Find the quotient 1/5 divided by 2

Final answer:

The two lines have different slopes, with the first line having a slope of -2 and the second line having a slope of 2. Since the slopes are different, the two lines intersect at exactly one point, indicating that there is one solution.

Explanation:

To determine if two lines have no solution, one solution, or an infinite number of solutions, we need to find the slopes of each line. If the slopes are different, the lines intersect at one point, indicating one solution. If the slopes are the same, but they have different y-intercepts, the lines are parallel and there is no solution. If the slopes and y-intercepts are the same, the lines coincide and there are an infinite number of solutions.

For the first line through (-1,3) and (0,1), the slope can be calculated using the formula slope (m) = (y2 - y1) / (x2 - x1). Plugging in the values, we get:

m = (1 - 3) / (0 + 1) = -2

The second line passes through (1,4) and (0,2). Using the same formula:

m = (2 - 4) / (0 - 1) = 2

Since the slopes of the two lines are different, they will intersect at exactly one point, indicating one solution.

The system of equations has one solution since the lines intersect at a single point, confirming a unique solution.

To determine if the system of equations has no solution, one solution, or an infinite number of solutions, we need to analyze the slopes and y-intercepts of the two lines.

Step 1:

Calculate the slope of each line using the formula [tex]\(m = \frac{{y_2 - y_1}}{{x_2 - x_1}}\).[/tex]

For the first line passing through (-1,3) and (0,1):

[tex]\[ m_1 = \frac{{1 - 3}}{{0 - (-1)}} = \frac{{-2}}{{1}} = -2 \][/tex]

For the second line passing through (1,4) and (0,2):

[tex]\[ m_2 = \frac{{2 - 4}}{{0 - 1}} = \frac{{-2}}{{-1}} = 2 \][/tex]

Step 2:

Calculate the y-intercept for each line using the slope-intercept form [tex]\(y = mx + b\)[/tex], where (b) is the y-intercept.

For the first line:

[tex]\[ 1 = -2 \cdot 0 + b_1 \][/tex]

[tex]\[ b_1 = 1 \][/tex]

For the second line:

[tex]\[ 2 = 2 \cdot 0 + b_2 \][/tex]

[tex]\[ b_2 = 2 \][/tex]

Step 3: Compare the slopes and y-intercepts.

Since the slopes are different (-2 for the first line and 2 for the second line), the lines are not parallel. Therefore, they will intersect at exactly one point, resulting in one solution for the system of equations.

Conclusion:

The system of equations has one solution.

    [tex]c(x)=150+16.52x[/tex]

Explanation:

The total cost is comprised of three costs, namely the flat fee for the room rental ($150), the charge person for the Italian buffet ($14 per person), and the tip (18% added to the cost of the food). With this you can build your equation:

[tex]Total\text{ }cost=$150+$14x+18\%\times (14x)[/tex]

Where x respresents the number of people attending the party.

Convert 18% to its decimal form, which is 0.18 and simplify the equation:

      [tex]Total\text{ }cost=$150+$14x+0.18\times (14x)=150+14x+2.52x\\ \\ Total\text{ }cost=150+16.52x[/tex]

Hence, calling the function c(x), it is:

           [tex]c(x)=150+16.52x[/tex], with x being the number of people attending the party, and c(x) the cost in dollars.

The function which representing the total cost of party is [tex]150+16.52x[/tex]

Let us consider that number of people who attending part be x.

The room rental amount is $150.

The charge of the Italian buffet for per person = $14

For x number of people [tex]=14x[/tex]

Since, 18% tip  added to the cost of the food.

  Tip cost [tex]=14x*\frac{18}{100} =2.52x[/tex]

Total cost of the party [tex]=150+14x+2.52x=150+16.52x[/tex]

The values are [tex]m\angle \mathrm{ABC}=62^{\circ}[/tex], [tex]m\angle \mathrm{DBE}=62^{\circ}[/tex], [tex]m\angle \mathrm{CBE}=118^{\circ}[/tex] and [tex]m\angle \mathrm{ABD}=118^{\circ}[/tex]

Explanation:

It is given that [tex]\angle \mathrm{ABC}=4x+2[/tex] and [tex]\angle \mathrm{DBE}=5x-13[/tex]

The image having these measurements is attached below:

The angles ABC and DBE are vertically opposite.

Since, vertically opposite angles are equal, [tex]\angle \mathrm{ABC}=\angle \mathrm{DBE}[/tex]

Equating the values, we have,

[tex]\begin{aligned}4 x+2 &=5 x-13 \\2+13 &=5 x-4 x \\15 &=x\end{aligned}[/tex]

Thus, the value of x is 15. Let us substitute x in the equation to find [tex]\angle \mathrm{ABC}[/tex] and [tex]\angle \mathrm{DBE}[/tex]

Thus,

[tex]\begin{aligned}\angle A B C &=4(15)+2 \\&=60+2 \\&=62\end{aligned}[/tex]

Thus, [tex]m\angle \mathrm{ABC}=62^{\circ}[/tex]

Also, substituting x = 15 in [tex]\angle \mathrm{DBE}[/tex]

We have,

[tex]\begin{aligned}\angle DBE &=5(15)-13 \\&=75-13 \\&=62\end{aligned}[/tex]

Thus, [tex]m\angle \mathrm{DBE}=62^{\circ}[/tex]

Hence, the measure of [tex]\angle \mathrm{ABC}=62^{\circ}[/tex] and [tex]\angle \mathrm{DBE}=62^{\circ}[/tex]

To find the measure of [tex]\angle \mathrm{CBE}[/tex] and [tex]\angle \mathrm{ABD}[/tex]:

Since, the angles in a straight line add up to 180°

To find [tex]\angle \mathrm{CBE}[/tex], let us add the angles and equals to 180°

[tex]\angle \mathrm{CBE}+\angle \mathrm{DBE}=180[/tex]

Substituting the value of DBE, we have,

[tex]\angle \mathrm{CBE}+62=180[/tex]

Subtracting both sides by 62,

[tex]\angle \mathrm{CBE}=118[/tex]

Thus, the measure of [tex]\angle \mathrm{CBE}[/tex] is 118°

Since,  [tex]\angle \mathrm{CBE}[/tex] and [tex]\angle \mathrm{ABD}[/tex] are vertically opposite, they are equal.

Thus, [tex]\angle \mathrm{ABD}=118[/tex]

Thus, the measure of [tex]\angle \mathrm{ABD}[/tex] is 118°

Hence, the values of the angles are  [tex]m\angle \mathrm{ABC}=62^{\circ}[/tex], [tex]m\angle \mathrm{DBE}=62^{\circ}[/tex], [tex]m\angle \mathrm{CBE}=118^{\circ}[/tex] and [tex]m\angle \mathrm{ABD}=118^{\circ}[/tex]

Answer:

So the answer is NO, the probability of an event cannot be -0.25.

Step-by-step explanation:

i) The probability or likelihood of an event cannot be negative or less than zero.

ii) The probability of an event cannot be greater than 1.

iii) If the probability of an event is 0 then the event did not or does not happen

iv) If the probability of an event is one then the event did or does happen with 100% certainty.

v) If the probability is between 0 and 1 then the event occurs wit a certainty that is less than 100%.

vi) So the answer is NO, the probability of an event cannot be -0.25.

Final answer:

The number -0.25 cannot represent the probability of an event because probability values must be between 0 and 1, and negative values are not within this range.

Explanation:

The number -0.25 cannot be the probability of an event. In probability theory, the value assigned to the likelihood of an event occurring must be within a certain range, specifically between 0 and 1, inclusive.

A probability of 0 denotes an impossible event, whereas a probability of 1 represents an event that is certain to occur. Since -0.25 is a negative number, it falls outside of this acceptable range, therefore it cannot represent the probability of an event occurring in any valid probability distribution.

Area of the heart is 178.5 cm² and Perimeter is 51.4 cm

Step-by-step explanation:

Total area of heart = Area of the square + 2 × area of the semi circle

Calculate the area of the square where side = 10 cm

⇒ Area of the square = side² = 10² = 100 cm²

Calculate the area of the 2 semicircles where radius = 10/2 = 5 cm

⇒ Area of the semicircle = 1/2 × π × r²

⇒ Area of the 2 semicircles = 2 × 1/2 × π × r² = 3.14 × 5² = 78.5 cm²

⇒ Total area of the heart = 100 + 78.5 = 178.5 cm²

Calculate the perimeter of the heart = length of 2 sides of the square + 2 × perimeter of the semicircle (since there are 2 semicircles)

⇒ Perimeter = 10 + 10 + 2 × π × r (since perimeter of semicircle = πr)

⇒ Perimeter = 20 + 2 × 3.14 × 5 = 20 + 31.4 = 51.4 cm

Answer:

7.5 quarts

Step-by-step explanation:

2 baskets ------> make 3 quarts

1 basket ---------> makes 3/2 quarts

5 baskets -------> makes 3/2   x 5 = 15/2 = 7.5 quarts

The problem involves calculating ratios or proportional relationships. We find from a known ratio that 2 baskets yield 3 quarts of tomato sauce, and using cross-multiplication, we determine that 5 baskets would produce 7.5 quarts of tomato sauce.

This is a ratio problem. Here, we see that 2 baskets of tomatoes yield 3 quarts of tomato sauce. Hence, the ratio of baskets to quarts is 2:3. Likewise, if we increase the number of baskets to 5, the amount of tomato sauce will also increase according to the ratio. To determine how much sauce that would be, use the principle of equivalent ratios, also known as cross-multiplication.

So, (2 baskets / 3 quarts) = (5 baskets / x quarts), where x is the quantity of sauce from 5 baskets. By cross-multiplying and simplifying, you get x = (5 baskets * 3 quarts) / 2 baskets, which simplifies to x = 7.5 quarts.

So, you can make 7.5 quarts of tomato sauce from 5 baskets of tomatoes.

Final answer:

The solution set of the polynomial equation can be found by testing the given sets of roots and verifying which set satisfies the polynomial equation.

Explanation:

To find the solution set of the polynomial equation x4 - 6x3 + 10x2 + 2x - 15 = 0, we need to factor the polynomial or use numerical methods to find roots. Polynomial equations of higher degrees such as quartics can often be simplified into quadratic equations or factored based on known roots or rational root theorem. Once a root is found, it can be used for polynomial division to reduce the degree of the polynomial and find other roots. One simple numerical method to guess and check roots would be to use synthetic division with possible rational roots.

However, since the question provides the sets of the roots, we only need to verify which set of roots satisfy the equation. We can use these sets as potential solutions and substitute the roots back into the equation to see if it satisfies the equation. Since complex roots always come in conjugate pairs for polynomials with real coefficients the only possible sets of roots that can be correct are {2 + i, 2 - i, -3, -1} or {2 + i, 2 - i, 3, -1}. Now we can substitute these roots into the original polynomial to determine which set is the actual solution

To find the height of a new right triangle similar to the original with a base of 26 yards, use the ratio of sides from the original triangle (7/12) to set a proportion. Solve the proportion to get the new height as 15.2 yards (or 45.5 feet).

Since the triangles are similar, the ratio of their corresponding sides must be the same. To find the height of the new triangle with a base of 26 yards, we set up a proportion using the corresponding sides of the original triangle:
7 yards / 12 yards = height / 26 yards

By cross-multiplying and solving for the unknown height, we get:

7 yards * 26 yards = height * 12 yards

182 y = height * 12 yards

height = 182  / 12 yards

height = 15.1666667 yards

Since 1 yard = 3 feet, we convert the height to feet:

15.1666667 yards * 3 feet/yard = 45.5 feet

Therefore, the height of the new right triangle is approximately 15.2 yards or 45.5 feet when rounded to the nearest tenth of a foot.

Step-by-step explanation:

The given is:

We need to find the ratio between the sheets of paper to the reams in simplest form

∵ The number of the sheets is 4000

∵ The number of the reams is 8

→ sheet  :  ream

→ 4000  :  8

to simplify the ratio divide the two terms by the same number

Left: 3.5 miles per hour

Right: *equation- 12.5+2.5x=27.5*

6 pairs of socks

Step-by-step explanation:

Left:

First, make a ratio of 0.875 miles/15 minutes. (I converted to decimal form) Next, I made another ratio of x miles/60 minutes. This tells me how many miles she ran in an hour.

Then, to get from 15 minutes to 60 minutes(1 hour), I divided 60 by 15, and got 4. Since to get from 15 to 60 is to multiply by 4 in the denominator, you will also have to multiply 0.875 by 4 in the numerator. By doing that, you will find that x is equal to 3.5 miles.

Right:

First, I made an equation 12.5+2.5x=27.5.

12.5 represents the cost of one shirt.

2.5 represents the cost of a pair of socks

x represents the unknown amount of socks.

27.5 represents the total amount of money she spent.

Next, my goal is to figure out what x is, so I substracted 12.5 from both sides in order to get x to be alone. *Result: 2.50x=15

Then, I divided 2.50 from both sides, and got x=6
