Hello!

To solve this we can use the Pythagorean Theorem, a²+b²=c², where a and b represent the legs and c represents the hypotenuse. We will solve below.

1²+3²=c²
1+9=10

We have 10=c². We can isolate c by finding the square root of 10.

√10≈3.16

Therefore, the other side could be 3.16.
---------------------------------------
Note that 3 could also be the hypotenuse. We could solve the equation the other way around to see what the other side could be (it could be the hypotenuse or a leg).

9-1=8
√8≈2.83

Therefore, the length of the third side could be either 3.16 or 2.83.

I hope this helps!

The area of this composite figure is 533 square inches.
The formula for a rectangle is lw, and the formula for the area of a triangle is 1/2bh. After plugging the values into these formulas, we have to add the values all together to get the final area.

1. The square on the inside is 8 x 8 = 64

2. The triangle's area is 8x9x1/2= 72 x 1/2 = 36

3. there are 4 triangles so 36 x 4 = (or 72 x 2 ) = 144 :)

Stan has made a $125.30 monthly deposit into an account that pays 1.5% interest, compounded monthly, for 35 years. he would now

The annuity of the monthly deposit into an account that pays 1.5% interest, compounded monthly, for 35 years is $333.71

<h3>What is annuity?</h3>

An annuity is a series of payments made at equal period of time.

future value = annuity x [(1 + i)ⁿ - 1] / i

annuity = $125.30

i = 1.5% / 12 = 0.00125

n = 35 years x 12 months = 420

future value = $125.30 x [(1 + 0.00125)⁴²⁰ - 1] / 0.00125

future value = $69,156.049 ≈ $69,156.05

annuity = [i x (present value)] / [1 - (1 + i)⁻ⁿ]

i = 1.5% / 12 = 0.00125

n = 20 years x 12 months = 240

present value = $69,156.05

annuity = (0.00125 x $69,156.05) / [1 - (1 + 0.00125)⁻²⁴⁰]

annuity = $86.45 / 0.25904

= $333.71
