345 * 60 = 20700. So it converts to 20700 ft/hr
Answer: the base is 28 inches. The altitude is 9 inches
Step-by-step explanation:
Let h represent the altitude of the sign.
Let b represent the length if the base of the sign.
The warning sign is triangular in shape.
The formula for determining the area of a triangle is expressed as
Area = 1/2bh
The base of the sign is 9 inches longer than the altitude. This means that
b = h + 9
If the area of the sign is 266 square inches, it means that
266 = 1/2 × h(h + 9)
266 × 2 = h(h + 9)
532 = h² + 9h
h² + 9h - 532 = 0
h² + 28h - 19h - 532 = 0
h(h + 28) - 19(h + 28) = 0
h(h + 28) - 19(h + 28) = 0
(h + 28)(h - 19) = 0
h = 19 or h = - 28
Since the height cannot be negative, then h = 19
b = h + 9 = 10 + 9
b = 28
Answer:
2x² - 3x
Step-by-step explanation:
multiply the outside with the inside brackets
x × 2x = 2x²
x × (-3) = -3x
Answer:
According to the scatter plot given, and studying that, we get that the most likely number of trees planted in 12 hours will be 13 trees.
Hope my answer helps :)
You must be 5 feet. Yes you can go on the ride if you are 5 feet because 60 inches equals 5 feet
