Answer:

The answer is C. a = -4,000 m

Step-by-step explanation:

If you subtracted 31,000 from 35,000, you would get 4,000 in a minute. Do the same for the rest, you would also get 4,000 m in a minute, so the answer would be a = -4,000 m

Answer:

A= -4,000m + 39,000

Step-by-step explanation:

If your doing the calculation it would be right

Given: -4,000m + 39,000

-4,000(1) + 39,000 = 35,000ft

-4,000(2) + 39,000 = 31,000ft

I don't know how to explain, but ig if you have the negative 4000, and you mutiply and add 39,000 it would decrease the ft

One term of (x+y)^m is 31,824x^18y^11<br> What is the value of m ?

alisha [4.7K]

Answer: The value of m is 29.

Step-by-step explanation:

Given that, One term of $(x+y)^m$ is $31,824x^{18}y^{11}$ ...(i)

We know that that (r+1)th term in $(a+b)^n$ is given by :-

$T_{r+1}=^nC_ra^{n-r}b^r$ ...(ii)

On comparing (i) with (ii) , we get

$a= x \text{ and } b= y \\n-r =18 \text{ and } r=11\\n=m$

i.e.

$m-r=18\Rightarow\ m-11=18\\\\\Rightarrow\ m=18+11=29$

Hence, the value of m is 29.

A man bought a lot for 1200 and sold it for 1500. his percent of gain based on his purchase was

jok3333 [9.3K]

Answer: The percent gain was 25%.

Step-by-step explanation:

Given, Cost price of lot = $1,200

Selling price of lot = $1,500

The percent gain = $\dfrac{\text{selling price- cost price}}{\text{cost price}}\times100$

⇒ Percent gain = $\dfrac{1500-1200}{1200}\times100\%$

$\Rightarrow\text{ Percent gain}=\dfrac{300}{1200}\times100\%\\\\\Rightarrow\text{ Percent gain}=\dfrac{1}{4}\times100\%\\\\\Rightarrow\text{ Percent gain}=25\%$
