57 x 817 = 46569

46569 divided by 100 = 465.69

817-465.69 = 351.31

Answer : 351

<em>Explanation : 57 times 817 equals to 46569 and then you divided by 100 . Then it equals to 465.69 . To find out the how many more students were enrolled you have to subtract 465.69 from 817 and then you get 351.31 which you round to 351 . </em>

Answer:

520

Step-by-step explanation:

Past number of pupils: p

Increase of 57% = 1.57

Present number of pupils = 817

p x 1.57 = 817

p = 817 divided by 1.57 = 520.382

rounded to the nearest whole number = 520 (this is why the question says "about" how many...)

Right triangle ABC is similar to right triangle DEF. If the side lengths for triangle ABC are 15, 20, 25, respectively, which va

Answer:

$A = 15$ $B = 20$ $C = 25$

$D = 30$ $E = 40$ $F = 50$

$D = 3$ $E = 4$ $F = 5$

Step-by-step explanation:

Given

Similar Triangles: ABC and DEF

$A = 15$

$B = 20$

$C = 25$

Required

Determine the sides of DEF

No options were given, so I will solve on a general terms.

Since both triangles are similar, then the following relationship exists.

DEF = ABC * n

i.e.

$D = A * n$ $E = B * n$ $F = C * n$

Where

$n = Scale\ Factor$

Assume n = 2.

So, we have:

$D = A * n$

$D =15 *2$

$D = 30$

$E = B * n$

$E = 20 * 2$

$E = 40$

$F = C * n$

$F = 25 * 2$

$F = 50$

Assume $n = \frac{1}{5}.$

So, we have:

$D = A * n$

$D =15 *\frac{1}{5}$

$D = 3$

$E = B * n$

$E = 20 * \frac{1}{5}$

$E = 4$

$F = C * n$

$F = 25 * \frac{1}{5}$

$F = 5$

So, the possible sides are:

$A = 15$ $B = 20$ $C = 25$

$D = 30$ $E = 40$ $F = 50$

$D = 3$ $E = 4$ $F = 5$

Can somebody please help me with this question?!?!?!

scoray [572]

I don't think there's any answer. It says that the absolute value of x-7 is negative 2, but an absolute value is always positive. So there's no value for x that can make the equation a true statement.
