Answer:
h=3V/πr²
Step-by-step explanation:
Answer:
3V / (pi r^2) = h
Step-by-step explanation:
V= pi r squared h/3
Multiply each side by 3
3V = pi r^2 h /3 * 3
3V = pi r^2 h
Divide each side by pi r^2
3V / (pi r^2) = pi r^2 h /( pi r^2)
3V / (pi r^2) = h
Enter your answer in the box. Enter only the numerical value.
Step-by-step explanation:
Angle BDC is an angle inscribed in a circle. As such it intercepts TWICE as many degrees of arc as its measure
so: 2 * (3x-1.5) = 3x+9
6x -3 = 3x+9
x = 4
then the arc AC = 3x+9 = 21 degrees
OA. (3x+3)(5x-4)
OB. (3x+4)(5x-3)
C. (x+3)(15x-4)
OD. (x+4)(15x-3)
Answer:
B
Step-by-step explanation:
given the trinomial
15x² + 11x - 12
consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 15 × - 12 = - 180 and sum = + 11
the factors are + 20 and - 9 , since
+ 20 × - 9 = - 180 and + 20 - 9 = + 11
use these factors to split the x- term
15x² + 20x - 9x - 12 ( factor the first/second and third/fourth terms )
= 5x(3x + 4) - 3(3x + 4) ← factor out (3x + 4) from each term
= (3x + 4)(5x - 3)
What is the height of the trapezoid?
The area of the trapezoid is given by the formula A= (a+b)/ 2 * h
in this question a= 8, b= 10, A= 108 inches², and h is what we have to find, substitute what we have got into the formula and you will have:
108= (8+10) /2 *h
108= 9 *h
h= 108/9
h= 12 inches
