The hypotenuse is 20 ft
Step-by-step explanation:
- Step 1: This is a right triangle, so the trigonometric ratio cosine can be used to find the length of the hypotenuse. Given side opposite to ∠B, AC = 18 ft and ∠A = 40°,
cos 40° = adjacent side/hypotenuse = AC/AB = 18/AB
⇒ AB = 18/cos 40° = 18/0.76 = 23.5 ft ≈ 20 ft
Hello! First, let's add 1 to the tax rate in decimal form. 6.5% is 0.065. 1 + 0.065 is 1.065. Multiply that number by 25 to get 26.625 or 26.63 when rounded to the nearest penny. The total cost of the movie is $26.63.
Note: If a question asks for the total cost with tax, always add 1 to the tax rate in decimal form. That way, you will get straight to the answer and not have to do any complicating work.

Ok. Since the fractions aren't the same, we have to make them common. They both have 30 in common.
4/10 = 12/30 I multiplied this 4 by 3 since I did 10 times 3.
2/3 = 20/30 Same with this one. Since 3 times 10, 2 times 10
Now you add the things to get 32/30, simplify to 1 2/30, and again to get 1 1/15.
Now add
3+2+1/15 = 6 1/15
He used 6 1/15 bags of fertilizer.
The answer is B. -3
hope this helps!
