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.

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.

f(x) = 2x + 1

To find the inverse, f^-1(x), of the function:

Put the function as an equation:

y = 2x + 1

Then move x to the left and y to the right;

x = 2y + 1

Then solve for y;

y = x/2 - 1/2

f^-1(x) = y

f^-1(x) = x/2 - 1/2

To solve this, first add -9b on both sides of the equation to get the variable on only one side of the equation.

2b+4=-18-9b

2b+9b+4=-18-9b+9b

11b+4=-18

Then subtract 4 from both sides of the equation.

11b+4=-18

11b+4-4=-18-4

11b=-22

Divide 11 on both sides of the equation to find the values of b.

Answer:

A is the answer

Step-by-step explanation:

The graph of the equation y = -4x+7 is a line that shows the set of all solutions of the equation.

"The equation of line is an algebraic form of representing the set of points, which together form a line in a coordinate system. The numerous points which together form a line in the coordinate axis are represented as a set of variables x, y to form an algebraic equation, which is referred to as an equation of a line. Using the equation of any line, we can find whether a given point lies on the line or not.

The equation of line is a linear equation with a degree of one"

"The equation of a line can be formed with the help of the slope of the line and a point on the line."

Here is the equation of the line is given,

y = -4x + 7

since, it is the equation of a line, it contains all the solutions on the graph.

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.

It would be -1.25 degrees at noon.

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.

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]

I did it on khan academy, and got it right!

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.

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.

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.

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)

Now we find the value of p

[tex]4p = 4[/tex]

So [tex]p=1[/tex]

Focus is (h+p,k) that is (1,0)

The answer to this question is 380

Answer:

380 dollar.

Step-by-step explanation:

John earns $437 a week after a 15% pay rise.

Let the initially pay of John be x

x + (15% of x) = 437

x + 0.15x = 437

1.15x = 437

x = [tex]\frac{437}{1.15}[/tex]

x = 380

Initially his pay was 380 dollar.

Actually neither is greater.

these two numbers are equal to each other.

All because 8.720 has an extra number doesn't mean its greater. Because the number place is 0 is gives no significant value and is therefore the same as 8.72.

The bottom line is...

8.72 = 8.720

Solution:

Let starting map of youth center has Dimension (Preimage)

1 unit of y= k units

1 unit of x = t units

The new map of youth center which is 3 times larger than original(Image)

1 unit of y= 3 k units

1 unit of x = 3 t units

Image = 3 × Pre- image

The image is larger than Pre- image.

So, Scale of the new map = 3 × The original dimension of map.
