25/100=30/x x=120 (30+70y)/(120+100y)=50/100 100y=?
Answer: D, All of the above
Step-by-step explanation:
Answer:
7.17 cm
Step-by-step explanation:
If the width is x, the length is twice this = 2x
And
Perimeter = 2 (W + L)
so
Perimeter = 2 ( x + 2x)
Perimeter = 2 (3x)
Perimeter = 6x
43 = 2 ( x + 2x )
43= 2 ( 3x)
43 = 6x
= 7.17 cm
Hope this helps i'm pretty sure this is how you do it :-)
Answer:
- f(2) = 0.5(2) +3.4
- f(3.5) = 0.5(3.5) +3.4
- f(15) = 0.5(15) +3.4
- f(21.3) = 0.5(21.3) +3.4
Step-by-step explanation:
Put the given weight where x is in the function definition. You're only asked for the expression, not its value.
- f(2) = 0.5(2) +3.4
- f(3.5) = 0.5(3.5) +3.4
- f(15) = 0.5(15) +3.4
- f(21.3) = 0.5(21.3) +3.4
