Answer:
Part A:
given that cos β = 3/5
that means the base line is 3 and the hypotenuse is 5
Note that, The base line 3 is adjacent to β and opposite to α.
Sin α = opposite / adjacent
sin α = 3 /5
Part B:
α and β are complementary angles
Answer:
5,318 millions of barrels
Step-by-step explanation:
Subtract Japan's number of barrels from the US' to find the difference:
7,297.4 - 1,979.4 = 5,318 millions of barrels
Base pay + (rate * sales) = total pay
b + r(400) = 388
b + r(700) = 454
b = 388 - 400r
now sub into 2nd equation
388 - 400r + 700r = 454
-400r + 700r = 454 - 388
300r = 66
r = 66/300
r = 0.22...22% is the rate
substitute for r
b + 400r = 388
b + 400(0.22) = 388
b + 88 = 388
b = 388 - 88
b = 300
so ur equation is : y = 0.22x + 300
y = 0.22(2600) + 300
y = 572 + 300
y = 872......so her salary when selling $2600 worth of stuff is $872
Answer:
50
Step-by-step explanation:
first of all thimk about how many 12s there is in 60 (which is 1hr=60) and thats 5, so multiply 5 by 10 because in each 12 mins its 10 km which gives you 50 as the answer
Calculate the monthly payment:
195,000 x ( (0.05/12)x1+0.053)^12)/(1+0.053)^12-1)
Monthly payment = 1,082.84
Multiply monthly payment by 12 to get one year: 1082.84x 12 = 12994.08
Now multiply by 30 years:
12994.08 x 30 = 389822.40
The answer is $389,822
