Answer:
x=0
Step-by-step explanation:
"y varies directly as x," means that when one increases/decreases, the other does the same thing
so when y decreses by 4 from 16 to 12, x decreases by 4 too
4-4=0
D) y=x+1
I am not sure though.
Answer:
Part 1: 25 feet long
Part 2: 8 feet high
Step-by-step explanation:
A^2 +B^2 =C^2
C is the hypotenuse which you are finding for part 1.
You are finding B for part 2.
Part 1:
15^2 + 20^2 = C^2
225+400=C^2
625=C^2
Sqrt(625)= C
25=C
Answer for Part 1 is 25 feet long.
Part 2:
6^2 + B^2 = 10^2
36 + B^2 = 100
Subtract 36 from both sides.
B^2 = 64
B= sqrt(64)
B= 8
Answer for Part 2: 8 feet high
X = 90 degreees, so you take 47 and 90 add them together and you get 137 degrees. you need 180 to make a triangle, so you subtract 137 from 180. the answer for y is 43 degrees. hope that helps
Step-by-step explanation:
13.8% = 0.138 in decimal form.
Percent means 'per 100'. So, 13.8% means 13.8 per 100 or simply 13.8/100.
If you divide 13.8 by 100, you'll get 0.138 (a decimal number). Read more below on this webpage.
As you can see, to convert from percent to decimal just divide the percent value (13.8) by 100, and remove the "%" sign.
