A motorboat can maintain a constant speed of 45 miles per hour relative to the water. The boat makes a trip upstream to a certain point in 34 minutes; the return trip takes 26 minutes. What is the speed of the current?
The speed of the current is _ mile(s) per hour.
Answer: Distance upstream = (34-c)(39/60) miles
--------------------------
Distance downstream = (34+c)(29/60) miles
-----------------------------------------------
Equation:
distance = rate*time
distance up = distance down
(34-c)(39/60) = (34+c)(29/60)
Multiply both sides by 60 to get:
39(34-c) = 29(34+c)
39*34 - 39c = 29*34 + 29c
68c = 340
c = 5 mph (speed of the current)Step-by-step explanation: I'm not sure if this will help you but I hope it does!

n - 6m = 8
solve for n
Hi there!

I believe your answer is:

Here’s why:
⸻⸻⸻⸻
[tex]\boxed{\text{Solving for 'm'...}}\\\\n - 6m = 8\\------------\\\rightarrow n - 6m = 8 \\\\\rightarrow n - 6m + 6m = 8 + 6m\\\\\rightarrow \boxed{n = 8 + 6m}[/tex]

a community center is trying to raise $1680 to purchase exercise equipment. the center is hoping to receive equal contributions from members of the community. write and algebraic expression to determine how much will be needed from each person if n people contribute. Then evaluate the expression for 10, 12, 14, or 16 people.
Lets find f(n) formula
[tex]\boxed{\sf f(n)=\dfrac{1680}{n}}[/tex]
Now
[tex]\\ \sf\longmapsto f(10)=\dfrac{1680}{10}=168[/tex]
[tex]\\ \sf\longmapsto f(12)=\dfrac{1680}{12}=140[/tex]
[tex]\\ \sf\longmapsto f(16)=\dfrac{1680}{16}=105[/tex]
[tex]\\ \sf\longmapsto f(14)=\dfrac{1680}{14}=120[/tex]
27 + 36
A.
9(3 + 4)
B.
(9 × 3)(9 × 4)
C.
(9 + 3)(9 + 4)
D.
9 + (3 × 4)
Answer:
It's A
Step-by-step explanation:
Using process of elimination B is wrong because even though you get 37 and 36 it multiplies them because of a lack of addition symbol. C is also wrong because it would turn out to be 12 x 13 which is larger than C so that's not it. in D 3x4 is 12 but it's added to 9 not multiplied so that's wrong which leaves you with A which is 9(3 + 4) = 63 and 27 + 36 = 63

Give the slope of a line perpendicular to AB
Answer:
m = -1
Step-by-step explanation:
Find the equation in slope intercept form [ y = mx + b ] for line AB. Find the slope using the formula [ y2-y1/x2-x1 ].
8-5/7-4
3/3
1
Find the y-intercept.
5 = 1(4) + b
5 = 4 + b
1 = b
So the equation of the line AB is y = x + 1.
The slope of a perpendicular line is the opposite reciprocal of the original line.
1 -> -1/1 -> -1

Find the inverse of the function: f(x)=−14x+4
A f−1(x)=−4x+16
B f−1(x)=−12x+2
C f−1(x)=4x+16
D f−1(x)=12x+1
Answer:
[tex]\displaystyle f^{-1}(x) = -\frac{x}{14} + \frac{2}{7}[/tex]
Step-by-step explanation:
It is neither of these. To find the inverce, interchange the variables, then solve for y:
[tex]\displaystyle x = -14y + 4 \hookrightarrow \frac{x - 4}{-14} = \frac{-14y}{-14} \\ \\ f^{-1}(x) = -\frac{x}{14} + \frac{2}{7}[/tex]

1. If ST=17 and RT=47, find RS. Use the number line below.
<-R---------------------------------------------------------------------------S---------------------------------T->
2.On a number line, suppose point E has a coordinate of 3 , and EG=6. What are the possible coordinates of point G?
3.Find the length of the segment _AB_.
<-12-------'-11'-'-10'-9'-9'-'-8'-'-7'-'-6'-'-5'-'-4'-'-3'-'-2'-'-1'-0-'1'-'2'-'3'-'4'-'5'-'6'-'7'-'8'-'9'-'10'-'11'-'12'
A is -2 and b is 4 the length is?
Please help me!
Answer:
#1Segment addition:
RS + ST = RTRS + 17 = 47RS = 47 - 17RS = 30 units#2There are two possibilities:
G is to the left of E. Then G = 3 - 6 = -3G is to the right of E. Then G = 3 + 6 = 9So possible coordinates of G are -3 or 9
#3The length of the segment is the absolute value of the difference of the end point coordinates.
AB = 4 - (-2) = 4 + 2 = 6 unitsStep-by-step explanation:
1
RS = RT - ST
RS = 47 - 17
RS = 30 cm
2.
Coordinate = 3 ± 6
If 3 + 6 = 9
If 3 - 6 = -3
3
AB = 4 - (-2)
AB = 6
Her jump rope Ella can make 17 jumps in 15 second.at this rate how make jumps can she make in20 minute?
Answer:
1360
Step-by-step explanation:
there are 1200 seconds in 20 minutes. if Ella can do 17 jumps in 15 seconds, you would divide 1200 by 15 (which equals 80) because that would be the number of 15 seconds in 20 minutes. then you would divide 80 by 17, which gives you your final answer of 1360 jumps in 20 minutes.
