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!
Find the compound interest of N5000 for 2 years at 5% per annum
For finding the compound Interest first we need to get the amount and then subtract the value of principal from amount
Calculation Begins
Principal = 5000, Rate of Interest = 5%, Time = 2 yrs
[tex] \looparrowright \sf{A = P(1 + \frac{r}{100} )^{n} } \\ \\ \looparrowright \frak{ {\sf A} = 5000(1 + \frac{5}{100} )^{2} } \\ \\ \looparrowright \frak{ {\sf A} = 5000(1 + \frac{1}{20} )^{2} } \\ \\ \looparrowright \frak{ {\sf A} = 5000( \frac{21}{20})^{2} } \\ \\ \looparrowright \frak{ {\sf A} =5000 \times \frac{441}{400}} \\ \\ \looparrowright \frak{ {\sf A} = 12.5 \times 441} \\ \\\looparrowright \frak{ {\sf A} = 5152.5} [/tex]
Hence the amount is 5152.5
Compound Interest = Amount - Principal
= 5152.5 - 5000 = 152.5
152.5 is the Compound Interest27 + 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
pls answer correctly!

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

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]

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.

The fraction models below represent two fractions of the same whole. How much of the Fraction 3 over 8 is in the Fraction 1 over 4 ? Two rectangles of the same size are drawn side by side touching each other. The first rectangle is divided into 8 portions of equal size. Three of these are shaded. The shaded portion alone is labeled as 3 over 8. The second rectangle is divided into 4 portions of equal size. One portion is shaded. The shaded portion alone is labeled 1 over 4.
9514 1404 393
Answer:
2/3
Step-by-step explanation:
You can see from the diagram that the shaded 1/4 of the second rectangle has the same dimensions as 2 of the 3 shaded parts of the first rectangle.
2/3 of 3/8 is in 1/4
