I am going to use h for hamburgers and d for drinks to make it easier.
2h+5d=8
2h+3d=6
So what I did was make the drinks 1, this way you can see if you need to raise it or if the hamburgers could come out even. When you do that here is what it looks like:
2h+5(1)=8
2h+5=8
2h=3
h=1.50
So here is what you have as of now
h= 1.50 and d= 1
now plug that into the next problem
2h+3d=6
2(1.50)+3(1)=6
3+3=6
So that is your answer
Hamburgers are $1.50
and Drinks are $1
Hope this helps!
Hamburgers cost 1.50 each and its 1.00 for each drink

Ramona is a saleswoman whose base pay plus commissions amounted to $52561 last year. If her base pay was $23690 and she made $77,300 in sales last year, what is her rate of commission
A) 68%
B) 37%
C) 31%
D) 46%
Answer:
B) 37%
Step-by-step explanation:
Given,
The total base pay and commission = $ 52561,
While, base pay = $ 23690,
So, the amount of commision = Total base pay and commission - base pay = $ 52561- $ 23690 = $ 28871,
Also, total sale = $77,300,
Hence, the rate of the commission( in percentage )
[tex]=\frac{Commission}{Sale}\times 100[/tex]
[tex]=\frac{28871}{77300}\times 100[/tex]
[tex]=\frac{2887100}{77300}[/tex]
[tex]=37.3492884864\%[/tex]

Given that 1 kilogram weighs approximately 22 pounds, rewrite 10 pounds as an equivalent number of kilograms
Answer:
0.4545 kgs.
Step-by-step explanation:
Given that 1 kg weighs approximately 22 pounds.
i.e. 1kg= 22 lbs.
We can use this to convert lbs into kg.
22 lbs = 1 kg
Hence 1 lb = 1/22 = 0.04545 kg
Now to find out the equivalent weight for 10lbs,
we have conversion factor as 1 lb= 0.04545 kg
Hence 10 lbs = 10(0.04545) = 0.4545 kgs
Hence 10 pounds written in equivalent kgs would be0.4545 kgs.
which is the focus of a parabola with equation y^2=4x
The focus is (1,0)
Hope this helps!
Answer:
focus is (1,0)
Step-by-step explanation:
the focus of a parabola with equation [tex]y^2=4x[/tex]
Focus point lies inside the parabola
To find the focus of a parabola we need to find the vertex
the distance between the focus and vertex is the value of p.
Focus point is (h+p,k)
Where (h,k) is the vertex
Given equation is in the form of [tex](y-k)^2=4p(x-h)[/tex]
Given equation can be written as [tex](y-0)^2=4(x-0)[/tex]
So the vertex is (0,0)

As you walk to your car, you notice that your tire is nearly flat. The initial psi level yesterday was 38, but it is now only 35 today. If this trend continues and the tire keeps losing the same percentage of air, how much should be left at the end of the week?(7 days later)
Answer:
Air left in the Tyre after 1 week = 21.36 psi
Explanation:
Initial psi level = 38 psi
Psi level after 1 day = 35 psi
Percentage of remaining of air per day = (35/38)*100 = 92.10%
Ratio of remaining air per day = 0.921
Ratio of remaining air after 7 days = 0.921⁷ = 0.562
Percentage of remaining air after 7 days = 56.21%
Air left in the Tyre after 1 week = 38*56.21/100 = 21.36 psi
The student's question is about calculating the expected tire pressure at the end of a week, based on a consistent daily percentage decrease from an initial 38 psi to 35 psi. It involves a mathematical analysis using exponential decay, which is a high school level mathematics topic.
The question involves finding the projected tire pressure after a week given an initial pressure of 38 psi that has decreased to 35 psi in one day. The percentage decrease from 38 psi to 35 psi is calculated first, and then this percentage is consistently applied to find the remaining pressure after 7 days using exponential decay since the tire loses the same percentage of air each day.
Step 1: Calculate the percentage decrease.
Initial pressure (yesterday) = 38 psi
Current pressure (today) = 35 psi
Percentage decrease = ((38 - 35) / 38) x 100%
Step 2: Apply this percentage decrease for 7 days using the formula:
Pn = P0 * (1 - percentage decrease)^n
Where:
Pn is the pressure after n days
P0 is the initial pressure
n is the number of days
By calculating P7, we can find the expected pressure at the end of the week.
Step 3: Substitute the known values and calculate the expected pressure after 7 days.

Suppose you can get a higher interest rate on your savings if you maintain a balance of at least $1000 in your savings account. The balance in your savings account is now $1053. You deposit $44.50 into your account. What is the greatest amount that you can withdraw and still get the higher interest rate?
Answer:
$99.50
Step-by-step explanation:
Given that only if a minimum balance of 1000 dollars is maintained it will attract high interest.
To enjoy the privilege of high interest, it should be ensured that the balance does not go below 1000 dollars at any point of time.
Keeping the above in mind, we see that
Balance as of now .. 1053 dollars
Deposit .. 44.50 dollars
Balance after deposit .. 1097.50 dollars
Minimum balance .. 1000 dollars
Maximum amount
that can be withdrawn .. 1097.50 -1000 = 97.50 dollars.

There are 21 more days before the first big winter storm and the squirrel collects 12 acorns a day, how far away from her original amount will the squirrel be? Explain. What should the squirrel do to the bear to get even with him for eating all those acorns?
The squirrel will collect a total of 252 acorns in the 21 days before the winter storm. This is calculated by multiplying 12 acorns/day by 21 days. Instead of retaliating against a bear, the squirrel should focus on preparing for winter.
Explanation:If the squirrel collects 12 acorns a day and there are 21 more days until the big winter storm, we can calculate the total number of acorns the squirrel will collect. We do this by multiplying the number of acorns collected per day by the number of days remaining, which gives us:
12 acorns/day × 21 days = 252 acorns
After 21 days, the squirrel will have accumulated 252 acorns more than the original amount she had before the given 21-day period.
Regarding what the squirrel should do to get even with the bear for eating the acorns, it's important to remember that animals in nature often have to deal with challenges like this. The squirrel could focus on collecting more acorns, perhaps finding a better hiding place to store them, to prepare for the winter storm. However, revenge actions, such as retaliating against the bear, are not advisable nor part of natural behaviors in wildlife, and focusing on preparations for winter would be a more practical approach for survival.

for every 13 baskets mr mcdoagh made ,ms klien made 2 baskets.if mr mcdonagh made 22 more baskets than ms klien did, how many baskets did they each make.
Using a system of equations based on the ratio of baskets made by Mr. McDonagh to Ms. Klein (13 to 2) and the information that Mr. McDonagh made 22 more baskets than Ms. Klein, we determine that Ms. Klein made 4 baskets and Mr. McDonagh made 26 baskets.
To solve how many baskets each person made, we will set up a ratio and use algebra to find the number of baskets made by Mr. McDonagh and Ms. Klein. We are given that for every 13 baskets Mr. McDonagh made, Ms. Klein made 2. Let's denote the number of baskets Mr. McDonagh made as M and the number of baskets Ms. Klein made as K.
According to the ratio, we can write [tex]\frac{M }{ K} = \frac{13 }{ 2}[/tex]. We also know that Mr. McDonagh made 22 more baskets than Ms. Klein, which can be written as M = K + 22. Now we have a system of equations:
[tex]\frac{M }{ K} = \frac{13 }{ 2}[/tex]
M = K + 22
Substitute M in the first equation with (K + 22):
[tex]\frac{K+22 }{ K} = \frac{13 }{ 2}[/tex]
2(K + 22) = 13K
2K + 44 = 13K
44 = 11K
Divide both sides by 11:
K = 4
Ms. Klein made 4 baskets. Now we can find how many baskets Mr. McDonagh made by substituting K back into one of our original equations:
M = 4 + 22
M = 26
Mr. McDonagh made 26 baskets.

he minute hand of a clock moves from 12 to 10 o'clock, or five sixths of a complete revolution. Through how many degrees does it move? Through how many radians does it move?
The degree of a complete rotation is 360 degrees.
5/6th of a rotation = 5/6 X 360
that is 300 degrees.
Thus the minute hand moves 300 degrees.
(Sorry, I'm not sure about the radians ;-) )
If the minute hand of a clock moves from 12 to 10 o'clock, or five-sixths of a complete revolution, by 300 degrees it will move.
What is an angle?When two lines or rays converge at the same point, the measurement between them is called an "Angle."
It is given that, the minute hand of a clock moves from 12 to 10 o'clock, or five-sixths of a complete revolution.
The degree of a complete rotation is 360 degrees.
5/6th of a rotation it covers,
= 5/6 × 360
=300 degree
Any given angle must be multiplied by π/180 to be converted from the degree scale to the radian scale.
=300 × π/180
=5.235 radians
As a result 5.235 radians, will move.
Thus, if the minute hand of a clock moves from 12 to 10 o'clock, or five-sixths of a complete revolution, by 300 degrees it will move.
