If it was asking for one can you would put 42.41 because it is (pi)(1.5)^2(6)

But then you times it by 6 cans and you get 254.47inches cubed

The total volume of juice in a six-pack, with each can being 6 inches tall and having a diameter of 3 inches, is 254.34 cubic inches. This is calculated using the volume formula for a cylinder.

The question asks for the total volume of juice in a six-pack of cans, where each can is 6 inches tall and has a diameter of 3 inches. To find the volume of one can, we use the formula for the volume of a cylinder: V = πr^2h, where V is volume, r is radius, and h is height. First, we find the radius of the can by dividing the diameter by 2, which gives us 1.5 inches. The volume of one can is therefore calculated as V = π(1.5)^2(6), which simplifies to V = π(2.25)(6) = 42.39 cubic inches. To find the total volume for a six-pack, we multiply this volume by 6: 42.39 in^3  × 6 = 254.34 in^3. Therefore, the total volume of juice in the six-pack is 254.34 cubic inches.

Answer:

Volume of larger ball = 220,781.3 cubic centimeters

Step-by-step explanation:

Let's use ratios to solve for the diameter of the larger ball first (let the diameter of larger ball be L)

[tex]\frac{LargerBall}{SmallerBall}=\frac{15}{11}=\frac{L}{55}\\11*L=15*55\\11*L=825\\L=\frac{825}{11}=75[/tex]

So, the diameter of the larger ball is 75 cm. We know radius is half of diameter, so radius of larger ball is (1/2)(75) = 37.5 cm

Ball is in the shape of a sphere, which has a formula for volume as:

[tex]V=\frac{4}{3}\pi r^3[/tex]

where V is the volume and r is the radius

now we simply plug in 37.5 into r and use 3.14 as π:

[tex]V=\frac{4}{3}\pi r^3\\V=\frac{4}{3}(3.14)(37.5)^3\\V=220,781.3[/tex]

I know its kind of confusing, it took me a while to get geometry down too.

But I hope this helps :)

Answer:

x = 15

Step-by-step explanation:

Since the triangles are similar, we can say that the ratio between the respective sides of the first triangle and the 2nd is constant.

Basically, VW / ST = VU/SR = WU/TR = k, where k is a positive real number

Solving for k is simple:

k = VU/SR = 42/21 = 2

So we found out that the 1st triangle is the 2nd triangle but scaled up 2 times.

We use this to find x.

ST * 2 = VW

x² = 4² + 5²

x² = 16 + 25

x² = 41

x = √41

Answer:

x = sqrt(41)

Step-by-step explanation:

We have a right triangle with height 5 and a base that is 1/2 of 8 = 4

We can use Pythagorean theorem

a^2 + b^2 = c^2 to find the length of the hypotenuse

5^2 + 4^2 = x^2

25+16 = x^2

41 = x^2

Take the square root of each side

sqrt(41) = x

Answer:

75 degrees

Step-by-step explanation:

The two marks on the triangle sides mean they are the same length (congruent).  Because of the Isosceles Triangle Theorem, the angles across from those two congruent sides are also congruent.  That means that angle C also measures 3x.  Because all the sides of a triangle add up to equal 180, then (x+5) + 3x + 3x = 180.  7x + 5 = 180, and 7x = 175.  That means that x = 25.  Take that 25 and sub it into 3x to get 3(25) = 75 degrees.

The simplified result is: [tex]\frac{5a^3}{3}[/tex]

Step-by-step explanation:

[tex]a^2.\frac{a^{3}+a^2b }{5a}.\frac{25}{3b+3a}[/tex]

We need to solve the above equation.

We take a^2 common from a^3+a^2b

and we take 3 common from 3b+3a

Solving,

[tex]a^2\:\frac{a^2\left(a+b\right)\:}{5a}\frac{25}{3\left(b+a\right)}[/tex]

Since a+b = b+a we can cancel them with each other.

[tex]=a^2\:\frac{a^2}{5a}\frac{25}{3}\\=a^2\:\frac{a^2}{a}\frac{5}{3}\\=a^2\:a\:\frac{5}{3}\\=\frac{5a^3}{3}[/tex]

So, The simplified result is: [tex]\frac{5a^3}{3}[/tex]

The simplified expression is (5(a + b)) / (3a(b + 1)).

To simplify the given expression, we'll perform the indicated operation step by step:

a² * [(a³ + a²b) / 5a] * [25 / (3b + 3a)]

Step 1: Cancel common factors within each fraction:

a² * [(a³ + a²b) / (5a)] * [25 / (3(b + a))]

Step 2: Simplify further:

(a³ + a²b) * [25 / (5a * 3(b + a))]

Step 3: Factor out common terms:

(a²(a + b)) * [25 / (15a(b + a))]

Step 4: Cancel common factors between numerators and denominators:

(a + b) * (25 / (15a(b + a)))

Step 5: Simplify further:

(25(a + b)) / (15a(b + a))

Step 6: Factor out common terms again:

(25(a + b)) / (15a * a(b + 1))

Step 7: Cancel common factors:

(5(a + b)) / (3a(b + 1))

So, the simplified expression is (5(a + b)) / (3a(b + 1)).

2.4 ft = height

Step-by-step explanation:

The formula for the volume of a pyramid is V = (1/3)(base area)(height).

Here V = 20 ft² = (1/3)(base area)(height).

Since the base area is (5 ft)², or 25 ft²,   20 ft² = (1/3)(25 ft²)(height),

The rule of reflection for the triangle is Ry ( x , y ) → ( -x , y )

Reflection is a type of transformation that flips a shape along a line of reflection, also known as a mirror line, such that each point is at the same distance from the mirror line as its mirrored point. The line of reflection is the line that a figure is reflected over. If a point is on the line of reflection then the image is the same as the pre-image. Images are always congruent to pre-images.

The reflection of point (x, y) across the x-axis is (x, -y). When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

Given data ,

Let the triangle be represented as ΔMLN

Now , the coordinates of the triangle are

The coordinate of M = M ( -5 , 4 )

The coordinate of L = L ( -6 , 2 )

The coordinate of N = N ( -3 , 2 )

when the triangle is reflected across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse.

The reflection of point (x, y) across the y-axis is (-x, y).

So , the coordinate of M' = M' ( 5 , 4 )

The coordinate of L' = L' ( 6 , 2 )

The coordinate of N' = N' ( 3 , 2 )

Hence , the rule of reflection is Ry ( x , y ) → ( -x , y )

Answer:

Step-by-step explanation:

This is a geometric sequence. The general formula for any term is

t_n = a*r^(n-1)

t1 = 3

r = 3

t_n = 3* 3^(n - 1)

t_4 should be 81

t_4 = 3*3^(n - 1)

t_4 = 3*3^3

t_4 = 3 * 27

t_4 = 81

Answer:

an = 3 * (3)^ (n-1)  or

an = 3^n

Step-by-step explanation:

To find the common ratio, take the second term and divide by the first term

9/3 = 3

To verify take the third term and divide by the second

27/9 =3

Since this is a geometric sequence, it is of the form

an = a1*r^(n-1)  where a1 is the first term and r is the common ration

an = 3 * (3)^ (n-1)

Since the first term is the same as the term inside the parentheses, we can combine

an = 3^1 * 3 ^ (n-1)

   = 3^ (1+n-1)

  = 3^ (n)

The formula to calculate continuously compounded interest is equal to

[tex]A=P(e)^{rt}[/tex]  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest in decimal  

t is Number of Time Periods  

e is the mathematical constant number

we have  

[tex]t=15\ years\\ P=\$1,000\\ r=0.0725[/tex]  

substitute in the formula above  

[tex]A=\$1,000(e)^{0.0725*15}=\$2,966.85[/tex]  

Final answer:

The total amount for a $1000 investment at 7.25% compounded continuously for 15 years is approximately $2972.70, demonstrating the power of compound interest.

Explanation:

To calculate the total amount from an investment that is compounded continuously, you use the formula for continuous compounding, which is A = Pert, where A is the amount of money accumulated after n years, including interest, P is the principal amount (the initial sum of money), r is the annual interest rate (decimal), t is the time the money is invested for, and e is the base of the natural logarithm, approximately equal to 2.71828.

Substituting our values into this formula we get:
A = 1000 * e0.0725*15
A ≈ 1000 * e1.0875
A ≈ 1000 * 2.9727
A ≈ $2972.70

This result shows us the power of compound interest and highlights starting to save money early in life as a key financial decision.

Saving account: A = 500(1 + 0.023t)

CD account: A = 500(1 + 0.018/12)^(12t)

Future value of saving account is $730

Future value of CD account is $716.47

She should choose the saving account

Step-by-step explanation:

* Lets revise the rules of simple and compound interest

- Simple Interest Equation (Principal + Interest)

 A = P(1 + rt)

- Where:

• A = Total amount (principal + interest)  future amount

• P = Principal Amount

• I = Interest Amount

• r = Rate of Interest per year in decimal; r = R/100

• t = Time Period involved  

- Compound interest can be calculated using the formula

 A = P (1 + r/n)^(nt)

Where:

• A = the future value of the investment, including interest

• P = the principal investment amount (the initial amount)

• r = the annual interest rate (decimal)

• n = the number of times that interest is compounded per unit t

• t = the time the money is invested for

* Now lets solve the problem

- Saving account:

# P = $500

# r = 2.3/100 = 0.023

# t = t

∴ A = 500(1 + 0.023t) ⇒ (1)

- CD account:

# P = $500

# r = 1.8/100 = 0.018

# n = 12

# t = t

∴ A = 500(1 + 0.018/12)^(12t) ⇒ (2)

* In case t = 20 years

- In equation (1)

# A = 500(1 + 0.023 × 20) = $730

- In equation (2)

# A = 500(1 + 0.018/12)^(12 × 20) = $716.47

* The future value of saving account is greater than the CD account

∴ She should choose the saving account

Answer:

Step-by-step explanation:

A shift along the x-axis is the opposite in the graph than in the equation. Rather than the x-intercept(s) being negative if the equation is x - n, they become positive; likewise for the other way around. A is the only answer that follows this rule. However, the y-intercept is y = n, so if n is negative, y gets shifted down rather than up.

30,360ft÷5,280=5.75miles

5,280 is how many ft are in a mile.:)

so no,Morgan wasn't over 6 miles

To determine if Morgan was over 6 miles above the ground, we must convert the altitude from feet to miles by dividing by 5,280 (the number of feet in a mile). This computation shows us that Morgan was indeed over 6 miles high.

Yes, Morgan was over 6 miles above the ground. In order to solve this problem, we need to know that 1 mile equals 5,280 feet. Thus, first, we have to convert the altitude in feet into miles. We do this by dividing the number of feet by the number of feet in a mile.

30,360 feet / 5,280 feet per mile = 5.75 miles

Hence, Morgan was indeed flying at an altitude greater than 6 miles above the ground.

The answer is:

The total time traveled  by the cabin cruiser is equal to 9 hours.

To solve the problem, we need to write two equations using the given information about the travel upstream and downstream.

Then, we need to write two equations:

Let be "x" the speed of the cabin cruiser (12 mph in still water)

Let be "y" the speed of the current (4 mph).

So,

For the travel against the current (upstream), we have:

[tex](x-y)*t_{upstream}=48miles\\\\(x-y)*t_{upstream}=48miles\\\\(x-4mph)*t_{upstream}=48miles[/tex]

For the travel with the current (downstream), we have:

[tex](x+y)*t_{downstream}=48miles\\\\(x+y)*t_{downstream}=48miles\\\\(x+4mph)*t_{downstream}=48miles[/tex]

Also, we know from the statement that the speed of the cabin cruise traveling in still water is equal to 12mph.

So,

Calculating the time traveled upstream, we have:

[tex](x-4mph)*t_{upstream}=48miles(12mph-4mph)*t_{upstream}=48miles(8mph)*t_{upstream}=48milest_{upstream}=\frac{48miles}{8mph}=6hours[/tex]

Calculating the time traveled downstream, we have:

[tex](x+4mph)*t_{downstream}=48miles(12mph+4mph)*t_{downstream}=48miles(16mph)*t_{downstream}=48milest_{downstream}=\frac{48miles}{16mph}=3hours[/tex]

Now that we know the time traveled upstream and downstream, we need to calculate the total time traveled using the following equation:

[tex]TotalTime=t_{upstream}+t_{downstream}\\\\TotalTime=6hours+3hours=9hours[/tex]

Therefore we have that the total time traveled is equal to 9 hours.
