Given the following triangle, if c = 18.6 and m B = 43°, find the length of BC (side a) to the nearest whole number.
Answers
Answer:
= 14
Step-by-step explanation:
Given a right angled triangle with hypotenuse length c =18.6 and ∠B = 43°.
We can use the trigonometric forms of a right angled triangle,
That is;
Cos 43 = Adjacent/Hypotenuse
That is;
Cos 43 = BC/AC = a/c
Therefore;
Cos 43 = a/18.6
a = 18.6 × cos 43
= 13.603
= 14
Therefore, BC or a is 14 (to the nearest whole number)

And if y=0, x would have to be -6 (which is impossible)
Final answer:
The equation representing the total amount of flour Otto used in his recipe is y = 6 + x. Here, x and y should be non-negative real numbers, and y will always be at least 6.
Explanation:
The total amount of flour that Otto used in his recipe is represented by the equation y = 6 + x, where x is the quantity of white flour used, and 6 is the amount of whole wheat flour used. This equation comes from the concept of sum in mathematics, where we combine or add up different quantities to get a total.
The constraint on the value of x (the amount of white flour) is that it must be a "non-negative real number". This is because, in real-life context, it's not possible to use a negative amount of something. Similarly, y (the total amount of flour) must also be a non-negative real number and must be at least 6 (since we always have 6 cups of whole wheat flour in the recipe).

Answer:
-2r+8
Step-by-step explanation:
4r-7r+8+r
5r-7r+8
-2r+8
-2r+8
The first step is to combine like terms. These would be 4r, -7r, and r since they have the same variable. This gives you -2r. Since there are no other like terms to combine, you end up with -2r+8

To answer this question we have to first determine how many times 100 can go into 13,300. To find this we do the following:
$13,300/$100 = 133
Now we simply multiply the result by $2.74:
$2.74*133 = $364.42.
Finally we just multiply that by the total number of payments which are (monthly payment, 12 months in a year, for 4 years).
$364.42*(12*4) ---> $364.42*48 = $17,492.16.
The correct answer is choice 4.) 17,492.16
I hope this helps, Regards.
