So, Lana gave away 26.32% of he Pokemon cards  to her little brother.

To find the percentage of cards Lana gave away, we can use the formula:(Quantity given away / Total quantity) * 100.

In this case, Lana gave away 125 cards out of her total collection of 475 cards.Plugging these values into the formula, we have:

(125 / 475) * 100 = 0.2632 * 100 = 26.32%.

Lana gave away 26.32% of her Pokemon cards to her little brother.

Alternatively, we can calculate the percentage by subtracting the remaining cards from the total and finding the ratio:

Percentage given away

= (Cards given away / Total cards) * 100

= (125 / 475) * 100

= 26.32%.

Thus, the general solution of the given differential equation `2y′ y = 5t²` is `y = Ke^(5t³/6)` where `K` is a constant of integration.

The general solution of the given differential equation `2y′ y = 5t²` and using it to determine how solutions behave as t is discussed below:Solving the differential equation:

Separating the variables of the differential equation `2y′ y = 5t²` we get:dy/y = (5/2)t² dtIntegrating both sides, we have:ln|y| = (5/6) t³ + C1

Taking the exponential of both sides, we get:y = Ke^(5t³/6) , where K = ± e^(C1) is a constant of integration.

The general solution of the given differential equation is given by `y = Ke^(5t³/6)` where `K` is a constant of integration.

How solutions behave as `t`:When `t → ∞` (i.e., as t grows large), `e^(5t³/6) → ∞`. So solutions of the given differential equation `y′ y = 5t²` grow exponentially as `t → ∞`.

When `t → -∞` (i.e., as t gets very negative), `e^(5t³/6) → 0`. So solutions of the given differential equation `y′ y = 5t²` approach `y = 0` as `t → -∞`.

Thus, the general solution of the given differential equation `2y′ y = 5t²` is `y = Ke^(5t³/6)` where `K` is a constant of integration.

Answer:

33

Step-by-step explanation:

The bottom angle is a completely straight line, and that means the angle is 180 degrees.

180 - 81 = 99

So, this means 3x = 99. We need to isolate the variable, so we have to divide everything by 3.

x = 33

Answer:

waaait i know how to do this lol ( i feel like this is correct)

x = 33

Step-by-step explanation:

so a line is 180 right?

so make the equation like this

180 = 81 + 3x

now solve for x by doing algebra

(minus both sides by 81)

3x = 99

x = 33

Step-by-step explanation

Juan has just completed a 15 kilometer race in 20 minutes.  What was his average speed in kilometers per hour?

Solution

First, 15 kilometers is a distance, so

       d  =  15

Next, we are given 20 minutes and we are asked to present the speed in kilometers per hour rather than kilometers per minute.  We need to convert 20 minutes to hours.  Since there are 60 minutes per hour, we divide by 60 to find out how many hours it took

t  =  20 minutes / 60 minutes per hour =  1/3 hours

Now we can use the d=rt equation:

15  =  (r)(1/3)

If we multiply both sides

(3)(5)  =  (r)(1/3)(3)  or  r  =  45

Juan's average speed was 45 kilometers per hour.

Answer:

16.8 inches

Step-by-step explanation:

Perimeter =2(length+width) so 2·(5.6+2.8)≈16.8

Answer and Step-by-step explanation:

First, write down what we know.

Length of Rectangle = \(5\frac{3}{5}\)

Width = \(\frac{Length}{2}\)

2 ways to solve this:

1st way:

If we convert the fraction into a decimal, then we can easily find the width.

\(5\frac{3}{5}\) can be solved by making the mixed number into a improper fraction.

Multiply the denominator (5) by the whole number (5), then add the numerator (3). This number is 28. Replace the 3 with the 28, and now we have \(\frac{28}{5}\). This number is equal to 5.6.

Now, we have to divide this number.

5.6 divided by 2 is equal to 2.8.

So, the width is equal to 2.8.

Now, we add the width and length together twice to get the perimeter of the rectangle.

2.8 + 2.8 + 5.6 + 5.6 = 16.8

So, the answer is A. 16.8 inches.

2nd way:

Since we know that the width is half of the length, we can just add the length by itself 3 times, since two of the widths combined will equal the length.

5.6 + 5.6 + 5.6 = 16.8

So, the answer is A. 16.8 inches.

Step-by-step explanation:

Answer: f(x) = mx+ b

slope = m = $25 / month

This means that for every month (x) that goes by, the total value of the stock (f(x)) will increase by $25.

y-intercept = b = $525

This is the amount of money in the account at time = 0. This will be equal to the original investment of $525.

f(x) = mx+ b = 25x + 525

Step-by-step explanation:

The volume of the figure is B. 90 cubic inches.

To determine the volume of the figure, we need to find the volume of each prism and then add them together.

The volume of Prism A is:

Volume of A = length x width x height = 2 in x 5 in x 6 in = 60 cubic inches

To find the width of Prism B, we can use the fact that it shares a side with Prism A. Since Prism A has a width of 5 inches, we know that Prism B must also have a width of 5 inches.

The volume of Prism B is:

Volume of B = length x width x height = 6 in x 5 in x 1 in = 30 cubic inches

Therefore, the total volume of the figure is:

Total Volume = Volume of A + Volume of B = 60 cubic inches + 30 cubic inches = 90 cubic inches

So the volume of the figure is 90 cubic inches.

Answer:

In 5 weeks, Ayana and Michelle have the same amount of money saved

(Namely $75)

Step-by-step explanation:

Ayana has $200 and spends $25 per week.

Michelle has $0 and saves $15 per week.

So, after one week,

Ayana has $200 - $25 = $175

Michelle has $0 + $ 15 = $15

After 2 weeks,

Ayana has $175 - $25 = $150

Michelle has $15 + $15 = $30

After 4 weeks,

Ayana has $150 - $50 = $100

Michelle has $30 + $30 = $60

After 5 weeks,

Ayana has $100 - $25 = $75

Michelle has $60 + $15 = $75

So, in 5 weeks, Ayana and Michelle have the same amount of money saved

Ayana and Michelle will have the same amount of money saved in 5 weeks.

To calculate the number of weeks Ayana and Michelle will take to have the same ammount of money, we have to make use of assumption. The reason for this is, as the number of weeks are yet to be found, so the value can only be found by substituting that particular entity into a variable.

Let's assume that number of weeks Ayana and Michelle will take to have the same ammount of money is "x".

So, Amount saved by Ayana after x weeks will be $200 - $25*x,

Amount saved by Michelle in x weeks will be $15 * x.

In the question, we have been told that Ayana and Michelle have the same amount of money saved, So we need to equate to above two equations to find the value of "x".

$200 - $25*x = $15 * x

$200 = $15 * x + $25*x

$200 = $40*x

$200 / $40 = x

x = 5

Therefore, Ayana and Michelle will take 5 weeks to have the same amound of money saved.

a. The value of θ such that f(θ) = sinθ on the interval π/2<0<π is π/2.

b. The exact value of θ such that 2/(θ) -√3 on the interval 0<θ ≤ 2π is 2/√3 radians.

c. f(θ) = g(θ) for all values of θ.

d. the results from part c) would not hold true for all values of θ.

f(θ) = sinθ
g(θ) = cotθ (1-cos 2θ)
(θ) - sin 2θ
Let's solve the given questions,
a. On the interval π/2<0<π, sinθ is positive.

Therefore,
f(θ) = sinθ
For exact value(s), we need to check for the value of θ in the interval π/2<0<π
Therefore, f(π/2) = 1
f(π) = 0
Thus, the value of θ such that f(θ) = sinθ on the interval π/2<0<π is π/2.
b.  2/(θ) -√3 = 0
=> 2/(θ) = √3
=> θ = 2/√3
Therefore, the exact value of θ such that 2/(θ) -√3 on the interval 0<θ ≤ 2π is 2/√3 radians.
c. Using trigonometric identities, analytically show that f(θ) = g(θ) for all values of θ.
Consider,
f(θ) - cos 2θ = sinθ - cos 2θ
= sinθ - (1-2sin²θ)
= 2sin²θ - sinθ - 1
Now,
g(θ) - (cosθ+ sin θ)(cosθ-sinθ)
= cotθ (1-cos 2θ) - cos²θ + sin²θ
= cos²θ/sinθ - cos²θ/sinθ - cosθ/sinθ.sinθ + sin²θ/sinθ
= (sin²θ - cos²θ)/sinθ
= sinθ - cos 2θ
Therefore, f(θ) = g(θ) for all values of θ.
d. f(π/8) = sin(π/8) = 0.382
g(π/8) = cot(π/8)(1-cos(2π/8)) = 2.613
Since f(θ) and g(θ) have different values for the same angle π/8, the results from part c) would not hold true for all values of θ.
