Answer: 80 feet
Step-by-step explanation:
We can write these as fractions and do cross multiplication with the numerator being the height of the object while the denominator being the length of the shadow:
5 * 128 = 8x
640 = 8x
80 = x
Thus, the height of the lighthouse is 80 feet tall.
Answer:
the coordinates will be (0,9) (-8,0) and the equation will be y=(9/8x)+9
Im not 100% sure but if im right please mark me as brainliest
w = 7 7/8
w + 1/8 = 8
First, subtract 1/8 from both sides of the equation
- 1/8 - 1/8
