You do length times width times you get your area. (I think)
Answer: the equation is 6+5x=3x+10.
Step-by-step explanation:
to find the number
add 5x+3x
then add 10+6
8x=16
divide by 2 each side.
x=2
Answer:
The correct option is B.
Step-by-step explanation:
It is given that the correlation coefficient between two variables is -0.95.
Correlation coefficient between two variables is denotes by ρ. The value of ρ is leis between -1 to 1.
If
, then it represent perfect negative correlation.
If
, then it represent perfect positive correlation.
If
, then it represent no relationship between the variables.
Since the -0.95 is near to the value -1, therefore we can say that there is a strong negative association between the variables. Option B is correct.
Answer:
The ladder must be placed at a distance of 33.2 feet from the bottom of the building
Step-by-step explanation:
From what we have here, we are looking at a right angled triangle with the hypotenuse which is the length of the ladder
The height of the child is 50 feet from ground level
So we need to get the third side of the triangle
We can get this by considering the use of Pythagoras’ theorem
This will give us the length of the third side of the triangle
From Pythagoras’ the square of the hypotenuse is equal the sum of the squares of the two other sides
Let the unknown side be x
Thus;
60^2 = 50^2 + x^2
x^2 = 60^2 - 50^2
x^2 = (60-50)(60+50)
x^2 = (10)(110)
x^2 = 1100
x = square root of 1100
x = 33.166
To the nearest tenth, this is 33.2 feet
Check the picture below.
so is really just a cylinder with a cone on the side, notice, since the diameter of the base is 4, the radius is half that then.
so we just simply get the volume of the cylinder, and the cone, and sum them up
