For the month of December, a checking account has a balance of $500 for 12 days, $1250 for 12 days, $1150 for 3 days, and $600 for 4 days. What is the average balance for December?

Answers

Answer:

$866.13

Step-by-step explanation:

to get an average, you add up all the factors then divide them by how many there are. I added 500 12 times to 1250 12 times to 1150 3 times and 600 4 times.

aka (500*12)+(1250*12)+1150+1150+1150+600+600+600

then i divided by 31 because 12+12+3+4=31. giving the average $866.13.

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.

Mayerlin wants to ride her bicycle 56 miles this week. She has already ridden 8 miles.

Please help!

Answers

if in the next 6 days she rides an average of 8 miles per day, she will meet her goal.

What is the average number of miles she would have to ride each day to meet her goal?

We know that Mayerlin wants to ride her bicycle for 56 miles this week, and she already has ridden 8 miles, so the distance left is:

56mi - 8mi = 48mi

Now, to find the average distance that she needs to ride each day in order to meet her goal, we need to take the quotient between the distance left and the number days that she has left (6 days), then we will get:

D = 48mi/6 = 8mi

This means that if in the next 6 days she rides an average of 8 miles per day, she will meet her goal.

Applying the vertical angles theorem and the linear pair theorem, the measure of angle PQV is calculated as: 53°.

How to Apply the Linear Pair Theorem?

The linear pair theorem states that when two angles form a linear pair, the sum of both angles of the linear pair would be equal to 180 degrees.

What is the Vertical Angles Theorem?

Two angles that are a vertical pair, have a measure that is equal to each other, based on the vertical angles theorem. That is, they are congruent angles.

m<RQS + m<PQT = 180 degrees [linear pair theorem]

Substitute

(2m + 4)° + (3m + 1)° = 180°

Solve of the value of m

2m + 4 + 3m + 1 = 180

Add like terms together

2m + 3m + 4 + 1 = 180

5m + 5 = 180

5m + 5 - 5 = 180 - 5

5m = 175

5m/5 = 175/5

m = 35

m<PQR = 3m + 1 [vertical angles theorem]

Plug in the value of m

m<PQR = 3(35) + 1

m<PQR = 105 + 1

m<PQR = 106°

m<PQV = 1/2(m<PQR)

m<PQV = 1/2(106)

m<PQV = 53°

Thus, applying the vertical angles theorem and the linear pair theorem, the measure of angle PQV is calculated as: 53°.
