Answer:
<h2>True the speed S in in Feet/second</h2>
Step-by-step explanation:
In this problem we are required to solve for the speed of an object.
given that the expression to solve for the speed is expressed as
speed= distance/time
given data
distance=100 feet
time=2.5 seconds
substituting our given data into the expression we can solve for speed as
speed (S)=100/2.5
S= 40feet/seconds
upon substituting our data the speed S was found to be 40feet/s
True the speed S in in Feet/second
Answer:
Step-by-step explanation:
Start with our equation:
s=2(lw+wh+hl)
Plug in our values for l, w, and h:
s=2(12*9+9*2+2*12)
Simplify:
s=300

Answer:
(1) 1 and 7
Step-by-step explanation:
Hello!
We can solve by isolating the variable.
<h3>Solve</h3>
- 3(x - 4)² = 27
- (x - 4)² = 9
- √(x - 4)² = √9
- (x - 4) = ± 3
- x = 4 ± 3
There are two solutions, 1 and 7.
The answer is option 1: x = 7, x = 1.
The perimeter of the square is: 
ft
Step-by-step explanation:
The picture is attached with the answer.
the diagonal of a square divides it into two right angled-triangles.
We can use one of the triangle to find the length of side as the diagonal will be the hypotenuse of the triangle
Let a be the side of the square, then according to Pythagoras theorem
Dividing both sides by 2
Taking Square root on both sides
Now,
Hence,
The perimeter of the square is: ft
