Peter is 19 years old. He lives at home with his parents and goes to college part time. He recently started working as a server, working 40 hours per week.
Where Peter lives, the minimum wage for tipped and non tipped employees is $7.25 per hour.
In the average week, he serves 90 tables whose typical bill is $21 with an average tip of 15%.
How much money does he make in a typical week??
Answer: $573.50
Step-by-step explanation:
40hrs x $7.25 per hour= $290 per week$21 x 0.15 = $3.15$3.15 x 90 tables per week = $283.50$283.50 + $290 = $573.50can someone help me please?? :))

How I got that answer:
The interval 0 < t < 30 has the midpoint of 15 since (0+30)/2 = 15
The interval 30 < t < 60 has the midpoint 45 because (30+60)/2 = 45
We add up the endpoints and then divide by 2 to get the midpoint.
Repeat this for each of the intervals mentioned.
From top to bottom, the midpoints are:
154575105Notice we add 30 to each midpoint to get the next one. This is directly due to the fact that each interval is 30 units wide (eg: 90-60 = 30).
Multiply each midpoint by the corresponding frequency for a given row.
15*7 = 10545*27 = 121575*12 = 900105*4 = 420Then add up those products.
105+1215+900+420 = 2640
Lastly, we divide this over the sum of the frequencies 7+27+12+4 = 50 to get 2640/50 = 52.8
The average time spent on homework is estimated to be about 52.8 minutes
Note that the majority of the the students (27) are in the 30 < t < 60 interval, so the mean of 52.8 fits this interval perfectly. It's closer to the right endpoint of the interval due to the fact the other 12+4 = 16 students are above this, and they make up the second most majority compared to the 27.
The reason why 52.8 is an estimate rather than the actual mean is because we are estimating each interval by picking out the midpoint each time. The midpoint is at the direct center, so it's the best guess we can do.
A square garden plot has an area of 24 ft2. Find the length of each side in simplest radical form. Calculate the length of each side to the nearest tenth of a foot.
Answer:
4.9 ft
Step-by-step explanation:
Area of square = side squared
S² = A
Sub in 24 for A, then take square root of each side to find S.
S² = 24
S = sqrt (24)
= sqrt (4×6) - factorize
= 2(sqrt (6)) ft
≈ 4.9 ft

Answer:
option 1 is correct
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
Find all values of 1 for which the ball's height is 11 feet.
Round your answer(s) to the nearest hundredth.

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.

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]

☆Explanation:
¤ We that area of a Rectangle = length × breadth
¤ Here, it is said to find the area of the given figure.
Now,
Area of first Rectangle = length × breadth
= 9 cm × 4 cm
= 36 cm²
Again,
Area of the second Rectangle = length × breadth
= 14 - 4 × 5
= 10 × 5
= 50 cm²
Finally,
Area of the figure = Area of first Rectangle + Area of second Rectangle.
= 36 cm² + 50 cm²
= 86 cm²

Hi!
Your answer is 8 1-quart containers.
There are 4 quarts in a gallon.
If there is a 2-gallon bucket, and she needs to fill it using 1-quart containers, we simply multiply the number of quarts in a gallon (4) by the number of gallons total (2).

2. painting 1/2 of Dalia's room requires 10 cans of paint
3. Dalia's entire room requires 20 cans of paint
4. 3 cans of paint will cover 60% of Dalia's room
5. Dalia's entire room requires 5 cans of paint
THANK YOU WILL ADD BRAINLIEST FOR RIGHT ANSWER
Answer:
4. 3 cans of paint will cover 60% of Dalia's room
5. Dalia's entire room requires 5 cans of paint
Step-by-step explanation:
If Dalia has painted 1/10 of her room with 1/2 can of paint, then she will paint 2/10 of her room with 1 can of paint (since there are 2 halves in a whole).
2/10 = 1/5 ⇒ 1 can of paint covers 1/5 of the room.
Therefore, to paint the entire room, she will need 5 cans of paint.
60% of 5 cans of paint = 0.6 × 5 = 3
Therefore, 3 cans of paint will cover 60% of the room.

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.

The question is an illustration of conditional probability, and the value of the conditional probability P(A|B) is 0.38
How to determine the value of the probability expression?The question is incomplete, as the required parameters are not given.
So, I will give a general explanation.
The question is an illustration of conditional probability
What is a conditional probability?The conditional probability is used to determine the probability of an event, given that another independent event has already occurred.
The conditional probability is calculated using:
P(A|B) = n(A and B)/n(B)
Assume the following parameters
n(A and B) = 9
n(B) = 24
The equation to calculate the probability expression is represented as:
P(A|B) = n(A and B)/n(B)
Substitute the assumed values
P(A|B) = 9/24
Evaluate the expression
P(A|B) = 0.38
Hence, the value of the conditional probability P(A|B) is 0.38
