ITS 4 BECAUSE 2 then add 2 then you get 4 you have 2 apples and you add two more you have 4
The area of a square floor on a scale drawing is 81 square centimeters, and the scale drawing is 1 centimeter:2 ft.
so the original area is
A = 81 sq cm ( 2 ft / 1 cm)^2a = 324 sq ft
so the ratio of the ratio the area in the drawing to the actual area is:
r = 81 sq cm / 324 sq ftr = 1 sq cm / 4 sq ft1 sq cm : 4 sq ft
Answer:
A=60
Step-by-step explanation:
Add 28+20+12
A=60
<span>Let's called the train that traveled south train A, and the train that traveled east train B
After 3 hours, train A is 180 miles South
and Train B is 150 miles East
Using Pythagoras, distance between is sqrt(180^2 + 150^2)
30 sqrt(6^2 + 5^2) = 30sqrt(36 + 25) = 30sqrt 61 = 234.307 miles</span>
