8cm because 15cm-7cm= 8cm
Mathematically, t can take any value, so the domain would be R.
In reality (physics), I would expect t≥0.
Mathematically, the range is h≤98/5, and will become infinitely negative.
In reality, h is probably ≥0, making the range 0 ≤ h ≤ 98/5.
So it depends on whether you want to take the real-world limitations into account. Seen as how they are mentioned in the question prominently, I would do so.
Answer:
B)34
Step-by-step explanation:
9+3=12
12+4=16
16+6=22 6+6=12
22+12=34 12+12=24
34+24=58
Answer:
Step-by-step explanation:
1. Approach
To solve this problem, one wants to find the price of a product after its discount has been applied. The discount is 20% off, so the new price of the item is 80% of its original price (percent is out of 100 so if a an item is 20% off, it is 100 - 20 = 80; 80% the original price). To calculate the percent cost, one would divide the percent value by 100, and then multiply it by the price of the item.
2. Solving
The price of the new item is 80% of the price of the original item. To calculate the percent cost, cent, one would divide the percent value by 100, and then multiply it by the price of the item.
Therefore, the equation that will be formed is,
Substitute,
Simplify,
Answer:
43°
Step-by-step explanation:
The sum of all internal/interior angles of a triangle is always equal to 180°
Because of this, if the missing angle is x we can write the equation:
82°+55°+x=180° since the interior angles are given
Add like terms:
⇒ 137°+x=180°
Subtract 137:
⇒ x=43°
