A right triangle has legs of 30m and 40m. What is the PERIMETER of the triangle?

choices:
A.) 120m

B.) 70m

C.) 1200m

D.) 50m

Answers

Answer 1

Answer:

A

Step-by-step explanation:

We know that we are dealing with a right triangle. Look at the legs given to us, 30m and 40m. That looks familiar doesn't it? In fact, this quite resembles the 3-4-5 special right triangle.

We can simply scale the legs by 10 to find the last side of the triangle.

[tex]3*10=30\\4*10=40[/tex]

and therefore, the last side of the right triangle must be:

[tex]5*10=50[/tex]

Great! Now we have all the sides of the right triangle. We just have to add them up:

[tex]30+40+50=120[/tex]

Therefore, the perimeter of the triangle is 120m. A.

I hope this helps! Let me know if you have any questions :)

f) The angles marked a and c are complementary.

Step-by-step explanation:

A complementary angle is and angle that has a sum of 90 degrees. A vertical angle is 2 angles facing each other, that are completely identical. 180 degrees is the sum of a strait line. 90 degrees is a right angle.

B. The zeros of the function f(x) are -3 and 1.
C. The minimum of the function f(x) is 8.
D. The axis of symmetry of the function f(x) is x = -1.

Answers

C is the incorrect answer

Example Given


Find a or b

a = 20. b = ? c = 25



Find b or a. c^2 - a^2 = b^2



25^2 - 20^2 = c^2

If an impulse travels 100 m/s, about how long will it take the impulse to travel 10 meters?

Answers

Answer:

0.1 seconds

Step-by-step explanation:

10/100=0.1

Answer:

1/10th of a second or .1seconds

Step-by-step explanation:

100m/s meaning its traveling 100 meters a second.

Since its going to travel 10 meters, it will take 1/10 the time since 10/100 = 1/10

The time is in seconds so it will take them 1/10th of a second.

Answers

Answer:

A because (0,-6) is the y-intercept so you start at the point you know. Then because slope is a rise over run fraction the slope can also be written as 2/1 which is rise 2 over 1.

Step-by-step explanation:

Answer:

A, cuz (0,-6) is the y-intercept. You start at the point that is familiar to u. Then cuz slope =  rise over run, simplify the slope which is 2/1.
