Answer:
i think is 20 0r 22
Step-by-step explanation:
Answer: arc length = r * θ = (3 in) * (135°) = (3 in) * (3π / 4 rad) = 9π / 4 in.
Step-by-step explanation:
Answer:
Below.
Step-by-step explanation:
If its a right triangle it will obey the Pythagoras theorem.
17^2 = 289
11^2 + 15^2 = 121 + 225 = 346
- so NOT a right triangle.
Answer:
y = 4/3
Step-by-step explanation:
y = 3^x+1
Substitute -1 for x.
y = 3^(-1)+1
y = 1/3 + 1
y = 1/3 + 3/3
y = 4/3
For this problem, there are two situations. To solve this, let's construct an algebraic equation for each. Let's find the total cost. Let x be the number of yards.
Situation 1: Cost = 4x + 5
Situation 2: Cost = 6x +2
Now, both situations have the same cost. So,
4x + 5 = 6x + 2
6x - 4x = 5 - 2
2x = 3
<em>x = 3/2 or 1.5 yards</em>
