We need to look at 2 similar triangles
1) big one: legs - a,b, and hypotenuse - c
2)small one: legs - h,s, and hypotenuse - b.
Corresponding sides:
hypotenuse - c and hypotenuse - b,
big leg - b and big leg - s,
small leg - a, and small leg h.
?(/b(big leg, big triangle)= b(hypotenuse, small triangle )/s (big leg, small triangle)
? should be hypotenuse of the big triangle, c.
Answer is second one c.
Answer:
It should be red or green 125 times
Step-by-step explanation:
The first thing to do here is to calculate the probability of selecting a red or a green marble
Total number of marbles = 7 + 3 + 2 + 8 = 20
Probability of selecting a red marble is 7/20
Probability of selecting a green marble is 3/20
The probability of selecting a red or a green marble = Probability of selecting a red marble + Probability of selecting a green marble = 7/20 + 3/20 = 10/20 = 1/2
Now our selection spans 250 times, the number of times it should have been a green or a red marble = The probability of selecting a green or a red marble * number of selection times = 1/2 * 250 = 125 times
Answer : The 5th day = 3 Celsius
Explanation:
the average of the first 4 day is 8
Which mean the combine temp on the first 4 day is 8 x 4 = 32
Now on the first 5 day the average temp is 7
Then the combine temp on the first 5 day is 7 x 5 = 35
Find the 5th day
4 days combine temp + 5th day = the combine temp of 5 days
32 + 5th day = 35
5th day = 35-32
5th day temp = 3C
Answer: 394.8
Step-by-step explanation:
if Amid needs 32.9 m for one tent he will need
32.9 x 12= 394.8 m for 12 tents
