Step-by-step explanation:

Here's an easy way to fold any rectangle of paper into a triangle with three sides the same length.

Fold the paper in half long-ways, then open it out flat.

Fold a bottom corner up to touch the fold line, making a sharp point on the other corner.

Now fold the two RED edges together.

Answer:

35.8

Step-by-step explanation:

$\frac{340.1}{9.5}$ = 358

We know that our answer can never be greater than 358 since the dividend

is 340.1 and the divisor is 9.5;

Also,

Both values are to one decimal places and we can use this to solve the problem;

9 can divide 340 in about 37 place with a remainder of 7,

So, it is appropriate to make the solution 35.8

If 30% of John's photographs were perfect, but 210 photographs were not perfect, then how many photographs were there in all?

anyanavicka [17]

If 30% were perfect, 70% were not perfect. So we know that 70% of the total number of photographs is 210.

p(70/100)=210 multiply both sides by 100

70p=21000 divide both sides by 70

p=300

So there are 300 photographs in all.
