Answer:

Option (D)

Step-by-step explanation:

Pythagoras theorem states,

(Hypotenuse)² = (leg 1)² + (leg 2)²

(13)² = (5)² + (12)²

By the converse of Pythagoras theorem,

If we draw two sides 5cm and 12cm of a triangles with a right angle between them, third side 13 cm will fit to form a right triangle.

Therefore, Option (D) will be the answer.

If you travel 40 miles at 45 miles per hour, how many minutes will that take you?

GenaCL600 [577]

Ok so im not good with words and math, but i am going to try my best to explain it. first you will take 45/60 which is the 45 miles per hour. next you will put it equal to 40/x. x is how many minutes. they are set equal to each other because they are the same ratio. (i honestly dont know why you cross multiply, but you just do). you then multiply 40*60 and 45*x. this gives you 2400=45x. you then divide both sides by 45 and get 53 1/3 minutes. or 53 minutes and 20 seconds

A salesperson earns a salary of $700 per month plus 2% of the sales. Which inequality correctly represents the total sales if th

My name is Ann [436]

Answer:

C. $x\geq 55000$

Step-by-step explanation:

Let x be the total monthly sales.

We have been given that a salesperson earns a salary of $700 per month plus 2% of the sales. The salesperson want to have a monthly income of at least $1800.

This means that 700 plus 2% of total monthly sales should be greater than or equal to 1800. We can represent this information in an equation as:

$700+(\frac{2}{100})x\geq 1800$
