Find the length of a leg

1 answer:

4 0

2 corners are both 45 degrees, meaning that they are both the same length.

For this we use the pythagorean theorem, but a bit modified:
a^2 + a^2 = c^2
2a^2 = 256

Solve for a:
a^2 = 128
a = 8 √2

One leg is equal to √128 or 8 √2.

Verdich [7]

Answer:

See below

Step-by-step explanation:

The first one 'cubes' the denominator AND the numerator:

(-2/5)^3 = -2/5 * -2/5 * -2/5 = -8/125

The second one 'cubes' only the denominator:

-2/5^3 = -2 / (5 * 5 * 5) = - 2 / 125

9 Josie parents opened a college

mixer [17]

Answer:

$1,281.00

Step-by-step explanation:

We start by calculating the value $50 added each month after the first month

= $50 × 11

= $550

Calculation:

First, converting R percent to r a decimal

r = R/100 = 5.5%/100 = 0.055 per year.

P = Principal = 500 + 550

= $1050

Calculation:

First, converting R percent to r a decimal

r = R/100 = 5.5%/100 = 0.055 per year.

Solving our equation:

A = 1050(1 + (0.055 × 4)) = 1281

A = $1,281.00

Therefore, there would be $1,281.00 after 4 years.
