26.93 cm

Step-by-step explanation:

I believe this question uses the pythagorean theorem.

This is the pythagorean theorem formula:

c =

a = one of the legs of a triangle

b = one of the other legs of a triangle

c = hypotenuse

(I attached an image showing the legs and hypotenuse for further understanding :-) )

We already have a & b:

a = 10

b = 25

So this question asks us to find the crease of the paper, which is c.

To find c, we just plug in a & b into the formula and solve:

c =

c =

c =

c ≈ 26.93

(I rounded 26.93 from 26.92582404 because usually questions like these ask for the nearest hundredth)

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
