Simplify 12.70-n+9+n/4

The waffle cone has a larger radius compared to the sugar cone.

The radius of a cone can be found using the formula:

radius = volume / height / pi

Both cones have the same volume of 12 ounces, so we can use this formula to compare their radii:

For the waffle cone: radius = 12 / 5 / pi = 0.766

For the sugar cone: radius = 12 / 8 / pi = 0.477

Therefore, the waffle cone has a larger radius compared to the sugar cone.

The waffle cone has a larger radius of approximately 2.03 inches compared to the sugar cone's radius of approximately 1.61 inches.

To determine which cone has a larger radius, we need to calculate the radius of each cone using the volume formula for a cone. Since both cones hold the same volume (12 ounces), we'll convert this to cubic inches (since 1 ounce is approximately 1.8 cubic inches, 12 ounces is roughly 21.6 cubic inches).

The volume formula for a cone is:

V = (1/3)πr²h

Where V is the volume, r is the radius, and h is the height.

Waffle Cone:

Volume (V) = 21.6 cubic inches
Height (h) = 5 inches

Therefore, we have:

21.6 = (1/3)πr²(5)

Solving for r, we get:

21.6 = (5/3)πr²
r² = 21.6 / ((5/3)π)
r² = 12.97 / π
r ≈ sqrt(4.13)
r ≈ 2.03 inches

Sugar Cone:

Volume (V) = 21.6 cubic inches
Height (h) = 8 inches

Therefore, we have:

21.6 = (1/3)πr²(8)

Solving for r, we get:

21.6 = (8/3)πr²
r² = 21.6 / ((8/3)π)
r² = 8.1 / π
r ≈ sqrt(2.58)
r ≈ 1.61 inches

Comparing the two radii, the waffle cone has a larger radius of approximately 2.03 inches, while the sugar cone has a smaller radius of approximately 1.61 inches.

Final answer:

Equivalent fractions for 3/8 could be 6/16 or 12/32, and for 1/4, they could be 2/8 or 4/16, achieved by multiplying both the numerator and denominator by the same number.

Explanation:

The student asked which pairs of fractions are equivalent to 3/8 pound of Swiss cheese and 1/4 pound of American cheese. To find equivalent fractions, we multiply or divide both the numerator and the denominator of the fraction by the same number. For example, if we multiply the numerator and denominator of 3/8 by 2, we get 6/16, which is equivalent to 3/8. Likewise, if we multiply the numerator and denominator of 1/4 by 2, we get 2/8 which is equivalent to 1/4. Another pair of equivalent fractions can be found by multiplying 3/8 and 1/4 each by 4, resulting in 12/32 and 4/16 respectively.

Answer:A

Step-by-step explanation:

The equation that best set up the quadratic formula is [tex]x = \frac{ -(-2) |+-| \sqrt{(-2)^2-4(1)(4)} }{2(1)}[/tex].

Hence, option A is the correct answer.

Quadratic equation is simply an algebraic expression of the second degree in x. Quadratic equation in its standard form is;

ax² + bx + c = 0

Where x is the unknown

Using the quadratic formula

x = (-b±√(b² - 4ac)) / (2a)

Given that;

x² + 1 = 2x – 3

First we re-arrange the the equation.

x² + 1 = 2x - 3

x² - 2x + 1 + 3 = 0

x² - 2x + 4 = 0

Hence;

Next we input this values into the quadratic formula

x = (-b±√(b² - 4ac)) / (2a)

x = (-(-2)±√((-2)² - 4(1)(4))) / (2(1))

[tex]x = \frac{ -(-2) |+-| \sqrt{(-2)^2-4(1)(4)} }{2(1)}[/tex]

The equation that best set up the quadratic formula is [tex]x = \frac{ -(-2) |+-| \sqrt{(-2)^2-4(1)(4)} }{2(1)}[/tex].

Hence, option A is the correct answer.

Answer:

The word sum corresponds to addition, which means:

d + 12 = 20

:)

Answer: d + 12 = 20

Step-by-step explanation: In this problem, we are asked to write an algebraic expression that represents the sentence.

The key to understanding this problem is by looking at the keyword "sum." The word sum means addition so reading this problem from left to right, the sum of d and 12 that's d + 12 "is 20" = 20.

So, d + 12 = 20 will be our algebraic expression.

Answer: [tex]A(t)=-8t+52[/tex]

Step-by-step explanation:

The  equation of the line in Slope-Intercept form is:

[tex]y=mx+b[/tex]

Where "m" is the slope and "b" is the y-intercept.

According to the data given in the exercise, you know that:

- [tex]A(t)[/tex] represents the area to paint the Hiros' romm as a function of time.

- The rate he painted the room was 8 square meters per hour.

- The area left to paint after 3 hours was 28 m².

Therefore, based on this, you can idenfity that:

1. The slope of the line is:

[tex]m=-8[/tex]

2. One of the point on the line is:

[tex](3,28)[/tex]

So you must substitute the slope and the coordinates of that point into [tex]y=mx+b[/tex] and then solve for "b" in order to find its value:

[tex]28=-8(3)+b\\\\28+24=b\\\\b=52[/tex]

Therefore, you can determine that the function [tex]A(t)[/tex] is:

[tex]A(t)=-8t+52[/tex]

Answer: [tex]\frac{(x+4)(x+1)}{x+2}[/tex]

Step-by-step explanation:

The area of a rectangle [tex]A[/tex] is given by the multiplication of its base [tex]b[/tex] by its height [tex]h[/tex]:

[tex]A=(b)(h)=x^{2}+5x+4[/tex] (1)

In addition we are told the length of one of the sides (let's choose [tex]b[/tex]) is:

[tex]b=x+2[/tex] (2)

Substituting (2) in (1):

[tex](x+2)h=x^{2}+5x+4[/tex] (3)

Isolating [tex]h[/tex]:

[tex]h=\frac{x^{2}+5x+4}{(x+2)}[/tex]

Factoring in the numerator:

[tex]h=\frac{(x+4)(x+1)}{x+2}[/tex] This is the length of the other side of the rectangle

Answer:

A. [tex]\displaystyle 10\:units[/tex]

Step-by-step explanation:

Use the Distance Formula:

[tex]\displaystyle \sqrt{[-x_1 + x_2]^2 + [-y_1 + y_2]^2} = D \\ \\ \sqrt{[-3 + 2]^2 + [-6 - 4]^2} = \sqrt{[-1]^2 + [-10]^2} = \sqrt{1 + 100} = \sqrt{101} ≈ 10,04987562 ≈ 10[/tex]

Since we are talking about distance, we ONLY want the NON-NEGATIVE root.

I am joyous to assist you anytime.

Final answer:

The approximate length of a line segment connecting points A(3, 6) and B(2, -4) is found using the distance formula and it is approximately 10 units.

Explanation:

To calculate the approximate length of a line segment connecting points A and B, we use the distance formula. The distance formula is derived from the Pythagorean theorem and is:

d = \/((x2 - x1)² + (y2 - y1)²)

Given points, A(3, 6) and B(2, -4), we can plug these coordinates into the formula:

d = \/((2 - 3)² + (-4 - 6)²)

Now, calculate the squares and sum:

d = \/((-1)² + (-10)²)

d = \/(1 + 100)

d = \/(101)

The square root of 101 is approximately 10.05, which is close to 10 units.
Therefore, the approximate length of the line segment connecting points A and B is 10 units, which corresponds to option A.

Step-by-step explanation:

1,115.625 miles in 21 hrs and 15 min.....

15 minutes = 15/60 = 0.25 hrs......so they did it in 21.25 hrs

1,115.625 / 21.25 = 52.5 miles per hr <===

Answer:

see the explanation

Step-by-step explanation:

we have the points

(4,7) and (4,-3)

we know that

The x=coordinate of both points are the same

so

the line that goes through those two points is a vertical line (parallel to the y-axis)

The slope is undefined

Because

The formula to calculate the slope between two points is equal to

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

substitute the values

[tex]m=\frac{7+3}{4-4}[/tex]

[tex]m=\frac{10}{0}[/tex]

Is undefined (the denominator is equal to zero)

see  the attached figure to better understand the problem

Answer:

Step-by-step explanation:

Sample Response: Since both points have the same x-coordinate, the line would be vertical. A vertical line has no slope because the run of the graph, which is the denominator, is zero and therefore an undefined fraction.

Answer:

The correct answer is A. 12 minutes.

Step-by-step explanation:

Let's solve for y, when x = 12, as follows:

y = 175 - 15x

y = 175 - 15 * 12

y = 175 - 180

y = - 5

This result means that after 12 minutes the fish tank would be completely drained and if it's needed 5 additional gallons of water could also be drained. It's not necessary to continue making more calculation with the the other options given because this is the right answer.

the two solutions are approximately [tex]\( x_1 \approx 2.95 \) and \( x_2 \approx -0.042 \).[/tex]

To find the value of x that satisfies the equation [tex]\( 32x^2 - 93x - 4 = 0 \)[/tex], we can use the quadratic formula:

[tex]\[ x = \frac{{-b \pm \sqrt{{b^2 - 4ac}}}}{{2a}} \][/tex]

Where:

- a = 32

- b = -93

- c = -4

Now, let's plug these values into the quadratic formula:

[tex]\[ x = \frac{{-(-93) \pm \sqrt{{(-93)^2 - 4 \cdot 32 \cdot (-4)}}}}{{2 \cdot 32}} \]\[ x = \frac{{93 \pm \sqrt{{8649 + 512}}}}{{64}} \]\[ x = \frac{{93 \pm \sqrt{{9161}}}}{{64}} \]\[ x = \frac{{93 \pm 95.7}}{{64}} \][/tex]

Now, we have two possible solutions:

[tex]\[ x_1 = \frac{{93 + 95.7}}{{64}} \]\[ x_2 = \frac{{93 - 95.7}}{{64}} \]\[ x_1 \approx \frac{{188.7}}{{64}} \]\[ x_2 \approx \frac{{-2.7}}{{64}} \]\[ x_1 \approx 2.95 \]\[ x_2 \approx -0.042 \][/tex]

Answer:

The final amount in the account after 6 years at compound interest is $1568.78 .

Step-by-step explanation:

Given as :

The principal amount in account = p = $1500

The rate of compound interest = r = 0.75 %

The time period of the loan = t = 6 years

Let The Amount in account after 6 years = $A

From Compound Interest method

Amount = Principal × [tex](1+\dfrac{\textrm rate}{100})^{\textrm time}[/tex]

I.e A = p × [tex](1+\dfrac{\textrm r}{100})^{\textrm t}[/tex]

Or, A = $1500 × [tex](1+\dfrac{\textrm 0.75}{100})^{\textrm 6}[/tex]

Or, A = $1500 × [tex](1.0075)^{6}[/tex]

Or, A = $1500 × 1.04585

Or, A = $1568.775

So, The final amount= A = $1568.78

Hence The final amount in the account after 6 years at compound interest is $1568.78 . Answer

To complete the Venn diagram, calculate that 48 out of 60 farms grow potatoes and the remaining 16 grow sugar beets, since the potato farms number is three times the sugar beet farms.

The question asks us to complete a Venn diagram with information about how many farms grow potatoes vs sugar beets, given that 60 farms grow one or the other, not both. 4/5 of the 60 farms grow potatoes, which is 48 farms.

Since the number of farms that grow potatoes is three times the number that grow sugar beets,

we can determine the number of sugar beet farms by dividing the number of potato farms by 3, giving us 16 farms growing sugar beets.

Answer:

A) The total feet needed for the fence total perimeter is 54 feet

B) The total cost of fence is $432

C) The square feet of grass needed foe the total area is 180 square feet

D) The total cost of the project is $572

Step-by-step explanation:

Given as :

The dimension of rectangular field

Length of rectangular field = L = 12 feet

width of rectangular field = w = 15 feet

The cost of grass per square foot = 50 cents = $0.5    ( ∵ 1 cents = $0.01 )

The cost of small fence = $8 per linear foot

Now, According to question

A ) Let The total feet needed for the fence total perimeter = A feet

∵ Perimeter of rectangular field = 2 × Length + 2 × width

Or, A = 2 × L + 2 × w

Or, A = 2 × 12 feet + 2 × 15 feet

Or, A = 24 feet + 30 feet

∴ A = 54 feet

So, The total feet needed for the fence total perimeter = A = 54 feet

B ) Let The total cost of fence = $B

So, The total cost of fence = The cost of small fence × perimeter of fence

i.e B = $8 × 54 feet

∴ B = $432

So,The total cost of fence = B = $432

C) Let the square feet of grass needed foe the total area = C square feet

∵The Area of rectangular fence = Length × width

Or, The square feet of grass needed foe the total area = Area of rectangular fence = L × w

i.e C = 12 feet × 15 feet

Or, C = 180 feet²

So,The square feet of grass needed foe the total area = C = 180 square feet

D) Let The total cost of grass = $D

∵ The cost of grass per square foot = $0.5

So,Total cost of grass = $0.5 × Area of fence

i.e D = $0.5 ×  180 feet²

Or, D = $90

So, The Total cost of grass = D = $90

E) Let the total cost of the project = $E

∵Mr. Jones spend additional $50 for tools

So, The total cost of the project =  money spent on tools + total cost of fence + Total cost of grass

i.e E = $50 + B + D

Or, E = $50 + $432 + $90

∴ E = $572

So, The total cost of the project = E = $572

Hence,

A) The total feet needed for the fence total perimeter is 54 feet

B) The total cost of fence is $432

C) The square feet of grass needed foe the total area is 180 square feet

D) The total cost of the project is $572  Answer

[tex]S = P(1.08)^{t}[/tex]

Step-by-step explanation:

A $10,000 deposit at the bank will double in value in 9 years.

If the interest is r% and it is compounded each year, then we can write from the formula of compound interest that

[tex]20000 = 10000(1 + \frac{r}{100})^{9}[/tex]

⇒ [tex]2 = (1 + \frac{r}{100})^{9}[/tex]

⇒ [tex]1 + \frac{r}{100} = 1.08[/tex]

⇒ r = 8%

Therefore, the formula for the accumulated amount t years after the investment is made will be  

[tex]S = P(1 + \frac{8}{100})^{t} = P(1.08)^{t}[/tex]  

where, P is the invested principal and S is the accumulated sum. (Answer)

Answer:

Step-by-step explanation:

P = 2(L + W).....perimeter of a rectangle formula

P = 20

L = 2W + 1

20 = 2(2W + 1 + W)

20 = 2(3W + 1)

20 = 6W + 2

20 - 2 = 6W

18 = 6W

18/6 = W

3 = W <==== the width is 3 inches

L = 2W + 1

L = 2(3) + 1

L = 6 + 1

L = 7 <===== the length is 7 inches

Answer:

Width = 3 inches

Length = 7 inches

Step-by-step explanation:

L = 1 + 2W

P = 20 inches

P = 2L + 2W

2L + 2W = 20 inches

Fill in known value (length)

2(1 + 2W) + 2W = 20 inches

Solve

2 + 4W + 2W = 20 inches

6W = 18 inches

Simplify

W = 3 inches

Width = 3 inches

Length = 2(3) + 1 = 7 inches
