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

The area and Perimeter values of the figure are 178.5 cm² and 51.4 cm

The area of the square portion

We have;

Area of the Semicircle:

Area of Semicircle = 0.5×πr²

Answer:

    [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]

Ahmed cannot have total of 30 coins in his pocket

Solution:

Given that,

There are 5 pennies for every 6 quarters in Ahmed's pocket

We are asked if Ahmed can have a total of 30 coins in his pocket

From given,

5 pennies for every 6 quarters

Therefore, ratio is:

penny : quarter = 5 : 6

Total = 5 + 6 = 11

Then the total number of coins must be multiple of 11

But 30 is not a multiple of 11

Therefore, Ahmed cannot have total of 30 coins in his pocket

No, Ahmed cannot have a total of 30 coins in his pocket.

Yes, Ahmed could have a total of 30 coins in his pocket.

To determine how many quarters and pennies Ahmed could have, we can set up a ratio.

The ratio of pennies to quarters is 5:6.

Let the number of quarters be represented by 6x, where x is a positive integer. Then, the number of pennies would be 5x.

To find out if Ahmed could have a total of 30 coins, we need to solve the equation 6x + 5x = 30.

Combining like terms, we obtain 11x = 30. By dividing both sides of the equation by 11, we find that x = 2.7272 (repeating).

Since x must be a positive integer, we can conclude that Ahmed cannot have a total of 30 coins in his pocket.

Caedin runs fastest (he has the highest speed)

Step-by-step explanation:

The question in this problem is "who runs fastest": this means that the problem is asking us "which runner has the greatest speed?"

The speed of a body is a scalar quantity defined as

[tex]v=\frac{d}{t}[/tex]

where

d is the distance covered by the body

t is the time elapsed

In order to calculate the distance covered by each runner, we have to sum the length of all the pieces of motion, regardless of their direction.

From the graph, we observe that:

- Andy moves from x = 0 to x = 1.25 miles, so the distance covered is d = 1.25 miles. Since the time taken is 10 minutes, his speed is

[tex]v=\frac{1.25}{10}=0.125 mi/min[/tex]

- Berta moves from x = 0.5 miles to x = 1.15 miles, so the distance covered is

d = 1.15 - 0.5 = 0.65 miles

The time taken is 10 minutes, so her speed is

[tex]v=\frac{0.65}{10}=0.065 mi/min[/tex]

- Finally, Caeding moves first from x = 1.5 miles to x = 0, so he covers a distance of

[tex]d_1 = 1.5 mi[/tex]

Then he also moves from x = 0 to x = 1.0 miles, so he covers an additional distance of

[tex]d_2=1.0 mi[/tex]

So the total distance is

[tex]d=d_1+d_2=1.5+1.0=2.5 mi[/tex]

And since the time taken is 10 minutes, the speed is

[tex]v=\frac{2.5}{10}=0.25 mi/min[/tex]

Therefore, Caedin has the highest speed.

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.

Answer:

Amy has 310 small marbles, 62 medium marbles and 188 large marbles.

Step-by-step explanation:

i) Let the number of small marbles be x

ii) let the number of medium marbles be y

iii) let the number of large marbles be z

iv) Amy has 5 times as many small marbles as medium marbles therefore we can write  5y = x

v) the number of large marbles is two more than than three times the number of medium marbles therefore we can write

   z = 3y + 2

vi) Amy has a total of 560 marbles therefore we can write x + y + z = 560

vii) Therefore from i) we can write x  = 5y

viii) using vii) and v) in vi) we can write

    x + y + z  = 5y + y + 3y + 2 = 560

ix) Therefore 9y = 558   .... therefore y = [tex]\frac{558}{9}[/tex] = 62

x) Therefore from i) we get x  = y [tex]\times[/tex] 5 = 62 [tex]\times[/tex] 5 = 310

xi) Therefore z  = (3 [tex]\times[/tex] 62) + 2 =  188

Amy has 310 small marbles, 62 medium marbles and 188 large marbles.

Step-by-step explanation:

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.

Step-by-step explanation:

Prob ( first  dice = 2 and second = 2) = 1/2 * 1/2 = 1/4

Prob ( first  = 2 , second = 4) = 1/2 * 1/6 = 1/12

Prob ( first = 4 and second = 2) = 1/12.

Prob ( first = 3 and second = 1 ) = 1/36

Prob ( first = 1 and second = 3) = 1/36.

Prob ( first = 3 and second = 3) = 1/6 *1/6 = 1/36.

Prob (first = 1 and second = 1 = 1/36.
