To find the slope(m), use the slope formula:
And plug in the two points
(3, -6) = (x₁, y₁)
(11, 0) = (x₂, y₂)
(two negative signs cancel each other out and become positive)
Simplify the fraction
A. It represents the amount of water currently in the bottle
b.
Answer:
112.81 m.
Step-by-step explanation:
The pole and the tower and their shadows form 2 similar triangles so their corresponding sides are in the smae ratio.
Therefore we have the relation:
1.21 / 48.75 = 2.8 / x where x is the height of the tower.
Cross multiplying:
x = 2.8 * 48.75 / 1.21
= 112.81 m
Calculate them separately and add them together.
The formula for the area of a triangle is
is the area of the triangle.
The area of a rectangle is
is the area of the rectangle.
is the total area.
Answer:
6.50
Step-by-step explanation:
You have to add/multiply 2.50 by 3 to get the total cost of the cards. 2.50*3=7.5. then, you need to add/multiply 3.00 by 2 to get 6. 7.5+6= 13.5. 20-13.5=6.50.
the change was $6.50
