Three boats are at sea Jenny one(j1) Jenny two(j2) and Jenny three (j3). The crew of j1 can see both j2 and j3 (they create a triangle). The angle created at j1 is 45°. If the distance between j1 and j2 is 2.7 miles and the distance between j2 and j3 is 4.2 miles, what is the distance between j1 and j3 to the nearest tenth of a mile?
Answers
Answer:
Step-by-step explanation:
You know an angle, the side opposite the angle, and the side between them.
Use the Law of Sines.
j3 = arcsin(2.7sin(j1)/4.2) ≅ 27.0°
j2 = 180°-j1-j3 ≅ 108.0°
x = distance from j1 to j2
= 4.2sin(j2)/sin(j1)
≅ 5.7 miles

Let's roll two dice and find the probability of rolling a certain sum. Is this a simple or compound event?
Two dice - Red and Blue
Recall that a simple event has one and only one outcome of interest. In this example, we are rolling two dice, but we are only interested in one outcome, the sum of the two dice. This is a simple event.
What is the probability of:
Rolling a sum of 1?
Rolling a sum of 3?
Rolling a sum of 12?
Rolling a sum of 7?
Since we are rolling a pair of dice and looking for the sum, the sample space is a little more complicated than rolling one die. The chart below will help us determine the possible outcomes. The top row indicates the numbers on the sides of the blue die and the first column represents the number on the sides of the red die. The white area indicates the sum of the numbers in the row and column.

A point is plotted on a coordinate grid at (-3, 4). How far is the point from point (0, 0)?
Answers
The point at (-3, 4) is at a distance of 5 units from the point (0, 0).
How far is the point from (0, 0)?For two points (x₁, y₁) and (x₂, y₂), the distance between them is given by the formula:
distance = √( (x₁ - x₂)² + (y₁ - y₂)²)
In this case, we want to get the distance between (-3, 4) and (0, 0), using the above formula we will see that the distance is:
distance = √( (-3 - 0)² + (4 - 0)²) = √25 = 5
The distance is 5 units.

Answers
Answer: 60
Given,
Ratio of Girls:Boys (G:B) = 7:5
Also, number of girls = 10 + number of boys
G = 10 + B
G/B = 7/5
(10+B)/B = 7/5
50 + 5 B = 7B
2B = 50
B = 25
G = 10 + B = 35..
A. Number of girls = 35
B. Number of boys = 25
C. Total students = 60
OR
Given G:B = 7:5
Difference between number of girls and boys = 10
Ratio difference = 2 parts (7-5=2)
2 parts===10
1 part ===5
7 parts(gilrs) == 7*5 = 35
5 parts (boys) == 5*5 =25

Answer:
$15.00 per day and $0.22 per mile.
Step-by-step explanation:
To determine the daily fee and mileage fee charged by Best Rentals, we can set up a system of equations based on the given information.
Let's assume the daily fee is represented by "d" and the mileage fee is represented by "m."
For Mateo:
3d + 300m = 111.00
For Dara:
5d + 600m = 207.00
Now we can solve this system of equations to find the values of "d" and "m."
Multiplying the first equation by 2 to eliminate "m," we get:
6d + 600m = 222.00
Subtracting the second equation from this equation, we have:
(6d + 600m) - (5d + 600m) = 222.00 - 207.00
d = 15.00
Substituting the value of "d" into the first equation, we can solve for "m":
3(15.00) + 300m = 111.00
45.00 + 300m = 111.00
300m = 111.00 - 45.00
300m = 66.00
m = 0.22
Therefore, Best Rentals charges $15.00 per day and $0.22 per mile.

The union of sets A and B, indicated AUB, is the set of all components that have a place to set A or set B or both, inside the setting of the given all-inclusive set.
In set hypothesis, the union of two sets A and B, indicated by A ∪ B, is the set of all components that have a place to either set A or set B or to both. The widespread set, signified by U, is the set that contains all the components beneath thought.
In this manner, to break down A ∪ B utilizing the widespread set, we ought to know what components have a place in the all-inclusive set, as well as which components have a place to set A and set B.
Let's say that U is the all-inclusive set, and A and B are subsets of U. At that point able to break down A ∪ B utilizing the taking after equation:
A ∪ B = {x | x ∈ A or x ∈ B}
In other words, A ∪ B is the set of all components x that have a place to A or B (or both).

Answers
The number that can complete the equation 5y + 2(3y − 1) = ⬜y − (y + 2) is
5y + 2(3y − 1) = 12 y − (y + 2)
How to find the number that can complete the equationThe number that can complete the equation is computed by simplifying the equation at the left hand side of the equality sign and comparing with the right side of the equality side
The comparison will show the number that can fit in the blank
Simplifying the equation at the left hand side of the equation
= 5y + 2(3y − 1)
= 5y + 6y − 2
= 11y - 2
Simplifying the equation at the right hand side of the equation
= ⬜y − (y + 2)
let x represent the missing number
= xy − (y + 2)
= xy − y - 2
comparing both equations
11y - 2 = xy − y - 2
11y = xy − y
11y + y = xy
12y = xy
x = 12
The missing value = 12

If there are 64 players and 3 rounds, 32 will get out in the first round. 16 will get out in the second, and 8 will get out on the third. Thus, the answer is 64-(32+16+8) or just simply 8.
Pankaj is a Biomedical Engineering student. He plans to deposit $600 that he earned as stipend, in
a bank account at 3% rate of interest compounded weekly for no more than 2 years. The total
amount of the money, A, that Pankaj will get back, is a function of time, t. Which is a reasonable
domain of the money that he may accumulate?
Answers
The correct answer is A: 600 <= money <= 2822.4.
This represents the range of possible values that Pankaj's accumulated money could fall into, given the specified conditions of the 3% interest rate compounded weekly for a maximum of 2 years. The lower bound, 600, represents the initial deposit amount, while the upper bound, 2822.4, represents the maximum amount of money Pankaj could earn after 2 years, assuming that interest is compounded every week.
A crew will arrive in one week and begin filming a city for a movie. The mayor is desperate to clean the city streets before filming begins. Two teams are available, one that requires 700 hours and one that requires 600 hours. If the teams work together, how long will it take to clean all of the streets? Is this enough time before the cameras begin rolling?
Answers
Step-by-step explanation:
1 week = 7 days of 24 hours each = 7×24 = 168 hours.
the first team can do 1/700 of the total work per hour.
the second team can do 1/600 if the total work per hour.
if they work together, then 1/700 + 1/600 of the total work can be done per hour.
to add these 2 fractions we need to bring them to the same denominator. and that would be 4200 (LCM of 700 and 600).
1/700 + 1/600 = 6/4200 + 7/4200 = 13/4200
so, together, they can do 13/4200 if the total job in 1 hour.
how many hours will they need together to finish the job ?
well, how often does 13 fit into 4200 (as 4200/4200 is the complete job) ?
4200 / 13 = 323.0769231... hours
so, it will still take a little bit over 323 hours to clean all the streets.
but there are only 168 hours until the film crew starts.
so, no, there is not enough time.

A child has a bottle full of pennies, nickels,dimes and quarters. There are twice as many quarters as pennies, four times as many nickels as pennies, and five times as many dimes as nickels. How many more dimes does the child have than quarters?
Answers
Answer:19x
Step-by-step explanation:
Take x as the value of pennies
If there are twice as many quarters as pennies then the explanation should be
Pennies =x
Quarters =2x
If there are 4 times as many nickels as pennies then the explanation is
Pennies =x
Nickels =4x
If there are 5 times as many dimes as nickels then the explanation is
Nickels =4x
Dimes=20x
So the values of them all is
Pennies =x
Nickels =4x
Dimes =20x
Quarters =2x
So to get how many more dimes does the child have than quarters you subtract
20x-2x=19x
The Number of dimes the child has more than quarters is; 10 times more.
Let number of pennies be P
Since he has twice as many quarters as pennies, then;
Number of quarters; Q = 2P
Four times as many nickels as pennies. Then;
Number of nickels; N = 4P
five times as many dimes as nickels. Then;
Number of dimes; D = 5N = 5(4P) = 20P
Since number of quarters = 2P
And number of dimes = 20P
Then;
Number of dimes the child has more than quarters is; 20P/2P = 10
Thus, the child has ten times as many dimes as quarters
