Pio can wash the dishes for 1hour her sister can wash dishes for half an hour how long would they wash dishes if they work together
Answers
Answer:
Pio and her sister can finish the dishes in 20 minutes if they work together.
Step-by-step explanation:
Given that:
Pio can wash the dishes in 1 hour or 60 minutes
Her sister can wash the dishes in half hour or 30 minutes.
Let,
x be the time it would take for both of them.
[tex]\frac{1}{Pio's share}+\frac{1}{Her\ sister\ share} = \frac{1}{x}\\\\\frac{1}{60}+\frac{1}{30} = \frac{1}{x}\\\\\frac{1+2}{60}=\frac{1}{x}\\\\\frac{3}{60} = \frac{1}{x} \\\\\frac{1}{20}=\frac{1}{x} \\\\x=20[/tex]
Hence,
Pio and her sister can finish the dishes in 20 minutes if they work together.

Find the average rate of change of the function
f(x)=(1/x-7)
as x changes from x=-2 to x=5
Answers
Answer:
[tex] -\frac{1}{18} [/tex]
Step-by-step explanation:
Average rate of change = [tex] \frac{f(b) - f(a)}{b - a} [/tex]
Where,
a = -2,
f(a) = f(-2) = [tex] \frac{1}{(-2) - 7} = \frac{1}{-9} [/tex] = -⅑
f(a) = -⅑
b = 5
f(b) = f(5) = [tex] \frac{1}{(5) - 7} = \frac{1}{-2} [/tex] = -½
f(b) = -½
Plug in the values into the equation
Average rate of change = [tex] \frac{-\frac{1}{2} - (-\frac{1}{9}}{5 -(-2)} [/tex]
[tex] = \frac{\frac{-9 - (-2)}{18}}{7} [/tex]
[tex] = \frac{\frac{-7}{18}}{7} [/tex]
[tex] = \frac{-7}{18} * \frac{1}{7} [/tex]
[tex] = \frac{-1}{18} * \frac{1}{1} [/tex]
[tex] = \frac{-1}{18} * 1 [/tex]
[tex] = -\frac{1}{18} [/tex]

4x-2
Step-by-step explanation:
Here are 4 equations defining 4 different functions, a, b,c, and d. List them in order of
increasing rate of change. That is, start with the one that grows the slowest and end
with the one that grows the quickest.
a. (x) = 5x + 3
b. (x) = 3x + 5
c. (x) = x +4
d. (x) = 1 + 4x
Answers
Step-by-step explanation:
In order to test the rate of growth of the functions, we use a single value of x to monitor the results of all the equation.
Let's use a random value of 3;
The equation with the highest result is the one that grows the quickest
a. (x) = 5x + 3
a. (x) = 5(3) + 3 = 18
b. (x) = 3x + 5
b. (x) = 3(3) + 5 = 14
c. (x) = x +4
c. (x) = (3) +4 = 7
d. (x) = 1 + 4x
d. (x) = 1 + 4(3) = 1 + 12 = 13
Upon going through the results and arranging in increasing order;
c. (x) = x +4
d. (x) = 1 + 4x
b. (x) = 3x + 5
a. (x) = 5x + 3

Answers
9514 1404 393
Answer:
y =1/8(x -1)^2
Step-by-step explanation:
The vertex is halfway between the focus and directrix, so has y-coordinate (2-2)/2 = 0. The x-coordinate of the vertex is the same as that of the focus. The focus-vertex distance (p) is 2-0 = 2. Where the vertex is (h, k), the equation is ...
y = 1/(4p)(x -h)^2 +k
For p=2, (h, k) = (1, 0), the equation of the parabola is ...
y = 1/8(x -1)^2

I had $13.00. My Mom gave $10.00. My Dad gave $30.00. My Aunt, My Uncle and grandma gave me $100.00. I had another $7.00. How much did I have?
Answers
The amount of money one has is $160
Amount of money one already has = $13 +$7 = $20.........(1)
Money given by Mom = $10 ...........(2)
Money given by Dad = $30.............(3)
Money given by Uncle , Aunt and grandma = $100...........(4)
Total amount of money one has can be found out by adding equation (1) , (2) (3) and (4) hence we can write
Total amount of money one has = Amount of money one already has + Money given by Mom+ Money given by Dad + Money given by Uncle , Aunt and grandma

in 2013 the median weekly earnings of young adults with bachelor degrees were $1108. This represents a 43% increase over the weakly median earnings of young adults with associate degrees. Find the median weekly earnings of young adults with associate degrees in 2013. Round to the nearest whole dollar.
Answers
Answer:
Round to the nearest whole dollar, the median weekly earnings of young adults with associate degrees in 2013 were $ 775.
Step-by-step explanation:
Given that in 2013 the median weekly earnings of young adults with bachelor degrees were $ 1108, and this represents a 43% increase over the weakly median earnings of young adults with associate degrees, to determine the median weekly earnings of the latter, the following must be done calculation:
X x 1.43 = 1108
X = 1108 / 1.43
X = 774.82
Therefore, round to the nearest whole dollar, the median weekly earnings of young adults with associate degrees in 2013 were $ 775.

Answers
Answer:
Lucky Chances” lottery a box has 100 balls. 60 balls are marked “Good.” 40 balls are marked, “Bad.” To play this lottery, you draw a ball at random and look
Over the course of 500 plays, you can expect to draw a "Good" ball 300 times.
Over the course of 500 plays, you can expect to draw a "Bad" ball 200 times.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
The probability of drawing a "Good" ball is 60/100 or 0.6.
The probability of drawing a "Bad" ball is 40/100 or 0.4.
We can use these probabilities to determine what will happen over the course of 500 plays:
On average, you can expect to draw a "Good" ball 0.6 times for every play. So over the course of 500 plays, you can expect to draw a "Good" ball 0.6 x 500 = 300 times.
On average, you can expect to draw a "Bad" ball 0.4 times for every play. So over the course of 500 plays, you can expect to draw a "Bad" ball 0.4 x 500 = 200 times.
Note that these are expected values based on the probabilities, and there is no guarantee that you will actually draw exactly 300 "Good" balls and 200 "Bad" balls.
However, over a large number of plays, the actual results should approach these expected values.
Thus,
Over the course of 500 plays, you can expect to draw a "Good" ball 0.6 x 500 = 300 times.
Over the course of 500 plays, you can expect to draw a "Bad" ball 0.4 x 500 = 200 times.
