48 is what percent of 80
Gnesinka [82]

Answer:

48 is 60% of 80

Step-by-step explanation:

set it up as an equation

(100) 48 = \frac{x}{100} × 80 (100)

4800 = 80x (divide both sides by 80)

x=60

meaning that 48 is 60% of 80

McGill types 270 words in six minutes his paper is 630 words if he keeps waving at the same rate and how many more minutes when
Delicious77 [7]

Answer:

8 more minutes.

I think the perfect version in your question is:

<em>McGill types 270 words in six minutes his paper is 630 words if he keeps waving at the same rate and how many more minutes when McGill finish typing his paper</em>

Given that:

  • 270 words in six minutes <=> 1 minute = \frac{270}{6} = 45 words
  • His paper is 630 words

So, the total minutes he needs to finish the paper if  he keeps waving at the same rate is:

\frac{The number of words}{Number of words written in one minute}

= \frac{630}{45}

= 14 minutes.

So he needs 14 minutes to finish writing the paper, but he wrote 270 words in 6 minutes already, so it will take him 14-6 = 8 more minutes.

Hope it will find you well!

hi can i please have some help w/ these! i have my exam tomorrow!!! factoring algebra 2! worth 35 points!
prohojiy [21]

Answer:

11. 4x^{3}-10x^{2}+6x

Take out 2x ( greatest common factor )
2x(2x^{2}-5x+3)

Factor

2x(2x^{2} -2x-3x+3)

2x(x-1)-3(x-1)=(2x-3)(x-1)

Don't forget about the 2x we took out earlier

Solution to 11: 2x(2x-3)(x-1)

12. 16x^{2} -25y^{2}

This is the difference of squares, so let's use the formula...

a^{2}-b^{2}=(a-b)(a+b)

if, a=16x^{2} and b=25y^{2}

then, the Solution to 12 is:

(4x-5y)(4x+5y)

13. 3x^3-24

First of all, you must find the greatest common factor because there isn't anything else you can do.

3(x^3-8)

Now you can see the difference of cubes...

a^3-b^3=(a-b)(a^2+ab+b^2)

so, the Solution to 13 is:

3(x^3-8)= 3(x-2)(x^2+2x+4)
