How many lines, if any, of symmetry are shown on kite ABCD?
A) 1
B) 2
C) 3
D) none
Answers
In a kite, generally there is only 1 line of symmetry which runs from the vertex angle where the two sides of unequal length meet to the vertex angle directly opposite. Therefore, in the case of kite ABCD, the correct answer is option A) 1 line of symmetry.
Explanation:In the field of mathematics, a kite is a quadrilateral shape with two pairs of adjacent sides that are the same length. When thinking about the lines of symmetry, you should keep in mind that symmetry means that one half of the figure is a mirror image of the other half. For a kite, the number of lines of symmetry is generally 1. The line of symmetry in a kite runs from the vertex angle where the two sides of unequal length meet, to the vertex angle directly opposite.
This means, in the case of kite ABCD, there is 1 line of symmetry.
So, the correct option is A) 1 line of symmetry.

Answer:
13a. 0.92 miles
13b. C
Step-by-step explanation:
13a. The first ride costs $2.75 more than the second ride. Each quarter mile after the first quarter mile costs $0.75, so the difference in distance is:
0.75 d = 2.75
d = 3.67
The difference is 3.67 quarter miles, or 0.92 miles.
13b. The total cost is the cost of the first quarter mile plus the cost of the rest of the quarter miles.

The measure of [tex]\angle XBC=135\ (deg)[/tex]
Step-by-step explanation:
All the options given here will be used to find the numeric value of [tex]\angle XBC[/tex]
Here it is shown systematically.
Exterior angle theorem: Sum of two interior angles are equal to the measure of opposite exterior angle in a triangle.
To find [tex]\angle XBC[/tex]
[tex]m\angle XBC = m\angle BAC + m\angle BCA[/tex]
Plugging the values.
[tex]3p-6 = p + 4 + (84)[/tex]
[tex]3p-6 = p + 88[/tex]
Subtracting [tex]p[/tex] both sides.
[tex]2p-6 = 88[/tex]
[tex]2p = 94[/tex]
Dividing [tex]2[/tex] both sides.
[tex]p=\frac{94}{2}=47[/tex]
So plugging the value of [tex]p=47[/tex] in [tex]3p-6[/tex] we will get the measure of [tex]\angle XBC[/tex].
So [tex]\angle XBC=(3p-6)=3(47)-6=135\ (deg)[/tex]
The measure of [tex]\angle XBC[/tex] is [tex]135\ degrees[/tex].
Based on the information, the measure of Angle XBC is 278 - 4p degrees.
What's the measurements?Given that Angle ACB is 84 degrees, Angle BAC is (p + 4) degrees, and Angle XBC is (3p - 6) degrees, you can plug in these values:
(p + 4) + 84 + (3p - 6) + Angle XBC = 360
Combine the like terms involving 'p':
4p + 82 + Angle XBC = 360
Subtract 82 from both sides:
4p + Angle XBC = 278
Now, isolate Angle XBC by subtracting 4p from both sides:
Angle XBC = 278 - 4p
So, the measure of Angle XBC is 278 - 4p degrees.

Sofia has $1.90 worth of nickels and dimes. She has a total of 25 nickels and dimes altogether. Write a system of equations that could be used to determine the number of nickels and the number of dimes that Sofia has. Define the variables that you use to write the system.
Answers
Answer:
The number of dimes does Sofia has is 13 , and The number of dimes does nickles does Sofia has is 12
Step-by-step explanation:
Given as :
The net worth of nickels and dimes = $ 1.90
The total number of nickles and dimes altogether = 25
Let The number of nickles that Sofia has = n
And The number of dimes that Sofia has = d
Now,
Since The value of 1 nickle = [tex]\frac{1}{20}[/tex] dollar
And The value of 1 dimes = [tex]\frac{1}{10}[/tex] dollar
So, According to question
n + d = 25 ..........1
And $ [tex]\frac{1}{20}[/tex] × n + $ [tex]\frac{1}{10}[/tex] × d = $ 1.90
Or, n + 2 d = 38 .....2
Solving Eq 1 and 2
∵ n + 2 d = 38
or, 25 - d + 2 d = 38
or, d = 38 - 25
∴ d = 13
So, The number of dimes she has = 13
And the number of nickles = n = 25 - 13
∴ n = 12
Hence The number of dimes does Sofia has is 13 , and The number of dimes does nickles does Sofia has is 12 Answer

The average weight of a watermelon is 4.61 kg. The average weight of a coconut is 2.22 kg less than a watermelon. The total weight of an equal number of coconuts and watermelons is 140 kg. How many coconuts are there?
Answers
Since the average weight of a coconut is 2.22 kg less than a watermelon, its average weight is
[tex]4.61-2.22=2.39[/tex]Let n be the number of coconuts and watermelons. The total weight of n coconuts and n watermelons is
[tex]4.61n+2.39n = 7n[/tex]
If we want this total to be 140, we have
[tex]7n=140 \iff n=\dfrac{140}{7}=20[/tex]
So, you have 20 coconuts and 20 watermelons.
Final answer:
To find the number of coconuts, we can set up an equation using the given information. The average weight of a watermelon is 4.61 kg, and the average weight of a coconut is 2.22 kg less than a watermelon. By setting up the equation x(4.61 + 2.39) = 140 and solving for x, we find that there are 20 coconuts.
Explanation:
To solve this problem, we need to set up equations using the given information. Let's represent the number of coconuts as 'x'. The average weight of a watermelon is 4.61 kg, and the average weight of a coconut is 2.22 kg less than a watermelon, which means it is 4.61 - 2.22 = 2.39 kg. Since the number of coconuts and watermelons is equal, we can write the equation: x(4.61 + 2.39) = 140. Solving this equation, we get 7x = 140, which means x = 140/7 = 20.
Therefore, there are 20 coconuts.
A fireworks rocket is launched from a hill above a lake. The rocket will fall into the lake after exploding at its maximum height. The rocket's height above the surface of the lake is given by g(x)= -16x^2+64+80. What is the maximum height of the rocket?
A) 150 feet C) 120 feet
B) 80 feet D) 144 feet
Answers
Answer:
D
Step-by-step explanation:
At the maximum height, the value of the vertical velocity Vy equals zero. From the value of the equation, we can get the vertical velocity by its first differential.
Differentiating this, we get -32x + 64
We then equate this value to zero. This yield 32x = 64 and x = 2
We now plug the value of x back into the original expression for height.
-16(2)^2 + 64(2) + 80 = -64 + 128 + 80 = 144 feet

Write the equation of the line that is parallel to y=-0.75x and that passes through the point (8,0)
Answers
The equation of the line that is parallel to y=-0.75x and passes through the point (8,0) is y = -0.75x + 6.
Explanation:The equation of a line in the form y = mx + b represents a linear equation, where m is the slope of the line and b is the y-intercept. Since we are looking for a line parallel to y = -0.75x, we know that the new line will have the same slope. So, the equation of the new line is y = -0.75x + b. To find the value of b, we can substitute the coordinates of the point (8,0) into the equation and solve for b.
0 = -0.75(8) + b
0 = -6 + b
b = 6
Therefore, the equation of the line that is parallel to y = -0.75x and passes through the point (8,0) is y = -0.75x + 6.

Answers
Answer:
2*5*5= 50 because for each drink (2) there’s (5) different sizes and (5) flavors.
Step-by-step explanation:
A customer at an ice cream store can order a drink in 50 different ways by choosing from 2 drinks, 5 sizes, and 5 flavors, as calculated by the fundamental counting principle.
Explanation:To determine the number of ways a customer can order a drink at an ice cream store with 2 drinks, 5 sizes, and 5 flavors, we need to calculate the combinations of these options. Since each choice is independent of the others, we use the concept of the fundamental counting principle, where we multiply the number of options for each category together.
For drinks, there are 2 options. For sizes, there are 5 options, and for flavors, there are 5 options.
We multiply these options together: 2 drinks * 5 sizes * 5 flavors = 50 combinations.
Therefore, a customer can order a drink in 50 different ways.

Leona purchased a $1,000 bond having a quoted price of 99.875. She had to pay a 5.5% brokerage fee (of the selling price). What was the total cost of the bond (to the nearest whole cent)?
$943.82
$1,064.44
$534.77
$2,054.22
None of these choices are correct.
Answers
The total cost of Leona's bond is $1,053.68 when accounting for the quoted price and the 5.5% brokerage fee. Consequently, the option that correctly represents the total cost is 'None of these choices are correct.'
Explanation:Leona purchased a $1,000 bond having a quoted price of 99.875. To calculate the purchase price of the bond, we multiply the face value of the bond by the quoted price percentage:
Purchase Price = Face Value × (Quoted Price / 100) = $1,000 × (99.875 / 100) = $998.75
Next, we need to calculate the brokerage fee, which is 5.5% of the selling price. We will use the purchase price to calculate this:
Brokerage Fee = Purchase Price × (Brokerage Fee Percentage / 100) = $998.75 × (5.5 / 100) = $54.93
Lastly, we add the brokerage fee to the purchase price to find the total cost of the bond:
Total Cost = Purchase Price + Brokerage Fee = $998.75 + $54.93 = $1,053.68
Therefore, Leona's total cost for the bond is $1,053.68, which to the nearest whole cent is $1,053.68. The correct answer is 'None of these choices are correct.'
Final answer:
Leona's total cost for a $1,000 bond with a quoted price of 99.875 and a 5.5% brokerage fee is $1,053.68. Option E.
Explanation:
To calculate the total cost of the bond that Leona purchased, we need to consider both the quoted price of the bond and the brokerage fee. The quoted price of the bond is 99.875% of the face value, which means the price before the brokerage fee is 99.875/100 * $1,000 = $998.75. Then, we must calculate the brokerage fee, which is 5.5% of the selling price. Therefore, the brokerage fee equals 5.5/100 * $998.75 = $54.93.
To find the total cost of the bond, we add the price of the bond to the brokerage fee: $998.75 + $54.93 = $1,053.68. Hence, the correct answer to the nearest whole cent is $1,053.68, and the given options do not list this correct amount.
