Answer:
The dog biscuits are approximately 69% off.
Step-by-step explanation:
(1 - 0.69/2.23) * 100
(223/223 - 69/223) * 100
154/223 * 100 = 69%
So the first thing you want to do is solve what's in the parentheses (4^2-3) before you subtract, you get rid of the exponent by doing 4 times 4 (also known as 4^2) to get 16. you then subtract 3 from 16 getting 13. you then multiply7 by 13 to get 91, where you add the 8 to get 99 which would be the final answer
Height of the tree is 87 ft
Step-by-step explanation:
- Step 1: Find the height of the tree using trigonometric ratio tan.
Angle = 44°, adjacent side = 90 ft
⇒ tan 44° = opposite side/adjacent side
∴ Opposite Side = adjacent side × tan 44°
= 90 × 0.97
= 86.91 ft ≈ 87 ft
⇒ Height of the tree is 87 ft
The answer should be 16.10
