Answer:
6.76
Step-by-step explanation:
applying pythogorem theorem
a^2+b^2=c^2
5^2+b^2=13^2
25+b^2=169
b^2=169/25
b^2=6.76^2
b=6.76
Answer:
Solving the system of equations:
x: 1
y: 2
Step-by-step explanation:
Plug it in to see if it is right, to make sure of course. Better to be safe than sorry.
Let
x-----------> the number of kids
y----------> the number of adults
we know that
2.5x+6y=$7150---------> equation 1
x=2y-------------> equation 2
substitute 2 in 1
2.5*[2y]+6y=7150-----> 5y+6y=7150----> 11y=7150-----> y=650
x=2y----> x=2*650----> 1300
the answer is
the number of kids is 1300
Answer:
Slope = 5.
y-int = (0, -2).
Step-by-step explanation:
y = 5x - 2
The slope intercept form is
y = mx + b where m = the slope and b = the y-intercept.
So here, the slope = 5 and the y-intercept is where y = -2. That is the point (0, -2).
30 = 100%
1 = 100/30 = 10/3 %
24 = 10/3 x 24 = 80%
Answer: 80%
