(d) Sandy’s gross annual income is $51,350. She is paid biweekly and has 5% deducted from her paycheck for her 403(b). Her employer matches her deduction, up to 4%. How much is deposited into Sandy’s 403(b) each payday?
Based on the annual income, the payment period, and the amount deducted for the 403(b), the amount deposited into Sandy's 403(b) is $220.
How much is deposited into Sandy's 403(b)?First find the biweekly income:
= 51,350 / (52 weeks / 2 )
= 51,350 / 21 weeks
= $2,445.24
5% is deducted from her wages and the employer matches 4% of the salary. The amount deposited is:
= (5% + 4%) x 2,445.24
= $220

The length of one of the sides of a regular hexagon is 7.8cm, find the perimeter of this polygon
Answer:
46.8 cm
Step-by-step explanation:
A hexagon has six sides. If it is a regular hexagon, then it is equilateral, meaning that each side is the same length. If one side is 7.8cm, then all sides will be 7.8cm. You can find the perimeter by adding 7.8 six times, or multiplying 7.8 by six.
7.8 · 6 = 46.8

What is an equation of the line perpendicular to 5x−4y=10 that passes through the point (−1,−6) ?
Answer:
y = -4/5x-34/5
Step-by-step explanation:
1. Put into slope-intercept form: 5x-4y = 10 ⇒ 4y = 5x-10 ⇒ y = 5/4x - 5/2
2. A perpendicular slope is the negative reciprocal of the original slope. ⇒ m = -4/5
3. Make a general solution using the new slope: y = -4/5x + b
4. Plug in the point (-1,-6) and solve for b: -6 = -4/5(-1) + b ⇒ -6-(4/5) = b ⇒
b = -34/5
5. Put b in the general solution to find the particular solution: y = -4/5x-34/5

How can you find a unit rate from a graph?
Answer:
To find the unit rate, divide the numerator and denominator of the given rate by the denominator of the given rate. So in this case, divide the numerator and denominator of 70/5 by 5, to get 14/1, or 14 students per class, which is the unit rate.
Also, what are unit rates? A rate is a special ratio in which the two terms are in different units. For example, if a 12-ounce can of corn costs 69¢, the rate is 69¢ for 12 ounces. When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates.

01. Se tienen los angulos consecutivos AOB, BOC y COD. se cumple m& AOC=125° m
La diferencia entre los ángulos AOB y COD del sistema de tres ángulos consecutivos es igual a 25°.
La medida del ángulo BOC pertenenciente al sistema de tres ángulos consecutivos es igual a 20°.
Cómo analizar tres ángulos consecutivos
Por la geometría Euclídea conocemos que un conjunto de ángulos cuando comparten entre cada par de ángulos vecinos comparten el mismo vértice y la misma semirrecta.
De acuerdo con el enunciado, tenemos las siguientes condiciones:
∠AOB + ∠BOC = 125° (1)
∠BOC + ∠COD = 100° (2)
Por (1) y (2) tenemos las siguiente identidad:
∠AOB - 25° = ∠COD
∠AOB - ∠COD = 25°
La diferencia entre los ángulos AOB y COD del sistema de tres ángulos consecutivos es igual a 25°. [tex]\blacksquare[/tex]
En el segundo caso, tenemos el siguiente sistema:
∠AOB = ∠BOC + ∠COD (3)
∠AOB + ∠BOC - ∠COD = 40° (4)
Por (3) y (4) tenemos la siguiente identidad:
2 · ∠BOC = 40°
∠BOC = 20°
La medida del ángulo BOC pertenenciente al sistema de tres ángulos consecutivos es igual a 20°. [tex]\blacksquare[/tex]

A ball is thrown from an initial height of 3 feet with an initial upward velocity of 28 ft/s. The ball's height h (in feet) after 1 seconds is given by the following:
h = 3 +28t-16t^2

The value of t at a height of 11 feet is 0.36 sec when the ball is going upwards and 1.39 seconds when the ball is coming downwards.
What is a quadratic equation?A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers.
It is written in the form of ax²+bx+c.
Given that the height of the ball at time t is given by the function,
[tex]h(t) = 3+ 28t -16t^2[/tex]
where t is in seconds and h is in feet.
Now, the height of the ball is given to be 11 feet, therefore, substituting the value of h in the function as 11,
[tex]h(t) = 3+ 28t -16t^2\\\\11 = 3+ 28t -16t^2\\\\-16t^2 + 28t +3 -11 = 0\\\\-16t^2 + 28t -8 = 0[/tex]
Now, solving the given quadratic equation, we will get,
[tex]x= \dfrac{-b\pm \sqrt{b^2-4ac}}{2a}\\\\t = \dfrac{-(28)\pm \sqrt{(28)^2-4(-16)(-8)}}{2(-16)}\\\\t= 0.36\ or\ 1.39[/tex]
Hence, the value of t at a height of 11 feet is 0.36 sec when the ball is going upwards and 1.39 seconds when the ball is coming downwards.

Matthew collected data about the ages of the actors in two different community theater groups. He drew a box plot for one of the sets of data and made a table of the other set of data.Ages of Actors is the Southside Players
For the Northside players, the median is 36, the range is 32 and the IQR is 18. For the southside Players : the median is 26, the range is 12 and the IQR is 12.
What is median?The median is regarded as the middle number among a series of sorted numbers that are placed in ascending or descending order.
Note that from the image attached, the northside ages are 22, 25, 28, 29, 29, 36, 36, 41, 49, 49, 54.
The median northside ages therefore is 36
For Range = Highest number - Lowest number
54-22 = 32
IQR = Q₃ - Q₁
Note that first quartile Q1 is said to be the median of the n lowest values and third quartile Q3 is the median of the n highest values.
Lowest value is 22 + 25/2 = 28.5.
Highest value is 49 + 44/ 2= 46.5.
Therefore, IQR = Q₃ - Q₁
46.5 - 28.5 =
IQR = 36
Note, for Southside Players;
If the Ages of Actors is the Southside Players are 20 22 24 26 28 30 32 34.
Then the median is = 26
Range is = 34-22 = 12
IQR = Q₃ - Q₁
Lowest = 20 + 22/ 2 = 21
Highest is 32 + 34 / 2 = 33
33 - 21
IQR = 12
Therefore, for the Northside players, the median is 36, the range is 32 and the IQR is 18. For the southside Players : the median is 26, the range is 12 and the IQR is 12.

What is 0.75 written as a fraction?
Solution:
0.75 = Decimal
Rewriting the decimal number as a fraction with 1 in the denominator

As we know that the sum of all three angles of a triangle is 180°.
If ∆ABC is right angled at C
C = 90°

=> [tex]\:\sf{∠A\: +\:∠B\: +\: 90°\:=\:180°}[/tex]
