We know that: sin Ф = cos(π/2 - Ф) ↔ sin Ф = cos(90° - Ф)
Then:
sin 42° = cos(90° - 42°) = cos 48°
IF sin 42° = 2/3, the cos 48° = 2/3
6,003,041,016 = 6.003041016 x 10^9
So
x (4%)
y (5%)
x=y+2400
0.04x+0.05y=294
Once you solve them, x=4600 and y=2200
so 4%= $4600
5%= $2200
Answer:
A. $0.75
Step-by-step explanation:
0.75×2=1.50 (1.50 price of 2 hotdogs)
4-1.50= 2.50 (2.50 is the price of 2 sodas)
1.50 + 2.50= $4
Answer:
40
Step-by-step explanation:
b = base
h = height
Area of triangle = 1/2 * b*h
1/2 * 8 * 10
= 40 units^2
Hope it helps
