Answer:

\huge\boxed{\bf\:2\sqrt{5} \:\: units }

Step-by-step explanation:

We have a figure given in the shape of a square with a diagonal (x) passing from one edge to another. We need to find the measure of its diagonal if the side of the square is \sqrt{10} units.

We know that, a square has all equal sides. Then, all the sides of the square will be equal to \sqrt{10} units.

Now, let's find the diagonal.

To find the diagonal of a sqaure from one of its sides, we need to know the formula ⟶ Diagonal = side \bf\:\sqrt{2}.

By using this formula,

Diagonal (x)\\= side *\sqrt{2} \\= \sqrt{10} *\sqrt{2}\\ = \sqrt{5*2*2} \\= \boxed{\bf\:2\sqrt{5} \:units}

→ The diagonal of the square = 2√5 units.

What interest is needed to earn $137.50 on a deposit of $500 for five years if it earns simple interest?
sineoko [7]

Answer:

5.5%

Step-by-step explanation:

Given data

Simple interest =  $137.50

Principal= $500

time = 5 years

We want to find the rate  R

Simple interest= PRT/100

137.50 = 500*R*5/100

137.50=2500R/100

cross multiply

137.5*100= 2500R

13750= 2500R

divide both sides by 2500

R= 13750/2500

R=5.5%

Hence the rate is 5.5%
