It is the first option i think
Set up proportion 170/180=x/1 than cross multiply 170x=180 divide both sides by 170 answer 0.944 so 94% remains
<span>He started with 184 digital cameras and 56 manual cameras
Work--> </span>d + m = 240 equation 1 (d-82) = 3(m-26) equation 2d - 82 = 3m - 78d - 3m = 82 - 78d - 3m = 16 equation 2 simplified d + m = 240d - 3m = 16 subtract equation 1 from equation 2--------------- -4m = -224 m = -224/-4 m = 56 d + m = 240d = 240-md = 240-56d = 184
Answer:
1/14
Step-by-step explanation:
1 - 5/7 = 7/7 - 5/7 = (7-5)/7
Subtract. 7 - 5 = 2
= 2/7
Now we have to multiply 2/7 and 1/4
We get 2/7 x 1/4 = <em>1/14</em>
Circumference
C=2πr
C=2(3.14)(7)
C=(3.14)(14)
C=43.96
