Answer:
8.4 (rounded to 1 dp)
Step-by-step explanation:
1) Identify the number of angles and sides given if you cannot use Pythagoras or SohCahToa.
2) You have 2 angles and 1 side, so you know you must use sine rule: <em>a </em>over sinA =<em> b </em>over sinB
<em>a</em> = side length, sin(A) = angle opposite side
<em>b</em> = side length, sin(B) = angle opposite side
3) This means:
13/sin(90) = x/sin(40)
4) rearrange for x:
x = 13/sin(90) * sin(40)
= 8.356...
5) Round to however many sig figs/dps they're asking for
Example: 1 dp
AB = 8.4
3 sig figs
AB = 8.36
Answer:
0.05 cents
Step-by-step explanation:
Given that George has $2.00 to spend at a store. He buys 3 cans of soda. Each can of soda costs 65 cents.
George has to use both multiplication and subtraction to find out the change
Spending at a store...$2.00
Costs of each can...$0.65
Cost of 3 cans....3×0.65= $1.95
Change he receives.... 2-1.95 = 0.05 cents
