a) Net result of Tamiko's transactions = $143.75

b) Total amount she can save = $86.25

Step-by-step explanation:

Step 1 :

Given,

Amount Tamiko got in her first check =  $109.60

Amount of the bonus check = $34.15

Fraction of the amount she wants to save = [tex]\frac{3}{5}[/tex]

We need to find the net results of her transactions and the amount she will save

Step 2 :

The new result of her transactions can be computed by adding the amount she has received through both the check.

Total amount she received  = 109.60 + 34.15 = 143.75

Total amount she can save =   [tex]\frac{3}{5}[/tex] × 143.75 = 86.25

Step 3 :

Answer :

a) Net result of Tamiko's transactions = $143.75

b) Total amount she can save = $86.25

Step-by-step explanation:

[tex]5 \: hours \: = 5 \times 60 = 300 \: min \\ minutes \: per \: episode = \frac{300}{6} \\ = 50 \\ [/tex]

Hence, each episode lasted for 50 minutes on an average.

On average, each episode of the TV series lasts 50 minutes, calculated by converting the total viewing time of five hours to 300 minutes and dividing that by the number of episodes, which is six.

To calculate the average duration of an episode, we need to convert the total time of all episodes from hours to minutes and then divide by the number of episodes.

There are 60 minutes in one hour, so five hours equates to 300 minutes (5 hours × 60 minutes/hour = 300 minutes). With six episodes in total, we divide the total minutes by the number of episodes to find the average length of one episode.

300 minutes / 6 episodes = 50 minutes per episode.

Therefore, on average, each episode of the TV series lasts 50 minutes.

Answer:

AB = [tex]4\sqrt{3}[/tex]

Step-by-step explanation:

30-60-90 theorem, usually x is used to explain but I will use y since x is in your problem, just substitute any variable for y

in a 30 -60 -90 triangle

the length opposite the 30 degrees is y

the length opposite the 60 degrees is y[tex]\sqrt{3}[/tex]

the length opposite the 90 degrees is 2y

since y[tex]\sqrt{3}[/tex] = 6

y = 6/[tex]\sqrt{3}[/tex]

rationalizing the denominator

[tex]\frac{6}{\sqrt{3} } *\frac{\sqrt{3}}{\sqrt{3}}[/tex] = [tex]\frac{6\sqrt{3} }{3} = 2\sqrt{3}[/tex]

if y = [tex]2\sqrt{3}[/tex], 2y = [tex]4\sqrt{3}[/tex]

Answer: B) 1 second

Step-by-step explanation:

plug 16 (final height) into the equation given:

16=-16t^2+8t+24, and solve for t.

x will equal -1/2 or 1

disregard the negative because you can’t have time.

To reach 16 feet above the water, you would reach that height after approximately 1/2 second. Option C

To find when you would reach 16 feet above the water, set the function h(t) equal to 16 and solve for t:

-16t2 + 8t + 24 = 16

Combine like terms to get:

-16t2 + 8t + 8 = 0

Now, you can use the quadratic formula to solve for t:

t = (-b ± √(b2 - 4ac)) / (2a)

Plug in the values of a, b, and c from the equation:

t = (-8 ± √(82 - 4(-16)(8))) / (2(-16))

Simplify the expression inside the square root and solve for t to get the answer:

t ≈ 1/2 second

Option C

Answer:

m=3/4

Step-by-step explanation:

Slope is equal to the change in y over the change in x, or rise over run.

m=change in y/change in x

The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).

m=y2−y1/x2−x1

Substitute in the values of x and y into the equation to find the slope.

m=9−(3)/5−(−3)

Simplify.

m=3/4

The slope of the line passing through the points (-3,3) and (5,9) is 3/4

The formula for calculating the slope of a line is expressed as:

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\[/tex]

Given the coordinate (-3,3) and (5,9), substitute the coordinates into the formula as shown below;

∠ M + ∠N = 180 {supplementary}

5x+18 + 3x + 2 = 180    {Now add the like terms}

8x + 20 = 180

        8x = 180 - 20

        8x = 160

          x = 160/8

         x = 20

∠M = 5x + 18 = 5*20 + 18 = 100 + 18 = 118

We have to find the constant of proportionality in the equation

We know that,

When y varies directly with x, then

[tex]y \propto x\\\\y = kx ---- eqn\ 1[/tex]

Where, "k" is constant of proportionality

From given,

y = 4.50x

Compare the above equation with eqn 1,

Answer: x = -14/5

Step-by-step explanation: We shall begin by expanding the brackets for both sides of the equation

-2/3 (x + 2) = 1/6 (x + 6)

(-2x/3) -4/3 = (x/6) + 1

By collecting like terms we now have

(-2x/3) - (x/6) = 1 + 4/3

(-4x - x)/6 = 7/3

-5x/6 = 7/3

By cross multiplication we now have

-5x (3) = 7 (6)

-15x = 42

x = -(42/15) {simplify further by dividing the RHS by 3}

x = -14/5

Therefore x equals, minus fourteen over five (-14/5)

Step-by-step explanation:

The cone is sliced by a plane, which produces a smaller cone on top.  This cone is similar to the original cone.  Therefore:

R / H = r / h

2 / 8 = r / 4

r = 1

The radius of the circle at the intersection of the plane and the cone is 1.

To find the radius of the circle at the intersection of the plane and the cone, we start by understanding the geometry of the cone and the slicing plane.

Given:

- Cone height ( h = 8 )

- Cone radius ( r = 2 )

- The plane slices the cone halfway along its height, so the distance from the vertex to the plane is  [tex]\( \frac{8}{2} = 4 \)[/tex].

Let's denote:

- ( R ): Radius of the circle at the intersection of the plane and the cone.

At height ( h ) from the vertex of the cone, the radius ( R ) of the circle formed by the intersection with the plane is related to the similar triangles formed by the cone and the slice plane.

The ratio of corresponding sides of similar triangles gives us:

[tex]\[ \frac{R}{r} = \frac{h - 4}{h} \][/tex]

Substitute the given values:

[tex]\[ \frac{R}{2} = \frac{8 - 4}{8} = \frac{4}{8} = \frac{1}{2} \][/tex]

Now, solve for ( R ):

[tex]\[ R = 2 \cdot \frac{1}{2} = 1 \][/tex]

Therefore, the radius of the circle at the intersection of the plane and the cone is [tex]\( \boxed{1} \).[/tex]

Answer:

The correct answer is B. $ 29,555.50

Step-by-step explanation:

Let's calculate A, using the formula provided, this way:

A = P * [(1 + r)ⁿ - 1]/r * (1 + r)ⁿ, where:

P is the month payment = 725

r is the monthly interest rate = 0.0825/12 = 0.006875

n is  the the number of months to pay = 4 * 12 = 48

Replacing with the values we know, we have:

A = P * [(1 + r)ⁿ - 1]/r * (1 + r)ⁿ

A = 725 * [(1 +0.006875 )⁴⁸ - 1]/0.006875 * (1 +0.006875 )⁴⁸

A = 725 * 0.38939833/0.006875 * 1.38939833

A = 282.313789/0.009552114

A = 29,555.50

The correct answer is B. $ 29,555.50

The correct option is B. [tex]\$29555.50[/tex]. The maximum loan Chase can afford, while making monthly payments of [tex]\$725[/tex] for [tex]4[/tex] years at an [tex]8.25\%[/tex] annual interest rate.

Given:

Monthly payment [tex]\( P = $725 \)[/tex]

Annual interest rate [tex]\( r = 8.25\% \)[/tex] or [tex]\( 0.0825 \)[/tex] as a decimal

Number of payments per year [tex]\( n = 12 \)[/tex] (since monthly payments)

Number of years [tex]\( t = 4 \)[/tex]

The formula to calculate the present value [tex]\( A \)[/tex] of the loan is:

[tex]\[ A = P \times \frac{1 - (1 + \frac{r}{n})^{-nt}}{\frac{r}{n}} \][/tex]

Now, substitute the given values

[tex]\[ A = 725 \times \frac{1 - (1 + \frac{0.0825}{12})^{-12 \times 4}}{\frac{0.0825}{12}} \][/tex]

First, calculate [tex]\( \frac{r}{n} \)[/tex]

[tex]\[ \frac{0.0825}{12} = 0.006875 \][/tex]

Next, calculate [tex]\( (1 + \frac{r}{n})^{-nt} \)[/tex]

[tex]\[ (1 + 0.006875)^{-48} = 0.7221 \][/tex]

Now substitute these values into the formula for [tex]\( A \)[/tex]

[tex]\[ A = 725 \times \frac{1 - 0.7221}{0.006875} \][/tex]

[tex]\[ A = 725 \times \frac{0.2779}{0.006875} \][/tex]

[tex]\[ A = 725 \times 40.4218 \][/tex]

[tex]\[ A = 29555.50 \][/tex]

The width of the rectangle, given its perimeter and length, is calculated using the formula for the perimeter of a rectangle. By reorganizing the terms and isolating the width, we find that the width is 4x + 3/2y, which is Answer Choice A.

The perimeter of a rectangle is given as 15x + 17y. The length is provided as 7/2x + 7y. To find the width, we need to remember that the perimeter of a rectangle is twice the sum of its length and width (P = 2l + 2w). Let's denote the width of the rectangle as 'w'.

So, the equation representing the perimeter is:

15x + 17y = 2(7/2x + 7y) + 2w

Now let's multiply out the factors on the right side:

15x + 17y = 2(7/2x) + 2(7y) + 2w

15x + 17y = 7x + 14y + 2w

To find 'w', we need to move all terms involving 'w' to one side of the equation and all other terms to the other side:

2w = 15x + 17y - (7x + 14y)

2w = 15x - 7x + 17y - 14y

2w = 8x + 3y

Divide throughout by 2 to find 'w':

w = 4x + 3/2y

The width of the rectangle is 4x + 3/2y, which corresponds to Answer Choice A.

To calculate the total cost for a 660 feet fence by Company 2, subtract the initial 550 feet covered by the flat fee from the total length, multiply the additional feet by the per-foot cost, and add the flat fee to get the final cost, which is $7790.

The student is asking about calculating the total cost for installing fencing, which involves initial fees and additional per unit costs. In this case, Company 2 charges a flat fee for the first 550 feet of fence and then an additional fee for each foot beyond that.

To find the total cost when Company 2 installs a fence of 660 feet, we first calculate the number of feet beyond the initial 550 feet. This is 660 - 550 = 110 feet. Then, we multiply the additional feet by the cost per additional foot: 110 feet x $29/foot = $3190.

Lastly, we add the initial flat fee of $4600 to the cost for the additional feet to get the total cost: $4600 + $3190 = $7790.
