You would subtract. 3 abd 7/8 minus 1 and 3/8 equals 2 and 4/8. If you simplifie it you would get 2 and 1/2. Your answer would be 2 and 4/8 or 2 and 1/2

I promise I will mark as brainiest if a speed of a car increase its average speed in a journey of 200 miles by 5 mile/hour the j
jok3333 [9.3K]

Answer:

\large \boxed{\sf \ \ \ \dfrac{\sqrt{4025}-5}{2}=29.22144... \ \ \ }

Step-by-step explanation:

Hello

<u>Let's note the original speed of the car v</u>

it means that in 1 hour he is going v miles

so to go 200 miles it takes ( in hour)

\dfrac{200}{v}

If the speed of the car is v+5 than to go 200 miles it takes (in hour)

\dfrac{200}{v+5}

and this time is one hour less so we can write

\boxed{\sf \ \ \dfrac{200}{v+5}=\dfrac{200}{v}-1 \ \ }

We can multiply by v(v+5) both parts of the equation so

200v=200(v+5)-v(v+5)\\\\200v=200v+1000-v^2-5v\\\\v^2+5v-1000=0

\Delta=b^2-4ac=5^2+4*1000=4025\\\\ \text{There are potential solutions }\\\\\ \ \ \ \ x_1=\dfrac{-5-\sqrt{4025}}{2}\\\\\ \ \ \ \ x_2=\dfrac{-5+\sqrt{4025}}{2}

Only one is positive and this is is

x_1=\dfrac{\sqrt{4025}-5}{2}=29.22144...

So the original speed is 29.22144... mph

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

The nth term of a sequence is represented by 3n4−10/6n4+7 . What is the limit of the the nth term as n becomes increasingly larg
Cerrena [4.2K]

Answer:

<h3>1/2</h3>

Step-by-step explanation:

Given the limit of the function expressed as;

\lim_{n \to \infty} \frac{3n^4-10}{6n^4+7} \\

To take the limit, we nee to divide through by the highest power of n first

\lim_{n \to \infty} \frac{3n^4/n^4-10/n^2}{6n^4/n^4+7/n^4}\\= \lim_{n \to \infty} \frac{3-10/n^2}{6+7/n^4}\\= \frac{3-10/(\infty)^2}{6+7/(\infty)^4}\\= \frac{3-0}{6-0}\\= \frac{3}{6}\\ = \frac{1}{2}\\

Hence the limit of the the nth term as n becomes increasingly large is 1/2

<h3>What is Cost Price?</h3>

This refers to the price which a seller or a merchant purchased a good and this would be a good determinant to find out the selling price so that he could make a good profit.

<h3>Selling Price</h3>

This refers to the price which a good is sold and there are several factors which are taken into account such as:

  • Expenses
  • Cost Price, etc.

Mathematically, the<em> profit= </em>Cost price - Selling Price (Expenditure)
