Answer:
gradient = 2
Step-by-step explanation:
Plot two points
(1 , 3) & (2 , 5)
We know that
[length of a circumference]=2*pi*r
diameter=90 cm-------------> r=d/2--------> r=45 cm
[length of a circumference]=2*pi*45----------> 90*pi cm
<span>with 1 revolution will go the length of the wheel</span>
if 1 revolution is-------------------> 90*pi cm
5 revolution is--------------------> X
X=5*90*pi----------> 1413 cm
the answer is 1413 cm
Answer:
-34/3
Step-by-step explanation:
2/3(1/4x-2)=1/5(4/3x-1)
2/12x-4/3=4/15x-1/5
1/6x-4/3=4/15x-1/5
1/6x-4/15x=-1/5+4/3
-1/10x=-3/15+20/15
-1/10x=17/15
x=(17/15)/(-1/10)
x=(17/15)(-10/1)
x=-170/15
x=-34/3
Answer:
10 O C
Step-by-step explanation:
X=9 how to solve: 72+48=8x+48
72=8x 8*9=72
