Answer:
its a
Step-by-step explanation:
1.) D = 2pi * d * A / 360 degrees; Where:
pi = 3.14;
d = distance or 56,000,000 km (5.6x10^7 to standard notation)
A = angular size in degrees or .00688 degrees (.00012 radian to degrees)
D = 2(3.14) * 56,000,000 * .00688 / 360
= 6.28 * 385,280 / 360
= 2,419,558.4 / 360
D = 6,720.996 or 6,721
Therefore, 6,721 km. is the approximate diameter of Mars.
9 7/10 divided by 3/5 =
97/10 divided by 3/5 =
97/10 * 5/3 =
97/6 = 16 1/6
Answer:
<h2>3601 1/7</h2>
Step-by-step explanation:
First operation:
multiplication and division
Second operation:
addition
80 divided by 70 → 80 : 70 = 8/7
90 x 200 = 18000
90 x 200 divided by 5 → 18000 : 5 = 3600
80 divided by 70 plus 90 x 200 divided by 5 → 8/7 + 3600
1 1/7 + 3600 = 3601 1/7
