4/15, 5/9 and 3/5.
Hope this helps! :)
Answer:
11) 49 in.²
13) 4.515 m²
Step-by-step explanation:
11) area of square = (side)²
area = (7 in.)² = 7 in. × 7 in. = 49 in.²
13) area of triangle = base × height/2
area = 4.3 m × 2.1 m / 2 = 4.515 m²
To find y, when x = 2
we set up another ratio y/2
By the definition both ratios are equal 12/-15 = y/2
Multiple to each side by 2.
12*2/-15 = 2y/2
8/-5 = y
y = -8/5
