Answer: They will need 3 total buses to fit all of the teachers and students.
Step-by-step explanation: If there are 14 students and 2 teachers with each class, that is a total of 16 people. Multiply 16 by 3 and you get 48 total people going on the field trip. Divide 48 by 20 and you get 2.4, which means two buses will be filled up to the max and they will need an extra bus to fit the rest. Hence, your answer: 3 total buses.

This is the answer:
Mass of earth: 5.97200e21 or 5.97200000000000000000000000
Mass of planes: 210000
Now, we have to divide the mass of the earth into the amount of planes.
For example, Earth/Planes.
And the answer is: 2.84380952e5. Or 2.8438095200000. I hope this helps!
You know that a rope is no more than 100 feet long. You need to cut the rope into three pieces the second piece is to be three times as long as the first piece, and the third piece must be 18 feet long. What is the maximum length of the second piece?
Answer:
hi
Step-by-step explanation:
The rope is originally 100 ft. long. The first piece is 32 ft., leaving 100–32, or 68 ft.
Let n be the second piece, and n-30 be the third piece. Then:
n+n-30=68
2n=98
n=49
n-30=19
The second piece is 49 ft. long; the third piece is 19 ft. long ……..
the solution of the equation 3(x+3)=12
Answer:
1
Step-by-step explanation:
3(x + 3) = 12
Multiply 3 by both numbers in the parentheses.
3x + 9 = 12
Subtract 9 from both sides of the equation.
3x = 3
Divide 3 from both sides of the equation.
x = 1

The probability that it is red is 1/2.
what is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
A bag with 8 marbles
4 red marbles,
3 blue marbles,
and 1 yellow marble.
So, the probability that it is red
= 4 / ( 8)
= 1/2
Hence, the probability that it is red is 1/2.

Write a cosine function that has a midline of 2, an amplitude of 4 and a period of
8/3
Answer: f(x) = 4*cos(pi*(6/8)*x) + 2
Step-by-step explanation:
A generic cosine function is written as:
f(x) = A*cos(w*x + p) + M
where:
A = amplitude
w = angular frequency
p = phase
M = midline.
We know that:
the midline is 2, then M = 2
the amplitude is 4, then A = 4
There is no information about the phase, so p = 0.
And we know that the period is 8/3.
The period is written as T, and the relation between the period and the angular frequency is:
T = 2*pi/w
Then we have:
8/3 = 2*pi/w
w = (2*pi)*(3/8) = pi*(6/8)
where pi = 3.14
Then we have:
w = pi*(6/8)
A = 4
M = 2
p = 0
Then the cosine function is:
f(x) = 4*cos(pi*(6/8)*x) + 2.

Calculate the current in an Inductor if the energy stored is 240J and the Inductance is 24H.
Answer:
Current, I = 4.47 Amperes.
Step-by-step explanation:
Given the following data;
Inductance = 24H
Energy stored, Eind = 240J
To find the current;
The energy stored in an inductor is given by the formula;
Eind = ½LI²
240 = ½*24*I²
Cross-multiplying, we have;
480 = 24I²
I² = 480/24
I² = 20
Taking the square root of both sides, we have;
Current, I = 4.47 Amp

(a) Angela and Barbra decided to start a business together. Angela invested $24000 and Barbara invested
$16000. They share all profits in the same ratio as the money was invested. they made a
total profit of $15000 at the end of the year, how much money did each person recieve?
(b) sum of money is shared among two friends in the ratio 4:9. If the smaller amount is $560, find the
larger amount.
(c) The sum $4500 is divided among Anesha, Sian and Joanne. Sian received half, Anesha received $1050
and Joanne recieved the remainder. Calculate:
i. Sian's share
ii. Joanne's share
iii. The ratio in which the $4500 was divided among the three persons in simplest form.
9514 1404 393
Answer:
(a) A : B = $9000 : $6000
(b) $1260
(c) A : S : J = $1050 : $2250 : $1200 = 7 : 15 : 8
Step-by-step explanation:
(a) The investment ratio is ...
Angela : Barbara = 24000 : 16000 = 3 : 2
The profit of 15,000 goes 3/(3+2) = 3/5 to Angela, and 2/5 to Barbara:
Angela's share: (3/5)($15,000) = $9,000
Barbara's share: (2/5)($15,000) = $6,000
__
(b) We can multiply the ratio by $140 to see the larger amount:
4 : 9 = ($140)(4) : ($140)(9) = $560 : $1260
The larger share is $1260.
__
(c) Sian gets (1/2)($4500) = $2250. Anesha gets $1050. So Joanne gets ...
$2250 -1050 = $1200
Then the shares are ...
i. Sian: $2250
ii. Joanne: $1200
iii. Ratios: A : S : J = 105 : 225 : 120 = 7 : 15 : 8

Write your answer in feet and inches. Use a number less than 12 for inches.
Answer:
10 feet 5 inches long
Step-by-step explanation:
12 inches = 1 foot

at a clothing store, levi's jeans are on sale for 40% off. sales tax is 7%. which expression will calculate the total cost of levi jeans with an original price of x?
Given:
Discount = 40%
Sales tax = 7%
To find:
The total cost of levi jeans with an original price of x.
Solution:
Let x be the original price of the jeans. Then the price after 40% discount is
[tex]Price=x-40\%\text{ of }x[/tex]
[tex]Price=x-\dfrac{40}{100}x[/tex]
[tex]Price=x-0.4x[/tex]
[tex]Price=0.6x[/tex]
The price after 7% of sales tax.
[tex]Price=0.6x+7\%\text{ of }0.6x[/tex]
[tex]Price=0.6x+\dfrac{7}{100}\times 0.6x[/tex]
[tex]Price=0.6x+0.042x[/tex]
[tex]Price=0.642x[/tex]
Therefore, the total cost of the levi jeans with an original price of x is represented by the expression 0.642x.
Because of bad weather, the number of days next week that the captain of a charter fishing boat can leave port is uncertain. The following probability distribution for the number of days that the boat is able to leave port per week was determined based on historical data when the weather was poor: The number of days the boat can leave port per week Probability 0 0.20 1 0.05 2 0.05 3 0.05 4 0.15 5 0.10 6 0.15 7 0.25 Based on the probability distribution, what is the expected number of days per week the captain can leave port. Group of answer choices 3.55 4.00 3.50 4.05 2.85
Answer:
The expected number of days per week the captain can leave port is 4.05.
Step-by-step explanation:
We are given the following distribution:
[tex]P(X = 0) = 0.2[/tex]
[tex]P(X = 1) = 0.05[/tex]
[tex]P(X = 2) = 0.05[/tex]
[tex]P(X = 3) = 0.05[/tex]
[tex]P(X = 4) = 0.15[/tex]
[tex]P(X = 5) = 0.1[/tex]
[tex]P(X = 6) = 0.15[/tex]
[tex]P(X = 7) = 0.25[/tex]
What is the expected number of days per week the captain can leave port.
We multiply each outcome by its probability. So
[tex]E = 0*0.2 + 1*0.05 + 2*0.05 + 3*0.05 + 4*0.15 + 5*0.1 + 6*0.15 + 7*0.25 = 4.05[/tex]
The expected number of days per week the captain can leave port is 4.05.

add the total amount of bows then find out of that much how many are purple
Answer:
4/10 (2/5)
Step-by-step explanation:
Add all the bows together and then add ur number to the fraction.
EX: 1 blue bow, 6 purple bows, 6, pink bows what is the possibility to get a blue bow?
Add them all together, and then the denominator would be 13. So, there is one bow which means 1 in a 13 chance you will get the blue bow.
