Answer:
2/6 more.
Step-by-step explanation:
You need to find a common denominator. In this case it was 6.
A = 5 km is your distance it is how far he traveled.
b = 3 km is your displacement it's the length in which he when north.
since triangles are similar
4/x = 7x/7
=》 4/x = x
=》x^2 = 4
=》 x = 2
for right triangles a^2 = b^2+c^2
DF^2 = 7^2+2^2 = 53
=》 DF = 7.28
perimeter of DEF = 7 +2+7.28 = 16.28
Answer:
Option D.
Step-by-step explanation:
Total number of cards = 52
Total number of cards of each suit (♠, ♣,♦, and ♥) = 13
The probability of getting a card of heart is



The probability of getting a card other then heart is

If Ming randomly draw a card from the deck 300 times, putting the card back in the deck after each draw, then the number of cards she will draw something other than a heart is

Close to 225 times but probably not exactly 225 times.
Therefore, the correct option is D.
