Answer 1

Answer: Dear Mathproblemshurt, to be honest, you never really needed the number of websites in the world. It is for the fact that it asked for the percent of inactive websites and they gave you the fraction of inactive websites. Just do 2/3 to get 33.3%.

Answer:

it depends

Step-by-step explanation:

Shino's formula will work for any prism.

Angelo's formula will work for any prism whose base area can be found by ...

B = (1/2)ew

Angelo can use this formula for a triangular prism.

For a triangular prism, both may be correct.

For a prism of another shape, Shino is correct. (Angelo may also be correct, depending on the variable definitions.)

a teacher had 21 red pens. if the ratio of red pens to blue pens owned was 3:1 how many pens did she have in total

Answers

If the ratio of red to blue pens is 3:1, we can find the amount of blue pens by multiplying by 1/3, to get 21*1/3=7. There are 21 red pens and 7 blue pens, so there are 21+7=28 pens total.

Answer:

$(7x + 7)/((x-3)(x+4))$

Excluded values are 3 and -4

Step-by-step explanation:

To simplify the expression multiply to create a common denominator.

Multiply the first fraction by (x-3) and the second fraction by (x+4).

$(3)/(x+4) + (4)/(x-3)\n\n(3(x-3))/((x+4)(x-3)) + (4(x+4))/((x-3)(x+4))$

$(3(x-3))/((x+4)(x-3)) + (4(x+4))/((x-3)(x+4)) \n\n(3(x-3) + 4(x+4))/((x-3)(x+4))\n\n(3x - 9 + 4x + 16)/((x-3)(x+4))\n\n(7x + 7)/((x-3)(x+4))$

Excluded values are values which make the denominator 0. This means (x-3)(x+4) cannot be 0. This means x cannot be 3 or -4. These are excluded values.
