Looking at the plot, i determined that the explorer 35's orbit is 11,400 km* across its long dimension. use this distance to find the orbit's semimajor axis in kilometers. * since the lines on the plot indicate lunar radii, i actually measured it to be 6.57 across, and then i multiplied by the radius of the moon: 1738 km.

6 hours 48 min

step-by-step explanation:

68÷5=13.6

13.6×30=408min=6 hours 48 min.

hope to and hope that my answer is brainliest.(follow me )

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
