Brody's age is 3 years less than twice Trinity's age? The sum of their ages is 30.

Answers

Answer 1

Answer: Brody's Age is 19 and Trinity's age is 11

Step-by-step explanation:

x = Trinity's age

2x-3= Brody's age

The sum of the ages is 30, so

x + (2x-3) = 30

3x - 3 = 30

add 3 to both sides 30 turns into 33 so,

3x = 33

divide by 3 both sides

x = 11 which is trinity's age and plug x  into 2x - 3 which is 19 so that's Brody's age.

The coordinate point (-5, 18) is a point on the graph of f. Write this point in function notation.


f(-5) = 13


f(-5) = 18


f(18) = -3.6


f(18) = -5

Answers

The function notation of the coordinate point where the coordinate point is given as (-5, 18) is f(-5) = 18

What are coordinate points?

Coordinate points are mathematical statements that are used to represent the location of points on a coordinate plane

How to rewrite the function notation of the coordinate point?

The coordinate point is given as

(-5, 18)

The above coordinate point can be represented as

(x, y) = (-5, 18)

The above coordinate point can further be rewritten as

(x, f(x)) = (-5, 18)

So, we have

x = -5

f(x) = 18

Substitute x = -5 in the equation f(x) = 18

f(-5) = 18

Hence, the function notation of the coordinate point where the coordinate point is given as (-5, 18) is f(-5) = 18

Find the mean absolute deviation of this data set. What does the mean absolute deviation tell you about the dolphins at the aquarium?

Answers

The mean absolute deviation is 5.4.

The mean absolute deviation tells us that the variance of each data set is 5.4.

What is the mean absolute deviation?

The mean absolute deviation is a measure of variance that determines the average distance between each data point in the dataset and its mean.

The mean absolute deviation = 1/n ∑ l x - m(x) l

The first step is to determine the mean of the data set: (18 + 15 + 25 + 17 + 13 + 15 +  23 + 27 + 30 +  27) / 10

= 210 / 10

= 21

The second step is to determine the absolute difference between the mean and each data point. Then add the result together.

|(18 - 21) + (15 - 21)+ (25- 21) + (17- 21) + (13- 21) + (15- 21) +  (23- 21) + (27- 21) + (30- 21) +  (27- 21)| = 54

Now, divide the sum by the total numbers in the data set : 54 / 10 = 5.4

Maya is using a coordinate plane to create a map of her yard drawn to scale. Each unit
on the coordinate plane represents 1 meter. Her yard forms a quadrilateral with vertices
A(5, -3), B(10, -3), C(12, -11), and D(7, -11). Maya would like to fence in her entire
yard. Fencing costs $200 per meter. How much will it cost Maya to fence in her yard?

Answers

Answer:

$5,298.48

Step-by-step explanation:

Given vertices:

A = (5, -3)B = (10, -3)C = (12, -11)D = (7, -11)

As points A and B, and points C and D, have the same y-coordinates, AB is parallel to CD.

As there is a difference of 5 units between points A and B, and C and D, AB = CD.

As AB is parallel to CD and AB = CD ⇒ AD = BD and AD is parallel to BD.

Therefore, the quadrilateral ABCD is a parallelogram (see attachment).

To find the perimeter of ABCD, calculate the side lengths of AB and AD using the Distance Formula.

[tex]\boxed{\begin{minipage}{4.7 cm}\underline{Distance Formula}\\\\$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are the two endpoints.\end{minipage}}[/tex]

[tex]\begin{aligned}AB & =\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}\\& =\sqrt{(10-5)^2+(-3-(-3))^2}\\& =\sqrt{(5)^2+(0)^2}\\& =\sqrt{25}\\& =5\:\:\sf units\end{aligned}[/tex]

[tex]\begin{aligned}AD & =\sqrt{(x_D-x_A)^2+(y_D-y_A)^2}\\& =\sqrt{(7-5)^2+(-11-(-3))^2}\\& =\sqrt{(2)^2+(-8)^2}\\& =\sqrt{4+64}\\& =\sqrt{68}\:\:\sf units\end{aligned}[/tex]

The perimeter of a two-dimensional shape is the distance all the way around the outside.

[tex]\begin{aligned}\textsf{Perimeter of $ABCD$} & = AB + CD + AD + BC\\& = 2\:AB + 2\:AD\\& = 2 \cdot 5+2 \cdot \sqrt{68}\\& = 10+2 \sqrt{68}\\& = 10+2\sqrt{4 \cdot 17}\\& = 10+2\sqrt{4}\sqrt{17}\\& = 10+2 \cdot2\sqrt{17}\\& = 10+4\sqrt{17}\:\:\sf units\end{aligned}[/tex]

As 1 unit = 1 meter, the perimeter of the fence is (10 + 4√17) m.

If fencing costs $200 per meter:

[tex]\begin{aligned}\sf \implies Cost \:of\:fencing& = 200(10 + 4 \sqrt{17})\\& = 2000+800 \sqrt{17}\\& = 5298.4845\\ & = \$5298.48\end{aligned}[/tex]

Therefore, it will cost Maya $5,298.48 to fence her yard.

The point G(-5, -1) is reflected over the line y= -3. What are the coordinates of the resulting point, G’

Answers

The coordinates of the resulting point after the reflection are (-5, -5)

What are the coordinates of the resulting point?

When we do a reflection over a given line, the perpendicular distancee between the line and the point is invariant.

In this case, we want to reflect the point (-5, -1) over the line y = -3

The distance between the y-value of the point and the line is:

D = |-1 - (-3)| = | -1 + 3| = 2

The point is at 2 units (above) from the line, then after the reflection, the point will be 2 units below the line.

So the new y-value is:

y = -3 - D = -3 - 2 = -5

The coordinates of the resulting point are (-5, -5).

How much should Roman invest today in order to withdraw $22450.15 in exactly 3.7 years from now if interest rate is 5.65 % compounded monthly?

Answers

Roman should invest $18,223.97 in order to withdraw $22450.15 in exactly 3.7 years from now if interest rate is 5.65 % compounded monthly.

First, convert R as a percent to r as a decimal

r = R/100

r = 5.65/100

r = 0.0565 per year,

Then, solve the equation for P

P = A / (1 + r/n)^(nt)

P = 22,450.15 / (1 + 0.0565/12)^{(12)(3.7)}

P = 22,450.15 / (1 + 0.0047)(44.4)

P = $18,223.97

The principal investment required to get a total amount of $22,450.15 from compound interest at a rate of 5.65% per year compounded 12 times per year over 3.7 years is $18,223.97.

Therefore, Roman should invest $18,223.97 in order to withdraw $22450.15 in exactly 3.7 years from now if interest rate is 5.65 % compounded monthly.

adam has $800 invested in two accounts. one pays 6% annual interest and the other pays 10% interest. the amount of annual interest is the same as he would earn if the entire $800 was invested at 8.25%. How much does he have invested at each rate?

Answers

Adam invested $350 at 6% and $450 at 10%

Amount invested by Adam = $800

Interest paid by one account = 6%

Interest paid by another account = 10%

Let the amount invested in one account be x and the other be y

The formula for simple interest is given by:

Simple interest = (P*R*T)/100

where P = Principal

R = rate of interest

T = number of years amount is invested

Substituting the value in the formula we get:

Simple interest in one account = (x*6*1)/100-------(1)

Simple interest in another account = (y*10*1)/100--------(2)

The question states that interest earned would be the same when $800 is invested at 8.25%, therefore

Simple interest = (800*8.25*1)/100

= 66----(3)

Equating (1), (2) and (3) we get:

x + y = 800-----(4)

6x/100 + 10y/100 = 66

6x + 10y = 6600-----(5)

Multiplying (4) with 6 and equating it with (5)

6x + 6y = 4800

6x + 10y = 6600

4y= 1800

y = 450

x = 350

So, Adam invested $350 at 6% and $450 at 10%
