I’m not sure but i think the answer is 1124.28 to 2 decimal places.
Answer:
A and B
Step-by-step explanation:
Answer:
x+11 = 5x - 5
Step-by-step explanation:
x+
11
=
5
x
−
5
Subtract x from both sides
11
=
4
x−
5
Add 5 to both sides
16
=
4
x
Divide both sides by 4
x=4
First, convert 5 hours into minutes:
5 hours 60 min
------------ * --------------- = 300 min
1 1 hr
Next, find the unit rate in m/min:
9673.6 m
--------------- = 32.24 m/min
300 min
Now find the distance you can walk in 70 minutes at this rate:
32.24 m
------------- * 70 min = 2247 meters (answer)
1 min
You could walk 2247 meters (to the nearest meter) in 70 minutes.
In 2.44 seconds lindsey be 30 feet in the air.
<h3>What is Quadratic Equation?</h3>
A quadratic equation is a second-order polynomial equation in a single variable x, ax²+bx+c=0. with a ≠ 0 .
Given:
y= -16x²+33x+45
If the height is 30 feet.
30= -16x²+33x+45
-16x²+33x+45-30=0
-16x²+33x+15=0
16x²-33x-15=0
Solving the quadratic equation
x=-b±√b²-4ac/ 2a
x= 33 ± √2049/32
x= (33+ √2049)/32 and x=33-√2049/32
x=2.44 and -0.3833
