Answer:
$84.87
Step-by-step explanation:
The mover costs $69
23% of 69 is $15.87
add the two together to get $84.87
(or just multiply 69 by 1.23)
Answer:
cos(400)
Step-by-step explanation:
Useful things:
Cofunction identity: sin(x)=cos(90-x)
Sine and cosine have period of 360 degrees.
So sin(50)=cos(40) by cofunction identity.
Since cosine has period of 360 degrees then cos(40)=cos(360+40).
That simplifies to cos(400).
Answer:
f= 0.7
Step-by-step explanation:
Multiply by reciprocal on both sides: 4/3 * 3/4(5f-3) = 3/8 * 4/3 f
Then, you are left with: 5f-3 = 1/2
Then you subtract by three on both sides to get: 5f=3.5
Finally, divide by 5 on both sides to get: f=.07
Answer:
50m/s
Step-by-step explanation:
We assum the direction the baseball is travelling to the bat is the positive direction at 20 m/s and is hit in the opposite at a faster speed. The change in velocity is the final velocity minus the initial velocity:
The change in velocity is 50m/s
Your answer would be 6 ft
you already know that Alyssa is 1 1/2 feet tall which is 1/4 of tammy's height.
so you will take 1 1/2 x 4 (the number of 1/4's needed to get a whole number) = 6 feet
