Answer:

A, C

Step-by-step explanation:

Let's use a different benchmark for this: 1/2. Half of 5 is 2 1/2, so 3/5 is clearly bigger than 1/2 (since 3 is bigger than 2 1/2). Half of 3 is 1 1/2, so 1/3 is clearly smaller than a half (since 1 is smaller than 1 1/2). We have

1/3 < 1/2 < 3/5

Which, of course, implies that 1/3 is less than 3/5, and by being smaller, 1/3 is closer to 0 than to 1.

What is the fourth term in the binomial expansion of (2x – y) 7?

nata0808 [166]

Answer:

$(7C4) (2x)^4 (-y)^{7-4}$

And replacing we got:

$35 (2^4) x^4 (-y)^{-3}$

And then the final term would be:

$-560 x^4 y^3$

Step-by-step explanation:

For this case we have the following expression:

$(2x-y)^7$

And we can use the binomial theorem given by:

$(x+y)^n =\sum_{k=0}^n (nCk) x^k y^{n-k}$

And for this case we want to find the fourth term and using the formula we have:

$(7C4) (2x)^4 (-y)^{7-4}$

And replacing we got:

$35 (2^4) x^4 (-y)^{-3}$

And then the final term would be:

$-560 x^4 y^3$

Rufina [12.5K]

Answer:

W=50M

Step-by-step explanation:

Since there are 18 workers per 900 minerals, divide out to simplify.

STARTING EQUATION: 900m=18w

SIMPLIFY: divide both sides by 18.

SIMPLIFIED: 50m=1w
