Answer: Number 1 is c=89 ft
Number 2 is b=3 cm
Step-by-step explanation: a²+b²=c²
For number 1, 39 ft is a and 80 ft is b so
39²+80²=c² so 39² is 39x39=1521 and 80² is 80x80=6400 so 6400+1521=7921
7921=c² and the square root of 7921 is 89 so c=89 ft
For number 2, a=1.6 cm and c=3.4 cm so 3.4²-1.6²=b²
3.4² so 3.4x3.4 which is 11.56
1.6² so 1.6x1.6 which is 2.56
11.56-2.56=c² and 11.56-2.56=9
Square root of 9 is 3 so b=3
So number 2 answer is b=3 cm

Answer:
S = 380 - 380*80%
Step-by-step explanation:
Given:
- The original price of the desk: $380
- Discount: 20%
So, the new price of the desk after discounting is:
380(100% - 20%)
= 380*80%
= 304$
The amount of money saved: 380 - 304 = 76$
Hence, the equation can be used to determine the amount of money saved is:
Saving = 380 - 380*80%
Hope it will find you well.
To solve you divide 68 by 16 and that gives you the price per square foot so that is $4.25, Now times 12 by that and the answer will be $51 dollars.
1. 3y
multiplying 3 and y together gets 3y
2. y-5
5 less implies that we subtract 5 from y
3. y+7
adding 7 to y, self-explanatory
4. 9y
same thing as #1
5. 
quotient of implies division, since number y is listed first, y is the numerator
