The total cost is $616.98.
The amount he has left to spend is $43.02.
What is the total cost?The total cost to Douglas is the sum of the total cost of the thirteen doors and the sum of the six bags of fertilizers
The total cost of the thirteen doors = (cost of one door x total number of doors that would be bought)
$43.44 x 13 = $564.72
The total cost of six bags of fertilizers = (cost of one bag x total number of bags)
$8.71 X 6 = $52.26
Total cost = $564.72 + $52.26 = $616.98
Amount he has left to spend = $660 - $616.98 = $43.02

"The unemployment rate has risen more than a percentage point to 8.9% in February from 7.1% last November." What is the relative change in the unemployment rate expressed as a percentage?
If the unemployment rate has risen more than a percentage point to 8.9% in February from 7.1% last November, then the relative change in the unemployment rate expressed as a percentage is 25.35%
Given,
The unemployment rate in February = 8.9%
The unemployment rate in November = 7.1%
The relative change in unemployment rate = [(unemployment rate in February - unemployment rate in November )÷ unemployment rate in November ] ×100
The relative change in unemployment rate= [tex](\frac{8.9-7.1}{7.1} )100[/tex]
=25.35%
Hence, If the unemployment rate has risen more than a percentage point to 8.9% in February from 7.1% last November, then the relative change in the unemployment rate expressed as a percentage is 25.35%

If an employee at Tacos R US gets paid $11.50 per hour. Find his net pay if the
employee works 38 hours in that one week. Employee has a 10% federal tax rate. SS
tax is 6.2% and Medicare tax is 1.45%
the net pay (weekly) is $359.87
How to find the net pay?First, we know that the employee wins $11.50 per hour. The employee works 38 hours per week, then the weekly pay is:
38*$11.50 = $437
Now we need to discount the taxes:
There are 10% from federal tax, 6.2% from social services and 1.45% from medicare.
The total is:
10% + 6.2% + 1.45% = 17.65%
Then we need to discount a 17.65% of the weekly pay, we will get:
$437*(1 - 17.65%/100%) = $437*(1 - 0.1765) = $359.87
We conclude that the net pay (weekly) is $359.87

Step-by-step explanation:
Answer:

Step-by-step explanation:
Let three consecutive integers be x, (x + 1), (x + 2)
According to the question, if the third of three consecutive integers is subtracted from 132, the result is the sum of the first and second.

The vertex of f(x)=x²+10x+1 is found to be (-5,-24).
The Vertex of the quadratic equation f(x)=ax²+bx+c is (h,k) where
h=-b/2a and k=f(h).
In the given question

Use equivalent ratios to answer
If out of 7 squares, 4 squares are in grey colour then if there are 15 white squares there will be 20 grey squares by solving through ratios.
Given that out of 7 squares, 4 squares are in grey colour.
We are required to find the number of grey colour squares if there are 15 white squares by using equivalent ratios.
Equivalent ratios are basically the ratios that are the same when we compare them. Two or more ratios can be compared with each other to find whether they are equivalent or not.
Ratio of white squares in 7 total squares=3:4
Total number of squares if there are 15 white squares=15*7/3=35
Number of grey squares=35-15=20
Hence if out of 7 squares, 4 squares are in grey colour then if there are 15 white squares there will be 20 grey squares by solving through ratios.

For a recent Broadway musical, orchestra main floor seats cost $148 each, and
balcony seats cost $65 each. A theatre group purchased 30 tickets for an upcoming
show in June. If the total cost of the 30 tickets was $2,614, how many of each type
of ticket did the theatre group buy?
Number of orchestra tickets
Number of balcony tickets
Answer:
Number of orchestra tickets = 8
Number of balcony tickets = 22
Step-by-step explanation:
Let the number of orchestra tickets be x and number of balcony tickets be y.
So, cost of x orchestra tickets = $148 × x = $148x
Cost of y balcony tickets = $65 × x = $65y
Also given, total number of tickets = 30
Cost of 30 tickets = $2,614
So, the system of equations that can ne formed is :
x + y = 30 ....eq 1
148x + 65y = 2614 ....eq 2
Multiplying eq 1 by 148 and subtracting eq 2 by it,
148x + 148y - 148x - 65y = 4440 - 2614
83y = 1826
y = 1826/83 = 22
Substituting y = 22 in eq 1,
x + 22 = 30
So, x = 30 - 22 = 8
Thus,
Number of orchestra tickets = 8
Number of balcony tickets = 22

When time equals 0, why is the temperature in the oven not equal to 0? Why does the temperature eventually oscillate around 350°F?
The ambient temperature, aka the outside air temperature, isn't 0 degrees Fahrenheit. This is the reason why the oven isn't at 0 degrees Fahrenheit when the oven is off. For example, if it is 68 degrees Fahrenheit outside, then the oven's temperature is likely around this figure when it is off.
------------------------------
The way the oven works is that it heats the air using a gas or electric source. Once reaching 350 or slightly higher, the oven burner will turn off for a set period of time. This is so the temperature doesn't go too far over 350.
After the burner is turned off, the air inside the oven is still really hot and will stay around 350 for a while. But the temperature will slowly decrease. Once dipping slightly below 350, the oven will turn back on to heat back up to 350 again. This process repeats over and over.
This explains why you see the oscillating bouncing curve like this. It also explains why ovens seem to go on or off in the middle of a baking session.

Hello! I'd really appreciate it if someone helped me solve this logarithm! It was my first class but the professor only showed the more simple versions :)
Answer:
(1/3)log(5) +(4/3)log(x) +log(y)
Step-by-step explanation:
You want the expanded form of the expression log(∛5·x^4·y^3).
Rules of logarithmsThe applicable rules of logarithms are ...
log(ab) = log(a) + log(b)
log(a^b) = b·log(a)
In addition to these, you need to know that a root is a fractional power: the cube root is the 1/3 power. Of course, the rules of powers tell you ...
(a^b)^c = a^(bc)
ApplicationYou can express the root as a fractional power before or after taking logs. Either way, you get the same result.
Before
[tex]\log\left(\sqrt[3]{5\cdot x^4y^3}\right)=\log\left(5^{\frac{1}{3}}\cdot x^{\frac{4}{3}}y^{\frac{3}{3}}\right)=\boxed{\dfrac{1}{3}\log(5)+\dfrac{4}{3}\log(x)+\log(y)}[/tex]
After
[tex]\log\left(\sqrt[3]{5\cdot x^4y^3}\right)=\dfrac{1}{3}\log\left(5}\cdot x^{4}y^{3}}\right)=\dfrac{1}{3}\left(\log(5)+4\log(x)+3\log(y)\right)\\\\=\boxed{\dfrac{1}{3}\log(5)+\dfrac{4}{3}\log(x)+\log(y)}[/tex]

Additional comment
Working a more complex problem is like working a simple problem, except it has more parts and may require the use of the rules more times. It may be tedious to keep track of all the parts, but it is not difficult.
