Answer:
(a) cannot be determined
(b) 44 cm^2
(c) 87 m^2
(d) 180 m^2
(e) 132 m^2
Step-by-step explanation:
(a) missing a horizontal dimension
__
(b) The difference between the bounding rectangle and the lower-left cutout is ...
(8 cm)(7 cm) -(3 cm)(4 cm) = (56 -12) cm^2 = 44 cm^2
__
(c) The difference between the bounding rectangle and the center cutout is ...
(13 m)(7 m) -(4 m)(1 m) = (91 -4) m^2 = 87 m^2
__
(d) The difference between the bounding rectangle and the two cutouts is ...
(20 m)(25 m) -(16 m)(20 m) = (20 m)(25 -16) m = (20 m)(9 m) = 180 m^2
__
(e) The difference between the bounding rectangle and the two cutouts is ...
(14 m)(12 m) -(12 m)(3 m) = (12 m)(14 -3) m = (12 m)(11 m) = 132 m^2
Answer:
true
Step-by-step explanation:
Answer: We want to find the acceleration needed to achieve a force of 25 Newtons.
The acceleration is:
a = 25N/m
By Newton's second law, we know that:
F = m*a
Force equals mass times acceleration.
So if we want to have a force of 25N, we replace F by 25N, so we get:
25N = m*a
Solving this for the acceleration, we get:
25N/m = a
Notice that we can't get the exact acceleration as we do not know the mass of the object, but we got a general formula where we can replace the mass of the object to get the exact acceleration.

Answer:
Step-by-step explanation:
Isolate the b from one side of the equation.
<u>First, subtract by 5 from both sides.</u>
<u>Solve.</u>
<u />
<u>Subtract.</u>
9-5=4
2b=4
<u>Divide by 2 from both sides.</u>
2b/2=4/2
<u>Solve.</u>
<u />
<u>Divide the numbers from left to right.</u>
4/2=2
Therefore, the correct answer is b=2.
I hope this helps, let me know if you have any questions.
