This is the answer ig 2.449 kilograms
Answer:
42
Step-by-step explanation:
This means 0.84 divided by 0.02
which equals to 42
the points mean that there is a zero
if a number has been written in that format of "point" then "number" without any number before the point, it means there is a zero there
if you need anything else clarified please do so in the comment section i would like to help more
Hope this helps and if it does mark as branliest answer thx
Answer: what?
Step-by-step explanation:
We have x+5y=3 => x= 3-5y
So 3y+2=4x
<=>3y+2=4(3-5y)
<=>3y+2=12-20y
<=>3y+20y=12-2
<=>23y=10
<=>y=10/23 => x=3-5(10/23)=19/23
Ok done. Thank to me :>
Answer:
w = π/2
Step-by-step explanation:
I used trig identities (double angle) to solve this problem.
Step 1: Rearrange problem
2cos²(w) - cos(w) - 1 = 0
2cos²(w) - 1 - cos(w) = 0
Step 2: Trig Identity
cos2w - cos(w) = 0
Step 3: Combine like terms
cosw = 0
Step 4: Solve
w = cos^-1(0)
w = π/2
I may have done it wrong so don't rely too much on me
