this particular case.

If we want to find the area of the wasted material we need to subtract the area of the circle from the area of the square.

Area of the circle is:

P1 = πr^2, r being the radius

Since radius is half the diameter, that means that:

P1 = π • (d/2)^2

Area of the square whose side is d is:

P2 = d^2

So, the area of wasted material is:

P = P2 - P1

P = d^2 - π(d/2)^2

- Monthly premium (9% of annual): $240.00 * 9% = $21.60

**Whole Life Policy:**

- Annual premium: $652.50

- Semiannual premium (51% of annual): $652.50 * 51% = $332.775 (approximately $332.78)

- Quarterly premium (26% of annual): $652.50 * 26% = $169.50

- Monthly premium (9% of annual): $652.50 * 9% = $58.725 (approximately $58.73)

**20-Payment Life Policy:**

- Annual premium: $945.00

- Semiannual premium (51% of annual): $945.00 * 51% = $482.475 (approximately $482.48)

- Quarterly premium (26% of annual): $945.00 * 26% = $245.70

- Monthly premium (9% of annual): $945.00 * 9% = $85.05

**20-year Endowment Policy:**

- Annual premium: $1,346.10

- Semiannual premium (51% of annual): $1,346.10 * 51% = $686.761 (approximately $686.76)

- Quarterly premium (26% of annual): $1,346.10 * 26% = $350.286 (approximately $350.29)

- Monthly premium (9% of annual): $1,346.10 * 9% = $121.15

The average speed is 135.26 miles per hour

Solution:

Given that, woman traveled 2445.9 miles in 18 hours five minutes

To find: Average speed of her flight in miles per hour

Let us first convert 18 hours 5 minutes to hours

We know that,

[tex]1 \text{ minute } = \frac{1}{60} \text{ hour }[/tex]

Therefore,

[tex]5 \text{ minute } = \frac{5}{60} \text{ hour } = 0.083 \text{ hour }[/tex]

Thus we get,

18 hours five minutes = 18 hour + 0.083 hour = 18.083 hour

Given that, distance = 2445.9 miles

Average speed is given by formula:

[tex]Average\ speed = \frac{distance}{time}\\\\Average\ speed = \frac{2445.9}{18.083}\\\\Average\ speed = 135.26[/tex]

Thus average speed is 135.26 miles per hour

Answer:

Students= 6

Teachers= 2

Step-by-step explanation:

Given: Art museum trip:

           Cost of ticket= $5.5 per teacher and $3 per student.

           Total amount paid= $29.

           Science trip:

           Cost of ticket= $22 per teacher and $11.5 per student.

           Total amount paid= $113.

Lets assume number of teacher be "x" and number of students be "y".

Now, forming an equation for cost of each trip.

we know, total cost= [tex]cost\ of \ each\ ticket \times numbers\ of\ tickets[/tex]

∴Art museum trip, [tex]5.5x+3y= 29[/tex] ---- 1st equation

Science museum trip, [tex]22x+11.5y= 113[/tex] ---- 2nd equation

Next using elimination method to find number teacher and students

[tex]5.5x+3y= 29\\22x+11.5y= 113[/tex]

Multiplying both side of 1st equation by 4

∴ [tex]22x+12y= 116\\22x+11.5y= 113[/tex]

changing sign of 2nd equation on both side and solving it.

∴ [tex]0.5y= 3[/tex]

Dividing both side by 0.5

[tex]y= \frac{3}{0.5}= 6[/tex]

Hence, number of students on field trip was 6.

Subtituting the value of y in 1st equation to find the number of teachers in field trip.

[tex]5.5x+3y= 29[/tex]

⇒ [tex]5.5x+3\times 6= 29[/tex]

⇒ [tex]5.5x+18= 29[/tex]

Subtracting both side by 18

⇒ [tex]5.5x= 11[/tex]

Dividing both side by 5.5

⇒ [tex]x= \frac{11}{5.5}= 2[/tex]

Hence, there were 2 teachers on field trips.

Answer:16 books

Step-by-step explanation:

Final answer:

Julian bought 8 books and received a free book with each purchase, resulting in 16 books altogether by the end of the year.

Explanation:

The question is asking how many books Julian would have altogether if he bought 8 books and received a free book with each purchase this year. To solve this, we need to consider that for every book purchased, he gets an additional book without cost. Therefore, Julian gets 2 books each time he makes a purchase for one book. As he bought 8 books, we simply need to double that amount to account for the free books he received.

To calculate: 8 books purchased × 2 = 16 books altogether.

Julian would have a total of 16 books by the end of the year after his purchases and receiving the complementary books.

Answer:

D

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (8, - 1), thus

y = a(x - 8)² - 1

To find a substitute (0, - 17), the coordinates of the y- intercept into the equation.

- 17 = a(0 - 8)² - 1

- 17 = 64a - 1 ( add 1 to both sides )

- 16 = 64a ( divide both sides by 64 )

a = [tex]\frac{-16}{64}[/tex] = - [tex]\frac{1}{4}[/tex]

y = - [tex]\frac{1}{4}[/tex](x - 8)² - 1 → D

Question:

Which scenario best matches the linear relationship expressed in the equation y = –14x + 1,700?

1) Kent has $1,700 in his bank account and spends $14 each week.

2) Kent has $1,700 in his bank account and deposits $14 each week.

3) Kent had $1,700 in his bank account and deposited another $14.

4) Kent has $14 in his bank account and spent $1,700.

Answer:

Option  1) Kent has $1,700 in his bank account and spends $14 each week.

Step-by-step explanation:

Let x denote the number of weeks.

Option 1: Kent has $1,700 in his bank account and -14x as the negative sign denotes how much amount he spend each week.

Thus, Option 1 is the correct answer.

Option 2: Kent has $1,700 in his bank account and deposits $14 each week.

Writing it as equation, we have, [tex]y=14x+1700[/tex] which is not the expressed linear equation.

Hence,  Option 2 is not the correct answer.

Option 3: Kent had $1,700 in his bank account and deposited another $14.

Writing it as equation, we have, [tex]y=14+1700[/tex] which is not the expressed linear equation.

Hence,  Option 3 is not the correct answer.

Option 4: Kent has $14 in his bank account and spent $1,700.

Writing it as equation, we have, [tex]y=14-1700[/tex] which is not the expressed linear equation.

Hence,  Option 4 is not the correct answer.

Thus, the scenario that matches the linear equation relationship expressed in the equation is Option 1.

since there are 4 pieces of wood, you will have 4 combinations.  since the sum of the 2 shortest sides need to be more than the longest side the inequalities above are valid.

Hope this helps!!

Final answer:

Out of the four lengths of wood provided, there are three valid combinations that can form triangles: 4 cm, 5 cm, 6 cm; 4 cm, 6 cm, 7 cm; and 5 cm, 6 cm, 7 cm. These combinations satisfy the Triangle Inequality Theorem, which is necessary for forming triangles.

Explanation:

To determine how many different combinations of 3 pieces of balsa wood can be used to make triangles, we must recall the Triangle Inequality Theorem which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the remaining side. For the pieces of lengths 4 cm, 5 cm, 6 cm, and 7 cm, we can form the following combinations that satisfy the Triangle Inequality Theorem:

4 cm, 5 cm, 6 cm

4 cm, 6 cm, 7 cm

5 cm, 6 cm, 7 cm

The inequalities for these combinations are as follows:

4 cm + 5 cm > 6 cm

4 cm + 6 cm > 5 cm

5 cm + 6 cm > 4 cm

4 cm + 7 cm > 6 cm

6 cm + 7 cm > 4 cm

5 cm + 7 cm > 6 cm

Each of these combinations is valid as the sum of the lengths of any two pieces is greater than the length of the third piece.

Step-by-step explanation:

given: [tex]f(x) = 2(3)^{x}[/tex]

substitute some values for x and see which curves accurately reflect the corresponding y-values:

when x = 0, f(0) = 2(3)^0 = 2(1) = 2

hence the graph must pass through the point (0,2)

We can see from the choices that the 2nd and 4th graphs do not pass through (0,2), so we can eliminate these 2 from consideration

when x = 1, f(1) = 2(3)^1= 2(3) = 6

hence the graph must pass through the point (1,6)

We can see that the 3rd graph does not pass through this point so we can eliminate the 3rd graph also.

Only the 1st graph gives points consistent with the 2 cases above.

Answer: 90

Step-by-step explanation:

The formula for calculating the nth term of a sequence is given as :

[tex]t_{n}[/tex] = a + ( n - d )

Where a is the first term

d is the common difference and

n is the number of terms

This means that the 4th term of an arithmetic sequence will have the formula :

[tex]t_{4}[/tex] = a + 3d

And the 4th term has been given to be , 12 ,substituting into the formula we have

12 = a + 3d .............................. equation 1

Also substituting for the 8th term , we have

36 = a + 7d .............................. equation 2

Combining the two equations , we have

a + 3d = 12  ................... equation 1

a + 7d = 36 ------------ equation 2

Solving the system of linear equation by substitution method , make a the subject of formula from equation 1 , that is

a = 12 - 3d ................... equation 3

substitute a = 12 - 3d into equation  2 , equation 2 then becomes

12 - 3d + 7d = 36

12 + 4d = 36

subtract 12 from both sides

4d = 36 - 12

4d = 24

divide through by 4

d = 6

substitute d = 6 into equation 3 to find the value of a, we have

a = 12 - 3d

a = 12 - 3 ( 6)

a = 12 - 18

a = -6

Therefore , the 17th term of the sequence will be :

[tex]t_{17}[/tex] = a + 16d

[tex]t_{17}[/tex] = -6 + 16 (6)

[tex]t_{17}[/tex] = -6 + 96

[tex]t_{17}[/tex] = 90

Therefore : the 17th term of the sequence is 90

Answer:

  ≈ 58

Step-by-step explanation:

Estimation usually means you want an answer good to one or maybe two significant figures. That usually means you want to round the numbers involved to one or two significant figures.

Doing that here transforms the problem to 180/3 = 60, an answer with one significant figure.

You can improve the estimate a bit by recognizing that it is a little high (the numerator is higher than 175.32, but the denominator is the same). Since the numerator is high by about 5, the estimate is high by about 5/3 or a little less than 2. A closer estimate will be 60 - 2 = 58.

_____

The degree to which you refine the estimate will depend on the error requirements you have. Certainly an estimate of 60 is within 10% of the true value, so is "close enough" for many purposes.

To estimate 175.32 by 3, round 175.32 to 175, and divide by 3 to get 58. Since 175 is just under 180, which divides evenly by 3 to give 60, an estimate of 58 is reasonable.

To estimate the division of 175.32 by 3, we can round the numbers to make the calculation easier. First, we round 175.32 to 175 which is very close in value, and 3 remains as it is because it is already a whole number. So, our estimation becomes 175 / 3.

Dividing 175 by 3 gives us 58 as 3 times 58 is 174. We can see that this approximation is just 1 less than our rounded number, so it is a reasonable estimate. Therefore, 175.32 / 3 is approximately 58 when we estimate it without a calculator.

To check our estimation, we can compare it to similar, simple calculations. For example, if we divide 180 by 3, we get 60. Since 175 is slightly less than 180, our estimation of 58 is likely a good approximation for the division of 175.32 by 3.
