The money the carnival committee expects to pay for prizes for that booth is $447.5
In previous years, they've discovered that 28% of students win a stuffed toy ($3.65).
14% of students win a jump rope ($1.20).
8% of students win a t-shirt ($7.50) at a booth at the school carnival.
There is no award for the remaining students. How much money should the carnival committee anticipate spending on prizes for that booth if 250 kids participate in the game at the booth.
percentage of students win a stuffed toy ( $3.65 ) = 28%
percentage of students win a jump rope ( $1.20 ) = 14%
percentage of students win a t-shirt ( $7.50 ) = 8%
Given 250 students playing the game.
Out of 250, 28% win a stuffed toy;
= 250 * (28/100)
= 70
14% win a jump rope;
= 250 * (14/100)
= 35
8% win a t-shirt;
= 250 * (8/100)
= 20
According to the total number of products sold for each quantity;
Amount of money the carnival committee expects to pay for prizes for that booth;
= ($3.65 * 70) + ($1.20 * 35) + ($7.50 * 20)
= 255.5 + 42 + 150
= $447.5
The money the carnival committee expects to pay for prizes for that booth is $447.5.

For all numbers p and q, q = 5/3p + 46 . What is the value of pwhen the value of q is 21 ?
given that for all numbers of p and q,
q = 5/3p + 46
lets find p when q is 21
so lets substitute the value of q into the given equation
q = 5/3p + 46
21 = 5/3p + 46
lets collect like terms
21 - 46 = 5/3p
-25 = 5/3p
lets cross multiply
3 X -25 = 5p
-75 = 5p
5p = -75
divide both sides by 5
5p/5 = -75/5
p = -15
therefore for all values of p and q, q = 5/3p + 46,
the value of p is -15 when q is 21

Beth is planning a playground and has decided to place the swings in such a way that they are the same distance from the jungle gym and the monkey bars. if beth places the swings at point d, how could she prove that point d is equidistant from the jungle gym and monkey bars? if segment ad ≅ segment cd, then point d is equidistant from points a and b because congruent parts of congruent triangles are congruent. if segment ad ≅ segment cd, then point d is equidistant from points a and b because a point on a perpendicular bisector is equidistant from the endpoints of the segment it intersects. if m∠acd = 90° then point d is equidistant from points a and b because congruent parts of congruent triangles are congruent. if m∠acd = 90° then point d is equidistant from points a and b because a point on a perpendicular bisector is equidistant from the endpoints of the segment it intersects.
The angle bisector theorem states that a triangle's opposite side is divided into two halves by an angle bisector that is proportional to the triangle's other two sides.
A point on a perpendicular bisector is equidistant from the endpoints of the segment it intersects, therefore if mACD = 90°, point D is equidistant from points A and B.
Any point on the perpendicular bisector is simply equal distance from both endpoints of the line segment on which it is drawn, according to the perpendicular bisector theorem.
The answer is that point is equidistant from points A and B because a point on a perpendicular bisector is equidistant from the endpoints of the segment it makes up. Therefore, if a pillar is stationed at the middle of a bridge at an angle, all the points on the pillar will be equidistant from the end points of the bridge intersects.

9) If the probability of winning a raffle is 12.5%, how many raffle tickets, out of 3200, will
be winners? Suppose that the probability to win a raffle is 3.0%. If there are 54 winning
raffle tickets, how many tickets, in total, were sold for this raffle?
If there are 54 winning tickets and the probability of winning is 3.0%, the total number of tickets sold for the raffle would be 1800.
When there is a 12.5% chance of winning, we may apply the following formula to determine the number of winning raffle tickets:
Probability of winning divided by the total number of tickets equals the number of winning tickets.
Consequently, the number of winning tickets in this instance would be:
400 winning tickets are equal to 0.125 * 3200 winning tickets.
There would be 400 winning raffle tickets out of 3200 if the chance of winning is 12.5%.
Now that 54 winning tickets have been drawn and the likelihood of winning is 3.0%, let's determine the total number of raffle tickets sold. Using the identical formula:
Total number of sold tickets is the number of winning tickets divided by the chance of winning.
54 tickets sold out of a total of 1800 tickets sold.
Therefore, If there are 54 winning tickets and the probability of winning is 3.0%, the total number of tickets sold for the raffle would be 1800.

A hemisphere-shaped bowl with radius 1 foot is filled full with chocolate. All of the chocolate is then evenly distributed between 27 congruent, smaller hemisphere-shaped molds. What is the radius of each of the smaller molds, in feet
The radius of each of the smaller molds is r = 1/3 ft. Using the volume of the given hemisphere, the required radius is calculated.
How to calculate the volume of a hemisphere?The volume of the hemisphere is calculated by using the formula,
= \(\frac{2}{3}\) × π × r³ cubic units
where r is the radius of the hemisphere.
Calculation:It is given that,
A hemisphere-shaped bowl with a radius r = 1 ft is filled with chocolate.
So, the volume of the bowl is
V = \(\frac{2}{3}\) × π × (1)³
= \(\frac{2}{3}\) × π cubic feets
The volume of each smaller hemisphere-shaped mold = \(\frac{2}{3}\) × π × r³ cubic units
So, for 27 molds, the volume = 27 × \(\frac{2}{3}\) × π × r³ cubic units
All of the chocolate is then evenly distributed between 27 congruent, smaller hemisphere-shaped molds.
Then,
\(\frac{2}{3}\) × π = 27 × \(\frac{2}{3}\) × π × r³
⇒ r³ = 1/27
⇒ r = 1/3 ft
Therefore, the required radius of each of the smaller molds is 1/3 foot.

Solve for x
HELP PLSS
The solution to the system of inequalities is x ∈ (-5/2, 5/2), which means x is any value between -5/2 and 5/2, exclusive of the endpoints.
The correct answer is option E.
To solve the inequalities, let's solve each one separately:
1) 4x - 39 > -49:
Add 39 to both sides of the inequality:
4x - 39 + 39 > -49 + 39
4x > -10
Divide both sides of the inequality by 4 (since the coefficient of x is 4 and we want to isolate x):
4x/4 > -10/4
x > -10/4
x > -5/2
So the solution to the first inequality is x > -5/2.
2) 8x + 3 < 23:
Subtract 3 from both sides of the inequality:
8x + 3 - 3 < 23 - 3
8x < 20
Divide both sides of the inequality by 8 (since the coefficient of x is 8 and we want to isolate x):
8x/8 < 20/8
x < 5/2
So the solution to the second inequality is x < 5/2.
Now, let's analyze the solutions to both inequalities:
From the first inequality, we found that x > -5/2, which means x is greater than -5/2.
From the second inequality, we found that x < 5/2, which means x is less than 5/2.
Combining these results, we can say that x must be greater than -5/2 but less than 5/2. In interval notation, this can be written as (-5/2, 5/2).

Can you explain the steps too so I can understand it better. Also if there are more than one solution can you add all of the solutions. Thank you!
Answer:
\( \rm x = - 7 \pm \sqrt{11} \)
Step-by-step explanation:
Solve for x over the real numbers:
\( \longrightarrow \) x² + 14x + 38 = 0
Subtract 38 from both sides:
\( \longrightarrow \) x² + 14x + 38 - 38 = 0 - 38
\( \longrightarrow \) x² + 14x = -38
Add 49 to both sides:
\( \longrightarrow \) x² + 14x + 49 = 49 - 38
\( \longrightarrow \) x² + 14x + 49 = 11
Write the left hand side as a square:
\( \longrightarrow \) x² + 7x + 7x + 49 = 11
\( \longrightarrow \) x(x + 7) + 7(x + 7) = 11
\( \longrightarrow \) (x + 7)(x + 7) = 11
\( \longrightarrow \) (x + 7)² = 11
Take the square root of both sides:
\( \longrightarrow \) \( \sf \sqrt{{(x + 7)}^{2}} = \pm \sqrt{11} \)
\( \longrightarrow \) \( \sf x + 7 = \pm \sqrt{11} \)
Subtract 7 from both sides:
\( \longrightarrow \) \( \sf x = - 7 \pm \sqrt{11} \)

Find an equation of the plane orthogonal to the line
(x, y, z) = (9, 5, 7) + t (-2, -4, 4)
which passes through the point (5, 7, 9).
Write the equation in the form ax + by + cz = d.
The equation of the plane orthogonal to the line (x, y, z) = (9, 5, 7) + t(-2, -4, 4) and passing through the point (5, 7, 9) can be written as -2x - 4y + 4z = 36.
To find the equation of a plane orthogonal (perpendicular) to a line, we need a direction vector of the line and a point that lies on the plane. In this case, the given line has a direction vector of (-2, -4, 4) and passes through the point (9, 5, 7).
We can start by finding a normal vector to the plane by taking the cross product of the direction vector of the line and a vector formed by subtracting the given point (5, 7, 9) from any point on the line (9, 5, 7). The cross product of (-2, -4, 4) and (4, 2, 2) gives us a normal vector of (4, 0, 0).
Using the normal vector (4, 0, 0) and the coordinates of the point (5, 7, 9), we can write the equation of the plane in the form ax + by + cz = d. Plugging in the values, we get -2x - 4y + 4z = 36.
Therefore, the equation of the plane orthogonal to the given line and passing through the point (5, 7, 9) is -2x - 4y + 4z = 36.

Ben Weatherstaff has a flower garden that is 9 m wide and 13 m long. He wants to increase the area to 221m² by increasing the width and the length the same amount. What will be the length (greater dimension) of the new flower garden?
A: 4m
B: 26m
C: 13m
D: 17m
Using area of the rectangle, we can find that the new flower garden will be 13m in length (greater dimension).
What do you mean by area?The formula for calculating a rectangle's area can be used to determine how much space the rectangle takes up within its perimeter. Multiplying the length by the width yields the area of a rectangle (breadth).
As a result, the following formula can be used to determine the area of a rectangle whose length and breadth are "l" and "w," respectively. The rectangle's area is L × W. A rectangle's area is therefore equal to length * width.
Now here the dimensions of the rectangle are, l = 13m and b, = 9m.
Area of the rectangle is 13 × 9 = 117m².
Now the area of the rectangle is increased to 221m².
So, when we increase the length from 13 m to 17m and the breadth from 9m to 13m, we get area = 17 × 13 = 221m².
Therefore, length of the new garden will be 17m long.

Solve for x by dividing both sides by 0.70:
x = 14/0.70
x = 20
The original price was $20
Answer:
Let the original price be x.
Joe paid $14.00 for a board game which is the 70% of the original price.
Therefore, the original price is
\(70\% \: of \: x = 14 \\ \frac{70}{100}x = 14 \\ x = \frac{14 \times 100}{70} \\ \boxed{ x = 20}\)
$20.00 is the right answer.an angle measures 69°. what is the measure of its complement
For the given angle of 69°, its complement is calculated as 90° - 69° = 21°.
An angle's complement is the angle that, when combined with the given angle, adds up to 90°. In this case, the given angle is 69°, so its complement is 90° - 69° = 21°.
To answer this question, we need to understand the definition of an angle's complement. An angle's complement is the angle that, when added to the given angle, forms a right angle. A right angle is an angle that measures 90°.
Using this definition, we can answer the question. The given angle is 69°, so its complement is 90° - 69° = 21°.
We can visualize this by thinking of a triangle and labeling the angles. Let's say we label the given angle as angle A, and its complement as angle B.
Since angle A + angle B = 90°, and angle A is 69°, angle B must be 21°. Therefore, the measure of the given angle's complement is 21°.
