Correct answer is third option ---C in edge
Answer:
0t=8
Step-by-step explanation:
3t+4=12+3t
3t-3t=12-4
0t=8
Answer:
the area is 20 in
Step-by-step explanation:
3 times 4 is 12. since we used 3 inches out of the 11, we can only multiply the 8 inches with 1. 8 times 1 is 8. 12+8=20.
Answer:
4.082 radians
Step-by-step explanation:
Here we want to convert 234° into radians.
To do it, we use the fact that pi radians is equal to 180°
Then we can write two equations:
x radians = 234°
3.14 radians = 180°
Where we want to find the value of x, which is the equivalent in radians to 234°.
Now we can take the quotient of these two equations to get:
( x radians)/(3.14 radians) = (234°/180°)
Solving this for x, we get:
x radians = (234°/180°)*(3.14 radians) = 4.082 radians.
The Pythagorean theorem tells you ...
... c² = a² + b²
... 13² = 12² + b² . . . . . fill in the given numbers
... 169 - 144 = b² . . . . .subtract 12²
... √25 = b . . . . . . . . . take the square root
... b = 5 . . . . . . The value of b you're looking for.

The numbers {5, 12, 13} make what is called a "Pythagorean triple" a set of integers that satisfies the relation of the Pythagorean theorem. These, and the triple {3, 4, 5} are often seen in algebra problems. It can be worthwhile to remember these numbers.
