Answer:
46
Step-by-step explanation:
The geometry can be modeled by a right triangle. The diagonal measure is the hypotenuse, and the height is one leg. The width is the other leg, and can be found using the Pythagorean theorem.
__
<h3>Pythagorean theorem</h3>
The relation between the leg lengths (a, b) and the hypotenuse (c) is ...
c² = a² +b²
Solving for b gives ...
b = √(c² -a²)
<h3>application</h3>
In this problem, we have c=55 and a=30. Then the width of the TV is ...
b = √(55² -30²) = √(3025 -900) = √2125
b ≈ 46.098
The width of the TV is about 46.
Try this option (this is not the only way!):
1. the rule: if 'number_1' - 'number_2' > 0, then number_1>number_2. If 'number_1'-'number_2'<0, then number_2>number_1.
2. according to the rule above: 9.36-9.359=0.001. 0.001>0, it means, 9.36>9.359.
Answer:
759 rolls
Step-by-step explanation:
Total rolls = 1265
Number of batches = 5
Since each batch hs the same number of rolls:
Number of rolls per batch :
1265 / 5
= 253 rolls per batch
Number of rolls in 3 batches :
253 * 3 batches
= 759 rolls
hi
You will only progress by trying yourself.
so I do the first, you do the rest.
You have to remplace x by 3
so first expression is : x²-4x
by remplacing "x" by it's value (3) we have :
(3)² -4(3) = 9 -12 = -3
Have a try for the rest and ask in comment if you dont understand.
