Answer:
h=(3v)/(pi r^2)
Step-by-step explanation:
you simply have to move everything to one side.
Answer:
h = [tex]\frac{3V}{\pi r^2}[/tex]
Step-by-step explanation:
Given
V = [tex]\frac{1}{3}[/tex]πr²h ( multiply both sides by 3 to clear the fraction )
3V = πr²h ( isolate h by dividing both sides by πr² )
[tex]\frac{3V}{\pi r^2}[/tex] = h
Rico bicycles at an average speed of 15.5 miles per hour. What distance will Rico bicycle in 4.5 hours? Rico will bicycle ________ miles in 4.5 hours.
Answer:
69.75 miles
Step-by-step explanation:
15.5 miles = 1 hour
x miles = 4.5 hours
Cross product
15.5 * 4.5 = 1 * x
69.75 = x
x = 69.75 miles

Subtract (2x - 2y) from the sum of (10x - 2y) and (-3y)
Subtract (2x - 2y) from the sum of (10x - 2y) and (-3y) is 8x -3y.
What is subtraction?Subtraction is a mathematic operation. Which is used to remove terms or objects in an expression.
The sum of (10x - 2y) and (-3y).
(10x - 2y) + (-3y),
= 10x -2y -3y
= 10x -5y
Subtract (2x - 2y) from the sum of (10x - 2y) and (-3y),
= 10x -5y - (2x - 2y)
= 8x -3y
Therefore, the expression is 8x -3y.

Find the value of X (please answer i need alot of help)
I need the answers for both a and b so thats why 61 points are up for grab
Answer:
Step-by-step explanation:
From the picture attached,
a). Triangle in the figure is ΔBCF
b). Since, [tex]L_1[/tex] and [tex]L_2[/tex] are the parallel lines and m is a transversal line,
m∠FBC = m∠BFG [Alternate interior angles]
Since, [tex]L_1[/tex] and [tex]L_2[/tex] are the parallel lines and n is a transversal line,
m∠BCF = m∠CFE [Alternate interior angles]
By triangle sum theorem in ΔBCF
m∠FBC + m∠BCF + m∠BFC = 180°
From the properties given above,
m∠BFG + m∠CFE + m∠BFC = 180°
m∠GFE = 180°
Therefore, angle GFE is the straight angle that will be useful in proving that the sum of the measures of the interior angles of the triangle is 180°.

Let x denote the number of broken pencils in a randomly selected 50-count box from a local office supply store. The variable x has the
following probability distribution:
a)
0.82; if we were to select many boxes of pencils randomly, the number of broken pencils would typically vary about 0.82 from the
mean
b)
0.31; if we were to select many boxes of pencils randomly, we would expect about 0.31, on average, to contain broken pencils
c)
0.65; if we were to select many boxes of pencils randomly, the number of broken pencils would typically vary about 0.65 from the
mean
d)
0.52; if we were to select many boxes of pencils randomly, we would expect about 0.52 to have no broken pencils
e)0.13; if we were to select many boxes of pencils randomly, we would expect about 0.13, on average, to contain broken pencils

Need help ASAP fine the value of x. Round to the nearest tenth x=
Answer:
x = 13.5
Step-by-step explanation:
To find x, we use the sine rule
For the sine rule,
the ratio of the sides to the sine of the angle facing the side is equal for all the sides of the triangle
Thus,
x/sin 34 = 11/ sin 27
x = 11 sin 34/sin 27
x = 13.5

Find the area of each figure. Use 3.14 for pi.
so you know the how to find the area for a saquare A=a*b first we have to find the area for a circle 10*10=100 A=100cm (2) is the area for our circle
so we have half of the circle so formula for that is A=(πr(2))/2 we know the radius is 5 A=3.14*25/2
A=78.5/2 reason why we are dividing by this number to 2 because we have half of the circle A=39.25 then add two areas together A=100+39.25=....
A market research survey has 15 questions and will be sent to 500 people. What is the total cost to conduct the survey if it has a $1,000 base fee plus $5 per question and $2 per person surveyed?
Answer:
Total cost to conduct survey = $2075
Step-by-step explanation:
Given that:
Number of questions on survey = 15
Number of people = 500
Base fee = $1000
Per question charge = $5
Per person surveyed = $2
Let,
q be the number of questions
p be the number of people
Total cost = Base fee + 5q + 2p
Total cost = 1000 + 5(15) + 2(500)
Total cost = 1000 + 75 + 1000
Total cost = $2075
Hence,
Total cost to conduct survey = $2075

what is y=6x^2 +96x +388 in vertex form?
please show work
Answer:
y = 6(x + 8)² + 4
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Using the method of completing the square.
y = 6x² + 96x + 388
The coefficient of the x² term must be 1, so
factor out 6 from 6x² + 96x
y = 6(x² + 16x ) + 388
To complete the square
add/subtract (half the coefficient of the x- term)² to x² + 16x
y = 6(x² + 2(8)x + 64 - 64) + 388
= 6(x + 8)² - 384 + 388
y = 6(x + 8)² + 4 ← in vertex form
