Answer:

Step-by-step explanation:

Given that "A recent survey reveals that 40% of young people between 15 and 25 years of age will buy an iPod this year. If N is the number of young people between 15 and 25"

From the given we can write

Total people between 15 and 25 age = N

Number of people who buys iPods is 40% of  N is

[tex] = \frac{40}{100}\times N[/tex]

= 0.4N

From the given we have that 35 % are enjoy  listening to Country music means  

[tex]= \frac{35}{100}\times 0.4N[/tex]

[tex]=0.35\times 0.4N[/tex]

= 0.14N

Final answer:

Calculating 35% of 40% of the young people between 15 and 25 years who will buy an iPod, the number who will enjoy listening to country music on their iPods is 0.14N, making choice (c) the correct answer.

Explanation:

To determine the number of young people between 15 and 25 years old who will enjoy listening to country music on their iPods this year, we can first calculate the number of young people who will buy an iPod. Since 40% of the group is expected to buy an iPod, this is 0.40N. Next, out of these iPod owners, 35% enjoy listening to country music. Therefore, we can find the number of iPod owners who enjoy country music by taking 35% of the 40%, which is 0.35  times 0.40N. This calculation results in 0.14N young people enjoying country music on their iPods.

This leads us to the answer choice (c) 0.14N.

Answer:

x = 3y

Step-by-step explanation:

In this question, we are asked to model an equation that clearly mimics what we have in the question using certain type of variables.

Now initially, we are told that we have 2 bunnies having 6 babies. what does this tell us?

Looking at this, we can see that the number of babies is exactly 3 times the number of bunnies. More like saying 3 times the number of bunnies equal the number of babies.

so leveraging in this finding and applying the variable, we can say each of the 2 bunnies has 3 babies per month.

Mathematically, this is same as x bunnies = 3y babies per month

Answer:

Any dimensions can make a triangle, however

this does not make a right angled triangle.

Step-by-step explanation:

Determine the length of the hypotenuse of a right angle triangle with side lengths 5ft and 9ft by using the formula:

[tex]a^2+b^2=c^2\\[/tex]

[tex]\sqrt{a^2+b^2} = c[/tex]

[tex]c=10.29[/tex]

This is not equal to 14ft.

Answer: No, those measurements cannot make a triangle

Why not? Because of the fact that the first two sides (5 and 9) add to 5+9 = 14, which is exactly as long as the third side. I recommend you using a ruler to measure out 5 inches, 9 inches and 14 inches. Mark all three as separate segments on a piece of paper. Then cut out those segments to form strips of paper with the given lengths. Then try to form a triangle. You'll find that it is impossible since the smaller segments combine perfectly to get the longest segment. Instead of a triangle, you'll only have a line segment forming.

As a rule, when you add any two sides of a triangle, they must add to something larger than the third side. The rule more formally is

For any triangle with sides a,b,c, the following three inequalities must hold true

Answer:

1 4/5 = peanuts

1 1/5 = raisins

3/5 = chocolate chips

Step-by-step explanation:

3 ÷ 1 1/4 = 2 2/5

2 2/5 × 3/4 = 1 4/5

2 2/5 × 1/2 = 1 1/5

2 2/5 × 1/4 = 3/5

To keep proportions with 3 cups of granola, Darcia would need 1 ½ cups of peanuts, 1 ¼ cups of raisins, and 3/5 cup of chocolate chips in her snack mix.

Darcia has increased her granola measurement to 3 cups, which is 2.4 times more than the original 1 ¼ cups used in the snack mix recipe (since 3 ÷ 1.25 equals 2.4). To keep the other ingredients proportional to the new quantity, we need to multiply their original amounts by the same factor of 2.4

Therefore, if she used 3 cups of granola, she would use 1 ½ cups of peanuts, 1 ¼ cups of raisins, and 3/5 cup of chocolate chips to maintain the proportions in her snack mix.

Answer:

8.2 ft

.Step-by-step explanation:

Sketch this situation.  Label the 55° angle.  The adjacent side is the distance from the stake to the bottom center of the tree.  The opposite side is the distance from the ground to the connection point of the wire on the tree.  The wire length represents the hypotenuse of this triangle.  We want to find the length of the side opposite the 55° angle.  Thus, we write

sin 55° = (opposite side)/(hypotenuse), or

(hypotenuse)(sin 55°) = (10 ft)(0.819) = 8.2 ft

Using trigonometry and the sine function, we can calculate the height of the tree as 10 ft * sin(55), which equals approximately 8.19 ft.

This problem can be solved using trigonometry, specifically the sine function. In a right triangle, the sine of an angle is defined as the length of the opposite side divided by the length of the hypotenuse. In this case, the tree forms the opposite side of our triangle, the support wire forms the hypotenuse and the angle of elevation is 55 degrees.

To express this mathematically, we can write: sin(55) = height / 10 ft. Solving this equation for height gives us: height = 10 ft * sin(55). Using a calculator, we find that sin(55) is approximately 0.81915, so the height is around 8.19 ft. Therefore, the connection point of the wire to the tree is at approximately 8.19 ft high.

Step-by-step explanation: 8 and -8

The formula to calculate the expected population of Luttrell in t years, with a 10% annual growth rate, is P = 130,457 × (1 + 0.10)^t.

To determine the total expected population, P, of Luttrell in t years, given an annual growth rate of 10%, you would use the formula for exponential growth: P = P0 × (1 + r)t, where P0 is the initial population, r is the growth rate (expressed as a decimal), and t is the number of years after the initial time. In this case, since the population in 2012 (which is our initial time) is 130,457, and the growth rate is 10% or 0.10, the equation becomes P = 130,457 × (1 + 0.10)t. This equation will calculate the expected population after t years.

Final answer:

The equation to determine the total expected population of Luttrell in t years is P = [tex]130,457 × (1 + 0.10)^t,[/tex] where P is the population and t represents the number of years after 2012.

Explanation:

To determine the total expected population, P, of Luttrell in t years, given that it is expected to grow by 10% each year, you can use an exponential growth formula. The formula incorporating this percentage growth rate and starting population in 2012 is:

P = 130,457 × (1 + 0.10)^t

Here, 130,457 is the initial population in the year 2012, 1 + 0.10 represents the growth factor (where 0.10 is the 10% growth converted to a decimal), and t is the number of years after 2012.

For example, to find the population after 1 year (t = 1), you would calculate:

P =[tex]130,457 × (1 + 0.10)^1 = 130,457 × 1.10 = 143,502.7,[/tex] which you would round to the nearest whole person.

To calculate Payne's annual contribution, multiply the annual premium by 20% and subtract that amount from the annual premium.

Explanation:

To calculate Payne's annual contribution, we need to determine 20% of the total cost of the health insurance premium and then subtract that amount from the annual premium.

Step 1: Find 20% of $6,486. Multiply $6,486 by 0.2 to get $1,297.20.

Step 2: Subtract the 20% contribution from the annual premium. $6,486 - $1,297.20 = $5,188.80.

Payne's annual contribution is $5,188.80.

Answer:

18 feet

Step-by-step explanation:

After each bounce, the ball reaches only a percentage of the maximum height it reached before.

The first height is 36 feet, after the first bounce, it will be 36*r, where r is the ratio of the height the ball can still reach by the previous maximum height.

In the second bounce, the height is 36*r^2

In the third bounce, the height is 36*r^3

In the fourth bounce, the height is 36*r^4, and this value is 2.25 ft, so:

36*r^4 = 2.25

r^4 = 2.25/36

r^4 =  0.0625

r = 0.5

So, after the first bounce, the height is:

36*r = 36*0.5 = 18 feet

The height should be 18 feet.

Given that,

Based on the above information, the calculation is as follows:

The first height is 36 feet.

Now after the first bounce, it will be 36r

Here r is the ratio of the height

In the second bounce, the height is [tex]36\times r^2[/tex]

In the third bounce, the height is [tex]36\times r^3[/tex]

In the fourth bounce, the height is [tex]36\times r^4[/tex], and this value is 2.25 ft, so:

Now

[tex]36\times r^4 = 2.25\\\\r^4 = 2.25\div 36\\\\r^4 = 0.0625[/tex]

r = 0.5

Now  

So, after the first bounce, the height is:

= 36r

= 36(0.5)

= 18 feet

Therefore we can conclude that The height should be 18 feet.

Step-by-step explanation:

A graph shows you very quickly that the maximum value of y is 1.

__

There are several ways to get there algebraically. The axis of symmetry is given for ax^2 +bx by x=-b/(2a). Here, that value is x=(-6)/(2(-1)) = 3. The maximum y-value will correspond to this x-value:

  y = -3² +6·3 -8 = -9 +18 -8 = 1

The maximum value of y is 1.

__

The axis of symmetry can also be found by factoring:

  y = -(x -4)(x -2)

It is halfway between the values of x that make these factors zero, so is ...

  x=(4+2)/2 = 3

For that value of x, we find y to be ...

  y = -(3 -4)(3 -2) = 1

__

We can also rearrange the equation to vertex form:

  y = -(x^2 -6x) -8

  = -(x^2 -6x +9) -8 -(-9)

  = -(x -3)^2 +1

The vertex is (3, 1), so the maximum value of y is 1.
