A^2 = b^2 + c^2 - 2bc cos a
= 11^2 + 5^2 - 2*5*11 cos 40
= 7.86 to 2 DP's
to find the remaining angles use the sine rule:-
a / sin A = b / sin B so
7.857/ sin 40 = 11 / sin B
sin B = 11 sin40 / 7.857 = 0.8999
<B = 64 degrees
so <C = 180 - 64-40 = 76 degrees
2.32 x 10⁵ = 232000
This can be solved by multiplying 2.32 to the product of 10 multiplied 5 times.
10⁵ = 10 * 10 * 10 * 10 *10
10⁵ = 100,000
2.32 x 100000 = 232000
The given equation is the standard form of a decimal number. It is used to write down a very large or very small number easily.
There are a lot of standard forms. Like: Standard form of an equation and Standard form of a polynomial.
Answer:
$9.00
Step-by-step explanation:
27 divided by 3 = 9
Answer:
The answer is the second option or B, you have to divide the top number by the bottom number to get a unit rate.
Recall your d = rt, distance = rate * time
so... one train goes west and the goes the opposite way... alrite... so... notice, by the time 338 miles have been covered by both, it will have been "t" hours, and whatever "t" is, is the same amount of time the westbound train has been running as well as the eastbound train has been running.
now, let's say, since by "t" hours they've covered 338 altogether, so, if the westbound train has covered say "d" miles, then the eastbound train would have covered the slack from 338 and d, that is, "338 - d".

so, 2hours and 36 minutes.
