Answer:
B. CSCX= sinx / 1
D. tanx=
sin x / COS x
Step-by-step explanation:
A. sec x= 1/cos(x)
CSC X / 1 = sin(x)
B. CSCX
sinx / 1 = csc(x)
C. tanx= sin(x) / cos(x)
secx = 1 / cos(x)
D. tanx= sin(x) / cos (x)
sin (x) / cos(x)
you can use a calculator to try and multiply all of them so multiply 6x4 and then it will give you the answer then once you have that answer multiply it with the 4 im pretty sure but if not then sorry
Each day she eats 1/2 cups of rice. But we want to know how long it will take to each 2 cups worth. so lets make an equation.
.5x = 2
Divide both sides by .5
x = 4
So it will take 4 days to eat 2 cups of rice cereal.
Answer:
Step-by-step explanation:
distance = rate * time
rate = distance / time
= 2/3 mile divided by 1/2 hour
= 2/3 * 2/1 = 4/3 mph = 1 and 1/3 mph
His speed is 4/3 mph = 1 and 1/3 mph = 1.3 mph
So
1 mile = (4/3 mph) * TIME
Solving for Time T, it will take him t = 3/4 <--- the RECIPROCAL
and 3/4 hour = 45 minutes
Jack walks 1 mile in 45 minutes = 3/4 hour
