The mean to your problem is 87.5
Susanne is 16 years old.
b = Bob's age
s = Susanne's age
d = Dakota's age
Bob's age is 4 times greater than Susanne's age:
b = 4s
Dakota is three years younger than Susanne:
d = s - 3
The sum of Bob's, Susanne's, and Dakota's ages is 93:
b + s + d = 93
solve these equations:
b = 4s
d = s - 3
b + s + d = 93
and get:
b = 64 years
s = 16 years
(remember that s = Susanne)
d = 13 years
Given:
a ladder with three steps.
top step is 45° angle.
45° / 3 steps = 15°
So, top step is 45°. Middle step is 30°. Bottom step is 15°. Ground is 0°
The photographer would shout on the bottom step at an angle of 15°.
Use the slope formula<span> to find the slope. Use the slope (that you found in the step above) and one of the </span>points<span> to find the y-intercept. (Using y = mx+b, substitute x, y, and the slope (m) and </span>solve<span> the</span>equation<span> for b.) </span>Write<span> the </span>equation<span> in slope intercept</span>form<span> using the slope and y-intercept</span>
Hello,
Just for the fun, it's been a long time for that.
