Answer:

Option C. 832 miles

Step-by-step explanation:

Ashley travels between 204 and 272 miles in every 4 hours.

That means she travels between 51 [tex](\frac{204}{4}miles)[/tex] and 68 ([tex]\frac{272}{4}miles)[/tex] per hour.

Therefore, in 12 hours she will travel between 612 (51×12 miles) miles and 816 (68×12 miles).

Since she has already traveled 118 miles before 12 hours then the distance traveled by her till now will be between 730 (612+118 miles) and 934 (816+118 miles).

From the given options, Option C. 832 miles is the reasonable measure of Ashley's distance from the starting point.

Step-by-step explanation:

The slope-intercept form of an equation of a line:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

We have the equation of a line in a standard form.

Convert to the slope-intercept form:

[tex]2x-y=-1[/tex]         add y to both sides

[tex]2x-y+y=-1+y[/tex]

[tex]2x=-1+y[/tex]            add 1 to both sides

[tex]2x+1=-1+1+y[/tex]

[tex]2x+1=y\to y=2x+1[/tex]

The slope intercept form of the given equation is y = 2x+1

An equation is a mathematical statement that shows that two mathematical expressions are equal.

For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

(ii) 3x + 5 = 15

An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values.

Given that, an equation of a line, 2x-y = -1, we need to convert this into slope intercept form,

The standard form of the equation of a line in slope intercept form, is given by :

y = mx+c

Where, m = slope of the line, c is the y-intercept,

So, the given equation is 2x-y = -1,

Add y both the side,

2x-y+y = -1+y

2x = -1+y

Add 1 in both sides,

2x+1 = y+1-1

y = 2x+1

Hence, the slope intercept form of the given equation is y = 2x+1

Answer:

3,400,000

Step-by-step explanation:

refer to attached for reference

in our case, the digit in the hundred thousands place is the number 4.

How we round this digit depends on the digit directly to the right of it (i.e the ten-thousands place).

If the digit to the right is less than 5, then leave the digit in the hundred thousands place the same and make everything else to the right zeros.

if the digit to the right is 5 or greater, then increase the digit in the hundred thousands place by 1 and then make everything else to the right zeros.

in our case, the digit to the right of the hundred thousands place is the number 2, this is less than 5, so we leave 4 the same and make everything esle to the right zero.

i.e. 3,400,000

3,425,645 rounded to the nearest hundred thousand is 3,400,000. The rounding is based on the digit in the ten thousand's place, which is 4 in this case, so we round down.

To round the number 3,425,645 to the nearest hundred thousand, we look at the ten thousand's place which is 2. Since this digit is less than 5, we round down the hundred thousand's place. Therefore, 3,425,645 rounded to the nearest hundred thousand is 3,400,000.

When rounding to the nearest hundred thousand, the digit in the hundred thousand's place becomes the focus. If the digit in the ten thousand's place (to the right of the hundred thousand's place) is 4 or less, the hundred thousand's digit remains the same and all subsequent digits become zero. If the ten thousand's place is 5 or more, the hundred thousand's digit is increased by one, and again, all digits to the right are changed to zero.

In this example, the hundred thousand's digit is 3 and the ten thousand's digit is 4, which tells us to keep the hundred thousand's place as it is and replace the subsequent digits with zeros. This gives us 3,400,000 as the rounded number.

Answer: ( 12 , 9 )

Step-by-step explanation:

The formula for finding the coordinate of points when a line is externally divided in a given ratio is given by :

x = [tex]\frac{p x_{2}+q x_{1}}{p+q}[/tex]

y = [tex]\frac{p y_{2}+q y_{1}}{p+q}[/tex]

From the question

[tex]x_{1}[/tex] = 2

[tex]x_{2}[/tex] = ?

x = 4

[tex]y_{1}[/tex] = -1

[tex]y_{2}[/tex] = ?

y = 1

p = 1

q = 4

substituting the values into the formula ,we have

x = [tex]\frac{p x_{2}+q x_{1}}{p+q}[/tex]

4 = [tex]\frac{1(x_{2})+4(2) }{1+4}[/tex]

4 = [tex]\frac{x_{2}+8}{5}[/tex]

[tex]x_{2}[/tex] + 8 = 20

[tex]x_{2}[/tex] = 12

Also

y = [tex]\frac{p y_{2}+q y_{1}}{p+q}[/tex]

1 = [tex]\frac{y_{2}+4(-1)}{5}[/tex]

[tex]y_{2}[/tex] - 4 = 5

[tex]y_{2}[/tex] = 9

Answer:

885

Step-by-step explanation:

Given:  Amount available in the cash register= $ 125.50.

            Every item is just priced at $1.00

            Total amount of money at the end of day= $1085.60

            Sales tax rate= 8.5%

First finding total revenue generated at the end of day,

Total revenue at the end of day= [tex]Total\ cash\ at\ the\ end\ of\ day - Cash\ available\ at\ the\ beginning\ of\ day[/tex]

∴ Total revenue at the end of day= [tex]1085.6- 125.5= \$ 960.1[/tex]

Lets assume total number of item sold be "x".

Now, forming an equation to determine the total revenue generated at the end of day.

We know, Total revenue is the number of item sold at $1 and sales tax revenue generated on the number of item sold.

⇒ [tex]\$1 \times x + \frac{8.5}{100} \times x= \$ 960.1[/tex]

⇒[tex]1x+0.085x= 960.1[/tex]

⇒ [tex]1.085x= 960.1[/tex]

dividing both side by 1.085

⇒[tex]x= \frac{960.1}{1.085}[/tex]

∴ x= [tex]884.884[/tex] [tex]\approx 885[/tex]

Hence, total number item sold in the day is 885

170 ml of 20 % fungicide solution is mixed with 30 ml of 60% fungicide solution  to create 200 milliliters of a 26% solution

Solution:

The final solution has 200 ml

Let "x" be the ml of 20 % fungicide solution

Then, (200 - x) is the ml of 60% fungicide solution

Then according to question, we can say,

"x" ml of 20 % fungicide solution is mixed with (200 - x) ml of 60% fungicide solution to get 200 ml of 26 % solution

We can frame a equation as:

[tex]x \times 20 \% + (200-x) \times 60 \% = 200 \times 26 \%\\\\\text{Solve the equation for "x" }\\\\x \times \frac{20}{100} + (200-x) \times \frac{60}{100} = 200 \times \frac{26}{100}\\\\\text{Simplify the above expression}\\\\x \times 0.2 + (200-x) \times 0.6 = 26 \times 2\\\\0.2x + 120 - 0.6x = 52\\\\-0.4x = 52 - 120\\\\-0.4x = -68\\\\x = 170[/tex]

Thus 170 ml of 20 % fungicide solution is used

Then , (200 - x) = 200 - 170 = 30 ml of 60% fungicide solution is used

James needs to mix 160 milliliters of the 20% solution with 40 milliliters of the 60% solution, in order to achieve a 26% solution in a total volume of 200 milliliters.

To solve the problem, set up two equations based on the total volume and the percentage of the fungicide.

Solving these two equations simultaneously, we get x = 160 milliliters and y = 40 milliliters.

Therefore, James needs to mix 160 milliliters of 20% fungicide solution and 40 milliliters of 60% fungicide solution to get a 26% solution of 200 milliliters.

Answer:

No I don't agree with their solution; both their answers are wrong.

Correct answer is [tex]b=-30[/tex].

Step-by-step explanation:

Given:

[tex]\frac{2}{5}b+1=-11[/tex]

Now given:

According to Mai [tex]b = -25[/tex] and According to Tyler [tex]b = -28[/tex]

Now we need to find which of them is correct.

So we will solve the given equation we get;

[tex]\frac{2}{5}b+1=-11[/tex]

Subtracting both side by 1 we get;

[tex]\frac{2}{5}b+1-1=-11-1\\\\\frac{2}{5}b =-12[/tex]

Now Multiplying both side [tex]\frac{5}{2}[/tex] we get;

[tex]\frac{2}{5}b\times\frac{5}{2}= -12 \times \frac{5}{2}\\\\b=-6\times 5\\\\b=-30[/tex]

Hence both of them are incorrect, correct answer is [tex]b=-30[/tex].

Both Mai's and Tyler's solutions are incorrect. Mai's solution is incorrect as the correct solution to b is -30, not -25. Tyler's work has several typos that lead to an incorrect solution. To correctly solve the equation, you should subtract 1 from both sides to get 2/5b = -12, then multiply by the reciprocal of 2/5 which gives b = -30.

The original equation presented is 2/5b + 1 = -11. Let's verify both Mai's and Tyler's solutions:

The correct procedure should be: Subtract 1 from both sides of the equation to get 2/5b = -12. Then multiply both sides by 5/2 to solve for b, which gives a correct solution of b = -30.

The answer is D. octagon.

Therefore, the only shapes that can be formed by slicing a square prism with a plane from the given options are a rectangle, a triangle, and an octagon. A hexagon is not possible, making option C the correct answer.

The correct answer is C. A hexagon is not possible when slicing a square prism with a plane.

When slicing a square prism with a plane, the resulting cross section can take on various shapes depending on the angle and position of the cutting plane. Here are the possible cross sections:

- If the plane is parallel to one of the faces of the prism and intersects the prism, the cross section will be a rectangle (Option A).

- If the plane intersects two adjacent edges of the prism, the cross section will be a triangle (Option B).

- If the plane passes through the prism in such a way that it intersects all four edges of one face of the prism, the cross section will be an octagon (Option D), provided that the plane does not intersect the prism at the corners of the square base.

However, a hexagon (Option C) is not a possible cross section when slicing a square prism with a plane. This is because to create a hexagon, the plane would need to intersect three non-adjacent edges of the prism's base, which is geometrically impossible given the right angles of the square base. A hexagon has six sides, and a square prism's base has only four edges, which cannot be divided into three pairs of non-adjacent edges that a plane could intersect to form a hexagon.

The question involves solving simultaneous linear equations, a high school level topic in mathematics. Methods like substitution or elimination can be used to find the values of the variables.

The student's question involves solving simultaneous linear equations, which is a topic in mathematics. To solve the given system of equations, one can use methods such as substitution, elimination, or matrix operations like determinants. The elimination method can be particularly efficient. For example, you can multiply the first equation by a number that will allow the x or y terms to cancel out when added or subtracted from the second equation. After simplifying, you're left with one equation in one unknown, which can be easily solved. Then, back-substitute the known value into one of the original equations to solve for the other variable.

Given the equations 3x + 7y = -5 and 8x + 9y = 6, we may choose to multiply the first equation by 3 and the second by 7 (to eliminate the x terms) or to multiply the first equation by 8 and the second by 3 (to eliminate the y terms). Once one variable is eliminated, we solve for the other and use it to find the value of the remaining variable.

Work Shown:

f(x) = 6x + b

f(5) = 6(5) + b .... replace every x with 5

f(5) = 30 + b

1 = 30 + b ..... replace f(5) with 1, since f(5) = 1 was given.

1-30 = 30 + b - 30 .... subtract 30 from both sides

-29 = b

b = -29

-----------

The function f(x) = 6x+b turns into f(x) = 6x+(-29) which is equivalent to f(x) = 6x-29

Plugging in x = 5 leads to

f(x) = 6x-29

f(5) = 6(5) - 29

f(5) = 30 - 29

f(5) = 1

Solved given expression for x using the change of base formula log base b of y equals log y over log b is 4.459

Answer: Option D

Step-by-step explanation:

Given Expression:

             [tex]2^{x-1}=11[/tex]

To solve this, first convert the exponential form into log form

If  [tex]a^{x}=b[/tex] then [tex]\log _{a}(b)=x[/tex]

So, when comparing the given expression with above,  a = 2, x = x – 1 and b = 11 .

            [tex]2^{x-1}=11[/tex] become [tex]\log _{2}(11)=x-1[/tex]

Now, apply change of base formula to remove base 3

             [tex]\log _{a}(y)=\frac{\log y}{\log a}[/tex]

Hence,

            [tex]\log _{2}(11)=\frac{\log 11}{\log 2}[/tex]

Substitute [tex]\log _{2}(11)=x-1[/tex] in above expression, we get

           [tex]\frac{\log 11}{\log 2}=x-1[/tex]

           [tex]\frac{1.0414}{0.301}=x-1[/tex]

           x – 1 = 3.459

          x = 3.459 + 1 = 4.459

Final answer:

To solve the equation 2^(x - 1) = 11 for x, one can use the change of base formula by taking the logarithm of both sides, rewriting the equation using logarithm properties, isolating x, and then simply calculating using a calculator, which results in x ≈ 1.289.

Explanation:

To solve 2(x − 1) = 11 for x using the change of base formula, take the logarithm of both sides of the equation and use the formula logb(y) = log(y) / log(b), where y is the number we want to take the logarithm of and b is the base of the logarithm.

Let's start the process:

Now, calculate the right side of the equation using a calculator:
