Answer:
A.765 seats are not in the balcony
Step-by-step explanation:
if 15% are in the balcony then 85% are not in the balcony so..
900 * 0.85 = 765
Answer:
(3,-2)
Step-by-step explanation:
Given equations of line
3x-2y=13
2y+x+1=0
=> x = -1 -2y
Point of intersection will coordinates where both equation have same value of (x,y)
top get that we have to solve the both equations by using method of substitution of simultaneous equation.
using this value of x in 3x-2y=13, we have
3(-1-2y) -2y = 13
=> -3 -6y-2y = 13
=> -8y = 13+3 = 16
=> y = 16/-8 = -2
x = -1 - 2y = -1 -2(-2) = -1+4= 3
Thus, point of intersection of line is (3,-2)
Answer: 13 . 99 seconds
Step-by-step explanation:
The formula to find how long it will take an object to rotate through 6.9 revolutions at an angular velocity is given as :
t = 2π x number of revolutions / angular velocity
Therefore :
t = 2π x 6.9 / 3.1
t = 2 x 3.142 x 6.9 / 3.1
t = 43.3596/3.1
t = 13. 98696774194
to the nearest tenth
t = 13. 99s
8/5 or 1.6 you just need to find the rise over the run
Answer:
![x\approx7.8](https://tex.z-dn.net/?f=x%5Capprox7.8)
Step-by-step explanation:
In relation to the given angle, we are given the triangle's opposite side and hypotenuse. Therefore, we use the sine function to set up a proportion and solve for the opposite side:
![sin(\theta)=\frac{opposite}{hypotenuse}](https://tex.z-dn.net/?f=sin%28%5Ctheta%29%3D%5Cfrac%7Bopposite%7D%7Bhypotenuse%7D)
![sin(23^\circ)=\frac{x}{20}](https://tex.z-dn.net/?f=sin%2823%5E%5Ccirc%29%3D%5Cfrac%7Bx%7D%7B20%7D)
![20sin(23^\circ)=x](https://tex.z-dn.net/?f=20sin%2823%5E%5Ccirc%29%3Dx)
![x=20sin(23^\circ)](https://tex.z-dn.net/?f=x%3D20sin%2823%5E%5Ccirc%29)
![x\approx7.8](https://tex.z-dn.net/?f=x%5Capprox7.8)
Therefore, the length of the opposite side is about 7.8 units
