What is the area and perimeter of a heart
Area of the heart is 178.5 cm² and Perimeter is 51.4 cm
Step-by-step explanation:
Step 1:Total area of heart = Area of the square + 2 × area of the semi circle
Step 2:Calculate the area of the square where side = 10 cm
⇒ Area of the square = side² = 10² = 100 cm²
Step 3: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
Step 4:⇒ Total area of the heart = 100 + 78.5 = 178.5 cm²
Step 5: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

A sports team is throwing an end-of-season party at the fitness club. The costs associated with the party include a $150 flat fee for the room rental and a $14 per person charge for the Italian buffet. An 18% tip must be added to the cost of the food. Express the total cost for the party as a function of the number of people attending
Answer:
[tex]c(x)=150+16.52x[/tex]
With x being the number of people attending the party, and c(x) the cost in dollars.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]
Total cost :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]

A right triangle has a base of 12 yards and a height of 7 yards. If you were to construct a similar but not congruent right triangle with a base of 26 yards, what would be the height of your new triangle rounded to the nearest tenth?
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.

There are 5 pennies for every 6 quarters in Ahmed's pocket. Could Ahmed have a total of 30 coins in his pocket? Explain
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.
Explanation: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.

Amy has a collection of marbles in three sizes, small, medium, and large. She has five times as many small marbles as medium marbles. The number of large marbles is two more than three times the number of medium marbles.
Let x represent the number of medium marbles Amy has. Write an algebraic expression to represent the number of small marbles she has.
Write an algebraic expression to represent the number of large marbles she has.
If Amy has a total of 560 marbles, how many of each size does she have? Show your work.
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.

What is the measure of angle ABC 4x+2, angle DBE, 5x-13, angle CBE angle ABD
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]

Three runners run along a 1.5 mile trail one Saturday morning. The graph shows the runners’ locations starting at 9:00 a.m.
who runs fastest?
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.

A system of equations consists of two lines. line one passes through (-1,3) and (0,1). the other line passes through (1,4) and (0,2). determine if the pair has no solution, one solution, or an infinite number of solutions.
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.
