Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. Expressions have the following structure: (Number/variable, Math Operator, Number/variable).
Given that you have p number of coins of pennies, n number of coins of nickels and twice as many quarters as pennies.
Thus the number of coins of quarters is 2p.
The value of penny, nickel, and quarter are
1 penny = 1 cent
1 nickel = 5 cents
1 quarter = 25 cents
The value of p number of pennies is p cents.
The value of n number of nickels is (n×5) =5n cents.
The value of 2p number of quarter is (2p × 25) = 50p cent.
The total value is p + 5n + 50p = (51p + 5n) cents
Divide 51p + 5n by 100 to convert it into dollar:

Tom is leading a workshop for 15 people. He wants each person to meet every other person (shake hands once). How many handshakes occur?
The number of handshakes that occur in Tom's workshop is 105
Given: Number of people in the workshop is 15 and Every person shakes hands once with every other person
To find: Number of handshakes
Since every person has to meet the other person only once and shake hands only once. So every handshake has only one possible combination.
Total number of combinations (handshakes) that can be possible with 15 people = [tex]15C_2[/tex]
The formula for a combination is
[tex]nC_r = \frac{n!}{r!(n-r)!}[/tex]
where n is the number of items and r is the unique arrangements.
Plugging in our numbers of n = 15 and r = 2, we get
[tex]15C_2= \frac{15!}{2!(15-2)!}\\= \frac{15!}{2! \times 13!} \\=\frac{15 \times 14 \times 13!}{2! \times 13!}\\[/tex]
On cancelling out 13! from numerator and denominator , we get
[tex]15C_2=\frac{15 \times 14}{2 \times 1}= 15 \times 7=105[/tex]
What is combination?A combination is a method of picking things from a collection in which the order of selection is irrelevant. Assume we have three numbers P, Q, and R. Combination defines how many possibilities we may choose two numbers from each set.
It is feasible to count the number of combinations in smaller collections, but the possibilities of a set of combination increases with the number of groups of elements or sets. As a result, a formula has been developed to determine the number of things that can be selected.
The formula is
[tex]nC_r = \frac{n!}{r!(n-r)!} \, when \, n > r\\nC_r = 0 \, when \, n < r[/tex]
Where n = number of distinct objects to choose from
C = Combination

Determine the prices where the revenue is zero?
For each price where the revenue is zero, explain why the revenue is zero.
Answer:
The prices where the revenue is zero are $x = 0 and $x = 125.
When x = 0, the revenue is 0 since the function is equal to zero (R(0) = -40(0)^2 + 5000(0) = 0).
When x = 125, the revenue is 0 since the coefficient of the x^2 term is negative and the coefficient of the x term is positive. Since the equation is equal to zero, the two terms must cancel each other out, resulting in zero revenue (R(125) = -40(125)^2 + 5000(125) = 0).
Step-by-step explanation:
Write an equation and solve for p. Show all work.
a) The equation is 10p + 80 = 180 and p = 10.
b) The three angles are 90°, 37°, 53°.
What is an equation?
A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.
Given that, the angles of the triangles are 53°, 2p + 17°, and 8p + 10°.
The sum of all angles of a triangle is 53° + 2p + 17° + 8p + 10° = 80 + 10p
The sum of all angles of a triangle is 180°.
Therefore,
80 + 10p = 180
Subtract 80 from both sides:
10p = 100
divide both sides by 10:
p = 10.
Putting p = 10 in 2p + 17°, and 8p + 10°:
2p + 17° = 20° + 17° = 37°
8p + 10° = 80° + 10° = 90°

One angle measures 160°, and another angle measures (3k + 61)°. If the angles are vertical angles, determine the value of k.
k = 14
k = 33
k = 74
k = 160
Answer:
Therefore, the value of k is 1.
Step-by-step explanation:
Vertical angles are pairs of angles that are opposite each other and are formed by two intersecting lines. If one angle measures 160°, the other angle must measure 180° - 160° = 20°. Therefore, if the other angle measures (3k + 61)°, we can set up the equation 20 = 3k + 61. Solving for k, we get k = -41. However, since the value of k must be a positive integer, the only possible value of k is k = 1. Therefore, the value of k is 1.

Answer:
25.5 inches.
Step-by-step explanation:
To find the length of the hypotenuse of a right triangle, you can use the Pythagorean theorem, which states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.
In this case, we have a right triangle with legs of length 19 inches and 17 inches. The length of the hypotenuse is the square root of the sum of the squares of the other two sides. We can calculate this as follows:
hypotenuse = sqrt(19^2 + 17^2)
hypotenuse = sqrt(361 + 289)
hypotenuse = sqrt(650)
hypotenuse = 25.495097568 inches

The minimum length of the slanted poles needed to support the fly is 20 feet.
What is a Pythagoras theorem?
Pythagoras' theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named Perpendicular, Base and Hypotenuse.
To find the minimum length of the slanted poles, we can use the Pythagorean theorem. The theorem states that in a right triangle, the square of the length of the hypotenuse (the slanted pole) is equal to the sum of the squares of the other two sides (the heights of the tent and fly).
We are given that the height of the tent is 12 feet and the height of the fly is 16 feet. The Pythagorean theorem can be written as follows:
c² = a² + b²
where c is the length of the slanted pole, a is the height of the tent, and b is the height of the fly.
Substituting in the given values, we get:
c² = 12² + 16²
= 144 + 256
= 400
Taking the square root of both sides gives:
c = √400
= 20
Therefore, the minimum length of the slanted poles needed to support the fly is 20 feet.

The sum of 5 consecutive odd numbers
is 145.
What is the third number in this sequence?
Hello,
I hope you and your family are doing well!
The sum of an arithmetic series is equal to the average of the first and last term, multiplied by the number of terms. Since the sum of 5 consecutive odd numbers is 145, we can set up the equation:
(a + (a + 4)) / 2 * 5 = 145
where a is the first term in the sequence.
Solving this equation gives us:
a = -23
The third number in the sequence is the third odd number after a, which is a + 4. Substituting -23 for a gives us:
(-23) + 4 = -19
Therefore, the third number in the sequence is -19.

What is an equation?
A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.
1.a
Compute the vale of 60% of 400.
Using the formula a% = a/100
60% of 400 = 60/100 of 400
Replace of by multiplication:
60% of 400 = (60/100) × 400
60% of 400 = 240.
1b.
Compute the vale of 60% of 200.
Using the formula a% = a/100
60% of 200 = 60/100 of 200
Replace of by multiplication:
60% of 200 = (60/100) ×2 00
60% of 400 = 120.
1c.
Compute the vale of 60% of 120.
Using the formula a% = a/100
60% of 120 = 60/100 of 120
Replace of by multiplication:
60% of 120 = (60/100) × 120
60% of 400 = 72.
2.
Given that 60% of x is 87.
Compute the vale of 60% of x.
Using the formula a% = a/100
60% of x = 60/100 of x
Replace of by multiplication:
60% of x = (60/100) × x
60% of x = 0.6x
Therefore the relationship is 0.6x = 87
Now divide both sides by 0.6:
x = 87/0.6
x = 145.
3a.
Given that 60% of c is 43.2.
Compute the vale of 60% of c.
Using the formula a% = a/100
60% of c = 60/100 of c
Replace of by multiplication:
60% of c = (60/100) × c
60% of c = 0.6c
Therefore the relationship is 0.6c = 43.2
Now divide both sides by 0.6:
c = 43.2/0.6
c =72.
3b.
Given that 38% of e is 190.
Compute the vale of 38% of e.
Using the formula a% = a/100
38% of e = 38/100 of e
Replace of by multiplication:
38% of e = (38/100) × e
38% of e = 0.38e
Therefore the relationship is 0.38e = 190
Now divide both sides by 0.38:
e = 190/0.38
e = 500.

PLEASE HELP ASAP!!!! FULL ANSWER ONLY!!!
A person standing close to the edge on top of a 72-foot building throws a ball vertically upward. The quadratic function h = − 16 t^2 + 84 t + 72 models the ball's height above the ground, h , in feet, t seconds after it was thrown.
a) What is the maximum height of the ball? ____________ feet
b) How many seconds does it take until the ball hits the ground? ____________ seconds
What is the maximum height of the ball 182.25 feet
How many seconds does it take until the ball hits the ground 6 seconds
How to find the maximum height of the ballThe maximum height will occur at the vertex v(h', k)
h' = -b/2a
From the equation h = − 16 t^2 + 84 t + 72
a = -16
b = 84
h' = -84/(2 * -16)
h' = t = 2.625
k = h = − 16 t^2 + 84 t + 72 at t = 2.625
= − 16 * 2.625^2 + 84 * 2.625 + 72
= 182.25 feet
The ball hits the ground when h = 0
0 = − 16 t^2 + 84 t + 72
solving the quadratic equation gives
t = 6 OR -3/4
Use the positive value
t = 6 seconds
