Answer:
4 kg
Step-by-step explanation:
so 1.6 * 4 is 6.4 so you just double check if you want
4 + 1.6 which is 1/4 of 6.4 will be 5.6 (matches with the question)
4 + (1.6*4) (indicates it's full) = 10.4( also Matches with the question)
there is another way by setting up an equation. let me know in comments if you want to see it that way
We know that
[volume of the ramp]=[area of the base]*height
area of the base=37.4 yd²
height=5 yd
so
[volume of the ramp]=[37.4]*5----> 187 yd³
the answer is
the volume of the ramp is 187 yd³
Answer:
x=9
Step-by-step explanation:
.5x+.7 = .3x+2.5
-.7 -.3x
.2x=1.8
/.2 /.2
x=9
.5(9)+.7=5.2
.3(9)+2.5=5.2
51.44÷80%=64. 3$$
Because (100-20=80%)
