Answer:

there for the answer is C=45

Step-by-step explanation:

The 27 red cars make up 60% of the total collection, here is the equation

to be solved:

27 = 60% of C C is the total cars in the collection

27 = .60 C

27 / .60 = C

45 = C

5!=5*4*3*2*1;6!=6*5*4*3*2*1 What is the value of 4^4/4!

german

Answer:

$\frac{32}{3}$

Step-by-step explanation:

If 5! is equal to 5 × 4 × 3 × 2 × 1 and 6! is equal to 6 × 5 × 4 × 3 × 2 × 1, then 4! is equal to 4 × 3 × 2 × 1. Thus, 4! = 4 × 3 × 2 × 1, which can simplify to 24. 4! = 24.

$4^{4}$ is basically 4 × 4 × 4 × 4, which can simplify to 256.

So, $\frac{4^{4}}{4!}$ = $\frac{256}{24}$ . $\frac{256}{24}$ can simplify to $\frac{32}{3}$ . Therefore, $\frac{4^{4}}{4!}$ = $\frac{32}{3}$ .

Three friends were born in consecutive years. The some of their birth years is 5982.find the year in which each person was born

posledela

A+b+c=5982
find the average of the three friends
5982/3=1994
add and subtract one to find the average
1994+1=1995
1994-1=1993
add all the years together to check
1993+1994+1995=5983

Find the exact value of the trigonometric expression given that sin u = − 8 17 and cos v = − 24 25 . (Both u and v are in Quadra

Rashid [163]

Answer: sin u = -5/13 and cos v = -15/17

Step-by-step explanation:

The nice thing about trig, a little information goes a long way. That’s because there is a lot of geometry and structure in the subject. If I have sin u = opp/hyp, then I know opp is the opposite side from u, and the hypotenuse is hyp, and the adjacent side must fit the Pythagorean equation opp^2 + adj^2 = hyp^2.

So for u: (-5)^2 + adj^2 = 13^2, so with what you gave us (Quad 3),

==> adj of u = -12 therefore cos u = -12/13

Same argument for v: adj = -15,

opp^2 + (-15)^2 = 17^2 ==> opp = -8 therefore sin v = -8/17

The cosine rule for cos (u + v) = (cos u)(cos v) - (sin u)(sin v) and now we substitute: cos (u + v) = (-12/13)(-15/17) - (-5/13)(-8/17)

I am too lazy to do the remaining arithmetic, but I think we have created a way to approach all of the similar problems.
