If you mean to translate it to Spanish it is División de, resta, multiplicacion, adición
Answer:
Step-by-step explanation:
y+30+2y=180
Add like terms
3y+30=180
Subtract 30 on both sides
3y=150
Divide by 3 on both sides
y=50
Now all you have to do i calculate the angles.
Answer:
3^13
Step-by-step explanation:
t= 2.25 secs
Step-by-step explanation:
Step 1 :
Equation for motion with uniform acceleration is v = u+ at
where v is the final velocity
u is the initial velocity
a is the acceleration due to gravity
and t is the time
Step 2 :
Here , v = 0 because at the highest point final velocity is 0.
u = 72 feet/sec
a = -32 ft/sec^2
We need to find the time t.
Substituting in the equation we have,
0 = 72 -32 * t
=> 32 t = 72
=> t = 72/32 = 2.25 secs
