First use Pythagoras theorem to find the length |DE|. Next use the sine rule
1188 = π<em>r</em>²<em>h</em>
For the formula to solve for <em>h, </em>you have to change the equation to:
<em>h </em>= 1188/π<em>r</em>²
which is just moving h to the left side of the equation, and moving v(in this case 1188) to the right side.
because <em>h </em>was multiplied to the original equation, switching sides in an equation makes its replacement(1188) into a devision. (if you move a number across the = sign, the number will become the opposite of itself.)
Since you don't know the radius, you can't simplify this equation.
The answer is <em>h </em>= 1188/π<em>r</em>²
Answer: the system of equations are
3x + 2y = 170
4x + 6y = 360
Step-by-step explanation:
Let x represent the price of a child's ticket in dollars.
Let y represent the price of an adult's ticket in dollars.
The Brown family paid 170 for 3 children and 2 adults. This would be expressed as
3x + 2y = 170
The Peckham family paid 360 for 4 children and 6 adults. This would be expressed as
4x + 6y = 360
Answer: It would be 13.0 hours.
Step-by-step explanation: It would be 13.0 hours because $11.00 times 13.0hours is $143.00 so just do 11*13 and you get 143.
