Answer:
22 times.
Step-by-step explanation:
3 minutes = 180 seconds.
180 divided by 8 = 22.5
The light only flashed 22 times.
So if x = the <span>number of her total week's sales
Then </span><span>she made 5.5% straight commission on x
</span><span>5.5% of x= $560
</span><span>x*.055= $560
</span>
(hope this helped.)
81
substitute the given values for x and y into the expression
x²y² = (3)² × (3)² = 9 × 9 = 81
Answer:
=135.53°
Step-by-step explanation:
The bearing that the captain should turn is the angle difference between the two islands from the position of the ship.
Let C be the position of the ship, then
AB is c=160
AC is b=220
BC is a=200
We use the cosine rule as follows:
c²=a²+b²-2ab Cos C
160²=200²+220²-2×200×220 Cos C
25600=88400-88000Cos C
88000 Cos C=88400-25600
88000Cos C=62800
Divide both sides by 88000.
Cos C=62800/88000
=0.7136
C=44.47°
He should turn (180°-44.47°)=135.53°
