Answer: 3 or the whole backyard
Step-by-step explanation: In a hour she can rack 3 backyard. The question asked that how much of a backyard can she rake in 1 hour. She can rake the whole backyard in a hour.
Step-by-step explanation: A line, ray, or line segment (referred to as segment) that is perpendicular to a given segment at its midpoint is called a perpendicular bisector. ... In the diagram above, RS is the perpendicular bisector of PQ, since RS is perpendicular to PQ and PS≅QS. Additionally, since PS≅QS, point S is the midpoint of PQ.
The answer is y = -3x + 10.
The rest is not linear since the rest is not in the form of y = mx +b (a type equation for a line).
Have an awesome day! :)
Answer:
The distance of the boat from B is approximately 9.4 miles
Step-by-step explanation:
The location of light house B from A = 9 miles west
The distance of the boat from A = 4 miles
The bearing of the boat from A = NE65
We have;
4/(sin25) = 9/sin(B)
sin B = 9*sin(25)/4
B ≈ 71.969
a² = 4² + 9² - 2 × 4 × 9 × cos(180 - 25 - 71.969) ≈ 88.264
The distance of the boat from B, a ≈ √88.264 ≈ 9.4
