A salmon is swimming in a river that is flowing downstream at a speed of 2 miles per hour. The slamon can swim 12 miles upstream in the same amount of time it would take 24 miles downstream. What is the speed of the salmon in still water?
Answer:
The speed of the salmon in still water is 6 mi/h
Step-by-step explanation:
When an object moves with a speed So (So measured in still water) in a river with speed Sr:
If the object moves along the current (downstream), then the actual speed of the object will be:
S = So + Sr
If the object moves upstream, then the velocity will be:
S = So - Sr
In this case we know the speed of the river downstream is 2 mi/h
Sr = 2mi/h
And we know that the salmon can swim 12 miles upstream in the same time (T) that it can swim 24 miles downstream.
Here you need to remember the relation:
Distance = Time*Speed.
Then we know that:
24 mi = (So + 2mi/h)*T
12 mi = (So - 2mi/h)*T
Now we can take the quotient of these two equations to get:
(24mi/12mi) = ( (So + 2mi/h)*T)/((So - 2mi/h)*T)
2 = (So + 2mi/h)/(So - 2mi/h)
Let's multiply both sides by the denominator of the right part:
2*(So - 2mi/h) = (So + 2mi/h)
2*So - 4mi/h = So + 2mi/h
Now we need to isolate So, the speed of the salmon in still water:
2*So - So = 2mi/h + 4mi/h
So = 6mi/h
The speed of the salmon in still water is 6 mi/h

Answer:
600
Step-by-step explanation:
Surface area of a cube:
SA = 6a²
Given:
a = 10
Work:
SA = 6a²
SA = 6(10²)
SA = 6(100)
SA = 600
Answer:
600 squared feet
Step-by-step explanation:
This is your answer because in order to find surface area you can use the equation 6s². Which would be 6 times your side length of 10, then to the 2nd power. This is the equation because there are 6 sides in total on your cube and you are trying to find the surface area of all the sides. Since this is a cube all the sides lengths are the same, therefore you times the side length by 6 to include all of the sides. After you get your answer it is squared feet because you have a 3 dimensional shape or 3D shape. Hope this helps!!
6s²=SA
6(10)²=SA
60²=SA
600=SA
there are 650 students in a school if the number of girls is 106 more than the boys how many boys are in the school
Answer:
boys = 272
Step-by-step explanation:
b = boys
g = girls
1) write two equations with the given informations:
g + b = 650
g = b + 106
2) substitute the value of g in the first equation:
b + 106 + b = 650
3) solve the equation for b
2b = 544
b = 272
4) substitute the value in the second equation
g = 272 + 106
g = 378
girls = 378
boys = 272
On the grid draw the graph of x + 2y =7
Answer:
See attachment for graph
Step-by-step explanation:
Given
[tex]x + 2y = 7[/tex]
Required
Draw the graph
First, we identify at least 2 possible values of x and y
Let [tex]x = 1[/tex]
Solve for y
[tex]x + 2y = 7[/tex]
[tex]1 + 2y = 7[/tex]
[tex]2y = 6[/tex]
[tex]y = 3[/tex]
So, a point is: [tex](1,3)[/tex]
Let [tex]x = 3[/tex]
Solve for y
[tex]x + 2y = 7[/tex]
[tex]3 + 2y = 7[/tex]
[tex]2y = 7 -3[/tex]
[tex]2y = 4[/tex]
[tex]y = 2[/tex]
So, another point is: [tex](3,2)[/tex]
Plot [tex](1,3)[/tex] and [tex](3,2)[/tex] on the graph, then draw a straight line through both points

Look at the equation.
3+4(5−x)=19−4x+4
How many solutions does the equation have? Explain your answer.
Answer:
infinite solutions
Step-by-step explanation:
3+4(5−x)=19−4x+4
Distribute
3 +20 -4x = 19 -4x +4
Combine like terms
23 -4x = 23 -4x
Add 4x to each side
23-4x+4x = 23-4x+4x
23 =23
This is always true so there are infinite solutions

Determine the measure of the angle represented by Ø using the inverse tangent function
a 50.2°
b. 56.4°
C 39.8
d. 33.6°
ANSWER:C
Answer:
39.80°
Step-by-step explanation:
Find the diagram attached
Given the following
Opposite side = 5m
Adjacent = 6m
Required
Angle Ø
Using the SOH CAH TOA identity
Tan Ø = opposite/adjacent
Tan Ø = 5/6
Tan Ø = 0.8333
Ø = arctan(0.8333)
Ø = 39.80°
Hence the measure of the angle represented by Ø is 39.80°

g According to the U.S. department of Agriculture (USDA), 48.9% of males aged 20 to 39 years consume the recommended daily requirement of calcium. After an aggressive "Got Milk" advertising campaign, the USDA conducts a survey of 35 randomly selected males aged 20 to 39 and finds that 21 of them consume the recommended daily allowance (RDA) of calcium. At the ????=0.05level of significance, is there evidence to conclude that the percentage of males aged 20 to 39 who consume the RDA of calcium has increased?
Answer:
We can conclude that there is no sufficient evidence to conclude that the percentage of males aged 20 to 39 who consume the RDA of calcium has increased
Step-by-step explanation:
H0 : p = 0.489
H1 : p > 0.489
Phat = x/ n ; x = 21 ; n = 35
Phat = x/ n = 21 / 35 = 0.6
Test statistic :
(Phat - P0) ÷ sqrt[P0(1 - P0) /n]
1 - P0 = 1 - 0.489 = 0.511
Phat - P0 = 0.6 - 0.489 = 0.111
Test statistic = 0.111 ÷ sqrt[(0.489 * 0.511) / 35]
Test statistic = 0.111 ÷ sqrt(0.0071394)
Test statistic = 0.111 ÷ 0.0844949
Test statistic = 1.314
Pvalue from Tstatistic :
Pvalue = P(Z < 1.314) = 0.90558
α = 0.05
Pvalue > α ; Hence, we fail to reject the Null
We can conclude that there is no sufficient evidence to conclude that the percentage of males aged 20 to 39 who consume the RDA of calcium has increased

Select all the shapes that do not have perpendicular sides.
A. Square
B. Equilateral triangle
C. Rectangle
D. Right triangle
E. Acute triangle
Answer:
B and E
Step-by-step explanation:
perpendicular sides mean they will equal 90 degrees... so all rectangles and squares are perpendicular- a 90 degree triangle also is perpendicular. The Equatorial and the Acute triangle do not have 90 degree angles
