What is the answer to the jones family plans a trip to the amusement park...
Answers
This is because all of the costs of the different items will add up depending on how much of them the family buys. This is why they all have the corresponding variables next to the prices. The prices of those items will be added on to the initial cost of the 128$ family package, so all of the prices would be added up together to get the total.

The area of a sector of a circle is given by the formula below. What is the solution for S?
Answers
where
[tex]A[/tex] is the area of the sector
[tex]s[/tex] is the central angle
To solve for [tex]s[/tex], we are going to divide both sides of the equation by [tex] \pi r^2[/tex], and then we are going to multiply both sides of the equation by 360°:
[tex]A= \pi r^2( \frac{s}{360} )[/tex]
[tex] \frac{A}{\pi r^2} = \frac{ \pi r^2( \frac{s}{360} )}{\pi r^2} [/tex]
[tex] \frac{s}{360}= \frac{A}{\pi r^2} [/tex]
[tex]\frac{s}{360}(360)= \frac{A}{\pi r^2} (360)[/tex]
[tex]s= \frac{360A}{\pi r^2} [/tex]

e. A parachute is laid out on the gym floor. The parachute has a radius of 16 feet. Which measurement is closest to the circumference of the parachute in feet.
Answers
C = 2 * pi * r
Where,
r: radius of the circle.
Substituting values we have:
C = 2 * 3.14 * 16
C = 100.48 feet
Answer:
A measurement that is closest to the circumference of the parachute in feet is:
C = 100.48 feet
The circumference of the parachute is Option A (100.48 feet).
To find the circumference of the parachute, we use the circumference formula for a circle:
C = 2πr
Given the radius (r) is 16 feet, we substitute it into the formula:
C = 2π(16) = 32π
Using the approximate value of π (3.1416), we get:
C ≈ 32 × 3.1416 = 100.48 feet
Thus, the measurement closest to the circumference of the parachute in feet is 100.48 feet (Option A).

x^2 - 4x+4 = 2x-4
solve for X
subtract 2x from each side:
x^2 -6x + 4 = -4
subtract 4 from each side:
x^2 -6x = -8
add 8 to both sides:
x^2 -6x +8 = 0
factor the polynomial:
x = 4 and x = 2
using the line equation replace x with 2 and 4 and solve for y
y = 2(2) - 4 = 0
y = 2(4)-4 = 4
so the 2 points the line crosses the curve is (2,0) and (4,4)
using those 2 points you can calculate the length:
distance = sqrt((x2-x1)^2 +(y2-y1)^2
distance = sqrt( (4-2)^2 + (4-0)^2)
distance = sqrt (2^2 + 4^2)
distance = sqrt (4+16)

suppose that the weight (in pounds) of an airplane is a linear function of the amount of fuel (in gallons) in its tank. When carrying 12 gallons of fuel, the airplane weighs 2176 pounds. when carrying 46 gallons of fuel, it weighs 2399 pounds. how much does the airplane weigh if it is carrying 54 gallons of fuel?
Answers
46 - 12 = 34 gallons
2399 - 2176 = 223 pounds
so 34 gallons of gas weighs 223 pounds
find weight per pound: 223 pounds / 34 gallons = 6.5588 pounds per gallon
round to 6.6 pounds per gallon
54 gallons - 46 gallons = 8 gallons
8 gallons x 6.6 pounds per gallon = 52.8 pounds, round to 53 pounds
2399 + 53 = 2452 weight of plane with 54 gallons

The angle adjacent to the 100 degree outside the triangle is 80 degrees. We know this because it is a supplementary angle, or an angle that, when added along with another angle’s measurement, makes 180 degrees. The line is straight, so the other angle must be 80 degrees to add up with the 100 to make 180 degrees.
Now that we know the other unknown angle, we can use the fact that the sum of angles within a triangle make 180 degrees. The two angles inside the triangle that we know make 150 degrees (80 plus 50), so the final angle ‘x’ must be 30 degrees (180-150=30).

A woman can bicycle 27 miles in the same time it takes her to walk 9 miles. she can ride 10 mph faster than she can walk. how fast can she walk
Answers
Recall that distance = (rate)(time)
Walking speed = s
driving speed = s + 10 (mph)
27 mi 9 mi
Then t = ----------------- = ------------
(s+10) mph s mp
This equation has only one variable, s. We can solve it for s as follows:
( 27 mi) * (s ) = (9 mi)(s)+ 90 (mi)(mph)
27s = 9s + 90, or 18 s = 90, or s = 90/18 = 10/2 = 5. Her walking speed is 5 mph. Her riding speed is 5+10 mph, or 15 mph.
Both 5 mph and 15 mph sound reasonable, don't they? 5 mph on foot and 15 on the bike.

The probability of a 4-digit lock code without all even digits is
Answers
Answer:
it's 24, 3000, and 3000/3024
Step-by-step explanation:
The probability for a 4-digit lock code using numbers 1-9 with no repeats and not all even is 2,904/3,024.
Explanation:To solve this, we need to find the total number of possible 4-digit lock codes using digits 1-9 with no repeats and not all even, then divide it by the total number of 4-digit lock codes using digits 1-9 with no repeats. Specifically, the lock code includes 5 different even numbers (2,4,6,8), and 4 different odd numbers (1,3,5,7,9). If the lock code is all even, we will have 5*4*3*2 = 120 possibilities. However, the total possibilities for 4-digit lock codes are 9*8*7*6 = 3,024. Thus the number of codes that are not all even digits is 3,024 - 120 = 2,904. Therefore, the probability for a 4-digit lock code not having all even digits is 2,904/3,024.

Given that AB is the bisector of DC. The third options of all the options are True.
B is the midpoint of DC.
In geometry, to bisect an entity means to disassociate it into two equal parts. A bisector is a line, ray, or segment that divides an entity into two equal parts. For illustration, a line that bisects an angle divides the angle into two angles with equal measures. A segment that bisects a line segment divides the line segment into two segments with equal lengths. A ray that bisects an angle extends from the vertex of the angle and divides the angle into two angles with equal measures.
As it is given that AB is the bisector of DC,
therefore, B, being the foot of AB on CD is the midpoint of DC.

x - y = 2
Set up a set of equations and add.
x + y = 16
x - y = 2 Now add
2x = 18 Divide by 2
x = 18/2
x = 9
x + y = 16
9 + y = 16 Subtract 9 from both sides.
y = 16 - 9
y = 7

There is a spinner with 15 equal areas, numbered 1 through 15. If the spinner is spun one time, what is the probability that the result is a multiple of 5 or a multiple of 3?
Answers
Answer:
1/15
Step-by-step explanation:
The probability of spinning a number on a spinner with 15 equal areas that is a multiple of 5 or a multiple of 3 is 7/15, as there are 7 favorable outcomes (3, 5, 6, 9, 10, 12, 15) out of 15 possible results.
Explanation:The question asks for the probability of spinning a number that is either a multiple of 5 or a multiple of 3 on a spinner with 15 equal areas numbered 1 through 15. To solve this, we need to identify the multiples of each within the range of numbers on the spinner and then use the principles of probability to find the chances of landing on one of those multiples when the spinner is spun once.
The multiples of 5 between 1 and 15 are 5, 10, and 15. The multiples of 3 are 3, 6, 9, 12, and 15. Note that 15 is a multiple of both 5 and 3, so it should only be counted once. To avoid overcounting, we will list each multiple only once, which gives us the numbers 3, 5, 6, 9, 10, 12, and 15. The probability of landing on any specific number on the spinner is 1 out of 15 because there are 15 equally likely outcomes.
Since we have 7 such favorable outcomes, the probability is calculated as the number of favorable outcomes over the total number of possible outcomes, which is 7/15. So, the probability of spinning a number that is a multiple of 5 or a multiple of 3 on one spin is 7/15.

Find the fifth roots of 32(cos 280° + i sin 280°).
Answers
= 32 (cos (k* 360 + 280) + isin (k*360 + 280)), where k = integer
II) z^ (1/5) = (32 (cos (k*360 + 280) + i sin (k*360 + 280))) ^ (1/5)
then,
z^ (1/5) = 2(cos ((k*360 + 280)/5) + i sin((k*360 + 280)/5))
We apply De Moivre's theorem:
z^ (1/5) = 2(cos(72k + 56) + i sin (72k +56))
We can get the five roots by assigning k = 0, 1, 2, 3, and 4
When K = 0, 1st root = 2 + i sin (cos 56 + i sin 56)k = 1, 2nd root = 2 (cos 128 + i sin 128)k = 2, 3rd root = 2 (cos 200 + i sin 200)k = 3, 4th root = 2 (cos 272 + i sin 272)k = 4, 5th root = 2 (cos 344 + i sin 344)
The fifth root is 5th root = 2 (cos 344 + i sin 344)
Correct Answer:
z1= 2(cos 56 deg + i sin 56 deg)
z2= 2(cos 128 deg + i sin 128 deg)
z3 = 2(cos 200 deg + i sin 200 deg)
z4 = 2(cos 272 deg+ i sin 272 deg)
z5 = 2(cos 344 deg+ i sin 344 deg)
Step-by-step explanation:
De Moivre's Theorem--> e^i theta = cos theta + i sin theta
The fifth root of 32 is 2 and 280/5 is 56
z1= 2(cos 56 deg + i sin 56 deg)
360deg/ 5 = 72 deg
(If it was asking for cubed root u would do 360/3. whatever the root is you divide that by 360)
z2= 2(cos 56 + 72) + (i sin 56 + 72)
z2= 2(cos 128 deg + i sin 128 deg)
z3 = 2(cos 128 + 72) + ( i sin 128 + 72)
z3 = 2(cos 200 deg + i sin 200 deg)
z4 = 2(cos 200 + 72) + (i sin 200 + 72)
z4 = 2(cos 272 deg + i sin 272 deg)
z5 = 2(cos 272 + 72) + (i sin 272 + 72)
z5 = 2(cos 344 deg + i sin 344 deg)
