Fran swims at a speed of 2.9 km/h in still water. The Lazy River flows at a speed of 0.1 km/h. How long will it take Fran to swim 9 km upstream?
It will take Fran h to swim 9 km upstream.
Answer:
Fran's upstream speed (against the current):
2.9 km/hr - 0.1 km/hr = 2.8 km/hr
Fran's downstream speed (with the current):
2.9 km/hr + 0.1 km/hr = 3.0 km/hr
Using the distance formula for calculating time:
rate x time = distance
time = distance / rate
Fran's upstream time = 9 / 2.8 = 3.21 hrs
Fran's downstream time = 9 / 3.0 = 3.0 hrs

HELP RIGHT NOW PLEASE!!!!!!!!!!!! What is the value of x?
Answer:
x = 34
Step-by-step explanation:
Add together all three angles because together they equal 180 degrees
x + 12 + x + 100 = 180 Combine like terms
2x + 112 = 180
- 112 - 112 Subtract 112 from both sides
2x = 68 Divide both sides by 2
x = 34

Step-by-step explanation:
The expression is:
[tex]2(3y+6)-3(-4-y)[/tex]
In order to simplify the expression first multiply the numbers inside the parenthesis by the factor:
[tex]6y+12+12+3y[/tex]
[tex]6y+24+3y[/tex]
[tex]9y+24[/tex]
Another alternative is:

For one month, Terry recorded the time at which her school bus arrived. She organized her results in a frequency table. Find the experimental probability that the bus will arrive between 8:20 and 8:24.
Answer:
Experimental Probability is found:
P = 11/24
Step-by-step explanation:
Experimental Probability can be defined as the ration of the number of times (frequency) a desirable event has occurred, to the Total number of time (total frequency) the activity has been performed.
Probability = P = Frequency of an event / Total Frequency
To find the total frequency, we add all three of the given frequencies:
Total Frequency = 10 + 11 + 3
Total Frequency = 24
Frequency of the event (times bus arrived between 8:20 to 8:24) = 11
So, experimental probabilty is found as:
P = 11/24

Which sets are best represented by the Venn diagram G = {odd numbers)
H = {even numbers)
1 = {prime numbers
B. G = {a,b,c}
H = {d, e, f}
1 = {a, d, g}
C. G= {1, 2, 3
H = {2, 4, 9}
1 = {4, 5, 6)
D. G={a, -13,7}
H={-13, -15, s}
1 = {s, a, 23}
Answer:
option C.
G = {1, 2, 3}
H = {2, 4, 9}
1 = {4, 5, 6}
Step-by-step explanation:
From the diagram given above, we obtained the following information:
1. G Intercession H (G n H) has members i.e (G n H) is not epmty
G n H ≠ empty.
2. H Intercession I (H n I) has members i.e (H n I) is not empty
H n I ≠ empty.
3. G Intercession I (G n I) is empty i.e
G n I = empty.
Please note: Intercession of sets talks about elements or members common to the sets.
With the above information, we can suggest the answer to the question as follow:
For option A:
G = {odd numbers} = {1, 3, 5, 7,.. }
H = {even numbers} = {2, 4, 6, 8,.. }
I = {prime numbers} = {2, 3, 5, 7,...}
Therefore:
G n H = {} = empty
H n I = {2}
G n I = {3, 5, 7,..}
For option B:
G = {a,b,c}
H = {d, e, f}
I = {a, d, g}
Therefore:
G n H = {} = empty
H n I = {d}
G n I = {a}
For option C:
G = {1, 2, 3}
H = {2, 4, 9}
I = {4, 5, 6}
Therefore:
G n H = {2}
H n I = {4}
G n I = {} = empty
For option D:
G = {a, -13, 7}
H = {-13, -15, s}
I = {s, a, 23}
Therefore:
G n H = {-13}
H n I = {s}
G n I = {a}
From the above illustrations, only option C is correct.

What is the measure of ∠E? Enter the correct value. Do not enter the degree symbol.
Answer:
To find < E we use tan
tan E = opposite / adjacent
DF is the opposite
EF is the adjacent
DF = 11
EF = 11
tan E = 11/11
tan E = 1
E = 45
Hope this helps
Answer:
45 degrees
Step-by-step explanation:
Since this triangle is isosceles, we know that the other angles, D and E, are both 45 degrees because of the sum of interior angles of a triangle always equaling 180 degrees.

Angle θ is in standard position. If tan θ < 0 and cos θ = − 4/5 , find sin θ .
Answer:
The value found is.
sin θ = 0.6
Step-by-step explanation:
We know that the value of cosθ is given -4/5
cosθ = -4/5
First, lets finds the angle θ by taking inverse of cosine of -4/5
θ = cos⁻¹ (-4/5)
θ = 143.13°
Substitute the found θ = 143.13° it in tanθ to see if satisfies the equation tanθ < 0:
tanθ < 0
tan(143.13°) < 0
-0.75 < 0
Hence the equation is satisfied.
Which means that θ is equals to 143.13° and can be used to find sinθ
sinθ = sin 143.13°
sin 143.13° = 0.6

PLEASE HURRY Find the sum of the first 10 terms in the series: -3, 9, -27, 81... a. -14763 c. 44286 b. 4920 d. 59049
Answer:
C.
Step-by-step explanation:
First find the pattern. The pattern is you multiply the number before by -3.
Just start with x as the first number.
x, -3x, 9x, -27x, 81x, -243x, 729x, -2187x, 6561x, -19683x
Add them all up: -14762
Now multiply by -3:
44286
The required sum of the first 10 terms in the series is given as 44286. Option C is correct.
Given that,
The sum of the first 10 terms in the series: -3, 9, -27, 81... is to be determined.
Geometric progression is a sequence of series whose ratio with adjacent values remains the same.
here,
For Geometric progression,
a = -3
r = 9/-3 = -3
The sum of the 10 terms of GP is given as,
S = a[rⁿ - 1] / [r - 1]
Substitute the value in the above equation,
S = -3[{-3}¹⁰ - 1]/[-3-1]
S = 3/4 [3¹⁰ - 1]
S = 44286
Thus, the required sum of the first 10 terms in the series is given as 44286. Option C is correct.
