Step-by-step explanation:
The equation of a line in slope - intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 5) and (x₂, y₂ ) = (4, 8)
m =
= 
Note the line crosses the y- axis at (0, 5) ⇒ c = 5
y =
x + 5 ← equation in slope- intercept form
Answer:
40 exhibits dose the aquarium have.
Second model represent the problem.
Step-by-step explanation:
let number of exhibits dose the aquarium have = x
According to given condition;
90% of x = 36
(90/100) x = 36
x = (36×100)/90
x = 40
40 exhibits dose the aquarium have.
Second model represent the problem.
Answer:
pythagorean theorem is a^2+B^2=c^2
plug in (3)^2+(4)^2=(5)^2
9+16=25
