Answer:
the best option would be to swim
Step-by-step explanation:
Hello! To solve this problem we must follow the following steps.
1. remember the concept of uniform motion with constant speed, which establishes the following equation
where
t=time
x=distance
V=speed
2. Calculate the time it takes to swim and calculate the time it takes to walk
walking:
x=10mile
v=5milles/h
swimming
x=1mile
v=3milles/h
3. Compare both results and choose the one with the least time.
as you can see it takes less time swimming, so this would be the best way
Equation describes a sloping line. For any
equation ax+by+c = 0, slope is .<span>X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 30/5 = 6.Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 30/-3 = -10.Slope is -5/-3 = 1.66666666666667.<span> Equation in slope-intercept form: y=1.66666666666667*x+-10.</span></span>
M to the power 4 squared minus 23
Answer:
Yes
Step-by-step explanation:
A polygon is a 2D figure with at least three straight sides and angles. A pentagon has five sides and angles, so it qualifies as a polygon.
I hope this helped ^^ Good luck
Answer: It would take 9 hours for 4 painters to paint 720 feet of fence.
Step-by-step explanation:
1.) Calculate the time needed to paint the 720 ft fence with 2 painters.
a.) Divide 720 by 280 to get how many times greater 720 is than 280.
720 / 280 ≈ 2.57
b.) Multiply the time needed to paint the 280 ft fence with 2 painters by 2.57.
7 * 2.57 ≈ 18
2.) Calculate the time needed to paint the 720 ft fence with 4 painters.
a.) Assuming that each painter paints the same amount of fence, divide the time in half, as 4 painters is double the original amount, so it would take half of the time.
18 / 2 = 9
