9) The function f(n) = 5n represents the number of candles needed for n tables. How many candles are
needed for 15 tables?​

I think the answer is 90 degrees because both triangles are 90, but you're only finding KN and KL which is on ONE triangle not both. SO there's a 90 degree angle on the top triangle. So I'd go with 90, but I could be wrong.

Answer:

The rate of interest paid on the principal amount is 8%.

Step-by-step explanation:

Here, Principal Amount = $2,000

Time = 3 months = (3/ 12 ) Years = 0.25 years

Rate = R

Interest Amount  = $40

Now, as we know :

Simple Interest  = [tex]\frac{P \times R \times T}{100}[/tex]

⇒[tex]40  = \frac{2,000 \times R \times 0.25}{100}\\\implies R = \frac{40 \times 100}{2000 \times 0.25}   =8[/tex]

or, R = 8%

Hence, the rate of interest paid is 8%.

Answer:

3.0 grams of the element are left after 18 minutes

Step-by-step explanation:

Recall that an exponential decay that can be studied with the following formula for the amount of material (A) as a function of time (t):

[tex]A(t)=A_0(1-r)^t[/tex]

where:

[tex]A_0[/tex] is the starting amount of the substance (in our case 820 grams)

r is the rate of decay (which in our case given as 26.8% can be written in decimal form as 0.268

and t is the time in minutes (in our case t = 18 minutes)

Then we have:

[tex]A(t)=A_0(1-r)^t\\A(18)=820*(1-0.268)^18\\A(18)=820*(0.732)^18\\\\A(18)=2.985\,grams[/tex]

which can be rounded to 3.0 grams

Answer: 3.0

Step-by-step explanation:

a=820

r= rate= 26.8%=0.268

b=1-r=1-0.268=0.732

y=820(0.732)^18

y=2.985474

Answer:

237.375 ft³

Step-by-step explanation:

Given:

Side length of bigger cube is, [tex]S_1=8\ ft[/tex]

Side length of smaller cube is, [tex]S_2=6.5\ ft[/tex]

Now, volume of the bigger storage unit is given as:

[tex]V_1=S_1^3\\V_1=S_1\times S_1\times S_1\\V_1=8\times 8\times 8=512\ ft^3[/tex]

Volume of the smaller storage unit is given as:

[tex]V_2=S_2^3\\V_2=S_2\times S_2\times S_2\\V_2=6.5\times 6.5\times 6.5=274.625\ ft^3[/tex]

Now, difference in the volume of the two storage units is given as:

[tex]V_1-V_2=512-274.625=237.375\ ft^3[/tex]

Therefore, the difference in their volumes is 237.375 ft³.

To find the difference in volume between two cube-shaped storage units, determine the length of one side for each cube, calculate their volumes with the formula 'Volume = side length cubed', and subtract one volume from the other.

To calculate the difference in volume between the two cube-shaped storage units, follow these steps:

For example, let's assume the side length of cube 1 is 2 meters and the side length of cube 2 is 3 meters. The volume of cube 1 will be 2^3 or 8 m³ and the volume of cube 2 will be 3^3 or 27 m³. The difference in volume between the two cubes would be 27 m³ - 8 m³ = 19 m³.

Ages of Mark, Brett and Carl are 80 years, 60 years and 70 years respectively.

Solution:

Given that

Brett is 18 years younger than Mark.

Carl is 10 years younger than Mark.

The sum of the ages of Brett, Mark, and Carl is 212

Need to determine age of Brett, Mark, and Carl.

Let assume age of mark in years be represented by variable x

As it is given that Brett is 18 years younger than Mark , so if we subtract 18 from the age of Mark we will get age of Brett ,

=> Age of Brett = x – 18

Also given that Carl is 10 years younger than Mark , so if we subtract 10 from the age of Mark we will get age of Carl ,

=> Age of Carl = x – 10

Given sum of ages of Brett, Mark, and Carl is 212

=> Age of Mark + Age of Brett + Age of Carl = 212

=> x + ( x – 18 ) + ( x – 10) = 212

=> 3x – 28 = 212

=> 3x = 212 + 28

Age of Mark = x = 80 years

Age of Brett = x – 18 = 80 – 18 = 62 years

Age of Carl = x – 10 = 80 – 10 = 70 years

Hence Ages of Mark , Brett and Carl are 80 years, 60 years and 70 years respectively.

Step-by-step explanation:

Using the given points, solve for a, h, k in  g(x) = [tex]a(x - h)^2[/tex] + k . The function rule is  g(x) = [tex]a(x - h)^2[/tex] + k .

To find the function rule for g(x), which is a translation of the quadratic function[tex]\( f(x) = x^2 \)[/tex], we need to determine the horizontal and vertical shifts based on the given points on the graph. The general form for a translated quadratic function is [tex]\( g(x) = a(x - h)^2 + k \)[/tex], where (h, k) represents the vertex of the parabola.

Let's use the given points (9,10), (5,10), and (7,6) to find the translation values.

1. Vertex Form of Quadratic Function:

The vertex form of a quadratic function is [tex]\( f(x) = a(x - h)^2 + k \)[/tex], where (h, k) is the vertex. Let's find the vertex using the given points.

For (9,10):

[tex]\[ 10 = a(9 - h)^2 + k \][/tex]

For (5,10):

[tex]\[ 10 = a(5 - h)^2 + k \][/tex]

For (7,6):

[tex]\[ 6 = a(7 - h)^2 + k \][/tex]

2. Solve the System of Equations:

Solve the system of equations to find the values of  a ,  h , and  k .

3. Substitute into Vertex Form:

Once you find the values of  a ,  h , and  k , substitute them into the vertex form g(x) = [tex]a(x - h)^2[/tex] + k.

By following these steps, you'll obtain the function rule for g(x), which is a translation of  [tex]f(x) = x^2[/tex]  based on the given points on the graph.

To make the most 'appley' juice, use a mixture with a high percentage of pure apple juice and minimal amounts of other ingredients.

Explanation:

To make the most "appley" juice, you would want to use a mixture that has a high concentration of apple juice. In this case, the best choice would be a mixture with a high percentage of pure apple juice and minimal amounts of other ingredients. This would ensure that the flavor of the juice is predominantly apple.

For example, a mixture with 90% apple juice and 10% other fruit juices would have a strong apple flavor. On the other hand, a mixture with 50% apple juice and 50% other fruit juices would have a less pronounced apple taste.

By experimenting with different ratios of apple juice to other ingredients, you can find the mixture that results in the most "appley" juice.
