Answer:
12.9
Step-by-step explanation:
To solve this, you need to use the Pythagorean Theorem: a² + b² = c²
Substituting the numbers into the formula:
(9.4)² + (8.9)² = c²
(88.36) + (79.21) = c²
167.57 = c²
12.9 ≈ c
Answer:
Original size of population containing fruit files = 10 files
Rate at which population of fruit file is increasing = 22.5%
New population of fruit files having initial population of 10 files and increase rate of 22.5% is given by =
10 + 22.5 × 
= 10 + 22.5 × 
= 10+ 2.25
= 12.25 files
Answer:
42
Step-by-step explanation:
ABC + CBD = ABD
3x+33 + 5x+13 = 70
Combine like terms
8x +46 = 70
Subtract 46 from each side
8x+46-46 = 70-46
8x = 24
Divide each side by 8
8x/8 = 24/8
x=3
We want to find ABC
ABC = 3x+33 = 3*3 +33 = 9+33 = 42
