In a hydroelectricity production, water falls from a dam into a turbine wheel 49 m below. What is the velocity of water at the turbine?
A) 0 m/s
B) 15.5 m/s
C) 31 m/s
D) 46.5 m/s
Answer:
C: 31 m/s
Step-by-step explanation:
It falls from a dam.
Thus;
Initial velocity; u = 0 m/s
Height; h = 49 m
Acceleration due to gravity is 9.8 m/s²
To solve for the final velocity this, we will use Newton's third equation of motion;
v² = u² + 2gh
v² = 0² + 2(9.8 × 49)
v = √960.5
v ≈ 31 m/s

A water pipe takes 45 minutes to fill a
tank. How many water tanks it would fill in
6 hours.
Math
Answer:
It would fill 8 tanks
Step-by-step explanation:
45minutes = 3/4 of an hour
It would fill 6/(3/4) tanks in 6 hours
6/(3/4) = 6/3*4 = 2*4 = 8
Define a cubic polynomial and a binomial use only one variable in each). Show how to use the Vertical Method to multiply these two.pls Quick I do not wanna FAIL
Cubic polynomial
[tex] {x}^{3} + {2x}^{2} - 5x - 10[/tex]
Binomial
[tex]2x - 3[/tex]
By vertical method of multiplication we get,
[tex] {2x}^{4} + {x}^{3} - {16x}^{2} - 5x + 30[/tex]
3) 8x + 6y = 10 -8x + 6y = 2 Which statement about the system of equations is true? A) The system has exactly 1 solution B) The system has many solutions C) The system has no solution D) The system has exactly 2 solutions 3 3
Answer:
A. Exactly one solution
Step-by-step explanation:
8x+6y=10
-8x+6y=2
0+12y=12 added two equations together
12y=12
y=1
solve for x
8x+6y=10
8x+6(1)=10
8x=4
x=1/2
A new laptop is on sale for $550 dollars. To pay for it you place it on your credit card which charges 12% percent interest each month
The interest amount charged on a new laptop is on sale for $550 dollars is $66.
Given that, a new laptop is on sale for $550 dollars.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Now, 12% of 550
= 12/100 ×550
= 0.12 ×550
= $66
So, interest is $66
Therefore, the interest amount charged on a new laptop is on sale for $550 dollars is $66.

Is this correct???????????!!!!please gelppp
Answer:
Step-by-step explanation: it looks right to me but who knows
Answer:
Yes
Step-by-step explanation:
The line intersects the y axis at point 4 (y > 3/2 x + 4), and for every 2 squares to the right it goes 3 squares up (y > 3/2 x + 4). Also, it's the > sign, which is correct when it goes in that direction.
What is the slope of the line given by the equation y = 12x?
Answer:
up 12 over 1
Step-by-step explanation:
Answer:
12
Step-by-step explanation:
12 is before x and the b or y-intercept is 0

Ten deer were introduced into a protected preserve. Their expected population doubles each year. Which function represents the same relationship?
Answer:
y(t)= 10 (2)^t
Step-by-step explanation:
If t is the number of years given then the expected number can be found by
y(t)= 10 (2)^t
where t takes the value 0,1,2,3, and so on.
Putting t= 0
y(t)= 10 (2)^t
y(0)= 10 (2)^0
y(0)= 10 For the start the number of deer are 10.
Putting t= 1
y(t)= 10 (2)^t
y(1)= 10 (2)^1
y(1)= 20 After 1 year it has doubled to 20
Putting t= 2
y(t)= 10 (2)^t
y(2)= 10 (2)^2
y(2)= 40 After 2 years it has again doubled to 40
Putting t= 3
y(t)= 10 (2)^t
y(3)= 10 (2)^3
y(3)= 80 After 3 years it has again doubled to 80

Answer:
k = 5.25
Step-by-step explanation:
Given y varies directly with x then the equation relating them is
y = kx ← k is the constant of proportionality
To find k use the condition y = 84 and x = 16 , then
84 = 16k ( divide both sides by 16 )
5.25 = k

You have $20 to spend for cupcakes. If each cupcake costs $4, write and solve an inequality to show the maximum number of cupcakes you can buy.
Work out the value of
x
The diagram is not drawn to scale.
The shape is a pentagon.
The interior angles of a pentagon always add up to 540°.
When you add up all the labeled angles in the picture, you get (16x + 12).
16x + 12 = 540
16x = 528
X = 33
Step-by-step explanation:
4x-25+3x+25+3x+15+4×+2x-3=360
4x+3x+3x+4x+2x-25+25+15-2=360
16x +12=360
16x=360-12
16×÷16=348÷16

WHAT IS THE MEDIAN I WILL GIVE BRAINIEST
Answer:
5 is the median
Step-by-step explanation:
By crossing out the points on each side one by one, you could find that 5 is the median.
The median income for a sample of people from Chicago is about $60,000 and the
median income for a sample of people from Kansas City is about $46,000, but
researchers have determined there is not a meaningful difference in the medians.
Explain why the researchers might be correct.
Answer:
106,000 is the answer help me with my answer to
Answer:
The medians differ by $14,000, but if the IQR is larger than about $7,000, there will not be a meaningful difference between the median salaries in the two cities.
