Of the 800 sweaters at a certain store, 150 are red. How many of the red sweaters at the store are made of pure wool? (1) 320 of

vitfil [10]

Answer:

Statement (2) ALONE is sufficient, but statement (1) ALONE is not sufficient.

Step-by-step explanation:

Judging by the first sentence, there are 800 sweaters, 150 of which are red. Hence 800 - 150 = 650 sweaters are not red.

Statement (1) mentions that 320 of the sweaters at the store are neither red nor made of pure wool. This implies that of the remaining 650 non-red sweaters, 320 of them are not made of pure wool. It tells us then that there are 650 - 320 = 330 sweaters that are not red and that are not pure wool. So, it does not give information about red sweaters at all, whether pure wool or not.

Statement (2) says 100 of the red sweaters at the store are not made of pure wool. This means out of all 150 red sweaters, 100 of them are not made of pure wool. Then we have that 150 - 100 = 50 red sweaters are made of pure wool. This is the response to the question asked.

Hence, we see that statement (2) alone is enough, while statement (1) alone is not.

Answer:

D. 19/2 D.-4/ $\sqrt{15}$ D.cos^2x look at explanation for last one

Step-by-step explanation:

1. Find the value of sec if cos delta = 2/19

because sec is basically 1/cos, and since it's Quad I there's nothing weird, you can just flip the fraction

therefore it's D. 19/2

2. Find the value of csc given cos delta = -1/4 and triangle is in third Quad

so cosine is adj over hypo: since the hypo can't ever be negative, the triangle must have a = -1 and c =4. to find bc use the c^2 = a^2 + b^2 to solve for b^2, and since it's third quad, b is negative, so b = - $\sqrt{15}$ 2. NOw that you know all three sides, finding csc is ez. So csc is hypo over opposite bc its opposite of sine, so therefore csc delta = $-4/\sqrt{15}$

3. simplify sin^2qcot^2

ok, so if cot is opposite of tan, and tan is sine over cos, cot must be cos over sine :D! SO cot^2 = $\frac{cos^2x }{sin^{2}x}$ . multiply that by sin^2 and the sines will cancel, leaving you with just cos^2x! sorry, I used x insead of q out of habit... oops!

4. determine the quad if sine delta = -1/4

sine is opposite over hypo, and as mentioned before, hypo can't equal to negative, so the opposite side must be negative. therefore, the triangle must lie in quad III or quad IV

ahem, these are your answers, idk why is it all D lol, I hope this helped. sorry this was so long!
