Answer:
40.5 ft
Step-by-step explanation:
Solve for the time at which the balls meet, then find the corresponding height.
__
The balls will meet at the height such that the two values of h are the same.
-16t^2 +56t = h = -16t^2 +156t -248
0 = 100t -248
t = 2.48
Using the first equation to find h, we have ...
h = t(-16t +56) = 2.48(-16·2.48 +56) = 40.4736
The balls meet at a height of about 40.5 feet.
Answer:
The correct way to evaluate this expression is my following the order of operations PEMDAS
P=Paranthesis
E=Exponents
M/D=multiply/divide
A/S=add/subtract
The first step in 48-(29-17) is to do what's inside the paranthesis
48-12 (29-17=12)
Then you would subtract 48-12
48-12=36
Your final answer is
36
Hope this helps ;)
Answer:
8. the length is 88/5cm or 17.6cm
Step-by-step explanation:
8.perimeter =2L + 2W
when you convert the width 42/5 = 8.4
so 52 = 2L + 2*8.4
52= 2L + 16.8
52 - 16.8 = 2L
35.2 = 2L
divide both sides by 2
L = 17.6cm
Answer:
Order of operations was not used correctly, Do what is inside the parenthesis first. So use the distributive property first and not subtraction.
Step-by-step explanation:
6-4(3-6x)+12x
- 6-12+24x+12x
- -6+24x+12x
- -6+36x or 36x-6
