Answer:
Option A
fraction numerator square root of 2 over denominator 2 end fraction
Step-by-step explanation:
The answer can be obtained using a calculator.
It corresponds to a notable identity
sin (45) =   / 2
 / 2
sin (45) = 0.7071
 / 2  = 0.7071
 / 2  = 0.7071

Answer:

Step-by-step explanation:
The formula relating distance (d), speed (s), and time (t) is
d = st
1. Calculate the distance
d = 269 s × 4.6 m·s⁻¹ = 1240 m
2.Calculate the track radius
The distance travelled is the circumference of a circle

 
        
             
        
        
        
Answer:
Step-by-step explanation:
james want to buy a sirt that cost 95 dollars. he only has 60 dollars saved.
if james gets paid 2 dollars a day how many days would he have to work to get 80 dollars.
solve for x
y=2x+60
95=2x+60
 
        
             
        
        
        
So you don't know the value of x, y, or z; all you're told is to solve for x. This is not impossible (even though it may seem like it). Your answer will have several variables in it, but in algebra you won't always have the complete answer.
Start with the equation: 4x - 5 / y = 2z
The first thing you'll want to do to it is try to get x alone on one side.
4x - 5 / y = 2z
       +5       +5 --> 4x / y = 2z +5
                               *y           *y --> 4x = y (2z + 5)
                                                        /4              /4   --> x = (y (2z + 5)) / 4 
Your final answer will be: x = (y (2z +5)) / 4
Hope it makes sense to you!!
