Steven needs to type a 2000 word document for work. If he can type 125 words in 2 minutes, how long will it take to type the who
Dimas [21]

Answer:

32 minutes

Step-by-step explanation:

This can be calculated with some good old division and multiplication:

Step 1 - Divide the word count by the number of words every 2 minutes:

2000 ÷ 125 =  16

Step 2 - Multiply the 16 by the 2 minutes:

16 * 2 = 32

The 16 is the number of words it would take and multiply the 16 by 2 will tell us the number of minutes it would take for the whole document to be written.

So it would take him 32 minutes.

Hope this helps!

aleksley [76]

Solution: The equation is , 2 =3 ×\frac{2}{3}

Out of the given options :

 The number 2 is 3 times the size of 2/3.

For example, if and b are any two real numbers, a≠0,∧b≠0 then

→a= b×(a/b).

Or

A/B=k, then A=Bk→A=B×A/B replacing k by A/B.

Polynomials question 7 Thanks!
sammy [17]

Answer:

After arranging the terms of given Polynomial from highest to lowest the Polynomial becomes 4x^5+2x^3-7x^2-15.

Step-by-step explanation:

Given:

4x^5+2x^3-15-7x^2

We need to arrange the terms of given Polynomial from highest to lowest.

Now on seeing the above polynomial we can say;

The terms of polynomial can be arrange according to the highest number of exponent.

Form above expression we can say the first highest exponent term is 4x^5

Hence the First term is 4x^5.

Now we can see the second highest exponent term is 2x^3

hence the second term would be 2x^3.

now we can see the third highest exponent term is -7x^2

hence the third term would be -7x^2.

now we can see the fourth term is -15

hence the fourth term would be -15.

Hence After arranging the terms of given Polynomial from highest to lowest the Polynomial becomes 4x^5+2x^3-7x^2-15
