Answer:

20 seconds

Step-by-step explanation:

The distance to cover between the lead skater and trailing skater is 40 meters

The lead skater's rate is 12 m/s

The trailing one's rate is 14 m/s

So, we can say:

second skater is accelerating, or covering up the distance, in 14 - 12 = 2 m/s

So, at a rate of 2 meters per second, how long would it take to cover 40 meters??

We use the distance formula, substitute the known and solve for unknown.

Distance Formula = D = RT

Where

D is distance

R is speed/rate

T is time

We know

r = 2 m/s

d = 40 m

t = ?

Now,

D = RT

40 = 2t

t = 40/2

t = 20 (seconds)

Hence,

it will take 20 seconds for the second skater to catch up (pass)

Answer:

249 gallons of 7% butterfat milk and 83 gallons of 3% butterfat milk

Step-by-step explanation:

If x is the gallons of 7% butterfat milk, and y is the gallons of 3% butterfat milk, then:

x + y = 332

0.07x + 0.03y = 0.06(332)

Solve the system of equations using substitution:

0.07x + 0.03(332 − x) = 0.06(332)

0.07x + 9.96 − 0.03x = 19.92

0.04x = 9.96

x = 249

y = 332 − x

y = 83

You need 249 gallons of 7% butterfat milk and 83 gallons of 3% butterfat milk.

Answer:

Step-by-step explanation:

       A line passes through the points [tex](2,-6)[/tex] and [tex](4,-3)[/tex].

To find the point-slope form of the line, we need a point on the line and the slope of the line.

As we have two points [tex](x_{1},y_{1})[/tex] and [tex](x_{2},y_{2})[/tex], the slope can be calculated as [tex]\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex].

       Slope of the line = [tex]\dfrac{-3-(-6)}{4-2}=\dfrac{3}{2}[/tex]

Given a line with slope [tex]m[/tex] and a point [tex](x_{1},y_{1})[/tex], slope-point form is [tex]y-y_{1}=m(x-x_{1})[/tex]

       Line is given by [tex]y+6=\frac{3}{2}(x-2)[/tex]

∴ The line is given by [tex]y+6=\frac{3}{2}(x-2)[/tex]

Final answer:

The correct point-slope form equation with the points (2, -6) and (4, -3) is y + 6 = 3/2(x - 2), after finding the slope of 3/2 and applying it to the point-slope formula using either of the points.

Explanation:

Firstly, let's find the slope of the line passing through the points (2, -6) and (4, -3). The slope formula is
(y₂ - y₁) / (x₂ - x₁), so plug in the values to get (-3 - (-6)) / (4 - 2) = 3 / 2.

Now we know the slope is 3/2, we can write a point-slope form equation, which is y - y₁ = m(x - x₁). We can use either of the given points; let's use (2, -6). Substituting these values into the point-slope formula gives us: y - (-6) = 3/2(x - 2).

Thus, the correct point-slope form equation produced with the points (2, -6) and (4, -3) is: y + 6 = 3/2(x - 2).

Answer:

The total profit for the six month of Jaxon's business is $335.

Step-by-step explanation:

Here, the profit in the business for the first month = $450

Now, the company suffers for loss of $ 60 per month for 4 months.

SO, the total loss in 4 months = 4 x ( loss in 1 month)

= 4 x ( $ 60)  = $240

So, the combined loss in next four months  = $ 240

Lastly, the profit in the final sixth month of business =  $ 125

So, combined PROFIT in the business = Profit in( First + Sixth)  Month  

                                                       = $ 450+ $ 125 = $575

Total loss in the six months  = $ 240

Now, total profit for the six month of Jaxon's business

= Total Profit - Total Loss

= $575 -  $ 240 = $335

Hence, the total profit for the six month of Jaxon's business is $335.

Step-by-step explanation:

12m - 15 = 3 (2m + 3)

12 m - 15 = 6m + 9

12m - 6m - 15 = 6m - 6m + 9

6m - 15 = 9

6m = 24

(1/6) 6m = 24 (1/6)

m = 4

To find the annual simple interest rate for the certificate of deposit, divide the total interest earned by the principal amount. In this case, the annual interest rate is 16%.

The amount of simple interest Luis earns each month is $20, and he earns this for the next 36 months. We can find the total interest earned by multiplying the monthly interest by the number of months: $20 x 36 = $720.

To find the annual simple interest rate for the certificate of deposit, we need to divide the total interest earned by the principal amount. In this case, the principal amount is $4500. So, the annual interest rate is calculated as: $720 / $4500 = 0.16 or 16%.

Therefore, the annual simple interest rate for the certificate of deposit is 16%.

Answer:

k=9

Step-by-step explanation:

1/4k=3(-1/4k+3)

1/4k=-3/4k+9

1/4k-(-3/4k)=9

1/4k+3/4k=9

k=9

The value of k that makes the system of equations have no solution is k = -0.25. This is because -0.25 makes the third equation parallel to the first two, resulting in no intersection or solution to the system.

The system of equations provided relates to the concept of systems of linear equations in mathematics. When a system of equations has no solution, it means the graphs of the equations do not intersect. To find the value of k where there is no solution, we determine when the planar coefficients of each equation are proportional. This occurs when the two planes are parallel and hence, do not intersect.

By examining the coefficients, we notice that dividing the coefficients from the first equation by -4 gives us the coefficients of the second equation, meaning the first two equations represent the same plane. Thus, k does not affect the first two equations. For the system to have no solutions, the third plane must be parallel to the first two, meaning the coefficients must have a ratio equal to k. If we set the coefficients from the third equation with the coefficients from the first one, we end with the proportion k/1 = 1/-4 = 3/10. Solving for k gives us a value of -0.25.

The width of the rectangle is [tex]\frac{2}{9}[/tex] unit

Step-by-step explanation:

The given is:

We need to find the width of the rectangle

Assume that the width of the rectangle is x units

∵ The area of the rectangle = length × width

∵ The width of the rectangle = x units

∵ The length of the rectangle = 19 units

∴ The area of the square = 19 × x = 19 x units²

∵ The width of the rectangle is 4 less than its area

- That means subtract 4 from the area to find the width

∴ x = 19 x - 4

- Subtract 19 x from both sides

∴ -18 x = -4

- Divide both sides by -18

∴ x = [tex]\frac{-4}{-18}[/tex]

- Reduce the fraction by dividing up and down by -2

∴ x = [tex]\frac{2}{9}[/tex]

Answer:

$1677

$40677

Step-by-step explanation:

Compared to the price of the current model sports can the next model price will be 4.3% higher.

The cost of the current model sports car is $39000.

Therefore, the price will increase in the next model by [tex]\frac{39000 \times 4.3}{100} = 1677[/tex] dollars. (Answer)

Now, the price of the next model will be $(39000 + 1677) = $40677 (Answer)

The price increase in dollars for the next sports car model, priced at 4.3% more than the current value, is $1,677. So, the next model of the sports car will cost $40,677.

The subject of this question is about the calculation of a price increase in mathematical terms. If the next model of a sports car is going to cost 4.3% more than the current model, which costs $39,000, then first we need to find out how much exactly 4.3% of $39,000 is. The calculation involves multiplying 39,000 by 4.3%, which comes out to $1,677.

Therefore, the price of the next model of a sports car will be the current price which is $39,000 plus the price increase in dollars i.e., $1,677. Hence, adding the two amounts gives us a total cost of $40,677 which is the price of the upcoming model.

The total number of game booths is 36, with the students setting up 30 booths denoting 5/6 of the total, and teachers setting up the remaining 6 booths which corresponds to 1/6 of the total.

The student question asks about finding the total number of game booths if 5/6 of them were set up by students, and it is known that students set up 30 booths. First, we assume the fraction 5/6 represents the portion of booths that the students were responsible for setting up. Since 5/6 equates to the 30 booths the students set up, each fraction of 1/6 represents 6 booths (30 divided by 5). As there are 6 fractions of 1/6 in a whole, to find the total (which is 6/6), you simply multiply 6 (the value of 1/6) by 6.

The calculation is as follows: 6 booths per 1/6 x 6 = 36 game booths in total. Therefore, the teachers set up the remaining sixth, which corresponds to 6 game booths, making the combined total 36. This result indicates that there is a total of 36 game booths when we include the contributions from both students and teachers.

In this case, There are 36 game booths in total.

Let's denote the total number of game booths as T.

According to the information given, 5/6 of the game booths were set up by the students.

Since the students set up 30 game booths, we can write the following equation:

[tex]\[\frac{5}{6}T = 30\][/tex]

To find the total number of game booths, T, we need to solve for T.

We can do this by multiplying both sides of the equation by the reciprocal of 5/6, which is 6/5:

[tex]\[T = 30 \times \frac{6}{5}\][/tex]

Now, we calculate the value of T:

[tex]\[T = 30 \times \frac{6}{5}\][/tex]

T = 36

 Therefore, there are 36 game booths in total.

The volume of the solid rectangular prism with a hole is 420 cm³.

To find the volume of the solid rectangular prism with a hole, we follow these steps:

Volume of the Outer Rectangular Prism:

Using the formula V = l * w * h, where l is the length, w is the width, and h is the height of the outer rectangular prism:

Volume of the outer prism (V_outer) = 20 cm * 5 cm * 5 cm = 500 cm³.

Volume of the Rectangular Prism-shaped Hole:

Using the same formula for the inner rectangular prism:

Volume of the hole (V_hole) = 20 cm * 2 cm * 2 cm = 80 cm³.

Volume of the Solid:

Subtracting the volume of the hole from the volume of the outer prism:

Volume of the solid (V_solid) = V_outer - V_hole = 500 cm³ - 80 cm³ = 420 cm³.

Therefore, the volume of the solid rectangular prism with a hole is 420 cm³.

Rate of Interest = 10%

Time Period  = 1 year

Now, the SIMPLE INTEREST  = [tex]\frac{P \times R \times T}{100}[/tex]

or, [tex]SI = \frac{10,000 \times 10 \times 1}{100}  = 1,000[/tex]

So, the simple interest on the given principal after 1 year = Rs. 1,000
