Mathematics
1 answer:
asambeis [7]2 years ago

Answer:

c = 26

Step-by-step explanation:

This is a right triangle, so we can use the Pythagorean theorem.

a^2 + b^2 = c^2

where a and b are the legs and c is the hypotenuse

10^2 + 24^2 = c^2

100 + 576 = c^2

676 = c^2

Take the square root of each side

sqrt(676) = sqrt(c^2)

26 = c

Let p and q be rational. Prove that p+q is rational
Contact [7]

Let p and q rational numbers (what does it means?), then, p and q coul be written as

p = \frac{a}{b},a, b \in \mathbb{Z}, b \neq 0\\\\q = \frac{c}{d}, c,d \in \mathbb{Z}, d \neq 0

then,

p +q = \frac{a}{b} + \frac{c}{d} = \frac{ad +bc}{bd}

and we know that ad+bc is an integer, so, p +q is a rational number.

Ber [7]

The expression that can be used to represent the list price of the smartphone is 5179.99 * (1- 25%) and the value is 3884.9925

<h3>What expression can be used to represent the list price of the smartphone? </h3>

The given parameters are:

Discount = 25%

Sales price = 5179.99

The expression that can be used to represent the list price of the smartphone is

Expression = Sales price * (1- discount)

So, we have:

Expression = 5179.99 * (1- 25%)

Evaluate

Expression = 3884.9925

Hence, the expression that can be used to represent the list price of the smartphone is 5179.99 * (1- 25%) and the value is 3884.9925
