(1/4)x = 2
x = 8 x 3 = 24 feet long
(1/4)x = 1
x = 4 x 3 = 12 feet wide
24ft x 12ft = 288ft^2
No,
although all the sides are the same length on an equilateral triangle the height is calculated by a straight perpendicular line at the mid point of the base.
The sides are not perpendicular with the base and are angled outwards
111km
the ratio is 1:15 so you do 7.4×15
20/x+11=10/x+3
20(x+3)=10(x+11)
20x + 60 = 10x + 110
10x = 50
x = 5
Answer:
B & C
Step-by-step explanation:
2:9 can also be written as 2/9
A. 9:2 is just the reciprocal of 2:9 so it is not equivalent to it
B. 18:81 is 2×9:9×9 meaning that is equivalent to 2:9
C: 12:54 is 2×6: 9×6 so it is equivalent to 2:9
Since the two correct answers have already been found, I don't need to explain more.
Hope this helped!!!
