Answer: No, it is not sufficient to know that opposite sides of the garden plot are congruent and parallel to determine that the garden plot is rectangular.
Step-by-step explanation:
1. You have the following information given in the problem:
- Opposite sides of the garden plot are congruent.
- Opposite sides of the garden plot are parallel.
2. Therefore, keeping the information above on mind, you can conclude that the description is about a parallelogram, but to determine that it is rectangular, you need to know that the four interior angles measure 90° and the diagonals are congruent.
"In our class we have 3 books. My teacher says that we need to increase that number of books by 1/8 with each student. If they are 7 students how many books will the class have now?"
Ok there's a quick example but here is how to solve it.
You need to make the 3-fraction friendly and put a one under it
1/3 and now you can multiply 3/1 x 7/8.
Which will now give you 21/8 and simplified it will be 2 5/8
So final answer would be 21/8 = 2 5/8.
Answer:
The correct option is A: 4.29 N.
Step-by-step explanation:
The magnetic force is given by:
Where:
q: is the charge = 7.12x10⁻⁶ C
v: is the speed = c/2 = 1.5x10⁸ m/s
B: is the magnetic field = 4.02x10⁻³ T
θ: is the angle = 90° (the speed is perpendicular to the magnetic field)
Hence, the force on the charge is:
Therefore, the correct option is A: 4.29 N.
I hope it helps you!
Answer: b=40
Step-by-step explanation:
- She divided by 3 instead of the GCF.
- She didn’t complete step 4 and use the distributive property to be sure the expressions are equivalent.
- She didn’t undistribute the GCF from the original expression.
