It's 60 m because 2 cm is 20 mm, and if each mm is 3 m then 20*3 is 60
Answer:
11/20
Step-by-step explanation:
22/50 is equivalent because if you multiply 50 by 2 to get 100, then multiply 22 by 2, you get 44 out of 100 (44). For 11/20 if you multiply 20 by 5 to get 100, then multiply 11 by 5, you get 55 out of 100 (55). Do the same thing for all the other ones. I hope this helps! Please mark me brainliest thanks!
Answer:
<h3>
Any of them.</h3><h2>
a ∈ R</h2>
Step-by-step explanation:
-5x - 4y = 2a 4x - 5y = 2
-4y = 5x + 2a -5y = -4x + 2
y = (5x + 2a):(-4) y = (-4x + 2):(-5)
y = -⁵/₄x - ¹/₂a y = ⁴/₅x - ²/₅
m₁ = -⁵/₄, b₁ = -¹/₂a m₂=⁴/₅, b₂= -²/₅
-⁵/₄ ≠ ⁴/₅
Different slopes means that two lines have one point of intercept (no mater what the b's are). That means that the system of linear equations has exactly one solution for any value of a.
The average of the following is 63.4
Answer:
18. 84 ft² or 18.85 ft² when rounded to the nearest tenth
Step-by-step explanation:
2πrh+2πr²
2× 3.14 × 1 × 2= 12.56
2 × 3.14 × 1² = 6.28
12.56 + 6.28 = 18.84
Have a great day :)
