Answer:
x=2475/31 Exact form
x=70.838 Decimal form
x=7026/31 Mixed Number form
i didnt know which one you wanted
Answer:
Step-by-step explanation:
you have a right triangle,
a^2+b^2=c^2
10^2=4^2+b^2
100=16+b^2
100-16=b^2
84=b^2
b=9.16
Answer:

Step-by-step explanation:
0.75 is equivalent to three quarters, or (3/4).
3/4 would be the fraction. -37 would be the whole number.

Hope this helps.
Answer:
3.5 hours
Step-by-step explanation:
Distance = 21 miles
Speed * time
Speed * time = distance
Tom speed = 2 mph
Brian = 4 mph
Let time = t
Brian distance + Tom's distance = total distance
4t + 2t = 21
6t = 21
t = 21 / 6
t = 3.5 hours
The height is represented by h = -16t² + 4t + 20 and There is only one solution, because the solutions indicate time and time cannot be negative.
<h3>How to solve vertical motion models?</h3>
We are given the vertical model of the diver's jump as;
h = -16t² + vt + s
where;
h is height
t is time
v is velocity
s is distance
A) We are given;
Distance; s = 20 ft
velocity; v = 4 ft/s
Thus;
h = -16t² + 4t + 20
B) The solution of the model is gotten from;
-16t² + 4t + 20 = 0
Solving this quadratic equation gives;
t = 1.25 seconds or -1 second
C) B. There is only one solution, because the solutions indicate time and time cannot be negative.
