I believe the answer would be a because its the one that doesn't change<span />
4.4 lies between 4.3 and 4.5
Answer:
1. She's probalaly going to use that one.
2. Her glass marble is problay going to break.
Step-by-step explanation:
She's picking random marbles right?
So we need to figure out which ones she picked out.
It says that she picked out 9 plasic marbles,
7 wooden marbles, 14 glass marbles,
and 10 wooden marbles. So she then, She put ONE
plasic marble on the table and then replaced
it with another one. Thinksmarter, And if you DID Thinksmarter,
you would know that answer one would be, she would use the other marble and probally not use the one on the table.
lets move on to answer 2. this one is very easy! sheputs a glass marble on the table and then pick/holds the medal one. therefore, the glass marble is round, so it will roll of the table and most likely break.
i hope this helps you and please mark me brainlieist
Answer:
The answer is 274.625
Step-by-step explanation: Volume is lxwxh so 6.5 x6.5 x6.5 is 274.625
Answer:
Ground speed = 131.25 km/h
Bearing = 92.68º
Step-by-step explanation:
If we imagine a triangle to depict the question with one side 134 km/h at an angle of 78º to the right of vertical (the plane's speed vector).
At the end, we have a line 21 km/h at an angle of 180 (from north), a vertical down from the end of the plane's vector. This vertex is angle B
This makes a triangle with the interior angle B of 78º.
The 3rd side is the ground speed which we can find using the Cosine rule:
b² = a² + c² - 2•a•c•cos(78)
b² = 134² + 21² - 2•134•21•cos(78)
b² = 17226.873
b = 131.25 km/h
The true course bearing" is the ground track. Thus;
Using the Sine rule to find angle A, we have;
(sin(A))/34= sin(78)/b
Thus,
sin(A) = (34 x sin(78))/131.25
sin(A) = 0.2534
A = sin^(-1)0.2534
A = 14.68º
Ground track = A + 78 = 14.68 + 78 = 92.68º
