c=1,200+215g
Step-by-step explanation:
so 1,200 each week so 1,200 per seven days. g is how many times they fill up the gas tank and the cost is 250 each time. So you have to multiply 215 by g and then add 1,200.
5. An airline ticket to Florida from a certain city costs $249. How much money does
the airline collect if 85 tickets are sold?
Answer: $21165
Step-by-step explanation:
249 x 85 = 21165
Situation:
A 33 gram sample of a substance that's
used to detect explosives has a k-value
of 0.1473.
N = Noe
-kt
No = initial mass (at time t = 0)
N = mass at time t
k = a positive constant that depends on
the substance itself and on the units
used to measure time
t = time, in days
Find the substances half life, and days. Round your answer to the nearest 10th
Answer:
Half life = 4.7 days
Step-by-step explanation:
Formula to get the final amount of the substance after the time 't',
[tex]N_t=N_0e^{-kt}[/tex]
Here, [tex]N_t[/tex] = Final amount of the substance
[tex]N_0[/tex] = Initial amount
k = decay constant
t = Duration or time
Now by substituting the values in the formula,
[tex]N_t=N_0e^{-0.1473t}[/tex]
If [tex]N_t=\frac{1}{2}(N_0)[/tex] [For half life]
[tex]\frac{1}{2}(N_0)=N_0e^{-0.1473t}[/tex]
[tex]\frac{1}{2}=e^{-0.1473t}[/tex]
[tex]2=e^{0.1473t}[/tex]
ln(2) = [tex]\text{ln}(e^{0.1473t})[/tex]
0.69315 = 0.1473t
t = 4.71 days
t ≈ 4.7 days
Therefore, half life of the substance is 4.7 days.

Find the unit rate for number of parts manufactured per hour if 1620 parts are made in 6 hours.
Answer:
270 parts per hour
Step-by-step explanation:
given
we are told that 1620 parts are manufactured in 6 hours.
Required
Unit rate.
The unit rate in this context is defined as the number of parts that can be manufactured in one hour
Step two:
To find the unit rate, we have to divide the total parts manufactured by the total time taken
unit rate= 1620/6
unit rate= 270 parts per hour

Three students have started a fence-painting business. Working together, Pragnesh and Qazi can paint the fence in 2 hours. Similarly, Pragnesh and Ronghui can paint the fence in 3 hours when they work together. Finally, when Qazi and Ronghui work together, they can paint the fence in 4 hours. How long would it take if all three students worked together to paint the fence
Answer: 55.4 mins
Step-by-step explanation:
pragnesh and qazi = 2hrs
pragnesh and roghui = 3hrs
qazi and roghui = 4hrs
this means for every 1 hour they wold paint.
pragnesh and qazi = [tex]\frac{1}{2}[/tex] half of the fence
pragnesh and roghui = [tex]\frac{1}{3}[/tex]
qazi and roghui = [tex]\frac{1}{4}[/tex] quarter of the fence
time taken when they all work together
= [tex]\frac{1}{2}[/tex] + [tex]\frac{1}{3}[/tex] + [tex]\frac{1}{4}[/tex]
= [tex]\frac{13}{12}[/tex]
= [tex]\frac{12}{13}[/tex]

20 problems correct, how many questions were on the test?
Show work please
Answer: she would get 100%
Step-by-step explanation: every correct question u get 5 points so 20 * 5 = 100
Answer:
25
Step-by-step explanation:
80% = 0.80
0.80x = 20
0.80x/0.80 = 20/0.80

How many terms are in the expression when simplified
Answer:
There are four (4) different terms
Step-by-step explanation:
Given;
2x + 3xy - (x + y) + 2
The terms are simplified as follows;
=2x + 3xy - (x + y) + 2
= 2x + 3xy - x - y + 2
collect like terms;
= 2x - x - y + 3xy + 2
= x - y + 3xy + 2
Thus, there are four (4) different terms in the simplified expression.

( PLEASE HELP , TIMED ) A pet supply store sells three dog collars and two leashes for $59.75. The same pet store sells one dog collar and three leashes for $53.75. Find the cost of one dog collar and one leash.
Answer:
how can i help also comment me i wanna talk bc im lonely lol
Step-by-step explanation:
The cost of one dog collar and one dog leash are 10.25 dollars and 14.5 dollars respectively
How to form an equation?let
the cost of each dog collars = x
the cost of each leashes = y
Therefore,
3x + 2y = 59.75
x + 3y = 53.75
Hence,
3x + 2y = 59.75
3x + 9y = 161.25
7y = 101.5
y = 101.5 / 7
y = 14.5
Therefore,
x + 3y = 53.75
x + 3(14.5) = 53.75
x = 53.75 - 43.5
x = 10.25

The domain for f(x) and g(x) is the set of all real numbers.
Let f(x) = 3x + 5 and g(x) = x2.
Find f(x) + g(x).
Answer:
f(x) + g(x) = x^2 + 3x + 5
Step-by-step explanation:
In order to do this, you need to substitute f(x) for 3x +5 and substitute g(x) for x2 (which I'm assuming is x squared, which I will be wrIting as x^2. If this is not the problem, please correct me)
f(x) + g(x) = 3x + 5 + x^2
Now, you need to put the varibles in decreasing order of exponents.
f(x) + g(x) = x^2 + 3x + 5
Answer:
Step-by-step explanation:
The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.
