Answer:
1:8
Step-by-step explanation:
1 hour for every 8 ounces gives a 1:8 ratio
1/5 is an expression that represents 1÷5= .2
Since the return decimal equivalent doesn't go on forever and has a finite end, this is a member of the rational number set.
Answer:
3, and b
Step-by-step explanation:
1. x =3
Because you have 3 little squares for one x
2. x= -12
b) 15+6=21
Answer:
Δ MAN
reason: ASA
Step-by-step explanation:
if you look at the congruency marks you can see that ∡F ≅ ∡A and we know that ∡N ≅ ∡N
markings also show us that sides UF ≅ MA
therefore, we know two angles and one side for each triangle
H=+15 m
v=+5 m/s
Ball hits the ground when h(t)=-15m
h(t)=-9.8t^2+vt+h
=>
-15=-9.8t^2+5t+15
9.8t^2-5t-30=0
Solve for t, using quadratic formula,
t=-1.513 or t=2.023
reject negative root due to context, so
t=2.023 seconds
2)
h(t)=-16t^2+20t+8
a. height before pitch is when t=0, or h(0)=8
b. highest point reached when h'(t)=-32t+20=0 => t=5/8 seconds
c. highest point is t(5/8)=-16(5/8)^2+20(5/8)+8=47/5=9.4 m
d. ball hits ground when h(t)=0 => solve t for h(t)=0
=> t=-0.3187 seconds or t=1.569 seconds.
Reject negative root to give
time to hit ground = 1.569 since ball was pitched.
