Answer: At four o’clock the minute hand is on the 12 and the hour hand is on the 4. The angle formed is 4/12 of the total number of degrees in a circle, 360. 4/12 * 360 = 120 degrees
Explanation:
Answer: 4 miles per hour.
Explanation:
We can calculate her feet per second: 75 ft/12 sec is 6.25 ft/sec
Then convert to miles per hour. 1 mph = 1.46667 ft/sec
Divide 6.25/1.46667 = 4.261353951 mph
Round that to 4 ¹/₄ mph or, as per the directions in this question, "to the nearest mile per hour.
4 mph.
It is also possible to get a similar answer by changing the feet to a fraction of a mile, (about 0.142mi) and the time to a fraction of an hour (about 0.00333) and dividing those numbers, but that may be doing too much!
Answer:
1 and 9
Explanation:
Taking Square on both sides:
(sqrt(4x))^2= (x-3)^2
4x= x^2 + 9 - 6x
x^2 - 10x + 9= 0
Solving Quadratic Equation
x^2 -9x -1x +9=0
x(x-9) -1(x-9)=0
(x-1)(x-9)=0
x=1 x=9
This is pretty much common sense (no offense) think about it like this. The question says “most businesses and MANY homes” there’s no way it’s false because many many homes have personal computers
