Step-by-step explanation:
Johnny and his father go fishing at 5:00 AM. After motoring 6 km upstream, Johnny writes a letter to his friend, puts the letter in a bottle and drops it into the river. the bottle floats in the current and reaches at 7 : 40 AM the point where Johnny and his father began the trip. If the speed of the boat in still water is 9 km/h, what is the speed of the river current?
Answer:
4.5
Step-by-step explanation:
Probably too late for your RSM homework, but here is the solution:
6/(9-x) [Time they motored upstream] +6/x [Time it took the bottle to get back to the starting point] = 8/3 [Total Time]
Simplify to 54/(x(9-x))=8/3
Cross multiply: 162=(8x)(9-x)
Simplify -x^2+9x=20.25
Multiply both sides by negative one and move 20.25 to the other side. x^2-9x+20.25=0
Solve and get 4.5 :D!

Answer:
B. Decreasing; The slope of the line between points D and E is negative
Step-by-step explanation:
The graph clearly shows that the speed is decreasing between these points. This narrows down your options to either Option B or Option D. A completely vertical line has a slope of undefined. The line is not completely vertical and undefined, so Option D is incorrect. This leaves B as correct. A negative slope is a line rising right to left.

20. A grocer sells mangos for $4 per pound and apples for $3 per pound. The grocer starts with
45 pounds of mangos and 50 pounds of apples each day. The grocer's goal is to make at
combinations of mangos and apples that could be sold to meet the goal. List two possible
combinations
Describe all possible solutions
Complete question :
A grocer sells mangos for $4 per pound and apples for $3 per pound. The grocer starts with
45 pounds of mangos and 50 pounds of apples each day. The grocer's goal is to make atleast $300 each day. What combinations of mangos and apples that could be sold to meet the goal. List two possible
combinations
Answer:
m = 45 ;a = 40
m = 45 ; a = 45
Step-by-step explanation:
Mangoes, m = $4
Apples, a = $3
Total :
45 pounds of mangoes
50 pounds of apple
4m + 3a ≥ 300
If m = 45
a = 40
4(45) + 3(40)
180 + 120 = 300
If m = 45 ; a = 45
4(45) + 3(45)
180 + 135 = 315
Hence, 2 possible combination :
m = 45 ;a = 40
m = 45 ; a = 45
For all possible solutions :
4m + 3a ≥ 300

3/4(1/6x+16)=3/7(4 3/8x-21) I WILL AWORD BRILLENEST :>
Answer:
x=12
Step-by-step explanation:
Let's solve your equation step-by-step.
34(16x+16)=37((438)(x)−21)
Step 1: Simplify both sides of the equation.
18x+12=158x−9
Step 2: Subtract 15/8x from both sides.
18x+12−158x=158x−9−158x
−74x+12=−9
Step 3: Subtract 12 from both sides.
−74x+12−12=−9−12
−74x=−21
Step 4: Multiply both sides by 4/(-7).
(4−7)*(−74x)=(4−7)*(−21)
x=12
Answer:
x=12
Answer:
x = 12
Step-by-step explanation:
34(16x + 16) = 37((438)(x) − 21)
18x + 12 = 158x − 9
18x + 12 − 158x = 158x − 9 − 158x
−74x + 12 = −9
−74x + 12 −12 = −9 −12
−74x = −21
(4−7) × (−74x) = (4−7) × (−21)
x = 12

The data in the tables below were collected from first year students at a community college. The variable is "number of credit cards." If the table below is a complete probability distribution, what must be the value of T?
Number of Credit Cards (x) 0 1 2 3 4 5
Number of Students (f) 122 40 28 2 2 6
Probability P(x) 0.61 T 0.14 0.01 0.01 0.03
A. 0.4
B. 0.04
C. 0.2
D. 0.02
Solution :
It is given that P(x) is said to be complete or proper probability distribution if it satisfies the following two ways :
1. [tex]$P(x) \geq 0$[/tex]
2. [tex]$\sum_z P(x) = 1$[/tex]
Now consider,
[tex]$\sum_z P(x) = 1$[/tex]
⇒ [tex]$P(x=0)+P(x=1)+P(x=2)+P(x=3)+P(x=4)+P(x=5)=1$[/tex]
⇒ [tex]$0.61+T+0.14+0.01+0.01+0.03=1$[/tex]
⇒ [tex]$0.8+T=1$[/tex]
⇒ [tex]$T=1-0.8$[/tex]
= 0.2
Therefore, the value of T is 0.2
Thus, option (c) is correct.
Que es una ecuación cuadrática
Step-by-step explanation:
En álgebra, una ecuación cuadrática es cualquier ecuación que se puede reorganizar en forma estándar como ax ^ {2} + bx + c = 0 donde x representa una incógnita, y a, byc representan números conocidos, donde a ≠ 0. Si a = 0, entonces la ecuación es lineal, no cuadrática, ya que no hay término ax ^ 2.

Assume that a watermelon dropped from a tall building falls y = 16t ^ 2 ft in t sec. Find the watermelon's average speed during the first 6 sec of fall
A)97 ft/sec
B)48
c)96
D 192
Answer:
A.) 96 ft/sec
Step-by-step explanation:
to find the average speed of the watermelon's fall in 6 seconds, substitute 6 as t in the equation and then divide by 6: [tex]y = \frac{16(6)^{2} }{6} = 96 ft/sec[/tex]
