(1-52/2+5)=(1-26+5)=(-25+5)=-20
continuing:
-20*2*6*6= -40*6*6=-240*6=-1440
result: -1440
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.
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.

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.

Answer: C
Geometry PLEASE HELP ASAP! Randy wants to attach a 14 foot string of lights to the top of the 12 foot mast of his sailboat. How far from the base of the mast should he attach the end of the light string? Round your answer two decimal places.
The answer is 7.21.
Randy should attach the end of the light string approximately 7.21 feet from the base of the mast using the Pythagorean theorem, as the distance from the base to the end of the string forms the leg of a right-angled triangle with the mast and the string itself.
Explanation:To solve Randy's problem, we need to use the Pythagorean theorem, which is applicable because we are dealing with a right triangle formed by the mast, the ground, and the string of lights. The mast is one leg of the triangle, and the string of lights is the hypotenuse. We are trying to find the length of the other leg, which is the distance from the base of the mast to the point where the end of the light string will be attached.
The formula for the Pythagorean theorem is:
a² + b² = c²
Where:
a is one leg of the triangleb is the other leg of the trianglec is the hypotenuse (the side opposite the right angle)In this scenario, a is the mast with a known length of 12 feet, c is the string of lights with a known length of 14 feet, and b is the distance from the base of the mast we need to calculate.
By substituting the known values into the theorem, we have:
12² + b² = 14²
Which simplifies to:
144 + b² = 196
Subtracting 144 from both sides:
b² = 196 - 144
b² = 52
Then, take the square root of both sides:
b = √52
After calculating, we find that:
b ≈ 7.21 feet
So Randy should attach the end of the light string approximately 7.21 feet from the base of the mast to reach the top.

GameStop has the Xbox one advertised for 15% off the original price of $350 plus 6% sale tax online Xbox one is advertised at Best Buy for $310.00 plus 9% sales tax which is the better buy
GameStop's total will be 371.00
Best Buy's total will be 337.90
Best Buy will be the better buy
Your answer is Best Buy
Answer:
The best option for buying the Xbox One is GameStop, as the final price would be of $315.35.
Step-by-step explanation:
GameStop: To obtain the price in GameStop, we must first obtain the 15% discount on the price of 350, and subtract it from the initial price. Then, we must calculate the amount of the tax and add it to the price to obtain the final price.
(350 - (350 x 0.15)) x 1.06 = $315.35
Best Buy: Instead, at Best Buy we simply add the sales price tax.
310 x 1.09 = $337.90

Order the correlation coefficients from weakest to strongest negative correlation -0.59 , -0.18 , -0.82 , -0.37
The correlation coefficients from weakest to strongest negative correlation can be arranged as -0.18, -0.37, -0.52, and -0.82.
What is the correlation coefficient?The correlation coefficient helps us to know how strong is the relation between two variables. Its value is always between +1 to -1, where, the numerical value shows how strong is the relation between them and, the '+' or '-' sign shows whether the relationship is positive or negative.
1 indicates a strong positive relationship.-1 indicates a strong negative relationship.A result of zero indicates no relationship at all, therefore, independent variable.Given the correlation coefficients as -0.59 , -0.18 , -0.82 , -0.37. Now, as we know that the number closest to 1 is stronger, while the number closest to 0 is weakest. Therefore, the correlation coefficients from weakest to strongest negative correlation can be arranged as,
-0.18 < -0.37 < -0.59 < -0.82
Hence, the correlation coefficients from weakest to strongest negative correlation can be arranged as -0.18, -0.37, -0.52, and -0.82.

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.

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.

A __________ is NOT rigid motion transformation.
rotation
dilation
translation
reflection
*(The Answer)*= C. Dilation
*(Explanation)*= If you search than you will find that translation, rotation, and refection or the one that are ridged, however, dilation is.
Answer:
The correct option is 2. A dilation is NOT rigid motion transformation.
Step-by-step explanation:
Rigid motion transformation : A transformation is called a rigid motion transformation if a point or object is moved, but the size and shape remain the same.
In rotation, the point of figure is rotated about the center of rotation but the size and shape remain the same.
Therefore rotation is a rigid transformation and option 1 is incorrect.
In dilation, the figure is stretched of compressed by the scale factor k along the center of dilation, so the size of figure is either increase of decrease.
Therefore dilation is not a rigid transformation and option 2 is correct.
In translated, the point of figure is shifted but the size and shape remain the same.
Therefore translation is a rigid transformation and option 3 is incorrect.
In reflection, the point of figure is reflected about the line of reflection but the size and shape remain the same.
Therefore reflection is a rigid transformation and option 4 is incorrect.

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.
