Answer:
cos L = 55/73
Step-by-step explanation:
The triangle KLM is a right angle triangle. The ∠M = 90°. The side KM = 48, LK = 73, and ML = 55. The ratio that represents the cosine of ∠L can be solved below.
The right angle triangle formed has an hypotenuse , opposite and an adjacent side. Using the SOHCAHTOA principle one can find the ratio that represent the cosine of ∠L.
opposite side = 48
adjacent = 55
hypotenuse = 73
cos L = adjacent/hypotenuse
cos L = 55/73
The answer to this question is X= -8
First do the distributive property and you get : -70 + 21x= -238
Then you add 70 to both sides : 21x= -168
Then you divide -168 with 21 and get the answer of -8
The answer is 12 scarves.
If the number N of scarves she can make is inversely proportional to the area <span>A of each scarf, then we have equation:
</span>N = x/A,
where x is the total area of the large piece of fabric she uses
First, we need to calculate what is the total area of the <span>large piece of fabric she uses (x):
It is given:
A = 4 square feet
N = 15
If </span>N = x/A, then: <span>x = A * N = 4 * 15 = 60 square feet
Now, we have to calculate the number of scarves she can make if the area of the scarf is 5 square feet.
So, it is given:
x = 60 square feet,
A = 5 square feet
</span>If <span>N = x/A, then: N = 60/5 = 12 scarves </span>
