Two boats traveling the same direction leave a harbor at noon. After 3 hr they are 60 miles apart, if one boat travels twice as fast as the other find the average rate of each boat
Answer: The boat 1 moves with a speed of 40mi/h, and boat 2 moves with a speed of 20mi/h.
Step-by-step explanation:
First, we know the relation:
Distance = Speed*Time.
We can define the average rate of the boats as the average speed of the boats.
Now, we know that two boats travel in the same direction, let's define:
S₁ = speed of boat 1.
S₂ = speed of boat 2.
We know that one travels twice as fast as the other, then we can write:
S₁ = 2*S₂
We also know that after 3 hours of travel, they are 60mi apart, then if the slower one travelled a distance D in 3 hours, then:
S₂*3h = D
And the faster one will travel D + 60mi
S₁*3h = (D + 60mi)
Then we have the equations:
S₂*3h = D
S₁*3h = (D + 60mi)
We can replace S₁ by 2*S₂ to get:
S₂*3h = D
(2*S₂)*3h = (D + 60mi)
Now we have isolated D in the above equation, we can just replace it in the second equation to get:
(2*S₂)*3h = (S₂*3h + 60mi)
Now we can solve this for S₂
S₂*6h = S₂*3h + 60mi
S₂*6h - S₂*3h = 60mi
S₂*3h = 60mi
S₂ = 60mi/3h = 20mi/h
The speed of boat 2 is 20mi/h
And we knew that:
S₁ = 2*S₂
then:
S₁ = 2*(20mi/h) = 40mi/h
2 divided into 3 multiply 1

Step-by-step explanation:
The moon is about 382,500km away from Earth. This distance actually varies by about 22,500km. What are the maximum and minimum distances to the moon?
Answer:
The minimum distance to the moon is of 360,000 km and the maximum distance is of 405,000 km
Step-by-step explanation:
The maximum distance is found adding the variation.
The minimum distance is found subtracting the variation.
We have that:
Distance: 382,500 km
Variation: 22,500 km
So
Maximum distance: 382500 + 22500 = 405,000 km
Minimum distance: 382500 - 22500 = 360,000 km
The minimum distance to the moon is of 360,000 km and the maximum distance is of 405,000 km

Answer:
Each notebook costs $3.96
Step-by-step explanation:
We assume each notebook costs the same amount, the total cost is $31.68, and that is for 8 notebooks. So, we divide 31.68 by 8 and get our answer of $3.96 per notebook.

OA) 18
OB) 5
OC) 0.4
OD) 2.5
Step-by-step explanation:
it will 2.5 this is right answer option D
The common ratio of the sequence 12, 30, 75, 187.5 is 2.5 option (D) is correct.
What is a sequence?It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
We have a sequence:
12, 30, 75, 187.5
The above sequence is a geometric sequence.
The common ratio can be calculated:
r = 30/12 = 75/30
r = 2.5
Thus, the common ratio of the sequence 12, 30, 75, 187.5 is 2.5 option (D) is correct.

Answer:
We conclude that it is not a function because there are two different y-values for a single x-value.
Hence, option D is true.
Step-by-step explanation:
We know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.
In other words, we can not have duplicated inputs as there should be only 1 output for each input.
From the graph, we can determine the table such as:
x y
-2 -5
-1 3
1 -2
3 0
4 4
4 -2
It is clear that the values of x = 4, is repeated twice.
In other words, the input value x = 4 is duplicated.
We know that we can not have duplicated inputs as there should be only 1 output for each input.
Therefore, we conclude that it is not a function because there are two different y-values for a single x-value.
Hence, option D is true.

x-intercept: ( − 4 3 , 0 )
y-intercept: ( 0 , 4 )
The equation of line t is y = -2x + 9. Perpendicular to line t is line u, which passes through
the point (-10, 4). What is the equation of line u?
Write the equation in slope-intercept form. Write the numbers in the equation as proper
fractions, improper fractions, or integers.
Answer:
Equation of line u in slope-intercept form is: [tex]\mathbf{y=\frac{1}{2}x+9 }[/tex]
Step-by-step explanation:
Equation of line t : y = -2x + 9.
We need to find equation of line u, which is perpendicular to line t and passes through point (-10,4)
The equation must be in slope-intercept form.
The general equation of slope-intercept form is: [tex]y=mx+b[/tex] where m is slope and b is y-intercept
Finding Slope:
If two lines are perpendicular, their slopes are opposite i.e [tex]m=-\frac{1}{m}[/tex]
Slope of line t: y=-2x+9 we get m =-2 (Comparing with general form y=mx+b, we get m =-2)
Slope of line u: [tex]\frac{1}{2}[/tex]
So, we get Slope of line u: m= [tex]\frac{1}{2}[/tex]
Finding y-intercept:
Using slope m= [tex]\frac{1}{2}[/tex] and point(-10,4) we can find y-intercept
[tex]y=mx+b\\4=\frac{1}{2}(-10)+b\\4=-5+b\\b=4+5\\b=9[/tex]
Equation of line u:
So, equation of line u, having slope m= [tex]\frac{1}{2}[/tex] and y-intercept b=9, we get:
[tex]y=mx+b\\y=\frac{1}{2}x+9[/tex]
So, Equation of line u in slope-intercept form is: [tex]\mathbf{y=\frac{1}{2}x+9 }[/tex]

Roxie is picking out some movies to rent, and she is primarily interested in horror films and foreign films. She has narrowed down her selections to 20 horror films and 8 foreign films. How many different combinations of 3 movies can she rent if she wants at least two horror films?
Answer:
She has 2,660 combinations
Step-by-step explanation:
Here, we want to calculate the number of different combinations of 3 movies that can be rented
The condition is at least two horror movies
What this means is that she can select 2 or 3 horror movies
if two horror movies, then 1 foreign film
The combination is as follows;
20 C 2 * 8 C 1
= 190 * 8 = 1,520
If she is selecting 3 horror movies, then no foreign film will be selected
Number of ways this can be done is;
20 C 3 = 1,140
So the
number of different combinations would be;
1,140 + 1,520 = 2.660

yes

In a study, the sample is chosen by writing everyone's name on a playing card, shuffling the deck, then choosing the top 20 cards. What is the sampling method?
A. Simple Random.
B. Systematic.
C. Stratified.
D. Convenience.
Answer: A. Simple Random Sampling
Step-by-step explanation:
A simple random sampling technique could be explained as being the most basic and approach to choosing an unbiased Number of samples from a given population. This technique simply involves choosing a specified Number of samples at random (each member of the larger sample or population has equal Chance of being selected) from a larger sample or population. It does not require any sort of partitioning during selection. As in the scenario above, the deck of cards represents the large lr population from which 20 cards are to be selected, since the card has been shuffled then each card has equal Chance of being selected.

Answer:
Solving the expression: [tex]2\frac{3}{5}\div \frac{2}{3}[/tex] we get [tex]\mathbf{3\frac{9}{10}}[/tex]
Option A is correct.
Step-by-step explanation:
We need to solve the expression: [tex]2\frac{3}{5}\div \frac{2}{3}[/tex]
We need to divide both the terms.
Solving:
[tex]2\frac{3}{5}\div \frac{2}{3}[/tex]
First we will convert the mixed fraction into improper one
[tex]\frac{13}{5}\div \frac{2}{3}[/tex]
Now, we will convert division sign into multiplication, the term 2/3 is reciprocated
[tex]\frac{13}{5}\times \frac{3}{2}[/tex]
Now, multiply numerator with numerator and denominator with denominator
[tex]\frac{39}{10}[/tex]
Now, we will convert into mixed fraction
[tex]3\frac{9}{10}[/tex]
So, Solving the expression: [tex]2\frac{3}{5}\div \frac{2}{3}[/tex] we get [tex]\mathbf{3\frac{9}{10}}[/tex]
