Answer:
this is a required answer.
+
= 
Explanation:
1/2 + 1/4 = ?
( 1/2 x 2/2 ) + ( 1/4 x 1/2 ) =
2/4 + 1/4 =
2 + 1 / 4 = 3/4
so, 1/2 + 1/4 = 3/4

Answer:
Marcus spent $6.36.
Step-by-step explanation:
First off, the fact that tax is included makes it easier for you, you don't need to worry about any multiplying!
Alright, so, he bought 2 candy bars for $0.79 EACH - that's 2 * $0.79 = $1.58.
Next, a drink for $1.49 and a bag of chips for $3.29. That's $1.49 + $3.29 = $4.78.
Now you add those two numbers up: $1.58 + $4.78 = $6.36.
Therefore, Marcus spent $6.36!
Answer:
400 ft
Step-by-step explanation:
h(t)= -16t^2 + 160t
The vertex is found at
h = -b/2a where b is the coefficient of t and a is the coefficient of t^2
= -160/(2*-16)
-160/-32
5
The time where the maximum occurs is at t=5
To find the maximum substitute into the function
h(5) = -16 (5)^2 +160*5
= -16*25 +800
=-400+800
= 400
The maximum height is 400 ft
