Answer:

A. 15 You are correct.

Step-by-step explanation:

The formula used to find the hypotenuse in this problem is called the Pythagorean Theorum. The formula is as follows: a^2 + b^2 = c^2. Or, you can say that the hypotenuse is equal to: c = the square root of a squared and b squared added together. This might sound confusing in the start, but here's all you have to do. a = 9, and b = 12. 9 squared is 81. 12 squared is 144. 144 + 81 = 225. The square root of 225 is 15, because 15 x 15 = 225. So 15 is your answer.

Answer:

A. 15

Step-by-step explanation:

Ooh, look! This triangle is a Pythagorean triple! Without even needing to use a formula, I can tell that you are correct and the answer is A. 15.

It's based off of a 3-4-5 right triangle, because 9-12-15 simplifies to that if you divide every term by 3. It's basically just a bigger version of a 3-4-5 triangle! Isn't math cool:)

Martin runs 100 meters in 15 seconds. What is the equation for d, the distance in meters that Martin covers per second?

Assoli18 [71]

The correct answer is C. d × 15 = 100

Martin runs 100 meters in 15 seconds
When we multiply the distance he runs every second by the amount of seconds, the outcome must be 100. Since he runs 15 seconds, we must multiply his distance per second by 15 and the outcome has to be 100.

Else said:
$d \times 15 = 100$

Solve for x.<br> 2x2 – 40x + 200 = 0

Eduardwww [97]

Answer:

5.1

Step-by-step explanation:

you subtract 200 from 0 which =-200 then you can multiply 2 and 2 which =4 so then it's 4 -40x=-200 then u add -4 and -204 which is -204 so then the equation is -40x=-204 then u divide -204 by -40 to get 5.1 so x = 5.1. not sure if I did this right but whatevs

I really need help with the question above! This is my second time asking. Am I right? If not please give me the correct answer

Hey there! :D

Pay attention to the given angles.

We know that a circle is equal to 360 degrees.

We know two angles, and the other 2 are the same measure.

170+44= 214

Subtract that from 360, since that is what the circle equals.

360-214= 146

Divide that by two, since there are 2 equal angles left.

146/2= 73

<DOB= 73 degrees.

You were correct, so good work!

I hope this helps!
