Answer:
LM = 8.75
Step-by-step explanation:
They’re asking us to find the hypotenuse (LM)
Given the angle measure of M which is 24° and it is adjacent to MK which is 8
so cos 24° = adj/hyp (adjacent / hypotenuse)
cos 24° = 8/hyp
hyp = 8 divided by cos 24°
hyp = 8.75
LM = 8.75
Option B makes the most sense, because if you follow the steps, they fit perfectly into each other!
Answer:the minimum rate is 1 mile per hour.
Step-by-step explanation:
Chanita wants to swim the 21-mile English Channel in 48 hours. Total number of miles that she covered on the first day is 9 miles. Total distance left for her to cover would be
21 - 9 =12 miles.
The next day, she has 12 hours of daylight to complete the remaining distance. Let x represent the minimum rate she has to swim on the second day to complete the distance.
Speed = distance/time
Therefore,
x ≥ 12/12
x ≥ 1
first off, let's put 8y - 5x = 11, in a slope-intercept form, so we can see what's its slope
so the slope of this line is 5/8, well then
Answer: it has no solution
Step-by-step explanation:
8x - 2y = 1 ..................... equation 1
-4x + y = 3 ...................... equation 2
solving the system of linear equation by substitution method . From equation 2 , make y the subject of the formula.
y = 3 + 4x .......................... equation 3
substitute equation 3 into equation 1 .
8x - 2(3 + 4x ) = 1
8x - 6 - 8x = 1
8x- 8x - 6 = 1
-6 = 1
this means that the equation has no solution
