5. Garrett and Jeffrey are planning a treasure hunt. They decide to place a treasure at a point that is a
distance of 5 units from the x-axis and 3 units from the y-axis. Jeffrey places a treasure at point J, and
Garrett places one at point G. Who put the treasure in the right place? Explain how you know.
Answer:
Garret placed the treasure at the right place.
Step-by-step explanation:
The Cartesian plane can be used to locate the position of any given point with a coordinate. It consists of two numbered lines perpendicular to each other and intersecting at point zero of the lines.
From the statements given, 5 units from x-axis is not the same as 5 units on x-axis. Also, 3 units from y-axis is not the same as 3 units on y-axis.
So, distance 5 units from x-axis implies that a point 5 units after the x-axis. And also, distance 3 units from y-axis means 3 units after the y-axis.
With these conditions of the coordinate of the treasure, Garrett placed the treasure at the right place.

Max and Leah each have a lemonade stand . Max sold 12 glasses the first hour and 10 glasses each hour after that . Leah sold 8 glasses the first hour and 10 glasses each hour after that . How many glasses will each person have sold after 5 hours?
Answer:
max wil sell 52 because the first hour he sold 12 5hours -1 hour = 4 hour
4 hour × 10 p/h= 40
max sold 12+40 =52
leah will sell 58 because the first hour she sold 8
5hours - 1hour = 4 hours
4hours× 10 glasses p/h = 40
leah sold 40+8 =48 glasses
If Max and Leach sold 10 glasses each hour then after Max sold 52 glasses after 5 hours and Leach sold 48 glasses after 5 hours because it forms arithmetic progression.
What is an arithmetic progression?It is a type of sequence in which each number have a common difference from the other number. The nth term of an arithmetic progression can be calculated as a+(n-1)d.
How to calculate nth term of an A.P.?For Max we have been given that the first term is 12 and the common difference is 10.
After 10 hours the glasses which Max will sell as 12+(5-1)*10
=12+40=52 glasses
For Leach we have been given that the first term is 8 and the common difference is 10.
After 5 hours the glasses which Leach will sell as 8+(5-1)*10
=48 glasses.
Hence the number of glasses will be 52 and 48 glasses for Max and Leach.

Express 30p as a fraction of £3.00
Answer:
[tex]\frac{1}{10} \£[/tex]
Step-by-step explanation:
We know that £1 equals 100p.
Knowing this relation, we can use the rule of three
[tex]30p \times \frac{ \£1}{100p} =0.3 \£[/tex]
Then, we form the fraction
[tex]\frac{0.3 \£}{\£ 3.00} =\frac{3}{30} =\frac{1}{10} \£[/tex]
Therefore, the fraction of of £3.00 is
[tex]\frac{1}{10} \£[/tex]
A 100 gallon tank initially contains 100 gallons of sugar water at a concentration of 0.25 pounds of sugar per gallon suppose that sugar is added to the tank at a rate of p pounds per minute that sugar water is removed at a rate of 1 gallon per minute and that water in the tank is kept well mixed. What value of P should we pick so that that when 5 gallons of sugar solution is left in the tank the concentration is .5lbs of sugar/gallon?
At the start, the tank contains
(0.25 lb/gal) * (100 gal) = 25 lb
of sugar. Let [tex]S(t)[/tex] be the amount of sugar in the tank at time [tex]t[/tex]. Then [tex]S(0)=25[/tex].
Sugar is added to the tank at a rate of P lb/min, and removed at a rate of
[tex]\left(1\frac{\rm gal}{\rm min}\right)\left(\dfrac{S(t)}{100}\dfrac{\rm lb}{\rm gal}\right)=\dfrac{S(t)}{100}\dfrac{\rm lb}{\rm min}[/tex]
and so the amount of sugar in the tank changes at a net rate according to the separable differential equation,
[tex]\dfrac{\mathrm dS}{\mathrm dt}=P-\dfrac S{100}[/tex]
Separate variables, integrate, and solve for S.
[tex]\dfrac{\mathrm dS}{P-\frac S{100}}=\mathrm dt[/tex]
[tex]\displaystyle\int\dfrac{\mathrm dS}{P-\frac S{100}}=\int\mathrm dt[/tex]
[tex]-100\ln\left|P-\dfrac S{100}\right|=t+C[/tex]
[tex]\ln\left|P-\dfrac S{100}\right|=-100t-100C=C-100t[/tex]
[tex]P-\dfrac S{100}=e^{C-100t}=e^Ce^{-100t}=Ce^{-100t}[/tex]
[tex]\dfrac S{100}=P-Ce^{-100t}[/tex]
[tex]S(t)=100P-100Ce^{-100t}=100P-Ce^{-100t}[/tex]
Use the initial value to solve for C :
[tex]S(0)=25\implies 25=100P-C\implies C=100P-25[/tex]
[tex]\implies S(t)=100P-(100P-25)e^{-100t}[/tex]
The solution is being drained at a constant rate of 1 gal/min; there will be 5 gal of solution remaining after time
[tex]1000\,\mathrm{gal}+\left(-1\dfrac{\rm gal}{\rm min}\right)t=5\,\mathrm{gal}\implies t=995\,\mathrm{min}[/tex]
has passed. At this time, we want the tank to contain
(0.5 lb/gal) * (5 gal) = 2.5 lb
of sugar, so we pick P such that
[tex]S(995)=100P-(100P-25)e^{-99,500}=2.5\implies\boxed{P\approx0.025}[/tex]
a) what is the theoretical probability of landing on A ? write fraction in simplest form .
Answer:
13/50; 13/50
Step-by-step explanation:
a): Theoretical=# of favorable outcomes/# of total outcomes
To find the total, add 21+26+25+28, which is 100
A has a frequency of 26.
That would be 26/100, which is also 13/50
b): Experimental probability is based on the amount of times the spinner is spun. Since A is the only vowel in "MATH", we would take that fraction and multiply it by 100, or the number of times.
13/50*100=13*2=26
Put that over 100, which would be 26/100, which is also 13/50.

$56 they are 25% off wants to know what is the discount price
Answer:
$42
Step-by-step explanation:
This is an example of a percentage decrease.
To work out the percentage decrease you would first need to convert the percentage of 25% into a decimal. You can do this by dividing the percentage of 25 by 100, this gives you 0.25. This is because percentages are out of 100.
The next step is to minus 0.25 from 1, this gives you 0.75. This is because we are working out the percentage decrease.
To work out the discounted price you would multiply the amount of $56 by 0.75, this gives you $42.
1) Divide 25 by 100.
[tex]25/100=0.25[/tex]
2) Minus 0.25 from 1.
[tex]1-0.25=0.75[/tex]
3) Multiply $56 by 0.75.
[tex]56*0.75=42[/tex]

Find the area of the shaded region. The graph depicts the standard normal distribution with mean 0 and standard deviation 1
Answer:
[tex] P(z<1.13) = 0.8708[/tex]
And the best option would be:
[tex] 0.8708[/tex]
Step-by-step explanation:
We assume that the distribution for the random variable is:
[tex] X \sim N (\mu=0 , \sigma=1) [/tex]
For this case we want to calculate the following probability:
[tex] P(z<1.13)[/tex]
And we can use the normal standard distribution or excel and we got:
[tex] P(z<1.13) = 0.8708[/tex]
And the best option would be:

Let's think of our original price ($P) as 100%. This is also the same thing as 1 because 100% is one whole thing.
Now, we see that he got a 15% off discount. Now, we just subtract 15% from 100% to see what percent he actually payed.
100%-15%=85%
This means that $R is 85% of $P (100%).
Answer A is not correct because 0.85% is less than 1%, which is not 85%.
Answer B is not correct either because 0.15% is also less than 1%.
Answer C is correct because $R is 85% of the original cost.
I hope that this helps! Have a wonderful day!

Jake received $300 for his birthday. He must decide how much of it to save and how much to spend. His bank has a 5% interest rate. How much more would be in his account after 5 years if he saved $300 than if he saved $250?
Answer:
Assuming no compounding, given an interest rate of 5%, after 5 years the $300 dollars become:
300*(1+5%)^5= $382.884469
By saving $250 instead,
250*(1.05)^5=319.07039
The difference is 382.8845-319.0704= 63.8141
Step-by-step explanation:
The formula is FV=PV*(1+r%)^T
Where:
FV- future value
PV- present value
r%- interest rate
T- Time (usually in years)

520
Step-by-step explanation:
80 times 6.5 = 520
so she can type 520 words in 6.5 mins
Answer:
The answer would be 520
Step-by-step explanation:
We have 80 words per minutes:)
It asks how much words can we type in 6.5 minutes.
well if we do 80 words per minute we can multiply the values
80 words x 6 minutes is 480
But wait we have .5 left
so we do 80 divided by 2 and get 40
then we go 480 plus 40 and get 520
we could have straight out multiplyed it and got this but thats no fun.
520 Words for 6.5 mins :)

1) Your calculator can evaluate f(-5) for you. It will be ...
f(-5) = (1/3)^(-5) -3 = 243 -3
f(-5) = 240
So, a point on the graph is (-5, 240).
Other points on the graph will be (1, -8/3), (0, -2), (-1, 0), (-2, 6).
__
2) The given function f(x) can be written as ...
f(x) = (1/3)^x -3 = (3^-1)^x -3 = 3^-x -3
So, the transformed function is transformed by adding 1, changing the horizontal asymptote from -3 to -2. The whole graph is translated upward one unit. Each of the above-listed points will have 1 added to its y-value.
